The invention discloses a weak-
irritation triple-aspiration-prevention laryngeal
mask which can be put into the
gastrointestinal tract through the
nose. The weak-
irritation triple-aspiration-prevention laryngeal
mask comprises a laryngeal
mask body, a laryngeal mask bag, a
bite block, an air duct, an air duct interface, an air duct opening, a suction tube, a suction tube opening, a tongue central fovea, a uvula fovea and a
catheter groove, wherein the
bite block is arranged above the laryngeal mask body, the laryngeal mask bag is arranged under the laryngeal mask body, the air duct interface is formed above the
bite block, the back face of the upper-middle section of the laryngeal mask body is provided with the uvula fovea, the uvula fovea naturally extends along the back face of the laryngeal mask bag to form the
catheter groove, the tongue central fovea is formed in the center of the front face of the laryngeal mask body, the air duct opening is formed in the laryngeal mask bag, the suction tube opening is formed in the lateral rear side of the
tail end of the
catheter groove, and the suction tube penetrates into the upper portion of the laryngeal mask body and descends to the suction tube opening through the laryngeal mask body. The weak-
irritation triple-aspiration-prevention laryngeal mask is ingenious in structure and decreases the irritation of the laryngeal mask to the
pharynx oralis and facilitates
catheter indwelling and suction by being provided with the tongue central fovea, the uvula fovea and the catheter groove.
