Abstract
An emergency resuscitation endoesophageal airway comprises an arch-shaped respiration tube closed at a distal end but opened at a proximal end; a first inflatable balloon of a rubber-like elastic material attached to the respiration tube at a position close to the distal end thereof for closing an esophagus of a patient; a second inflatable balloon of a flexible synthetic resin attached to the respiration tube at a position spaced from the proximal end thereof for closing a pharynx of the patient; and first and second inflating tubes for inflating the first and second inflatable balloons. The respiration tube is provided with air holes between the first and second inflatable balloons but rather near the second inflatable balloon, and the second inflatable balloon is so designed as to expand in both longitudinal and radial directions to an extent much greater than the first inflatable balloon.
