摘　　要：目的建立一个更加贴近实际情况的具有广泛适用性的体外颈动脉血管分叉模型。方法利用超声多普勒技术在体测量颈动脉各部分的直径,借鉴音叉样颈动脉血管分叉模型的几何构造,对其从几何尺寸进行改良建立体外模型并利用粒子成像测速技术对模型内流场进行定量检测。结果结果显示模型内流场特点和分布与体内具有很好的相似性。结论我们建立的体外颈动脉血管分叉模型贴近实际,具有很好的代表性和实用性,可以为后续研究提供可靠的实验平台。Objective To construct a solid carotid artery bifurcation model with general applicability that simulates the real shape. Methods The diameter of the carotid artery was measured using ultrasonic cardiograph. A modified carotid artery model was constructed according to the tuning fork model geometry with the geometry size being rectified. The flow fields in the carotid artery model were detected by the particle imaging velocimetry technique. Results The characteristics of the distribution of the flow fields in the carotid artery model were similar to those in the human bodies. Conclusion The carotid artery we constructed well resembles the real shape and has good representativeness and practicability, which provides a reliable experimental platform for further research.
