Abstract
A patient interface for treating sleep disorder breathing includes a headgear tube that provides support for the seal forming structure. The headgear tube includes a patient-contacting portion and a non-patient contacting portion that are joined along seams to form a gas passageway. The headgear tube may comprise a textile material and/or a foam material. Portions of the headgear tube may be imparted with greater rigidity than other portions.

A positioning and stabilising structure to provide a force to hold a seal-forming structure in a therapeutically effective position on a patient's head for positive pressure airway treatment of sleep disordered breathing, the positioning and stabilising structure comprising:
- at least one gas delivery tube to deliver a flow of air to an entrance of the patient's airways via a seal-forming structure, each gas delivery tube being constructed and arranged to contact, in use, at least a region of the patient's head superior to an otobasion superior of the patient's head, each gas delivery tube comprising a tube wall defining a hollow interior through which air is able to flow to the seal-forming structure, each gas delivery tube comprising:
- a patient-contacting portion configured to contact the patient's body, the patient-contacting portion comprising 1) a textile material and/or a foam material, and 2) an air-impermeable material provided to the textile material and/or the foam material to make the patient-contacting portion substantially air-impermeable;
- a non-patient contacting portion configured to be oriented away from the patient's body in use, the non-patient contacting portion comprising 1) a textile material and/or a foam material, and 2) an air-impermeable material provided to the textile material and/or the foam material to make the non-patient contacting portion substantially air-impermeable;
- and
- at least one seam to join the patient-contacting portion and the non-patient contacting portion,
- wherein the at least one seam comprises rigidising elements embedded within or layered on the seam to provide rigidity to the gas delivery tube.
