Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to a tracheal intubation auxiliary device. BACKGROUND

[0002] In surgery or first aid, endotracheal intubation is a key operation to maintain the airway of a patient, but the process has significant clinical risks. The intubation operation itself is extremely risky, and the operation process is complex, and needs to rely on a laryngoscope or a fiber bronchoscope to assist in segmental spraying of surface anesthesia, which is cumbersome and requires a very high technical level of the operator. The complexity of the operation and the strong technical dependence directly lead to a prolonged operation time, and thus require a longer continuous oxygen supply time; and in the intubation process, interruption or insufficient oxygen supply significantly increases the risk of respiratory distress or even hypoxia of the patient. The difficulty of tracheal intubation varies greatly due to individual differences and the complexity of the patient's condition, and even experienced anesthesiologists cannot completely avoid operation failure. About 1 / 3 of anesthesia-related direct deaths are caused by intubation failure, and it is difficult to accurately identify all difficult airway conditions in advance in clinical practice.

[0003] In addition, there is a lack of effective real-time airway tracing and continuous oxygen supply support means in the existing surface anesthesia and intubation operation, which leads to deviation in finding the glottis path and no oxygen supplement, resulting in low fault tolerance and concentrated operation risk.
