The intubation must be gentle, the size of the tube is chosen to be such that it can easily pass through the glottic fissure, too thick or violent insertion can cause damage to the larynx and trachea, and too thin can be detrimental to breathing. After the body of a patient is anoxic, irreparable damage can be caused, particularly to the brain of the patient. When the first aid is carried out, the intubation is required to be carried out as fast as possible, and time is won for the patient. There is also a need to conditionally address the various conditions that occur in various patients and to increase the probability of successful intubation. But present visual first aid laryngoscope system not only need accomplish just can the oxygen suppliment after the intubate, has delayed the time of oxygen suppliment, and the function is still more single, nevertheless meets the internal steam condensation of patient on the laryngoscope surface, can not carry out the defogging, influences intubate efficiency and success rate. And if foreign matter exists in the throat part of the patient, the intubation is required to be stopped, the intubation can be continued after the foreign matter is cleaned by other means, the oxygen supply time is seriously prolonged, and the life health of the patient is very unfavorable.
