ABSTRACT:
A pulse wave analysis device for analyzing the condition of a human body is disclosed. A cuff band is wrapped around the tip of the second finger of a subject's hand. When the operator depresses the beginning-of-measurement key, the finger tip is pressed at various pressures by means of an air pump and a pressure sensor. Pulse wave signals at different pressure values are automatically measured by an optical fingertip plethysmogram sensor. The signals are transmitted to a CPU through a BPF, an amplifier, and an ADC. The CPU performs FFT analyses on the signals and determines to which pattern from among the patterns stored in a ROM the pattern level of the pulse wave spectrum for a given pressure value is closest, and displays the result on a display unit as a test result indicating the viscoelasticity of the subject's peripheral circulation tissue.
