The classic tracheal intubation training model is an important and commonly used device in medical teaching and first aid training, which is used to help trainees master the key first aid skill of tracheal intubation. The following points should be noted during use:

First of all, before operation, it is necessary to check whether the model structure is complete and whether the airway, oral cavity and visual larynx are unobstructed to ensure the smooth training.

Secondly, during practice, trainees should strictly follow clinical norms, move gently, and avoid damaging the model's teeth, larynx or tracheal components due to excessive force. When intubating, pay attention to the position of the head, correctly expose the glottis, and ensure that the catheter enters the trachea rather than the esophagus. Thirdly, when using lubricants or simulation solutions, it is necessary to avoid causing corrosion or residue to the model material to prevent affecting its lifespan. After the operation is completed, the model should be cleaned thoroughly, especially the airway and oral area, and properly stored.

Finally, during the training process, reflection should be conducted in combination with the monitoring or feedback system to summarize the shortcomings in the operation. By adhering to these precautions, the service life of the model can be prolonged, and at the same time, it can ensure that trainees can effectively improve their tracheal intubation skills in a safe and standardized environment.
