Abstract: A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.

Abstract: 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.

Abstract: Systems and methods for alignment and detection of a consumable component are disclosed herein. For example, a method for determining if a consumable component is coupled to a durable component to enable dispersion of a medicine is provided. The method includes determining if a signal from an electrical contact coupled to a durable component has changed an electrical state, and comparing the signal to a reference signal from a second electrical component coupled to the durable component. The method includes sampling a sensor coupled to the durable component to acquire sensor data indicative of a magnetic field observed by the sensor, and outputting data that a consumable component is coupled to the durable component if the signal is different than the reference signal, and the sensor data is within an acceptable range.
