Abstract

Disclosed is a medical device component for delivering medication fluid to a patient. The medical device component includes a fluid infusion device to regulate delivery of medication fluid, a body-mountable base unit, and a top cover assembly that is removably couplable to the base unit and to the fluid infusion device. The base unit includes a cannula to deliver medication fluid under the control of the fluid infusion device, and a physiological analyte sensor to measure a physiological characteristic. The base unit also includes an electronics assembly electrically connected to sensor leads to obtain measurements in the analog domain, to convert measurements into digital sensor data, and to communicate conditioned digital sensor data to the fluid infusion device. The top cover assembly is configured to provide both fluid and electrical connections for the base unit, by way of an infusion tube having sensor conductors integrated therein or otherwise associated therewith.
