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 The catheter assembly includes a detachable and disposable safety housing into which a solid core trocar can be withdrawn and shielded after making a veni puncture through the patient's tissue.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.
For use in an IV system including a medication bag having a fluid compartment in which a supply of fluid to be delivered to a patient is packaged and a platen surrounding and supporting said fluid compartment, fluid delivery means by which to deliver fluid from the fluid compartment of the medication bag to the patient, and flexible fluid tubing means fluidically connected between the fluid compartment of the medication bag and the fluid delivery means, the improvement of flow control means located within said platen and positioned between said fluid compartment and said delivery means by which to regulate the rate at which fluid is supplied therebetween, said flow control means comprising means by which to apply a compressive force to the fluid tubing means to change the cross-sectional flow area thereof, such that the rate at which fluid is supplied to said fluid delivery means is dependent upon the compressive force applied to said tubing means.
A medication bag to be interconnected with an IV catheter and having a fluid compartment in which fluid is packaged for delivery to a patient by way of a catheter, said medication bag comprising a platen to surround and support said fluid compartment, a fluid tube molded into said platen and communicating fluidically with said fluid compartment and the catheter so that the fluid packaged in said compartment can be supplied to the catheter, and drip chamber means molded into said platen and communicating with said fluid tube so as to regulate the rate at which fluid is supplied from said fluid compartment to said catheter via said fluid tube.
A flow control device for use in an IV system including a medication bag having a fluid compartment in which fluid is stored for delivering to a patient and a platen surrounding and supporting said fluid compartment, fluid delivery means by which to delivery fluid from said compartment to the patient, and flexible tubing means fluidically connected between said fluid compartment and said fluid delivery means to supply fluid therebetween, said flow control device comprising:
