    • A needle tip spring protector for a needle having a proximal end, a distal end, and a shaft extending therebetween. The needle tip spring protector includes a spring that circumferentially surrounds a portion of the needle shaft and is restrained in a state wherein its inner diameter is large enough to allow the shaft to move freely within the spring. When the needle is moved to a position in which its distal end is at least partly within the spring, at least one of the ends of the spring releases from restraint such that the spring automatically returns to a state in which its inner diameter is sized so as to grippingly engage the shaft of the needle. Thus, after activation, the spring securely surrounds the distal end of the needle to protect healthcare workers and others from accidental contact with the needle's distal end. When used in conjunction with a catheter assembly, the needle tip spring protector may passively release from the catheter hub after the spring is automatically activated.
    • 用于针头的针尖弹簧保护器,其具有近端,远端以及在其间延伸的轴。 针尖弹簧保护器包括周向围绕针轴的一部分并被限制在其内径足够大以允许轴在弹簧内自由移动的状态的弹簧。 当针被移动到其远端至少部分地在弹簧内的位置时,弹簧的至少一个端部从约束件释放,使得弹簧自动返回到其内径的尺寸如此大小的状态 以夹紧地接合针的轴。 因此,在激活之后,弹簧牢固地围绕针的远端,以保护医护人员和其他人免于与针的远端意外接触。 当与导管组件结合使用时,在弹簧自动启动之后,针尖弹簧保护器可以从导管套管被动释放。
