The main function of the closed thoracic drainage training model is to provide a highly simulated learning environment, so that students in medical colleges, clinical medical staff and medical training institutions can master the operation skills and procedures of closed thoracic drainage under safe and risk-free conditions. This model is not only an important tool for medical education and training, but also a key part of improving medical quality and ensuring patient safety.

Firstly, the closed thoracic drainage training model presents a thoracic environment very similar to the real human body through its fine anatomical structure simulation. The collarbone, sternum, ribs, intercostal space and other structures of the model are clear and recognizable, and the touch is real, so that the trainees can feel the tactile feedback similar to the real operation when performing thoracic puncture and drainage tube insertion and other operations. This highly simulated experience helps students mentally adapt and integrate into the surgical scene more quickly, reducing the tension and error rate in the actual operation.

Second, the training model has an advanced simulation system built in, which is able to simulate the accumulation of fluid or gas in the chest cavity and demonstrate the drainage effect in real time. When the drainage tube is placed correctly, the liquid level in the water-sealed bottle can be observed to fluctuate up and down with breathing (simulated liquid chest drainage) or the bubble can be continuously emitted (simulated pneumothorax drainage). This intuitive visual effect not only deepens the trainees' understanding of the principle of closed thoracic drainage, but also improves the accuracy of their evaluation of the drainage effect.

In addition, the closed thoracic drainage training model also has error warning function. When students make mistakes such as wrong puncture site or improper insertion depth of drainage tube during operation, the model will immediately issue voice or visual prompts to help students find and correct errors in time. This instant feedback mechanism helps students accumulate experience, improve operational skills and gradually form correct operational habits during the training process.

Finally, the application of closed thoracic drainage training model also promotes the innovation and development of medical education. Through the introduction of this high-tech teaching tool, medical colleges and medical institutions can provide students with more abundant and diversified learning resources and practical opportunities, so that they can participate and think more actively in the learning process. At the same time, this teaching mode also helps to cultivate students' innovative thinking and practical ability, laying a solid foundation for their future career.

To sum up, the main function of the closed thoracic drainage training model is to provide a highly simulated learning environment to help students master the operational skills and processes of closed thoracic drainage. At the same time, through its built-in simulation system and error prompt function, improve students' learning efficiency and operation skills; Finally, it will promote the innovation and development of medical education and contribute to cultivating more excellent medical talents.
