Embodiment Construction

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0023] The main principle of the method of the present invention is that in order to obtain a more stable and accurate blood sugar level and reduce the influence of various external factors such as ambient temperature, humidity, and plasma concentration on the measured value of blood sugar, the method of the present invention uses an electrochemical analyzer to monitor the reaction process in real time When the detection current is stable, the sample current value is extracted and averaged, and the real-time amplified voltage value is obtained through the voltage amplifier circuit, and then the measured value of the blood sugar value is obtained by analog-to-digital conversion and function conversion.

[0024] The microstructure of the blood glucose test paper that the present invention adopts is as figure 1 As shown, the upper surface is a layer o...

Abstract

The invention discloses a stable evaluation method for electronic blood glucose measurement, which belongs to the field of medical measurement devices. The method comprises the steps of monitoring the variation of current in the reaction process in real time by utilizing an electrochemical analyzer, extracting n sample current values under the situation that the detection current is stable, getting an average value, obtaining a real-time amplified voltage value through a voltage amplifier, and obtaining a measurement value of the blood glucose through an analog-digital conversion and functional conversion method. By adopting the method, the error of the blood glucose electronic measurement caused by uncontrollable factors can be reduced, so that a stable and precise blood glucose value can be obtained.

Description

technical field [0001] The invention belongs to the field of medical measuring instruments, and more precisely, the invention relates to a method for stabilizing the measurement accuracy of a portable blood glucose meter. Background technique [0002] Diabetes mellitus is a metabolic disease characterized by hyperglycemia due to defects in insulin secretion or insulin action. In the past 30 years, the prevalence of diabetes in my country has increased significantly. The prevalence of diabetes in 1980 was about 0.7%. From 2007 to 2008, the prevalence of diabetes among adults over the age of 20 in my country reached 9.7%. In 2010, there were 92 million people with diabetes and 148 million people with prediabetes in my country. Diabetes has become one of the main problems seriously affecting public health in China. [0003] The current accurate blood glucose measuring instrument is the blood glucose biochemical instrument used in the hospital. Its main advantage is that the ...
