Abstract
Infusion devices, systems, and related operating methods are provided. A method of detecting an occlusion in a fluid path involves a control module of an infusion device operating a driver module to provide energy to an actuation arrangement to achieve a commanded actuation state, wherein the actuation arrangement is coupled to a plunger configured to deliver fluid via the fluid path, obtaining a measured actuation state of the actuation arrangement via a sensing arrangement, and detecting an occlusion condition based on a relationship between the commanded actuation state and the measured actuation state.
