The bone marrow puncture training model is an important teaching tool for medical students and clinical personnel to master bone marrow puncture techniques. Model structure simulation, including multiple layers of tissues such as skin, soft tissue, bone layer and bone marrow cavity, can simulate the puncture operation of adults or children. To ensure the training effect and equipment safety, the following matters should be noted during operation.

First of all, before operation, the appearance of the model and whether all its components are intact should be checked to ensure that there are no foreign objects or residual liquids in the bone marrow cavity. Before puncture, routine hand hygiene and aseptic operation should be carried out. Select an appropriate puncture site, such as the anterior superior iliac spine or the handle of the sternum, and insert the needle at the specified Angle and force to avoid excessive force that may cause damage to the model.

During the practice process, attention should be paid to the coordination of needle sensation experience and negative pressure suction, and the real operation steps should be simulated. After the puncture is completed, the needle should be removed promptly and the needle hole and surface should be cleaned with a special disinfectant to prevent material aging or contamination. The model should be properly stored in a dry and well-ventilated place, avoiding direct sunlight or heavy pressure. Strictly adhering to the operation norms not only prolongs the service life of the model but also helps cultivate trainees' standardized and safe clinical operation habits.
