A tub for a humidifier includes an inner tub configured to hold a supply of water; an outer tub configured to receive the inner tub, the outer tub including a bottom and a cavity being formed between the bottom and the inner tub when the inner tub is received in the inner tub; and a valve configured to control a flow of the supply of water from the inner tub to the cavity. The valve is closed to prevent the flow when the inner tub is received in a first position in the outer tub and open to permit the flow when the inner tub is received in a second position in the outer tub.

A respiratory device comprises artificial respiration means for generating and maintaining an oxygen-containing respiratory gas flow. Coupled thereto is a tube with humidification means having an atomizer for humidifying the respiratory gas flow and a humidification fluid source that provides a humidification fluid. A spray nozzle thereof comprises a microscopic spray opening in an atomizer body which provides a passage between inlet and outlet sides of the atomizer body and is able and configured to receive a humidification fluid under increased pressure on the inlet side and deliver a fine mist on the outlet side. The atomizer debouches directly into the respiratory channel of the tube. Pressure means are provided which impose an increased operating pressure on the humidification fluid upstream of the atomizer that is connectable via a fluid conduit to the humidification fluid source and pressure means to receive the humidification fluid under the increased operating pressure.

A humidifier comprises a water reservoir and a reservoir dock configured to receive the water reservoir in an operative position. The water reservoir is configured to hold a volume of liquid. The water reservoir includes a chamber and a single conduit providing an inner opening arranged within the chamber. The reservoir dock includes a dock inlet conduit arranged to receive the flow of air from the RPT device. The dock inlet conduit is structured and arranged to extend within the single conduit of the water reservoir when the water reservoir reaches the operative position such that the dock inlet conduit and the single conduit at least partially overlap one another. The dock inlet conduit includes an inner opening arranged adjacent the inner opening of the single conduit when the water reservoir reaches the operative position, the inner openings of the dock inlet conduit and the single conduit arranged to provide an inlet for the flow of air into the chamber and an outlet for delivering a humidified flow of air from the chamber.

A device for humidifying respiratory gases. The device includes: a humidification component that holds a wafer 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.

The present invention relates to a humidifying device for a breathing mask. The breathing mask includes a breathing tube assembled thereto. The humidifying device includes a body, a liquid discharger, a liquid receiver, and a water-absorbent member. The body is connected to the breathing tube. The body includes a passage communicating with the breathing tube. The liquid discharger is fixed to the body. The liquid discharger includes a liquid outlet communicating with the passage. The liquid receiver is fixed to the body and is disposed below the liquid discharger. The liquid receiver includes a liquid inlet communicating with the passage. The water-absorbent member consists of a filtering material. The water-absorbent member is accommodated in the passage and disposed between the liquid outlet and the liquid inlet.

A valve unit (10) for a fluid supply chamber (20) of a respiratory support system (100) that provides humidified respiratory gases is provided. The valve unit comprises a first port (11) and a second port (12) and a fluid passageway (14) formed therebetween. The valve unit further comprises a valve (13) arranged in the fluid passageway (14) for controlling the flow of fluid between the first port (11) and second port (12). The valve unit is arranged to seal against an interior surface (21) of the fluid supply chamber (20) proximate the first port (11) and against an exterior surface (22) of the fluid supply chamber (20) proximate the second port (12) when the 10 valve unit (10) is connected to the fluid supply chamber (20).

An electronic atomization apparatus with a switch-closed atomizer and an electronic simulation cigarette are disclosed. The electronic atomization apparatus comprises a battery rod (10), an atomizer (20) arranged on a top end of the battery rod (10), an atomization liquid storage device (30), a sleeve (40) and a suction nozzle upper cover (50). When in use, the atomization liquid storage device is placed in the sleeve, and the suction nozzle upper cover is sleeved on the sleeve. The atomization liquid storage device is pushed to move down by rotating the suction nozzle upper cover, while the atomizer-abuts against a sealing rubber (35), so that the atomization liquid storage device and the sealing rubber (35) slide relative to each other in opposite directions, so as to open a liquid outlet (32) of the atomization liquid storage device to communicate with a liquid inlet (22) of the atomizer.

A heater wire including at least one extending component disposed thereon. The heater wire is positioned within a respiratory gas conduit. The heater wire may include a wire component and a groove that extends along a length of the heater wire. The heater wire may also include threads extending from an outer surface of the heater wire that faces away from the wire component. The threads may be woven or braided threads.

A backspill prevention apparatus prevents water from a humidifier portion of a positive airway pressure (PAP) device from reaching a blower motor of a PAP device. The backspill prevention apparatus can include a variety of different devices, and is placed somewhere along an air passageway between a blower motor and a humidifier portion of a PAP device.
