    Abstract: A compact respiratory therapy device suitable for use by a patient during sleep to provide respiratory pressure therapy such as at a pressure between 4-30 cmH2O includes a housing, an inlet, an outlet, a motor including a rotor, and an impeller configured to be rotated by the rotor to deliver a flow of air from the inlet toward the outlet. The impeller includes a set of impeller blades, each impeller blade comprising a leading edge and a trailing edge; and a first shroud and a second shroud, each shroud at least partly defining a flow passage through the impeller, the first shroud comprising a wall defining a periphery of an impeller inlet. 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. A diameter of the impeller is less than 50 mm. The first shroud and the second shroud are configured such that the flow passage is narrower in an axial direction at an outer portion of the impeller than at an inner portion of the impeller; and a diameter of the impeller inlet is at least 50% of the diameter of the impeller.

    Abstract: Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder includes a first chamber, a second chamber, at least one inlet tube structured and configured to allow ambient air to enter the first chamber, at least one flow tube structured and configured to allow air to pass from the first chamber to the second chamber, and a blower structured and configured to produce a flow of air at positive pressure. The blower is positioned in the first chamber and structured and configured to receive air from the second chamber. The blower includes a housing structured and configured to sealingly separate air flow through an interior of the housing from the first chamber. The at least one inlet tube is axially spaced from the at least one flow tube.

    Abstract: Apparatus for providing air at positive pressure for respiratory therapy to a patient includes a pneumatic block including at least first and second blower sub-assemblies and a common chassis assembly configured to support each of the at least first and second blower sub-assemblies. The at least first and second blower sub-assemblies are different structurally from one another in at least one aspect. Each of the at least first and second blower sub-assemblies includes a corresponding blower configured to produce a flow of air at a therapeutic pressure. The common chassis assembly and the first blower sub-assembly form a first configuration of the pneumatic block, and the common chassis assembly and the second blower sub-assembly form a second configuration of the pneumatic block. The air flow path and the chamber arrangement of the first configuration is different than the air flow path and the chamber arrangement of the second configuration.

    Abstract: An interfacing structure for a mask system includes a cushion component adapted to contact the patient's face in use and a cushion-to-frame component provided to the cushion component. The cushion-to-frame component is structured to secure the cushion component to a mask frame of the mask system. The cushion-to-frame component includes a cushion side adapted to interface with the cushion component and a frame side adapted to interface with the mask frame. The cushion side includes a platform to engage and support the cushion component. The platform provides an engagement surface to engage the cushion component and inner and outer flanges provided to opposing ends of the platform to guide, support and/or retain the cushion component on the platform.
