摘要：A safety syringe device with separable needle stem by turning back includes a syringe tube, a push rod, a needle seat, a needle stem and a needle cap. The needle stem is attached to a bushing which is fitted to a core bit thereby fixing the needle seat at its
position. The syringe tube and the needle seat that is screw combined are further tightly settled by dexterous positioning means. After finishing syringe, the needle sheet along with the needle stem is withdrawn and hidden in the syringe tube, the push rod can be broken at its brittle neck portion by tapping it against a breaking fringe formed around the syringe tube thereby leaving the needle seat and needle stem inside the syringe tube. By doing so, the used needle stem will never emerge out accidentally to puncture people's skin. The used syringe tube, push rod, needle seat and stem can be thrown away altogether to avoid restoring for reuse.
