■ This model consists of six different models of cervical changes and birth canal relationships.■ This model includes the size of cervical dilation, the degree of change of the cervical canal, and the positional relationship between the fetal head and the sciatic spine.Stage 1: The cervical opening is not dilated, the cervical canal does not disappear, and the positional relationship between the fetal head and the ischium is -5.Stage 2: The cervix is dilated by 2 cm, the cervical canal disappears by 50%, and the relationship between the fetal head and the plane of the sciatic spine is -4.Three stages: The cervical opening is enlarged by 4 cm, the cervical canal disappears completely, and the positional relationship between the fetal head and the ischial spine is -3.Stage 4: The cervical opening is enlarged by 5 cm, the cervical canal completely disappears, and the positional relationship between the fetal head and the sciatic spine is 0.Stage 5: The cervical opening is enlarged by 7 cm, the cervical canal disappears completely, and the positional relationship between the fetal head and the ischial spine is +2.Stage 6: The cervical opening is enlarged by 10 cm, the cervical canal completely disappears, and the positional relationship between the fetal head and the sciatic spine is +5.
