The infant bone marrow puncture model is a simulation teaching aid specifically designed for medical teaching and clinical skills training, mainly used to simulate the operation of infant bone marrow puncture. This model is designed based on the anatomical structure of infants and usually features realistic textures of skin, soft tissues and bony structures, allowing trainees to experience the real resistance of needle insertion and the feeling of entering the bone cavity during training.

During the usage process, trainees can become familiar with the commonly used sites for bone marrow puncture, such as the tibial plateau, and master the complete operation steps including disinfection, positioning, fixation, needle insertion, and bone marrow extraction. This model not only helps improve the operator's technical proficiency and sense of touch, but also enables repeated practice in a risk-free environment, reducing the error rate in clinical operations.

At the same time, it is also of great significance for cultivating trainees' aseptic concepts and emergency operation capabilities. The application of the infant bone marrow puncture model provides a scientific, intuitive and safe training platform for medical teaching, enhancing the standardization and practicality of clinical teaching.
