This model is suitable for teaching for mechanism of normal labor in medical colleagues and nursing schools.
This model according to the mechanism of normal labor, can be used for showing the cardinal movements of engagement: descent –flection- internal rotation of the head – extension –restitution –external rotation of the head –internal rotation of the shoulders at accouchement.
Method of Showing:
Fitting together the rocker arm and shaft, turn round it clock –wise. After the fetus head (shows the position of L.O.A) has presented from the vaginal orifice. And the face has turned towards the left side, then stop the turning (the fetus still stay in mother’s body. Only the head is presented outside). After whole course is completed. Reverse the rocker arm until the fetus turns towards right side, then stop the reversion (if the head of fetus meets the resistance at the reversion, you can use left hand to push it inside slightly.)
CONSTRACTION: The mother’s body is made of fiber grass, the baby is made of PVC plastic, and the mechanical parts are made of metals.
