A headgear assembly includes a first arm member and a second arm member each having a first end and a second, opposing end. The first end of the first arm member has a structure sized and configured to engage a first rotation-resistant coupling of a frame in a manner which prohibits rotation of the first arm member with respect to the frame in a first plane in which the first arm member is located. The first end of the second arm member has a structure sized and configured to engage a second rotation-resistant coupling of the frame in a manner which prohibits rotation of the second arm member with respect to the frame in a second plane in which the second arm member is located. The assembly further includes a strap member coupled to the first and second arm members.

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 patient's 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 patient's face.

A respiratory pressure therapy system for providing continuous positive air pressure to a patient via a patient interface configured to engage with at least one airway of the patient. The system includes: a flow generator configured to generate supply of breathable gas for delivery to the patient via the patient interface; at least one sensor; a display; and a computing device. The computing device is configured to: receive sensor data that is based on measured physical property of the supply of breathable gas; control, based on the received sensor data, the flow generator to adjust a property of the supply of breathable gas; receive, an input indicating assistance is needed with using the patient interface; receive one or more images of the patient with the patient interface; analyse the received one or more images; and based on the analysis, display instructions for positioning the patient interface.

A customizable mask including a conforming seal is configured to utilize the physical process of granular jamming to enable it to adapt to a wide range of facial geometries. The mask may include a frame having a perimeter and a conduit connection, a conforming seal positioned along the perimeter of the frame. The conforming seal may include a sealing surface and a connecting surface, the connecting surface configured to mate with the perimeter of the frame, and the sealing surface configured to conform to a users' face. The conforming seal may further include an outer casing, granular material contained within the outer casing, and a vacuum connection. The mask may also include a similarly configured conforming frame. Further disclosed are methods of forming such masks.

A method of manufacturing a cushion for a respiratory mask includes providing a mold with at least two mold halves and at least one core therein, closing the mold, and injecting a first material into the mold to form the cushion. The at least one core is enclosed by the cushion thereby forming at least one cavity. The method also includes opening the mold, removing the at least one core from the cushion to provide the at least one cavity within the cushion, and sealing the cavity. The cushion includes a support plane configured to be supported on the patient's face in use. The at least one core is arranged in the cushion with a C-shape on a plane substantially parallel to the support plane.

A system for determining an optimal hardness of a patient interface device includes a fit score determination unit structured to receive a 3-D model of the patient interface device and a 3-D model of a patient's face and to determine a fit score between the patient interface device and the patient's face based on the 3-D model of the patient interface device and the 3-D model of the patient's face, and a hardness determination unit structured to determine a hardness value of the patient interface device based on the determined fit score.

A support member for use in a sealing assembly of a patient interface device for delivering a flow of a breathing gas to the airway of a patient. The support member includes: a first end structured to be coupled to a frame member of the patent interface device; a second end structured to sealingly engage the face of a patient or to underlie a sealing flap which is structured to sealingly engage the face of a patient; and a sidewall which extends between the first end and the second end. The sidewall is formed from a plurality of beads of material.

A cushion/frame assembly for a patient interface includes a cushion frame and a cushion. The cushion frame includes a cushion frame material, an annular wall portion having an opening that extends along a cushion frame longitudinal axis, and a projection extending radially with respect to the opening. The cushion frame is configured to snap fit with an outer frame having headgear attachment points and being configured to engage an inlet conduit. The cushion is connected to the cushion frame. The cushion is structured to form a seal with the patient and includes a cushion material that is more flexible than the cushion frame material.

A system for detecting manual ventilation and selectively delivering a high flow of oxygen. The system comprises a source of compressed oxygen coupled to a first lumen of a nasal cannula, with an oxygen flow control valve coupled to a processor to control the flow of oxygen to the nasal cannula. A second lumen of the nasal cannula is in connection with a pressure sensor and the pressure sensor in connection with the processor. The processor may receive the pressure values and be programmed to determine when manual ventilation has occurred, and send a signal to the oxygen flow control valve to send a high flow of oxygen in response to manual ventilation.

Forms of the technology provide a patient interface for supplying a flow of air at a therapeutic pressure to a patient's airways. The patient interface may comprise a cushion module comprising a cushion, wherein the cushion is constructed and configured to be substantially flexible, and may further comprise a brace. The brace may be configured to mount to a nasal portion of the cushion and, in use, to brace against movement of portions of the seal-forming structure in sealing engagement with regions of the patient's face proximate the patient's nares. Additionally, or alternatively, when the brace is mounted to a nasal portion of the cushion module, the nasal portion may be deformed relative to a natural shape of the nasal portion.
