Abstract

The liq. in the syringe is pushed towards the hollow needle by a first piston which, in turn, is actuated by a second piston. The latter is operated by a gas under press. when an injection is made. For easy handling, the syringe is in the form of a pistol with a hollow cylinder which is screwed into the body after the insertion of a cartridge which takes the form of a glass tube filled with the medicament to be injected. This tube is closed by two stoppers, one carrying the injection needle and the other acting as the first piston, which slides in the tube when pushed by a rod attached to the second piston which is operated by compressed air from a cylinder when the trigger is pressed. The injection press. can be easily regulated and stopped instantaneously thus avoiding the projection of liq. when the needle is withdrawn from the patient.
