ABSTRACT:
Disclosed is a pistol-type syringe for injecting the contents of an ampoule or the like by means of an axial displaceable piston. The syringe includes a handle member with a generally flat frontal surface having a bore through which an axially displaceable plunger member is positioned. The ampoule or the like is held in a position coaxial with the plunger. The plunger is provided with a generally disk-shaped pressure piece which is slidable along the plunger and which has a rest position defined by the flat frontal surface of the handle member. The handle member also has an associated activating lever which is operable to exert a force on the pressure piece.
