Neontal simulator for measuring growth and development indicators

■  The above three newborn simulators (all male) have heights of 52CM, 50CM, and 47CM, respectively; The head circumference is 42CM, 34CM, and 31CM respectively; The weight is 3KG, 2KG, and 1.7KG respectively.
Body length measurement: The knee and ankle joints of the newborn simulation simulator can move freely, and the legs are M-shaped in natural state. When measuring the newborn's body length, the operator can straighten the newborn's knee joints and push the newborn's feet straight to form a 90 degree angle with the legs.
■  The simulation simulator has an internal circuit. If the operator fails to hold the neck in time during the measurement of the newborn, causing the newborn's head to tilt back significantly, the first red light will light up. When the operator behaves rudely, causing the newborn to be thrown, the second red light comes on.
