PROBLEM TO BE SOLVED: To provide a low cost laryngeal mask that is improved in the geometric shape of the laryngeal mask, and a method for fabricating the low cost laryngeal mask.SOLUTION: A mold including interior walls that define a hollow interior volume is provided. The interior volume includes a first portion and a second portion. A liquid plastic material is introduced into the mold, and then the mold is moved so as to coat the mold's interior walls. The cured plastic material is then removed from the mold. The plastic material includes an elliptically shaped plate and a cuff. The cuff is formed from the plastic material coating the portion of the interior walls for defining the first portion. The plate defines a laryngeal side, a pharyngeal side, and a central aperture. An interior perimeter of the cuff is attached to the laryngeal side of the plate proximal to a perimeter of the central aperture. An outer perimeter of the cuff is attached to the laryngeal side of the plate proximal to an outer perimeter of the plate.SELECTED DRAWING: Figure 15B |
