ABSTRACT:
An intraveneous catheter placement system is provided which includes an insertion tool/guard assembly and a flexible catheter having an attachment fitting at one of its ends. The insertion device includes a needle and a needle holder. The guard includes an elongate sleeve telescoped over the needle shaft, the sleeve having a blunt distal end and a fitting attached to its proximal end. When assembled, the needle holder, the fitting of the guard and the attachment fitting of the catheter interrelate with one another in mutually telescoping relation such that the needle cannot be removed from the lumen of the catheter prior to the locked deployment of the distal end of the guard sleeve distally of the pointed tip of the needle.
