Abstract

The invention concerns a single use syringe that comprises a hollow piston covered at the top with a flexible membrane and sliding inside a tubular body. The bottom of the cylindrical body has an axially open projection and means for locking a needle projecting outside it. There is a cutting device to tear the membrane working in conjunction with a spring to cause the needle, when released by the locking device by means of a thrust at the end of the stroke of the piston, to enter the piston. The syringe is characterised by the fact that the needle projects inside the cylindrical body and is fitted with means for attaching it, with the thrusting motion of the piston, to a projection inside the membrane. Located in the piston, the spring is connected to the same internal projection of the membrane. The cutting device surrounds the projecting part of the needle in the cylindrical body and operates on the internal projection of the membrane. <IMAGE>
