The circulation system contains heart and blood vessels. It is profound that heart is able to pump blood to each organ of body everywhere via vessels. However, heart and vessels disease are main dead cause of citizen recently, human rush to realize the key of circulation and find out source of disease. Flow delivering control and pressure measurement are main methods of circulation inspection. According to the result of many reports between high blood pressure team and normal blood pressure team, many studies point out that high blood pressure causing disease of artery hardening is more dramatically than normal blood pressure is. Therefore it is necessary to control blood pressure not too high which may prevent artery hardening. There is normal blood pressure under fixed flow delivering in blood vessels; Different pressure will be measured under different flow delivering in vessels. It is outstanding to discuss the flow changing of aortic and abdomen artery under blood pressure changing in bio-medical area. The main purpose of this study is to simulate and measure pressure after flow delivering to aorta and carotid. This study is to design a simple 3-dimension physical model for aortic pressure, blood flow and pressure distribution status after heart contraction and blood flow delivering to aorta and abdomen artery. This research utilize self-design model of the Arch of Aorta combining a sensor, as well as a water pump to substitute the heart pumping task. By simulation of various input pressure of aorta, flow pressure and distribution of output abdomen artery and aorta are measured. The result examination data is collected and read by PC to accomplish analysis and exploration. The result of this research may help to predict occurrence of aortic disease and make contribution in medical area.
