Abstract
Apparatus are provided for infusion devices and related control systems and methods. An infusion device includes a voided portion adapted to receive a shaft portion that includes a shaft coupled to a plunger of a reservoir and a sensing arrangement proximate the voided portion to sense a detectable feature. A control module may determine a remaining amount of fluid in the reservoir or identify an anomalous condition based at least in part on the sensed position of the detectable feature.
