Problems solved by technology

[0002] Due to lifestyle, work pressure and other reasons, the incidence of sub-health in the current society remains high, but it is very difficult to actually check and treat sub-health
Due to the complex symptoms, the evaluation methods are subjective and difficult to unify
People in a sub-health state cannot detect any organic lesions, functional changes or metabolic abnormalities, so they cannot be effectively diagnosed based on conventional medical methods and methods, so they cannot be treated or the treatment is not targeted

Embodiment Construction

[0021] The present invention adopts the photoplethysmography detection method, and the specific implementation method is: the light source placed on the finger or the side of the specific pulse wave collection part emits light of a specific wavelength, because the light intensity absorbed by non-pulsating tissues such as skin, muscle, and soft tissue does not change with time. Change, and the blood volume in the artery fluctuates periodically with the diastole and contraction of the heart, so that the light intensity it absorbs changes synchronously with the heartbeat. At this time, the light intensity detected by the photosensitive receiver is also a fluctuating signal, such as figure 1 shown. Since the movement of the human body will cause motion interference, the detected fluctuating signal will have baseline drift, accompanied by power frequency and high frequency interference, and a filter needs to be designed to remove it. Since the energy of the pulse wave is mainly dis...

Abstract

The invention relates to a human health evaluation method based on the harmonic waves of pulse waves. The method is characterized in that the photoplethysmography is used to measure the human pulse waves, single pulse wave segmentation is performed, a statistical method is used to perform eigenvalue extraction and sorting on the harmonic waves of the continuous single pulse wave, the phase space is built and a probability density function is calculated on the basis of the eigenvalue extraction and sorting, and the heath conditions of the internal organ functions of a to-be-evaluated person canbe evaluated according to the logarithmic normal distribution of the probability density of each harmonic wave.

Description

technical field [0001] The invention relates to a method for evaluating the health state of a human body, in particular to a mathematical method for establishing the relationship between pulse wave harmonics and the health state of meridians and viscera of the human body. Background technique [0002] Due to lifestyle, work pressure and other reasons, the incidence of sub-health in the current society remains high. However, it is very difficult to actually check and treat sub-health. Because of its complex symptoms, the assessment methods are subjective and difficult to unify. People in a sub-health state cannot detect any organic lesions, functional changes or metabolic abnormalities, so they cannot be diagnosed effectively based on conventional medical means and methods, and thus cannot be treated or the treatment is not targeted. [0003] From the point of view of human circulation, pulse wave is a quasi-periodic signal, which is triggered by the periodic beating of the ...
