Movable noninvasive system for detecting blood sugar

Abstract

The invention provides a movable noninvasive system for detecting blood sugar. The detection system comprises a laser modulating module, an optical rotation compensation module, an optical sensitivitymodule, a signal processing module and a wireless transmission module. Signals detected by a photoelectric detector 106 enter a signal processing system which consists of a signal detection part 201,a modulating / demodulating part 202 and a wireless programmable system chip 203; the system chip 203 judges the existence of the signal and controls a power driving part 204 of a Faraday coil to compensate the laser optical rotation; the blood sugar concentration is characterized by the voltage applied to the Faraday coil; furthermore, the interference of the leakage current is overcome by settinga threshold, and the traditional technical bottleneck of measuring the slight change of the light intensity. The movable noninvasive system for detecting blood sugar has high integration and small volume, and has the advantages of non-invasiveness, quick detection, wireless transmission and the like, can realize an in-vivo and real-time continuous detection on the blood sugar concentration underthe normal physiological state of a human body, and is extremely suitable for movable detection of movable patients.

Description

technical field [0001] The invention relates to a small-scale non-invasive measurement system of human blood sugar content based on wireless local area network technology. It does not need to take blood samples, but only needs to put the test system on a person's finger, and can carry out continuous non-invasive measurement of blood sugar content, and the result will be recorded in real time. Wirelessly send to the management terminal, suitable for continuous detection of blood glucose of active patients. Background technique [0002] At present, the measurement of blood sugar content in the human body is usually invasive. In hospitals, blood is usually drawn, and then the blood sugar in the blood is catalyzed and oxidized by biochemical methods, and the blood sugar concentration is realized in an indirect way by measuring the oxygen consumption or the amount of the product. Characterization . With the development of electronic technology and biochemical technology, a minim...

In terms of non-invasive detection of blood sugar, a non-invasive detection method of human subcutaneous tissue fluid reverse osmosis was proposed by researchers, but this method needs to be in close contact with the skin for a long time, which may easily cause skin discomfort or even local inflammation, so related technologies still need to be developed. to further improve

For the vast majority of diabetic patients, they can move freely, but they need to monitor their blood sugar status in real time; in addition, for the glucose tolerance test of some insulin resistant people, the current experimental method is: first measure fasting blood sugar, and then 5 minutes Let the patient drink a certain concentration of glucose water within a certain amount, and take blood once 30 minutes, 1 hour, and 2 hours after drinking the sugar water to test the blood sugar concentration in the blood. This undoubtedly increases the pain of the subject and cannot be true Response to the glucose tolerance characteristics of subjects in their normal life conditions
