The significance of the infant tracheal intubation training model lies in providing a safe and controllable practical training platform for the respiratory tract management of newborns and infants. 

This model highly simulates the anatomical structure of the airway and can truly simulate the resistance, touch sensation and position of the tube during the intubation process, enabling learners to master the correct techniques, angles and depths of tracheal intubation. Through repeated practice, trainees can increase the success rate of operations and reduce the risk of airway injury, misinsertion or hypoxia caused by unskilled techniques.

The model can also be used to train the fixation, sputum aspiration and complication management after tracheal intubation, enhancing the risk identification and emergency response capabilities of nursing staff. The training model of infant tracheal intubation is widely applied in neonatal and pediatric nursing teaching, first aid training and skills assessment. It is of great significance for improving clinical operation level, ensuring the safety of infant respiratory tract and enhancing first aid ability.
