Abstract: A patient interface comprises a plenum chamber and a seal-forming structure. The seal-forming structure comprises a support structure arranged to support a sealing portion that is adapted to sealing engage the patient's face in use. The seal-forming structure may also include a seal biasing portion configured to inflate under pressurization within the cavity in the cushion assembly in use to extend the reach of the sealing portion and decouple the sealing portion from external forces.

Abstract: A patient interface structure includes a cushion configured to sealingly engage the patient's face and a front that is more rigid than the cushion. The cushion includes a forward opening, a rearward opening that is opposite the forward opening and a continuous sealing surface. The continuous sealing surface has a mouth sealing portion configured to seal around the patient's mouth and a nasal sealing portion configured to seal around both of the patient's nasal airways. The front plate includes an air inlet configured to both receive the pressurized respiratory gas and secure headgear to the patient interface structure. In addition, the nasal sealing portion includes at least one aperture that is separate from the rearward opening. Also, the front plate, the mouth sealing portion and the nasal sealing portion together form a common chamber.

Abstract: A mask for use at an operating pressure substantially equal to atmospheric pressure includes a body with a three-dimensional shaped chamber that is configured to receive a user's mouth and nares and operate at the operating pressure. The mask also includes a nose portion having an uppermost portion sized to avoid contact with the user's nasal ridge and to contact the user's nose along the user's sagittal plane and around at least a portion of the user's nares on an inferior side of the user's nose inferior to the user's nasal ridge. The nose portion is constructed from an at least partially impermeable material to limit airflow toward the user's eyes in use. The mask also includes a positioning and stabilising structure to provide a force to hold the seal forming structure in position against the user.

Abstract: A patient interface including a seal-forming structure with a textile membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patient's nares and/or an entrance to the patient's mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patient's respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.

Abstract: A breathing arrangement includes a patient interface, at least one inlet conduit, and a headgear assembly. The patient interface includes a mouth covering assembly including a cushion structured to sealingly engage around exterior of a patient's mouth in use, a nozzle assembly including a pair of nozzles structured to sealingly engage within nasal passages of a patient's nose in use, and a flexible element connecting the mouth covering assembly and the nozzle assembly. The at least one inlet conduit is structured to deliver breathable gas into at least one of the mouth covering assembly and the nozzle assembly for breathing by the patient. The headgear assembly is removably connected to at least one of the mouth covering assembly and the nozzle assembly so as to maintain the mouth covering assembly and the nozzle assembly in a desired position on the patient's face.

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 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 at least one gas delivery tube may be 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. 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. The positioning and stabilising structure may comprise a bias mechanism to impart a biasing force along at least a part of a length of the at least one gas delivery tube to urge the seal-forming structure towards the entrance of the patient's airways in use.
