                                       Features：The arc-shaped structure of the distal end of the double-lumen
                                       bronchial tube has a guiding effect and is easy to locate. Double-lumen
                                       bronchial intubation adjusts the ventilation of single and double lungs through
                                       balloon inflation, which is simple and flexible. The double-balloon structure of
                                       the double-lumen bronchial intubation is well fixed, not easy to shift, and has
                                       high safety; Double-lumen bronchial intubation adopts high-capacity,
                                       low-pressure cuff, which has little damage to airway compression;
                                       The double-lumen bronchial intubation tube has a highly compliant and
                                       highly elastic air bag. When it is deflated, the air bag closes and completely
                                       adheres to the wall of the intubation tube, so that the tube can be extubated smoothly.
