Medication reservoir
First Claim
1. A method of connecting a cylindrical fluid medication reservoir to a medication pump housing and infusion set tubing, the method comprising releasably coupling the cylindrical fluid medication reservoir to the medication pump housing a system comprising:
- a housing engagement interface having a substantially cylindrical shape and comprising a detent arm, wherein the housing engagement interface is adapted to secure a cylindrical fluid medication reservoir within the medication pump housing,infusion tubing adapted to connect with the housing engagement interface;
a medication pump housing adapted to receive the cylindrical fluid medication reservoir, wherein;
the medication pump housing comprises a circular rim having a lock recess disposed in the rim; and
the cylindrical fluid medication reservoir is connected to the medication pump housing by rotating the housing engagement member within the medication pump housing so that the detent arm snaps into the case lock recess.

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.
