The suction device is made up of a U shaped body (5) whose arms contain horizontal cavities to be engaged and centered with the teeth (15), and a bulb shaped section, extending from the internal side of the U shaped body (5) and being attached to this latter by means of a narrow shaped neck, expanding to form a flat base which is adaptable to the tongue and a curved upper portion adaptable to the palate (10), being said bulb shaped section, both flexible and adaptable and having orifices (6) through which air may pass, which orifices communicate with one of the cavities in the U shaped part of the structure, to allow for the passage of the air in accordance with the suction cycles. The device permits the recovery of the tone of the jaw muscles and the soft palate and avoids and corrects the ogival palate, permitting as well as to increase ventilation space in the rear area of the nasal cavities. |
