Abstract
A dispensing system and apparatus for introducing contrast media intravascularly during catheterization procedures, which includes connected segments of tubing that serve as a flow path into the vascular system. A spike is provided at one end of a first segment of the tubing for 'spiking' a bottle of contrast media. A stopcock is also provided in the first segment of tubing and a luer lock fitting is attached to the stopcock for connecting a second length of IV (intravascular) tubing fitted with a companion luer lock fitting. In a first preferred embodiment a top check valve is provided in the second segment of tubing, which terminates in the top of a reservoir. A second stopcock is connected to the bottom of the reservoir and a third length of IV tubing projects from the second stopcock and receives a bottom check valve and a second luer lock fitting for securing the bottom end of the third length of IV tubing to a conventional manifold. In alternative embodiments of the invention the top and bottom check valves are omitted from the dispensing system. When the dispensing system is operational, contrast fluid is allowed to flow into the reservoir by manipulating the top stopcock, from which reservoir it flows into the manifold by manipulating the second stopcock and is injected intravascularly into the body from the manifold during the catheterization procedure.
