At present, the video laryngoscopes on the market have requirements on the opening of the patient. Some burn patients and difficult airway patients with broken jawbone cannot use the video laryngoscope for intubation, and can only use a rigid endoscope or a flexible endoscope. At present, the rigid endoscopes on the market require manual plasticization, which will delay the rescue time of patients. Moreover, the rigid endoscopes or soft endoscopes need to be sterilized and reused, which is cumbersome and has the risk of cross-infection due to incomplete disinfection, and the cost of using the flexible endoscopes is relatively high. High, the professional level of doctors is also relatively high, and our product is equipped with a disposable sheath, which can truly avoid cross-infection, and can adjust the angle of the front end of the tube core by pressing the handle, which can be accurately performed on a visual basis. Quick intubation, this product has low requirements on the patient's opening, and can also be easily intubated for special patients with partial glottis. It is a real tool to solve difficult airway intubation.
