摘要：
The invention relates to medical engineering, in particular to devices for measuring characteristics of the capillary and capillary flow implemented by means of optical inspection, and can be used for noninvasive studies of capillary blood flow parameters for the diagnosis of various diseasesThe proposed device for non-invasive investigation of the characteristics of the capillaries and capillary blood flow, comprising a housing, image receiver with a video camera connected to the computer, and the objective lens, illumination field research system and attached to the body cradle to accommodate a finger of the subject so that the nail bed was drawn to the lens receiver images and a temperature sensor, which lighting system comprises at least two light source blocks with their power radiation sources MY ying narrow band with a central wavelength in the spectral range 530-540 nm radiation sources operate in the pulsed mode, their impulses are synchronized with the video camera frames, the radiation sources are arranged so that the optical axis of the radiation are at an angle of 45 ° to the vertical axis in the plane, perpendicular to the direction of the subject finger placement, in which is used as a lens of zoom optical system with the possibility of stepless adjustment of its increase, within the working distance 40 50 mm.The radiation sources are LEDs focusing systems, each of which comprises at least two lenses. In using a non-contact temperature sensor connected to the computer as a temperature sensor. The apparatus further comprises a laser marker, an optical radiation axis is aligned with the optical axis of the observation.Utility model simplifies the inspection process, reduce its holding time, improve the clarity of the image and, thereby, improve the accuracy of the device in the determination of the morphological and dynamical characteristics of the capillaries and capillary blood flow, improve the accuracy of diagnosis.Полезная модель относится к област
