Abstract
A laryngeal mask assembly has an elliptical mask portion at the patient end of a tube. The mask portion has a mount attached to the tube and a cuff extending around the periphery of the mount. The patient end of the tube opens into the center of the mount, which has three lateral ribs projecting forwardly and extending parallel and spaced from one another. The forward end of the ribs have a concave profile with rounded projections at each end. The ribs act to hold the epiglottis away from the tube opening during insertion of the assembly and to provide an air passage into the tube.
