The present invention relates to a device (10) for supplying a mist of liquid (F). The device (10) is used in combination with a container (20) with an opening (200) for containing the liquid (F). The device (10) includes a main body (100) comprising: (i) a center axis (C); (ii) a liquid chamber (110) formed inside the main body (100), into which a predetermined amount of liquid (F) can be taken up; (iii) a first port (112) formed in a base wall (114) of the main body (100) forming a bottom surface (116) of the liquid chamber (110) so as to face the opening (200) when the device (10) and the container (20) are combined with each other, through which the liquid (F) can flow; (iv) a second port (118) formed in the base wall (114) at a position different from the position where the first port (112) is formed so as to face the opening (200) when the device (10) and the container (20) are combined with each other, through which the liquid (F) can flow; and (v) an aperture (120) connected to the liquid chamber (110), through which a mist of liquid (F) can be released to the outside of the main body (100). The device (10) further includes: a connecting section (122) provided on the main body (100) so as to extend from it in a direction away from the base wall (114) and used for connecting the container (20) to the main body (100); an atomizing element (124) interposed between the liquid chamber (110) and the aperture (120) to atomize the liquid (F) taken up in the liquid chamber (110) and release a mist of the liquid (F) to the outside of the main body (100) from the aperture (120); a first valve (126) mounted on the main body (100) corresponding to the first port (112), wherein the first valve (126) permits the liquid (F) in the container (20) flowing into the liquid chamber (110) through the first port (112) under the influence of gravity, and prevents the liquid (F) in the liquid chamber (110) flowing into the container (20) under the influence of gravity; and a second valve (128) mounted on the main body (100) corresponding to the second port (118), wherein the second valve (128) prevents the liquid (F) in the container (20) from flowing into the liquid chamber (110) through the second port (118) under the influence of gravity, and selectively permits or prevents the liquid (F) in the liquid cha

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.

A system for humidifying oxygen for low-flow oxygen therapy includes a volume-adaptable water reservoir that contains, in addition to water, a water-vapor-permeable membrane.

A gases humidifier comprising: a gases inlet and an outlet, a removable humidification chamber cartridge with a heater source adapted to vaporize fluid; and a metering arrangement adapted to connect to and transfer fluid from a fluid supply to the humidification chamber.

A positive airway device is configured to deliver a pressurized flow of humidified respiratory gas to a patient's airways and includes a flow generator with a blower portion and a docking portion laterally adjacent to the blower portion. The docking portion is separated from the blower portion by a divider and comprises a cavity configured to laterally receive a humidifier tub. The humidifier tub comprises a first tub subsection with an air inlet opening and an air outlet opening and a second tub subsection. A flange extending outwardly from an outer surface of the humidifier tub forms a transition between the first and second tub subsections. The humidifier tub is configured so that when the humidifier tub is fully received by the docking portion, the first tub subsection is enclosed within the cavity and the second tub subsection remains outside the cavity.
