Abstract
In this paper, an artificial beating blood vessel model was constructed in order to reproduce the cardiovascular system with beating and to be embedded it in a medical phantom. The torque generated by the motor is proportional to the driving current, so the current was controlled to generate artificial beating blood flow. The constructed vascular model exhibited a first-order lag system in pulse pressure response corresponding to a step-like input current. Based on this result, a drive waveform that combined with function waveforms was created by a function generator, and the motor was driven through a current driver to generate blood flow due to artificial beating. The pulse response was obtained as a pressure change that occurs according to the flow of blood flow due to the generated artificial beating. The completed artificial beating vascular model showed the characteristics of the first-order lag system with the time constant 1.3s.
