Cocking and advancing mechanism for analyte testing device
First Claim
1. An analyte testing device, comprising:
- a housing that houses an analyte sensor and a lancet;
a linkage mechanism at least partially disposed in the housing and having a first link coupled with the analyte sensor and a second link coupled with the lancet, wherein the first and the second links intersect one another at an angle on the linkage mechanism;
an actuator coupled with the linkage mechanism; and
wherein a single motion of the actuator in one direction moves (a) the first link and thereby exposes the analyte sensor at a first position of the housing, and (b) the second link and thereby advances the lancet for projection from a second position of the housing; and
wherein the analyte sensor and the lancet are configured to move independently of each other.

Abstract
An analyte testing device includes an analyte sensor, a lancet, and a mechanism with an actuator that operates to independently expose the analyte sensor and advance the lancet into position for use. The analyte sensor is preferably included in an analyte sensor cartridge that houses a plurality of sensors. Similarly, the lancet is preferably included in a lancet cartridge that houses a plurality of lancets. The actuator can be a lever configured to expose the analyte sensor and advance the lancet into position with a single motion (e.g., pulling the lever). The actuator also preferably operates to cock a hammer in preparation for lancing a body member to draw a blood sample. The mechanism can be a linkage coupled with the actuator and configured to engage the analyte sensor and lancet.
