Abstract

A ring-shaped registration device for receiving and holding an activated test strip having a reagent area adapted to receive a blood sample. The registration device is slidably received on the outer peripheral surface of a cylindrical vial on which markings to indicate a range of possible results which might be evidenced by a blood sample. The device includes a central member having a support region for slidably receiving the activated test strip and defining a window for outlining markings on the surface of the vial and on the reagent area of the activated test strip. The reagent area is held in substantially tangential relationship relative to the outer peripheral surface of the vial so as to be selectively positioned intermediate adjacent markings on the surface of the vial. This enables the user to compare an actual blood sample with the range of possible conditions and match the sample with the markings on the vial.

Claims

1. A system of testing for glucose in whole blood comprising:

a cylindrical vial for containing a plurality of inactivated test strips which are selectively removable therefrom, each test strip provided with a reagent area adapted to receive a blood sample thereon and thereby being activated to indicate a particular color consistent with the condition of the blood and the time elapsed since reception of the blood sample thereon, said vial having an outer peripheral surface;

a plurality of graduated markings on said peripheral surface providing a range of different colors which are indicative of a range of possible conditions which might be evidenced by an activated test strip;

holder means slidably mounted on said outer peripheral surface and including a support region for slidably receiving the reagent area of an activated test strip, said holder means defining a window for outlining, simultaneously, at least one of said markings on said peripheral surface and on the reagent area of the activated test strip;

thereby enabling the reagent area on the activated test strip to be matched with an appropriate one of said markings on said peripheral surface to thereby indicate the condition of the blood being sampled.

2. A system as set forth in claim 1

wherein said holder means includes;

a main component including said support region and defining the window; and

a subcomponent removably mounted on said main component adjacent said support region, said subcomponent defining an opening for slidably receiving a test strip therethrough and including guide means cooperatively positioned relative to the opening for guiding the test strip into the window when said subcomponent is mounted on said main component.

3. A system as set forth in claim 2

wherein said subcomponent is movable between a disengaged position separate from said main component and an engaged position intimately abutting said main component, and including:

mutually cooperating key means on said main component and on said subcomponent for cooperatively guiding said subcomponent to said engaged position; and

mutually engaging detent means on said main component and on said subcomponent, respectively, for releasably holding said subcomponent in said engaged position.

4. A system as set forth in claim 1

wherein said holder means includes:

first and second opposed side members; and

including;

first and second opposed legs integral with and extending away from said first and second side members, respectively, said first leg having a gripping member distant from said first side member for slidably engaging said outer peripheral surface and said second leg having a gripping member distant from said second side member for slidably engaging said outer peripheral surface;

whereby the window can be moved both longitudinally along the length of said vial and circumferentially thereof.

5. A system as set forth in claim 4

wherein said first and second legs are resilient relative to said first and second side members, respectively, and are biased towards each other so as to securely engage said outer peripheral surface.

6. A system as set forth in claim 4

wherein said central member includes:

an arcuate undersurface generally encompassing the window therein for slidably engaging the outer peripheral surface of said vial.

7. A system as set forth in claim 4

wherein said first side member defines an entry aperture for slidably receiving a test strip therethrough and includes:

guide means cooperatively positioned relative to the entry aperture for guiding the test strip into the window.

8. A system as set forth in claim 7

wherein said second side member includes a slot adjacent the window for receiving an end of the test strip proximate to the reagent area thereof for thereby stabilizing the test strip as said holder means is moved on said peripheral surface.

9. A system as set forth in claim 7

wherein said plurality of markings include:

individual markings at a plurality of spaced locations along the length of said vial, adjacent ones of said markings being spaced by a distance substantially equal to the width of the test strip enabling movement of said holder means on said outer peripheral surface such that the reagent area of an activated test strip is positioned intermediate said adjacent markings.

10. Apparatus enabling the reagent area of an activated test strip to which a blood sample has been applied to be matched with graduated markings indicative of a range of possible conditions which might be evidenced by a blood sample, which markings are provided on the outer peripheral surface of a cylindrical vial, comprising:

holder means slidably mounted on the outer peripheral surface of the vial and including a central member having a support region for slidably receiving and holding the activated test strip substantially tangent to the outer peripheral surface of the vial, said central member defining a window for outlining, simultaneously, at least one of the markings on the peripheral surface and on the reagent area of the activated test strip.

11. Apparatus as set forth in claim 10

wherein said central member includes:

an arcuate undersurface generally encompassing the window therein for slidably engaging the outer peripheral surface of the vial.

12. Apparatus as set forth in claim 10

wherein the plurality of markings on the outer peripheral surface of the vial include individual markings at a plurality of spaced locations along the length of the vial, adjacent ones of the markings being spaced by a distance generally equal to the width of the test strip;

and

wherein said central member includes;

first and second opposed side members; and

including;

first and second opposed legs integral with and extending away from said first and second side members, respectively, having a gripping member distant from said first side member for slidably engaging the outer peripheral surface of the vial and said second leg having a gripping member distant from said second side member for slidably engaging the outer peripheral surface of the vial;

said first side member defining an entry aperture for slidably receiving a test strip therethrough and including guide means cooperatively positioned relative to the entry aperture for guiding the test strip into the window;

said second side member including a slot adjacent the window for receiving an end of the test strip proximate to the reagent area thereof for thereby stabilizing the test strip and holding the test strip in a substantially tangential relationship relative to the outer peripheral surface of the vial such that the reagent area of an activated test strip can be selectively positioned intermediate adjacent markings on the outer peripheral surface of the vial.

13. Apparatus as set forth in claim 12

wherein said central member includes:

an arcuate undersurface generally encompassing the window therein for slidably engaging the outer peripheral surface of the vial.

14. A system as set forth in claim 10

wherein said holder means includes:

a main component including said support region and defining the window; and

a subcomponent removably mounted on said main component adjacent said support region, said subcomponent defining an entry aperture for slidably receiving a test strip therethrough and including guide means cooperatively positioned relative to the entry aperture for guiding the test strip into the window when said subcomponent is mounted on said main component.
