Abstract

The non-revseable syringe contains a plunger formed by two independent and adjacent cylindrical elements, the front being solid and the rear tubular, being closed by temporarily membrane and joined to the operating plunger by flexible flat elements. On withdrawing the plunger, both elements move together, creating a vacuum between them, and taking in the injection. When the plunger is pressed in to expel the liquid, the tubular component deforms the flexible elements, and the piston performs its working stroke. As the plunger moves towards the piston, a pointed part fixed to the front end perforates the membrane, so that the solid front element cannot be withdrawn and remains at the bottom, making a second filling impossible.
