| 摘 要： | 介绍了应用工程流体力学（EFD）软件对体外循环中夹管钳部分阻断静脉回流管道的流场进行仿真研究，并用美蓝作为标记物对部分阻断的管道进行流场再现，采用计算机模拟流场及美蓝显示流场两种方法来研究夹管钳部分阻断引起血液流动性能的变化，发现在目前使用方法上尚存在着一些缺点，探讨了有可能发生的不良后果。

| Abstract: | Using engineering fluid dynamics(EFD) softwares,we conducted a study on the simulation of flow field in vessel which was partially blocked by a clamp.The flow field of the partial block vessel was studied once more in real vessel when methylene blue as a marker was injected into the vessel.The change in the characteristics of blood flow was observed by way of computer imitation and methylene blue show.It was found that some defect might appear in the conventional method which partially blocked the vein. |
