Utilizing the fact that hemoglobin in blood absorbs light,
The blood flow state of the fingertip is detected by the light transmittance. Reference numeral 2 denotes a signal processing device, which is a signal processing device that amplifies the output waveform of the pulse wave sensor 1, performs secondary differentiation, and converts the digital signal. Reference numeral 3 is a personal computer for calculating and indexing digital output data of the signal processing device 2, and 4 is an image display device connected to the personal computer 3. FIG. 2 shows an example of the image display of the image display device 4. The measurement waveform 5 of the acceleration pulse wave is displayed on the screen, and at the same time, the health degree is shown as a bar graph based on the index value calculated from this measurement waveform. This is an example displayed in 6. The image display device 4 is not limited to the bar graph 6 and may be displayed in a pie chart or the like. In short, the image display device 4 is displayed in a graphic form.
