Abstract: A vent system for use during respiratory therapy with a flow of pressurized gas may provide a continuous vent flow of gas. The vent system may include a vent housing having an outer wall; an inner wall, the inner wall defining an inlet for the flow of gas; and a base positioned between the outer wall and the inner wall, the base having at least one first orifice and at least one second orifice. The vent system may include a membrane, the membrane being shaped and dimensioned such that the membrane does not cover the at least one first orifice to allow the vent flow through the at least one first orifice, and the membrane being shaped and dimensioned such that in a first position the membrane is positioned over the at least one second orifice to allow the vent flow through the at least one second orifice.

Abstract: A vent system for a respiratory therapy system may include: a vent housing comprising a base having a first orifice extending through the base to allow a vent flow of gas to be discharged to atmosphere to discharge gas exhaled by a patient from a pressurized volume, the vent flow of gas being continuous during respiratory therapy; a second orifice to allow gas to be discharged to atmosphere; a vent housing connector having an outlet opening; a heat and moisture exchanger (HME) having an HME housing and an HME material within the HME housing; and an elastically deformable membrane positioned adjacent to the base to apportion the vent flow of gas between the first orifice and the second orifice; the vent housing and the vent housing connector being configured to be connected to form a cavity, and the HME being positioned in the cavity.

Abstract: A humidifier comprises a water reservoir and a reservoir dock configured to receive the water reservoir in an operative position. The water reservoir is configured to hold a volume of liquid. The water reservoir includes a chamber and a single conduit providing an inner opening arranged within the chamber. The reservoir dock includes a dock inlet conduit arranged to receive the flow of air from the RPT device. The dock inlet conduit is structured and arranged to extend within the single conduit of the water reservoir when the water reservoir reaches the operative position such that the dock inlet conduit and the single conduit at least partially overlap one another.

Abstract: A vent adaptor for a for a respiratory pressure therapy (RPT) system, the vent adaptor comprising: a vent assembly comprising: a vent housing defining a central orifice for the flow of pressurized gas to pass through the vent assembly from the delivery conduit to the patient interface, the vent housing having an annular surface around the central orifice, and the annular surface having a plurality of holes to discharge pressurized gas to atmosphere; and a membrane positioned adjacent to the annular surface; a heat and moisture exchanger (HME); and a diffusing member.

Abstract: A water reservoir configured to be removably connected to a respiratory pressure therapy (RPT) device has a water reservoir base configured to hold a volume of water to be used for humidification of the breathable air, a water reservoir lid connected to the water reservoir base, a retainer configured to engage with a corresponding portion of a water reservoir dock associated with the RPT device, thus securing the water reservoir to the water reservoir dock, and a portion of the lid being configured to receive a downward force to cause movement of the retainer against the bias of a spring, thus allowing removal of the water reservoir from the water reservoir dock.

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 an integrated humidifier including a water reservoir. An RPT device is also disclosed that includes a wireless data communication interface integrated with the housing and configured to connect to another device or a network.

Abstract: Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The seal-forming structure may be constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways for sealed delivery of a flow of air at a therapeutic pressure of at least 4 cmH2O with respect to ambient air pressure throughout the patient's respiratory cycle in use. The positioning and stabilising structure may comprise at least one gas delivery tube to deliver the flow of air to the entrance of a patient's airways via the seal-forming structure. The positioning and stabilising structure may comprise an adjustment mechanism for adjustment of a length of the at least one gas delivery tube to enable the positioning and stabilising structure to fit different size heads.
