1. The similarity of anesthesia video laryngoscope and ordinary laryngoscope in structure allows doctors familiar with ordinary laryngoscope operation to quickly master the operation skills after training, and the learning curve is short;

2. A certain safe distance can be maintained between the operator and the patient to reduce contact with respiratory secretions, blood and vomit, and reduce cross infection;

3. The intra-oral structure can be clearly displayed on the screen, so that it can be seen clearly, the safe operation is more flexible, and image acquisition and video recording can be easily completed, which is convenient for teaching and scientific research;

4. The tracheal intubation time becomes shorter, the success rate is higher, and the esophageal intubation rate is lower;

5. Significantly improve the glottis exposure classification. Nearly 99% of patients have glottis exposure classification that can reach grade Ⅰ ~ Ⅱ (Cormack-Lehane classification), and can reduce the glottis exposure classification by at least 1 grade

6. The position of the ordinary laryngoscope during tracheal intubation is the olfactory level of the three axes of the mouth, pharynx and larynx in order to better expose the glottis. At the same time, various methods are often needed to improve the exposure. Move forward without the need for three axes and one line, and the operation range of the head and neck is small, suitable for cases of cervical spine injury;

7. The operation force is lighter, the damage is smaller, and the hemodynamics becomes more stable. Compared with ordinary laryngoscopes, video laryngoscopes can better perform tracheal and gastric intubation, reduce irritation of the throat, reduce adverse reactions, improve the ability of emergency pretreatment, and make anesthesiology and emergency medicine enter a new era.

8. The HugeMed anesthesia video laryngoscope in the visual laryngoscope adopts advanced scientific technology. Compared with similar products, it has a full-view high-resolution display with a 2 million pixel camera. It is clear to see and safe operation is more flexible; repeated use of anesthesia The video laryngoscope can obtain anti-fog function without preheating; the body is light, the operation is simple, easy to master, safe and efficient, and it can get a good glottic exposure, and at the same time reduce the chance of damage to the larynx tissue caused by intubation operation;
