Abstract
A flexible, winged, over-the-needle catheter assembly and a needle assembly are releasably locked together at their distal ends to prevent relative axial movement therebetween during insertion into a vein. After insertion, the needle assembly can be easily unlocked and then retracted from the catheter assembly. Relative rotation between the catheter and the needle assemblies is prevented by interfitting surfaces thereon, and the direction that the needle bevel faces is indicated by indicia on the catheter wings.
