Abstract
A mask for supplying gas under pressure to the nasal airway of a human includes a series of flexible stretchable straps formed from an elastomeric material for locating the mask against the human face. The straps are integrally formed or joined to define a perimeter enclosing an aperture adapted to fit around the nasal area of a human. The straps are configured to approximate to the three dimensional shape of the region around the nasal area of the human face as they arm stretched, to form a tight fitting seal. The mask may be used with or without a manifold.
Claims27
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.
A harness for supplying gas under pressure to a nasal airway of a human, including:
- a series of flexible stretchable straps formed from an elastomeric material for locating the harness 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 a nasal area of a human face;
- and
- a means for supplying a flow of gas directed generally towards the perimeter of the harness 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 contours of the nasal area of a human face so that the straps anchor the harness to a human face relatively tightly.
A mask for supplying gas under pressure to a nasal airway of a human, including:
- a series of flexible stretchable straps formed from an elastomeric material for locating the mask against the human face, the straps being integrally formed or joined to define a perimeter enclosing a generally triangular 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 a nasal area of a human face and to define a face contacting portion and a non-face contacting portion on an opposite side of the straps to the face contacting portion;
- and
- at least two flexible arms extending away from the perimeter wherein the arms and perimeter are integrally formed from an elastomeric material;
- 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 the manifold is also formed from the same elastomeric material as the straps;
- wherein stretching of the straps around the nasal area of a human causes the straps to mould 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.
