The thoracic (back) puncture training model is a simulation teaching device specially designed for teaching and clinical skills training. It simulates the anatomical structure of a real patient's back to help trainees master the key points of puncture operations in cases such as pleural effusion and pneumothorax. The surface of the model is made of simulated skin material and features touchable marks such as rib Spaces and shoulder blades, allowing learners to train the needle insertion Angle and palpation positioning in an environment "close to clinical practice".

This model is equipped with replaceable or drainage simulation thoracic cavities inside, supporting the simulation of different types of liquids. This enables trainees to experience real fluid aspiration feedback and enhance their ability to judge changes in puncture depth and resistance. Its structural design can be reused repeatedly and is suitable for medical school teaching, hospital skills training, assessment and simulation exercises. It helps standardize operation procedures, reduce the risk of clinical complications, and significantly improve the safety and success rate of medical staff in actual operations.
