First Claim
1. An apparatus for storing and changing needles for connection with a medicament delivery device, the apparatus comprising:
- a housing having a floor disposed at a distal end thereof;
a plurality of needles displaceably disposed within the housing;
a user interface disposed on the housing to displace a selected needle; and
a plurality of sterility barriers for ensuring sterility of a patient portion of each needle prior to exposure to an outside of the apparatus;
wherein each sterility barrier comprises;
a needle hub disposed around a portion of the patient portion of the needle; and
an introducer, adapted to slide relative to the needle hub, the introducer having a distal cutting tip adapted to cut an opening to access the outside of the apparatus through the floor.

Abstract
An apparatus is disclosed for storing and changing needles for connection with a medicament delivery device, comprising an inner housing, a reservoir disposed within the inner housing, and a needle holder disposed within the inner housing, for fluidly connecting a medicament container of the medicament delivery device with the reservoir. The apparatus also includes a plurality of patient needles displaceably disposed on the needle holder, and an outer housing displaceably disposed about the inner housing and providing a user interface to individually select one of the plurality of patient needles, connect the selected needle with the reservoir, expose the selected needle outside of the apparatus for injection, and store the selected needle.

8. An apparatus for storing and changing needles for connection with a medicament delivery device, the apparatus comprising:
-
a housing; a plurality of patient needles displaceably disposed in the housing; a user interface disposed on the housing to individually select one of the plurality of patient needles; and a sterility barrier for ensuring sterility of a patient portion of each needle prior to exposure to an outside of the apparatus; wherein the sterility barrier comprises; a sterile floor disposed at a distal end of the housing; a needle hub disposed around a portion of the patient portion of the needle; and an introducer, slidable relative to the needle hub; wherein the introducer has a distal cutting tip for cutting a portion of the sterile floor, and a proximal shoulder for engaging the sterile floor subsequent to cutting the sterile floor; and wherein subsequent to engagement between the proximal shoulder and the sterile floor, further distal displacement of the needle distally displaces the needle hub relative to the introducer and exposes an end of the patient portion to the outside of the apparatus.
