Abstract
A disposable syringe where the needle, after injection, retracts permanently into a safe position within the syringe.The syringe has a needle-holder removably inserted in a hollow spout fixed to the tubular barrel where the plunger and piston move in the syringe.The needle-holder is kept in the spout by stops means which can be broken by the piston.The needle-holder and the piston are provided with reciprocal attaching means which join together at the end of the piston injection run, at the same time the stop means are broken. After this, the piston is automatically drawn back, taking with it the needle-holder and the needle linked to it until the latter enters entirely into the barrel of the syringe.
