ABSTRACT:
A disposable indwelling catheter placement unit includes a transparent plastic catheter for insertion into a blood vessel having depth indicating graduations thereon. The catheter is freely slidable into a transparent plastic tubular sheath having a slit line there along. The unit has a transparent inserter having an inner tube connected to a front portion of the inserter. The sheath tube is releasable from around the catheter responsive to movement through the inserter. By pushing the sheath tube forward into the inserter with the fingers while holding the inserter with other fingers, or pulling the split sheath from the inserter, the catheter can be pushed into the blood vessel up to a desired depth while maintaining sterility.
