Abstract
A device for humidifying respiratory gases. The device includes: a humidification component that holds a water volume; and a heating element that converts received electrical energy to electromagnetic radiation, wherein the electromagnetic radiation is transferred to the water volume, thereby heating the water volume to achieve a heated water volume.
Claims20
A device for humidifying respiratory gases, said device comprising:
- a humidification component comprising a wall forming a cavity for holding a water volume;
- and
- a heating element configured for converting received electrical energy to electromagnetic radiation, wherein said electromagnetic radiation is transferred to said water volume through at least a portion of said wall that is transmissive to said electromagnetic radiation, thereby heating said water volume to achieve a heated water volume;
- wherein said electromagnetic radiation transferred through the portion of said wall that is transmissive to said electromagnetic radiation is directed to said water volume by a portion of said wall comprising a non-transmissive surface.

A method for humidifying respiratory gases, said method comprising:
- receiving electrical energy at a heating element;
- converting, by said heating element, said electrical energy to electromagnetic radiation, wherein said electromagnetic radiation is transferred to a water volume of a humidification component comprising a wall forming a cavity for holding a water volume, said electromagnetic radiation being transferred through at least a portion of said wall that is transmissive to said electromagnetic radiation and directing said electromagnetic radiation to said water volume by a portion of said wall comprising a non-transmissive surface, thereby heating said water volume to achieve a heated water volume that produces water vapor;
- and
- flowing respiratory gases across said heated water volume, wherein said water vapor humidifies said respiratory gases.
1 more element
A method of manufacturing a device for humidifying respiratory gases, said method comprising:
- providing a humidification component comprising a wall forming a cavity for holding a water volume;
- disposing a heating element, configured for receiving electrical energy and converting said electrical energy to electromagnetic radiation, within a base unit;
- and
- coupling said humidification component with said base unit such that said electromagnetic radiation is transferred to said water volume through at least a portion of said wall that is transmissive to said electromagnetic radiation and said electromagnetic radiation is directed to said water volume by a portion of said wall comprising a non-transmissive surface, thereby heating said water volume to achieve a heated water volume, and wherein said heating element is independent of said humidification component.
