An endotracheal tube is provided with a catheter (5) that extends outwards and beyond a point that coincides with the beginning of the chamfered region of the tube (1) at its distal or inner end (3). In the region of the distal end of the catheter (5), the latter is provided with an inflatable ballonet (6). With this tube inserted until its distal end (3) is located inside the trachea, the catheter (5) enters the bronchus to be obstructed. The ballonet at the distal end of the catheter may then be inflated, obstructing that bronchus. According to the invention, the chamfered region of the distal end (3) of the tube (1) comprises a smooth tube wall without any lateral opening, which does not deviate from the axis of the tube, with respect to the wall of the tube (1) immediately prior to the chamfered region. |
