摘要

This paper deals with the frequency characteristics of blood pressure waveforms to systemic blood distribution in the context of developing a hydraulic model of the overall system. The elastic tubes simulated the aorta and its major branches. The small balloons with different stiffnesses were used as organs. The self-designed pump which generated arbitrary pressure waves and pure sinusoidal waves was used to simulate the heart. For each of the different output waveforms of the pump, we measured the flow into each balloon by ultrasonic transducer and the pressure at the same sites by strain gauge transducer. A summary of the experiments showed that the distribution of flow is affected by the frequency characteristics of the pressure waveforms. The flow patterns recorded near the entrances of the branches also suggested that each balloon has a specific relation to frequency. In this way, this paper provides a framework for future efforts in hydraulic model and animal model experiments for the systemic circulation.
