DEVICE FOR MEASURING BLOOD FLOW IN BODY TISSUE Russian patent published in 2014 - IPC A61B5/1459 

FIELD: medicine.

SUBSTANCE: invention relates to devices for measuring blood flow through body tissue. Device contains catheter, which has head for introduction into body tissue, and central component, which has surface for bringing out radiation, to which light guide, and reflecting surface, which is located opposite surface for bringing out radiation and is oriented at least partially with inclination with respect to longitudinal axis of light guide. Light guide is installed with possibility to direct beam of radiation, emitted by radiation source, onto reflecting surface, with deviation by reflecting surface of said radiation beam, which can be directed into body tissue. Radiation beam, reflected by body tissue, can be directed by reflecting surface into light guide. Head of catheter is divided into introduced part and adjacent to it connecting part, with several cavities being made in surface of introduced part. Diameter of introduced part increases towards connecting part, and cavities in introduced part are made with formation between them on surface of catheter head of bridges, extended towards connecting part.

EFFECT: application of invention makes it possible to reduce trauma of brain tissue in the process of carrying out measurements of blood flow and increase effectiveness of measurements.
