ABSTRACT:
A dispensing system and apparatus for introducing contrast media intravascularly during catheterization procedures, which apparatus 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 segment of tubing to the stopcock. A top check valve is provided in the second segment of tubing, which extends from the stopcock. A bottom check valve is provided in the second segment of tubing spaced from the first check valve and a bottom stopcock is also provided in the second segment of tubing below the bottom check valve. A third length of IV tubing projects from the bottom stopcock and receives a second luer lock fitting for securing the bottom end of the third length of IV tubing to a conventional manifold. When the dispensing system is operational, contrast fluid is allowed to flow through the first and second segments of tubing by manipulating the top stopcock, it then flows into the manifold by manipulating the bottom stopcock and is injected intravascularly into the body from the manifold during the catheterization procedure.
