ABSTRACT:
The catheter system is used to safely insert a plastic catheter into a peripheral vein of patient who needs access for fluid and/or drug therapy. The catheter has added to the normal catheter hub a secondary port Y-Port that is used to attach IV line when catheter is inserted. This Y-port also has a one-way check valve to prevent blood from backing out the Y-port before the line is attached. The terminal end of the catheter hub has a rubber stopper to prevent blood from leaking out after the needle is removed. This feature effectively closes the previously open hub of the catheter, thus allowing near-bloodless IV access and allowing the flash chamber to be located within hub. The needle also includes a vent hole that vents blood into the flash chamber. A safety tube assembly as the back half of the catheter system includes protective tube and release mechanism which functions are to spring the needle out of catheter and house the used needle safely within the telescoping tube of the needle shuttle when trigger is pressed. The push flanges on the catheter hub are for easy catheter insertion and separation of the needle from the catheter.
