Abstract

Injectable syringe equipped with a liquid outlet perforator characterized essentially by the fact that the ampoule, which can be used once only, is conveniently provided with a plunger without a soft rubber rod and with a stopper-seal of plastic material disposed at one end the ampule having at the opposite end a soft rubber disc blocked by a riveted metal envelope that also extends axially forming a nozzle in which a rubber perforator tube is housed at the appropriate time, this nozzle and its inner piercing tube being protected with a cap of plastic material plugged into that end of the ampule, provision is also made for the injection of the liquid a stem also made of plastic material that is screwed into said plunger of the ampule, this stem also having end fins to facilitate the finger tightening as well as an internal accommodation with a protective cap in which the hypodermic needle conveniently fixed by its neck can be stored, with the particularity that the perforation of the rubber disc of the ampoule takes place automatically when the hypodermic needle is coupled in the mouthpiece since the pressure itself to verify the coupling moves the drilling tube inwards, its tip being introduced into the liquid, in a condition to pass it completely aseptically to the needle at the moment of injection.
