Catheter assembly and components thereof

摘要

Catheter assemblies are generally discussed herein with particular discussions extended to catheter assemblies having a tip protector, a valve, a valve opener, and optionally a needle wiper. The valve opener is disposed inside a catheter hub and is configured to be pushed by an IV set luer connector to open a valve following successful catheterization to pass fluids or other solutions through the catheter. A tip protector is incorporated to block the needle tip and prevent the same from accidental needle stick. A wiper is optionally included to wipe blood deposits from the needle when the same is retracted from the catheter.

1. A safety catheter assembly comprising:
a first hub comprising an interior cavity, an opening at a proximal end, and a catheter tube having a distal end opening extending distally of the first hub, the opening at the proximal end having a Luer taper; a needle having a needle shaft defining a needle axis projecting distally of an end of a second hub, said needle projecting through the catheter tube and comprising a needle tip; a valve for obstructing fluid flow positioned inside the interior cavity of the first hub; a valve actuating element slidingly disposed in the first hub for actuating the valve; and a third hub positioned between the first hub and the second hub having a needle protective device positioned therein in a ready position in which the needle tip is exposed and sized and shaped to prevent unintended needle sticks in a protective position; and wherein the protective device is made from a metallic component.
