  • Double-ended blower and volutes therefor
    Patent number: 10400773
    Abstract: A variable speed blower for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers in the gas flow path that cooperatively pressurize gas to desired pressure and flow characteristics. Thus, the blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.
    Type: Grant
    Filed: June 20, 2013
    Date of Patent: September 3, 2019
    Assignee: ResMed Pty Ltd
    Inventors: Geoffrey D. Daly, Alexander Virr, Stephen A. Lea, Dion Charles C. Martin, Nicholas J. Reed, Larry Puckeridge, Timothy Tsun-Fai Fu
