Plastic Model

Physical plastic model with hydraulic pump to simulate coronary arteries of a beating heart, data acquisition and control system in the background, power supply for the hydraulic beat-pump to the right. Observe the red plastic stenoses inserted in the plastic tubes and the diameter changes of connected plastic tubes.
The model operates in the water-filled plastic container.
