TRACHEOSTOMY TUBE ASSEMBLIES, INNER CANNULAE AND METHODS OF MAKING INNER CANNULAE

摘要

The tracheostomy tube assembly of inner sleeve (20), including thin, inner sheath (22) support structural frame (23) in outside by multiple ribs with longitudinal portion (25) and (26) circumferentially extending spaced apart, and along the casing. Insertion in inner sleeve (20), and can be from outer tracheostomy tube (1). Inner sleeve (20) is made up on modeling core of coating and forms sheath, then sheath bend core. Structural framing (23) is then molded in sheath (22) in mold 80.
