Historic Model of Childbirth

Teaching model shows stage 1 of labour.


Labour Stages Changes Time Roles
Stage 1 Dilatation 7 to 12 hours
longer for first child
Uterine contractions 10 minutes apart, function to dilate cervix fetal membranes rupture releasing amnion.
Stage 2 Expulsion 20 to 50 minutes Uterine contractions 2 to 3 minutes apart, function to push fetus through cervix and vagina.
Stage 3 Placental 15 minutes Uterine contractions following child delivery expel placenta. Haematoma separates placenta from uterine wall, separation occurs at spongy layer of decidua basalis.
Stage 4 Recovery 2+ hours Uterine contractions continue and myometrial contraction closes spiral arteries, also begins to reduce uterine volume.


About The Models - One of a series of models commissioned by Giuseppe Galletti (? - 1819) currently held in the Institute and Museum of the History of Science (Italy) Istituto e Museo di Storia della Scienza (IMSS). Giuseppe Galletti and others used terracotta and wax models that he had commissioned in Florence between 1770 and 1775 to train surgeons and midwives. Wax models are life-sized and the terracotta versions are reduced to a 1:3 scale.
