       [0002]    Not Applicable. 
       BACKGROUND OF THE INVENTION 
       [0003]    (1) Field of the Invention 
         [0004]    The present invention relates to a treating apparatus and, more particularly, to a treating apparatus which is adapted to a wide variety of uses including those relating to a person&#39;s health. 
         [0005]    (2) Description of the Prior Art 
         [0006]    Medical technology has advanced at an ever increasing rate over many decades. These advances cover a broad spectrum of specific technologies. Simultaneously, otherwise unrelated technologies have also advanced at a rapid pace. While the foregoing advances have, in many cases, been not less than miraculous, there are many areas in which this technology has not been applied, or is otherwise lagging in development. 
         [0007]    There has been a lack of recognition of the uses to which these technologies could be directed, or of the benefits to be derived therefrom. For example, very little progress has been accomplished where communicable diseases may exist in public environments. This is particularly the case where a great number of people may be placed in close contact, have contact with suspected contaminated areas, substances or the like. Such public environments exist, for example, in public transportation, restaurants, city streets, on commercial aircraft, in theaters, at sports events, or any other large gatherings of people, or by exposure to people who may have a higher possibility of being infected, such as in doctor&#39;s offices, hospitals and other health care facilities. 
         [0008]    Conventional practice in such areas of exposure is most frequently to take no precautions whatsoever. In a small number of cases, people may wear surgical masks, or similar facial coverings, for the purpose of limiting such exposure. Such measures are largely self-defeating for numerous reasons. Only a few such reasons need be mentioned to illustrate the point. Surgical masks are porous so that contaminants can pass in both directions therethrough. To the extent they capture contaminants, the contaminants are actually retained in the optimum position to cause exposure; that is, covering the nose and mouth of the person wearing the mask. They are not sealed around the edges so they provide no protection whatsoever to the passage of contaminants around the edges of the masks. Further, such masks are frequently reused with all of the attendant contamination associated therewith. 
         [0009]    In short, no remotely adequate method, or apparatus, is conventionally available for avoiding the direct spread of communicable diseases by such exposure. 
         [0010]    The lack of utilizing technology to full advantage is also illustrated by another example. Monitoring people&#39;s health from remote locations has not utilized technology. For example, medication is usually prescribed for a person, based upon the results of the persons last in office medical examination. The results of the examination direct the attending physician to prescribe those medications which appear indicated. There is no provision available to deal with sudden changes in the physical condition of the patient. Without attention, people otherwise under a doctor&#39;s care can have life threatening events with no adequate possibility of prompt treatment, or, for that matter, the doctor even being aware of the event. As a consequence, needless injury, or death, is well within the realm of possibility. 
         [0011]    Still another example of the lack of the application of technology to the solution of existing problems relates to a persons vital signs. The pulse rate, heart rate and substantially more vital information is not available, as a practical matter, either to the person, doctor, or other health care workers because these vital signs are usually only taken during an in office doctor&#39;s appointment, or at the time of some type of medical emergency. Continuous monitoring of such information is largely unknown. As a consequence, serious injury or death may unnecessarily transpire. Regret frequently takes the form of wishing that the event could have been anticipated and medical personnel intervened to attempt to avoid the result. 
         [0012]    Therefore, it has long been known that it would be desirable to have a treating apparatus which provides protection against the spread of communicable diseases and the like; which is unobtrusive when worn by a person and yet which operates reliably and with an effectiveness not heretofore achieved in the art; which affords a flexibility of use allowing it to be tailored for the specific needs of the subject; which affords a broad range of benefits in use and yet which possesses a simplicity and adaptability in use; which is fully operational in a variety of embodiments; and which is otherwise entirely successful in achieving its operational objectives. 
       BRIEF SUMMARY OF THE INVENTION 
       [0013]    Therefore, it is an object of the present invention to provide an improved treating apparatus.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0034]    Referring more particularly to the drawings, the apparatus of the first embodiment of the present invention generally indicated by the numeral  10  in  FIG. 1 . 
         [0035]    A plurality of embodiments of the treating apparatus  10  are shown and described herein. These embodiments are illustrative of a multiplicity of embodiments which are encompassed by the method and apparatus of the present invention. Since the embodiments shown and described herein have in some cases the same elements, for illustrative convenience the first embodiment of the apparatus of the present invention is first described herein. The first embodiment of the invention is similar to the subsequent embodiments in many respects; that is, those subsequent embodiments of the invention possess operational elements of various forms in addition to the general structure of the first embodiment of the invention. 
       First Embodiment 
       [0036]    The first embodiment of the treating apparatus of the present invention is shown in  FIGS. 1 ,  2 ,  3 ,  4 ,  5 ,  6  and  7 . Referring first to  FIG. 1 , the treating apparatus  10  is shown in a typical operative environment being worn by a person  20 . For future reference and illustrative convenience, it will be understood that the person has bodily portions including a head  21 , eyes  22 , a nose  23  and a mouth  24 . The person has ears  25  and a neck  26 . Again, for illustrative convenience, insofar as clothing is concerned having any relationship to the invention hereof, the person is shown wearing a shirt  27 , pants  28  and a belt  29 . 
         [0037]    The treating apparatus  10  has a dispensing assembly or housing generally indicated by the numeral  40  in  FIG. 1  and which is shown additionally in  FIGS. 2 ,  3 ,  4  and  5 . The dispensing assembly, as will be seen, can be manufactured in a variety of different forms. The dispensing assembly shown and described herein, however, is believed to have operative benefits, as will hereinafter be discussed in greater detail. 
         [0038]    Referring more specifically to  FIG. 4 , the dispensing assembly  40  has a main housing  41  which, itself, has rectangular front wall  42  mounting four rectangularly related sidewalls  43 . The front wall and four sidewalls define an interior chamber  44  therewithin. The main housing mounts a backwall  45  which thereby encapsulates the interior chamber. A pump assembly  50  is mounted within the interior chamber  44 . The pump assembly can be of any suitable type having a power source, not shown. In the preferred embodiment, the pump is operable to pump an airborne substance, as will hereinafter be discussed in greater detail. The pump assembly has a pump housing  51  which mounts a discharge conduit  52  which extends upwardly from the pump housing. The discharge conduit terminates in an orifice  53  which also faces upwardly, as shown in  FIG. 4 . As noted, the pump assembly  50  is of any suitable type operable to release small quantities of a given airborne liquid when activated by a control system, not shown. The pump assembly can be operable to release such liquid, for example, in a continuous flow, or for given periods of time, or in pulses, or in any other manner desired. 
         [0039]    Referring more particularly to  FIGS. 4 and 5 , the dispensing assembly  40  has an intake mechanism  60  having an intake head  61 . The intake head is mounted for pivotal movement on an intake head mount  62  about a pivot pin  63  extending therebetween. Thus, the intake head  61  is mounted for pivotal movement between a lowered position, shown in  FIGS. 4 and 5 , and a position pivotally elevated therefrom. The intake head has a lower surface  64  which faces downwardly in normal use, as shown in  FIG. 5 . The lower surface of the intake head has a transfer coupling  65  mounted thereon. The transfer coupling is generally concave in shape and has a seat  66  therein. A small substantially pin size conduit  67  extends through the intake head  61  from the seat, through the upper end wall  43  of the main housing  41  and into fluid supplying relation to the interior of the pump housing  51 . 
         [0040]    A discharge orifice  80  extends through the upper wall  43  of the main housing  41  in alignment with the orifice  53  of the discharge conduit  52  of the pump assembly  50 . A flexible discharge conduit  81 , having a proximal end portion  82  and a distal end portion  83 , is mounted in and extends through the discharge orifice  80  and into the orifice  53  of the discharge conduit  52  in fluid transferring relation. 
         [0041]    A mounting shaft  90  is mounted on and extends outwardly from the front wall  42  of the main housing  41  in substantially right angular relation thereto, as shown in  FIG. 4 . A fluid selection assembly  100  is mounted for rotational movement on the mounting shaft  90  of the main housing  41  for rotational movement about the mounting shaft. More specifically, the fluid selection assembly has a fluid carousel or wheel  101 , shown in  FIG. 4  in an exploded view, which is mounted for rotational movement on the mounting shaft. The wheel has a frame  102  which itself has a cylindrical ring  103 . The cylindrical ring has cross members  104  which are mounted on the cylindrical ring and extend inwardly to a central hub  105 . The central hub is mounted for rotational movement on the mounting shaft  90 . 
         [0042]    Four internally screwthreaded bores  106  extend through the cylindrical ring in spaced relation to each other, as shown in  FIG. 4 , about the cylindrical ring. Four nozzles  107  are individually mounted in the in the internally screwthreaded bores. Each nozzle communicates in operational relation to a quadrant chamber  108 . A fluid receptacle  109  is mounted in each of the quadrant chambers in operable communication with its respective nozzle  107 . An end plate  110  is mounted on and thereby forms an outer wall of the fluid wheel  101 . Each of the nozzles is covered by a removable cap  111  so that each fluid receptacle is sealed until ready for use, as will hereinafter be discussed in greater detail. 
         [0043]    An attachment clip  120  is mounted on the backwall  45  of the main housing  41 , as best shown in  FIG. 3 . The clip is employed removably to mount the main housing conveniently on the pants  28 , or belt  29 , or in any other convenient location for the person, as best shown in  FIG. 1 . 
         [0044]    As also best shown in  FIG. 1 , the first embodiment of the subject invention has a main supply conduit  130 . The main supply conduit has a first end portion  131  which is mounted in fluid receiving relation on the distal end portion  83  of the flexible discharge conduit. The main supply conduit has a second end portion  132  which is, perhaps, shown best in  FIGS. 1 and 6 . Intermediate the first end portion and the second end portion of the main supply conduit is a back segment  133 . The main back segment preferably extends from the distal end portion  83  of the flexible discharge conduit  81  beneath the shirt  27  and up the back  36  of the person  20 . The flexible discharge conduit  81  and main supply conduit  130  are thereby substantially concealed beneath the shirt of the person. 
         [0045]    The main supply conduit  130  has a neck portion  140  which, in use, is adjacent to the neck of the person  20 ; an ear loop portion  141  which, in use, extends over the adjacent ear  25 , as shown in  FIG. 1 ; and a facial portion  142  which, in use, is extended along the face of the user and beneath the nose  23  of the person. A discharge nozzle assembly  143  is mounted on the terminal end of the facial portion beneath the nose. The discharge nozzle assembly has an adjustable dial  144  which can be turned, or rotated, to position a discharge aperture  145  thereof so as to face in a desired direction. As will subsequently be discussed in greater detail, the desired direction will usually be toward or away from the nose and mouth of the person depending upon the circumstances at hand. An ear loop flange  146  is mounted on the main supply conduit just beneath the ear loop portion, as best shown in  FIGS. 6 and 7 . The ear loop flange is shaped and positioned to engage the underside of the ear fitted therein to help support the ear loop in the correct location and attitude, as shown in  FIG. 1 . 
       Second Embodiment 
       [0046]    The second embodiment of the subject invention is shown in  FIG. 9  and, as heretofore noted, is similar to the first embodiment of the subject invention in that it possesses all of the elements heretofore described with respect to the first embodiment with the exceptions hereinafter noted. 
         [0047]    The discharge nozzle assembly  143  of the first embodiment is different from that of the second embodiment with respect to the specific form thereof. The discharge nozzle assembly  153  of the second embodiment has a V-shaped nose portion  154  shown in  FIG. 8 . As shown therein, the V-shaped nose portion has an aperture  155  at the apex of the V-shaped nose portion through which liquid medication of the like is discharged during operation. 
         [0048]    For illustrative convenience, unless otherwise noted those portions of the second embodiment which are the same as in the first embodiment  10  are described herein only as believed necessary and helpful to a full understanding of the second embodiment. Except as otherwise noted it will be understood that the structure and operation are the same. Accordingly, the main supply conduit  130  is connected in fluid supplying relation to the V-shaped nose portion  154  of the discharge nozzle assembly  153 . The V-shaped nose portion is pivoted on the main supply conduit to permit the aperture  155  thereof to be positioned, as in the first embodiment  10  so that the direction of fluid release can be projected toward the nose  23  of the person  20  or outwardly in the opposite direction away from the person&#39;s nose  23  and mouth  24 . The main supply conduit in the second embodiment has a neck portion  140 , and ear loop portion  141  and a facial portion  142  which are used as in the first embodiment  10  and heretofore described. The first end portion  131  or the main supply conduit  130  is connected to the distal end portion  83  of the flexible discharge conduit  81  in fluid receiving relation. Thus, the second embodiment appears in use roughly as in the case of the first embodiment as shown in  FIG. 1 . Except as otherwise will be noted, the dispensing assembly  40  of the second embodiment is the same as that of the first embodiment, such as shown in  FIGS. 2 ,  3 ,  4  and  5 . 
         [0049]    The second embodiment of the present invention  152  has a laser light assembly generally indicated by the numeral  170  in  FIG. 8 . The laser light assembly is mounted on and extends between the arms of the V-shaped nose portion. Except as hereinafter discussed, the laser light assembly need not be described in greater detail because of its well-known structure and operation in the art. 
         [0050]    With reference again to  FIG. 9 , the second embodiment of the present invention  152  has a thermometer or temperature gauge  180  which is received in the ear  25  of the person  20 . The temperature gauge is held in place in the person&#39;s ear in the conventional fashion. The temperature gauge can be taped over to assist in holding it in place if desired. 
         [0051]    The second embodiment of the present invention  152  has a pulse monitor  190  mounted on the back of the ear  25  of the person. The pulse monitor is operable to detect the pulse of the person and can adhesively be held in place. 
         [0052]    The second embodiment  152  has a heart monitor  200  which is attached to the skin such as by a suitable adhesive, on the chest of the person  20  over his heart. The heart monitor is operable to detect the condition and operation of the heart of the person. 
         [0053]    The second embodiment  152  has a back monitor  210  which is attached to the skin by a suitable adhesive. The back monitor is operable to detect the condition and operation of the back such as by registering, as it is designed to do, for example, muscle spasms, electrical impulses and the like. 
         [0054]    The laser light assembly  170 , temperature gauge  180 , pulse monitor  190 , heart monitor  200  and back monitor  210  are operably interconnected by an electrical system  220  which supplies electrical energy to the various monitors heretofore setforth and which records the information received from those monitors. For this purpose, the electrical system has an electrical conduit  221  operably interconnecting the monitors and a control system  222 . 
         [0055]    The control system  222  is preferably, although not necessarily, housed in the interior chamber  44  of the main housing  41  of the dispensing assembly  40  with the electrical conduit  221  connected thereto. The control system can either or both record the information received for subsequent downloading, or can contain a transmitter instantaneously to transmit the information to a receiver located in, for example, a doctor&#39;s office, hospital, or other medical care facility for use. The control system has a source electrical energy, not shown, for operation thereof. 
       Third Embodiment 
       [0056]    The third embodiment of the subject invention is generally indicated by the numeral  300  and is shown in  FIG. 10 . The third embodiment possesses the same elements as the first embodiment of the invention heretofore setforth. For illustrative convenience, it will be understood that the third embodiment also possesses the discharge nozzle assembly  153  and the pulse monitor  190  of the second embodiment of the invention  152 . 
         [0057]    Turning then, more specifically, to the differences between the third embodiment  10  and second embodiment  152 , the primary distinction in the form shown in  FIG. 9  is that it has a cellular telephone  301 . The cellular telephone has an earpiece with in use us inserted into the ear  25  of the person  20  for use in a manner similar to a normal cellular telephone except as will subsequently be described herein in greater detail. The electrical conduit  221  of the electrical system  220  operatively interconnects the laser light assembly  170 , the cellular telephone, the pulse monitor  190  and the control system  222  for operation as will hereinafter be described in greater detail. 
       Operation 
       [0058]    The operation of the described embodiments of the present invention are believed to be readily apparent and is briefly summarized at this point. 
         [0059]    As in the case of the structure of the first, second and third embodiments of the present invention, the operation of these embodiments is the same for closely similar and various respects. Accordingly, a description of such operation is hereinafter described in summary form. 
         [0060]    It will first be understood that the embodiments of the invention, or portions thereof can be used in various combinations as heretofore described and is believed to be readily apparent. 
         [0061]    In the case of the first embodiment  10  of the subject invention, shown in  FIGS. 1 ,  2 ,  3 ,  4 ,  5 ,  6 ,  7  and  8 , the person  20  decides whether his personal health condition, or that of the other people with whom he may come into contact present a risk of exposure by either to a communicable unhealthful condition such, for example, as influenza. Where such a possibility exists, the person will choose to wear the treating apparatus of the first, second, or third embodiments as the situation warrants. 
         [0062]    In the case of the first embodiment  10 , the dispensing assembly  40  is attached, for example, to the belt  29 , the interconnected flexible discharge conduit  81  and main supply conduit  130  are extended, preferably beneath the shirt  27  and upwardly against the neck  26 . The ear loop portion  141  of the main supply conduit  130  is extended about, and thereby mounted on, the ear  25 . The facial portion  142  is extended across the face of the person  20 , as shown in  FIG. 1  to position the discharge nozzle assembly  143  between the nose  23  and mouth  24 , as shown in  FIG. 1 . If the person believes there is a risk of exposure to a communicable disease from others, the aperture  145  of the discharge assembly  143  is positioned so as to be directed outwardly, or away, from the person&#39;s face. If the person believes he may have communicable disease, he places the aperture to be directed toward his face including nose and mouth. 
         [0063]    Subsequently, the person  20  operates the dispensing assembly  40  using the fluid wheel  101  to position the desired fluid receptacle  109  into snap-fitted engagement with the seat  66  of the intake head  61 . As best shown in  FIG. 5 , the selected nozzle  107  is thereby disposed in fluid supplying relation to the pin size diameter conduit  67  for extraction of the fluid from the fluid receptacle by the pump assembly  50 . 
         [0064]    Each of the fluid receptacles  109  can contain any appropriate fluid such as, for example, air, a disinfectant, vitamins, antibacterial fluids, oxygen, insect repellants, water, or a medicine appropriate to treat the particular communicable disease, condition, or the like. Each fluid receptacle  109  can contain the same fluid or a fluid different form each of the other fluid receptacles. Thus, there is a significant flexibility of usage whereby the same or different fluids can be employed in any order and for any desired length of time. 
         [0065]    Similarly, the pump assembly  50  can be programmed and/or operated to release a continuous spray, mist, or other dispersed configuration of the fluid from the aperture  145 . Alternatively, the fluid can be released in pulses, or for limited periods of time, or any other mode of operation desired. 
         [0066]    The dispersal of the mist away from the face of the user operates substantially to limit the user from being directly exposed to a communicable disease. The mist intercepts contaminated substances such as vapor, dust and other forms of contaminates so that they do not reach the user and communication is avoided. 
         [0067]    All of the preferred embodiments of the subject invention possess the foregoing method and apparatus, although this is not required necessarily for all embodiments of the invention. However, both the second embodiment  152  and third embodiment  300  employ this method and apparatus as shown and described. 
         [0068]    The second embodiment  152 , best shown in  FIGS. 8 and 9 , employs additional systems as hereinafter setforth. The laser light assembly  170  emits light as the person breathes thereon. There is some recognition that laser light, which bounces back and forth multiple times, strikes the molecules contained in the breath. Spectrometry analysis show which frequencies of light were absorbed which, in turn, is an indirect measure of what molecules are in the sample. This information can be used then to detect evidence indicating the presence, for example, of cancer, asthma, diabetes, kidney malfunction and perhaps other diseases and conditions. It has been reported that experiments at the University of Colorado are being conducted on the use of laser light to test for such conditions. The laser light assembly  170  of the second embodiment of the present invention allows this analysis to be done during normal activities. 
         [0069]    The second embodiment  152 , as shown in  FIG. 9  possesses additional health related benefits which may be characterized as including thermometer or temperature gauge  130  in the ear; the pulse monitor  190  behind the ear; and the heart monitor  210 . Other types of monitors can be added, if desired, to those already included. The read out of the collected data is sent by way of the electrical system  220  and electrical conduit  221  to the control system. 
         [0070]    As previously noted, this data can be stored in the control system for subsequent downloading. Alternatively and preferably, the data can immediately be transmitted by a suitable transmitter, not shown, to a designated monitoring location such as a doctor&#39;s office, hospital or other health care facility for prompt evaluation. The optimum and most practical mode of operation depends upon the physical condition of the person and the benefit of having immediate analysis of the data. 
         [0071]    The third embodiment  300  of the subject invention is best shown in  FIGS. 8 and 10 . As previously discussed, the third embodiment of the subject invention may have all or any of the systems and elements of the first embodiment  152 . Some portions thereof are shown in  FIGS. 8 and 10 . However, in the third embodiment the treating apparatus has a cellular telephone  301  placed in the ear and held in place using the earpiece  302 . The presence of the cellular telephone in the third embodiment allows the person to telephone a suitable authority for assistance when an emergency occurs. Such authorities can, of course, be calling “911”, his doctor, a hospital or the like. 
         [0072]    Therefore, the apparatus of the present invention is particularly well suited to use as a treating apparatus which provides protection against the spread of communicable diseases and the like; which is unobtrusive when worn by a person and yet which operates reliably and with an effectiveness not heretofore achieved in the art; which affords a flexibility of use allowing it to be tailored for the specific needs of the subject; which affords a broad range of benefits in use and yet which possesses a simplicity and adaptability in use; which is fully operational in a variety of embodiments; and which is otherwise entirely successful in achieving its operational objectives. 
         [0073]    Although the invention has been herein shown and described in what is conceived to be the most practical and preferred embodiments, it is recognized that departures may be made therefrom within the scope of the invention which is not to be limited to the illustrative details disclosed. Having described my invention, what I claim as new and desire to secure by Letters Patent is:
