Abstract: A blower includes a housing including an inlet and an outlet, a stationary component provided to the housing, an impeller positioned between the inlet of the housing and the stationary component, and a motor adapted to drive the impeller. The stationary component includes a tube portion structured to retain and align a pair of bearings that rotatably support a rotor to which the impeller is coupled. The tube portion includes a diameter in a side closest to the impeller that is sufficient size to accommodate adhesive to retain one of the bearings.

Abstract: A method for controlling a humidifier of a CPAP device including a controller, the method including controlling a heating element in the humidifier with command signals from the controller, sensing a temperature of a fluid in the humidifier with a sensor in the humidifier that transmits signals to the controller, establishing an acceptable operating range for the signal transmitted to the controller, determining whether the transmitted signal is within the acceptable operating range, if the signal is within the acceptable operating range treating the signal as being indicative of the temperature of the fluid in the humidifier and using the signal to control the heating element, and if the signal is outside of the acceptable operating range, the controller determines the humidifier to be unavailable.

Abstract: A patient interface includes a mask configured to communicate with at least one airway of a patient, the mask including at least one aperture (402) configured to deliver gas to the at least one airway of the patient; and an airflow resistance member (400) provided to the mask to control the airflow through the at least one airway.

Abstract: Systems, devices and methods of use adapted for treatment of respiratory disease or sleep disordered breathing include a patient interface (10) adapted to be secured to and sealed against a portion of a patient's face, in use. A flow generator is adapted to be connected to the patient interface and to be secured by a portion of the patient's body. The flow generator includes a blower (50) adapted to provide pressurised breathable gas to a patient through the patient interface. The blower is adapted to be at least partially vibrationally isolated from the patient's body by at least one dampening system (49) or device. The dampening device or system is adapted to reduce the amount of transmitted vibration received by the patient. A PAP system includes a patient interface including sealing arrangement (30) adapted to form a seal with the patient's nose and/or mouth and headgear (40) to support the sealing arrangement in position on the patient's head.

Abstract: A CPAP system includes a PAP device (5) structured to generate a supply of pressurized air, a patient interface (15) adapted to engage with the patient's face to provide a seal, an air delivery conduit (102,104) provided between the PAP device and the patient interface to deliver the supply of pressurized air along a gas delivery path from the PAP device to the patient interface, and a muffler (100) provided along the gas delivery path downstream of the PAP device.
