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that engages with an engaging device, which is formed in the vicinity of the needle tip, when the hollow needle is withdrawn from the catheter sleeve.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when ready for use, extends through said check valve, and the check valve automatically closes once the needle is withdrawn.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 18):
A catheter insertion device comprising:\n a catheter hub comprising a body with an interior defining a bore having a female Luer at a proximal end and an internal shoulder; a catheter tube with a distal end opening, said catheter tube attached to and extending distally of the catheter hub; a needle having a needle shaft with a needle tip, said needle shaft projecting distally of an end of a needle hub and through the catheter tube with the needle tip located distally of the distal end opening of the catheter tube; a valve with at least one slit sized and shaped to obstruct fluid flow, said valve being positioned inside the bore of the catheter hub and remaining inside the bore of the catheter hub when the needle is removed from the catheter hub; a valve actuator having a lengthwise axis slidingly disposed in the bore of the catheter hub to actuate the valve, the valve actuator comprising a nose section structured to push the valve to open the at least one slit, wherein said valve actuator comprises a bore and a plunger section located proximally of the nose section, said plunger section comprising spaced apart plunger components having a gap to permit fluid flow to flow through the plunger components and the bore of the valve actuator; a needle guard located proximally of the nose section, said needle guard comprising a surface located to a side of the needle shaft in the ready position and the needle guard and the needle movable relative to one another so that the surface is distal of the needle tip in the protected position to guard the needle tip from unintended needle sticks; and wherein the plunger section comprises an actuating surface that is exposed for abutting by a male Luer tip after the needle guard is removed with the needle from the catheter hub.
