The advanced sputum aspiration practice model is mainly applied in nursing colleges, medical colleges and clinical training in hospitals, used to teach trainees the standard operation procedures and safety points of sputum aspiration techniques.

This model features a realistic structure of the human upper respiratory tract and can be used for sputum aspiration training in the oral cavity, nasal cavity and trachea, simulating sputum distribution and obstruction scenarios, allowing students to practice operations in a realistic environment. Through model training, trainees can become familiar with key steps such as the insertion depth of the suction tube, negative pressure control, aseptic operation, and patient position adjustment, which helps to avoid airway injury or hypoxia risks caused by clinical misoperation.

Teachers can also conduct situational teaching in combination with clinical cases to enhance trainees' emergency handling and communication skills. The application of this model not only enhances students' practical ability and clinical thinking, but also provides a safe and intuitive teaching platform for the pre-job training and continuing education of new nurses in hospitals.
