Abstract: A safety intravenous catheter assembly includes a needle, a catheter hub having an axial bore extending through the catheter hub and a notch extending outwardly in the axial bore, a needle cover, and a notch clip connected to the needle cover. The notch clip is selectively maintained adjacent the needle throughout a range of positions from being in forceful contact with the needle to being generally spaced from the needle and selectively maintained adjacent the catheter hub throughout a range of positions from being in forceful contact with the catheter hub to being generally spaced from the catheter hub to lock the catheter hub to the needle cover while being operable to move the needle relative to the notch clip in a near frictionless relationship.

Abstract: A safety intravenous catheter assembly includes a catheter hub, a needle cover attachable to and releasably lockable with the catheter hub, and a needle which extends through and is withdrawn into the needle cover. In one embodiment, the safety intravenous catheter assembly is configured so that the fixedly connected catheter hub and needle cover may rotate around the needle. A stop assembly is attached to the needle and to the needle cover for maintaining a tip of the needle within the needle cover after catheter insertion. The stop assembly may include a first locking position whereby the catheter hub cannot disengage from the needle cover, and a second locking position whereby the catheter hub can disengage from the needle cover. The needle cover includes a notch clip which may be integrally formed as one-piece.

Abstract: A safety intravenous catheter assembly and method for use with a needle in one embodiment includes a catheter hub and a needle cover attachable to and releasably lockable with the catheter hub when the needle extends through the needle cover. A stop assembly is attached to the needle and to the needle cover for maintaining a tip of the needle within the needle cover. The stop assembly includes a first irrereversible locking position whereby the catheter hub cannot disengage from the needle cover, and a second locking position whereby the catheter hub can disengage from the needle cover.
