Abstract

A device and system for automatic handling of a sensor strip by a part of meter includes a sensor strip having a first section, a second section, and an intermediate section. The sensor strip includes at least a first opening about a first end thereof and a second opening about a second end thereof. A meter part includes a pair of pivoting catches configured to engage and grasp a sensor strip from a container containing a plurality of sensor strips. The sensor strip may thus be removed from a container for testing without need for manual handling of the strip by a user.

Claims

1. A meter for testing an analyte, the meter comprising:

a read-head configured for interrogating a reagent section of a sensor strip; and

a meter housing arranged about the read-head, the meter housing comprising;

a first lower catch and a second lower catch pivotably mounted on the meter housing;

a first bias element coupling the first and second lower catches to one another;

a first lower cam element and a second lower cam element in engagement with the first and second lower catches, respectively;

a first upper catch and a second upper catch pivotably mounted on the meter housing;

a second bias element coupling the first and second upper catches to one another;

a first upper cam element and a second upper cam element in engagement with the first and second upper catches;

wherein each of the first and second upper catches and the first and second lower catches comprises a projection configured to engage an opening in the sensor strip; and

a third bias element configured to activate the first and second upper cam elements and the first and second lower cam elements to pivot, respectively, the first and second upper catches and the first and second lower catches away from the meter housing.

2. The meter of claim 1, wherein the read-head comprises an optical read-head.

3. The meter of claim 1, wherein the read-head comprises an electrochemical read-head.

4. The meter of claim 1, wherein in a first position, the first and second bias elements are configured to, respectively, pull a lower arm of the first lower catch and a lower arm of the second lower catch and a lower arm of the first upper catch and a lower arm of the second upper catch toward one another.

5. The meter of claim 1, wherein in a first position, the first and second lower cams and the first and second upper cams, in a first position thereof, are configured to push a lower arm of the first lower catch and a lower arm of the second lower catch and a lower arm of the first upper catch and a lower arm of the second upper catch, respectively, away from one another.

6. The meter of claim 1, wherein the first bias element comprises a tension spring.

7. The meter of claim 1, wherein the second bias element comprises a tension spring.

8. The meter of claim 1, wherein each of the first lower catch and the second lower catch comprises an upper arm and a lower arm.

9. The meter of claim 8, wherein the upper arm of each of the first lower catch and the second lower catch comprises the projection.

10. The meter of claim 1, wherein each of the first upper catch and the second upper catch comprises an upper arm and a lower arm.

11. The meter of claim 10, wherein the upper arm of each of the first upper catch and the second upper catch comprises the projection.

12. The meter of claim 1, wherein the third bias element couples the meter housing and the read-head.
