Abstract: A mask cushion or a mask assembly therewith provides a comfortable and effective seal for provision of a gas therapy by a respiratory treatment apparatus. The mask cushion (102) may be integrated with or coupled to a mask frame. The mask cushion typically includes an inner cushion component (104). The mask cushion also includes a patient facial-contact side portion with a chamber (108) and a barrier (106) to form the chamber that may be flexible. The chamber may serve as an outer layer with respect to the inner cushion component. The chamber may be partially or completely filled with a gas, fluid or gel. The inner cushion may be formed with a soft flexible material such as an elastomer or foam, etc. The barrier may be a membrane and may also be soft flexible material.

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.

Abstract: A patient interface is configured to deliver a flow of pressurized breathable gas to a patient's airways. The patient interface includes a central portion with an opening configured to deliver the pressurized breathable gas to the patient's nares. A first stabilizing portion extends from the central portion and is structured to engage an outer side of a respective one of the patient's nostrils. A second stabilizing portion is opposite the first stabilizing portion and extends from the central portion. In addition, the second stabilizing surface is structured to engage an outer side of a respective one of the patient's nostrils. The central portion, the first stabilizing portion and the second stabilizing portion cooperate to form a U-shape configured to cradle the patient's nose so that the tip of the patient's nose remains exposed when the patient interface is mounted on the patient's face.

Abstract: A mask assembly for treating sleep disorder including: a first frame including a first wall that at least partially delimits a breathing chamber, a second wall surrounding an opening through the first wall and defining a first substantially cylindrical surface surrounding the opening, the second wall extending from the first wall, the opening allowing the flow of pressurized gas to the breathing chamber; a second frame including a third wall defining a second substantially cylindrical surface, a fourth wall, a member extending toward a forehead support and two headgear attachment locations, the third wall extending from the fourth wall, the second cylindrical surface at least partially overlapping with the first cylindrical surface, and the second frame being configured to removably interlock with the first frame proximate the opening; and a cushion molded to the first frame and adapted to seal around at least a patient's nose.

Abstract: An elbow for a respiratory mask includes a mask connection end adapted to connect to the mask and a tube connection end adapted to connect to an air delivery tube that delivers breathable gas to a patient. The mask connection end includes a first region constructed of a more rigid material and a second region constructed of a more flexible material. The second region provides flexibility to one or more portions of the mask connection end to enable engagement and disengagement of the elbow with the mask and/or sealing of the elbow with the mask.

Abstract: A PAP system includes a PAP device to generate a supply of pressurized air, a patient interface adapted to form a seal with the patient's face, air delivery tubing to interconnect the patient interface and the PAP device, and a cover that substantially encloses at least a portion of the PAP device and a portion of the air delivery tubing. The cover allows the PAP device to be carried by and/or supported on the patient's head.

Abstract: A device provides respiratory treatment such as for sleep disordered breathing and other respiratory conditions in a discreet configuration to provide a minimally invasive system.

The cushion is structured to compensate for variations in strap tension, treatment pressure and/or movement of the patient. Headgear may be provided with a strap assembly in which one or more straps is provided with selectively adjustable elasticity or extensibility that may be automatically changed in dependence of treatment pressure and/or treatment type.
