Introduction Over 17 million individuals in the United States are affected with diabetes. While incurable, diabetes is manageable with proper monitoring. Currently, monitoring is performed through use of stand-alone blood glucose meters that allows a diabetic to monitor blood sugar levels on a periodic basis; the meter readings are either recorded into a log book or uploaded via proprietary software to a desktop computer. The purpose of this senior design project was to offer a new approach to patient self-monitoring through the development of a diabetes management system using the Handspring Visor Personal Digital Assistant (PDA). The design consists of a Springboard module containing blood glucose metering hardware and an accompanying software package that operates the module and allows for the storage and processing of data. The following sections outline the process followed by the senior design group in their development of the design.
Obtaining Information About Current Glucose Meters The first step to determine how current glucose meters obtain a reading was to look online for documentation. This allowed the group to review several different types of meters; however, it did not lead to any conclusive information about how an actual reading of a glucose level was obtained from a blood sample. After struggling with the search for information, the group turned to contacting the companies directly. Dr. David Kisor, a professor in the College of Pharmacy at Ohio Northern University, offered to help the group contact several different companies in the hope that one of them would be willing to form a partnership. Unfortunately, large drug companies move very slowly and none of the companies was able or willing to provide the design group with the necessary information in time. At this point, it was decided to examine the patent documentation from the several glucose meters the design group had already reviewed. One patent was found which had specifications on how the glucose level was obtained. The patent for the Bayer Glucometer Elite1 explicitly stated that the glucose reading could be obtained by applying 600 mV to the electrode containing the blood-testing strip, waiting five seconds, and then measuring the current flowing through the circuit. Figure 1 contains the graph of the response current to glucose concentration relationship as taken directly from the patent.
