1. An apparatus for storing and changing needles for a medicament delivery device having a medicament container, the apparatus comprising:
a fixed mount adapted to connect the apparatus with the medicament delivery device; a needle holder displaceable along a circuitous path and connecting a plurality of needles displaceably disposed thereon; a guide member adapted to guide displacement of the needle holder, the guide member being disposed about the fixed mount; a user interface rotatably disposed about the fixed mount and having at least one internal engaging structure adapted to displace the needle holder along the circuitous path; and a fixed post connected with the fixed mount adapted to guide the needle holder toward an activated position; wherein the user interface is rotated to displace the needle holder along the circuitous path and position a selected needle in the activated position; wherein the guide member comprises a stabilizing member adapted to position the selected needle in the activated position; and wherein the fixed post comprises a lock feature adapted to selectively engage a lock ring displaceably disposed on the selected needle, to selectively prevent rotation of the user interface and displacement of the needle holder subsequent to the needle being positioned in the activated position.
