MONITORING THE SEATING STATUS OF A FLUID RESERVOIR IN A FLUID INFUSION DEVICE
First Claim
Patent Images
1. A device for delivering fluid to a user, the device comprising:
- a housing;
a reservoir cavity within the housing to accommodate fluid reservoirs;
a drive motor assembly in the housing to regulate delivery of fluid by actuating a piston of a fluid reservoir;
a force sensor associated with the drive motor assembly to generate output levels in response to force imparted thereto; and
an electronics module coupled to the force sensor to process the output levels to determine a seating status of the fluid reservoir in the reservoir cavity.

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.
