Abstract
This invention provides an oral apparatus and method capable of alleviating or curing snore and obstructive sleep apnea by applying a negative pressure through a mini oral interface to the oral cavity. The mini oral interface creates a secure connection to mouth and prevents disengaging from patient's mouth during sleeping. The negative pressure pulls the tongue toward upper palate and also pulls the soft palate forward as well. By moving the tongue and the soft tissue in a forward direction, the patency of the upper airway near the pharynx is maintained to prevent sleep-disordered breathing. The negative pressure will pull the lips inward to close the mouth preventing air from entering the oral cavity from atmosphere. The negative pressure will also pull the soft palate into contact with the rear surface of the tongue to create a seal that prevents the air from entering the oral cavity through the nasal airway.
