Abstract: A headgear assembly for retaining a respiratory mask on a user's face includes arrangements or components that allow for variation in a size of the headgear assembly. In some configurations, the headgear assembly includes one or more hubs, each of which are configured to connect a top and rear strap together. The size of the headgear assembly can be determined by the size or configuration of the hub. In other configurations, the headgear assembly comprises one or more spacer elements within one or more straps of the headgear. The size of the headgear assembly can be determined by the size of the spacer element or a relative position between the strap and the spacer element.

Abstract: An interface and headgear assembly includes a headgear assembly. The headgear assembly has a first strap configured to connect to the interface. A crown strap can be adjusted along a length of the first strap. In some configurations, the crown strap has a first portion and a second portion that are adjustably connected. The crown strap can be removably connected to the first strap using bridge regions of the first portion and the second portion.

Abstract: A headgear portion or assembly for use in combination with a breathing apparatus in some configurations is at least substantially inelastic and is three dimensional in shape. The headgear portion or assembly can comprise a plastic core and a textile casing. The headgear, or part thereof, may also have integrally moulded labels, connectors, adjustment mechanisms and/or grips.

Abstract: The apparatus, method, and system disclosed relates to a headgear assembly for a respiratory system for the delivery of respiratory therapy to a patient. The headgear comprises a yoke at least partially formed from an elastomeric material. The yoke is configured to be stretched under tension to attach the yoke to the headgear assembly.

Abstract: A mask assembly can include a mask seal. In some configurations, the mask assembly can be configured to be fully positioned lower than a bridge of a nose of a face of a user and to provide an exposed bridge of the nose of the user. The mask seal can comprise a nasal region comprising at least one nasal opening, a first paddle on a first side of the nasal region and a second paddle on a second side of the nasal region. The first paddle is configured to contact one side of the nose of the user and the second paddle is configured to contact the other side of the nose of the user.

Abstract: The present invention relates to an apparatus for providing respiratory assistance to a user via a user conduit. The apparatus being operable in a humidifying mode and a non-humidifying mode, and includes a humidification chamber for containing an amount of water that can be located in an operating position in the humidifying mode and, optionally separate from the apparatus in the non-humidifying mode. The apparatus may also have an auxiliary flow path that can be activated in the non-humidifying mode and a powered device that heats water in the humidification chamber when the apparatus is in the humidifying mode.

Abstract: A cushion for a respiratory mask is provided. The cushion includes a face contacting portion, a non-face contacting portion and an intermediate region. The face contacting portion is formed from an open cell foam material and includes an opening to provide, in use, a source of breathing gas to a user's airways. The non-face contacting portion is formed from an elastomeric material. The intermediate region is formed between the face contacting portion and the non-face contacting portion. Open cells of the open cell foam material in the intermediate region are filled with the elastomeric material.

Abstract: The present invention relates to a humidification apparatus having a compartment that receives a removable humidification chamber. The apparatus has an actuator that can be operated by a user to move the humidification chamber from an operating position to a releasing position. In the operating position the humidification chamber is received by the humidification compartment and forms a portion of the flow path through the humidification apparatus. In the releasing position the humidification chamber is displaced outwardly from the operating position so that a user can more easily remove the humidification chamber from the apparatus.
