ABSTRACT:
A pre-filled syringe is provided with a retractile needle. The needle end of a syringe is enclosed in a sterile chamber within a casing sealed by a cap with a break-off tip. The barrel of the syringe is movable within the casing from a remote pre-injection position to a forward injection position and back again. When the barrel is moved forward a first end of the needle passes through the opening of the cap and then the opposite end comes in contact with the injectant. When the barrel is withdrawn to a pre-injection position, the needle is retracted within the casing and is prevented from re-entering the opening in the cap.
