Non-Invasive Glucose Estimation Using IR Spectroscopy

Diabetes milletus is disquieting human lives. The key health issues such as cardiovascular diseases, damage of blood vessels, stroke, blindness, chronic kidney damage, nervous system diseases, amputation of foot due to ulceration and early deaths are caused by poor management of diabetes . The reason behind all these are negligence in continuous monitoring. Regular monitoring of blood glucose is important to avoid complication of diabetes. Commonly used glucose measurement means are offensive which generally involves finger puncturing. These methods are painful and frequent pricking cause lumps on the skin and have risk of spreading infectious diseases. Therefore there is need to develop a non-invasive nursing system which can measure blood glucose continuously without much problem. The present work is focused on evolution of non-invasive blood glucose measurement sensor system using Near-infrared technique. Later a Sensor patch was designed using LED and a photo diode to observe diffused reflectance spectra of blood from the human forearm. Diffused reflectance spectra of the patients obtained with this technique was also compared with commercially available invasive glucose-meter. The results are hopeful and show the potential of using NIR for glucose measurement.we use sensor to monitor the blood glucose level of the patient. When it is High Level Glucose, Insulin will be injected through a syringe from Servo Motor Side. High rise of glucose level may lead to heart attack or any difficulty situations so we use via SMACServer Updating the patient Condition easily for identification in the PC Unit. In case of any abnormal situation we use motor to automatically inject the medicine into the patient using the syringe.
