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: 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.

Abstract: An apparatus for humidifying a flow of pressurised, breathable air includes varying a first pressure of the flow of breathable gas to vary a level of thermal engagement between the conductive portion of the reservoir and the heater plate, varying a height of the variable portion varies a level of thermal engagement between the conductive portion of the reservoir and the heater plate, use of a humidifier reservoir base component with a maximum water capacity substantially equal to the predetermined maximum volume of water of the humidifier reservoir or the use of intersecting inlet and outlet axes.

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.

Abstract: A fluid connector system includes a first end portion with a first opening, a seal portion extending around a periphery of the first opening, and a latching portion. The seal portion is fixedly mounted to the first end portion. The fluid connector system also includes a second end portion that has an inner tube with a second opening, a sealing surface that extends around a periphery of the second opening, and an outer tube. The sealing surface may engage the seal portion to form a face seal to breathing gas travelling along the direction of engagement between the first and second end portions. The outer tube includes a complementary latching portion that may engage with the latching portion and may be depressed into a cavity formed between the inner and outer tubes. The seal portion is axially recessed relative to the latching portion along the direction of engagement.
