Investigation of vascular morphology prediction based on high dimensional pulse acquisition system and finite element...

In this paper, we propose a novel pulse acquisition system based on MEMS technology, where finger-end pressure and micro-sensor array applications are combined to achieve a high degree of integration of multi-channel information at the pulse acquisition end. A static stress analysis model for blood vessels based on the finite element method is proposed, which is used to investigate the effects of the modulus of elasticity of the vessel wall, and the inner diameter of the vessel on the outward pressure. The blood flow patterns of people with different blood pressures were simulated by varying the pressure intensity of the vessel wall. And the accuracy of the model was verified by collecting pulse waves of hypertensive patients by the designed pulse information acquisition system. This study is expected to enable non-invasive and low medical cost preliminary vascular lesion diagnosis through the detection of pulse.
