基于光电容积脉搏波的无创血糖测量研究

目前临床使用的血糖测量方法是采用直接抽取患者血液, 根据生物化学反应原理测量血糖, 这种有创测量方法存在疼痛、易感染、不能连续测量等问题。根据光电容积脉搏波检测理论, 研究了一种血糖测量方法,实现临床无创连续血糖测量。该方法采用波长为805 nm 和940 nm 两束近红外光透射患者手指, 其中805 nm为血糖敏感波长, 940 nm 为参考波长。从透射光中提取与血糖有关的信息进行数据处理并进行标定, 计算血糖值。经实验验证, 该方法能实现连续的无创血糖测量。

Research on Non-Invasive Blood Glucose Measurement Based on Photoplethysmograph

The clinical method of blood glucose measurement at present is extracting blood from the patients, which is based on the principle of biochemical reaction. This invasive methord is painful, susceptible and discontinuous. To deal with these problems, we focus on a non-invasive way on the strength of the photoplethysmography detection theory by irradiating the finger with two beams of near infrared lights of 805 nm and 940 nm. The wave of 805 nm is sensitive to glucose, while the 940 nm one acts as the reference. By processing the information of the blood glucose extracted from the transmitted lights, the blood glucose value can be calculated.Experiments have convinced that the continuous non-invasive blood glucose measurement can be achieved.
