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 ().

A suction control valve for a closed system suction catheter has a housing with an inlet bore and an outlet bore inclined at an angle to the inlet bore and opening into the bore via an aperture. A valve member comprises a rod member and a manually actuable plate extending longitudinally in an external channel along the housing between two walls. The rod member supports a resilient sleeve and its forward end is urged, by a spring, to engage a tapered seal within the housing forwardly of the aperture, thereby blocking flow through the valve. The valve is opened by sliding the plate rearwardly so that the valve member moves rearwardly of the aperture. A locking cap can be twisted to prevent movement of the valve member from its closed position.
