[0003] At present, the method of airway ultrasonic examination is as follows: first, a layer of ultrasonic coupling agent is manually applied along the airway extension direction of the examinee to prevent the inaccuracy of the examination result due to the air entering the probe-skin gap during ultrasonic examination, then the convex array ultrasonic probe is manually operated to scan along the trachea extension direction, specifically, longitudinal section examination (sagittal plane) is performed on the total length of the airway, and transverse section examination (transverse section) is performed on multiple predetermined positions on the total length of the airway, finally, the ultrasonic coupling agent layer is wiped off.
