Abstract
Various methods and systems are provided for flushing a medical gas flow system. In one embodiment, a method for a medical gas flow system comprises: performing a disinfecting cycle of a ventilation gas path comprising a plurality of gas flow passages by: flowing gas from a pressurized gas source of the medical gas flow system to a liquid disinfectant reservoir of a flush module; combining the gas with a liquid disinfectant stored within the liquid disinfectant reservoir to form a disinfectant aerosol; and flowing the disinfectant aerosol through the plurality of gas flow passages.

A method for a medical gas flow system, comprising:
- performing a disinfecting cycle of a ventilation gas path comprising a plurality of gas flow passages by:
- flowing gas from a pressurized gas source of the medical gas flow system to a liquid disinfectant reservoir of a flush module;
- combining the gas with a liquid disinfectant stored within the liquid disinfectant reservoir to form a disinfectant aerosol;
- and
- flowing the disinfectant aerosol through the plurality of gas flow passages.
A medical ventilatory system, comprising:
- a pressurized gas source;
- a plurality of gas flow passages forming a ventilation gas path;
- and
- a flush module, comprising:
- an inlet adapted to receive pressurized gas from the pressurized gas source via the plurality of gas flow passages;
- at least one liquid reservoir fluidly coupled to the inlet and adapted to store a liquid disinfectant or a liquid detergent;
- an outlet fluidly coupled to the at least one liquid reservoir and the ventilation gas path;
- and
- a mesh positioned between the at least one liquid reservoir and the outlet in a flow path of the pressurized gas, the mesh adapted to atomize the liquid disinfectant or the liquid detergent stored in the at least one liquid reservoir via the pressurized gas.
A method, comprising:
- during a first condition, flowing inhalation gas from a gas source to a patient breathing apparatus through a plurality of gas flow passages coupled together to form a ventilation gas path of a medical gas flow system while bypassing a flush module fluidly coupled to the plurality of gas flow passages, and flowing exhalation gas through a subset of the plurality of gas flow passages from the patient breathing apparatus;
- and
- during a second condition and without decoupling the plurality of gas flow passages after flowing the exhalation gas through the plurality of gas flow passages during the first condition, flowing at least one of a disinfectant or a detergent from the flush module through at least the subset of the plurality of gas flow passages.
