Abstract
A fluid control valve is disclosed which, with a single valve, can manipulate flow between a saline supply, a contrast supply, a waste dump and a catheter. The control valve includes three primary positions including a contrast position where the valve provides communication between an injector and a contrast supply while isolating the saline supply and catheter. The valve also can be moved to a saline/waste position where the valve provides communication between the injector and the saline supply and/or the waste dump while isolating the contrast supply and catheter. The valve also can be moved to an injection position where the valve provides communication between the injector and the catheter. A single valve provides all three functions. The valve also may provide communication between a pressure transducer and catheter during the saline loading, waste dumping and contrast loading functions. The valve also provides protection or isolation of the pressure transducer during injection procedures.
