A headgear for securing a mask to a user's face is described. The headgear requires a first load force to elongate the headgear and, when fitted to a user, applies a balanced fit force that substantially equals a load force applied to the headgear during respiratory therapy. In some embodiments, the headgear includes an elastic portion configured to provide a retraction force, a non-elastic portion configured to be inelastic in comparison to the elastic portion, and a restriction mechanism connected to the non-elastic portion and to the elastic portion. The restriction mechanism is configured to apply a first resistance force to the user's head on elongation of the headgear and a second resistance force to the user's head on retraction of the headgear.

Automatically adjusting headgear for patient interface

Headgear for a respiratory interface has multiple separate sections of material joined to form the headgear and different levels of resilient extensibility or stretchability in at least four different parts or straps of the headgear. The multiple separate sections of material can include a rear part, a pair of upper side straps, a pair of lower side straps, and a top strap.

Headgear

A mask assembly includes a mask interface and a headgear assembly. The mask interface includes a housing and a seal that seals around a user's nose and/or mouth in use. The headgear assembly secures the mask interface to the user's face in use. The headgear assembly can include a top strap, a rear section, and side arms. The top strap can be manually adjustable. The rear section can be temporarily expanded to allow for donning and/or doffing of the mask assembly. The side arms can be automatically adjustable.

Respiratory mask system

A nasal seal, mask or an interface assembly have a seal body defining a breathing chamber. A nasal port is provided in the seal body. The nasal port has a central portion straddled by a pair of lateral portions. The nasal port further has an upper edge and a lower edge. The upper edge defines an inwardly projecting portion within the central portion. The lower edge defines an inwardly protection portion within the central portion. Thus, the nasal port can be generally bean-shaped or bowtie-shaped. The mask can include a frame having a central portion that supports the seal and a pair of arm portions that extend rearwardly of the seal and are configured to connect to headgear. The central portion can be more rigid than the arm portions. The mask can be configured to reduce noise transmitted through a bias flow vent.

Nasal seal, mask and respiratory interface assembly

A seal assembly for a respiratory interface, the seal assembly comprising a seal portion configured to form a seal with at least a portion of a user's face, the seal portion comprising a bladder having an internal volume that contains a shear thinning material; and a volume adjuster for adjusting the internal volume of the bladder. Alternatively, the seal assembly comprising a frame; two nasal prongs connected to the frame, each prong comprising a seal portion configured to form a seal with a portion of the user's nares and a flow path extending through the seal portion for delivery of respiratory gas to a user's nare; wherein the seal portion comprises a bladder that contains a shear thinning material.

Respiratory interface

A patient interface has a single loop head strap and a mask for covering at least the nostrils of the user. The single loop head strap extends from the mask at either end. A short length of supple conduit is coupled to the mask by a swivel or ball joint to allow rotation of the conduit relative to the mask through different angles and orientations.

Frame with supporting arms and length adjustable strap

Welded headgear sections can be produced by using a weld tool having pins protruding from a weld region contact surface to deliver high-frequency electromagnetic energy to a weld region defined by overlapping top and bottom headgear straps. The pins fully penetrate the top strap and at least partially penetrate the bottom strap. The pins concentrate the electromagnetic energy to achieve a weld joint of acceptable weld strength and aesthetic appeal.

High-frequency welding for headgear

An interface includes a mask. The mask includes a frame and a seal supported by the frame. Headgear is connected to the mask. The interface includes at least one of (i) an adjustment mechanism that can be set to a use length for a loop defined by the mask and the headgear; and (2) a break-fit assembly that can selectively lengthen the loop defined by the mask and the headgear and return to the use length.

Headgear for patient interface

A headgear system and/or an interface assembly incorporating a headgear system that, in some configurations, is configured to transform from elasticated or 'stretchy' behavior to “inelastic” behavior at least in response to normal or expected forces encountered during the intended therapy. In some configurations, upon fitment to the head of a user, the system automatically adjusts toward or to an appropriate size. 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.

Headgear assemblies and interface assemblies with headgear

A respiratory mask system includes a mask interface and a headgear assembly. The headgear assembly is adjustable and comprised of an elastic portion, a non-elastic portion and a restriction mechanism configured to provide a force resisting movement of the non-elastic portion when the elastic portion is extended. There is a support beam coupled to the non-elastic portion and extending along a portion of the headgear that is curved along its longitudinal extent. In this way particular seal modules can be comfortably fitted to a user and any blow off force is mitigated. A particular example of the respiratory mask system includes provision for removable attachment between the seal and a mask frame, the mask frame and a yoke of the headgear; and between a conduit and the mask frame.

A respiratory mask system includes a headgear that, in use, secures the respiratory mask system to a patient's head. The headgear includes a pair of forehead straps that are coupled together by a forehead coupler to form a closed loop. The forehead coupler is removably connected to a frame of the respiratory mask such that the forehead straps remain in a closed loop. The pair of forehead straps can also be coupled together by positioning a male strap portion within an aperture of a female strap portion. The male strap portion has a free end that is configured to be received into the aperture. The male strap portion includes a plurality of notches that engage the aperture of the female strap portion and provide incremental adjustment. The free ends of the male and female strap portions have fasteners configured to engage the surface of the other strap portion.
