Patent ID: 7201168

Claim:
An non-tracheal ventilation tube comprising: a multi-lumen tube shaft having a proximal end and a distal end, said multi-lumen tube shaft being 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; a proximal cuff attached to said tube shaft and connected to said inflation channel for inflation and deflation; a distal cuff attached to said tube shaft on the distal side of said proximal cuff and connected to said inflation channel for inflation and deflation; said proximal suction opening and said proximal ventilation opening being located on the proximal side of said proximal cuff; said distal suction opening being located on the distal side of said distal cuff; said distal ventilation opening being located between said proximal cuff and said distal cuff; the outside diameter of said tube shaft decreasing between said proximal cuff and said distal cuff due to the ending of said ventilation channel.
