A Hydraulic Model of Arterial System for Study the Relationship Between Blood Distribution and Frequency Characteristics of Blood Pressure Waveform

Abstract

This paper was trying to find out a suitable hydraulic model for studying the frequency characteristics between blood pressure waveforms and systemic blood distribution. In the hydraulic model, the elastic tubes simulated the aorta and its major branches. The small balloons with different stiffness were used as organs. We used two kinds of tubes to test the hydraulic model and tried to find out suitable material to stimulate the aorta and its major branches. We also used different volume of balloons to stimulate the organs. The self-designed pump that could generate arbitrary pressure waves and pure sinusoidal waves was used to stimulate the heart. For each different output waveforms of the pump, we measured the flow into each balloon by ultrasonic transducer and the pressure at the same sites by strain gauge transducer. Summary of the experiments showed that the latex tube was suitable material than silicon tube.
