Abstract:
In this paper is presented the design of detection circuit and single chip acquisition circuit for heart sound, blood pressure and pulse wave. The multi-physiological signals from single chip are synthesized and processed by master computer. The master computer acquires, analyzes and displays the multi-signals by Software LabVIEW. The three physiological signals are fused to calculate the artery stiffness index by time relation of multi-physiological signals. The experiment shows that the circuit is reliable and effective so that it can be used for human vessel function evaluation.
