1. A system for vacuum-assisted venous drainage, comprising:
at least one pressure regulating module that includes at least one active pressure regulating valve comprising at least one controllable proportional pressure valve having at least one supply line and at least one discharge line, and at least one pressure sensor that is integral to the controllable proportional pressure valve, 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 in the region of the pressure regulating valve as sensed by the pressure sensor integral to the controllable proportional pressure valve,
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,
an operating parameter recording module by means of which the operating parameters are monitored and/or recorded, and 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,
a hose set for fluid guidance between the discharge line of the system and a reservoir to be regulated, and
a presence detection unit (PDU), wherein a correct placement and a correct connection of the hose set is monitored and/or verified by means of the PDU, 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 PDU, and further wherein the PDU is configured to detect penetration of fluids into the at least one liquid reservoir and report said penetration to a control board.
