Patent ID: 7672702

Claim:
A noninvasive in vivo measuring system comprising: a tissue modulation unit configured to apply a pressure on a tissue; a hemoglobin (Hb) measuring unit configured to analyze an amount of absorption of electromagnetic waves on a first portion of the tissue before and after the application of the pressure by the tissue modulation unit, and configured to measure a Hb concentration of the tissue; and a Raman-fluorescence (R-F) measuring unit configured to measure a blood sugar concentration by analyzing Raman spectra based on a reflection of a laser irradiated on a second portion of the tissue before and after the application of the pressure by the tissue modulation unit, and configured to calculate a final blood sugar level by correcting the blood sugar concentration measurement, based on the measured Hb concentration, wherein the R-F measuring unit is configured to calculate the final blood sugar level by increasingly correcting the blood sugar concentration measurement, having been measured based on the Raman spectra, when the Hb concentration is greater than a predetermined threshold value, and is configured to calculate the final blood sugar level by decreasingly correcting the blood sugar concentration measurement, having been measured based on the Raman spectra, when the Hb concentration is less than the predetermined threshold value.
