Analyte-testing instruments
First Claim
1. An instrument configured to determine the concentration of at least one analyte in a fluid, the instrument comprising:
- a display configured to display information;
a user-interface mechanism configured to allow interaction with the instrument;
a body portion including a test-sensor cartridge housed therein and an opening configured to receive a test sensor from the test-sensor cartridge;
an indexer positioned within the body portion, the indexer comprising an indexer face, a retention pin, a flexible pawl, and a user-accessible tab, the retention pin extending through a first aperture formed generally through the center of the indexer face, the indexer being configured to rotate in a first direction and a second direction about the retention pin, the flexible pawl positioned near an edge of the indexer face, the flexible pawl being configured to assist in rotating the test-sensor cartridge, the indexer face having a second aperture formed therein, the second aperture configured to be generally aligned with the test sensor; and
an excise mechanism positioned within the body portion, the excise mechanism comprising a push rod configured to extend through the second aperture and a bar coupled with and generally parallel to the push rod.

Abstract
An instrument configured to determine the concentration of at least one analyte in a fluid is disclosed. The instrument comprises a display, a user-interface mechanism, and a body portion. The body portion houses a test-sensor cartridge and includes an opening configured to receive a test sensor from the test-sensor cartridge. The body portion further includes an indexer and an excise mechanism positioned within the body portion. The indexer includes an indexer face, a retention pin, a flexible pawl, and a user-accessible tab. The indexer is configured to rotate about the retention pin, which extends through a first aperture in the indexer face. The excise mechanism includes a push rod configured to extend through a second aperture in the indexer face and a bar coupled with and generally parallel to the push rod.

13. An instrument configured to determine the concentration of at least one analyte in a fluid, the instrument comprising:
a body portion including; a display; 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; an indexer including; an indexer face having an aperture formed therein, the indexer being positioned within the body portion 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; a 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; and a user-accessible tab extending through an opening in the body portion such that the user-accessible tab may be used to rotate the indexer in the first and second directions; and an excise mechanism positioned within the body portion, the excise mechanism comprising a push rod configured to extend through the aperture of the indexer face to assist in positioning the test sensor generally aligned with the aperture into the dispensing port. - View Dependent Claims (14, 15, 16, 17, 18)
