Patent ID: 8857436

Claim:
An intermittent low-pressure orotracheal intubation device adapted for ventilating a patient comprising: (a) an endotracheal tube having a proximal end with an opening and a distal end with an opening, said distal end adapted to project into the trachea and said proximal end adapted to project from the oral cavity; (b) an inflatable balloon coupled to the tube near the distal end of said tube, said inflatable balloon surrounding a portion of said tube; (c) a one-way valve located inside the portion of the tube surrounded by said inflatable balloon; (d) a first port in said tube, proximal to said one-way valve, in fluid communication with said inflatable balloon; (e) a second port in said tube, distal to said one-way valve, in fluid communication with said inflatable balloon; wherein during inspiration air is forced into said tube from the proximal end, said one-way valve is closed forcing the air to exit said first port and distend said balloon, the air then exits the distended balloon via said second port; wherein the distention of said balloon is adapted to occlude the trachea to prevent air from escaping up the trachea during inspiration; and wherein during expiration said one-way valve is open to allow air to flow through the tube in order to substantially eliminate pressure by the balloon against the trachea.
