LIVING BODY CONDITION MEASURING APPARATUS

摘要

An apparatus for uninvasively evaluating hemodynamic parameters, particularly a sphygmographic analyzer for evaluating vessel compliance and flow resistance in the central and peripheral portions of the artery system separately. A microcomputer (4) detects the radial artery wavefrom of an object through a sphygmograph (1), and fetches a stroke output of the object from an output meter. Next, the value of each of the five elements that constitute an electric circuit simulating the artery system ranging from the central portion to the peripheral portion of the living body is adjusted on the basis of the stroke output so that when an electric signal corresponding to a pressure wave of the aortic origin of the object is applied to the electric circuit, its response waveform corresponds to the radial artery waveform, and the resulting value of each element is outputted as the hemodynamic parameter. Further, the pulse waveform, the maximum blood pressure value and the minimum blood pressure value at the aortic origin are calculated from the value of each element, and the calculation result is outputted to an output device (6).
