Abstract
A tracheostomy tube has a sealing cuff inflated by an inflation tube extending in a channel along one side of the tracheostomy tube. A suction tube extends in a channel along the opposite side of the tracheostomy tube. The suction tube extends to the upper end of the sealing cuff and 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.
