Abstract

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.

Claims

1. A mask assembly for a user comprising:

a frame;

a cushion component provided to the frame and defining a breathing cavity configured to accommodate at least a portion of the user'"'"'s nose in use, said cushion component including a face contacting seal portion adapted to sealingly engage with at least a portion of the user'"'"'s nose in use, said cushion component having an aperture to communicate pressurized gas from the breathing chamber to the user'"'"'s airways in use and a main wall portion, opposite from the aperture, extending upwardly away from the frame; and

a chin strap assembly including an extension member provided to each side of the frame and a chin strap having a main chin support portion and straps coupled to the extension members.

2. The assembly of claim 1, wherein the chin strap includes at least one portion bonded to a portion of the frame or cushion component.

3. The assembly of claim 2, wherein the at least one portion of the chin strap is bonded by adhesive bonding, lamination or plasma bonding.

4. A mask assembly for a user comprising:

a common frame;

a cushion component provided to the frame and including a pair of nasal prongs or nozzles adapted to engage the user'"'"'s nares in use; and

a supplemental cushion component in the form of a nasal cushion or a full-face cushion,

wherein the cushion component and the supplemental cushion component cooperatively seal with the user'"'"'s face in use.
