Noninvasive glucometer

Abstract

The invention relates to a noninvasive glucometer. An injection platform comprises insulin automatic injection equipment, blood oxygen saturation detection equipment, noninvasive blood sugar detection equipment and a DSP (digital signal processing) processing chip, wherein the blood oxygen saturation detection equipment and the noninvasive blood sugar detection equipment are used for extracting blood oxygen saturation data and blood sugar data of a tested person respectively; the DSP processing chip is connected with the insulin automatic injection equipment, the blood oxygen saturation detection equipment and the noninvasive blood sugar detection equipment respectively; and a blood oxygen supply state of the tested person is determined on the basis of the blood oxygen saturation data, and injection parameters of the insulin automatic injection equipment are determined on the basis of the blood sugar data. By virtue of the noninvasive glucometer provided by the invention, on the one hand, the blood oxygen supply condition of the tested person can be detected automatically, and on the other hand, adaptive injection control of insulin can be realized.

Description

technical field [0001] The invention relates to the field of insulin injection control, in particular to a non-invasive blood glucose meter. Background technique [0002] Blood sugar refers to the glucose contained in the blood. The digested glucose enters the blood from the small intestine and is transported to every cell in the body, which is the main energy source of the cells. The blood sugar concentration of normal people is relatively stable and falls within a determinable range of blood sugar concentration. [0003] Blood sugar must maintain a certain level in order to maintain the needs of various organs and tissues in the body. Blood sugar levels generally rise one to two hours after eating and are lowest at breakfast. Disorders of blood sugar concentration can lead to various diseases. Hyperglycemia with persistent high blood sugar concentration and hypoglycemia with too low blood sugar will have a serious impact on people's health, and persistent high blood sug...

AI Technical Summary

Problems solved by technology

[0004] There are some medical instruments for detecting blood sugar in the prior art, but these blood glucose meters have the following defects: (1) the detection mode is single, and only the blood sugar concentration can be detected; (2) the detection mechanism is backward, the structure redundancy is too high, and the accuracy meets (3) There is no control mechanism for blood sugar detection and insulin supply, and it is impossible to adaptively adjust the supply parameters of the measured person’s insulin according to the blood sugar content of the measured human body, such as supply speed, supply amount, etc. Manual observation of blood sugar levels and manual decision-making of insulin supply parameters are required, and the level of automation is lagging behind; (4) lack of wireless communication interfaces, and various parameters related to blood sugar cannot be fed back to the medical server in time, even if there are some simple wireless communication interfaces, such as Bluetooth The communication interface, its matching mechanism and connection mechanism are inefficient, and cannot meet the high-speed data transmission requirements of medical devices
