ABSTRACT:
A tubing set, the major portions of which are defined from a trilumen section of tubing, comprises three lines including an inflow line, an outflow line and a pressure sensing line. The inflow line includes a header portion engageable about the rollers of a peristaltic pump, a delivery tube mounting a male luer fitting for engagement with a patient cannula, and a pair of clampable supply tubes with bag spikes for communication with saline bags. The pressure sensing line includes a pressure transmitting elongate tubular diaphragm mounted within a fluid chamber directly adjacent the patient end of the line. The pressure transmitting diaphragm communicates with an elongate dry or air tube which, at the remote end, communicates with an appropriate pump-mounted pressure transducer or the like. The outflow line includes a pressure control and relief assembly comprising a pair of parallel tubes respectively for association with a solenoid valve for the selective control of liquid flowing therethrough and for association with a mechanical relief valve for allowing flow therethrough and releasing pressure upon the occurrence of excess pressure. The outflow line also includes a terminal discharge tube incorporating a fluid trapping loop therein to preclude suction-defeating drainage of fluid upon deactivation of the system.
