Blood glucose in chemical medicine equipments are expensive and complicated to operate

so a new portable intelligent blood glucose meter is developed.The meter immobilizes enzyme on the pole and detects the resultant weak current.After amplification

filtering

A/D conversion and the data processing based on MSP430

the measuring result is displayed on LCD.An artificial intelligence chip that solidifies diabetes knowledge library can give conclusions and issues.Temperature compensation and automatic rectification are applied.The measuring range of the glucose meter is from 2.2 mmol/L to 27.8 mmol/L

single blood sample is 3

5

μL and the single test time is no more than 25 s.Experiments show that the results of the meter are consistent with the ones of the large-scale biochemical blood glucose analyzer.
