A Non-contact Optical Device for Online Multiplexed Monitoring of Diseases of Military Importance in Fragile and Conflict-Affected Settings

Students of S.N.Bose National Centre for Basic Sciences, Probir Kumar Sarkar, Aniruddha Adhikari, Animesh Halder, Soumendra Singh won the award for developing a prototype of A Non-contact Optical Device for Online Multiplexed Monitoring of Diseases of Military Importance in Fragile and Conflict-Affected Settings. They carried their project work under guidance of Prof (Dr). Samir Kumar Pal .

Jaundice, Anaemia and Hypoxia, the three intimately interrelated health problems in military services particularly in fragile and conflict-affected settings take care of significant preventable casualties. These trio also proved to be the major cause for neonatal and maternal mortality in developing world. On the other hand, conventional gold-standard detection strategy through invasive blood sampling has several drawbacks for neonates and is redundant in fragile and conflict-affected settings. Thus a low cost and robust strategy for diagnosis of these diseases in all adverse conditions is of outmost importance to countries like India where huge number of military personnel are deployed in adverse geographical conditions along the border area and where under-5 mortality rate is alarmingly high. We, developed prototype of a noninvasive, non-contact, affordable, easy-to-use, point-of-care reflectance spectroscopy based device for measuring all three parameters at one go based on the spectral signature of bilirubin, hemoglobin and oxygen saturation from the vascular bed lying under conjunctiva (white portion) of eye. As conjunctiva is white independent of race, age or skin color, the device is useful to all. The indigenously developed software makes the device compatible to e-healthcare with possibility of online monitoring through cloud computing. Thus, this strategy will be extremely helpful in critical/low resource conditions like battle field and high altitude border regions for regular routine health check-up of army people who always devoted their life to protect the nation. The innovative noncontact, low-cost technique is expected to have importance in monitoring jaundice, anemia and hypoxia in developing / underdeveloped countries, where the inexpensive diagnosis with non-experts manpower is obligatory.

Dr. Harsh Vardhan, Minister of Science and Technology, awarded the Gandhian Young Technological Innovation (GYTI) Appreciation to Probir Kumar Sarkar, Aniruddha Adhikari, Animesh Halder, Soumendra Singh, S.N.Bose National Centre for Basic Sciences at the GYTI 2018 Awards function held at Rashtrapati Bhawan on March 19, 2018.
