Artificial beating blood vessel model for medical phantom

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. So, a drive waveform was created with a function generator, and the motor was driven via a current drive device to generate blood flow by artificial beating. Previously, blood was simulated with water for the purpose of building the entire system, but this time we will increase the viscosity of the liquid that simulates blood flow. This takes into account the effects of blood on the blood vessels, blood flow, and pulsation to determine the effects on the human body. A liquid that has a viscosity close to that of blood has a slower response and a smaller amount of pressure change than water, so it is necessary to take into account the viscosity of the liquid. In order to construct a cardiovascular model with realistic pulsations, it will be required to generate pulsations with viscosity added in the future.
