The development process of the training model for neonatal tracheal intubation has undergone continuous evolution from simple static models to highly realistic and multi-functional intelligent equipment.

Early training models mostly used plastic or rubber materials, with simple structures, and were only used to demonstrate the basic path of tracheal intubation. They lacked realistic anatomical details and feedback mechanisms, resulting in limited training effects. With the promotion of neonatal critical care and resuscitation techniques, medical education has put forward higher requirements for the fidelity and functionality of models. Mid-term products have begun to introduce designs that conform to the structural proportions of the neonatal oral cavity, throat and trachea, and add soft materials to simulate the touch of mucous membranes. The visualization degree of the airway has significantly improved, and trainees can more intuitively grasp the depth and Angle of intubation. Entering the modern stage, the model integrates high-resolution video assistance, electronic sensors and intelligent assessment systems. It can not only monitor the intubation time, force and position in real time, but also simulate various clinical scenarios such as airway obstruction and laryngeal spasm, allowing trainees to train in a more realistic neonatal respiratory management environment.

In addition, some high-end models can be linked with the resuscitation simulation system to achieve a complete teaching of the first aid process from airway management to cardiopulmonary resuscitation. This development process reflects the transformation of medical education from simple skill demonstration to an immersive, quantifiable and assessable comprehensive training model, providing a solid support for improving the level of neonatal emergency rescue.
