Patent number: 9038632Abstract: 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.Type: GrantFiled: July 29, 2014Date of Patent: May 26, 2015Assignee: 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

Publication number: 20150020805Abstract: A flow generator and humidifier construction is described, including a flow generator construction adapted to reduce noise output compared to known flow generators of comparable size. The flow generator includes a chassis forming first and second muffler volumes and a venturi-shaped connection portion, and a metal/polymer composite material blower enclosure which suppresses noise from the blower. The flow generator may be programmed to include a reminder system including a menu from which the user may request a reminder to take specific action, e.g., replace a component, call a physician, and/or enter patient data card, etc.Type: ApplicationFiled: September 30, 2014Publication date: January 22, 2015Inventors: Barton John KENYON, Arthur Kin-Wai YEE, Geoffrey CRUMBLIN, Perry David LITHGOW, Alexander VIRR, Donald Angus RICHMOND, Mark John PAYNE, Jim SAADA, John Michael SNOW, Duncan Lovel TREVOR-WILSON, Andrew Roderick BATH, Michael Thomas JANIAK, Dan KAO, Marek Tomasz SAPULA, Simone Marie JEHA, Andrew Charles MURRAY

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: ApplicationFiled: July 29, 2014Publication date: November 13, 2014Inventors: Geoffrey CRUMBLIN, Craig Edward HARRIS, 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

Publication number: 20130289429Abstract: An electrocardiograph comprising a base part and an operating and displaying part. The operating and displaying part is disposed on the base part and includes a displaying unit and an operating unit. The displaying unit is connected to the operating unit. The operating and displaying part is coupled with the base part via a rotating structure such that the operating and displaying part can rotate left and right relative to the base part. Since the operating and displaying part as described in the present application can rotate left and right relative to the base part, the user can adjust the view angle of the operating and displaying part as required.Type: ApplicationFiled: April 22, 2013Publication date: October 31, 2013Applicant: General Electric CompanyInventors: Ryan Jerome RAMOS, Huei Mian CHIAH, Duncan Lovel TREVOR-WILSON, Jun HOU
