ABSTRACT:
A universal syringe includes a sterile filled glass vial of injectable medicament retained within the vial by identical piston seals disposed proximate each cylinder end. The piston seals are in intimate frictional contact with the internal walls of the vial and are slidable therealong. Removable plastic end caps are removably retained on the vial ends to maintain the vial in a sterile condition until used. A slidable finger rest encompassing the outer wall of the vial is movable therealong and retained by externally protruding lip portions provided on both ends of the vial. A needle assembly is removably retained in a hollow cylindrically shaped piston rod which is capped on both ends to maintain the sterile condition. The needle assembly may be readily removed from the hollow piston rod and one end thereof may be inserted into the vial piston seal at either end and retained thereby, a needle pierced the seal to provide communication of the medicament in the vial through the needle opening to the patient. The piston rod may be inserted into the remaining vial seal and be retained thereby, thus providing a complete syringe.
