Abstract

See full text

The disclosed method for fabricating low cost laryngeal mask devices includes providing a mold, the mold including interior walls that define a hollow interior volume. 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 liquid plastic material and then allowed to cure. The cured plastic material is then removed from the mold and the cured plastic material includes a generally elliptically shaped plate and a cuff. The cuff is formed from plastic material that coated the portion of the interior walls that defined 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.
