Abstract

The self-disposable syringe is characterized by comprising a combination of recesses and projections between its body and plunger which cause engagement between both members on completion of the injection, while an axial stud emerging from the internal end of the plunger and penetrating into a chamber, with a defining necklace, established in the head of the needle, by its length which is slightly greater than that of the chamber, causes breakage of the plunger and, by the traction of an elastic element located inside the plunger, breakage also of the head of the needle, by means of weakened crowns provided for the purpose, causing the used needle to be placed completely into the internal cylinder of the body of the plunger.
