Abstract
A humidifier is configured to humidify a flow of pressurized respiratory gas. The humidifier includes a tub base configured to retain a body of water and a tub lid configured to cover the tub base. The humidifier also includes an inlet passage configured to receive the flow of pressurized respiratory gas and deliver the pressurized respiratory gas to an interior of the humidifier. At least a portion of the inlet passage is configured to float on the body of water retained in the tub base.
Claims20
A humidifier configured to humidify a flow of pressurized respiratory gas, the humidifier comprising:
- a tub base configured to retain a body of water;
- a tub lid configured to cover the tub base;
- and
- an inlet passage configured to receive the flow of pressurized respiratory gas and deliver the pressurized respiratory gas to an interior of the humidifier, at least a portion of the inlet passage being configured to float on the body of water retained in the tub base.
A humidifier configured to humidify a flow of pressurized respiratory gas, the humidifier comprising:
- a tub base configured to retain a body of water;
- a tub lid configured to cover the tub base;
- and
- a flexible inlet passage located inside the humidifier and configured to receive the flow of pressurized respiratory gas,
- wherein the flexible inlet passage is configured to be supported by the body of water in the tub base.
A humidifier configured to humidify a flow of pressurized respiratory gas, the humidifier comprising:
- a tub base configured to retain a body of water;
- a tub lid configured to cover the tub base;
- an inlet passage configured to receive the flow of pressurized respiratory gas, the inlet passage extending inwardly from an exterior of the humidifier;
- and
- an outlet passage configured to discharge the humidified flow of pressurized respiratory gas, the outlet passage extending inwardly from the exterior of the humidifier,
- wherein the inlet passage is configured to be flexed or pivoted by the surface of the water so that the inlet passage remains afloat on the water regardless of the orientation of the humidifier, and
- wherein the outlet passage is configured to be flexed or pivoted by the surface of the water so that the outlet passage remains afloat on the water regardless of the orientation of the humidifier.
