Conventional tracheostomy tubes have a sealing cuff inflated by an inflation lumen extending along the tube. The tube may also have a suction lumen opening just above the cuff to enable collected secretions to be removed. In the present invention the tracheostomy tube is moulded and has channels extending along opposite sides for a suction tube and an inflation tube. The suction tube opens into a recess on the outside of the tracheostomy tube through a side opening oriented at right angles to the radius of the tracheostomy tube. The recess extends around about 90° of the tube towards its outer curve so that secretions collecting in this region can be removed.
