Abstract: A method for controlling a humidifier of a CPAP device including a controller, the method including controlling a heating element in the humidifier with command signals from the controller, sensing a temperature of a fluid in the humidifier with a sensor in the humidifier that transmits signals to the controller, establishing an acceptable operating range for the signal transmitted to the controller, determining whether the transmitted signal is within the acceptable operating range, if the signal is within the acceptable operating range treating the signal as being indicative of the temperature of the fluid in the humidifier and using the signal to control the heating element, and if the signal is outside of the acceptable operating range, the controller determines the humidifier to be unavailable.

Abstract: A breathable gas supply apparatus has a flow generator configured to pressurize a flow of breathable gas and a humidifier base unit configured to be coupled to the flow generator. A water container is configured to be removably coupled to the humidifier base unit and includes an air inlet and an air inlet passage extending into an interior of the water container from the air inlet. The air inlet passage is configured to direct the pressurized flow of breathable gas in a direction that is substantially parallel to a base of the water container. A barrier wall is provided across an outlet end of the air inlet passage and extends downward from the air inlet passage toward the water container base. In addition, a curved wall opposes both the outlet end of the air inlet passage and the barrier wall and extends downward toward the water container base. The breathable gas supply apparatus also includes a connector defining an airflow passage between an outlet of the flow generator and the air inlet of the water container.

Abstract: A CPAP device includes a flow generator with a blower configured to pressurize the flow of respiratory gas. A flexible face seal is positioned at an outlet end of a blower discharge path. The flexible face seal includes an aperture and a lip curling inwardly from a perimeter of the flexible face seal. A tub configured to hold a body of water and humidify the pressurized flow of respiratory gas includes a heat conducting base plate and a side wall. The side wall has a substantially flat portion that surrounds an air inlet opening. A base supports both the flow generator and the tub and includes a floor with a heater plate. A laterally positioned guide prevents the tub from being removed from the base in a vertical direction and includes a pair of C-shaped channel portions with open sides that face each other.

Abstract: A PAP device is configured to deliver a pressurized flow of respiratory gas to a patient's airways and includes a flow generator with a blower configured to pressurize the flow of respiratory gas. A flexible face seal is positioned at an outlet end of a blower discharge path. A tub configured to hold a body of water and humidify the pressurized flow of respiratory gas includes a heat conducting base plate and a side wall. A base supports both the flow generator and the tub and includes a floor with a heater plate and a spring biased catch configured to secure the tub to the base. The spring biased catch is configured so that applying a downward force on the tub so that the tub presses against the floor of the base secures the tub to the base and allows the tub to be released from the base.

Abstract: A humidifier includes a tub configured to hold a supply of water. The tub includes a tub lid and a tub base adapted to be coupled to the tub lid. The tub further includes a base plate formed of a heat conducting material and adapted to be coupled to the tub base and a seal positioned between the base plate and the tub base. The tub also includes a retaining mechanism with at least one projection that projects from the tub base and is configured to force the base plate against the seal so that the seal is secured against the tub base.

Abstract: A flow generator for a CPAP system configured to deliver a pressurized flow of respiratory gas to a patient's airways includes a housing and a motorized fan positioned within the housing. The motorized fan is configured to pressurize the flow of respiratory gas. In addition, an outlet port is provided in the housing. The outlet port is configured to connect to a humidifier or an air delivery tube and is in communication with an outlet of the motorized fan. The flow generator further includes a water collection receptacle in communication with the outlet port and the motorized fan outlet. The water collection receptacle is configured to collect water entering the flow generator through the outlet port before the water reaches the motorized fan outlet.
