Research on Pulse Wave Modeling Method Based on Equivalent Circuit of Two Elastic Chambers Model

The pulse wave contains a large amount of physiological and pathological information and has a wide range of applications in the field of medical health. This paper analogizes the two elastic chambers model with the circuit model, obtains the circuit model of the two elastic chambers model, derives the transfer function of the tail chamber pressure of the two elastic chambers model and the blood flow rate of the pump-in model, and thus obtains the Simulink pulse wave simulation model. The pulse wave waveform drawn by simulation is basically consistent with the waveform obtained by the pulse wave tester, which verifies the effectiveness of the simulation model. At the same time, the effect of simulation model parameters on the pulse wave waveform is studied, providing a method for obtaining simulation data for further study of the pulse wave waveform.
