Abstract

The invention discloses a non-invasive portable blood glucose meter based on an array CCD, comprising an LED light source, a lens, an optical fiber distance sensor, a finger groove, a driving circuit, an array CCD sensor, an ARM chip, a memory, a bluetooth chip and a power supply module. The invention is based on Beer-Lambert's law, uses an array CCD sensor to record the image data of the transmitted light of the finger under two conditions of the test light source and the reference light source, and obtains the influence of glucose on the absorbance through data processing. Use the optical fiber distance sensor to measure the size of the optical path length, and obtain the expression between the glucose concentration, absorbance, and optical path length through the curve fitting method. blood sugar concentration, display and save the results through the mobile device. The invention has the advantages of portability, low cost and simplicity.

Description

technical field [0001] The invention relates to a blood glucose concentration detection device, in particular to a non-invasive portable blood glucose meter based on an array CCD. Background technique [0002] According to statistics in 2015, there are currently about 114 million people with diabetes in my country, and diabetes has become one of the main problems that seriously affect the health of our citizens. Diabetes is harmful, mainly because of its serious complications, such as cardiovascular disease, kidney disease, eye disease, neuropathy and diabetic foot. There is currently no effective cure for diabetes, and controlling blood sugar levels is the only treatment. Timely detection of blood glucose concentration is of great significance for controlling diabetes, preventing complications, and improving the quality of life of diabetic patients. At present, in the field of detection of blood glucose concentration, most of them are detected by invasive blood glucose me...
