    摘要： A patient interface including a positioning and stabilizing structure that is configured to maintain a first seal-forming structure and a second seal-forming structure in a therapeutically effective position. The positioning and stabilizing structure comprises a frame coupled to the plenum chamber. The frame includes a central portion coupled to the plenum chamber outside of the cavity. The frame also includes a pair of arms that extend away from the central portion in a posterior direction past the second seal-forming structure. The pair of arms are more flexible than the central portion. The positioning and stabilizing structure also includes headgear straps coupled to the frame, which configured to provide a tensile force to the first seal-forming structure and to the second seal-forming structure into the patient's face via the frame.

    摘要： A positioning and stabilising structure comprising at least one gas delivery tube to receive the flow of air from a connection port on top of the patient's head and to deliver the flow of air to the entrance of the patient's airways via the seal-forming structure, the at least one gas delivery tube comprising a tube wall having an extendable concertina structure comprising a plurality of folds in the tube wall alternatingly forming a plurality of ridges and a plurality of grooves, the folds able to be at least partially unfolded to increase a separation of the ridges to elongate the extendable concertina structure; and one or more ridge connecting portions provided to the tube wall, each of the one or more ridge connecting portions connecting two or more adjacent ridges of the plurality of ridges and being configured to resist the separation of the ridges.
