Description:
[0001]    I am hereby claiming whatever benefits accrue to the present invention and its application from 2 (two) provisional patent applications filed earlier by the present inventor at the USPTO offices. The first provisional patent application, “Renewable Rotary Skin Lancet”, was filed Jun. 10, 2006, and was granted an application No. 60/812,202. The second provisional patent application, “Shouldered Lancet Needle Carriers”, was filed Dec. 6, 2006, and was granted an application No. 60/873,411. 
         [0002]    The present invention is a tool used to perform the task of lancing a person&#39;s skin. The commonly-applied term used for such tools is “Lancet”. Thus the name “Lancet” is used. Because the target of the Lancet is “Skin”, that terminology is included. The present invention includes as one of its components a “Rotary” wheel, so that name is included. The wheel is made so it can be replaced and is in that way “Renewable, so that name is included. The title “Renewable Rotary Skin Lancet” was chosen to adequately describe the type and function of the present invention.

       COMPARISON BETWEEN THE REFERENCED PATENTS AND THE RENEWABLE ROTARY SKIN LANCET 
       [0004]    U.S. Pat. No. 7,175,641 B1 is for a single-needle type lancet, whereas the present patent application is for a multi-needle lancet. Because of this there is a distinct difference between the two lancet devices. 
         [0005]    U.S. Pat. No. 7,105,006 B2 for is a single-needle lancet, whereas the present patent application is for a multi-needle lancet. Because of this there is a distinct difference between the two lancet devices. 
         [0006]    U.S. Pat. No. 7,087,068 B1 is for a single-needle lancet, whereas the present patent application is for a multi-needle lancet. Because of this there is a distinct difference between the two lancet devices. 
         [0007]    U.S. Pat. No. 6,949,111 B2 is for a single-needle lancet, whereas the present patent application is for a multi-needle lancet. Because of this there is a distinct difference between the two lancet devices. 
         [0008]    U.S. Pat. No. 6,887,253 B2 is for the needle-depth, adjustment-mechanism for a single-needle lancet, whereas the present patent application is for a multi-needle lancet, which, although it too embodies a needle-depth adjustment, makes use of an entirely different mechanical process to revise the needle depth. Because of this there is a distinct difference between the two lancet devices. 
         [0009]    U.S. Pat. No. 6,660,018 B2 is for a multi-needle type lancet, as is the present patent application. However, U.S. Pat. No. 6,660,018 B2 embodies several needles, each parallel to the others, and all of which effectuate a different location of skin puncture at essentially the same moment within close distances from each other, and the device may be repeatedly used, possibly leading to unwanted infections when used on different subjects or at different times. In comparison, the present patent application is for a multi-needle lancet arranged in a non-parallel, radial fashion, each of which can be used only alone, and only one time, limiting the possibility of unwanted infections. Because of these facts, there is a distinct difference between the two lancets. 
         [0010]    U.S. Pat. No. 6,228,100 1 is for a device which has some similarities to the device in the present patent application. The similarities are these. Both have a multitude of needle carriers arrayed in a radial fashion from a common center. However, the needle carriers are distinctly different. Both have a mechanism for driving the needle carriers radially into the target&#39;s skin, but the mechanisms for doing this are distinctly different. Both have a mechanism for rotating a needle-carrying wheel, but the mechanisms for doing this are distinctly different. 
         [0011]    There are other distinct differences. Some of them are listed following. 
         [0012]    The ratcheting parts of the device of U.S. Pat. No. 6,228,100 1 are unchangeably clustered in a circle close to the axial center of said device, and this means that only a very-limited, unchangeable number of ratcheting points can be built into a device constructed under the limitations of the design of U.S. Pat. No. 6,228,100 1. In said design there must be a ratcheting point accompanying each needle in said device, and the restriction on numbers created by the ratcheting-number restriction means that only a comparatively few needles can be built into that patented device. In comparison, the present patent application will embody many ratcheting points, actually named Cogs in the present invention, by which to advance each needle in its turn, and, being near the outer periphery of the needle-bearing wheel of said present device, comparatively, many more needles can be made available for use in a device of practical size in the device of the present patent application. In short, the greater the diameter of the Cog Wheels and Needle-Carrier Wheels in the present patent application, the more Needle Carriers will be available in it, whereas, in the device shown for U.S. Pat. No. 6,228,100 1 only the same, limited, maximum number of Needles will ever be available, no matter how large the device is constructed. One of the primary objectives for the device in the present patent application was having a multitude of Needles available in it, and in the present invention the number available is limited only by the device needing to be built of a practicable physical size. Although the number of needles available in the present invention can be from sixty count to 100 count without seeming to be overly large, the optimal number will not be known until prototype units of the present invention can be made and tested. In comparison, the number of needles fixedly available in the device in U.S. Pat. No. 6,228,100 1 seems to be six needles as only six ratcheting points are shown on the drawings, this irrespective of the fact the drawings show fifteen needles, an impossible number if the drawings are correct with respect to the ratcheting points. 
         [0013]    Further, U.S. Pat. No. 6,228,100 1 is for a multi-needle type lancet device in which the location of the puncturing needle in a finger-shaped indentation makes it impractical to attempt a puncture on a flat segment of skin such as is the target for blood samples used by some persons who have an aversion to injuring their fingers, and who want to use their arms or thighs for obtaining blood samples. Notable examples of that sort of person might be musicians who play stringed instruments, or shop clerks whose hands are prominent in their work. The soreness and blue bruising evidenced by persons who stick their fingers several times daily cannot be masked, and in some persons they can be hurtful and ugly. The needle points of the device of U.S. Pat. No. 6,228,100 1 might be unable to project as far as the location of the skin at an arm or thigh, and even if they could, the depth of penetration would seem to be ungovernable. In comparison, the device in the present patent application projects the needle point outside the bounds of the device case, making it usable on fingers, thighs, arms, or the skin on nearly any part of a human body. 
         [0014]    Further, U.S. Pat. No. 6,228,100 1 has no mechanism for adjusting the distance its needle points project into the skin when blood samples are being obtained. This is unfortunate due to the fact that on different persons the skin thickness can vary considerably. For example, a carpenter who has practiced the carpentry trade for many years may have thick, calloused skin on his or her fingers due to the years of contact with rough objects and the beating the fingers would have taken from missing the nail and hitting a finger instead. Clerks in a linen store would most likely have thin skin on the fingers because their work would not likely have caused damage to their finger&#39;s skin. Older people sometimes sustain a thinning of the skin all over their body as they age. Children will mostly have very thin and very sensitive skin. Children will have a natural dread of having any sort of needle penetrating their skin, and may more strenuously object when a needle is used which either penetrates too deeply than is necessary to obtain a sufficiently large blood sample, or even worse, insufficiently deep to obtain any blood at all, thereby necessitating multiple punctures while seeking the needed amount of blood. The inventor of the device being presently applied for is a diabetic who currently must use a lancet device for obtaining blood samples four times each day, and one of the primary considerations of said inventor in designing the presently-applied-for Renewable Rotary Skin Lancet was to provide an effective means of adjusting the depth of needle penetration. The present patent application embodies such a mechanism. Said inventor knows of no other lancet device having a similar adjusting mechanism. 
         [0015]    Further, the device described in U.S. Pat. No. 6,228,100 1 does not appear to embody an easily-removable disc, wheel, or cartridge in which the needle-containing objects are located. It appears that the individual needle-carrying parts must be manually removed and replaced one at a time if multiple uses of the said device&#39;s needle spaces are to exist. Replacing the needles one by one would entail several objectionable processes. The opportunity for the needles, exposed as they would be, to become septic, is objectionable. The chance of inadvertent finger sticks as the needle devices are either being removed or replaced, and the attendant chance of unwanted infections, is absolutely undesirable in the present day of scourges such as the AIDS disease. 
         [0016]    Further, there will be many users of a lancet device who would be incapable of safely removing used lancets one at a time and then replacing them. It is true that the device described in U.S. Pat. No. 6,228,100 1 might be able to be used until its supply of needles is exhausted, but it should then be discarded in entirety to maintain the safety which it should maintain, and doing so would make the use if this device overly expensive compared to many other types of lancet devices. In comparison, the present patent application uses an easily-removable wheel for containing the Needle Carriers and Needles, and it can be easily replaced by a factory-made, replacement needle-wheel manufactured and assembled in a sterile environment. 
         [0017]    Further, the present patent application&#39;s needles are at all times, except at the moment of skin puncture, shielded from the possibility of contamination from touching, or from infections arising from an accidental finger sticking during human contact with the used or replacement needle-bearing wheel. And, once used, its needle-bearing wheel can be thrown away without using a sharps container, and without creating an undue hazard. This, of course, results in a comparatively economical use of the device of the present application. The device shown in U.S. Pat. No. 6,228,100 1 seems to leave a used needle point exposed until a new needle is rotated into the indented edge space. This would mean that accidental, unwanted, possibly hazardous, punctures could take place on that device. The needles used in this type of device are so small as to be insignificantly visible, and a person desiring to use the device could unknowingly easily place a finger in the indentation before it has been newly cocked, and that might be very dangerous. 
         [0018]    Further, the process of replacing the needle-bearing wheel in the device of the present application is simple enough to safely perform that only very young children and physically or mentally incapable persons would need to be excluded from the personal use of the device. 
         [0019]    Further, the device of U.S. Pat. No. 6,228,100 1 features a protective covering over the point of its needles. These covers must be removed one by one before the needles are used for punctures. U.S. Pat. No. 6,228,100 1 makes use of an included, physically-separate device for removing the protective covers. This process would be a burden to anyone using said device, particularly young or elderly users, or anyone else having limited physical or mental capacities. In comparison, the present patent application does not require needle point coverings to maintain safety in its use, because the needle points in said present application are hidden away from human contact until the time they are used momentarily to make a skin puncture, and they are then immediately retracted from exposure, so there is no need for a separate device to prepare the needles for use. Needing to have available an altogether separate device in order to make use of the primary lancet device is likely to be troublesome. The device of the present application has no such problem connected to its use. 
         [0020]    Further, The enclosing case of the device of U.S. Pat. No. 6,228,100 1 is a bulky unit, with protruding parts. This will make it inconvenient to grasp in the hand of the user, and bulky for carrying in a pocket or purse. The enclosing case of the device in the present application is a flat shape, and, when it is constructed in a practicable size, is able to be easily grasped in the user&#39;s hand, and able to be fitted easily in a pocket or purse. 
         [0021]    Further, because the needles used in a desirable lancet must be made with a very small diameter in order to be as comfortable to use as is possible, when the skin of a person is punctured in order to obtain a droplet of blood for testing, quite often the flow of blood from the puncture wound must be encouraged to appear by squeezing the skin around the puncture soon after it is made. The device in the present application embodies a raised rim around the hole thru which the device&#39;s needles project at the moment they are making a puncture. This rim, when pressed against the target skin, will leave a briefly-visible indentation, showing exactly where the puncture has occurred. If the blood does not quickly appear, the spot which must be squeezed to start it flowing is easily determined from said indentation In comparison, the device in U.S. Pat. No. 6,228,100 1 has no such raised rim, and, as a result the exact point of puncture may be indeterminable when blood does not immediately appear. The result may be that an undesirable second, or even third, puncture may be required to release blood, and an undesirable deeper penetration of the puncturing needle on the patented device may ordinarily be necessary for effective use of that patented device. 
         [0022]    Whereas the device in the present application makes use of a trigger button which moves a sort of holed gate away from the striking end of the Hammer, and this releases the Hammer so the Needle Carrier and Needle will be impelled toward the target skin, the device in U.S. Pat. No. 6,228,100 1 employs an altogether different sort of releasing mechanism. 
         [0023]    In the device of the present application there is a choice of two different types of systems used to advance the needle-bearing wheel one needle space forward after using the prior needle for a puncture. Two systems are included so that the manufacturer may use whichever one will be most easily produced and/or most effective in its use. The needle-advancement process used in the device in U.S. Pat. No. 6,228,100 1 makes use of an entirely dissimilar mechanism. 
         [0024]    In the device of the present application there is a detent device employed to accurately center the projecting needle in the aperture in the case containing said device so that there will be no interference between the case and the needle when the needle is projected. The device in U.S. Pat. No. 6,228,100 1 has no such detent centering mechanism. 
         [0025]    There are several needle carrier designs shown in the drawings made for the device of the present application. Four of these embody devices in the needle carrier and/or the needle carrier&#39;s wheel whereby accidental reuse of a used needle in forestalled. And, with the use of one of those four needles this is true even if the used needle carrier wheel is accidentally reinserted for use. It is impossible, given the scant information provided for the needle devices in U.S. Pat. No. 6,228,100 1 to determine whether its needle devices embody any means to disallow accidental reuse of its used needles. In any event, that patent&#39;s text and drawings do not seem to specify such means. 
         [0026]    Any commercially-sold lancet device will be used by a wide range of people. Diabetics, for example, use several lancets daily for determining the glucose content of their blood, and their insulin intake is then based on the blood tests. Diabetes is prevalent in people all ages, all genders, all races, and all ages, and it is reportedly becoming more prevalent. Diabetes is probably the largest reason for a person to have regular blood tests requiring obtaining a drop or two of blood, and sufferers of this disease must regularly test their blood. Modern lancet devices are the best way to obtain the blood for testing. But it is almost mandatory that the lancet devices used can be used with uncomplicated methods. As regards the device in U.S. Pat. No. 6,228,100 1, it is overly complicated to use, so much so that it is likely that its use is too complicated for many people requiring a lancet&#39;s use. On the other hand the device in the present application can be successfully and safely used by a young child, a blind person, or even a one-armed person, so long as there is present in them a moderate amount of intelligence and physical ability. The only operations required in using the device in the present application are opening the case, loading a needle-carrier wheel, cocking the hammer, pressing the firing button, and when the needle supply is exhausted, again opening the case, and replacing the used needle carrier wheel. All these are easily performed, making its use practical for a wide range of people. 
         [0027]    U.S. Pat. No. 5,645,555 carries the word “Rotary” in its name, and, in fact, the part used to penetrate a patient&#39;s skin does rotate within the device in the process of performing its intended function. However, it differs from the device contemplated in the present patent application in the following ways. The device in U.S. Pat. No. 5,645,555 embodies a knife-type edge to effectuate entrance into a skin surface in a cutting fashion. The present patent application embodies a group of needles which effectuate entrance into a skin surface in a puncturing fashion which is much less intrusive and much less traumatic than the imposition of a cut in the skin. Further, the device in U.S. Pat. No. 5,645,555 embodies only one cutting part which is able to be repeatedly used. This fact means it can lead to unwanted infections when used on different subjects or at different times. The present patent application embodies a group of needles each of which can be used but once, thereby limiting the possibility of infections. 
         [0028]    U.S. Pat. No. 5,476,474 is simply an earlier embodiment of many of the same features as U.S. Pat. No. 5,645,555, and its differences from the device contemplated in the present patent application are essentially the same. 
         [0029]    U.S. Pat. No. 4,794,926 is in fact a lancet device having a rotating disc with fingers. Each finger has a single tooth which is used to puncture a person&#39;s skin for the purpose of obtaining a sample of blood. U.S. Pat. No. 4,794,926 differs from the device in the present application in these ways. U.S. Pat. No. 4,794,926 uses a sharpened tooth. The present application uses needles. The tooth used by the device in U.S. Pat. No. 4,794,926 will cause a larger hole in skin than a needle, and this will cause greater trauma and more emission of blood than may be desirable. The tooth used by the device in U.S. Pat. No. 4,794,926 projects from the case of its device perpendicularly to the plane of the case body. In the device of the present application the needle projects from a very small opening and in the same plane as the body of its case, and the positioning of the puncture being made can more exactly be selected because more of the skin area will be visible when the device in the present application is used since less of the device case blocks a view of the skin area. It appears that the device in U.S. Pat. No. 4,794,926, as constituted, will permit reuse of its inserted toothed disc more than one time, possibly leading to unwanted infections. In the most preferred embodiments of the Needle Carriers used in the present invention the Needle Carriers are mechanically blocked from being casually or accidentally reused, even if the used Needle Carrier Wheel is accidentally reinserted, and, thereby, the opportunity for unwanted infections is reduced. 
         [0030]    U.S. Pat. No. 4,157,086 embodies a knife-type edge to effectuate entrance into a skin surface in a cutting fashion. The present patent application embodies a group of needles which effectuate entrance into a skin surface in a puncturing fashion which is much less intrusive and much less traumatic than the imposition of a cut in the skin. Further, the device in U.S. Pat. No. 4,157,086 embodies only one cutting part, and that part can be repeatedly used. This fact means it can lead to unwanted infections when used on different subjects or at different times. The present patent application embodies a group of needles each of which can be used but once, thereby limiting the possibility of infections. 
       DESCRIPTION OF THE RELATED ART 
       [0031]    There are numerous types of devices made for performing the task the present invention performs. There are single-use devices consisting of nothing more than a needle, sometimes surrounded by a holding device. There are single use, short, pencil-like devices in which a needle is shielded until a time when the needle is released and driven by the action of a spring into a patient&#39;s skin. There are multiple-use devices made in the shape of a large-diameter pencil, and holding a few needles released one at a time from a shielded position and thrust by spring-driven action into a patient&#39;s skin. There are multiple-use devices containing a wheel which carries radially-arranged, shielded needles which can be driven into a person&#39;s skin. 
         [0032]    The inventor of the present invention chose to make his invention one containing a wheel carrying a plurality of radially-arranged needle carriers, each of which can be driven radially by spring action to perform a skin puncturing operation. 
         [0033]    There are at least two similarly-constituted, patented devices, but their components and operations are radically different in nature to the present invention. The only similarities between those other devices and the present invention are the ability to make skin punctures, the use of a cased wheel to carry the puncture-making components, and the use of a spring to project the puncturing components. None of those similarities are now a novelty, nor non-obvious, in the field of lancet devices. There are multitudes of patented needle-equipped lancets. There are at least two patents which use a wheel to carry radially-mounted lancet points. And many lancet patents feature the use of a cocked spring to activate a puncturing needle. 
         [0034]    The present invention contains a number of new concepts which are new, non-obvious, and which were created solely in the mind of the present inventor, thus meeting the criteria for patenting. Those concepts will be shown on the accompanying drawings, and discussed in the text accompanying this patent application. 
         [0035]    The present inventor lists in his utility patent application several representative patents by number and name which he believes a person might wish to investigate for comparisons to the present inventors present invention. However, the present inventor knows of no patented invention which bears a substantial resemblance to the present inventor&#39;s present invention.

       BACKGROUND OF THE INVENTION 
       [0038]    1. Field of the Invention 
         [0039]    The present invention, the Renewable Rotary Skin Lancet, pertains to the class of needle-bearing devices and equipment usable by medical practitioners, persons, and patients for the purpose of puncturing a person&#39;s skin as a means of obtaining droplets of fresh blood to be used in making analytical tests. The present invention provides the equipment and a plurality of renewable puncturing needles whereby such punctures can be made safely and antiseptically a plurality of times by a broad range of users by simply cocking and firing the equipment. Then, when its supply of puncturing needles has been exhausted, a new wheel containing a plurality of new puncturing needles can be exchanged for the used wheel containing the used puncturing needles, and the Renewable Rotary Skin Lancet can continue to safely and antiseptically perform its function time after time. 
         [0040]    2. Description of the Related Art 
         [0041]    [a] See also, herein, the section Cross References to Related Applications, specifically the comparison there between the present invention and previously patented lancets. 
         [0042]    [b] Many previously patented lancet devices are designed so a fresh needle-bearing part must be inserted at the time of each use. There are several problems connected with such systems. The primary problem is that during the course of preparing the skin for puncturing, readying a blood analyzer device, and loading a new needle-bearing part, it is quite easy to remember whether or not a new, antiseptic, unused, needle-bearing part has been inserted in the lancet device. The visual appearance of a used and an unused needle when seen by unassisted eyes is precisely the same. The user of such a device may simply overlook the need to insert a fresh needle-bearing part. This can be hazardous to the person whose skin is being punctured, for the needle point of a used needle can have been, during the course of making a prior puncture, or during an intervening time period, contaminated with microscopic antigens or bacteria, possibly leading to dangerous infections. That hazard could be much greater, and more significant if the lancet device being used is used not only on one person, but on a group of persons, as, for example, in a nursing home where an inordinately-high percentage of the occupants are going to be diabetics. Also, the point of an unprotected needle, during the time it resides in its lancet device between usings, may have been damaged to the extent a hook has actually been formed on the delicate, sharpened point, thereby causing an imperfect puncture, and, quite possibly, a dragging out of live tissue from the puncture site, an injurious action. Additionally, loose needle-bearing parts, as marketed by drug stores, although new and unused, may because of their boxed, unwrapped, continually exposed nature, be subject continually to the foregoing hazards. Further, such needle bearing parts subject the user and/or the assistant to the chance of an accidental puncture before, during, and after the actual intended puncture. Imagine you are the nurse administering to a diabetic hepatitis, AIDS or HIV patient. The very thought scares the present inventor, and situations such as that do occur, regularly. The known existence of such dangers as are named above prompted the present inventor to design the present invention. 
         [0043]    The present invention is designed to eliminate the hazards described just preceding. The needle points used in the present invention are shielded from human touch and physical damage from the time they are manufactured until the time their needle wheel is disposed of, except at the moment of an intended skin puncture. It is true that contamination or blunting of the needle points can have occurred before the needle wheels are sterilely packaged for distribution, but federal authorities may have programs overseeing such manufacturing operations, and it is hoped that in no case would a manufacturer of such products allow such problems to exist in their operations. But once the needle wheel of the present invention is in the hands of a user, it would take a deliberate action to expose a needle point wherein it might be blunted, contaminated, or cause an accidental puncture. 
         [0044]    The present inventor knows of no other lancet device having the safeguards against the preceding, named hazards as are designed into the present invention. 
         [0045]    Even so, the present inventor, personally a diabetic who draws his blood at least four times daily, takes additional precautions against the possibility of sustaining infections at his skin-puncturing sites by disinfecting with rubbing alcohol his skin, any exposed needles, and the exposed parts of the lancet devices where they will touch his skin. Not all patients will be given or will take such precautions, so, in the opinion of the present inventor, it is quite important that the needles used for skin punctures be non-reusable, kept sterile, and not used on a plurality of patients. 
         [0046]    [c] There are presently being marketed several lancet devices best described as throwaways. The present inventor does not know whether any, none, or all of these have received patents. They are ideal for hospitals, doctor&#39;s offices, and phlebotomist laboratories, for they can easily be kept sterile, then used once, and finally discarded. However, for a person needing a lancet device several time daily, the inconvenience of keeping a boxful of these on hand, the extra cost, and the disposal factor weigh heavily in favor of having one lancet device for each patient, provided it embodies a large supply of needles. 
         [0047]    The lancet device for which a patent is being asked for by the present inventor will more ideally suit the needs of a person requiring the continual use of a patent device because of the convenience, sterility, and cost factors. 
         [0048]    [d] There is presently being marketed a lancet device in which six needle-bearing devices are installed. The present inventor is unaware of there being a patent issued for said device, but, on the chance that a patent has been issued, And because it is being used by the general public, and thus it will be a competitive product for other lancet devices, it should be noted here that the present invention differs in almost every respect from said six-needle lancet device. In the opinion of the present inventor that lancet device has at least two shortcomings. First, the device holds only six needles, so, based on four punctures being performed daily, the cartridge is good for only 1½ days. Secondly, there is no fail-safe system to prevent the needles in the cartridge from being used over and over. This could lead to finger infections. It also makes it possible for the same needle to be used on more than one person. Again, the threat of diseases such as hepatitis, AIDS, and HIV infections makes such a prospect quite fearful. 
         [0049]    The present invention can hold many needles, the number depending on the diameter of its needle wheel. The inventor estimates it will be practicable for there to be between 60 and 100 needles in the present invention&#39;s needle wheel. A new needle wheel should last 15 to 25 days when used four times daily. Additionally the present invention has a fail-safe feature, whereby no needle can be reused, even by accident. 
         [0050]    [e] There exists a patent for a multi-needle lancet device which contains several needles, and where together the needles make a skin puncture at the same time. Using this device will likely get blood flowing, but is overly productive for normal use, and it will create several holes in the target skin. It is possible for that device to be used time after time, with the attendant possibility of infections being transmitted. Again, the hepatitis/AIDS/HIV factor must be recognized. 
         [0051]    The present invention safeguards against the reuse of lancet needles. 
         [0052]    [f] There exists a patent for a lancet device which includes several puncturing devices mounted on a wheel. That device uses knife-like cutters to puncture skin. Each cutter can be used time after time to draw blood, but the patient would suffer from overly extensive lacerations, and the chance of infections in the patient from repetitive uses would be objectionable. 
         [0053]    The present invention safeguards against the hazards present in that existing patent&#39;s lancet device. 
         [0054]    [g] There exists patents for lancet devices using a rotating knife-like cutter to puncture skin. Each cutter can be used time after time to draw blood, but the patient would suffer from overly extensive lacerations, and the chance of infections in the patient would be objectionable. 
         [0055]    The present invention safeguards against the hazards present in that existing patent&#39;s lancet device. 
         [0056]    [h] There exists a patent for a lancet device wherein the needle-bearing parts are mounted radially on a wheel. It appears that only six such needles can be installed on a single wheel, and it does not appear that the wheel can be replaced when the needles on it have been used. Said lancet device apparently has other shortcomings. Neither the drawings nor claims for said invention are extensive enough to be certain about what that invention included, and such details as are not shown or explained by the patent papers cannot be considered to exist. Other shortcomings are these: The puncture the device makes is within an indentation in the rim of that device, and this is not conducive to its use on flat skin areas such as are preferred by some patients needing the use of a lancet device; There is no means of adjusting the depth its needles penetrate, and such adjustments are needed for different types of skin; The patent suggests that the needle-carrying parts are to be inserted in the wheel by hand, and this presents the possibility of finger sticks and contamination of the needles; The patent suggests that a used needle can remain with its point hazardously exposed after the lancet has been used, and this can be dangerous; The needles in said device must employ an entirely separate device to pull off protective covers on the tips of the needles in the lancet device, and this can lead to problems such as a lost pulling device, blunting of the fragile needle point during the process, and infection of the needle through the presence of contaminated material in the separate, pulling device; The patented device has protruding parts making it unwieldy in both the hand and in storage; The patented device will not delineate the puncture point when it is used, so the exact point of puncture, if it needs to be squeezed to start the blood flowing, cannot be easily determined, and this may mean additional punctures must be made; The patented device is overly complicated for use by patients having borderline mental or physical abilities, and is thereby not conducive to being used by a broad array of people; The needle-bearing parts of the patented device are not made so that, once used, they cannot be reused; and The patented device does not make use of a secondary needle-centering device, so its needle&#39;s precise location may be questionable and erratic. 
         [0057]    In comparison to the shortcomings of the patented device, the present invention has these attributes and differences: A replaceable needle wheel; A detent system for positively centering its needles at the needle aperture; Needles which are shielded from human touch except when a puncture is intended to occur; Can be used on flat or curved areas of skin; Contains a mechanism for closely adjusting the penetration depth of the needle points; Makes use of factory loaded needle wheels; Does not require the use of a separate device for pulling off protective covers on the needles; Will indent the skin visibly in order to see where a puncture has occurred; Cannot reuse the needles; Some of its needle carriers are made wherein a secondary backup to non-reuse of its needles is built in; Requires fewer steps for its use; Can be successfully used by a greater proportion of the population. 
         [0058]    Additionally, the needle-propulsion system, the wheel rotation system, and the firing mechanism on the patented lancet device all differ greatly from those on the present invention being submitted for patenting. 
       BRIEF SUMMARY OF THE INVENTION 
       [0059]    The Renewable Rotary Skin Lancet is a device designed to allow the puncture of the skin of medical patients for the purpose of safely and antiseptically obtaining small amounts of their blood, usually as a preliminary to using said blood for testing purposes, and to do so with the least practicable amount of danger, discomfort, cost, outside assistance, and effort. 
         [0060]    The Renewable Rotary Skin Lancet is comprised of a mechanism contained in a case which may be easily opened by the user. The mechanism is comprised of a circular wheel containing needle carriers, each of which contains a pointed needle. A mechanism is provided whereby the user may propel the needles on the needle carriers, one by one, into the patient&#39;s skin. A cocking procedure is required after each needle carrier is used, and this cocks the propulsion mechanism while rotating the needle-carrying wheel so that a new, unused, needle is moved into a position where it may be propelled next. After all the new, unused, needles on the wheel have been used one time the needle-carrying wheel can no longer be made to rotate. Then, so the device can continue to be used, the used wheel can be removed, and a new needle-bearing rotary wheel can be inserted into the device, making the device again ready for use. 
         [0061]    The present invention is intended for each of the devices to be used on one person. Even though the chance of cross infection would be small if it were used on more than one person, that possibility should be avoided. The device is designed with the intention that the user is also the person whose blood is being tested, but, of course, an assistant can also make the puncture if that need exists. 
         [0062]    It is the primary objective of the present invention, the Renewable Rotary Skin Lancet, to provide a safe, convenient, and easily used lancet device for obtaining small amounts of blood from a broad array of persons. 
         [0063]    Largely due to the growing prevalence of diabetes across all ages, races, genders and sizes of people, there is a growing need for a lancet device which can be used with safety by a diverse group of persons. People who are young, disabled, incapacitated, or ill may need, irrespective of their limitations, a lancet device which they can personally use without the possibility of accidental blood contamination from unwanted needle punctures, dirty needles. The present invention has needle points which are, with normal use, unable to be touched except at the time of each intended puncture, and, because of this, it stands almost alone in its safe shielding of its plurality of needle points up to and after the time a purposeful skin puncture is made. The present invention promotes the safe use of lancet devices. 
         [0064]    Whereas, after each use of a single-use lancet device, such a device should be disposed of in a sharps container, this is not necessary with the present invention, for, even after a renewable needle wheel has be completely used, the needle points of the throwaway wheel are not exposed to being touched. 
         [0065]    In the event the present invention encounters some possibly-infectious environment, it ordinarily may be sterilized by immersion in an antiseptic mix of alcohol. As an additional precaution, the present inventor recommends using an alcohol pad to wipe and sterilize the needle aperture area of this or any lancet device prior to each use. During normal blood testing there will be an alcohol-soaked pad used in other parts of the testing, and this will be available for fulfilling this extra safety step. 
         [0066]    When the present invention is used in group facilities such as nursing homes or hospitals, it is important that the name of the person to whom the use of the device is consigned be written with an indelible marker directly on the device as a means of segregating the device to the use of only one individual. There is space provided on both sides of the present invention for this to be done. 
         [0067]    The size of the present invention is larger than some other lancets, but it is small enough to fit in the palm of one hand, yet large enough to keep it from being easily misplaced. 
         [0068]    Because there is a plurality of numbered needle carriers in the present invention, its supply of needles will last much longer than other types of lancets, and, at any time, the user can see what quantity of needles remains available for use. Once the present invention is equipped with a new needle carrier wheel, all that remains for putting it to use is pushing the triggering button to fire the device, then cocking the device before the next use. With the exception of some juveniles, the present invention should be able to be used without assistance by all persons having near-normal physical and mental capacities. 
         [0069]    Some other lancet devices have some of the advanced features of the present invention. The present inventor knows of no other lancet device which has all of the advanced features of the present invention. 
         [0070]    Following is a list of some of the problems present in at least one or more other lancet devices. These problems have been solved in the design of the Renewable Rotary Skin Lancet. 
         [0071]    1. The needles in the other device(s) are able to be reused, possibly leading to infections or damaged needle points. 
         [0072]    2. The other device(s) are too cumbersome or their use too involved to be used personally by some persons having reduced capabilities. 
         [0073]    3. The other device(s) incorporate the use of either only one or only a few needles, thus requiring extra time and effort to make the device(s) ready for use. 
         [0074]    4. The other device(s) cut the skin instead of puncturing it, thereby causing an unnecessary, possibly harmful, laceration when obtaining blood samples. 
         [0075]    5. The other device(s) have their needle points exposed for a period of time, other than at the moment of puncture, during the use of the device(s), possibly leading to needle contamination or needle damage. 
         [0076]    6. The other device(s) have their needle points exposed for a period of time during the readying or use of the device(s), possibly resulting in accidental needle punctures and a resulting disease. 
         [0077]    7. The other device(s) incorporate no provision for adjusting the depth of penetration of their needles during a puncturing procedure. 
         [0078]    8. The other device(s) leave a needle point exposed after their use, necessitating, if good sanitation is practiced, the use of a sharps container. 
         [0079]    9. The other device(s) would be subject to damage if they were immersed in rubbing alcohol, making it necessary to throw them away if contamination is suspected. 
         [0080]    10. The other device(s) cannot be marked with the name of the person to whom they are consigned. 
         [0081]    11. The other device(s) require the removal of a protective cover from their needles before they can be used, thereby increasing the time and effort for their use and subjecting the user to a possible unwanted skin puncture while removing the cover. 
         [0082]    12. The other device(s) require the use of a separate, preparatory device in order for the lancet device to be used. 
         [0083]    13. The other device(s) are an unwieldy shape or size, making them awkward to handle and carry, difficult to store, confusing to use, or so small as to be easily misplaced. 
         [0084]    14. The other device(s) do not delineate the point of puncture with a short-lived impression in the skin when a puncture is made, possibly necessitating follow-up punctures if the puncture site should be squeezed but cannot be found. 
         [0085]    15. The other device(s) do not have needle carriers which, once used, will refuse to be propelled for another use, thereby denying the user a backup to any first line of reuse rejection the device may have. 
         [0086]    16. The other device(s) can only be used on a tightly curved area of skin, such as a finger or toe, and this excludes their use by persons seeking to puncture a flatter area of skin, such as an arm or a thigh. 
         [0087]    17. The other device(s), where a plurality of needles is stored in the device, lack a means of quickly determining what quantity of unused needles remain in the device. 
     
     
       IDENTIFICATION AND DESCRIPTION OF THE FIGURES ON THE DRAWINGS FOR THE RENEWABLE ROTARY SKIN LANCET 
         [0088]      FIG. 1  Oblique view of the lid side of the Case for Alternate Device No.  1 . The Case is used to contain the entire working mechanism of the device. The Case serves to minimize the intrusion of unwanted matter in the working mechanism, which must be kept as sterile as possible. There will be three unsealed openings in the case. The Aperture  1 D for the Needle projection. The Opening  1 A for the triggering Pushbutton  5 . And the Opening  1 B for the Cocking Lever  4 G. There will be some projecting parts molded to the inner surface of the Case Lid  2  and the Case Bottom  1 . The Case Lid and the Case Bottom may be made of either some sort of plastic or some sort of metal. 
           [0089]      FIG. 2  Oblique view of the bottom side of the Case for Alternate device No.  1 .

           [0092]      FIG. 5  Plan view of the Lid attachment screws  2 B. These serve to hold the Case Lid on the Case Bottom. It is highly likely that these screws will be replaced in the actual manufacturing process by some sort of fastener which can be operated by the user&#39;s fingers, and there may be a hinge of some sort to keep the Case Lid and Case Bottom attached. The capability of the manufacturer will dictate the fastening used. The screws, if such are used, may be made of some sort of plastic or some sort of metal. 
           [0093]      FIG. 6  Side view of the Lid attachment screws. 
           [0094]      FIG. 7  Section through the perimeter of the lid for the Case of Alternate Device No.  1 . The Offset  2 A in the meeting-edges of both the Case Lid and the Case Bottom merely serve to help keep those two parts firmly attached together in the proper relationship to each other. 
           [0095]      FIG. 8  Plan view of the exterior of the bottom side of the Case for Alternate device No.  1 . 
           [0096]      FIG. 9  Plan view of the interior of the Case Bottom for Alternate Device No.  1 . The Centering Notch  1 E is used to mark the location of Needle-Carrier number  1  when a new Needle-Carrier Wheel is inserted. The Lid-Attachment Screw Posts  1 H are shown, and these serve also as spacers to keep the Case Lid the proper distance from the Case Bottom so the Case Lid does not keep the Needle-Carrier Wheel from rotating freely. The Carrier Alignment Posts  1 G are shown. These fit snugly, but freely, in Alignment-Post Openings  3 S located in the Wheel Carrier  3 , and serve to keep the Wheel Carrier laterally stable while still permitting it to slide towards and away from the Needle Aperture  1 D when the Needle&#39;s penetration depth is being adjusted.

           [0100]      FIG. 13  Plan view of the inside of the Wheel Carrier  3 A for Alternate Device No.  1 . The Wheel Carrier  3  serves as a platform for the working mechanisms of the device. Use of the Wheel Carrier allows the working mechanism to be moved towards or from the Needle Aperture  1 D of the Case, and this makes possible the adjustment of the depth of penetration of the Needle  7 A when it is used for puncturing skin. The Wheel Carrier may be made of some sort of plastic or some sort of metal.

           [0103]      FIG. 16  Face view of the Upper Hammer Guide  3 H showing the Hammer opening  3 L and the Push Button Spring opening  3 J. Both Hammer Guides are essentially the same, but the Upper Hammer Guide contains an opening through which the Pushbutton Spring will pass and be flexed. The Hammer Guides will prevent lateral movement of the Hammer as it is operated. The Hammer Guides will serve as retainers for the cylindrical compression springs  4 A and  4 B surrounding the Hammer. The Hammer Guides will be an integral part of the Wheel Carrier  3 H, and made of the same material

           [0114]      FIG. 27  Longitudinal section of the Renewable Rotary Skin Lancet, Alternate Device No.  1  with parts numbers removed for clarity of drawing details. This version shows the Hammer fired, and the Needle in its puncturing position. 
           [0115]      FIG. 28  Longitudinal section of the Renewable Rotary Skin Lancet, Alternate Device No.  1  with parts numbers removed for clarity of drawing details. This version shows the Hammer as it is being cocked, and with the Needle partly retracted after being used to make a skin puncture. 
           [0116]      FIG. 29  This shows a section through the Wheel  6  of Alternate Device No.  1  with a Needle Carrier  7  in its pre-fired or retracted position. The Wheel contains the Needle Carriers in the Needle Slots  6 B. The Wheel  6  and the Needle Carriers  7  may be made of plastic or metal, and there must be little friction between the Wheel and the Needle Carriers so the Needle Carriers can easily be impelled. The Wheel has a Rubbing Rail  6 A which is perpendicular to the main plane of the Wheel, and this seats over a counterpart  3 R Rubbing Rail on the Wheel Carrier  3  to keep the Wheel  6  properly aligned and smoothly rotational. 
           [0117]      FIG. 30  This shows a section through the Wheel  6  of Alternate Device No.  1  at an Advancer Pit  6 G. The Advancer Pit is a recess into which the Advancer  4 K will be thrust when the Hammer  4  is cocked. The Advancer Pit serves as a sort of cog, and is used to move the Wheel  6  along its rotational path. 
           [0118]      FIG. 31  This shows a section through the Wheel  6  of Alternate Device No.  1  at a Detent Notch  6 E. The Detent Notch is used as a seat for the Detent Protrusion  3 Y. Together, the Detent Notch and Detent Protrusion serve to keep the Needle Carriers centered on the Needle Aperture  1 D. 
           [0119]      FIG. 32  A plan view of the Wheel of Alternate Device No.  1  showing the Stop Post  6 D and the direction of rotation. The Stop Post is an integral projection on the Needle Carrier Wheel  6 . Its counterpart is the Wheel-Stop Tab  3 W which is an integral part of the Wheel Carrier. When a new Wheel  6  is inserted in the device the Stop Post will be on the leading side of the Wheel-Stop Tab. When all the Needle Carriers in the Wheel have be used once, the Stop Post will meet the Wheel Stop Tab, and will then disallow any further rotation of the Wheel, and, thereby, any further use of the now-used Needles. 
           [0120]      FIG. 33  A plan view of internal sections of the Wheel of Alternate Device No.  1  showing the Needle-Carrier Slots  6 B, Detent Notches  6 E, and entry-exit spaces  6 G and  6 H for the Probe when it is in a fired state. The Wheel contains Needle-Carrier Slots  6 B within which the Needle Carriers  7  are located. The Needle Carriers contain the Needles  7 A used for making skin punctures. The Probe Slot for Wheel Insertion  6 G is an entry space in the Wheel used to receive the Probe when it is in a fired state, as it must be so the advancer  4 K will be clear of the Advancer Pits  6 C at the opposite end of the Wheel when a new Wheel is inserted. The Probe Slot for Wheel Removal serves a similar purpose when the used Wheel is removed. 
           [0121]      FIG. 34  Another plan view of internal sections of the Wheel of Alternate Device No.  1  showing the Needle Carrier Slots, Detent Notches, and entry-exit spaces for the Probe when it is in a fired state. 
           [0122]      FIG. 35  A section through one edge of the Alternate Device No.  1  showing the Stop Post, Detent Ramp, and Detent Leaf. The detent Ramp is an integral part of the Wheel Carrier. It serves to elevate the Detent Leaf to a usable height, The Detent Leaf and its Detent Protrusion are one part. The Detent Leaf acts as a spring to keep its Protrusion tightly against the bottom side of the Wheel. The Detent Leaf and its Protrusion  3 Y may be made of either plastic or of metal. 
           [0123]      FIG. 36  A view from its anchoring end of the Detent Leaf and its Protrusion  3 Y of the Alternate Device No.  1 . 
           [0124]      FIG. 37  A view from its anchoring end of the Detent Leaf  3 Y and Detent Ramp  3 X showing a part of the Wheel  6  of the Alternate Device No.  1  in the background. 
           [0125]      FIG. 38  A section through one edge of the Alternate Device No.  1  showing the Stop Post  6 D and Wheel Stop Tab  3 W. 
           [0126]      FIG. 39  A detail at one edge of the Alternate Device No.  1  showing the Stop Post and Wheel Stop Tab after a new Wheel has been inserted, with a part of the Wheel in the background. The wheel is now ready to be used from its first Needle. 
           [0127]      FIG. 40  A plan view of the Detent Leaf and Detent Ramp of the Alternate Device No.  1 . 
           [0128]      FIG. 41A  plan view showing the Stop Post and Wheel Stop Tab of the Alternate Device No.  1  after a new Wheel has been inserted. 
           [0129]      FIG. 42  A plan view of the Wheel of the Alternate Device No.  1  showing the entry and exit spaces in the bottom side of the Wheel to allow insertion and removal of the Wheel at the beginning and end of its use when the Probe and Hammer are in their fired position. Also shown are the numbers  8  on the Wheel indicating the number of the Needle Carrier  7  positioned beneath the number. The numbers, and any other markings, arrows, or instructions are to be of lasting quality, not destructible by any alcohol used for sterilization purposes, and clearly visible on whichever surface they are installed. 
           [0130]      FIG. 43  A section through one edge of the Wheel of Alternate Device No.  1  without any descriptive lettering, shown for clarity of design. 
           [0131]      FIG. 44  A view of the inner perimeter of the Wheel of the Alternate Device No.  1  showing the entry and exit slots for the Probe when the Wheel is being inserted or removed. 
           [0132]      FIG. 45  A section through one edge of Alternate Device No.  1  without any descriptive lettering, shown for clarity of design. 
           [0133]      FIG. 46  A detail at one edge of the Alternate Device No.  1  showing the Stop Post and Wheel Stop Tab after a Wheel has been completely exhausted of new Needles, with a part of the Wheel in the background. The Wheel is ready for replacement. 
           [0134]      FIG. 47  A plan section of the inner perimeter of the Wheel of the Alternate Device No.  1  showing the entry and exit slots for the Probe for use when the Wheel is being inserted or removed. The Hammer must be in a fired position for the Wheel to be successfully inserted or removed. This creates the need for these slots. If the Hammer is not fired, the Advancer would be inside one of its pits, and would restrict insertion or removal of the wheel. If the Hammer is fired, the Probe/Retractor would be inside a Needle Carrier Slot in the Wheel except when the Probe/Retractor is at the designated insertion and removal slots  6  G and  6 H in the Wheel. 
           [0135]      FIG. 48  A plan view at one edge of the Alternate Device No.  1  showing the Stop Post and Wheel Stop Tab after a Wheel has been completely exhausted of new Needles. The Wheel is ready for replacement. 
           [0136]      FIG. 49  The plan view of the Hammer  4  of the Alternate Device No.  1 . The hammer may be made of plastic or metal. Its purpose is to act as a weighted mass which will properly carry the probe/retractor toward a Needle Carrier, strike the Needle Carrier, and impel the Needle Carrier towards the skin of the target person. It must fit snugly but not bound within its Guides, and be nearly without friction so it can travel easily and without lateral deviation along its longitudinal axis. The Hammer may need weight added or subtracted so that it will have the proper balance of momentum and inertia, and coordinated with the springs surrounding it, it will capably perform its intended functions. 
           [0137]      FIG. 50  The left side view of the Hammer of the Alternate Device No.  1 .

           [0140]      FIG. 53  The bottom view of the Hammer of the Alternate Device No.  1 . 
           [0141]      FIG. 54  A side view of the Advancer  4 K of the Alternate Device No.  1  after it has been moved by the Cocking Lever  4 G to advance the Wheel  6  forward one Needle Carrier Space. The Advancer is used to rotate the Wheel. It may be made of either plastic or metal. It is fastened to the Hammer in a way so it can be removed for repair or replacement. The extent of its action is governed by adjustment screw  30  (three-Oh). If there is some malfunction of the operating mechanisms during their use, it may be necessary to remove the Advancer so the Wheel can be removed, for the Probe/Retractor may not be in its Slot for Wheel Removal  6 H at the time of malfunction. The leaf part of the advancer must be flexible, but the degree of flexibility must be finely governed to be sure the Advancer performs properly. There is an angled hump on the Advancer, and the purpose of this is to cant the loose end of the Advancer in the direction of rotation of the Wheel  6 , thereby, with its push on the side wall of an Advancer Pit  6 C, moving the Wheel  6  along its intended path of rotation by the proper distance for bringing a new Needle Carrier into the position in which it can be impelled towards the target&#39;s skin. There will be a tendency for the loose end of the Advancer to drag the Wheel  6  backwards, opposite its intended rotational path, as the Advancer returns to its static position, and the Detent with Protrusion  3 Y is intended to firmly anchor the Wheel once the Wheel has been advanced to place a new Needle Carrier in a usable position. The Protrusion of  3 Y may need to be made with a slope on the following face and a vertical face on the leading face, with a complimentary shape used on the Detent Notches  6 E, to firmly anchor the Wheel  6  when it has reached its proper advancement. If the Detent Leaf  3 Y needs to be more effective, its orientation may need to be revised so any tendency of the leaf part of Detent Leaf  3 Y to twist or crumple will be forestalled.

           [0147]      FIG. 60  A knob end view of the Adjusting Knob  3 D when assembled. This knob is attached to the Wheel Carrier  6  via a Threaded Stud  3 A. Turning the Adjusting Knob moves the Wheel Carrier  3  towards or away from the Needle Aperture, and, thereby, adjusts the depth of the Needle&#39;s skin penetration. The Knob and its associated parts may be made of either plastic or metal. A Washer  3 B will be used to reduce friction. A partially-protruding Pin  3 C may be needed to retain the Washer. Although not shown, a second Washer  3 B may be needed between the Knob  3 D and the case containing the mechanisms. 
           [0148]      FIG. 61A  plan view of the Adjusting Knob parts when assembled. 
           [0149]      FIG. 62  An Adjusting Stud end view of the Adjusting Knob parts when assembled. 
           [0150]      FIG. 63  A section through one edge of the Alternate Device No.  1  showing the use of Alternate Needle Carrier  7  and Alternate Probe  4 E. The Needle is in its puncturing position. Several alternate Needle Carriers and Probe/Retractors designed to function with their companion Needle are shown on the drawings accompanying the application for patenting the present device. The type chosen for actual use will be made when the capabilities of the selected manufacturer is known and the best embodiment of the Renewable Rotary Skin Lancet has been chosen. Although the various Needle Carrier types are shown with cylindrical or oval-sectioned bodies, most of them may be made also of rectangular-sectioned bodies. The present inventor is applying for a patent which includes all of the Needle Carrier types. Needle Carrier  7  includes two flexible Wings  7 B which have at their ends Stop Protrusions  7 C, the purpose of which is to limit the distance the Needle Carrier can travel in its Needle-Carrier Slots  6 B. There are Retraction Protrusions  7 C on the inner surface of the Wings  7 B, the purpose of which is to fit into the Retractor Slot  4 F on Probe/Retractor  4 E, the companion Probe/Retractor for Needle Carrier  7 , when the Probe/Retractor  4 E is thrust into the Needle Carrier, and the Needle Carrier is impelled, and to provide an anchor so the Needle Carrier can be retracted. Once the Probe/Retractor, and connected Needle Carrier have been retracted a certain amount, the Retraction Protrusions  7 C will let the Probe/Retractor continue to withdraw by itself and without the Needle Carrier. The Wings  7 B on the Needle Carrier  7  will be formed in a spread shape, the shape it needs to assume upon retraction, so they will spread out when not bound inside the Needle-Carrier Slot  6 B. 
           [0151]      FIG. 64  A face view of Alternate Needle Carrier Type  7  of the Alternate Device No.  1 . This Needle Carrier, its companion Probe/Retractor  4 E, and all other Needles and their companion Probe Retractors shown in the present patent application may be made of either plastic or metal. The Needles in all those Needle Carriers will be cylindrical rods made of metal, sharply pointed at their protruding end, anchored firmly in the Needle Carrier, and of the smallest diameter consistent with minimal skin damage, but a large enough diameter to withstand bending forces which may normally be present while being used to puncture the target&#39;s skin. Each of the combination of companion Needle Carriers and Probe/Retractors is designed to function together performing their functions of impelling the Needle Carrier to a location where a target&#39;s skin can be punctured, then partially retracting the Needle Carrier while leaving the Needle Carrier in the Wheel within which it resides. Although several of the Needle Carriers are designed so that once they are used a blocking mechanism prevents their reuse, Needle  7  features no such blocking mechanism. However, any reuse would entail a malfunction of some sort, and reuse will, absent such a malfunction, be prevented by the introduction of a new, unused Needle Carrier each time the device&#39;s Hammer is cocked. This should provide the safety factor required, since a malfunction will probably result in the Hammer being unable to be cocked, or no new Needle Carrier being advanced in rotation of the Wheel. This Needle Carrier has no blocking mechanism to provide a second line of defense against its accidental reuse. Nevertheless, its use may be warranted because of its simplicity. 
           [0152]      FIG. 65  A side view of Alternate Needle Carrier  7  of the Alternate Device No.  1 . 
           [0153]      FIG. 66  A section through one edge of the Alternate Device No.  1  showing the use of Alternate Needle Carrier  7  and Alternate Probe Type  4 E. The Needle is shown after its retraction. It would look the same when new and ready to be activated. 
           [0154]      FIG. 67  A face view of Alternate Probe/Retractor  4 E of the Alternate Device No.  1 . The application being made by the present inventor includes several types of Probe/Retractors. This is due to the fact that different needle types require different Probe/Retractors. The purpose of the Probe/Retractors is to strike the Needle Carriers when they are in their proper position to have their Needles impelled into the target&#39;s skin. The Probe/Retractors may be made of plastic or metal. 
           [0155]      FIG. 68  A plan view of Alternate Probe  4 E of the Alternate Device No.  1 . 
           [0156]      FIG. 69  A side view of Alternate Probe  4 E of the Alternate Device No.  1 . 
           [0157]      FIG. 70  A section through one edge of the Alternate Device No.  1  showing the use of Alternate Needle Carrier  9  and Alternate Probe Type  10 . The Needle is in its puncturing position. This Needle Carrier has no blocking mechanism to provide a second line of defense against its accidental reuse. In this version of Needle Carrier/Probe/Retractor, the Needle Carrier is equipped with Jaws  9 C, and the Probe/Retractor  10  includes a cap onto which the Jaws of the Needle Carrier will be clamped in the process of being used. Stop Shoulders  9 B on the Needle Carrier will serve to limit its travel towards the target. The Wings  9 A will be flexible, and will be spread when not bound. Much of what has been said about Needle Carrier  7  and Probe/Retractor  4 E applies also to Needle Carrier  9  and Probe/Retractor  10 .

           [0164]      FIG. 77  A section through one edge of the Alternate Device No.  1  showing the use of Alternate Needle Carrier A 1  and Alternate Probe A 2 . The Needle is shown when new and ready to be activated. 
           [0165]      FIG. 78  A section through one edge of the Alternate Device No.  1  showing the use of Alternate Needle Carrier A 1  and Alternate Probe A 2 . The Needle is shown at the moment it is making a puncture. Alternate Needle Carrier A 1  has been designed with a Shoulder A 6  which is intended to prevent any reuse of this Needle Carrier. When Needle Carrier A 1  is partially retracted after being used, the Shoulder A 6  will be moved outwardly as the Flexible Shoulder Arm A 5  flexes outwardly to its normal shape when it is unrestricted, and Shoulder A 6  will catch on the inner edge of the Wheel if any attempt is made to reuse the Needle Carrier. As with several other Needle Carrier and Probe/Retractor designs, Needle Carrier A 1  and Probe/Retractor A 6  will have deformations on their Caps and Jaws which will make their attachment more secure when they are functioning. 
           [0166]      FIG. 79  A section through one edge of the Alternate Device No.  1  showing the use of Alternate Needle Carrier A 1  and Alternate Probe A 2 . The Needle Carrier and Needle is shown after it has been used for a puncture, after it is released from the Probe/Retractor, before the Probe/Retractor has been completely retracted, and the wings of the Needle Carrier have spread apart, with the wing&#39;s shoulders preventing any reuse of the used Needle Carrier and its Needle. 
           [0167]      FIG. 80  A face view of Alternate Needle Carrier A 1  of the Alternate Device No.  1 . 
           [0168]    This version of the Needle Carrier features two sets of shoulders. The shoulders at the Jaw stops the Needle Carrier from excess travel when those shoulders hit the Wheel after the Hammer has been fired. The shoulders on the Needle Carrier Wing are inside the Needle Carrier Slot before being fired, but are exposed after the Needle Carrier&#39;s retraction, and are then in a position to disallow reuse of the used Needle Carrier and its Needle. 
           [0169]      FIG. 81A  side view of Alternate Needle Carrier A 1  of the Alternate Device No.  1 . 
           [0170]      FIG. 82  A side view of the Cap on Alternate Probe A 2  used with Alternate Needle Carrier A 1  on Alternate Device No.  1 . The Cap surfaces are deformed to better grasp complementary deformations in the Needle Carriers. Such deformations are used on several of the Needle Caps, Needle Jaws, Probe/Retractor Caps, and Probe/Retractor Jaws shown in the present patent application. The deformations are matching grooves and ridges intended to help the caps center on and hold the caps without slipping laterally. 
           [0171]      FIG. 83  A face view of the Cap on Alternate Probe A 2  used with Alternate Needle Carrier A 1  on Alternate Device No.  1 . 
           [0172]      FIG. 84  A view of the beveled end of the Clamping Jaw on Alternate Needle Carrier A 1  used with Alternate Probe/Retractr A 2   0 n Alternate Device No.  1 . The Beveled Ends are intended to make it easier for the Needle Caps or Jaws and the Needle caps or Jaws to meet and slip over each other when their Needle Carriers are being impelled toward the target&#39;s skin. 
           [0173]      FIG. 85  A face view of the beveled end of the Clamping Jaw on Alternate Needle Carrier A 1  used with Alternate Probe/Retractor A 2   0 n Alternate Device No.  1 .

           [0177]      FIG. 89  A section through one edge of the Alternate Device No.  1  showing the use of Alternate Needle Carrier A 11  and Alternate Probe/Retractor A 2 . The Needle Carrier is shown at the moment of making a puncture. 
           [0178]      FIG. 90  A section through one edge of the Alternate Device No.  1  showing the use of Alternate Needle Carrier A 11  and Alternate Probe/Retractor A 2 . The Needle Carrier is shown after having been retracted. The Shoulders A 13  on the Needle Carrier Arms A 12  have dropped into the Shoulder Pockets A 18  formed inside the Needle Carrier Slots within the Wheel, and the Shoulders A 13  then will disallow this Needle Carrier and Needle from reuse.

           [0183]      FIG. 95  A plan view of the Push Button  5  used to release and restrain the Hammers of the Renewable Rotary Skin Lancet. The Pushbutton comprises a rectangular button  5  on which an integral square ring  5 C is formed. The inner dimensions of this ring are somewhat larger than the diameter of the Hammers, for the Hammers must pass through the ring when the Pushbutton is pressed. When the Hammer is cocked the inner edge of the ring will hold the Hammer in its cocked position. The Pushbutton Spring  5 A is a leaf type spring which presses the Pushbutton outwardly from the device Case. When the Hammer is cocked the Pushbutton Spring returns the Pushbutton to its initial position, and the square ring again retains the Hammer. The Pushbutton and Pushbutton Spring are fastened together, and the Pushbutton Spring is fastened to the floor of the Wheel Carrier. The Pushbutton and Pushbutton Spring may be made of Plastic or Metal. This Pushbutton  5  is used whichever of the Alternate Devices is used.

           [0186]      FIG. 98  Oblique view of the lid side of the Case for Alternate Device number  2 . Alternate Device Number  2  is essentially the same as Alternate Device Number  1 , but Alternate Device Number  2  uses a Rocker Arm C 10  and Cog Wheel B 6  method for advancing the Needle-Carrier Wheel B 8 . In this system the Cog Wheel and Needle-Carrier Wheel are two separate wheels bound together only by three Positioning Pins C 11 D. The Positioning Pins are eccentric in location so the Needle Carrier Wheel B 8  can fit only in its correct location on the Cog Wheel B 6 , and, additionally, the Needle Carrier Wheel cannot be installed upside down. The Lancet Number Viewing Window B 3  is located immediately beneath the Needle Aperture  1 D.

           [0219]      FIG. 131  Longitudinal section of the Renewable Rotary Skin Lancet, Alternate Device No.  2  without showing parts numbers. This version also shows the Hammer cocked and ready to fire. This drawing is the same as  FIG. 130 , and is shown again to provide correlation to  FIG. 132  located on the same drawing page. 
           [0220]      FIG. 132  Plan view of interior of Alternate Device No.  2  with the Case Lid removed. In this drawing the function of the Rocker Arm C 10  and Detent C 11  can be seen. The Rocker Arm is activated by the cocking of the Hammer B 4 . But cocking the Hammer does not immediately move the Rocker Arm. The cocking action must first let the Probe/Retractor B 9  grasp the used Needle Carrier B 7  and retract it as far as it is intended to be retracted. This must be done prior to any movement of the Rocker Arm C 10  because, otherwise, the Probe/Retractor may not have had sufficient time to properly retract the used Needle Carrier. Once the Needle Carrier is retracted the Rocker Arm Dog C 10 D must engage a Cog B 6 A in the Cog Wheel B 6  to advance the Cog Wheel, and thereby the Needle Carrier Wheel B 8 , the space of one Needle Carrier. The Elongated Slots C 10 E at the Hammer end of the Rocker Arm will allow the Hammer B 4  to be partly cocked before the Rocker Arm Pin C 10 A reaches the end of the Elongated Holes C 10 E. By that time the proper Needle Carrier retraction must have been completed, and then the Wheel advancement may begin. The purpose of the Detent C 11  is to keep the Wheel B 8  from reversing its rotation once it has been made. The exact length of Elongated Hole C 10 E, the Rocker Arm Axle Pin C 10 C, and the Detent C 11  must be precise for the mechanisms to function as they should. 
           [0221]      FIG. 133  View of the bottom of the Needle Carrier Wheel B 8 . This is the side which will rest against the Cog Wheel B 6  of Alternate Device No.  2 . The Needle Carrier blocking function for Alternate Device Number  2  is contained at each Needle Carrier Channel B 7 G. The blocking parts are integral parts of the Wheel. They are Flaps B 7 F which are pressed out of the way, and encompassing part of the Needle Carrier, when the Needle Carrier is beside them, but fold down, when a Needle Carrier is partly retracted, to the location they had when the Needle Carriers B 7  were not yet in the Needle-Carrier Slots B 7 G. When the Needle Carrier has been partly retracted, the Blocking Flaps, part B 7 F will then be in a position which will block reuse of the used Needle Carrier, and Cover Lips B 7 E will still retain the Needle Carrier in its slot. This Blocking Flaps B 7 F and Cover Lips B 7 E system will lend itself to the Needle Carriers being loaded into the Needle-Carrier Wheel by being pressed in laterally to the Slots B 7 G, rather than longitudinally, probably a more easily conducted procedure. 
           [0222]      FIG. 134  Plan view of a single Needle Carrier of Alternate Device No.  2  in the Needle Carrier Wheel while in the position it would be in after having been used. The Blocking Flaps B 7 F have folded into a position at the Needle end of the Needle Carrier to disallow any further use of this Needle Carrier. The Cover Lips B 7 E will retain the Needle Carrier in its slot in the Wheel until the Needle Carrier Wheel is removed and discarded.

           [0225]      FIG. 137  Plan view of a single Needle Carrier B 7  of Alternate Device No.  2  in the Needle Carrier Wheel B 8  while in the position it would be in before it is used. The Blocking Flaps B 7 F partly cover the Needle Carrier. The Cover Lips B 7 E are also partly covering the Needle Carrier. 
           [0226]      FIG. 138  A view at the Needle end of several of the Needle Carriers of Alternate Device Number  2  before they have been used. One Needle Carrier Slot B 7 G is empty to illustrate the unoccupied position of the Blocking Flaps and Cover Lips. The Blocking Flaps are in a folded-down position in their unoccupied state so they return to that condition when a Needle Carrier is not present.

           [0238]      FIG. 150  A view of the Dog C 11 A end of the Cog Wheel Detent C 11  assembly as used on Alternate Device Number  2 . The Cog Wheel Detent Assembly C 11  has two functions. Primarily it keeps the Cog Wheel B 6  from being dragged in reverse by the action of the Rocker Arm Dog CLOD when the Cocking Lever C 10  is pulled and the Rocker Arm Dog CLOD is moving in reverse against the Cog Wheel surfaces. Additionally, the forcible seating of the Dog of the Cog Wheel Detent Assembly C 11  will help to firmly center and keep centered the new Needle Carrier in the correct position for being struck by the Probe/Retractor.

           [0254]      FIG. 166  A view of the Needle Carrier B 7  and Probe/Retractor B 9  of Alternate Device Number  2  with the Needle Carrier B 7  in position to be used, and the Probe/Retractor B 9  fully retracted and cocked, ready to fire. 
           [0255]      FIG. 167  A view of the Needle Carrier B 7  and Probe/Retractor B 9  of Alternate Device Number  2  with the Needle Carrier B 7  in the position for it to be used, and the Probe/Retractor B 9  is moving towards the Needle Carrier B 7  preparatory to striking it. 
           [0256]      FIG. 168  A view of the Needle Carrier B 7  and Probe/Retractor B 9  of Alternate Device Number  2  with the Needle Carrier having been struck by the Probe/Retractor, moving the Needle Carrier towards the point where it can make a puncture in a person&#39;s skin. 
           [0257]      FIG. 169  A view of the Needle Carrier B 7  and Probe/Retractor B 9  of Alternate Device Number  2  with the Needle Carrier being shown at the moment its Needle makes a puncture. 
           [0258]      FIG. 170  A view of the Needle Carrier B 6  and Probe/Retractor B 9  of Alternate Device Number  2  with the Needle Carrier being partly retracted from its puncturing position. The Needle Carrier should have reached this position under pressure from the Rebound Spring  4 B, which must be selected for that purpose. From this point in the retraction process the retraction will be caused by the manual cocking of the Hammer B 4  by use of the Cocking Lever B 4 B. 
           [0259]      FIG. 171A  view of the Needle Carrier B 6  and Probe/Retractor B 9  of Alternate Device Number  2  with the Needle Carrier having been fully retracted. The Spreader B 3 A has just engaged the flexible arms of the Probe/Retractor B 9 , and will open up the Retractor Jaws B 7 B and the Needle Carrier&#39;s Retractor Cap B 7 B will be released. It is at this point that the Dog CLOD on the Rocker Arm C 10  is to engage a Cog B 6 A in the Cog Wheel B 6 , and by the time the Hammer B 4  is fully recocked the Cog Wheel B 6 , and thereby the attached Needle Carrier Wheel B 7 , should have advanced the space of one Needle position, and a new Needle Carrier should have been moved into the position preparatory to its firing. 
           [0260]      FIG. 172  A view of the Needle Carrier B 7  and Probe/Retractor B 9  of Alternate Device Number  2  with the Needle Carrier now fully released. The Blocking Flaps B 7 F are now engaged to disallow further use of this Needle Carrier. The Probe/Retractor B 9  is still moving under force from the Cocking Lever B 4 B, and will quickly be in a cocked position again. 
           [0261]      FIG. 173  A view of the Needle Carrier B 7  and Probe/Retractor B 9  of Alternate Device Number  2  with a new Needle Carrier now in position to be used, and the Probe/Retractor fully retracted and cocked, ready to fire. 
           [0262]      FIG. 174  A longitudinal section of Alternate Device Number  3  with the various part numbers shown. Many of the parts are the same as those found on Alternate Device Number  1  and Alternate Device Number  2 . The Needle Carriers C 6 , Needle-Carrier Wheel C 8 , Probe Retractor C 7 , and Hammer C 9  all have some minor changes from comparable parts from Alternate Device Number  1  and Alternate Device Number  2 . The changes were made necessary because of the changes in the Needle Carriers, namely, the oval section and Stop Arm C 6 B shapes on Needle Carrier C 6 . 
           [0263]      FIG. 175  This is the same as  FIG. 174 , except that no parts numbers are shown. This is done to enable a clearer vision of the device&#39;s parts. In this view the Hammer C 9  is cocked and the Needle Carrier C 6  is new and ready to be impelled into the target&#39;s skin. 
           [0264]      FIG. 176  Same as  FIG. 175 . Placed alongside  FIG. 177  as an aid in understanding the information in  FIG. 177 . 
           [0265]      FIG. 177  A plan view of Alternate Device Number  3  with its Case Lid B 2  removed. 
           [0266]      FIG. 178  A view of the bottom of the Needle-Carrier Wheel C 8  of Alternative Device Number  3  as seen from the side which will rest against the Cog Wheel B 6 . 
           [0267]      FIG. 179  A view of part of the outer edge of Needle-Carrier Wheel C 8  showing the oval-shaped Needle-Carrier Slots C 8 A. In order for the matching deformations on the Probe/Retractor Jaws and the Needle-Carrier Caps to be kept in alignment, the Needle Carrier must not twist, so the Needle Carriers C 6  and the Needle-Carrier Slots C 8 A are being made in an oval shape. This will preclude twisting of the Needle Carriers as they might do if made cylindrically. However, if there is some advantage in their manufacture if a rectangular section replaces the oval section, that would work as well. Further, the reduced lateral dimension made possible by an oval or rectangular shape will allow more Needle Carriers to be placed in the Wheel than would cylindrical Needle Carriers. The Needle Carriers, whichever type is used in the final production of this device or any of the devices shown in the present invention, are to be made as small in lateral dimension as is possible, consistent with their structural integrity during actual usage, for this will permit the use of the greatest number of Needle Carriers in the present invention. The Stop Arms C 6 B of the Needle Carriers will be formed, when they are manufactured, spread out from the body of the Needle Carrier. These will need to be depressed all the way to the Needle-Carrier C 6  body in order to insert them into the Needle-Carrier Wheel C 8  when the Needle Carriers are being loaded into the Wheel, and they will remain tightly alongside the Needle-Carrier body until such time as they are partially retracted, at which time the Stop Arms C 6 B will spring back to their natural position, Will catch on the Needle-Carrier Wheel&#39;s edge, keeping the Needle Carriers from reentry into their slots, thereby preventing any accidental reuse of the Needle Carrier. The Stop Arms must be made as small as is possible, consistent with their being able to not be crumpled if called on to resist a blow from the Hammer. All of these parts may be made of plastic or metal. 
           [0268]      FIG. 180  This shows a section through one of the oval Needle Carriers C 6  of Alternative Device Number  3  while it is in a firing position inside its Needle-Carrier Wheel C 8 . 
           [0269]      FIG. 181  In this view the Hammer C 9  and Probe/Retractor C 7  of Alternative Device Number  3  are cocked and ready to be fired. A new Needle Carrier C 6  is in the proper position to be propelled into a target&#39;s skin by the Probe/Retractor C 7 . 
           [0270]      FIG. 182  In this view the Hammer C 9  of Alternative Device Number  3  has been released by the Pushbutton  5  and the Probe/Retractor Jaws C 7 C have bumped the Cap C 6 E of the Needle Carrier C 6 . The Jaws have slid over the Cap, moving it a bit. Now the Shoulders of the Jaws will strike the Cap and move the Needle C 6 A toward the target&#39;s skin. 
           [0271]      FIG. 183  In this view of Alternative Device Number  3  the Jaws C 7 C have completely clamped onto the Cap C 6 E of the Needle Carrier C 6 , and the Needle Carrier is well on its way to making a puncture in the target&#39;s skin, if any is present. 
           [0272]      FIG. 184  This is a view of the Alternate Device Number  3  at the moment its Needle C 6 A is making a puncture. The Hammer B 4  has been stopped by the Spreader Bar B 3 A. The Needle Carrier has been stopped by its rim C 6 C, which has met the Needle-Carrier Wheel&#39;s C 8  inner edge. 
           [0273]      FIG. 185  This is a view of the Alternate Device Number  3  at the time the Jaws are pulling the Needle Carrier back from a puncturing position, and the spreader bar has just met the Probe/Retractor Arms C 7 B which are about to be spread so the Jaws can release the Needle-Carrier Cap, thus completing the retraction of the used Needle Carrier. Immediately thereafter the Rocker Arm C 10  will, during the remainder of the travel left in the Rocker Arm, engage the striking side of a Cog B 6 D and will advance the Needle-Carrier Wheel to position a new Needle Carrier to a usable location. 
           [0274]      FIG. 186  In this view the Needle Carrier C 6  has been retracted far enough so two wings C 6 B on the Needle Carrier have popped out from the Needle-Carrier body. These Wings will keep the used Needle Carrier from being accidentally reused. In actual practice momentum may have carried the Needle Carrier a bit further, but it will remain in its slot, and cannot be used again. The Rocker Arm is just now beginning to rotate the Needle-Carrier Wheel. 
           [0275]      FIG. 187  This view concludes the series of drawings showing Needle-Carrier movement from start to finish. Here, a new, unused Needle-Carrier C 6  has been moved into position, ready to be impelled. The Hammer C 9  has been cocked and is ready for firing. 
           [0276]      FIG. 188  A face view of Needle Carrier C 6  for use in Alternate Device Number  3 . The Stop Arms C 6 B, Needle C 6 A, Stop Rim C 6 C, Cap Connector C 6 D, and Cap C 6 E are shown. Because of the shape of the Stop Arms an oval-sectioned body will work best for this Needle Carrier. The Cap is deformed to fit complementary deformations in the Jaws C 7 C of Probe/Retractor C 7  used with this Needle Carrier.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0293]    Referring to  FIGS. 1-204  on the drawings detailing the RENEWABLE ROTARY SKIN LANCET, there are three different but quite similar devices shown, also an array of several different Needle Carrier and Probe/Retractor combinations are shown. It may be that more than one of these different devices will become preferred embodiments, or that a combination of the parts shown for more than one of the devices will be combined to make preferred embodiments of the present invention, for the preferred embodiment cannot be known until prototypes of the present invention are constructed and tested. Additionally, the preferred embodiment may be chosen depending on the manufacturing capabilities of the company selected to manufacture the device for marketing. 
         [0294]    Nevertheless, each of the three different devices has the following characteristics in common with each other, making essentially the same device. 
       1. A case comprised of a lid and a bottom fastened together securely, and containing the mechanisms to puncture on demand a person&#39;s skin in order to obtain a small amount of blood for testing purposes. 
     2. An aperture in said case through which a needle may be projected into a person&#39;s skin. 
     3. A viewing window in said case, said viewing window to be equipped with an integral magnifying lens to more clearly make visible the numbers inside said case. 
     4. Numbers on the mechanism inside said case for indicating through said viewing window the number of the needle then positioned in said mechanism for being propelled into a person&#39;s skin. 
     5. A pushbutton projecting through said case to act as a trigger for initiating the propulsion or firing of said needle into a person&#39;s skin. 
     6. A cocking lever projecting through said case to cock said mechanism after each propulsion or firing of said needle. 
     7. A renewable, replaceable needle wheel in the mechanism, said wheel to contain a plurality of radially-positioned needle carriers. 
       [0295]    8. A plurality of said needle carriers, each movable outwardly with restrictions to contain them in their slots and to keep them from, being propelled too far, and each bearing a needle made for the purpose of puncturing a person&#39;s skin. The shape of said needle carriers is to be complementary to the shape of the Probe/Retractors which are used to strike, propel, and retract said needle carriers. 
       9. A cylindrical hammer moving longitudinally within guides towards and then away from said needle aperture. 
     10. A main spring used to propel said hammer towards said needle aperture. 
     11. A rebound spring used to partially retract said hammer and needle carriers after they have been propelled towards a person&#39;s skin. 
     12. A sliding wheel carrier to which the mechanisms inside said case may be fastened and together moved closer to or further from said needle aperture. 
       [0296]    13. A plurality of small bumps or rounded protrusions on the bottom of said wheel carrier for the purpose of reducing the friction between the bottom of said wheel carrier and the inner face of said case bottom when said wheel carrier is being moved for the purpose of adjusting the depth of penetration of said needles. 
       14. Protrusions from said case bottom which snugly, but not tightly, pass through said wheel carrier and keep said wheel carrier aligned laterally so it can slide only directly towards or directly from said needle aperture. 
       [0297]    15. A turnable knob projecting from said case, the knob being used to move said sliding wheel carrier in gradual increments of distance towards and away from said needle aperture, thus adjusting the depth of penetration when a person&#39;s skin is punctured. 
       16. Protrusions on said wheel carrier for the purpose of limiting the distance said hammer can travel both towards and away from said needle aperture. 
     17. A mechanism within said case for advancing, after each firing of said hammer, the said wheel carrier in a rotational manner the distance required to move an unused needle carrier into a proper position for it to be propelled into a person&#39;s skin. 
     18. A mechanism built onto each of the said wheel carriers to prevent said needle wheel from rotating in a direction opposite the intended rotational direction. 
       [0298]    19. Areas or protrusions on the inner, bottom side of said case lid to be used to meet the upper side of said needle wheel in order to closely govern unwanted vertical movement of said needle wheel, this being done to assure proper centering of a said needles in said needle aperture
 
20. A probe/retractor attached to said hammer, and moving in conjunction with said hammer, used to strike said needle carriers as a means of propelling their needles into a person&#39;s skin, and, after that is accomplished, used to retract said needle to a place where it will not be exposed to accidental skin puncturing.
 
       21. A means of positively stopping any further rotation of said needle wheel after its last unused needle carrier has been used. 
     22. Slots, tunnels or grooves in said needle wheel into which said needle carriers can be inserted so that said needle carriers may freely slide within said needle wheel without adverse lateral movement. 
     23. The necessary provisions within said mechanisms whereby said needle wheel can be easily and correctly positioned when a new needle wheel is inserted into the mechanisms. 
       [0299]    The three different devices are shown and referred to in the present invention as Alternate Device Number  1 , Alternate Device Number  2 , and Alternate Device Number  3 . The extent and nature of said differences can be visualized on the drawings which accompany the present patent application. 
         [0300]    The Needle-Carrier Wheel differs in each of the said devices. The Needle Carrier Wheel for Alternate Device Number  1  contains the Advancer Pits which are used in rotating said Wheel, while Alternate Device Number  2  and Alternate Device Number  3  have Needle Carrier Wheels which fit atop separate wheels known as Cog Wheels. The Cogs in the Cog Wheels are used in rotating those Needle Carrier Wheels. These differences are necessitated by the different means of advancing the Needle Carrier Wheel on its rotational path. 
         [0301]    Each of the different Needle Carrier Wheels is equipped with a different type of slot, channel, or groove for containing said Needle Carriers. These differences are necessitated by the different shapes of the various Needle Carriers. 
         [0302]    Several different combinations of Needle Carriers and Probe/Retractors are shown on the said drawing. These are able to be used, perhaps with moderate revisions, on the various Alternate Devices. 
         [0303]    Alternate Device Number One uses a sort of flexible, cam-equipped finger, reaching into an Advancer Pit to rotate the Needle-Carrier Wheel when the Hammer of that device is fired. 
         [0304]    Alternate Devices Number  2  and  3  use a Rocker Arm. Said Rocker Arm is necessitated because the change in design of said Needle-Carrier Wheels is necessitated by the use of different types of Needle Carriers. The Dog end of the Rocker Arm slips into a Cog in said Cog Wheel to provide rotation, while said Rocker Arm&#39;s opposite end is attached to said hammer. When said Hammer is cocked, said Dog end rotates said Cog Wheel, and, thereby, said Needle-Carrier Wheel. Upon the firing of said Hammer, cocking of said Hammer must take place before the device can be used again, and the Dog end then moves a new Needle Carrier into a firing position. Said Rocker Arm is attached to said Hammer via slotted holes. The slotted holes allow said Hammer, during the first part of its travel while being cocked, to retract the used Needle Carrier without starting to rotate the Needle-Carrier Wheel. During the last part of said Hammer&#39;s travel upon being cocked, the pin at the slotted holes alongside the Hammer will finally engage the end of the slotted holes and only then will the rotation of the Needle-Carrier Wheel be started. Said slotted holes are the key element in this dual function of said Rocker Arm.
