The present invention relates to a flushing system (1) configured to flush the core film strength (PC) of the patient, the injection liquid lumen in order to induce the flow of the infusion liquid into the core film strength from the flushing system spilled liquid inlet for connection to the first the second tube (21) having an outflow liquid lumen in order to induce the leakage liquid flows into the flushing system from the injection liquid outlet (4), the center film strength for connecting a tube 20 having 6, and the number of the injection liquid outlet 4 on the basis of the sensor signal comprises a flow rate control system for controlling the flow rate of the infusion liquid flow, said flow rate control system is a control signal based on the sensor signal control unit 5, and the pump apparatus for pumping infusion liquid from the infusion liquid flow rate to the injection liquid outlet (4) (3) for providing an-infusion liquid flow rate by the control signal of the control unit 5 adjustment possible-contained, and registered by the control unit 5, the sensor signal is leaked liquid signals indicating the leak liquid flow rate from the injection fluid signal, the center film strength represents the infusion liquid flow to the core film strength, leakage from the core film strength produced by the hematocrit sensor 12 indicating the hyeolson flow rate in the liquid fluid volume signal, and seam the film strength, the second tube 21 or the first tube (20) generated by a pressure sensor disposed on or in conjunction in my the core includes a pressure control signal indicating the pressure in flawless. The present invention also provides a method for monitoring the hyeolson volume or flow rate from the core film strength on the basis of the plurality of sensor signals, but also reduces the accumulation of blood and clots in the seam the film strength and reduce the hyeolson after surgery, cardiac depression in order to reduce the risk of increase it provides a meth
