Abstract
A humidification canister for humidifying a breathing gas, the humidification canister includes a fluid supply configured to supply a fluid and a first gas flow path in fluid communication with the fluid supply. A first gas flow path is configured to humidify the breathing gas with the fluid. A second gas flow path at least partially surrounds the first gas flow path. A method of insulating a breathing gas in a humidification canister using a gas is also disclosed.
Claims24
A humidification canister for humidifying a breathing gas, the humidification canister comprising:
- a fluid supply configured to supply a fluid;
- a first gas flow path in fluid communication with the fluid supply, the first gas flow path configured to humidify the breathing gas with the fluid;
- and
- a second gas flow path at least partially surrounding the first gas flow path.
A method of pressurizing a supply of humidification fluid within a humidification canister comprising the steps of:
- a) generating a flow of a breathing gas along a first gas flow path;
- b) generating a flow of an insulating gas along a second gas flow path;
- c) providing a supply of a humidification fluid within the humidification canister to humidify the breathing gas;
- and
- d) providing fluid communication between the second gas flow path and the supply of the humidification fluid to pressurize the supply of the humidification fluid with the insulating gas.
A method of insulating a breathing gas in a humidification canister using a gas, the method comprising the steps of:
- a) directing a flow of a breathing gas along a first gas flow path including the humidification chamber;
- and
- b) directing a flow of an insulating gas along a second gas flow path including an insulating chamber at least partially surrounding the humidification chamber, wherein the insulating gas at least partially insulates the breathing gas.
A humidification canister for humidifying a flow of breathing gas, the humidification canister comprising:
- means for supplying a fluid;
- means for humidifying a first gas flow with the fluid along a first gas flow path;
- and
- means for at least partially insulating the first gas flow with a second gas flow.
