Needle changing apparatus
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 needle holder disposed within the housing, for fluidly connecting with a medicament container of the medicament delivery device;
a plurality of needles displaceably disposed on the needle holder;
a user interface disposed on the housing to individually select one of the plurality of needles and displace the 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.

4. A combination, comprising:
-
a medicament delivery device having a medicament container; and an apparatus for storing and changing needles, the apparatus being connectable with the medicament delivery device, the apparatus comprising; a housing having a floor disposed at a distal end thereof, and a having a reservoir disposed therein, the reservoir being fluidly connected with the medicament container when the apparatus is connected with the medicament delivery device; a needle holder disposed within the housing, for fluidly connecting with the medicament container of the medicament delivery device; a plurality of needles displaceably disposed on the needle holder; a user interface disposed on the housing to individually select one of the plurality of needles and displace the 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 boot disposed at a distal end of the patient portion of the needle. - View Dependent Claims (5)

6. 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 needle holder disposed within the housing, for fluidly connecting with a medicament container of the medicament delivery device; a plurality of needles displaceably disposed on the needle holder; a user interface disposed on the housing to individually select one of the plurality of needles and displace the 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 boot disposed at a distal end of the patient portion of the needle; 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 boot is adapted to slide relative to the introducer, the boot having a sterile floor at a distal end thereof; wherein the introducer has a distal cutting tip adapted to cut a portion of the sterile floor, and a proximal shoulder adapted to engage the boot; wherein each sterility barrier is adapted such that during distal displacement of the needle, subsequent to contact between the boot and the floor of the housing, the introducer distally displaces relative to the boot and cuts the sterile floor; and wherein each sterility barrier is adapted such that subsequent to engagement between the proximal shoulder and the boot, 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.
