Abstract:
Embodiments of a catheter insertion device are discussed comprising: an approximately hollow cylindrical catheter sleeve, at whose distal end a catheter is attached; a needle sleeve with a hollow needle, which is attached thereto and which, when ready for use, extends through the catheter sleeve and the catheter, and; a needle protective element that is arranged inside the catheter sleeve while being able to move on the needle. Said needle protective element has an engaging section that engages with an engaging device, which is formed in the vicinity of the needle tip, when the hollow needle is withdrawn from the catheter sleeve. A check valve is placed inside the catheter sleeve between the catheter and the needle protective element. The hollow needle, when ready for use, extends through said check valve, and the check valve automatically closes once the needle is withdrawn.

Claim (Index 1):
A catheter insertion device comprising:\n 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 actuating element, 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 being located to a side of the needle shaft in the ready position and movable distal of the needle tip in the needle guarded position to guard the needle tip.
