Claim	A system for vacuum-assisted venous drainage, comprising at least one pressure regulating module, at least one active pressure regulating valve having at least one supply line and at least one discharge line, and at least one pressure sensor, by means of which pressure in a region of the pressure regulating valve is monitored and an actual pressure value is detected, and the pressure regulating valve designed and set up in such a way that negative pressure generated by the pressure regulating module is actively regulated by means of the pressure regulating valve on the basis of the actual pressure value. The system according to claim 1 , wherein the system further comprises a hose set for fluid guidance between the system and a reservoir to be regulated, as well as a presence detection unit, wherein a correct placement and a correct connection of the hose set is monitored and/or verified by means of the presence detection unit. The system according to claim 2 , wherein the hose set has at least one liquid reservoir and in that the correct placement and the correct connection of the liquid reservoir is monitored and/or verified by means of the presence detection unit. The system according to claim 1 , wherein the pressure regulating valve has at least one controllable proportional pressure valve in which the pressure sensor is integrated The system according to claim 1 , wherein the pressure regulating valve has at least one electrical and/or electronic pressure limiting element. The system according to claim 1 , wherein the system has an input and output device by means of which operating parameters are input by a user and are output by means of the operating parameters. The system according to claim 1 , wherein the system has an operating parameter recording module by means of which operating parameters of the system are monitored and/or recorded. The system according to claim 7 , wherein the operating parameter recording module has a patient data management interface by means of which data is exchanged with a patient data management system. The system according to claim 1 , wherein the system has a synchronization interface by means of which data is exchanged with one or more medical devices via the synchronization interface. The system according to claim 1 , wherein the system has sterile filters, inlets and outlets of the system and the supply line and the discharge line of the system being sterilely sealed by means of the sterile filters. The system according to claim 1 , wherein the system has a safe mode in which the supply line is closed and at the same time the discharge line is connected to the atmosphere. The system according to claim 11 , wherein the safe mode is automatically activated in the event of a system stop and/or a fault and/or loss of supply voltage. An assembly comprising at least one system for vacuum-assisted venous drainage, and at least one medical device; wherein the system comprises at least one pressure regulating module, at least one active pressure regulating valve having at least one supply line and at least one discharge line, and at least one pressure sensor, by means of which pressure in a region of the pressure regulating valve is monitored and an actual pressure value is detected, and the pressure regulating valve designed and set up in such a way that negative pressure generated by the pressure regulating module is actively regulated by means of the pressure regulating valve on the basis of the actual pressure value. A method for operating a system for vacuum-assisted venous drainage comprising at least one pressure regulating module, at least one active pressure regulating valve having at least one supply line and at least one discharge line, and at least one pressure sensor, wherein pressure in the system is monitored and measured pressure values are continuously generated, an actual pressure value is generated on the basis of the measured pressure values, and a negative pressure is generated by the pressure regulating module and is actively regulated and/or controlled by means of a pressure regulating valve on the basis of the actual pressure value. The system according to claim 4 , wherein the proportional pressure valve is a mechanical vacuum safety valve which is in fluid connection with the pressure regulating valve and opens at an adjustable actual pressure value. The system according to claim 6 , wherein the operating parameters are desired values and/or target values and/or warning limits and/or maximum limits; and wherein the operating parameters are displayed. The system according to claim 9 , wherein the exchanged data is at least one stop command for activating or deactivating the pressure regulating module. The assembly according to claim 13 , wherein the medical device is a heart-lung machine and/or a hypothermia device and/or a medical fixation device.
