Abstract
An airway has a ventilation tube with a mask attached to its distal end. The mask has a base and a sealing ring surrounding the base. The sealing ring has an exterior side surface extending around the base, an upper surface extending from the exterior side surface toward a center of the base, and an inner surface extending from the upper surface toward the center of the base. The exterior surface, upper surface, and inner surface define an inner volume within the sealing ring. The sealing ring and base define a cavity in the mask. An evacuation tube is attached to a proximal end of the mask and extends through the inner volume of the sealing ring to a distal end of the mask where it forms an opening on the mask distal end on the sealing ring exterior side surface.
