Abstract

Provided are a blood glucose detection system and detection method. At present, blood glucose detection is carried out by venous blood glucose detection and capillary blood glucose detection, but thedetection method is inaccurate, and a patient cannot be injected with insulin well according to the blood glucose content. The blood glucose detection system comprises a CPU (1) and an LED circuit (9); the CPU (1) is electrically connected with the LED circuit and a filter circuit (8), the filter circuit is electrically connected with a differential amplifying circuit (7), the differential amplifying circuit is electrically connected with two logarithmic amplifying circuits (6), the logarithmic amplifying circuits are electrically connected with a filter (5), the filter is electrically connected with a Y coupler (4), and the Y coupler is electrically connected with an optical fiber sensor (3). The blood glucose detection system and detection method are used for blood glucose detection.

Description

Technical field: [0001] The invention relates to a blood sugar detection system and a detection method, belonging to the field of blood sugar detection. Background technique: [0002] There are currently 170 million diabetic patients in the world, and diabetes has become the fifth leading cause of death in the world ， Insulin therapy is the main treatment for all insulin-dependent diabetics, and the basis for determining insulin dose is to closely monitor the control of blood sugar. At present, venous blood glucose measurement and capillary blood glucose measurement are mostly used for blood glucose detection, but this detection method Inaccurate, patients can not inject insulin well according to blood sugar content. Invention content: [0003] The purpose of the present invention is to solve the problem of inaccurate detection results of existing blood glucose detection methods, and provide a blood glucose detection system and detection method with accurate detection and...
