    摘要： A needle guard includes a clip with a canting wall to grip the needle shaft and a distal wall to block the tip thereof, wherein the canting and distal walls may be interconnected by an angled strut, a spring member, such as a leaf spring, may have a portion extending past an edge of the strut to bias the clip to grip the needle shaft, and the distal wall may be or include a stylus and have an L-shape to define a lip to help block the needle tip. The clip may have a depending heel to help pivot the clip about a ledge to grip the needle shaft. A needle support may be provided to limit flexure of the needle which might otherwise allow the needle to come loose from the clip. Arrangements for limiting rotation of the needle hub and needle guard housing are provided, as is a protective shroud to reduce the risk of inadvertent activation of the needle guard. Further, the needle guard may be used with a catheter assembly. Also provided is an improved duckbill release mechanism.

    摘要翻译： 针护罩包括具有倾斜壁以夹持针轴的夹子和用于阻挡其尖端的远侧壁，其中倾斜和远侧壁可以通过成角度的支柱，诸如板簧的弹簧构件相互连接， 具有延伸穿过支柱的边缘的部分以偏置夹子以夹持针轴，并且远侧壁可以是或包括触针并且具有L形以限定唇缘以帮助阻止针尖。 夹子可以具有悬垂的鞋跟，以帮助夹子围绕凸缘枢转以夹紧针轴。 可以提供针支撑件来限制针的弯曲，否则可能会使针从夹子中松脱。 提供了用于限制针座和针保护壳的旋转的布置，保护罩也是如此，以减少针保护装置的无意的激活的风险。 此外，针护罩可以与导管组件一起使用。 还提供了改进的鸭嘴释放机构。

    摘要： An enclosed needle catheter insertion device (10) includes a catheter (12) and a needle insertion device (14) which are held together by cooperating arms (52, 53) with one or more detents (56) cooperating with a radially projecting surface (26) of the catheter hub (16). Insertion device (14) includes a guard housing (30) to enclose a needle (34) in a shielded position and a support housing (32) supporting the needle (34) for movement between a ready position, with the tip (36) of the needle (34) exposed, to the shielded position. Cooperating lock elements (47, 78) are provided for the housings (30, 32) which are positioned to define a lock actuation stage between the ready and shielded positions, whereat the needle is still within a passageway (54) defined by the cooperating arms (52, 53).
