Abstract: A laryngeal tube with a self-sealing valve, a pilot balloon, a cuff inflation line, a suction port, and a radiopaque cover. The laryngeal tube further includes a proximal cuff for securing a pharyngal area of a patient and a distal cuff for preventing oxygen escape into a stomach of the patient. The laryngeal tube further includes a suction lumen configured to reduce a risk of aspiration in a trachea of the patient and a pharyngal lumen configured to provide ventilation capacities. The self-sealing valve surrounds a periphery of the cuff inflation line. The suction port, the cuff inflation line, the self-sealing valve, and the pilot balloon all extend through an interior of the radiopaque cover, which connects the pharyngal lumen to the proximal cuff.
