The human secretory trachea model is a simulation teaching device used for respiratory system teaching and clinical skills training, mainly for demonstrating the physiological and pathological changes of the trachea and its secretions within the respiratory tract. The model is designed based on the real anatomical structure of the human body, fully displaying the distribution of the trachea, bronchi and part of the lung tissue. It can simulate the generation and discharge process of airway secretions, helping learners understand the mechanism of airway clearance.

In teaching applications, this model is widely used in medical colleges, nursing schools and respiratory therapy training courses to explain the structure and function of the respiratory system, the hazards of sputum retention, as well as nursing operations such as sputum aspiration and expectoration. Trainees can observe the flow of secretions in the airway through the model and master the key points of clinical operations such as airway humidification, postural drainage and mechanical sputum aspiration.

In addition, this model can also be used for health education to help the public understand the pathological processes of abnormal airway secretion in diseases such as chronic bronchitis, asthma, and COPD. Through intuitive demonstrations, the human secretory trachea model makes the abstract knowledge of respiratory physiology concrete, enhancing the teaching effect and the quality of clinical training.
