ABSTRACT:
A transpharyngeal tube (10), especially for intubation anaesthesia, has a tube shaft (13) on which an inflatable primary cuff (18) for blocking the pharynx (19) and an inflatable secondary cuff (16) for blocking the esophagus (12) are disposed. At least one application channel (20) is formed on or in the tube shaft (13) which has an application opening (21), located below the primary cuff (18), for application of substances into the trachea (14). The secondary cuff (16) surrounds a tube tip (11) of the tube shaft (13) which seats in the entrance region of the esophagus (12) on an inner wall (15) thereof when the transpharyngeal tube (10) is inserted. This configuration of the transpharyngeal tube (10) facilitates a safe, reproduceable, and directed insertion into the esophagus (12) with which a safe and painless securing of the transpharyngeal tube (10) and controlled application of the application substance into the trachea (14) are guaranteed.
