MSP430-Based Blood Glucose Tester Design And Application

Diabetes which is one of the four diseases is harmful to human health, their symptoms is urine of blood glucose abnormalities. The current global diabetes has more than 200 million people, but China has been diagnosed with diabetes is approximately 5.5% of the total population, and these data is also kept linear growth.Modern medical study found that the control of blood sugar of can reduce diabetic complications. However, there is very little to the hospital for monitoring diabetic blood glucose, leading to disease progression is difficult to control, or even very likely a direct threat to the lives of their patients.Currently, in the United States and other developed countries, many diabetic patients have a portable hand-held blood glucose testing instrument, which can thus detect a patient's own blood sugar glucose status, so that you can prevent significant deterioration of diabetes mellitus, combined with doctor treatment, thus reasonable control of diabetes and conditions. Therefore, an efficient portable blood glucose monitoring equipment as necessary.Pattern of blood glucose at home and abroad various instruments and variety, and the works are basically the same, but due to different blood glucose test meter on the chip select is different, resulting in testing speed and accuracy of test results somewhat different. In order to improve blood sugar testers test speed, increase blood glucose tester measurement accuracy, resulting in faster and more accurate blood glucose testing the human body, in addition to processing test test strip (bio-sensors, used in conjunction with blood glucose testing equipment) to process ensure stability of production environment and to minimize the impact of environment on the production process, the use of more rapid and precise test chip also can improve the speed and accuracy.For these reasons, this paper which is based on TI's ultra low power MSP430F437 blood sugar testing equipment, this article describes a portable blood glucose meter blood glucose levels can be completed fast and accurate detection, and less blood is beneficial to patients self-monitoring. This design uses MSP430F437 MCU, together with the blood glucose monitoring circuits, memory circuits and good man-machine interface, simple operation, low power consumption, high speed, etc, and can store up to 30 historical data, patient-friendly control of their own blood glucose concentration trends, and reasonable treatment.This article describes the characteristics of blood glucose testing equipment is cheap, fast, high precision, therefore the application of high research value. The article first introduces the blood glucose monitoring technology, history, current situation and future development trends, and describes the blood glucose monitoring used in this principle; and then introduced in the design principle of the weak current detection, low-power design principles and automatic identification test Code Article circuit design ideas and made the overall design goals and technical specifications; and then around the overall objectives, details of the hardware and software design ideas; Finally, data analysis, blood glucose values obtained the formula by instrument verification.
