Patent Abstract:
The biological test kit is a device for drawing and, optionally, testing biological samples. The biological test kit is an array of lancets set in wells in a rigid base. Each lancet well is covered by a protective cover which when deformed permits the lancet to puncture a user or other patient. In one embodiment the biological test kit employs distinct covers for each lancet and in another the covers are formed from sheet material formed into blisters which cover the lancet.

     BACKGROUND 
     The biological test kit relates to the field of patient operated biological testing apparatus 
     The use of Lancets in biological testing is well known in the art. In some inventions the Lancet is placed in or formed as part of a blister or bubble. A user causes the blister to collapse and thereby move the lancet to puncture the skin of the patient or user. U.S. Pat. No. 5,231,993 to Haber et al, U.S. Pat. No. 5,636,640 to Staehlin, U.S. Pat. No. 5,505,212 to Keljmann et al, U.S. Pat. No. 5,054,499 to Swierczeck, published patent applications 20080058726 to Jina, 20070129620 to Krulevich et al, and 20090099427 also to Jina are all typical of this approach. The present invention provides an array of lancets, each of which is housed and protected in a well which is covered by a flexible cover. 
     BRIEF SUMMARY OF THE INVENTION 
     The biological test kit is a device for drawing and, optionally, testing biological samples. The biological test kit comprises: a rigid first layer, one or more lancets secured to the rigid first layer, said lancets each having a sharp region disposed substantially away from the rigid first layer, one or more second layers disposed in an opposed arrangement relative to the rigid first layer, the rigid first layer and second layers being arranged to form one or more cavities, each of the one or more second layers forming one or more covers, each cover over one of the lancets; and each of the one or more covers having a first unconstrained configuration in which the lancet sharp region does not protrude past or through the cover and having a second compressed configuration in which the lancet&#39;s sharp region protrudes through the cover. In one embodiment the biological test kit employs distinct covers for each lancet and in another the covers are formed from sheet material formed into blisters which cover the lancet.

     DETAILED DESCRIPTION OF THE INVENTION 
     The biological test kit  1  comprises: a rigid first layer  2 , one or more lancets  3  secured to the rigid first layer  2 , said lancets  3  each having a sharp region  4  disposed substantially away from the rigid first layer  2 , one or more second layers  5  disposed in an opposed arrangement relative to the rigid first layer  2 , the rigid first layer  2  and second layers  5  being arranged to form one or more cavities  6  there-between, each of the one or more second layers  5  forming one or more covers  7 , each cover  7  over one of the lancets  3 ; and each of the one or more covers  7  having a first unconstrained configuration  8  in which the lancet  3  sharp region  4  does not protrude past or through the cover  7  and having a second compressed configuration  9  in which the lancet&#39;s  3  sharp region  4  protrudes through the cover  7 . 
     The rigid first layer  2  is composed of a rigid material such as plastic, wood, or metal. The rigid first layer  2  provides a foundation for construction of the biological test kit  1 . 
     Lancets  3  are small rods or bars constructed of metal or plastic with one end flattened and sharpened to facilitate making a small puncture site  10 , often optimized for puncturing human skin. In the biological test kit  1 , one or more lancets  3  are fixed in the rigid first layer  2  such that the sharp region  4  of the lancet  3  is positioned at a distance from the rigid first layer  2 . The lancets  3  may be placed in any pattern. 
     The second layer  5  is made of resilient material and is formed over the rigid first layer  2  to provide a cover  7  for each of the lancets  3 . This may be accomplished in any number of ways including, but not limited to, forming the second layer  5  into a number of blisters where each blister forms a cover  7  for one of the lancets  3  and forms an airtight cavity  6  covering and surrounding the lancet  3 . These blisters are sized so that when a user applies sufficient compressive force against the rigid first layer  2  and the second layer  5  the blister is pierced by the lancet  3  along with the skin of the user. The user may accomplish this by pinching the blister between a thumb and index finger, or any other suitable body parts  20 . Alternatively, the user may apply this pinching force by placing the rigid first layer  2  on a supporting surface and pressing the appropriate body part  20  on the blister. The material chosen for the second layer  5 , and therefore the blisters, may be sufficiently resilient to cause the blister to reform into its original position, and cover  7  the lancet  3 , when the user applied pressure is removed. 
     The biological test kit  1  may include any number of second layers  5 . However, each of the second layers  5  may serve a unique purpose such as resealing the hole made by passage of the Lancet  3  through the cover  7  or providing a dose of antibiotic, or providing an indication as to the chemical analysis of the biological sample  13 . 
     The biological test kit  1  may also include test strips  12  which capture biological samples  13  resulting from the action of the lancet  3  such as fluid exuded from the puncture site  10  created by the lancet  3 . 
     The biological test kit  1  may also include a test apparatus  14  for analysis of the samples  13  gathered as above. This test apparatus  14  may include the ability to display the results of the analysis in any suitable manner, such as a digital readout or color change of the test strip  12 . 
     In a second embodiment  15  the biological test kit  1  includes a rigid first layer  2  and lancets  3  as above with a distinct well  16  provided for each lancet  3  within the rigid first layer  2  and a distinct cover  7  for each lancet  3 . Each well  16  has a closed end  17  and an open end  18 . A lancet  3  is fixed to the closed end  17  of each well  16 . Each well  16  is formed with a ledge  19  around the interior of its open end  18 . The well  16  and the ledge  19  are sized to permit insertion of a cover  7  said cover  7  supported by the ledge  19 . 
     Each cover  7  is formed as a compound curve and formed from a flexible and resilient material such that the cover  7  can be compressed by an applied force into a compressed configuration  9  and when said force is removed the cover  7  returns to its unconstrained configuration  8 . When the cover  7  is placed in the well  16  with the convex surface facing away from the closed end  17  of the well  16  and the cover  7  is in the unconstrained configuration  8  the cover  7  conceals the lancet  3 . When so placed and pressed into the compressed configuration  9  the lancet  3  protrudes through the cover  7  to a prescribed distance. When a user desires to produce a puncture site  10  from which a biological sample  13  may be taken, the user presses the cover  7  with sufficient force that the lancet  3  pierces the cover  7  and the user&#39;s finger, or other body part  20 . It is to be noted that the cover  7  may or may not include a hole through which the lancet  3  passes. 
     The biological test kit  1  may be further provided with one or more protective or indicative layers  21 . The protective or indicative layers  21  may be made of a material which is flexible yet non porous to prevent intrusion of foreign material when serving a protective function and made of a chemically reactive material when serving an indicative function or be made of a material suitable for protection and treated with an indicative substance to serve both purposes. 
     As above the rigid first layer  2  may be provided with a test apparatus  14  and test strips  12 . 
     The biological test kit  1  may be used according to the following steps: collecting biological samples  13  comprising the steps, compressing a lancet  3  cover  7  onto a stationary lancet  3  until said lancet  3  pierces said cover  7  and said user, producing a puncture site  10 . This method may further include the step of collecting biological samples  13  from said puncture site  10 . This method may also comprise the step of using a testing apparatus  14  to measure one or more chemical properties of said biological sample  13 .
