APPARATUS FOR in vivo NON-INVASIVE ANALYSIS BY RAMAN SCATTERING SPECTROSCOPY Russian patent published in 2015 - IPC A61B5/145 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical diagnostics. An apparatus for in vivo non-invasive analysis of an individual's skin interstitial fluid by means of Raman scattering spectroscopy comprises a light source, optical components detecting a light path from the above light source to a measuring point, a light detection unit, optical components detecting a Raman scattered light return path from the above measuring point to the above light detection unit, and a skin coupling element having a distal surface to determine the position of the above optical components detecting the return path in relation of the skin surface when in use. The optical components detecting the Raman scattered light return path are configured to permit the light scattered nearby the above measuring point to the above light detection unit selectively so that at least 50% of the Raman scattered light received by the light detection unit is generated at a depth of 60 to 400 mcm under the above distal surface of the skin coupling element. The optical components detecting the light path from the light source to the measuring point under the skin surface are configured to focus the light emitted by the light source at a depth of 200 to 300 mcm under the skin surface. What is disclosed is a method for in vivo non-invasive glucose analysis.

EFFECT: technical effect consists in maintaining t correct adjustment and using the adjustment for various individuals.
