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 for a target duration sufficient to kill bacteria and mold;
- 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;
- a heating element configured to heat the regulator valve assembly to a target temperature for a target duration sufficient to kill bacteria and mold;
- and
- at least one temperature sensor configured to determine a temperature of the regulator valve assembly;
- wherein the control unit is configured to perform a thermal disinfection cycle to disinfect the regulator valve assembly by using the heating element to heat the regulator valve assembly to the target temperature for the target duration sufficient to kill bacteria and mold wherein the control unit is configured to, using the regulator valve assembly, apply a vacuum to the reservoir;
- and maintain, using the heating element and while the vacuum is applied to the reservoir, the temperature of the regulator valve assembly at the target temperature.
