Abstract

Abstract An improved IV system comprising one or more medication bags in which fluid is packaged, a safety IV catheter assembly for delivering fluid from the medication bags to the patient, and a quick-disconnect fluid coupler by which fluid tubing from respective medication bags may be quickly and efficiently connected to fluid tubing associated with the catheter assembly. Each medication bag includes an integral flow control device and drip chamber by which to accurately and selectively regulate the rate at which fluid is supplied to the catheter assembly. The catheter assembly includes a detachable and disposable safety housing into which a solid core trocar can be withdrawn and shielded after making a veni puncture through the patient's tissue. The fluid coupler includes a pair of locking fingers that are rotated through respective locking perforations located adjacent the fluid tube to which the coupler is to be connected. A hollow fluid cannula extends from the coupler into the fluid tube so as to establish a flow path therebetween.
