Safety syringe

Abstract

A safety syringe includes: a barrel, a plunger, a connecting member and a cover cap. Said barrel has a barrel tip with an injection passage at said barrel top. A plunger holds in said barrel. A connecting member covers over said barrel, embedded on said barrel tip. Said front part of connecting member forms at least a tab coupling with a extending a coupling shield in facing front to said tab coupling. Said connecting member has at least a coupling member and a seat bearing force from an elasticity element. At said connecting member top part has a locking wherein install a connected tip linked to said injection passage. A cover is capping said connecting member comprising a L-form socket which providing a socket path and a groove of said coupling member and tab coupling for coupling and fixing. A tuber front locates at the front part of said cover cap on which interior side bears force from elasticity element. Finally, as the above designed, such syringe device achieves the safety of after-use-syringe.
