ABSTRACT:
A laryngeal mask airway has a tube with a mask portion at its patient end, the tube opening into the center of the mask portion. The mask portion is formed by a mount attached to the tube and by a bag-shape cuff attached to the mount. The mount is formed with two laterally-projecting flaps defining a dumbbell-shape opening to the tube. The flaps deflect the epiglottis during insertion of the airway into the patient but can be deflected by a suction tube, or the like, inserted through the tube.
