The utility model relates to a non-invasive blood glucose meter device which uses the frequency spectrum of the nail wall micro image to detect blood glucose.It is confirmed by experiments.The microvascular circulatory system of the nail wall has many blood glucose characteristics.Through the finger holder,Electron microscope,Signal processing main board,Screen display and laser near-infrared light machine,Laser visible light machine and other photoelectric devices,First, the finger is fixed by the upper and lower cover of the finger holder.The location of the microvasculature in the circulation of the nail wall was confirmed by electron microscopy.Then the near-infrared light is emitted to the opposite side of the finger through the near-infrared laser light machine.The near-infrared light will refract due to the blood glucose value in the microvascular.Then the visible laser light machine is used to shoot the visible laser light to the front of the finger.The microvascular was irradiated to detect the Raman scattering caused by blood.We can use Raman spectroscopy to determine glucose.The high magnification microlaser image signal generated by the above two methods,The signal is then processed by an image a / D (analog to digital) converter on the signal processing main board and stored in memory.It is then processed as a processor element.Then enter the calculation processor to conduct infrared imaging spectrum and Raman imaging spectrum analysis with software, so that the blood sugar value can be calculated and analyzed.So as to get the blood sugar value.一種以甲壁顯微影像頻譜檢測之非侵入式血糖儀裝置，經實驗證實，甲壁微血管循環系統具有許多的血糖特徵，透過手指固定器、電子顯微鏡、訊號處理主機板、螢幕顯示器以及雷射近紅外光光機、雷射可見光光機等光電裝置，先由手指固定器內含之上下罩殼固定手指，經由電子顯微鏡顯微放大影像後確認甲壁循環微血管之位置，再經由近紅外光雷射光光機向手指反面發射雷射近紅外光，該近紅外光會因微血管內血液之血糖值產生折射，接著再以可見光雷射光光機向手指正面發射可見光雷射光，照射微血管以檢測血液造成之拉曼(Raman)散射，即可利用拉曼之光譜測定葡萄糖，藉由以上兩種方式產生之高放大倍率顯微雷射影像訊號，再將該訊號經由訊號處理主機板進行影像A/D(類比轉為數位)變換器處理並存入記憶器，接著以處理器元件處理，再進入演算處理器以軟體進行紅外成像光譜以及拉曼成像光譜分析如此便可運算分析出血糖值，從而求出血糖值。
