Abstract

Hypodermic syringe has a needle (8) attached at the top to a plate (19). It is supplied with the needle inside and when the piston (11) is depressed it presses on the plate and advances the needle to the position of use, when the plate locks against studs (15) on the inner wall of the syringe.
