A method of making a laryngeal airway comprising an inflatable positioning shield 22 having a base 42 and an inflatable, hollow peripheral portion 40. The method includes introducing at least one molding material onto internal walls (56 Fig 2) of a mold (52 Fig 2), wherein the mold has a cavity (54 Fig 2) defined by internal walls that conform to the external wall of the laryngeal airway, and wherein only a sufficient amount of the molding material is introduced onto the internal walls of the mold that is necessary to create external walls of the laryngeal airway having a desired thickness and allowing the molding material to cure about the internal walls, thereby forming laryngeal mask. The base may have a respiratory tube 26 and be inserted into the mould prior to the introduction of the moulding material which may be polyvinylchloride. A later embodiment relates to a method of making a laryngeal airway with an inflatable positioning shield and a respiratory tube. |
