The Cervical Dilation and Birth Canal Relationship Model (JY/F20G) is a specialized medical education tool designed for obstetrics and gynecology training. This advanced model demonstrates the progressive changes of the cervix and birth canal during the first stage of labor, helping students and healthcare professionals gain hands-on experience with prenatal examination and labor assessment.

This training kit includes six interchangeable modules, each representing a different stage of cervical dilation, effacement, and fetal head position relative to the ischial spines:

• Stage 1: No cervical dilation, intact cervical canal, fetal head at -5 station.

• Stage 2: Cervix dilated to 2 cm, 50% effacement, fetal head at -4 station.

• Stage 3: Cervix dilated to 4 cm, fully effaced, fetal head at -3 station.

• Stage 4: Cervix dilated to 5 cm, fully effaced, fetal head at 0 station.

• Stage 5: Cervix dilated to 7 cm, fully effaced, fetal head at +2 station.

• Stage 6: Cervix fully dilated to 10 cm, fetal head at +5 station.

This realistic childbirth simulation model allows medical students, midwives, and nursing trainees to practice identifying cervical changes and fetal descent, improving both their diagnostic and clinical decision-making skills.

With its durable materials and high anatomical accuracy, the JY/F20G model is widely used in medical schools, nursing programs, and hospital training centers. It provides a safe and repeatable way to study obstetrics without risk to real patients, making it an essential teaching tool for maternal health education.
