Abstract An emergency airway tube for use in resuscitation of non-breathing patients by inserting the tube through the mouth until it randomly lodges either in the trachea or the esophagus. Only one insertion is needed. The tube is designed to ventilate the lungs regardless of which passageway it is lodged in. The tube has three tubes--the outer tube, an inner tube, which runs along and within the bore of the outer tube, and an air passageway for inflating an inflatable cuff located at the distal end of the outer tube which enters the trachea or esophagus. The end of the inner tube has a pneumatic seal for forming an airtight fit within and adjacent the distal end of the outer tube. The outer tube has a cluster of side air ports in its wall located generally midway between the ends of the tube. If the tip of the tube engages the trachea on insertion, the cuff is inflated and the inner tube will be the air passageway to ventilate the patient. If the tip of the tube engages the esophagus, the cuff will seal off the stomach. The outer tube will be the air passageway to ventilate the lungs by way of the side air ports in the outer tube's wall. A face mask is placed over the face of the patient to stop air leakage while the patient is being ventilated via the air ports.
A flexible emergency airway device for insertion through the mouth and randomly lodging either in the trachea or esophagus for resuscitating a patient, which comprises: an outer tube having a distal end and a proximal end and having at least one air port in the wall of said outer tube located intermediate the distal and proximal ends of said outer tube, said distal end of said outer tube being angularly cut and having a side port in the wall of said outer tube opposite from said angular cut; inner tube means for providing an airway through the mouth of a patient, placed longitudinally along and within the bore of said outer tube and terminating adjacent the distal end of said outer tube; interior sealing means for forming an airtight seal between the exterior wall of said inner tube means and interior wall of said outer tube and placed between said air port and the distal end of said inner tube means; exterior sealing means for forming an effective seal with the walls of the trachea or esophagus depending upon which passage said outer tube is lodged in, and attached adjacent said distal end and encircling said outer tube; a pilot balloon connected to said exterior sealing means by a passageway for indicating the amount of pressure in said exterior sealing means, and providing a means for inflating and deflating said exterior sealing means.
