DETAILED DESCRIPTION
(32) Referring now to the figures generally wherein like numbered features shown therein refer to like elements throughout unless otherwise noted. The present disclosure relates to a medical testing apparatus and method of use, and more particularly, a medical testing apparatus for carrying a testing agent, the testing apparatus utilized in penetrating a patient's tissue during a medical procedure. While the illustrated example embodiment describes the medical testing apparatus' application of allergens/or antigens into the skin of a patient, it should be appreciated that other medical uses of applying fluids into a patient's tissue with the testing apparatus are within the spirit and scope of the present disclosure.
(33) For the purposes of this specification, penetrating a patient's tissue is intended to include, but is not limited to, the patient's skin, epidermis, dermis, and subcutaneous layers. While the medical testing apparatus utilizes various allergens in the testing of patients for various allergic reactions, the testing apparatus may use other diagnostic or medical treatment agents without departing from the spirit and scope of the claimed disclosure.
(34)
(35) The cover 26 has the same dimensions as the base 22, but is slightly larger than the cradle 24, forming a peripheral self or recess 28 for carrying the cover. In the illustrated example embodiment, the docketing station 20 is constructed such that the testing apparatuses 10 are stationed in relatively close proximity (near contact) with each other, but could be expanded in size to include over an inch of space between each testing apparatus without departing from the spirit and scope of the claimed disclosure. The cover 26 provides protection to the testing apparatuses 10 and agent or fluids therein from the environment, debris, evaporation, or any combination thereof.
(36)
(37) In the illustrated example embodiment, the arcuate rail 11 sides 14, 16, and surfaces 30, 32 share a common arcuate center AC as illustrated in
(38) Projecting from, and as part of the arcuate rail 12 are a plurality of tips 40 that extend outward substantially orthogonally along the center of the lower arcuate surface 32 over the length of the arcuate rail 12. In one illustrated example embodiment, the plurality of tips alternate between a blunt tip 42 and a reed or a cannulus tip 44, such as
(39) Illustrated in
(40)
(41)
(42) Illustrated in
(43)
(44) In one example embodiment, the reed tips 44 are made from biomedical materials, such as biomedical plastic and/or biomedical metal suitable for inserting into a patient's skin. In the example embodiment the reed tips 44 are press-fit into corresponding openings 45 molded into the lower arcuate surface 32. This would allow the reed tips 44 to be purchased from a separate medical supplier, and replacement of the reed tips by a medical professional such as a nurse, doctor, or technician after each use. In an alternative example embodiment, the reed tips 44 are molded directly into the lower arcuate surface.
(45) In the illustrated example embodiment of
(46)
(47) The support openings 54 include blunt openings 58 alternating between reed openings 60. The reed openings 60 are oversized to receive test tubes 52 for removal remote filling of fluid 50. In an example embodiment, the reed openings/60 are formed into the cradle 24 like that of the blunt openings 58 and the fluid 50 is located within the openings without a test tube 52. In the illustrated example embodiment, the test tubes 52 provide sufficient clearance to avoid contact or bending of reed tips 44.
(48) When the testing apparatus 10 is nested in the docking station 20, the reed tips 44 are sufficiently submerged in the test tubes 52 to provide capillary flow of the fluid 50 into the cavity cups 48. In the illustrated example embodiment the blunt openings 58 provide clearance about each of the blunt tips 42.
(49) In an alternative example embodiment, the blunt openings 58 provide slight contact with the blunt tips 42 in order to provide additional support to the testing apparatus 10 in its rested or nested position on the cradle 24. In one example embodiment a different, more pliable materials such as rubber or low durometer plastics are used to form the cradle 24, further enhancing the removal and support of the testing apparatuses 10. It should be appreciated that the test tubes 52 could be placed in all the openings to provide removable fluid to both blunt and reed tips. Or alternatively, to all reed or blunt tips as illustrated in the example embodiments of

(51) The illustrated example embodiment of the testing apparatus 10 of
(52) Pain and discomfort is further minimized in the testing apparatuses' 10 design by starting and ending with a blunt tip 42 and the curved arcuate rail 12. The curved arcuate rail 12 allows for a uniform load or force on the patient's treatment region, such as an arm or a back area. The DDS design employed by the testing device 10 includes alternating tip types, namely blunt to reed, advantageously distracting the patient from nociception of the reed or testing heads 44 when engaged by the blunt tip 42.
(53) Illustrated in
(54) Referring now to
(55) During use, the medical testing apparatus 10 is held by a medical practitioner 102, such as a nurse or doctor's fingers and thumb along spaced sides 14, 16 of the arcuate rail. The palm of the medical practitioner straddles the arcuate annular handle 18. The cavity cups 48 of reed or testing tips 44 are filled with fluid 50 such as an antigen or allergen by capillary retraction from the test tubes 52 of the cradle 24 described above.
(56) The medical practitioner 102 then first contacts the patient's skin (in the start position of
(57) As further illustrated in the example embodiment of
(58) In the illustrated example embodiment, the reed 44 and blunt 42 tips are substantially the same overall length. In another example embodiment, the reed 44 and blunt tips extend from the arcuate lower surface 32 approximately two (2) cm, allowing for sufficient penetration of the patient's tissue, while further allowing for uniform pressure in the contact of the arcuate lower surface 32.
(59) While the example embodiment of the testing apparatus 10 has been illustrated with ten (10) reed tips 44 and eleven (11) blunt tips 42, it should be appreciated that any number of tips could be used in an alternating combination that start and end with a blunt tip to achieve the apparatus' DDS comfort design. In addition, it should be appreciated that the medical practitioner 102 may wish to apply the agent or fluid 50 from the tester 10 by gripping and rocking the annular arcuate handle 18 as a personal preference.
(60) In the illustrated example embodiment of
(61) The double rail testing apparatus 10 includes a handle 18 for the medical practitioner to grip that subtends the first and second arcuate rails 12A and 12B. In the illustrated example embodiment, the handle 18 is molded into the rails 12A and 12B. The practitioner may then use both rails for testing and/or marking a patient before disposing of the apparatus 10. In one example embodiment, the double rail testing apparatus 10 is provided in a kit 11, as illustrated in
(62) Illustrated in
(63) While in another example embodiment illustrated in
(64) What have been described above are examples of the present invention. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the present invention, but one of ordinary skill in the art recognize that many further combinations and permutations of the present invention are possible. Accordingly, the present invention is intended to embrace all such alterations, modifications, and variations that fall within the spirit and scope of the appended claims.
