New AI Diagnostics for Lung Diseases

AI and IoT based Diagnostic Device for Chronic Obstructive Pulmonary Diseases developed by IIT Kharagpur

Chronic Obstructive Pulmonary Disease (COPD) is a common chronic respiratory disease caused by exposure to harmful gases and particulate matters, with a high health burden on the country’s healthcare services and society. For long, the medical community has been depending on patient history and clinical symptoms for disease diagnosis, which often prevents early detection of the disease and advancing of the disease adds to the medical bill through frequent hospitalizations. 

Researchers at IIT Kharagpur have developed an affordable diagnostic intervention for Chronic Obstructive Pulmonary Disease based on the internet-of-things medical devices (IoT-MD) integrated with AI. [Download Journal Paper]

At the Organic Electronics Laboratory (ORELA), Department of Physics, IIT Kharagpur, Prof. Dipak Kumar Goswami and his research team have developed SenFlex.T, a smart mask synced with an android monitoring app through Bluetooth, that can continuously monitor breathing patterns, rate, heart rate, oxygen saturation level in blood. The app is connected to a cloud computing server, where artificial intelligence (AI) has been implemented to predict the severity of COPD through machine learning (ML). 

“SenFlex.T can be used at home by patients without having to visit diagnostic centres as against the current practice. This will also address the critical issue of addressing COPD at an early stage and by means of advanced healthcare technology, a boon for both patients and the overall healthcare system,” explained Prof. Goswami. 

Chronic Obstructive Pulmonary Disease has been a top cause of death, second to only deaths due to heart diseases. In 2017 it claimed about 1 million lives in India. In October 2019, health experts, at a medical convention, confirmed that COPD claims more lives than AIDS, TB, Malaria, Diabetes all put together. The threat from COPD has become more acute under the COVID situation, with increased comorbidity rates. A recent survey confirmed that the severity and mortality rates among COPD patients to be affected by the COVID-19 virus are over 63%. Moreover, the patients affected in the COVID-19 virus, which is right now over 4 million people in India and 27 million in the world, are more susceptible to build up various lung disorder-related diseases like COPD, Asthma etc. 

“It was crucial for health-tech researchers to develop a diagnostic intervention for Chronic Obstructive Pulmonary Disease. Spirometry, the gold standard test to diagnose obstructive airway diseases like asthma and COPD, is often avoided due to the unavailability of the equipment, difficulty in data interpretation and the cost of the tests. This challenge and the criticality strongly motivated us to develop an AI-based system, that can overcome the problem of interpreting the results and be accessible not only for the doctors but also for the patients,” said Prof. Goswami. 

SenFlex.T smart mask contains a highly sensitive, flexible temperature sensor along with a Bluetooth based measuring electronics. The sensor system can continuously monitor the temperature changes of inhaled and exhaled air during breathing and record the breathing pattern. The temperature sensor has a resolution of 4.3 mK and about 25 ms response time. Further, a commercially available pulse oximeter has been integrated with the sensor system to monitor the oxygen saturation level during breathing.

The patient data is uploaded automatically to the cloud server through the mobile app (SenFlex), where it is processed by means of AIML, and reports made available on the app and for doctors’ consultation. 

The innovation has been reported in the international journal ACS Applied Materials & Interfaces [Download Paper]. The researchers have also filed a patent for the innovation and are ready for commercialization. The product cost has been estimated at about ₹ 2,500/-.

Stepping-up Health Tech

IIT KGP and ICMR Collaboration for Mega Boost to Medical Technology Industry and Healthcare Ecosystem of India

IIT Kharagpur is going to set up a Centre of Excellence on Medical Device and Diagnostics to foster innovation of affordable and indigenous medical devices and diagnostics in priority areas and promote entrepreneurship. The proposal has recently been accepted for funding of ₹20 crore by Indian Council of Medical Research. 

In January 2020, ICMR had given a call for setting up a Centre of Excellence based on which IIT Kharagpur had proposed for the set up with thrust areas encompassing artificial intelligence in healthcare, medical devices for screening and diagnostics in healthcare, medical implants, biosensors in healthcare etc. 

“We thank ICMR, the apex body of Government of India spearheading biomedical research, for entrusting us with this responsibility. We look forward to working closely with ICMR and making meaningful contributions through these efforts. We had a rewarding experience in engaging with ICMR through a pilot ICMR – IIT Kharagpur MedTech internship program that drew great interest among engineering and medical students,” said Prof. V K Tewari, Director, IIT Kharagpur. 

India’s population size makes her healthcare challenges particularly the needs of the marginalized population in remote areas, unique, which require indigenous solutions. Accessibility and affordability have to be two key pillars of India’s medical technology development efforts. The coming together of ICMR and IIT Kharagpur is expected to give a big boost to already initiated R & D efforts at IIT Kharagpur that aim to lessen the burden of present pandemic. Further in the long run, this association will help the Institute achieve the goals set for the upcoming  Dr. B C Roy Institute of Medical Science & Research, a R & D driven super-speciality hospital followed by the first of its kind medical college in the IIT system. 

“Recently we heard that people residing in nearby areas of West Bengal and neighboring states of Jharkhand and Odisha are feeling hopeful that the burden of accessing healthcare facilities on patients and their families would be reduced with the upcoming superspecialty hospital of IIT Kharagpur. This can be taken further by catering to the need of a patient to visit a hospital through technology enabled healthcare at home and local level. The ICMR-IIT KGP Centre of Excellence will carry this responsibility forward with the much needed boost by bringing medical and technology domains together” said Director Tewari.

The centre will target to develop marketable technologies in a mission oriented time frame and use this experience to achieve longer-term goals to address challenging problems in the field of medical devices and diagnostics. Also, new intellectual property generation and a clearly defined licensing path will be the priority of the centre. Further the centre will try to extend medical technology related support to other organizations including different centres of ICMR.
