More Information
Summary:The present invention discloses a compact respiratory therapy device suitable for use by a patient during sleep to provide respiratory pressure therapy, the device comprising: a housing; an inlet; an outlet; a motor including a rotor; an impeller configured to be rotated by the rotor to deliver a flow of air from the inlet toward the outlet, the impeller comprising: a first moulded part comprising a plurality of impeller blades, each impeller blade comprising a leading edge and a trailing edge; and a first shroud comprising a wall defining a periphery of a center opening of the impeller, the center opening providing an impeller inlet of a flow passage through the impeller; and a second moulded part comprising a hub structured for coupling to the rotor and a second shroud, wherein the compact respiratory therapy device is configured to deliver the flow of air from the outlet for delivery to the patient at a pressure between 4-30 cmH2O at an overall sound power level of less than 50 dB (A) thereby reducing any disturbance to a quality of sleep for the patient, and wherein: a diameter of the impeller is less than about 50 mm, and each shroud at least partly defines a flow passage through the impeller.
