    摘要: A safety cover, which securably and reliably prevents the readvancement of the tip of a cannula once it has been retracted thereinto, is designed having an elongate body which includes an axial channel having elements which displace and block linear passage of the cannula once it has been retracted. In a first embodiment the displacing elements are inwardly and rearwardly extending bristles which provide for unidirectional motion of the cannula relative to the safety cover, thereby locking the cannula once it has been retracted. In a second embodiment, the displacing element is the axial channel itself which has a curvate bias and distorts into a non-linear path once the cannula is retracted. In a third embodiment, the displacing element is a spring plate which, when compressed permits the cannula to pass through, but once the cannula has been retracted, expands to prevent the tip from being readvanced.

    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: A catheter insertion device is provided in which a needle cannula thereof has one or more markers to provide a visual and/or tactile indication to a user that the needle cannula has been withdrawn from a position in which the sharp tip thereof is exposed beyond the catheter tube to a position wherein a part of the cannula needle shaft and the tip are within a proximal portion of the catheter tube so as to impede fluid leakage through the tube, but removed from a distal portion of the tube to free it to flex.

    摘要: A catheter insertion device incorporating a simple lever and clip structure which will safely lock a catheter hub of a catheter assembly to a normally disposable cannula housing and guard structure and which, in a simple mode, enables separation of the catheter hub from the cannula assembly or structure upon retraction and protective guarding of the used cannula. Specifically, an aspect resides in providing the lever release clip for a safety catheter which upon unlocking and releasing of the catheter hub concurrently pushes the catheter hub off a nose guard of the cannula assembly, while enabling a physician or clinical personnel to release the catheter by employing only one hand. A further embodiment is adapted to enable separation between the catheter hub of a flexible catheter and the needle or cannula arrangement of a catheter insertion device by simply manipulating a lever arranged on a cannula structure or nose guard thereof by simply pushing against a push-tab element.
