A phantom for medical training which simulats a human body is used for training of accurate treat. Blood vessels embedded in a phantom are made of tubes whose dynamic characteristics are similar to real blood vessels. But actually, blood vessels are also pulsing along with heart beat and bloodstream. Therefore a heart blood-vascular system with artificial pulses and embedding it in phantom for medical training are required. In this research, modeling of the blood vessel along with artificial pulses was executed. Motor torque of the pump is proportional to driving current, so artificial pulses can be generated by controlling the current. Response of the pulse pressure indicated a first order time lag to a step input. As a result, a bloodstream with pulses were generated by driving the motor with an arbitrary waveform composed of several function waveforms.
