METHOD OF COMPLEX ASSESSMENT OF THE MICROCIRCULATORY PATHWAY Russian patent published in 2018 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine. Microcirculatory channel is examined by means of an infrared thermometer and a spectrocapillaroscope in a volume visualization mode, followed by 3D modeling of the microvascular bed. Measure the local temperature in the study area. Throughout the study, the total temperature, the concentration of oxyhemoglobin, the activity of adhesion factors in the perivascular zone are measured. Simultaneously, an assessment is made of the vegetative nervous system with the definition of parameters: the standard deviation from the mean value of the cardiointervals, the index of centralization and the index of stress of vegetative regulation systems, the square root of the sum of the squares of the difference in the successive pairs of cardiointervals, the deviation of the duration of the cardiointervals. Define microcirculatory parameters: the unevenness of the caliber of the arterial and venous part of the capillaries, unevenness of the caliber of the capillaries proper, the coefficient of tortuosity of the arterial and venous part of the capillaries, and the arteriolo-venular coefficient. distance between capillaries, diameter of the leading and withdrawing parts of the capillaries, the diameter of the capillaries, the distance between the arterial and venous parts of the capillaries, the total coefficient of transverse deformation of the capillaries, velocity of blood flow in the capillary bed, the length of the perivascular zone. Indicators are also determined: the degree of stasis, the leukocyte-platelet index, the presence and area of hemorrhages, the presence and area of edema.

EFFECT: method allows to objectively and informatively conduct a comprehensive assessment of the microcirculatory channel by using an infrared thermometer and a spectrocapillaroscope in a three-dimensional visualization mode with subsequent 3D modeling of the microvascular bed and evaluation of the most significant indicators.
