Patent ID: 6886564

Claim:
A mask for supplying gas under pressure to the nasal airway of a human, including: a series of flexible stretchable straps formed from an elastomeric material for locating the mask against a human face, the straps being integrally formed or joined to define a perimeter enclosing an aperture adapted to fit around a nasal area of a human, the straps being shaped and configured to approximate to a three dimensional shape of a region around the nasal area of a human face; and defining a face contacting portion having a non-face contacting side; and a manifold disposed on the non-face contacting side of the face contacting portion, the manifold including means for connection to a gas supply means; wherein stretching of the straps around the nasal area of the human causes the straps to mould to the contours of the nasal area of the face so that the straps form a seal around the nasal area which is a relatively tight fitting seal.
