Publication number: 20210379305Abstract: A flow generator is configured to pressurize a flow of breathable gas to within a range of about 2-30 cm H2O for delivery to a patient's airways. The flow generator includes a blower with at least one impeller and a motor configured to drive the at least one impeller. The flow generator also includes a substantially planar blower mount configured to support the blower. The blower mount includes a flexible blower receptacle portion configured to receive and support the blower. The blower receptacle portion includes an outlet opening that is axially aligned with an air outlet of the blower. The flow generator also includes housing that encloses the blower and the blower mount. The housing has an inner surface that engages a perimeter of the blower mount.Type: ApplicationFiled: August 23, 2021Publication date: December 9, 2021Inventors: Richard Llewelyn JONES, Saad NASR, Joern LANGE, Ernie Wei-Chih TSAI, Barton John KENYON, Geoffrey CRUMBLIN
