The advanced sputum aspiration practice model is a highly realistic simulation device specially designed for respiratory care and critical care training, and is widely used in nursing education and clinical skills training. This model is strictly made in accordance with the anatomical structure of the respiratory tract of adults or infants, including the branches of the oral cavity, throat, trachea and bronchi. It can realistically simulate the accumulation of phlegm and respiratory tract obstruction, providing trainees with a real operation experience.

The operation guide first emphasizes aseptic operation. Before training, trainees should wear gloves and masks and disinfect their hands. They should also prepare suction tubes, suction devices and necessary disinfectants. During the sputum aspiration process, the breathing condition of the simulated patient should be evaluated first. The airway should be gently opened to avoid causing damage to the airway wall. When operating, the sputum suction tube should be slowly inserted along the direction of the trachea, maintaining an appropriate negative pressure and slowly rotating while suctioning until the sputum is smoothly sucked out. After the sputum aspiration is completed, the sputum aspiration tube and the model mouth should be cleaned immediately to keep the equipment clean for the next training.

This model is usually equipped with a replaceable sputum storage system and an adjustable resistance device, which can simulate sputum of different viscosities and volumes, enhancing the authenticity of the operation. Through repeated practice, trainees can master the standard techniques, timing selection and operational force of sputum aspiration, thereby enhancing clinical safety and operational efficiency. The advanced sputum aspiration practice model is not only an important tool for skills training, but also provides a reliable guarantee for improving the respiratory tract management ability and emergency response level of nursing staff.
