发明名称 SPRING CLIP SAFETY IV CATHETER
摘要 A safety IV catheter includes a unitary, resilient needle guard received in a catheter hub. The needle guard includes a proximal arm or wall that includes an opening through which a needle passes for axial movement. When the needle is retracted from the catheter, it releases the force that had previously prevented movement of the needle guard within the catheter hub. This in turn causes the needle guard to snap into a position in which it is clamped onto the needle shaft and in which its distal wall blocks access to the needle tip. In this condition, the spring needle guard and needle can be removed from the catheter hub. A slot or crimp may be formed in the needle shaft that engages with the needle guard after the protected needle and needle guard are removed from the catheter hub, thereby to prevent removal of the protected needle from the needle guard.

主权项 1. A safety catheter assembly comprising: a needle attached to a needle hub, said needle comprising a needle shaft having a sharpened needle tip; a catheter hub having a catheter tube attached thereto and having the needle located in the catheter tube in a ready position; a needle protector clip positioned adjacent to the needle shaft of the needle, said needle protector clip comprising a first resilient arm having a first arm length and a first wall comprising a first planar surface extending from the first arm length with the first planar surface being oriented transversely to the first arm length and a second resilient arm having a second arm length and a second wall comprising a second planar surface extending from the second arm length with the second planar surface being oriented transversely to the second arm length; and wherein the first resilient arm the second resilient arm intersect in the ready position and in a protective position, in which the first wall and second wall overlap to block the sharpened needle tip.
