Abstract: A device for delivering fluid to a user includes a housing, a drive motor assembly in the housing, a force sensor, and an electronics module. The drive motor assembly regulates delivery of fluid by actuating a piston of a fluid reservoir, and the force sensor generates output levels in response to force imparted thereto during, for example, fluid delivery operations. The electronics module processes the output levels of the force sensor to assess the operating health of the force sensor, to check for occlusions in the fluid delivery path, and to monitor the seating status of the fluid reservoir.

Abstract: A fluid infusion device and related operating methods are presented here. An exemplary embodiment of the device includes a drive motor assembly, a force sensor associated with the drive motor assembly, and a reservoir cavity that accommodates fluid reservoirs. An exemplary operating method for the device obtains force measurements for a reservoir seating action of the drive motor assembly, where the force measurements indicate measures of force imparted to the force sensor during the reservoir seating action. The method continues by determining that a vent in the reservoir cavity is blocked, based on an analysis of the force measurements, and by initiating corrective action for the fluid infusion device in response to determining that the vent in the reservoir cavity is blocked.
