First Claim
1. An apparatus for engaging or disengaging a housing of an infusion device, the apparatus comprising:
- a cap having a cylindrical external surface;
a fluid conduit coupled to the cap;
a retractable detent arm formed within and defining a portion of the circumference of the cap and adapted to engage a lock recess disposed in a circular rim of the housing of the infusion device;
a first tab disposed on the cap so as to provide a first surface for a user to grip, wherein;
the first tab projects outward from the cap; and
gripping and twisting the first tab rotates the cap and engages or disengages the 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.

16. An apparatus for engaging or disengaging a housing of an infusion device, the apparatus comprising:
-
a cap; a fluid conduit coupled to the cap; a needle disposed in the cap, wherein the needle is in operable contact with the fluid conduit and pierces a septum coupled to the reservoir when the reservoir is coupled and operatively engaged with the cap; a retractable detent arm formed within and defining a portion of the circumference of the cap and adapted to engage a lock recess disposed in a circular rim of the housing of the infusion device; a first tab disposed on the cap so as to provide a first surface for a user to grip, wherein; the first tab projects outward from the cap; and gripping and twisting the first tab rotates the cap and engages or disengages the fluid medication reservoir. - View Dependent Claims (17, 18, 19)
