Abstract

The present inventions seeks to address problems of the prior art relating to comfort, cost, efficacy, ease of use and manufacturability. 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.
