ABSTRACT:
In general, the invention relates to an improved assembly for insertion of an intravenous catheter and method of insertion which minimizes or eliminates the potential for exposure to blood and other bodily fluids during the use and insertion of an intravenous catheter. An intravenous catheter hub has a side opening directly to connected to a port of a multi-port stopcock. A modified syringe and hollow-bore needle are attached directly to the base of the catheter and when properly inserted, the needle extends slightly beyond the tip of the catheter. After the needle is inserted beneath a patient's skin, the syringe is used to generate slight negative pressure so that blood immediately flows into the syringe as soon as a vein is punctured by the needle. The syringe is then removed and the flow of fluids into the patient may be regulated by the multi-port stopcock.
