Abstract
The present invention is an inflatable cuff type anesthesia mask with three methods of improved support shell orientation of the inflatable cuff in combination with and to enable the successful operation of the mask at a point substantially more inferior on the bridge of the nose than currently shown in the prior art. In addition, the face directed inner edge of the support shell/cuff attachment forms a novel outline for improving the gas tight seal on the human face.
