Abstract
A safety syringe has a hollow barrel, a needle hub and a plunger. The hollow barrel has a distal end, a proximal end, a cone-shaped end formed on the proximal end with an opening. The plunger has a proximal end and a needle retractor formed on the proximal end. The needle hub with a needle is detachably mounted inside the proximal end of the hollow barrel and has an axial fitting to engage the plunger. When the safety syringe is used, the plunger connects to the needle hub and is pulled toward the distal end of the hollow barrel to draw the needle hub with the needle inside the hollow barrel to keep people from being hurt or infected by an exposed needle.
