Abstract
The invention provides a flushing system (1) configured to flush the pericardial cavity (PC) of a patient, wherein the system comprises: an infusion liquid outlet (4) to connect a first tube(20) having an infusion liquid lumen to guide a flow of infusion liquid from the system to the pericardial cavity, and an effusion liquid inlet (6) to connect to a second tube (21) having an effusion liquid lumen to guide the effusion liquid flow from the pericardial cavity to the system, a flow rate control system to control the flow rate of the infusion liquid flow at the infusion liquid outlet (4) on the basis of multiple sensor signals, wherein the flow rate control system comprises: a control unit (5) to provide a control signal on the basis of the sensor signals, and a pump device (3) to pump infusion liquid to the infusion liquid outlet (4) at an infusion liquid flow rate, wherein the infusion liquid flow rate is adjustable by the control signal of the control unit (5) and wherein the sensor signals registered by the control unit (5) comprise: an infusion liquid signal representative for the infusion liquid flow to the pericardial cavity, an effusion liquid signal representative for the e…
