Embodiment Construction

[0021] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0022] Please refer to figure 1 , is a non-invasive blood sugar detection system disclosed in this embodiment, including: a signal collector 1 and a non-invasive blood sugar detection device 2, wherein: the signal collector 1 is used to collect and output pulse wave signals of the subject to be tested. The non-invasive blood glucose detection device 2 is connected with the signal collector 1, and is used to detect the pulse wave signal output by the signal collector 1, so as to obtain the blood glucose concentration of the test subject.

[0023] In a preferred embodiment, a front-end signal processing circuit 2 may also be connected between the signal collector 1 and the non-invasive blood glucose detection device 2, and the front-end signal processing circuit 2 is used for pre-processing the pulse wave signal collected and output...

Abstract

A non-invasive blood glucose detection method comprises the steps that a pulse wave signal is obtained, and blood glucose concentration information of a sample to be detected is borne by the pulse wave signal; the obtained pulse wave signal is detected through first detection to obtain an initial detection value of blood glucose concentration; the obtained pulse wave signal is detected through second detection to obtain a detection interval which the blood glucose concentration belongs to; whether the detection belongs to the detection interval or not is judged, and if yes, the initial detection value serves as the blood glucose concentration value borne by the pulse wave signal. Due to the fact that judgment is conducted on the interval which the initial detection value belongs to, interference to the blood glucose concentration caused by other components can be effectively reduced, and the precision and the accuracy of blood glucose concentration detection are improved. The invention further discloses a non-invasive blood glucose detection device and system.

Description

technical field [0001] The invention relates to the field of medical testing, in particular to a non-invasive blood sugar testing method, device and system. Background technique [0002] With the development of social economy, people's living standards are gradually improving, but there are also some diseases that follow. At present, diabetes has become one of the main diseases that endanger human health in modern society. Excessively high or low blood sugar not only affects the patient's metabolism, but also has some complications, such as cardiovascular disease and neuropathy, which pose a great threat to the patient's health. According to the report of the World Health Organization, there will be 300 million diabetic patients in the world by 2025, among which there will be a large part of diabetic patients in China. In recent years, diabetic patients not only exist among some elderly people, but also some young people have begun to have diabetes symptoms. Diabetes is a ...
