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that engages with an engaging device, which is formed in the vicinity of the needle tip, when the hollow needle is withdrawn from the catheter sleeve.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when ready for use, extends through said check valve, and the check valve automatically closes once the needle is withdrawn.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 9):
A method for assembling a catheter insertion device comprising:\n forming a catheter hub comprising a body having an interior surface defining a bore with a female Luer, a shoulder on the interior surface and distal of a proximal opening to the bore, and a catheter tube attached at a distal end of the catheter hub; positioning a valve with at least one slit inside the bore of the catheter hub for blocking fluid flow through the bore, said valve being located inside the bore in a ready position and in a needle guarded position; positioning a valve actuator having a lengthwise axis slidingly in the bore of the catheter hub; said valve actuator comprising a nose section, a bore, a projection extending radially of the lengthwise axis, and a plunger section located proximally of the nose section and wherein said plunger section comprises a gap to permit fluid flow to flow through the gap and through the bore of the valve actuator; projecting a needle having a needle shaft defining a needle axis distally of an end of a needle hub and projecting the needle shaft through the catheter tube and the at least one slit so that a needle tip of the needle extends out a distal opening of the catheter tube; mounting a needle guard around said needle such that said needle guard and said needle are slidable relative to one another; wherein said needle guard comprises a surface for guarding the needle tip from unintended needle sticks when the needle tip is removed from the catheter hub; and wherein the nose section of the valve actuator is slidable into the valve to open the at least one slit when a male Luer tip is located in said bore of said catheter hub and pushing distally against an abutting surface at a proximal end of the valve actuator.
