Design implementation of a low cost blood glucose meter with high accuracy

摘要

Diabetes Mellitus mostly known as ??Diabetes?? is a worldwide common and serious health issue. Across the world approximately 175 million people at present are with diabetes and this will increase to 366 million by the year 2030 according to World Health Organization statistics. People suffering from diabetes are solely dependent on exact blood glucose concentration information. Glucometer is a device which helps to detect blood sugar levels in human body. In developed countries people widely use this medical device. But in developing countries like Bangladesh the usages of this helpful devices is limited to a very few people; due to illiteracy, cost, publicity etc. In this paper, a real time blood glucose meter is designed & implemented which is very low in cost, targeting the poor people in developing and underdeveloped countries. This proposed meter uses transcendental concentration equation over the linear equation used in existing commercial meters. Due to this, the average deviation of result is much smaller than the commercial one. Result shows that the proposed meter gives around 93% accuracy with pathological data tested over 38 persons. Total cost of the proposed glucometer is only 5 USD so that poor people can have an easy access to this meter.
