Claim 0:
1. A safety catheter assembly, comprising:
a catheter hub assembly including a catheter hub having an open proximal end and a distal end having a catheter extending distally therefrom, the catheter hub having an interior cavity defined between the open proximal end and the distal end;
a needle having a sharp distal tip extending distally from a needle hub, the needle adapted to slidably extend through the catheter hub into the catheter such that the distal tip extends beyond the distal end of the catheter when the safety catheter assembly is in a ready position;
a collar having an open distal end and a proximal end positioned between the catheter hub assembly and the needle hub, an upright extending upwardly from the top of a distal portion of the collar, the distal end of the collar opens into a chamber adapted to receive the proximal end of the catheter hub;
a needle tip protector at least partially housed in the collar, the needle movable through the needle tip protector between the ready position and a safe position wherein the distal tip of the needle is non-removably captured in the needle tip protector;
wherein in the ready position, the proximal end of the catheter hub is in the chamber of the collar and the collar and the catheter hub are in fixed engagement with each other; and
wherein in the safe position, the collar and the catheter hub are separable from each other.
