Abstract: A laryngeal mask airway includes: a guide tube that has one proximal end portion inserted into the larynx inside the trachea and the other distal end portion exposed to the outside of the trachea, guides the insertion of a flexible bronchoscope and an endotracheal tube inserted into the trachea, and is divided into left and right sides; a mask that is integrally connected to the one proximal end portion of the guide tube, prevents fluid and air from flowing into the larynx inside the trachea from the outside, and is divided into the left and right sides; a handle portion that is provided on the other side of the guide tube and protrudes to both sides of the guide tube to correspond to each other; and a coupling member that couples the guide tube and mask, which are divided into the left and right sides, to each other.
