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.
