Abstract
A non-tracheal ventilation tube includes a multi-lumen tube shaft having a proximal end and a distal end, a proximal cuff and a distal cuff. The multi-lumen tube shaft is separated into a ventilation channel extending from a proximal ventilation opening to a distal ventilation opening, a suction channel extending from a proximal suction opening to a distal suction opening, and an inflation channel. The proximal cuff is attached to the tube shaft and is connected to the inflation channel for inflation and deflation. The distal cuff is attached to the tube shaft on the distal side of the proximal cuff and is connected to the inflation channel for inflation and deflation. The proximal suction opening and the proximal ventilation opening are located on the proximal side of the proximal cuff. The distal suction opening is located on the distal side of the distal cuff. The distal ventilation opening is located between the proximal cuff and the distal cuff. The outside diameter of the tube shaft decreases between the proximal cuff and the distal cuff due to the ending of the ventilation channel.
