At present, laryngeal masks mainly include structures such as cuffs, laryngeal mask cannulas, indicator balloons, inflation tubes, machine end joints and inflation valves. In addition, since the patient's throat may secrete sputum and block the function during use, some laryngeal masks are equipped with a sputum suction function. For example: a modified double-chamber laryngeal mask disclosed in Chinese patent CN215690742U, a new airway esophageal double-pass laryngeal mask disclosed in Chinese patent CN2910241Y, etc. These laryngeal masks generally use double-chamber pipelines, and a sputum suction tube needs to be inserted into one of the lumens to absorb sputum.
