ELECTROCHEMICAL SENSOR MODULE
First Claim
1. A sensor cartridge element comprising:
- a sensor module extending from a proximal end to a distal end, the sensor module including an analysis cell housing, a skin piercing member, and a skin piercing member anchor to which the skin piercing member is secured, the analysis cell housing defining an analysis cell and a sample passageway leading from the distal end of the sensor module to the analysis cell;
an electrode arrangement installed on the sensor module and arranged at least partially within the analysis cell of the sensor module, the electrode arrangement being configured to generate an electrical signal when exposed to a fluid sample collected in the analysis cell;
a delivery arrangement securely coupled to the sensor module, the delivery arrangement including a drug reservoir, a piston chamber, and a valve arrangement providing selective fluid communication between the drug reservoir and the piston chamber.

Abstract
Certain embodiments of a sensor cartridge element include a sensor module, an electrode arrangement installed on the sensor module, and a delivery arrangement securely coupled to the sensor module. The sensor module includes an analysis cell and a skin piercing member. The electrode arrangement generates an electrical signal when exposed to a fluid sample collected in the analysis cell. The delivery arrangement includes a drug reservoir, a piston chamber, and a valve arrangement providing selective fluid communication between the drug reservoir and the piston chamber. Metering electronics and an actuator can manage collection of fluid samples and/or dispensing of drug doses.
