摘要： Apparatus for use in artificial respiration and stomach evacuation comprising an elongated member and ventilation mask. The elongated member which is designed to be inserted into the esophagus and stomach has an expandable inflatable element which can be operated externally after insertion in order to close the esophagus to prevent inflation of the stomach or aspiration of the contents of the stomach into the respiratory system. The ventilation mask, which fits over the mouth and nose provides a seal against the patient''s face when it is held in place. A ventilation opening in the mask allows air or oxygen to be directed through the mouth into the lungs for artificial respiration. The apparatus preferably includes a tubular fluid passageway in the elongated member with evacuation openings beyond the inflatable element to allow the contents of the stomach to be aspirated through the passageway and externally of the mask. Fluid can also be introduced into the stomach through the passageway.
