  • Method of manufacturing a neck flange
    Patent number: 6284179
    Abstract: A neck flange supports a tracheostomy tube inserted into the neck and has a neck engaging portion of a molded thin flexible flat sheet of a transparent polymer. An interconnection positioned centrally within the neck engaging portion and carried thereby has a ring shaped body with an opening and a pair of opposed pivot pins extending inwardly into the opening for carrying the tube passing therethrough. The pair of opposed pins fit for movement within recesses in the tube to permit limited swivel motion. The interconnection is molded of a transparent polymer material that is less flexible than the neck engaging portion and has a stepped cross section so the pair of opposed pivot pins are raised relative to the ring shaped body. The neck engaging portion is molded about the interconnection so the raised pair of opposed pins remain exposed.
