FIELD: medicine.
SUBSTANCE: invention refers to medical equipment, particularly to measurement of capillary and capillary blood flow characteristics. An apparatus comprises an image detector with an objective lens connected to a computer, a research area lighting system and a lodgement for a finger of a person being tested. A distinctive feature of the apparatus is that as the image detector is a CMOS-array with a shot change rate not less than 100 shot/sec, while the lighting system comprises a number of beam sources surrounding the lodgement, with their central beam axes making an illumination angle within the range (10÷12)° with a base of the lodgement. It allows improving image quality. The research area is chosen by inspecting the entire perivascular zones of a nail bed with making a shot package in each serial connection of one of a number of beam sources of the lighting system, and a dynamic condition of capillary blood flow is monitored at rate not less than 100 shot/second.
EFFECT: invention allows for more accurate determination of morphological and dynamic capillary and capillary blood flow characteristics.
