A syringe (2), of the type having a barrel (4) with a plunger (6) disposed within the bore of the barrel, includes a needle assembly (22) housed within a needle assembly guide (14) positioned along the exterior (16) of the syringe 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. A flow path (36, 44) exists between the interior (46) of the syringe barrel and the needle assembly when the needle assembly is in the extended position. Additionally, the needle assembly can be irreversibly locked (54, 60) in the retracted position to prevent syringe reuse.
