【摘要】：人体血液模拟循环系统(MCS)的目标是重现心血管血流动力学的特性。Westerhof阻力器在MCS中担任层流液阻器的角色,用来模拟心血管系统的外周阻力。Westerhof阻力器的理论计算结果较实际的液阻值有较大的误差,如果将理论公式计算的液阻值当作实际的液阻值,那么精确度明显达不到设计目标和性能要求。为了减少阻力器液阻值理论计算结果与实际值之间的误差,本文提供了一种有效的Westerhof阻力器计算阻值的校正方法,并且开发了仿真模拟软件。仿真软件可以较为准确地预测毛细管数量、总长度、液阻值,降低和简化了设计阻力器的难度和复杂度,使得Westerhof阻力器制作更为精准,为各种循环模拟系统的构建提供了支持。
[Abstract]:The aim of the human blood simulation circulatory system (MCSs) is to reproduce the characteristics of cardiovascular hemodynamics. Westerhof resistive devices act as laminar fluid dampers in MCS. The theoretical calculation results of the peripheral resistance .Westerhof resistor used to simulate the cardiovascular system have greater error than the actual liquid resistance value. If the theoretical formula is taken as the actual liquid resistance value, So the accuracy is obviously not up to the design objectives and performance requirements. In order to reduce the error between the theoretical calculation results and the actual values of the resistor, this paper provides an effective method for calibrating the resistance value of the Western of the resistor, and develops a simulation software. The simulation software can accurately predict the number, total length and liquid resistance of capillary, reduce and simplify the difficulty and complexity of designing the resistor, make the Westerhof resistor more accurate, and provide support for the construction of various cycle simulation systems.
