The larynx mask (1) is introduced via the mouth, ahead of the upper throat. An outwardly-projecting, integral tube (3) passes through the pharynx. A second tube (6) is included. This can be introduced through the first tube (3), into the airway. At one end, an inlet (14) is accessible from the exterior when introduced. The outlet (10) at the other end is located in a bronchial stem (8). The larynx mask (1) is introduced via the mouth, ahead of the upper throat. An outwardly-projecting, integral tube (3) passes through the pharynx. A second tube (6) is included. This can be introduced through the first tube (3), into the airway. At one end, an inlet (14) is accessible from the exterior when introduced. The outlet (10) at the other end is located in a bronchial stem (8). Close to the outlet opening an inflatable collar (9) hermetically-seals the annular space between the second tube and the inner wall of the bronchial stem. The first tube (3) is an airway for lung ventilation. The second (6) is a selective bronchial block, and at the same time forms a catheter tube for introduction of instruments. These remove blood and secretions from the airways, provide fiber-optic observation and/or ventilate the sealed-off lung. |
