In one embodiment, the device includes a mouthpiece that is adapted to forni a sealed cavity within a human mouth, and a hollow elongate member having a first end that is coupled to the mouthpiece and that is in communication with the sealed cavity, and a second end that is adapted to be coupled to a negative pressure generator. In use, a negative pressure generator can be attached to the hollow elongate member to create a negative pressure in a human mouth in response to an obstructed airway, thereby removing the obstruction. In particular, this device is effettive to pull a patient's tongue and/or soft tissues of the upper airway up and away from the posterior pharyngeal wall to reopen the airway. |
