Abstract
This invention is a hypodermic needle that cannot be reused after the first injection. The syringe (1) has a component that does not allow the plunger system (3) to reopen - when the plunger (4) is in the position right before being completely inserted into the tube (2). In fact only in these conditions the flexible layer, is mechanically resistant (5) (the distal end of which is fixed to the internal wall of the tube), once the plunger has completed its course and at the end of the injection - after the safety is broken (7) and the transfer of the cylinder blister (6) by the plunger towards the inside - it goes into a busy position that stops the return of the piston - plunger system. The layer (5) and the blister (6) never make contact with the liquid being injected.
