    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: Systems for managing pressure in a fluid reservoir chamber of a fluid infusion device are provided. For example, a fluid infusion device comprises a housing having a reservoir chamber that receives a fluid reservoir and a pump chamber. The fluid infusion device also includes a drive system contained within the pump chamber, and the drive system includes a slide that is movable relative to the fluid reservoir. The slide includes a proximal slide end that cooperates with a portion of the fluid reservoir to dispense fluid, and the proximal slide end has a projection. The fluid infusion device includes a pressure management system defined in the projection of the slide. The pressure management system includes at least one bore defined through the projection. The at least one bore is spaced a distance apart from a perimeter of the projection to vent air from the reservoir chamber into the pump chamber.

    Abstract: Apparatus are provided for infusion devices and related control systems and methods. In one embodiment, an infusion device includes a voided portion adapted to receive a shaft portion that includes a shaft coupled to a plunger of a reservoir. The shaft portion includes a detectable feature having an optically detectable pattern such as gray code, and the infusion device includes a sensing arrangement having an optical sensor proximate the voided portion to sense the detectable feature. In some embodiments, a control module is coupled to the sensing arrangement to determine a remaining amount of fluid in the reservoir based at least in part on the sensed position of the detectable feature. In embodiments, the optical sensor detects the sensed position of the shaft based on the detectable feature only when the reservoir is replaced and/or after each delivery of fluid to reduce power consumption.

    Abstract: A fluid infusion device and related operating methods are disclosed. The fluid infusion device has a housing, a fluid pump mechanism, a transcutaneous conduit assembly having a fluid conduit coupled to the pump mechanism, and an insertion mechanism for inserting the conduit into the body. An exemplary method begins by detecting a first installation of a fluid cartridge module in the housing, wherein the detecting occurs after the housing has been affixed to the body. In response to the detecting, the operating method automatically activates the insertion mechanism to insert the fluid conduit into the body.
