ABSTRACT:
A syringe (2), of the type having a barrel (4) with a plunger (6) disposed within the bore of the barrel, includes two needle assemblies (22) housed within needle assembly guides (14) positioned along the exterior (16) of the syringe barrel. Each 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 each needle assembly when each needle assembly is in the extended position. The use of two needles allows one needle to be used to aspirate the liquid pharmaceutical into the syringe and the other, unused needle to be used to give the injection. Each needle assembly is irreversibly locked (54, 60) when moved into the retracted position to prevent syringe reuse.
