The Advanced delivery mechanism demonstration series model is a set of highly realistic obstetric teaching equipment used for systematically demonstrating and teaching the entire delivery process. It is widely applied in medical colleges and universities, midwife training, and clinical advanced study teaching.

This series of models typically includes components such as simulated pelvises, fetal models, placentas, and umbilical cords, which can visually demonstrate key steps of the delivery mechanism such as fetal head connection, descent, rotation, and delivery, helping trainees understand the anatomical and dynamic changes during the first, second, and third stages of labor. The model adopts realistic structural proportions and soft materials, and can also simulate different fetal positions, fetal postures and abnormal delivery scenarios, such as occipital posterior position and shoulder dystocia, allowing trainees to practice midwifery operations in a controllable environment. Some advanced models are equipped with a transparent pelvic structure, which facilitates the observation of the dynamic changes of the fetus in the birth canal. At the same time, by integrating electronic or multimedia demonstration systems, synchronous explanations and step-by-step teaching can be carried out to enhance learning efficiency.

Through this series of models, trainees can combine theoretical knowledge with practical operation, become familiar with the mechanisms of normal and abnormal delivery, master delivery skills and emergency handling methods, reduce the tension and mistakes of clinical beginners in real delivery, and thereby effectively improve the professional level and safety of obstetric care and midwifery.
