A portable blood glucose meter based on mems

Abstract

The present invention relates to the technical field of blood glucose meters, in particular to a MEMS-based portable blood glucose meter, including a spectrum box, a positioning buckle and a controller; due to the complexity of human physiology and measurement conditions, it is necessary to process a large amount of measured data, It is not convenient to be applied to small-volume portable blood glucose meters, and the detection accuracy of the spectrum is difficult to meet clinical requirements, which also limits the application of non-invasive portable blood glucose meters; The amount of displacement, thereby enhancing the content state of glucose molecules in the flowing blood, and the installed MEMS photoreceptor reduces the volume of the spectrum box, which is convenient for application in portable blood glucose meters. With the constant temperature function of the positioning buckle, it stabilizes The collected blood glucose value improves the use effect of the MEMS-based portable blood glucose meter.

technical field [0001] The invention relates to the technical field of blood glucose meters, in particular to a MEMS-based portable blood glucose meter. Background technique [0002] At present, there is no medical method to completely cure diabetes. It is mainly through self-monitoring of blood sugar and timely adjustment of the dosage of oral drugs and insulin to prevent or reduce the impact of complications. The existing blood sugar detection methods generally use acupuncture.

[0002] At present, there is no medical method to completely cure diabetes. It is mainly through self-monitoring of blood sugar and timely adjustment of the dosage of oral drugs and insulin to prevent or reduce the impact of complications. The existing blood sugar detection methods generally use acupuncture. Take blood from fingertips and use a rapid blood glucose meter to measure, but it will cause pain to the patient and the risk of infection in the process of frequent daily measurement, and limit the number of tests that can be performed per unit time, thereby reducing the mastery Accuracy of blood glucose parameters

[0003] At present, a method of non-invasive blood sugar detection has also appeared, which uses the penetration ability of infrared spectrum to human tissue and cooperates with the characteristic absorption of glucose molecules in the near-infrared region to optically detect the blood sugar content, but due to the complex physiological conditions of the human body Due to the differences in conditions and measurement conditions, it is necessary to process a large amount of measured data, which is not easy to apply to portable blood glucose meters, and the accuracy of spectral detection methods is also difficult to meet clinical requirements, which also limits the development of non-invasive portable blood glucose meters.

[0004] There are also some technical solutions for portable blood glucose meters in the prior art. For example, a Chinese patent with application number 2010101430723 discloses a near-infrared spectrum transmission method and device for non-invasively measuring human blood sugar. The electronic switch switches the power supply, and two The beam wavelengths λ1 and λ2 of different wavelengths of light-emitting diodes; before the electronic switch is switched, the photoelectric tube and analyzer record the beam intensities I01 and I02 of the two light-emitting diodes; After uniform mixing, the switching of the electronic switch passes through the human body in time-sharing, and the electronic switch switching moment records the beam intensities I1 and I2 of the wavelength λ1 and λ2 beams after passing through the same human body; the analyzer passes through the beam intensities I01, I02, I1 and The I2 value calculates the human body medium attenuation coefficient K1 value related to the blood sugar value. Based on the correlation between the K1 value and the human blood sugar value and the human body temperature at that time, the influence of body temperature changes is corrected. The functional relational expression of the value calculates the blood glucose value in daily measurement; however, this scheme does not consider the large number of correction calculations required for the measured near-infrared spectrum under the influence of temperature, and the local temperature difference on the skin surface reduces the measurement accuracy of blood glucose, which limits The effect of using the blood glucose meter
