| titleOfInvention | Apparatus and method for measuring vascular endothelial function |
| abstract | The present invention relates to an apparatus and a method for measuring vascular endothelial function, and the technical problem to be solved is to calculate tissue perfusion after normal and vascular expansion, and then compare the two perfusion to calculate the increase in blood flow of the vascular endothelial cells. To provide a device and method for measuring vascular endothelial function that can diagnose the function.n n n To this end, the apparatus for measuring vascular endothelial function according to the present invention includes a light leakage preventing unit including a light source for irradiating light of a predetermined wavelength to a living body in which a ICG is injected into the housing, and the living body generated by the ICG and the light source. A data acquisition unit including a band pass filter for passing only a near infrared wavelength and an image sensor for detecting a fluorescence signal passing through the band pass filter, and an electrical signal of the image sensor with an AIF of ICG concentration and time dependent Numerical means for processing the fluorescence intensity, determination means for determining the AIF representative point as a standard measure for measuring the perfusion rate from the fluorescence intensity over the processed time, and arithmetic means for calculating the perfusion rate with the output data of the determination means. And a data output unit configured to output the perfusion rate of the data processing unit and the data processing unit. The light protection unit includes a hand rest that fixes the back of the hand or the palm of the living body so that the ICG image can be obtained from the back of the hand or the palm of the hand, or the ICG image can be obtained only from the end of a specific finger.n n n n Vascular endothelial cells, hand restraint, ICG concentration, AIF representative point, perfusion rate, blood flow |
