Abstract

A test sensor container for use with an analyte measuring system may include a cartridge that includes a base, two opposite sidewalls extending away from the base, and a plurality of compartments each dimensioned to hold a test sensor. At least one of the two opposite sidewalls is oriented at an acute angle relative to a reference axis that is perpendicular to the base. The test sensor container may further include at least one foil cover sealing the plurality of compartments and an ejection mechanism.

First claim

What is claimed is:

1. A test sensor container for use with an analyte measuring system, comprising:
a cartridge including a base, a top portion, two opposite sidewalls extending from the base to the top portion, and a plurality of compartments arranged linearly along a longitudinal axis, wherein each compartment is dimensioned to hold a test sensor, and at least one of the two opposite sidewalls is entirely linear forming a straight line from the base to the top portion and oriented at an acute angle relative to a reference axis perpendicular to the base;
at least one foil cover sealing the plurality of compartments; and
an ejection mechanism adjacent the cartridge and configured to eject a test sensor from the cartridge by causing the test sensor to pierce the at least one foil cover at the at least one of the two opposite sidewalls to create an opening through which the test sensor is ejected.

2. The test sensor container of claim 1 , wherein the at least one foil cover comprises a single foil cover.

3. The test sensor container of claim 1 , wherein the plurality of compartments extends between the two opposite sidewalls.

4. The test sensor container of claim 1 , wherein the at least one foil cover extends over the two opposite sidewalls.

5. The test sensor container of claim 1 , wherein the two opposite sidewalls are each oriented at an acute angle relative to the reference axis perpendicular to the base.

6. The test sensor container of claim 1 , further comprising a plurality of test sensors stored respectively in the plurality of compartments and arranged side by side along a length of the cartridge extending along the longitudinal axis.

7. The test sensor container of claim 6 , wherein each of the plurality of test sensors has a side extending parallel to the reference axis and adjacent the at least one of the two opposite sidewalls oriented at the acute angle.

8. The test sensor container of claim 7 , wherein the ejection mechanism comprises an ejection blade configured to push one of the plurality of test sensors such that the side extending parallel to the reference axis pierces the at least one foil cover at the at least one of the two opposite sidewalls oriented at the acute angle.

9. The test sensor container of claim 1 , wherein each compartment of the plurality of compartments comprises a cavity for receiving a desiccant material therein.

10. The test sensor container of claim 1 , wherein the ejection mechanism is further configured to pierce a first portion of the at least one foil cover at the other of the two opposite sidewalls to open only one of the plurality of compartments at a time without opening any other one of the plurality of compartments and to move through the only one compartment toward the one of the two opposite sidewalls.

11. The test sensor container of claim 10 , wherein the ejection mechanism comprises a flexible blade movable between a first blade position and a second blade position, wherein no portion of the flexible blade is located within any one of the plurality of compartments in the first blade position, and at least a portion of the flexible blade is located within one of the plurality of compartments in the second blade position, the flexible blade piercing the first portion of the at least one foil cover as a result of moving from the first blade position to the second blade position.

12. The test sensor container of claim 11 , wherein the ejection mechanism further comprises an ejection button configured to move the flexible blade, the flexible blade having a first end and a second end, the first end connected to the ejection button and the second end not connected to any structure.

13. The test sensor container of claim 11 , wherein the ejection mechanism further comprises a rotatable spindle about which the flexible blade has a first blade portion extending in a first direction and a second blade portion extending in a second direction.

14. The test sensor container of claim 13 , wherein the second blade portion is substantially perpendicular to the first blade portion.

15. The test sensor container of claim 13 , further comprising an ejection port configured to receive there through the test sensor, wherein the second blade portion is aligned with the ejection port.

16. A test sensor container for use with an analyte measuring system, comprising:
a cartridge including a base, two opposite sidewalls extending away from the base, and a plurality of compartments arranged linearly along a longitudinal axis, wherein each compartment is dimensioned to hold a test sensor, and at least one of the two opposite sidewalls is oriented at an acute angle relative to a reference axis perpendicular to the base;
at least one foil cover sealing the plurality of compartments;
an ejection mechanism adjacent the cartridge and configured to break a first portion of the at least one foil cover at one of the two opposite sidewalls to open only one of the plurality of compartments at a time without opening any other one of the plurality of compartments; and
a housing having the cartridge therein, wherein the ejection mechanism comprises:
a lever pivotally coupled to the housing, the lever movable from a first lever position substantially parallel to the longitudinal axis to a second lever position substantially perpendicular to the longitudinal axis; and
an ejection blade mounted to the lever and movable between a first blade position and a second blade position, wherein no portion of the ejection blade is located within any one of the plurality of compartments in the first blade position, and at least a portion of the ejection blade is located within one of the plurality of compartments in the second blade position, the ejection blade breaking the first portion of the at least one foil cover as a result of moving from the first blade position to the second blade position.

17. The test sensor container of claim 16 , wherein the ejection blade is slidably mounted to the lever.

18. The test sensor container of claim 16 , wherein the ejection blade is movable linearly between the first blade position and the second blade position.

19. The test sensor container of claim 16 , wherein the ejection blade is movable substantially perpendicular to the longitudinal axis from the first blade position to the second blade position.

20. The test sensor container of claim 16 , wherein the ejection blade is made of a substantially rigid material.
