摘要:
目的：通过建立下肢静脉泵对下肢作用的双向流固耦合仿真模型，对不同的加压和释压模式进行研究，获取下肢静脉血液的流速分布和产生的功效，为合理设置下肢静脉泵工作参数提供指导。方法：以24岁健康男性右小腿为对象，采用3D扫描仪得到其外轮廓；采用彩色多普勒超声仪得到其大隐静脉、小隐静脉和胫后静脉的内径、血管壁厚与血液静息流速数据。利用SolidWorks软件构建小腿三维实体模型；使用Ansys Workbench软件构建下肢静脉泵对下肢作用的双向流固耦合仿真模型。结果：探讨下肢静脉泵的加压和释压模式，得到下肢静脉血液的流速分布情况。结论：基于下肢静脉泵对下肢作用的双向流固耦合模型，优化了下肢静脉泵的加压和释压模式，可以增强治疗效果，提高功效和安全性。
Abstract:
Abstract: Objective To establish a bidirectional fluid-structure interaction model of the venaflow acting on the lower limb for investigating its pressure and depressure modes, and analyzing the velocity distribution of venous flow in the lower limb and therapeutic efficacy, thereby providing guidance for the resonable setting of working parameters of the Veneflow. Methods The right lower limb of a 24-year-old healthy man was taken as the object. The outer contour was obtained with a 3D scanner, and the inner diameters, wall thicknesses and resting blood flow velocities of the great saphenous vein, small saphenous vein and posterior tibial vein were measured with color Doppler ultrasonography. A 3D solid model of the lower limb was built with SolidWorks, and a bidirectional fluid-structure interaction model of the venaflow acting on the lower limb was constructed with Ansys Workbench. Results The velocity distributions of venous flow in the lower limb in the pressure and depressure modes of the venaflow were obtained. Conclusion Through the analysis with the bidirectional fluid-structure interaction model of the venaflow acting on the lower limb, the pressure and depressure modes of the venaflow are optimized, which can enhance the therapeutic efficacy and improve the safety.
