Abstract: An integrated respiratory pressure therapy device and humidifier for pressurising and humidifying breathable air to treat a respiratory disorder in a patient, includes a blower configured to pressurise the breathable air; a water reservoir configured to hold a volume of water to be used for humidification of the breathable air, the water reservoir comprising a water reservoir base, a water reservoir lid connected to the water reservoir base, and a compliant portion. The compliant portion is constructed from an elastomeric material and configured to seal between the water reservoir base and the water reservoir lid. A water reservoir dock forms a cavity configured to partially receive the water reservoir. The water reservoir lid includes a protrusion and the water reservoir dock includes a recess configured to releasably engage one another to secure the water reservoir to the water reservoir dock.

Abstract: A flow regulating valve for a respiratory treatment system is disclosed, as well as a vent arrangement comprising the flow regulating valve. The flow regulating valve may include an inlet, an outlet, and a variable conduit in fluid communication with the inlet and the outlet. The variable conduit may include a movable portion that may move to vary an impedance of the variable conduit, thereby regulating a flow rate of the air travelling through the variable conduit. Advantageously, the flow regulating valve may thus reduce wastage of air (e.g. humidified air) that is exhausted from a respiratory treatment system, while maintaining sufficient washout of air.

Abstract: A respiratory pressure therapy (RPT) device is disclosed for treatment of respiratory-related disorders. The RPT device includes a pressure generator, a pneumatic block, a chassis and a device outlet for delivering a supply of flow of gas to a patient interface. The RPT device also comprises a humidifier including a water reservoir.
