    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. The stator includes a cam element having a stator cam surface. The cam elements cooperate to axially displace the rotor as a function of rotation. A biasing element provides force to urge the cam elements together. A drive motor is coupled to actuate the rotor to pump medication fluid from a fluid cartridge module to a body, via a subcutaneous conduit. A force sensor is coupled to the rotor to generate output levels in response to force imparted thereto. The force sensor cooperates with a detection circuit that obtains and processes the output levels to detect occlusions in a fluid path downstream of the fluid pump mechanism.

    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.

    Abstract: An infusion set for use with a fluid infusion device having a fluid reservoir includes a cannula that provides a fluid flow path and a first housing. The first housing includes an articulation member coupled to the cannula. The articulation member is pivotable relative to the first housing to move the cannula relative to the first housing. The first housing is coupled to a fluid supply line to provide a fluid to the cannula, and the fluid supply line is to be coupled to the fluid reservoir to receive the fluid. The infusion set includes a second housing uncoupled from the first housing that surrounds the first housing and receives a portion of the fluid supply line.

    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.
