1. A catheter assembly comprising:
- a first hub comprising a housing comprising an exterior surface and an interior surface defining an interior cavity;
a tube attached to the first hub and extending distally of the first hub;
a second hub comprising a housing comprising an exterior surface and an interior surface defining an interior cavity;
a needle having a needle tip attached to the second hub and projecting distally of the second hub and into the tube;
a valve comprising a top surface, a skirt depending therefrom, and an opening on the top surface having the needle projecting therethrough;
a valve opener comprising an actuating end, at least one leg extending proximally therefrom, anda wiper comprising a perimeter defining an opening and the needle in contact with the perimeter for wiping the needle as the needle is retracted away from the tube.

Abstract
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 on the needle when the same is retracted from the catheter.

15. A catheter assembly comprising:
-
a) a catheter hub comprising a housing comprising an exterior surface and an interior surface defining an interior cavity; b) a catheter tube attached to the catheter hub and extending distally of the catheter hub; c) a needle hub comprising a housing; d) a needle having a needle tip attached to the needle hub and projecting distally of the needle hub and into the catheter tube; e) a valve for limiting blood backflow positioned in the interior cavity of the catheter hub; f) a valve opener for opening the valve positioned proximally of the valve; and g) a tip protector positioned adjacent the valve opener for blocking the needle tip, wherein the tip protector comprises; (1) a tip protector housing having an interior surface; (2) a first arm extending from a distal wall of the tip protector housing biased towards the interior surface of the catheter hub; (3) a second arm extending from a proximal wall of the tip protector housing biased towards the interior surface of the catheter hub; and (4) a third arm extending from the proximal wall of the tip protector housing biased against a side of the needle. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
