The invention relates to an endotracheal or tracheotomy tube with a central lumen (2) for supplying and carrying off respiratory air. The tube comprises the following: an inflatable sealing cuff (3) which surrounds the tube (1); a pipe for supplying compressed air to the cuff (3); an aspiration duct (6) situated above or below the cuff (3) and ending outside the tube (1); and a supply pipe (7), which is also above the cuff (3) and ends outside the tube (1). The invention aims to create an endotracheal or tracheotomy tube which ensures safe tracheal aspiration, i.e. with which even viscous mucus or larger mucus lumps, which might have accumulated above the sealing cuff in a patient's trachea, can be reliably aspirated. To this end, the wall (9) of the tube (1) has a thickened hollow section (11) along a sector of its periphery, whose inner hollow space forms the aspiration duct. |
