摘要
根据能量代谢守恒法无创检测血糖浓度的原理,设计出一规格为60 mm×30 mm×85.5 mm的无创血糖检测传感器集成器。主要由底座、指表血流流速检测区、人体指部代谢率检测区、指端血氧红外检测区、电路连接区和信号输入输出区组成。由温度传感器、湿度传感器、辐射温度传感器、双波长(660 nm/905 nm)的红外发射及接收传感器在一定实施条件下集成得到。通过本集成器实现了对血糖浓度的无创伤检测,经20例临床初步实验,结果表明:与AMS-AUTOLAB18全自动生化分析仪的相关系数R达到了0.807,具有较好的相关性和一致性。经误差统计分析发现其平均相对误差为7.0%,平均绝对误差小于0.5,证明检测结果具有较高的精确度。
Based on the method of conservation of energy metabolism （COEM）, an integrator of sensors is designed to measure the blood sugar level non-invasively,which size is 60 mm ×30 mm×85.5 mm. Including the base, the blood flow measuring region of the finger surface, the metabolism rate measuring region of the part of finger, the oxygen saturation infrared measuring region of the part of finger, the link region of circuit and the signal in-out region. The integrator is integrated by the temperature sensors, the humidity sensors, the radiation sensors, the dual emitter photodetectors （660 nm/905 nm）at some implementary conditions. Blood sugar level is achieved non-invasively by the integrator. The results of 20 preliminary clinical experimentations suggest that the correlative coefficient is up to 0. 807 between the integrator and automatic biochemical analyzer（AUTOLAB18）, which shows strong correlation and good coherence. The average relative error is 7.0 %, and the boundary of average relative different is less than 0.5 through the statistical error analysis, which shows the measuremental results is effective and accurate.
