摘要：
An oral device for improving airway patency comprises a tongue constraint and a negative pressure source. The tongue constraint engages the patients tongue to maintain a clear region below the palate in an oral cavity and allow an anterior portion of the tongue to rise. By applying a negative pressure in the clear region, an airway behind the soft palate or tongue of the patient can be maintained. The tongue constraint is usually connected to an anchor. The anchor may be held between the patients teeth or may engage the inferior surface of the palate. Another oral device for improving airway patency comprises a lateral tongue structure and a negative pressure source.
