Abstract
A safety syringe is disclosed. The syringe includes a syringe barrel, a plunger, a needle, a needle sleeve, and a pushrod. At one of the pushrod is attached to the needle sleeve while the other end of the pushrod protrudes slightly into the needle end of the syringe barrel. When the injection is administered to the patient, the plunger travels all the way to the needle end of the syringe barrel. The plunger contacts the pushrod which causes the sleeve to cover the needle point automatically as the injection is given.
