  • Non-tracheal ventilation tube
    Patent number: 7201168
    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.
