Mask assemblies, breathing circuits and related components include configurations for reducing condensation within the mask and/or inhibiting or preventing condensation from coming into contact with a user of the mask. The mask assemblies can incorporate heating elements (such as heating coils), insulating spaces or barrier layers.

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 breathing arrangement includes a patient interface, at least one inlet conduit, and a headgear assembly. The patient interface includes a mouth covering assembly including a cushion structured to sealingly engage around exterior of a patient's mouth in use, a nozzle assembly including a pair of nozzles structured to sealingly engage within nasal passages of a patient's nose in use, and a flexible element connecting the mouth covering assembly and the nozzle assembly. The at least one inlet conduit is structured to deliver breathable gas into at least one of the mouth covering assembly and the nozzle assembly for breathing by the patient. The headgear assembly is removably connected to at least one of the mouth covering assembly and the nozzle assembly so as to maintain the mouth covering assembly and the nozzle assembly in a desired position on the patient's face.

A mask includes: a mask body configured to define a space that covers at least one of a nose and a mouth of a subject; and a cushion member extending along a peripheral edge portion of the mask body. The cushion member includes: a first region that includes a portion that contacts a face of the subject when fitted; and a second region positioned between the first region and the mask body. A surface of the first region has a higher non-adhesive property than a surface of the second region, and the second region has transparency that allows the space to be seen through.

A sealing cushion for a respiratory mask assembly, the sealing cushion comprising a patient interface portion having a resiliently deformable sealing membrane for engagement with a patient’s face, and an aperture formed therein for receiving a nasal and/or mouth region of a patient’s face, the sealing membrane comprising a plurality of regions of different thicknesses, the plurality of regions comprising: a compliant nasal region (20) for engagement with the patient’s nasal bridge; a nasal support regions (25) disposed either side of the compliant nasal region for engagement with the sides of the patient’s nose; cheek support regions (30) extending from each of the nasal support regions for engagement at least with the patient’s cheeks, and a compliant base region (35) extending between the cheek support regions, wherein the sealing membrane in the nasal support regions has a greater thickness than in the cheek support regions, and wherein the sealing membrane in the compliant nasal region and the compliant base region has a lower thickness than in the cheek support regions and the nasal support regions.

The invention relates to a respiratory mask of modular construction. The main components are reduced to four parts and are provided by the mask body, the forehead support, the mask bead and the attachment piece. The design, according to the invention, of the outflow structure between mask body and forehead support makes apertures in the mask body unnecessary for this purpose. The strap coupling in the region of the mask body is made easier by a funnel-shaped guide structure such that it is possible in a simple manner even without seeing it.

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 mask assembly can include a mask seal. In some configurations, the mask assembly can be configured to be fully positioned lower than a bridge of a nose of a face of a user and to provide an exposed bridge of the nose of the user. The mask seal can comprise a nasal region comprising at least one nasal opening, a first paddle on a first side of the nasal region and a second paddle on a second side of the nasal region. The first paddle is configured to contact one side of the nose of the user and the second paddle is configured to contact the other side of the nose of the user.

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 positive pressure ventilation apparatus may include a positive pressure mask; a positive pressure source; and an exhalation filter. The positive pressure mask may include a mask body having a patient-contact perimeter and including a flexible concertinaed portion of uniform flexion continuously around the mask body. The flexible concertinaed portion may include a plurality of ridges. The positive pressure mask may further include a gas inlet to the mask body configured to be connected to the positive-pressure source; and an adhesive seal positioned at the patient-contact perimeter which may be positioned at the outermost portion of the patient contact perimeter. The adhesive seal may comprise one or more layers. Each layer may include one or more cover members, each of which may include at least one removable tab; and at least one perforation. Each layer may further include a dual-sided form carrier with adhesive material on one or both sides.
