B. For who use
1. The models are suitable for the training in medical college, nursing school and clinic training institute.
2. They can be used for the training of nurse, intern student, etc
3. grass-root medical institute

C. Function and Guideline

Phase 1 :
The orifice of cervix has no expanding, and the cervical tunnels haven’ t disappearedat all. The positional relation between the head of fetus and the square of ischial spine is – 5

Phase 2 :
The orifice of cervix has expanded 2 cm bigger, and the cervical tunnelsdisappear 50% . The positional relation between the head of fetus and the square of ischial spine is -4

Phase 3 :
The orifice of cervix has expanded 4 cm bigger, and the cervical tunnelsdisappear 50% . The positional relation between the head of fetus and the square of ischial spine is -3

Phase 4 :
The orifice of cervix has expanded 5 cm bigger, and the cervical tunnelsdisappear 50% . The positional relation between the head of fetus and the square of ischial spine is 0

Phase 5 :
