摘要
A novel nasogastric tube, that when properly inserted within a person, blocks the esophagus of the person to prevent gastric contents from being aspirated. The tube can be left in place during direct langroscopy and the device can include a preferably inflatable balloon for obstructing the person's esophagus. This balloon can be preferably provided on a slidable tube that allows for head movement/flexion without movement of the balloon placement. The tube can be a dual or single lumen device. With a duel lumen device, a first lumen can be connected to a suction tubing to suction gastric contents from the distal end of the tube, while the other lumen can open up above the cuff to allow for easier ventilation with a bag valve mask/BVM.
