Abstract

A test meter for analyzing a body fluid sample applied to a test strip includes an outer housing having an opening, an actuator, and a cartridge positioned adjacent the outer housing. The cartridge further includes a dispensing member connected to the actuator, a plurality of stacked test strips biased toward the dispensing member, and a cartridge outer housing that is adjacent at least a portion of the dispensing member. Each time the actuator is actuated, the dispensing member is rotated to cause movement of one test strip from the plurality of stacked test strips through the opening, and another test strip is biased toward the dispensing member.

Claims

1. A method of dispensing a test strip for testing a body fluid sample applied thereto, the method comprising:

biasing a first test strip of a plurality of stacked test strips toward a dispensing member, the plurality of stacked test strips received through an opening in an outer housing of a cartridge in a direction parallel to a height of the plurality of stacked test strips, the cartridge configured to be placed into a housing of a test meter, the dispensing member received within the outer housing and having a first end and a second end, the first end hingedly connected inside the outer housing and the second end being a free end;

moving the dispensing member such that the second end pushes the first test strip across a top of the remaining plurality of stacked test strips and through a strip opening in the cartridge such that at least one edge and a portion of the first test strip is exposed outside the strip opening and an opposite edge of the first test strip remains within the cartridge; and

biasing a second test strip of the plurality of stacked test strips toward the dispensing member once the first test strip has been removed from the cartridge.

2. The method of claim 1, wherein the biasing of the first test strip and the second test strip comprises positioning a spring loaded block in the outer housing adjacent a bottom of the plurality of stacked test strips.

3. The method of claim 1, wherein the moving of the dispensing member comprises rotating the dispensing member about a fixed point to which the first end is hingedly connected.

4. The method of claim 1, wherein the moving of the dispensing member comprises moving a flexible arm of the dispensing member from a first position to a second position.

5. The method of claim 4, wherein the flexible arm extends between the first end and the second end.

6. The method of claim 1, wherein the moving of the dispensing member comprises moving linearly a cover portion of the cartridge, the cover portion connected to the dispensing member.

7. The method of claim 1, further comprising creating an airtight seal between the outer housing and a cover portion connected to the dispensing member.

8. A method of dispensing a test strip for testing a body fluid sample applied thereto, the method comprising:

moving linearly a cover portion of a cartridge for storing a plurality of stacked test strips, the plurality of stacked test strips received through an opening in the cartridge in a direction parallel to a height of the plurality of stacked test strips; and

in response to linear movement of the cover portion, moving a dispensing member received within the cartridge such that a second end of the dispensing member pushes a first test strip of the plurality of stacked test strips through a strip opening in the cartridge such that at least one edge and a portion of the first test strip is exposed outside the strip opening and an opposite edge of the first test strip remains within the cartridge, the dispensing member having a first end hingedly connected inside the cartridge.

9. The method of claim 8, wherein the moving of the dispensing member comprises rotating the dispensing member about a fixed point to which the first end is hingedly connected.

10. The method of claim 8, wherein the moving of the dispensing member comprises the second end of the dispensing member pushing the first test strip across a top of the remaining plurality of stacked test strips.

11. The method of claim 8, further comprising, prior to the moving linearly, connecting the cover portion to the dispensing member by receiving a notch of the dispensing member in an aperture of the cover portion.

12. The method of claim 8, further comprising, prior to the moving linearly, biasing the plurality of stacked test strips toward the dispensing member.

13. The method of claim 12, wherein the biasing comprises positioning a spring loaded block in the cartridge adjacent a bottom of the plurality of stacked test strips.

14. The method of claim 8, further comprising creating an airtight seal between the cover portion and an outer housing of the cartridge, the outer housing containing the dispensing member therein.

15. A method of dispensing a test strip for testing a body fluid sample applied thereto, the method comprising:

storing a plurality of stacked test strips in an outer housing of a cartridge through an opening in the cartridge in a direction parallel to a height of the plurality of stacked test strips;

moving linearly a cover portion of the cartridge, the cover portion having at least one connection member extending linearly into the outer housing; and

in response to linear movement of the cover portion, moving a dispensing member received within the outer housing such that the dispensing member pushes a first test strip of the plurality of stacked test strips through a strip opening in the outer housing such that at least one edge and a portion of the first test strip is exposed outside the strip opening and an opposite edge of the first test strip remains within the cartridge, the dispensing member movably connected to the at least one connection member of the cover portion.

16. The method of claim 15, further comprising, prior to the moving linearly, biasing the plurality of stacked test strips toward the dispensing member.

17. The method of claim 15, wherein the moving of the dispensing member comprises rotating the dispensing member about a fixed point to which a first end of the dispensing member is hingedly connected inside of the outer housing.

18. The method of claim 15, wherein the moving of the dispensing member comprises a second end of the dispensing member pushing the first test strip across a top of the remaining plurality of stacked test strips.

19. The method of claim 15, further comprising, prior to the storing, receiving an interior cartridge housing in the outer housing, the interior cartridge housing configured to receive the plurality of stacked test strips, wherein the interior cartridge housing comprises a main body and at least one protruding leg extending away from the main body, the at least one protruding leg having a channel configured to receive the dispensing member and to provide a pathway for the dispensing member to move therein in response to the linear movement of the cover portion.

20. The method of claim 15, further comprising creating an airtight seal between the cover portion and the outer housing.
