A seal between a laryngeal mask airway device and the entrance to the larynx, which is sufficient to overcome the danger of aspiration of regurgitated or vomited matter into the lungs, is provided by:- (a) making the airway tube 7 as a flexible metallic structure, or (b) magnetic or electromagnetic attraction of the mask 1, or (c) adhesive attachment of the mask around the larynx entrance, or (d) a spring clamp 2, 3, 4 or (e) making the airway tube 7 as a coiled tube, which can be drawn into a tighter curve by tensioning a cable running along the tube. <IMAGE> |
