    • A retractable safety syringe may comprise a needle, needle holder, syringe body, and a plunger. A proximal portion of the body and a piston of the plunger may define a variable vacuum compartment. A through hole pneumatically connecting ambient air and the variable vacuum compartment may be formed through a thumb platform and rigid shaft of the plunger for allowing air to escape out of the variable vacuum compartment when a piston of the plunger is traversed toward the retracted position and allow air to be introduced into the variable vacuum compartment when the piston is traversed toward the engaged position. A retraction force may be created by the variable vacuum compartment by covering an entrance of the through hole and traversing the piston to the engaged position. At the engaged position, the piston may engage the needle holder and the retraction force may retract the piston, needle holder and needle into the syringe body to prevent accidental needle pricking and needle reuse.
    • 可伸缩的安全注射器可以包括针,针保持器,注射器主体和柱塞。 主体的近端部分和柱塞的活塞可以限定可变的真空室。 气动连接环境空气和可变真空隔室的通孔可以通过拇指平台和柱塞的刚性轴形成,用于当柱塞的活塞朝向缩回位置移动时允许空气从可变真空室中逸出,并允许 当活塞朝向接合位置移动时,被引入可变真空室的空气。 通过覆盖通孔的入口并将活塞穿过接合位置,可由可变真空隔室产生回缩力。 在接合位置,活塞可以接合针保持器,并且缩回力可以将活塞,针保持器和针缩回到注射器体中,以防止意外的针刺和针重复使用。
