Problems solved by technology

[0010] At present, the method of blood glucose detection and calibration is to establish a corresponding relationship between the blood glucose values ​​of finger blood or venous blood collected several times and the tissue scattering coefficient at the same time, and to obtain the relevant areas of different depths of the skin through correlation calculation for subsequent blood glucose detection. The calibration method takes a long time, usually 2-3 hours, and requires multiple invasive blood collections, which not only increases the pain of the testee, but also increases the risk of infection

Embodiment Construction

[0033] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] Before performing optical non-invasive blood glucose detection, separate calibration is required, and the calibration data is only applicable to individuals and cannot be used universally.

[0035] Please refer to figure 1 , in one embodiment, provide a kind of blood glucose detec...

Abstract

The invention discloses a blood glucose testing and calibrating method and system. According to the blood glucose testing and calibrating method and system, the related coefficients of the scattering coefficients of different depth tissue of skin and the temperature can be calculated, and the tissue area which is sensitive to the change of both the temperature and the blood glucose of a human body can be found through analysis to the related coefficients. A high correlation area obtained by correlation analysis can be used as a calibration area for noninvasive blood glucose testing and is used for subsequent blood glucose testing and the like. The blood glucose testing and calibrating method greatly simplifies the noninvasive blood glucose testing and calibrating process, the calibrating time is greatly shortened, the pain of a diabetic patient is relieved at a certain degree, and the risk of infection is lowered.

Description

technical field [0001] The invention relates to the field of blood sugar detection, in particular to a blood sugar detection and calibration method and system. Background technique [0002] Diabetes is a frequently-occurring disease among middle-aged and elderly people. With the improvement of people's living standards, the incidence of diabetes is also increasing. The World Health Organization lists diabetes, tumors and cardiovascular and cerebrovascular diseases as three major diseases worldwide. Finding a method for detecting blood sugar concentration is of great significance for the prevention and treatment of diabetes. At present, the most widely used blood glucose concentration detection method is invasive measurement. The main method of invasive detection is to rely on electrochemical methods to detect the patient's finger blood to obtain the patient's blood glucose concentration value. This method can realize the detection of the blood glucose concentration value a...
