ABSTRACT:
An over-the-needle type IV catheter system comprising a vented "closed hub" catheter assembly having a self-sealing injection port, a check valve operatively associated with the IV line, and a distally-situated flash chamber. Push flanges on the top and sides of the catheter assembly may be used to aid insertion, and may be rotated on the catheter housing as desired. A safety tube assembly having a trigger-actuated spring-biased needle retracting mechanism and a telescoping safety guard permit the operator to enclose the needle after catheterization using one hand. The coupling for the IV line is oriented in generally the same direction as the catheter tube, so that looping the IV line is unnecessary.
