摘要：
Apparatus are provided for infusion devices and related operating methods. An exemplary device includes a sensing arrangement to provide an output indicative of a characteristic that is influenced by operation of the device, and a control module that is coupled to the sensing arrangement to apply a matched filter corresponding to a condition associated with the operation of the device to the output of the sensing arrangement and detect that condition based on the filtered output. In one example, the device includes a motor coupled to a plunger of a reservoir and operable to displace the plunger, wherein the characteristic is a force opposing displacement of the plunger and the control module detects an occlusion condition in a fluid path from the reservoir based on filtered force measurements.
