Abstract
A tracheostomy tube assembly has a right-angle swivel connector connected to the machine end of a tracheostomy tube within which extends a liner. A fitment at the machine end of the liner has two annular collars between which several apertures open into the fitment. If the liner should be displaced rearwardly in the connector and the machine end of the liner becomes blocked, gas can flow through the apertures.
