摘要 |
A safety syringe includes: a hollow needle assembly having a hollow needle portion detachably coupled to a shank portion embedded in a sleeve portion of a syringe and having a needle head portion formed on a rear portion of the shank portion, and a plunger slidably held in the syringe and having a biasing socket recessed in the plunger for engaging the needle head portion of the needle assembly for a coupling of the needle assembly with the plunger for a retraction into the syringe for obliquely biasing the needle portion for preventing re-protrusion of the needle outwardly, thereby allowing a variety of needles of different sizes to be replaceably mounted on the shank portion outside the syringe for a convenient mounting of the needle on the syringe. |
