ABSTRACT:
A medical syringe has a needle shoot back mechanism which can be triggered to shoot the used needle back into the safety of the syringe body and is of a special design to allow the needle to be replaced without affecting the efficiency of the shoot back mechanism. A rotatable cover member is also available which is relatively large and which can be more easily gripped and turned to remove the needle from the syringe.
