Abstract

Objective This paper is to study the effect of psammotherapy on the hemodynamicsof the conical curved tube of the femoral artery in humans, and further reveal the mechanism of psammotherapy from the perspective of hemodynamics. Methods Based on CT images of the human aorta, a three-dimensional finite element model of the conical curved tube of the femoral artery was established, and the heart rate, the peak velocity and the inner diameter of the femoral artery measured in the experiment were used as initial conditions and boundary conditions for finite element numerical simulation, then the blood flow velocity, wall shear stress and Von Mises stress of curved blood vessels before and after psammotherapy were obtained and compared. Results The blood flow velocities of the conical curved femoral artery increased by 18%, 29%, 19% and 45% at t=0.15 min, 0.30 min, 0.45 min and 0.60 min after psammotherapy compared with before psammotherapy; the flow velocity of secondary reflux was significantly weakened, and the wall shear stress increased by 18%, 5%, 13%, and 14%, respectively; Von-Mises stress increased by 189%, 115%, 84%, and 338%, respectively. Conclusion Research shows that psammotherapy can improve the fluidity of the femoral artery blood and increase the wall shear stress, which has a corresponding improvement effect on the prevention of the deposition of substances in the arteries; the phenomenon of secondary reflux velocity after psammotherapy is significantly reduced to avoid the deposition of substances in the blood, and it has a certain clinically positive effect on preventing the formation of atherosclerosis, but after psammotherapy , the Von-Mises equivalent stress increases and the increase is also relatively large, indicating that psammotherapy has a potential risk of vascular rupture.
