APPARATUS FOR FLUORESCENT SPECTROSCOPY OF BIOLOGICAL TISSUE Russian patent published in 2015 - IPC G01N21/64 A61B6/08 G01J3/02 

FIELD: physics.

SUBSTANCE: apparatus comprises a fluorescent-reflective spectrometer, which includes an illumination system and spectrometric system connected to a Y-shaped fibre-optic probe. The apparatus is further provided with two channels, one of which intended for supplying liquid to the investigated organ to wash off blood and is connected to a pump, and the other channel is intended for sucking the liquid and blood from the investigated organ and is connected to a pump. Both channels and the distal end of the fibre-optic probe are placed in a ferrule to form a fibre-optic probe. The ferrule is in the form of a metal cylinder with a socket at the end which is adjacent to the investigated organ.

EFFECT: high accuracy and consistency of measurement results, enabling investigation of the heart within the body.
