    Abstract: An embodiment of a fluid infusion device includes a fluid pump mechanism having a rotor and a stator. The rotor includes a reference surface and a cam element rising from the reference surface, and the stator includes a cam element having a stator cam surface. The cam elements cooperate to axially displace the rotor as a function of angular position of the rotor. A biasing element provides force to urge the cam elements together. A drive motor actuates the rotor to pump medication fluid from a fluid cartridge module to a body, via a subcutaneous conduit. A detection circuit processes axial and angular position data of the rotor, and determines that an upstream occlusion has occurred based on detectable characteristics of the axial and angular position data.

    Abstract: Apparatus are provided for infusion devices and related control systems and methods. In one embodiment, an infusion device includes a voided portion adapted to receive a shaft portion that includes a shaft coupled to a plunger of a reservoir. The shaft portion includes a detectable feature, and the infusion device includes a sensing arrangement proximate the voided portion to sense the detectable feature. In some embodiments, a control module is coupled to the sensing arrangement to determine a remaining amount of fluid in the reservoir based at least in part on the sensed position of the detectable feature. In other embodiments, the control module identifies an anomalous condition based at least in part on the sensed position of the detectable feature.

    Abstract: The fluid infusion system is disclosed that includes a pump housing that has a reservoir cavity and is designed to be pocketable. The reservoir cavity has a rim and helical coupling features formed on an interior face of the reservoir cavity. The fluid infusion system further has a reservoir that is removable from the reservoir cavity and the reservoir also has an open end. A removable cap coupled to the pump housing is also included in the fluid infusion system. The cap has corresponding coupling features, an exterior surface and a tab. The corresponding coupling features are defined to couple the cap to the pump housing while the tab is defined as a ridge that extends away from the exterior surface. The tab further has a port to accommodate fluid flow from the reservoir where the port defines an axis of rotation such that torque applied to the tab about the axis of rotation disengages the coupling between the cap and the pump housing. Further included in the infusion system is a guard that is removably coupled to the pump housing. The guard has a slot defined to immobilize rotation of the tab about the axis of rotation.
