Safety syringe

Safety syringes have a safety mechanism built into the syringe. The needle on a safety syringe can be detachable or permanently attached. On some models, a sheath is placed over the needle or the needle retracts into the barrel following injection to protect healthcare workers and others from accidental needlestick injuries. The importance of the safety syringe has increased; legislation requiring it or equivalents has been introduced in many nations since needlestick injuries and re-use prevention became the focus of governments and safety bodies.
