A mask is disclosed that has a gas outlet which is quiet and provides for a diffused outlet flow of gases. The outlet is preferably a slot formed between a hollow body and cover over said hollow body. The mask also preferably extends and seals under a user's chin in use.

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.

Systems and methods producing a customised patient respiratory interface are disclosed. Data representative of one or more landmark features of a head of a human is obtained. One or more landmark feature locations of the landmark features are identified based on the data. A set of manufacturing specifications for production of the patient respiratory interface component is determined based on the one or more landmark feature locations. The patient respiratory interface component is produced based on the set of manufacturing specifications.

A method of manufacturing a patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to the patient's airways includes collecting anthropometric data of a patient's face. Anticipated considerations are identified from the collected anthropometric data during use of the patient interface. The collected anthropometric data is processed to provide a transformed data set based on the anticipated considerations, the transformed data set corresponding to at least one customised patient interface component. At least one patient interface component is modelled based on the transformed data set.

Embodiments of the present invention may exist as a machine for continuous positive airway pressure, otherwise known as a “CPAP machine” in the art. The CPAP machine of the present invention may comprise a casing and plurality of working parts, the working parts including but not limited to a blower fan, one or more batteries, and a circuit board. All of the working parts may be housed within the casing, which allows the CPAP machine to exist as one compact unit that can be easily worn by a user without use of a hose, tube, external wire, or other component used to connect a component of a CPAP machine to the portion of a CPAP machine that is worn on, over, or in front of a user's face.

A patient interface includes a seal forming portion, a pad, and a cushion. The seal forming portion may have a base surface and a plurality of fibers fixed to and extending away from the base surface for contacting a patient's skin. The cushion may have at least along a portion of the circumference a first structure having an elongate section joined with at least one end section oriented substantially perpendicular or at an angle to the elongate section. A first end A of the elongate section may be connected or connectable to a frame member. The end section may be provided at an opposing second end B of the elongate section. The pad may have a resilient foam material layer with the seal forming portion. The pad may be adapted to be connected to the cushion.

A face mask including a base model of a mask body having a front side and a back side and defining an interior. The back side includes a face opening within which a portion of a user face including a nose and mouth can be inserted and encompassed. The face opening is defined by a perimeter and is modified to substantially correspond to contours of the user face based on scan of topographical facial features of the user face.

An apparatus including a patient interface device formed from a flat substrate that is folded, wherein the patient interface device includes a plurality of seams where sections of the substrate are joined together, and wherein one or more of the plurality of seams form a shape that corresponds to a perimeter of a bottom side of a nose from a first alare corner of the nose to a tip of the nose to a second alare corner of the nose.

A patient interface including a seal-forming structure with a textile membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patients nares and/or an entrance to the patients mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patients respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.

A facemask configured to be used by multiple sized/shaped heads can include a primary, a secondary and a tertiary seal. In some embodiments, the primary seal is contact with the nose and cheek regions; the secondary seal is in contact with the chin region; and the tertiary seal is in contact with the cheek and chin regions. In some embodiments, the tertiary seal extends inwardly and outwardly when applied to the face. In some embodiments, the mask includes test scissors.
