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:

a cartridge for storing a plurality of stacked test strips and for dispensing individually the plurality of stacked test strips, the cartridge comprising;

an outer housing having an opening and configured to receive the plurality of stacked test strips in a first direction parallel to a height of the plurality of stacked test strips;

a cover portion removably joined to the outer housing, the cover portion having a top surface and comprising at least one connection member extending perpendicularly away from the top surface and into the outer housing in the first direction; and

a dispensing member received within the outer housing and having a first end and a second end, the first end being a free end and the second end hingedly connected to the at least one connection member of the cover portion, the dispensing member configured to rotate about the second end; and

a meter housing configured to receive the cartridge therein, the meter housing comprising an actuator attached to the cover portion;

wherein;

in response to actuation of the actuator, the cover portion moves between a first position and a second actuated position; and

in response to movement of the cover portion, the dispensing member rotates about the second end wherein the first end is configured to engage and move one test strip from the plurality of stacked test strips through the opening.

2. The test meter of claim 1, wherein the first end and the second end of the dispensing member are each rigid and the dispensing member has a flexible arm portion extending between the first end and the second end.

3. The test meter of claim 1, wherein the dispensing member has a rounded shape.

4. The test meter of claim 1, wherein the dispensing member has an arm portion extending between the first end and the second end, the arm portion having an I-beam shaped profile.

5. The test meter of claim 1, further comprising a seal extending between the cover portion and the outer housing to create an airtight seal in the first position.

6. The test meter of claim 1, wherein the cartridge comprises an interior cartridge housing configured to receive the plurality of stacked test strips, wherein the outer housing is configured to receive the interior cartridge housing.

7. The test meter of claim 1, wherein the cartridge comprises a biasing member configured to bias the plurality of stacked test strips towards the cover portion.

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

a cartridge for storing a plurality of stacked test strips and for dispensing individually the plurality of stacked test strips, the cartridge comprising;

an outer housing having an opening and configured to receive the plurality of stacked test strips in a first direction parallel to a height of the plurality of stacked test strips;

a cover portion removably joined to the outer housing, the cover portion having a top surface and comprising at least one connection member extending perpendicularly away from the top surface and into the outer housing in the first direction; and

a dispensing member received within the outer housing and having a first end and a second end, the first end being a free end and the second end hingedly connected to the at least one connection member of the cover portion, the dispensing member configured to rotate about the second end; and

a meter housing configured to receive the cartridge therein, the meter housing comprising an actuator attached to the cover portion;

wherein;

in response to actuation of the actuator, the cover portion moves along a length of an axis between a first position, wherein a bottom surface of the cover portion joins with a surface of the outer housing to seal the cartridge closed, and a second actuated position, wherein the bottom surface of the covering element is spaced away from the surface of the outer housing; and

in response to movement of the cover portion, the dispensing member is configured to engage and move one test strip from the plurality of stacked test strips through the opening.

9. The test meter of claim 8 wherein, in response to movement of the cover portion, the dispensing member is configured to rotate about the second end, and the first end of the dispensing member is configured to engage and move one test strip from the plurality of stacked test strips through the opening.

10. The test meter of claim 8, wherein the dispensing member includes a notch and the cover portion has an aperture sized to receive the notch, the notch configured to move within the aperture in response to the cover portion moving from the first position to the second actuated position.

11. The test meter of claim 8, wherein the cover portion comprises an elongated rounded cap with a pair of the connection members extending away from the elongated rounded cap.

12. The test meter of claim 8, wherein the cartridge comprises an interior cartridge housing configured to receive the plurality of stacked test strips, and the outer housing is configured to receive the interior cartridge housing.

13. The test meter of claim 12, wherein the interior cartridge housing comprises a main body and at least one protruding leg extending away from the main body.

14. The test meter of claim 13, wherein the at least one protruding leg has a channel configured to receive the dispensing member and to provide a pathway for the dispensing member to move therein in response to movement of the cover portion.

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

an outer housing;

a cover portion removably joined with the outer housing, the cover portion having a top surface and comprising at least one connection member extending perpendicularly away from the top surface and into the outer housing; and

a dispensing assembly seated within the outer housing, the dispensing assembly comprising;

a test strip storage area for storing the plurality of stacked test strips therein in a first direction parallel to a height of the plurality of stacked test strips, wherein the at least one connection member extends alongside the test strip storage area in the first direction, and

a dispensing member movably connected to the at least one connection member of the cover portion and configured to rotate between a first position and a second dispensing position, the dispensing member having a first end configured to contact a single test strip of the plurality of test strips;

wherein;

the cover portion is configured to move along a length of an axis between a first axial position, wherein at least a portion of the cover portion is adjacent the outer housing, and a second axial position, wherein the at least a portion of the cover portion is spaced away from the outer housing in the second axial position; and

in response to the cover portion moving to the second axial position, the dispensing member is configured to move one of the plurality of stacked test strips through an opening.

16. The cartridge of claim 15, wherein the at least a portion of the cover portion comprises a bottom surface and the outer housing comprises a receiving surface and, in response to being in the first axial position, the bottom surface forms an airtight seal with the receiving surface.

17. The cartridge of claim 15, wherein the dispensing member includes a notch and the cover portion has an aperture sized to receive the notch, the notch configured to move within the aperture in response to the cover portion moving from the first axial position to the second axial position.
