Female pelvis and two fetal heads, designed to demonstrate the process of childbirth.
Two interchangeable heads — one full-term, the other preterm — are mounted on a flexible rod, allowing them to pass through the pelvic outlet in various positions.
Both fetal heads contain skulls with palpable cranial sutures and anterior and posterior fontanelles.
The models can also be used to demonstrate childbirth using forceps or vacuum extraction.
