Abstract

The invention discloses a noninvasive portable glucometer based on an array CCD. The glucometer comprises an LED light source, a lens, an optical fiber distance sensor, a finger groove, a drive circuit, an array CCD sensor, an ARM chip, a memory, a Bluetooth chip and a power source module. According to the noninvasive portable glucometer based on the array CCD, on the basis of a Beer-Lambert law,the array CCD sensor is used for recording image data of transmission light of a finger separately under the two conditions of a testing light source and a reference light source. The data is processed, and therefore glucose's influence on absorbance is obtained. The optical fiber distance sensor is used for measuring the length of the optical path length. A curve fit method is used for obtainingan expression among glucose concentration, absorbance and the optical path length. The expression can be utilized for calculating the glucose concentration of a testee according to the data of the absorbance and the optical path length. A result is displayed and stored through a mobile device. The noninvasive portable glucometer based on the array CCD has the advantages of being portable, low in cost and simple.

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...
