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that engages with an engaging device, which is formed in the vicinity of the needle tip, when the hollow needle is withdrawn from the catheter sleeve.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when ready for use, extends through said check valve, and the check valve automatically closes once the needle is withdrawn.

Abstract: Infusion systems and related methods involving a catheter hub and an extension or IV administration set having a male Luer connector for fluid communication with the catheter hub. A support adaptor is provided with the extension or IV administration set and has a body with a length between first and second ends, and a body wall having a continuous wall surface in a radial direction relative to the length and which defines an exterior of the body. An internal wall of the support adaptor defines a bore with the body wall, wherein the bore has first and second openings. A tubing length is located in the bore and extends out of the second opening. The bore includes first and second bore sections. Optionally, the second bore section is angled relative to the first bore section. A support surface is located beneath the bore, elevation wise.

Abstract: Embodiments of the shield assemblies include a shield that is pivotably secured to a needle hub. A ball-and-socket hinge secures the shield and the hub to one another. The assembly includes a reversible shield lock to hold the shield in the needle-protected position. The assembly further includes at least one stop piece to stop the shield from over-rotating.

Abstract: A catheter assembly including a catheter hub being connectable to a device for the infusion or withdrawal of fluids; a hollow extension tube connected at its distal end to the catheter hub, the extension tube connectable at its proximal end to a device for infusing fluid into the chamber within the catheter hub; a valve assembly disposed within the chamber of the catheter hub having a first valve member and a second valve member preventing the flow of fluid through the chamber to or from the proximal end of the catheter hub. A needle guard assembly is also provided.
