Abstract
Embodiments include a vacuum assisted venous drainage (VAVD) system, including a regulator valve assembly configured to facilitate application of vacuum to a reservoir; a control unit configured to control the regulator valve assembly to facilitate controlling application of the vacuum; at least one pressure sensor coupled to the reservoir and configured to obtain pressure measurements of pressure in the reservoir; a heating element configured to heat the regulator valve assembly to a target temperature; and at least one temperature sensor configured to determine a temperature of the regulator valve assembly.

A vacuum assisted venous drainage, VAVD, system, comprising:
- a regulator valve assembly configured to facilitate application of vacuum to a reservoir;
- a control unit configured to control the regulator valve assembly to facilitate controlling application of the vacuum;
- at least one pressure sensor coupled to the reservoir and configured to obtain pressure measurements of pressure in the reservoir;
- a heating element configured to heat the regulator valve assembly to a target temperature;
- and
- at least one temperature sensor configured to determine a temperature of the regulator valve assembly.
A method, performed by a regulator for controlling vacuum in a reservoir to facilitate vacuum assisted venous drainage, VAVD, the method comprising:
- performing a thermal disinfection cycle;
- performing an operational task;
- and
- maintaining, during performance of at least a portion of the operational task, the temperature of the regulator valve assembly at a target temperature.
