RESERVOIR CONNECTOR
First Claim
1. A system for connecting a fluid medication reservoir to a medication pump housing, comprising:
- a housing engagement interface adapted to be inserted into a corresponding opening in the medication pump housing;
an external needle disposed at and extending outwards from a first end of the housing engagement interface, wherein the needle is adapted to draw fluid from a supply vial;
a housing engagement member disposed on the exterior of the housing engagement interface, wherein the housing engagement member is adapted to engage the medication pump housing;
a first tab disposed at the first end of the housing engagement interface so as to provide a first surface for a user to grip and twist the housing engagement interface to rotatably engage or disengage the housing engagement member within the opening of the medication pump housing, wherein the housing engagement interface is configured to at least partially fit inside the opening of the medication pump housing; and
a cylindrical fluid medication reservoir disposed at a second end of the housing engagement interface to store the fluid drawn from the supply vial, wherein the housing engagement member is disposed on the housing engagement interface so that the cylindrical fluid medication reservoir is disposed within the opening of the medication pump housing when the housing engagement interface is operatively engaged with the medication pump housing.

Abstract
A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. A base is provided which is adapted to receive a reservoir. The base has a base engagement member, such as a detent, projecting therefrom. A cap is provided which is adapted to receive the base. The cap includes a first cap engagement member, such as a detent opening, which is adapted to removably engage the base detent. The cap further includes a second cap detent opening which is adapted to removably engage the base detent. A piercing member, such as a needle, is disposed in the interior of the cap in such a manner that the needle is separated from the reservoir septum when the base detent is in the first cap detent opening, and the needle pierces the reservoir septum when the base detent is in the second cap detent opening. When the reservoir, the base and the cap are connected to form an integrated unit, this unit is then capable of being inserted and secured in the infusion pump housing.
