Title:
LIVING BODY ABNORMALITY DETECTION DEVICE, LIVING BODY ABNORMALITY DETECTION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/187307
Kind Code:
A1
Abstract:
The present invention addresses the problem of accurately detecting an abnormality of a living body. This living body abnormality detection device includes: a signal acquisition unit for acquiring a first signal including a heart rate frequency component; a filter unit for generating a second signal by attenuating frequency components higher than the heart rate frequency component, and frequency components lower than the heart rate frequency component, on the basis of the first signal; a frequency analysis unit for indicating an analysis result of analyzing a frequency component of the second signal, on the basis of the second signal; an energy ratio calculation unit for calculating, on the basis of the analysis result, an energy ratio representing the ratio of frequency component energy of each frequency band to the entire energy of the second signal; a variance value calculation unit for calculating, on the basis of the analysis result, a variance value of the frequency component energy of each frequency band; and a detection unit for detecting at least abnormality or normality of the living body, on the basis of one of the energy ratio and the variance value, or both of the energy ratio and the variance value.
