The Advanced Delivery Mechanism demonstration series model is a professional simulation device used in obstetrics and gynecology teaching and midwifery skills training, aiming to help learners intuitively understand the entire delivery process and key points of related operations.

This series of models typically includes simulated pelvises, fetal models and uterine appendages, capable of demonstrating the entire process of the delivery mechanism, including fetal head connection, descent, internal rotation, extension, repositioning and external rotation, and clearly showing the interrelationship between the fetus and the mother's pelvis during labor. The model adopts a transparent or semi-transparent design, making the fetal position, fetal direction and rotation process visible, which is convenient for teachers to explain and students to observe.

Through manual operation, learners can repeatedly practice different labor scenarios and master the changing patterns of each stage of fetal delivery. Some advanced models are also equipped with electronic monitoring or multimedia systems, which can synchronously record and display the operation process, enhancing the interactivity and intuitiveness of teaching.

This series of models not only helps students firmly master theoretical knowledge and operational skills, but also cultivates midwives' ability to analyze and deal with complex labor processes, which is of great significance for improving the quality of obstetric teaching and ensuring the safety of mothers and infants
