METHOD OF WAVELET-INTROSCOPY OF VASCULAR NETWORK OF BLOOD CHANNEL Russian patent published in 2020 - IPC A61B5/402 A61B5/295 A61B5/1455 G06F17/14 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to methods of wavelet-introscopy of a vascular network of a blood stream. Electrocardiogram is placed on the patient's body, the biopotentials of which are amplified in the electrocardiographic signal (ECS) amplifier unit. ECS is then digitized by an ADC unit to which a data storage unit and a wi-fi device for wireless communication with the tablet PC are connected. Array of digital ECS data is subjected to wavelet transformation in a wavelet transformation unit and wavelet-section of the wavelet diagram of the ECS is performed in a wavelet-section of the wavelet diagram. Electrical activity of various segments of the conducting nervous system of the heart is detected in the ECS processing unit and displayed in a visualization unit. Patient's body is fitted with sensors of photoplethysmogram (PPG) and rheograms (RG), biosignals from which are amplified in appropriate units of amplifiers PPG and RG of biosignals. Biosignal data are then converted into digital form by an ADC unit. Wavelet transformation of biosignals is performed in a wavelet transformation unit. Within the cardiocycle, the skeletal function of the wavelet diagram is determined at each step of the wavelet transformation. Further, in the wavelet cross-section, units of the skeletal function are detected by multiple increase in the number of its branches at the branch points of the wavelet diagram, coordinates of which in the form of a jump time and the wavelet-transformation pitch correspond to the vascular network segment beginnings and are identified in the wavelet-section of the wavelet diagram unit. That is followed by visualizing the topology of all vascular network segments in a visualization unit.

EFFECT: providing visualization of the state of the vascular network of the patient's blood channel, as well as non-invasive detection of disturbances in the vascular network with higher accuracy of localization and rapid detection thereof, as well as obtaining detailed information on pulse wave passage and possibility of constant remote control of vascular network for evaluation of blood circulation in organs and tissues.
