The Advanced delivery mechanism demonstration series model is a highly realistic teaching device used for obstetric science teaching and midwifery skills training. It can visually display various delivery mechanisms and fetal exposure changes of the fetus in the mother's birth canal. This model typically includes the maternal pelvis, fetal model and related auxiliary structures, and can demonstrate various delivery postures such as occipital anterior position, occipital posterior position and breecular position, clearly showing key links such as flexion, internal rotation, extension and repositioning of the fetal head. Through intuitive mechanical demonstrations, trainees can better understand the physiological process of childbirth and the changes during labor.

In teaching and practical training, the advanced delivery mechanism demonstration series models are widely used in midwife training, nursing colleges and clinical teaching to explain the occurrence mechanisms of normal delivery and dystocia. Trainees can conduct operation practice on the model to master midwifery techniques, key points of delivery, and methods for identifying and handling abnormal deliveries. This model not only enhances the interactivity and visibility of teaching, but also helps trainees organically combine theoretical knowledge with practical skills, providing strong support for cultivating midwifery professionals with clinical judgment and emergency response capabilities.
