First Claim
Patent Images
1. An indexer configured to index a test-sensor cartridge, the indexer comprising:
- an indexer face having a first aperture formed generally through the center thereof and a second aperture configured to generally align with a test-sensor cavity of the test-sensor cartridge;
a retention pin extending through the first aperture;
a flexible pawl positioned near and coupled with an edge of the indexer face; and
wherein the indexer is adapted to be rotated in a first direction and a second generally opposite direction about the retention pin, the flexible pawl being configured to bend about a circumference of the test-sensor cartridge when the indexer is rotated in the second direction, the flexible pawl being configured to assist in rotating the test-sensor cartridge.

Abstract
An indexer adapted to index a test sensor from a test-sensor cartridge. The indexer includes an indexer face having a first aperture formed generally through the center thereof. The indexer further includes a retention pin extending through the first aperture and a flexible pawl positioned near an edge of the indexer face. The indexer is adapted to be rotated in a first direction and a second generally opposite direction about the retention pin. The flexible pawl is configured to bend when the indexer is rotated in the second direction. The flexible pawl is configured to assist in rotating the test-sensor cartridge.

15. An instrument configured to determine the concentration of at least one analyte in a fluid, the instrument comprising:
-
a body portion including; a display, and a user-interface mechanism; a test-sensor cartridge housed within the body portion, the test-sensor cartridge including a plurality of test-sensor cavities formed therein, each of the plurality of test-sensor cavities including a test sensor housed therein, and a plurality of generally uniformly-spaced notches positioned along an edge of a first end of the test-sensor cartridge, each of the plurality of notches corresponding with a respective one of the plurality of test-sensor cavities; a dispensing port for receiving a test sensor from the test-sensor cartridge; and an indexer including an indexer face having an aperture formed therein, the indexer being positioned such that the indexer face is generally adjacent to the first end of the test-sensor cartridge and the aperture is generally aligned with one of the test sensors of the test-sensor cartridge, and a flexible pawl positioned near and coupled with an edge of the indexer face, the flexible pawl configured to engage with a first notch of the test-sensor cartridge when the test-sensor cartridge is rotated in a first direction and configured to disengage from the first notch when the test-sensor cartridge is rotated in a second direction, wherein the flexible pawl is configured to assist in rotating the test-sensor cartridge. - View Dependent Claims (16, 17, 18, 19, 20)
