Abstract
A sterile intra-circulatory monitoring system utilizing an indwelling catheter with fluid under pressure being forced through a fluid line to the catheter. The system includes a normally stagnant pressure chamber to which a transducer is connected. The contents of the chamber are periodically flushed back into the fluid line by utilizing a flush valve and a venturi unit. The venturi unit may be an integral part of the flush valve or separate component. With the present invention a closed loop system is utilized which does not compromise the sterility of the system or the environment.
