Abstract

A hand-held test meter and analytical test strip cartridge assembly combination includes a hand-held test meter with a test meter housing and an extractor with a test strip engagement feature, while the analytical test strip cartridge assembly includes a desiccant vial and an analytical test strip cartridge with a cartridge housing, a test strip presentation mechanism disposed within the cartridge housing, and a plurality of analytical test strips (each with at least one extractor engagement feature) disposed in the cartridge housing. The test meter housing is configured for operative engagement with the cartridge housing and the test strip presentation mechanism is configured to present a single analytical test strip from the plurality of analytical test strips for engagement with the extractor. Moreover, the analytical test strip cartridge is configured for operative disposition in the desiccant vial.

Claims

1. A hand-held test meter and analytical test strip cartridge assembly combination comprising:

a hand-held test meter including;

a test meter housing; and

an extractor with at least one test strip engagement feature; and

an analytical test strip cartridge assembly including;

a desiccant vial; and

an analytical test strip cartridge including;

a cartridge housing;

a test strip presentation mechanism disposed within the cartridge housing, the test strip presentation mechanism comprising at least one test strip retainer; and

a plurality of discrete analytical test strips disposed in the cartridge housing, each of the discrete analytical test strips having at least one extractor engagement feature and having a top layer and a bottom layer;

wherein the test meter housing is configured for operative engagement with the cartridge housing; and

wherein the test strip presentation mechanism is configured to present a single discrete analytical test strip from the plurality of discrete analytical test strips, and serves to splay part top and bottom layers of the single discrete analytical test strip, for engagement with the extractor; and

wherein the analytical test strip cartridge is configured for operative disposition in the desiccant vial.

2. The hand-held test meter and analytical test strip cartridge assembly combination of claim 1 wherein the extractor and test meter housing are configured such that:

the extractor is operatively extendable from the test meter housing into the cartridge housing upon engagement of the meter housing with the cartridge housing;

the extractor, upon operative extension into the cartridge housing, mechanically engages with the discrete analytical test strip presented by the test strip presentation mechanism via engagement between the test strip engagement feature of the extractor and the extractor engagement feature of the discrete analytical test strip; and

the extractor, upon disengagement of the test meter housing from the cartridge housing, removes the mechanically engaged discrete analytical test strip from the cartridge housing and retracts into the test meter housing.

3. The hand-held test meter and analytical test strip cartridge assembly combination of claim 1 wherein the desiccant vial includes a wall and a desiccant material molded into the wall.

4. The hand-held test meter and analytical test strip cartridge assembly combination of claim 1 wherein the cartridge housing includes an air communication opening configured for air communication between the plurality of discrete analytical test strips and the desiccant vial.

5. The hand-held test meter and analytical test strip cartridge assembly combination of claim 1 wherein the cartridge housing includes at least one living hinge.

6. The hand-held test meter and analytical test strip cartridge assembly combination of claim 1 wherein the cartridge housing includes a keyed opening;

and

wherein the test meter housing is configured for operative engagement with the keyed opening of the cartridge housing.

7. The hand-held test meter and analytical test strip cartridge assembly combination of claim 1 wherein the cartridge housing includes a center cavity configured for operative disposition of the plurality of discrete analytical test strips and the test strip presentation mechanism.

8. The hand-held test meter and analytical test strip cartridge assembly combination of claim 1 wherein the analytical test strip cartridge is configured for a press fit into the desiccant vial.

9. The hand-held test meter and analytical test strip cartridge assembly combination of claim 1 wherein the operative disposition of the analytical test strip cartridge in the desiccant vial provides a sealed desiccated enclosure for the discrete analytical test strips.

10. The hand-held test meter and analytical test strip cartridge assembly combination of claim 1 wherein the discrete analytical test strip is an electrochemical-based analytical test strip.

11. A method for employing a hand-held test meter and analytical test strip cartridge assembly combination, the method comprising:

engaging a meter housing of a hand-held test meter with a cartridge housing of an analytical test strip cartridge assembly, the analytical test strip cartridge assembly including a desiccant vial with an analytical test strip cartridge disposed therein, the analytical test strip cartridge including a test strip presentation mechanism disposed therein, the test strip presentation mechanism splaying apart top and bottom layers of an analytical test strip disposed within the cartridge housing;

extending an extractor of the hand-held test meter into the cartridge housing;

mechanically engaging the extractor with splayed analytical test strip being presented for mechanical engagement by the test strip presentation mechanism of the analytical test strip cartridge and with the mechanical engagement occurring via engagement between a test strip engagement feature of the extractor and an extractor engagement feature of the discrete analytical test strip; and

disengaging the meter housing from the cartridge housing such that the extractor removes the mechanically engaged discrete analytical test strip from the cartridge housing and retracts into the test meter housing.

12. The method of claim 11 further comprising:

determining an analyte in a bodily fluid sample applied to the mechanically engaged discrete analytical test strip; and

releasing the discrete analytical test strip from the mechanical engagement with the extractor using a test strip release mechanism of the hand-held test meter.

13. The method of claim 12 wherein the bodily fluid sample is a whole blood sample and the analyte is glucose.

14. The method of claim 11 wherein the discrete analytical test strip being presented is being presented from among a plurality of discrete analytical test strips disposed within the analytical test strip cartridge assembly.

15. The method of claim 11 wherein the desiccant vial includes a wall and a desiccant material molded into the wall.

16. The method of claim 11 wherein the cartridge housing includes an air communication opening configured for air communication between the plurality of discrete analytical test strips and the desiccant vial.

17. The method of claim 11 wherein the cartridge housing includes at least one living hinge.

18. The method of claim 11 wherein the cartridge housing includes a keyed opening;

and wherein the test meter housing is configured for operative engagement with the keyed opening of the cartridge housing.

19. The method of claim 11 wherein the cartridge housing includes a center cavity configured for operative disposition of the plurality of discrete analytical test strips and the test strip presentation mechanism.

20. The method of claim 11 wherein the analytical test strip cartridge is configured for a press fit into the desiccant vial.

21. The method of claim 11 wherein the operative disposition of the analytical test strip cartridge in the desiccant vial provides a sealed desiccated enclosure for the discrete analytical test strips.
