FIGS. 95-121B disclose a large variety of connectors connecting the headgear assembly to the mask assembly where the headgear, mask and connector form a closed loop the connector is disengaged with the mask assembly.

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: A medical tube has a tube wall, a first end and a second end. At least one heater wire is wrapped around the wall. Near or at one of the first end or the second end, there is at least one recess in an outer surface of the wall. The heater wire passes over the at least one tube recess such that the wire does not contact the wall in the area of the tube recess. Also disclosed are methods of making the tube and components used in making the tube.

Abstract: A method of patient management including receiving therapy data associated with a plurality of durable medical devices and a first set of patients, and displaying an overview of patient compliance and a plurality of customizable tiles. The overview of patient compliance includes at least the number of patients in the first set of patients, current compliance data, compliance history data, and follow-up data. The plurality of aligned tiles includes at least a title and a plurality of selectable subtitles, each of the plurality of selected subtitles associated with one or more rules. Upon selection of a first selectable subtitle, displaying at least an indication of patients in a second set of patients, wherein the second set of patients is a subset of the first set of patients; upon selection of a first patient, displaying at least all of the rules triggered by the first patient.

Abstract: A circuit connector for a humidification system, the system comprising a base unit configured to be engaged by a humidification chamber. The circuit connector comprises an inlet to fluidly connect to an outlet of the humidification chamber to receive humidified gases therefrom, an outlet to sealably connect to or integral with a conduit for directing the humidified gases to a user, and an electrical terminal for electrically coupling the circuit connector to an electrical terminal associated with the base unit. The circuit connector may be releasably and lockably connectable to the outlet of the humidification chamber and/or orientation features may control orientation of component parts of the system as they are assembled.

Abstract: There is provided a user interface comprising: a. a mask body; b. a sealing cushion connected to the mask body and configured to seal around a patient's nose and/or mouth; wherein the mask body and sealing cushion together define an interior chamber of the user interface; c. a breathing gas delivery inlet provided in the mask body and configured to receive a breathing gas flow from a gas source; and d. at least one non-sealing nasal prong in the interior chamber. The user interface further comprising a breathing gas flow director configured to split the breathing gas flow into two flow paths such that a portion of the breathing gas flow is delivered along a first flow path from the inlet into the interior chamber to pressurise the interior chamber, and such that a portion of the breathing gas flow is delivered along a second flow path from the inlet through the nasal prong.

Abstract: An interface for positive pressure therapy includes a mask assembly. The mask assembly includes a mask seal that is adapted to underlie the nose. The mask seal extends up the lateral sides of the nose. The mask seal has a primary seal below the nose and a secondary seal alongside the nose. The mask seal includes a rolling hinge that permits one portion of the mask seal to deform relative to another portion of the mask seal. In one configuration, the portion of the mask seal that underlies the nose is configured to deform relative to a lower portion of the mask seal.

Abstract: A directional lock or a headgear or interface assembly comprising one or more directional locks that include a catch arrangement for initiating or assisting in movement of a lock member of the direction lock. In some configurations, the catch arrangement assists movement of the lock member in only a portion of a range of travel of the lock member. In some configurations, the directional lock comprises a housing and a sleeve and the catch arrangement comprises a catch arm carried by the sleeve. The catch arm includes a catch end that contacts the lock member, which can be a lock washer in some configurations.

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, a substrate and a textile casing. The substrate and textile casing have retaining structures to attach the textile casings to the substrates and the substrates to each other.

Abstract: A respiratory mask includes a housing and a cushion or seal that seals on a user's face in use. An upper portion of the seal that is disposed on a user's nasal bridge in use can roll toward and/or over the outer surface of the housing to form a rolling bridge feature that adjusts to different nose sizes. As the rolling bridge rolls, an apex of the seal moves away from the user's face to adjust to larger nose sizes. The apex does not move downward and can move upward relative to a location of the apex in a neutral position of the seal.

Abstract: Breathable medical circuit components and materials and methods for forming these components incorporate breathable foamed materials that are permeable to water vapor and substantially impermeable to liquid water and the bulk flow of gases. The materials and methods can be incorporated into a variety of components, including tubes, Y-connectors, catheter mounts, and patient interfaces and are suitable for use in a variety of medical circuits, including insufflation, anesthesia, and breathing circuits.

Abstract: An electrically conductive plastic (ECP) material can be used to heat water in a reservoir of a respiratory humidifier to encourage heating and/or humidification of gases passing through the respiratory humidifier. The electrically conductive plastic material can at least in part overmould the base and/or walls of the chamber and/or the reservoir of the respiratory humidifier. The reservoir can also partially or fully be formed from the electrically conductive plastic material. Furthermore, the humidification system can be configured to create substantially equal or differential heating of water in the reservoir.
