This Video Laryngoscope is a visual intubation system composed of a blade, a handle, and an LCD display. Firstly the doctor inserts the laryngoscope into the throat, and then the Video Laryngoscope clearly displays the structure of the larynx and the glottis. Compared to traditional laryngoscopes, it is more convenient to operate and observation accuracy is higher. At the same time, different types of blades are available for use with different groups of patients, including infants, children, adults, and obese patients.
