Smart connection interface

摘要

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.

主权项

1. An infusion pump system, comprising:
an infusion pump device having a reservoir receptacle to receive a reservoir containing infusion media and to selectively dispense the infusion media from the reservoir when the reservoir is received within the reservoir receptacle; the reservoir for containing the infusion media; at least one sensor element held by the infusion pump device; a connector interface to connect the reservoir with the infusion pump device, the connector interface comprising a cap to connect to the reservoir to form a reservoir/cap unit; and at least one magnetic detectable feature arranged on the cap for detection by the at least one sensor element on the infusion pump device when the reservoir of the reservoir/cap unit is received in the reservoir receptacle of the infusion pump device, wherein the at least one magnetic detectable feature comprises a magnetic field angle of a magnet that is attached to a housing of the cap, the magnetic field angle being an angle of orientation of a magnetic field of the magnet relative to a predefined axis of the cap or the reservoir/cap unit, the magnetic field angle being non-parallel and non-perpendicular to the predefined axis; wherein the magnetic field angle of the at least one magnetic detectable feature is at least one detectable parameter that is associated with one or more characteristics of the cap, the reservoir, a cannula, or a tubing connected between the cap and the cannula; and wherein one or more predefined characteristics of the cap, the reservoir, the cannula, or the tubing connected between the cap and the cannula comprises a type or identity of a manufacturer of the cap, the reservoir, the cannula or the tubing, or a size of the cap, the reservoir, the cannula or the tubing.
