PhotoPlethysmoGraphy based Low-Cost Glucometer with Haemoglobin Measurement

The Human body is made of tissues, fluids, hormones, organs and organ structures. To sustain a healthy life, people need to be in conscious of their health to prevent diseases. Various medical devices are used for tracking the health of people. Blood glucose level is essential need to track a patient's metabolism. In regular ways, the amount of glucose in the blood is measured by diagnosis of blood samples in a medical laboratory. Also there are products that measure blood glucose by pricking the fingers to draw drop of blood for glucose estimation. Both these ways are medically used for health care, which involves a invasive, painful way to measure blood glucose. This paper involves the design and implementation of a non-invasive technology based prototype for the measurement of blood glucose level along with Haemoglobin measurement. The prototype makes use of PhotoPlethysmoGraphy to achieve non-invasiveness, thereby overcoming the problems of prevailing medical devices. This prototype is implemented with low-cost sensors for providing economic viability. A Pilot study on volunteers to obtain results from the prototype. The results obtained from the prototype is analysed with the results from existing invasive product. Thus the paper defines the modelling a low-cost photoplethysmogrpahy based glucometer along with haemoglobin concentration measurement.
