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 test meter for analyzing a body fluid sample applied to a test strip, the test meter comprising:

an outer housing having an opening;

an actuator positioned adjacent the outer housing;

a dispensing member movably connected to the actuator, the dispensing member having a first end and a second end, the first end being a free end and the second end being a fixed end, the dispensing member configured to rotate about the fixed end; and

a cartridge for storing a plurality of stacked test strips for distribution through the opening, the cartridge having a linear channel configured to permit movement of the dispensing member there through, the cartridge comprising a covering element hingedly connected to the dispensing member and configured to move the dispensing member when the covering element moves between a first position and a second actuated position, the covering element engaged with the actuator and moving from the first position to the second actuated position when the actuator is actuated;

wherein the plurality of stacked test strips is biased toward the dispensing member, and

wherein each time the actuator is actuated, the dispensing member is rotated about the fixed end, and the free end of the dispensing member moves along the linear channel to move one test strip from the plurality of stacked test strips through the opening and another test strip from the plurality of stacked test strips is biased toward the dispensing member.

2. The test meter of claim 1, wherein the dispensing member is a flexible arm, and wherein when the actuator is actuated, the dispensing member moves one test strip across a top of the plurality of stacked strips.

3. The test meter of claim 1, wherein the dispensing member and plurality of test strips are positioned within the outer housing.

4. The test meter of claim 1, wherein only the dispensing member is positioned within the outer housing, and the cartridge is connected to the outer housing.

5. The test meter of claim 1, wherein the test meter is able to analyze the fluid sample while the dispensed test strip remains within the opening.

6. The test meter of claim 1, wherein the cartridge further comprises:

an interior cartridge housing joined with the outer housing.

7. The test meter of claim 1, wherein the linear channel is constructed and arranged to provide a pathway that allows the dispensing member to move between a stationary position and a dispensing position within the channel, wherein the dispensing member is closer to the opening in the dispensing position than in the stationary position.

8. The meter of claim 1, wherein the cartridge further comprises:

an interior cartridge housing for housing the dispensing member, the interior cartridge housing including a test strip storage area for storing the plurality of stacked test strips therein, each of the test strips having edges aligned with one another.

9. The test meter of claim 1, wherein each of the stacked test strips has an outer edge, and wherein each of the outer edges is aligned with one another.

10. The test meter of claim 8, further comprising a seal extending between the interior cartridge housing and the outer housing.

11. The test meter of claim 1, wherein the cartridge further comprises an outer housing, the covering element configured to move along a length of an axis between the first position, wherein a bottom surface of the covering element joins with a surface of the outer housing to seal the cartridge closed, and the second actuated position, wherein the bottom surface of the covering element is spaced away from the surface of the outer housing.

12. The test meter of claim 1, wherein the dispensing member includes a notch and the covering element further comprises an opening sized to receive the notch, the opening configured to permit the notch to move within the opening when the covering element is moved from the first position to the second actuated position.

13. A cartridge for storing a plurality of stacked test strips in a test meter, the cartridge comprising:

an outer casing;

a covering element removably joined together with the outer casing, wherein the covering element is configured to move along a length of an axis between a first axial position, wherein at least a portion of the covering element is adjacent the outer casing, and a second axial position, wherein the at least a portion of the covering element is spaced away from the outer casing in the second axial position;

a dispensing assembly seated within the outer casing, the dispensing assembly further comprising;

a test strip storage area for storing the plurality of stacked test strips therein, each of the test strips having opposed edges aligned with one another; and

a dispensing member movably connected to the covering element and configured to rotate between a first rest position and a second dispensing position, the dispensing member having a first end contacting a single test strip of the plurality of test strips and a second fixed end, the dispensing member configured to rotate about the fixed end; and

a linear channel configured to allow movement of the free end there through,

wherein the plurality of stacked strips is biased toward the dispensing member, and

wherein when the covering element is moved away from the dispensing assembly, the dispensing member rotates about the fixed end and the free end of the dispensing member moves through the linear channel and moves the one test strip through an opening.

14. The cartridge of claim 13, wherein the at least a portion of the covering element is a bottom surface of the covering element, and wherein when the covering element is in the first axial position, the bottom surface of the covering element is closer to a receiving surface of the outer casing than when the covering element is in the second axial position and the bottom surface is joined with the receiving surface of the outer casing to seal the cartridge closed.

15. The cartridge of claim 13, wherein the dispensing member includes a notch and the covering element further comprises an opening sized to receive the notch, the opening configured to allow the notch to move within the opening when the covering element is moved from the first axial position to the second axial position.
