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: Apparatus are provided for infusion devices and related systems and operating methods. An exemplary system includes a motor, a sensing arrangement coupled to the motor to provide output indicative of a detected characteristic of the motor when the sensing arrangement is enabled, and a module coupled to the sensing arrangement to periodically enable the sensing arrangement while the motor is idle and detect potential unintended motion of the motor based on the output from the sensing arrangement while periodically enabling the sensing arrangement. In some embodiments, the motor includes a rotor configured such that its rotation provides translational displacement of a plunger in a fluid reservoir, and the sensing arrangement includes one or more sensors configured to provide output indicative of a detected magnetic field of the rotor magnet.

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.

Abstract: Fluid infusion systems such as a portable fluid infusion device includes a housing configured to accommodate a removable fluid reservoir. The housing has a largest dimension and a smallest dimension. The portable fluid infusion device includes a drive system configured to be serially coupled to the removable fluid reservoir such that a combined dimension of the drive system and the removable fluid reservoir is less than or equal to the largest dimension. The portable fluid infusion device includes a planar battery configured to supply power to the drive system. The planar battery has a plurality of faces comprising one or more faces having a largest area, and the planar battery being situated such that the one or more faces are parallel to the largest dimension and the smallest dimension.
