Tracheostomy Tubes This set comprises seven tracheostomy tubes, each including an outer cannula, an inner cannula, and a faceplate. The tubes feature a curved, hollow body. One end is adorned with a rectangular piece, known as the faceplate. The inner cannula is designed to fit snugly into the outer cannula, and a small latch secures them together at the faceplate. All tubes bear the maker’s mark ‘Fannin Ltd.’, and the larger ones are marked ‘Made in England’ and ‘Silver’. Each tube is labelled with a size marker; two tubes are ‘36’, one is ‘20’, two are ‘18’, and two are ‘16’. Tracheostomy tubes are used to create an opening into the trachea through the neck. 1925-1975
