The role of the advanced sputum aspiration practice model is to provide a realistic training platform for nursing staff and medical students, enabling them to master key skills in airway management.

Sputum aspiration is a common and important operation in clinical nursing. It can promptly remove respiratory secretions from patients, keep the airway unobstructed, and prevent asphyxia and pulmonary infection. This model is designed based on the real anatomical structures of the human trachea, oral cavity and nasal cavity, and can simulate various operation scenarios such as oral and nasal sputum aspiration, tracheal intubation sputum aspiration and artificial airway sputum aspiration.

Through practice, trainees can become familiar with the selection of sputum suction tubes, the insertion depth and the correct application of negative pressure, avoiding mucosal damage or hypoxia caused by improper operation. Meanwhile, the advanced model also features a realistic secretion simulation function and feedback system, which can assist the operator in judging the sputum suction effect and the patient's response.

Through repeated training, trainees can correct movement deviations, enhance clinical sensitivity and adaptability. Such models not only enhance the safety and scientific nature of practical training, but also lay a solid foundation for ensuring the respiratory safety of patients and the quality of care.
