A group of designers at the Vaal University of Technology, William Blake, Paul Lambourn, Jose loureiro, Michael Moore, David Shiel, Mirko Tappero, Henk van der Meyden and Alexis Wadman invented the Smartlock safety syringe.
The Smartlock Safety Syringe is a three-piece single-use syringe which has 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. The syringes were developed in 1999 and provide improved protection against needlestick injury and contamination by diseases such as Ebola virus, Hepatitis and HIV.
