A headgear assembly includes a strap of a first flexible material with an elongate edge, and a second flexible material folded around and running along the elongate edge. The second flexible material may be an elastic material. The second flexible material may also cover an intersection or joint in the first flexible material such that the first flexible material may be made from two flexible materials layered together or joined end to end.

A method of generating a customized headgear that includes a plurality of physical features and being usable with a mask component that supplies a flow of breathing gas to the patient's airways. The method includes receiving one or more parameters pertaining to the patient's head, subjecting at least some of the parameters to one or more algorithms to determine at least one of a length of a physical feature of the plurality of physical features and an angle between a pair of physical features of the plurality of physical features, generating an outline of at least a portion of a body which, when formed, is usable to assemble therefrom at least a portion of the headgear, and outputting a pattern usable to enable the formation of the at least portion of the body from at least a first sheet of at least a first material.

A patient interface for respiratory therapy includes a nasal interface having nasal prongs configured to contact nares of the user and form a seal. The patient interface also includes a securement portion having a pair of facial pads, each of the facial pads configured to engage the face of a user on opposing sides of the nasal interface. The facial pads are coupled to the bridging portions configured to urge the nasal interface toward the user's face to create or maintain sealing engagement between the nasal interface and the user's face. In some configurations, the securement portion and the nasal interface are detachably coupled to each other.

The present technology relates to a headgear for a patient interface, comprising one or more straps each having a first end for connecting to a mask. The first end of each strap comprises a connection portion which is grippable by a user to pull the strap to increase a tension in the strap, a first rigid member and a second rigid member that extends from a resilient carrier that is connected to the connection portion. The second rigid member is movable relative to the first rigid member when the connection portion is pulled. At least part of the second rigid member is arranged to strike the first rigid member to cause at least an audible alert when the second rigid member travels further than a threshold distance. The resilient carrier is constructed and arranged such that the threshold distance corresponds to a desired tension limit for the strap.

A system of breathing arrangements for delivering breathable gas to a patient includes at least first and second cushion components, e.g., full-face, nasal, nasal prongs, nose tip, and/or a combination of any of the above, including a nasal or full-face cushion and nasal prongs/nozzles combination, etc., that are different from one another in at least one aspect, and a common frame assembly configured to support each of the first and second cushion components. Various embodiments are directed to a full-face or nasal mask used with a frame having lateral connector portions having a stiffening member. The mask assembly may include a nose height adjustment device for the height of the cushion, or a cushion adjustment member by which the position of the cushion may be adjusted relative to the frame. The mask assembly may include a chin strap assembly.

A patient interface assembly includes a patient interface configured to deliver breathing gases to the airway of a patient. A headgear is configured to support the patient interface on the head of a patient. The headgear can include a tab on each side configured to overlie the patient's cheek and forming a portion or an entirety of an attachment region for the patient interface. The tab can be angled relative to an adjacent portion of the headgear. In some configurations, the headgear includes a rear portion having a first degree of stretch and/or a front portion having a second degree of stretch. In some configurations, the headgear also includes a chinstrap having a third degree of stretch. In some configurations, the third degree of stretch is greater than the first degree of stretch and the second degree of stretch.

The mask assembly may include a nose height adjustment device for the height of the cushion, or a cushion adjustment member by which the position of the cushion may be adjusted relative to the frame. The mask assembly may include a chin strap assembly.

A patient interface comprises a seal-forming structure including a textile membrane and a support structure to support the textile membrane. The seal-forming structure may have a varying construction in order to accommodate different regions and the varying contours of the patients face to ensure a robust and comfortable seal. An air impermeable layer of the textile membrane may have a thickness that varies in different portions of the textile membrane and/or different regions of the cushion assembly. Further, the seal-forming structure may include an underlying cushion, and an arrangement of the textile membrane and the underlying cushion and/or the configuration of the underlying cushion may vary in different regions of the cushion assembly to optimize patient comfort and the effectiveness of the seal in different regions of the patients face.

A seal-forming structure for a patient interface may include a patient-contacting surface configured to engage the patient's facial skin to form a seal; a posterior opening formed in the patient-contacting surface, the posterior opening configured to provide the flow of air at said therapeutic pressure to the patient's nares; and a support structure extending from the patient contacting surface to an interior surface of the seal-forming structure, the support structure and the interior surface forming a continuous loop, wherein the patient interface is configured to allow the patient to breath from ambient through their mouth in the absence of a flow of pressurised air through the plenum chamber inlet port, or the patient interface is configured to leave the patient's mouth uncovered.
