Abstract
A tracheal tube has an extruded suction lumen extending along its length on the outside of the curvature of the tube. The suction lumen opens internally to the main lumen through a series of holes, which increase in size towards the patient end of the tube. Towards the machine end of the tube, the suction lumen is connected to a suction source by which suction is applied to the suction lumen to remove secretions that collect inside the tube.
