A safety catheter device includes a catheter hub, a housing removably coupled to the catheter hub; a needle, and a member, the housing including a radially outwardly directed projection operable to engage the interior aspect of the catheter hub and radially moveable inwardly sufficiently to disengage therefrom, the projection being held against moving radially inwardly sufficiently to disengage when the needle is in a first position with the needle distal tip exposed and being free to move radially inwardly sufficiently to disengage coincident with the needle being moved into a second position with the needle distal tip disposed in the housing.

Safety catheter device with removably attached housing

A generally rigid molded plastic catheter hub attachment () includes one or more co-molded elastomeric gaskets ().

Sealing catheter hub attachment

An enclosed needle catheter insertion device () includes a catheter () and a needle insertion device () which are held together by cooperating arms () with one or more detents () cooperating with a radially projecting surface () of the catheter hub (). Insertion device () includes a guard housing () to enclose a needle () in a shielded position and a support housing () supporting the needle () for movement between a ready position, with the tip () of the needle () exposed, to the shielded position. Cooperating lock elements () are provided for the housings () which are positioned to define a lock actuation stage between the ready and shielded positions, whereat the needle is still within a passageway () defined by the cooperating arms ().

Enclosed needle device with duckbill release mechanism

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.
