CATHETER SYSTEM FOR IMPROVED FIRST STICK SUCCESS

Abstract:

A pediatric catheter system may include a catheter adapter having a distal end, a proximal end, and a lumen extending therebetween. The system may include a catheter tube extending distally from the catheter adapter. The catheter tubing may be constructed of thermoplastic polyurethane for improved vein insertion success. The system may include a needle hub removably coupled to a proximal end of the catheter adapter and an introducer needle extending through the catheter tube. A proximal end of the introducer needle may be secured within the needle hub. The introducer needle may include a notch, which may also facilitate successful vein insertion. In response to insertion of the catheter tube into a vein of a patient, blood may flow into the introducer needle and out of the notch into a space disposed between an outer surface of the introducer needle and an inner surface of the catheter tube.
