DEVICE FOR METROLOGICAL CONTROL OF STATE OF LASER DOPPLER FLOWMETRY DEVICES Russian patent published in 2013 - IPC A61B5/02 A61B5/00 G01N21/49 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to device for metrological control of state of laser Doppler flowmetry devices for non-invasive diagnostics of blood microcirculation of human and animal system. Device represents laminated construction from different solid materials with different light-diffusing optical properties, which contains immovable upper and lower layers and placed between them middle layer, which is moved by electromechanical moving device. Construction is additionally provided with layer with light absorbing covering. Moving device is made in form of electromechanical transformer of electric signal into mechanical vibrations in 0.1 Hz - 20 kHz frequency band. Middle layer is located with 0.1-1 mm clearance from upper layer and is placed on layer with light-absorbing covering, which is located on the surface of electromechanical transformer of electric signal into mechanical vibrations.

EFFECT: application of device makes it possible to essentially increase reliability of control of state of laser Doppler flowmetry devices.
