Abstract: A laryngeal mask airway (LMA) for gastroscopy includes a laryngeal tube for gastroscopy. A drainage tube is fixedly installed on an outer surface of an upper end of the laryngeal tube for gastroscopy. A PC connector is fixedly installed at one end of the drainage tube. A ventilation hole is formed in an outer surface of an upper end of the drainage tube, and a suction hole is formed in an outer surface of a lower end of the laryngeal tube for gastroscopy. An inner cavity and an inflation tube hole are formed inside the laryngeal tube for gastroscopy. The inflation tube hole is disposed under the inner cavity and receives an inflation tube, and a single-cavity connector is fixedly installed at one end of the inflation tube. The LMA absorbs secretions from a patient's esophagus to minimize coughing during a gastroscopy, thereby reducing patient discomfort and pain.
