Patent number: 10881820Abstract: 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.Type: GrantFiled: November 30, 2016Date of Patent: January 5, 2021Assignee: ResMed Pty LtdInventors: Geoffrey Crumblin, Michael Thomas Janiak, Dan Kao, Barton John Kenyon, Perry David Lithgow, Rohan Neil Primrose, Jim Saada, John Michael Snow, Duncan Lovel Trevor-Wilson, Alexander Virr, Arthur Kin-Wai Yee

Patent number: 9227035Abstract: A humidifier has a base unit with an engagement face that is configured to interface with a flow generator. The humidifier also has a tank configured to be removably received by the base unit and hold a volume of liquid. The tank has a side wall with an air inlet. The humidifier further has an air flow passage configured to receive an air connector of the flow generator at the engagement face of the base unit. The air flow passage is axially offset from a tank inlet. In addition, a cross-section of the airflow passage inlet and a cross-section of the tank air inlet are substantially perpendicular to a horizontal plane. In addition, a flexible face seal is positioned at an end of the air flow passage. An end of the face seal is configured to abut a side wall of the tank that includes the tank inlet when the tank is received in the base unit.Type: GrantFiled: July 29, 2014Date of Patent: January 5, 2016Assignee: ResMed LimitedInventors: Geoffrey Crumblin, Michael Thomas Janiak, Dan Kao, Barton John Kenyon, Perry David Lithgow, Rohan Neil Primrose, Jim Saada, John Michael Snow, Duncan Lovel Trevor-Wilson, Alexander Virr, Arthur Kin-Wai Yee
