光电微损法检测血糖

Small-Invasive Photoelectric Detection of Blood Glucose

介绍了一种新型的光电微损法血糖检测技术 ,以此技术为基础研制的血糖仪以TI公司新推出的低功耗微处理器MSP4 30F4 13为核心。该仪器有 3个特点 :(1)在光电接受部分采用了类似分光计的单波长双检测管结构 ,以避免因发光二极管LED工作状态不稳定而带来的误差 ;(2 )通过多次比较法自动判断反应终止时间 ,即开始计算处理的时间 ;(3)可存储 5 0次测量结果。将其测量血糖浓度的结果与Prestige公司血糖仪的测量结果进行了对比。数据表明 ,其测量结果是准确可信的。光电式微损血糖仪具有操作简便 ,测定时间短 ,结果准确可靠 ,对器件一致性要求不高 ,低功耗等优点 ,是一种供糖尿病患者在家庭中监测控制自身血糖浓度的理想仪器。

A new type of photoelectric small-invasive blood glucose monitor was developed. This instrument is based on a 16 bit microprocessor MSP430F413 which belongs to a low-power microprocessor of the component family of Texas Instruments promotion recently. There are three advantages of this instrument: (1) using the method of two optical beams to decrease the influence of the LED's power fluctuation,. (2) using the multiple comparative method to determine the terminative time of enzymatic reaction and the start time of computing and processing, (3) to store a lot of measured data up to 50 samples. The data measured by this instrument were compared with Prestige blood glucose monitor, and the result shows that the accuracy and the reliability of this instrument is better. The specialties of this instrument are easy operation, getting results quickly, low-power and low cost. It is an ideal instrument for diabetic test and control of blood glucose concentration at home.
