Patent abstract
A mask for the delivery of a medical gas under positive pressure. The engagement surface is generally circular in shape and is sufficiently rigid that operatively, when a suitable retention force is applied to the mask, an effective seal is produced at the interface of the engagement surface and the surrounding tissue primarily by deformation of the surrounding tissue.
