Patent

CA 2178267

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.
