METHOD OF NON-CONTACT MEASUREMENT OF BIOLOGICAL RHYTHMS ACCOMPANIED BY MECHANICAL MOVEMENTS OF HUMAN BODY SURFACE

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, in particular to instrumental functional diagnostics, and can be used for the non-contact measurement of biological rhythms, accompanied by mechanical movements of the surface of the human body. Person in the relaxed state holds a static posture. Microwave radiation from a stationary source perpendicular to the plane tangent to the investigated area is directed to the area of the human head. Take the microwave radiation reflected from the investigated region. Compare the parameters of the radiated and received signals, which carry information about the movement of the investigated area. Mechanogram of the investigated area is registered as a digital data file. Method of digital filtering of signals produces a separation of biological rhythms, accompanied by mechanical displacements of the investigated region with different frequencies. Registered mechanogram is divided into cardiac, respiratory and cranial rhythms. To divide the respiratory and cranial rhythms, the subject is given rhythmic signals, affecting one of the senses, such as sight, hearing, touch, with a significantly higher frequency than the frequency of the cranial rhythm of the subject. In accordance with the rhythmic signals, the person being examined synchronizes the respiratory rhythm.;EFFECT: method provides an increase in the accuracy of non-invasive non-invasive registration and measurement of the parameters of three biological rhythms – cranial, cardiac and respiratory.;8 cl, 3 dwg, 2 ex
