The pediatric bone puncture model is a highly realistic teaching device used for training children's bone marrow puncture and intraosseous infusion operations, which can help medical staff master standardized and safe puncture techniques.

Before operation, it is necessary to check whether the skeletal structure of the model, the puncture point marking and the liquid circulation system are in good condition to ensure that the simulated blood reflux and pressure feedback functions are normal.

During training, trainees must strictly adhere to the principle of aseptic operation, select puncture needles of appropriate specifications, and correctly fix the simulated limbs of the child patients. The puncture needle should be slowly advanced vertically or slightly inclined towards the bone surface. After touching the bone marrow cavity, the simulated fluid should flow back smoothly, indicating a successful puncture. During the puncture process, attention should be paid to the force and Angle to avoid excessive force causing damage to the model. After the operation is completed, bone infusion or drug injection practice should be carried out, and the needle should be removed in time, the puncture site and the surface of the model should be cleaned.

After the training is completed, the residual liquid should be drained, the model wiped and disinfected, and properly stored. Through standardized operation, the pediatric bone puncture model can effectively enhance the clinical skills, operational safety and ability to deal with emergencies of trainees.
