A Disposable syringe is intended for single use to avoid spread of contagious diseases. However syringes are reused and needle stick injuries are major cause in spreading diseases in developing countries.
A Non-Reusable Syringe assembly consists of a barrel, plunger base, plunger head , rubber cover and needle attached to the barrel. When the injection is complete, plunger head un-clips needle from the barrel and plunger base comes out of the syringe.
The design ensures the syringe can be used only once and needle can be confined in the barrel thus providing safety to persons against spread of diseases through reuse and needle sticks.
