1. A catheter insertion device comprising:

  • a catheter hub comprising a body having an interior surface defining a bore with a Luer taper, a shoulder inside the bore and distal of a proximal opening to the bore, and a catheter tube attached at a distal end of the catheter hub;

    a valve comprising at least one slit located inside the bore of the catheter hub for limiting fluid flow through the bore and remaining inside the bore in a ready position and a needle guarded position;

    a valve actuator slidably disposed in the bore of the catheter hub;

    said valve actuator comprising a nose section, a bore, a projection extending radially of a lengthwise axis of the valve actuator, and a plunger section comprising plunger components located proximally of the nose section, said plunger section comprising a gap between the plunger components to permit fluid flow through the gap and the bore of the valve actuator, wherein said plunger section comprises an abutting surface at a proximal end for pushing by a male Luer tip when said male Luer tip is located in said bore of said catheter hub;

    a needle having a needle shaft defining a needle axis projecting distally of an end of a needle hub and through the catheter tube with a needle tip of the needle shaft extending out a distal end opening of the catheter tube; and

    a needle guard comprising a surface for guarding the needle tip from unintended needle sticks when the needle tip is removed from the catheter hub, said surface of the needle guard being located to a side of the needle shaft in the ready position and being located distal of the needle tip in the needle guarded position to guard the needle tip.
