便携式无创血糖检测方法

Experimental Study on Portable Non-Invasive Blood Glucose Measurement Method

为快速方便检测糖尿病人的血糖值,弥补使用有创血糖仪带来的污染和疼痛等不足,研究了一种无创血糖测量方法。该方法用波长为1 650 nm的红外光源透射人体指尖,接收光信号并进行光电信号转换,通过A/D(Analogue to-Digital)采集、串口通讯、数字滤波和傅立叶变换完成数据处理,并将血糖值存储和输出。经实验验证,该方法可实现对血糖浓度的基本测量,同时具有测量速度快、无污染和实用性强等优点,通过无创方式即可检测出血糖值,避免了有创检测带来的疼痛感。

In order to detect the blood glucose of diabetic patients quickly and easily,make up for the use of invasive blood glucose meter which brings pollution and pain and so on,we have designed a noninvasive blood glucose measurement method,using a 1 650 nm infrared light source to irradiate the human fingertip to receive light signals and carry on the photoelectric signal conversion,through A/D（Analogue to-Digital） acquisition and serial port communication,digital filter and the Fourier transform and so on to complete data processing,finally store the blood glucose value and output. Verified by the experiment,this method can realize the basic measurement of blood glucose concentration. It has the characteristics of high speed,no pollution and high practicability. The blood glucose value can be detected in a noninvasive way,which avoid the pain caused by invasive detection.
