A humidifier includes a base configured to retain a body of liquid therein, a top cover, and a seal disposed between the top cover and the base. At least a portion of the base is constructed of a heat conducting material. The top cover defines both an inlet and an outlet communicated with an interior of the base. The inlet is configured to receive pressurized breathable gas and the outlet is configured to deliver the pressurized breathable gas with added humidity.

Humidifier with structure to prevent backflow of liquid through the humidifier inlet

A humidifier is provided including a first humidifier part, a second humidifier part connectable with the first humidifier part, and a sealing gasket disposed between the first and second humidifier parts. The second humidifier part is configured to hold a volume of liquid therein and the first and second humidifier parts and the sealing gasket define first and second internal passages within the humidifier. The first passage is disposed so as to be exposed to a surface of the volume of liquid and the second passage is isolated from at least one of the first passage and the surface of the volume of liquid. The second passage is configured to communicate with a pressure and/or sound sensing device.

Air pressure signal monitoring in apparatus for treating sleep disordered breathing

An apparatus for humidifying breathable gas includes (a) at least one humidifier part configured to retain a body of liquid therein and defining at least one chamber therein, (b) an inlet communicated with an interior of the at least one humidifier part and connectable to a blower outlet, and (c) an oulet communicated with the interior of the at least one humidifier part and connectable to a patient supply conduit. The at least one chamber is arranged such that liquid from the body of liquid is prevented from exiting the at least one humidifier part through the inlet thereof when the at least one humidifier part is rotated from a working, upright orientation.
