when the multiple bulges of the visual device 1 smoothly and completely pass through the laryngeal mask channel:

when the visual device 1 is used on the large-length laryngeal mask, the ring piece 13 can be inserted into the reserved visual cavity 4 of the large-length laryngeal mask due to the compatibility of the visual device with the small-length laryngeal mask;
