摘要：
An inner cannula (3) of a tracheostomy tube (1) has a wall (33, 133) mainly of ePTFE and a reinforcing rib (34, 134) extending along the length of its shaft (30). The rib (34, 134) is of a thermoplastic and is mechanically retained with the wall (33, 133) by flow of the ePTFE around the rib or through recesses (140) in the rib.
