Research On Wireless Portable Blood Glucose Meter

With the global increase of the number of potential diabetics and people withdiabetes, countries in the world pay more and more attention to the prevention andtreatment of diabetes. Blood glucose self-monitoring is an important means of thecontrol of diabetes. Because portable blood glucose meter has many advantages such asusing just a little blood, small, fast, cheap, easy to operate, and so forth, it alreadybecame the first choice for blood sugar self-monitoring. At present, most of the portableblood glucose meters on the market do not have instant data communication function,which result in doctors and guardians can not obtain the patient’s condition timely tocontrol the development of the diabetes more precisely.In this paper, a wireless portable blood glucose meter which can upload thepatient’s blood sugar data in real time developed by combination with the current rapiddeveloped wireless communication technologies is introduced. The current researchstatuses in related fields are described in detail at first. And then, the requirements ofthe wireless portable blood glucose meter are defined and the design is proposedaccording to its characteristics. Then the design and implementation of the hardwareand software of the wireless portable blood glucose meter is explained at length. Thehardware is designed with Protel99SE EDA tool, and the software is developed usingthe C language on theAVR Studio4+open source WinAVR development environment,and simulated and debugged by the JTAGICE mkII simulation tool. The hardwareconsists of MCU (Micro Control Unit), real time clock(RTC), dot matrix LCD, buzzer,power supply, serial ports, keys, antennas, CDMA module, temperature sensor, bloodglucose data acquisition module; the software is designed with hierarchical andmodular design method and implemented using the Finite State Machine model andevent-driven programming paradigms on the basis of the completed hardware. Afterthat, the process of calculating the glucose and temperature algorithms by performingexperiments with the implemented hardware and software is shown.In the end, the paper records the functional testing and performance testing of thewireless portable blood glucose meter. It is verified by the tests results that theimplementation conforms to the design requirements and the wireless portable bloodglucose meter can be used as a powerful tool for blood glucose self-testing in a varietyof application scenarios.
