Abstract

A test-sensor cartridge including a plurality of test sensors adapted to assist in determining an analyte concentration of a fluid sample. The cartridge further includes a plurality of walls forming a cavity therein. The cavity is adapted to include the plurality of test sensors. At least one of the plurality of walls forms at least one aperture. The cartridge further includes a lid adapted to enclose the cavity. The cartridge further includes a locking feature adapted to lock the lid to one or more of the walls. The locking feature is adapted to be disengaged by the at least one aperture receiving a projection of an analyte-testing instrument.

Claims

1. An analyte-testing system for determining an amount of an analyte in a fluid test sample, the analyte-testing system comprising:

a test-sensor cartridge including

a plurality of test sensors,

a plurality of walls forming a cavity therein, the cavity being adapted to include the plurality of test sensors, at least one of the walls forming at least one aperture,

a lid adapted to enclose the cavity, and

a locking feature adapted to lock the lid to one or more of the walls, at least a portion of the locking feature being positioned within the at least one aperture; and

an analyte-testing instrument including

a body portion,

at least one opening formed in the body portion, the at least one opening being configured to receive one of the plurality of test sensors, and

at least one projection extending from the body portion,

the locking feature being adapted to be disengaged by the at least one aperture receiving the at least one projection of the analyte-testing instrument.

2. The analyte-testing system of claim 1, wherein the locking feature includes a latch coupled to the cartridge and a corresponding notch coupled to the lid.

3. The analyte-testing system of claim 1, wherein the locking feature is coupled to the lid, the locking feature further including a tab portion extending into the aperture.

4. The analyte-testing system of claim 1, wherein the aperture extends completely through the cartridge.

5. The analyte-testing system of claim 1, wherein the coding feature is positioned on an exterior surface of one of the walls.

6. The analyte-testing system of claim 1, the test-sensor cartridge further including a coding feature positioned on at least one of the walls or the lid, the coding feature being adapted to be read by a reading device positioned on the analyte-testing instrument.

7. The analyte-testing system of claim 6, wherein the coding feature is located on a surface of the lid adjacent to the cavity and the projection includes reading device.

8. The analyte-testing system of claim 6, wherein the aperture is adapted to receive a first projection of a first analyte-testing instrument with which the cartridge is compatible and wherein the aperture may not receive a second projection of a second analyte-testing instrument with which the cartridge is incompatible.

9. A method of modifying testing parameters of an analyte-testing instrument, the method comprising the acts of:

providing a test-sensor cartridge including a plurality of walls forming a cavity therein, the cavity being adapted to include a plurality of test sensors, at least one of the walls forming at least one aperture, the cavity being enclosed by a lid having a locking feature adapted to lock the lid to one or more of the walls, the test sensors being adapted to assist in the determination of a concentration of an analyte in a fluid sample, at least one of the lid or the walls having a coding feature being positioned thereon;

providing an analyte-testing instrument having at least one projection located thereon, the analyte-testing instrument including a reading device;

disengaging the locking feature by contacting the cartridge to the analyte-testing instrument such that the at least one projection mates with the at least one aperture;

reading the coding feature using the reading device;

modifying at least one testing parameter of the analyte-testing instrument based on information received by reading the coding feature.

10. The method of claim 9, wherein the locking feature includes a latch coupled to the cartridge and a corresponding notch coupled to the lid.

11. The method of claim 9, wherein the locking feature includes a tab portion extending into the aperture.

12. The method of claim 9, wherein the aperture extends completely through the cartridge.

13. The method of claim 9, wherein the coding feature is located on a surface of the lid adjacent to the cavity and the reading device is positioned on the at least one projection.

14. The method of claim 9, wherein the act of disengaging the locking feature includes the at least one projection forcing the locking feature out from the at least one aperture.
