Abstract

Safety syringe with a needle which automatically disappears after use, and is prevented from re-emerging, so as to prevent the re-use thereof. The needle is integral with a bushing and is initially fitted into a ring with an off-centre hole, which moves inside a spring, which is kept compressed during the liquid aspiration phase by projecting elements of the bushing which are inserted into an annular groove inside the barrel, so that, when the spring is no longer retained by the aforesaid stop, it quickly pushes the bushing with the needle backwards, making the projecting elements go beyond the groove, withdrawing the needle from the ring with the off-centre hole and locking the needle inside the barrel. <IMAGE>
