High-precision biosensing device for measuring blood sugar level

Abstract

The invention relates to a high-precision biosensing device for measuring the blood sugar level. The device comprises a main body, a display screen, an operation panel, a piece of test paper, and a support plate. The main body is in a shape like cuboid. The display screen and the operation panel are disposed at the main body; a through hole is formed in one side of the main body; and the test paper passes through the through hole. A measuring device is disposed in the main body and is connected with the test paper. The support plate is perpendicular to a plane on which one side with the through hole of the main body is located; the support plate is fixedly connected with one side with the through hole of the main body. An auxiliary mechanism is arranged on the support plate and is arrangedat one side, being close to the axis of the through hole, of the support plate. Besides, a dehumidification mechanism is arranged in the main body. According to the high-precision biosensing device,excessive extrusion is avoided by the auxiliary mechanism; and the dehumidification function of the test paper is realized by the dehumidification mechanism.

Description

technical field [0001] The invention relates to the field of biological sensing equipment, in particular to a high-precision biological sensing equipment for measuring blood sugar levels. Background technique [0002] A biosensor is an instrument that is sensitive to biological substances and converts its concentration into an electrical signal for detection, while a blood glucose meter is a type of biosensing device. A blood glucose meter is an electronic instrument that measures blood sugar levels. Divided into photoelectric type and electrode type. [0003] Existing blood glucose meters need to take blood from the user during use, and if the blood is taken too much, the interstitial fluid will be squeezed out and mixed with the blood, resulting in low blood sugar test values ​​and lower measurement accuracy. , the influence of test strips on the test results is the most critical of all problems. Most of the detection errors are caused by the deterioration and denaturatio...

[0003] Existing blood glucose meters need to take blood from the user during use, and if the blood is taken too much, the interstitial fluid will be squeezed out and mixed with the blood, resulting in low blood sugar test values ​​and lower measurement accuracy. , the influence of test strips on the test results is the most critical of all problems. Most of the detection errors are caused by the deterioration and denaturation of the test paper. Glucose reacts and displays the color, and the blood glucose meter displays the reading after resolution, but when the test paper is damp, it will affect the displayed color, which will also reduce the measurement accuracy
