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. A method for manufacturing the neck flange has the steps of molding a ring shaped interconnection of a polymer and molding a neck engaging portion about the interconnection by inserting the interconnection into a mold then molding the neck engaging portion thereabout. A method for using the neck flange has the steps of placing the tracheostomy tube in a patient's neck and swiveling the neck engaging portion relative the tube to conform to the neck, flexing the neck engaging portion to conform to the curvature of the neck and observing the condition of the neck under the transparent neck flange.
