Abstract
A tracheostomy tube assembly comprises an outer tracheostomy tube () and an inner cannula () fitted in the tube. The machine end of the inner cannula has a collapsible region () formed by a plurality of curved or bent struts () extending parallel with one another between a machine end collar () and a patient end collar (). The struts () carry outwardly-projecting catches () arranged to engage a rib () extending around the inside of a hub () at the machine end of the tube and thereby resist removal of the cannula from the tube. The inner cannula () is removed by twisting the machine end collar () so that the struts () collapse inwardly and thereby disengage the catches () from the rib ().
