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.
Claims18
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 fora 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, using the heating element, a thermal disinfection cycle to disinfect the regulator valve assembly,
- perform, using the regulator valve assembly, an operational task, and
- maintain, using the heating element and during the performance of at least a portion of the operational task, the temperature of the regulator valve assembly at the target temperature.
A method performed by a regulator valve assembly 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;
- maintaining, during performance of at least a portion of the operation task, a temperature of the regulator valve assembly at a target temperature for a target duration sufficient to kill bacteria and mold.
