<p>A syringe (70), of the type having an adapter (76) housing a pharmaceutical-filled container (72) with a plunger (82, 86) disposed within the bore of the container barrel (74), includes a needle assembly (100) housed within a needle assembly guide (98) positioned along the exterior of the barrel. The needle assembly guide provides a path along which the needle assembly moves, between an extended position, with the needle exposed, and a retracted position, with the needle encompassed by the needle guide. The adapter includes a hollow spike (88) which pierces the septum (78) of the container to create a flow path (88, 104, 44) between the interior of the container and the needle assembly when the needle assembly is in the extended position. The needle assembly can be irreversibly locked (54, 60) in the retracted position to prevent syringe reuse.</p> |
