New Delhi: Defence Research and Development Organisation (DRDO) has been tracking the spread of Coronavirus (COVID-19) since the world media started reporting its devastating impact in China’s Wuhan Province. The DRDO took a call in first week of March 2020 to enhance efforts to create counter measures to stop the spread of the disease in India. By then, the number of affected people in India had already crossed 30. It also started focusing on creating mass supply solutions of critical medical requirements, if COVID-19 becomes a crisis. As a result of focused approach, at present DRDO is ready with four different items ready to be deployed in ‘War against Corona’.

Total capacity is 20,000 to 30,000 litres per day in 200-500 ml bottles. The cost is less than Rs 120/litre (including GST).

Ventilators

Since COVID-19 affects pulmonary functions, keeping in mind the futuristic requirement, Society for Biomedical Technology (SBMT) programme of DRDO has been modified to cater to the current situation. Defence Bio-Engineering & Electro Medical Laboratory (DEBEL), Bangalore (a DRDO lab) has identified a vendor (M/s Scanray Tech Pvt Ltd, Mysore) to produce critical care ventilator. It has been created by using existing technologies like breath regulators, pressure/flow sensors, etc. Presently, innovation is on to create ‘Multi patient ventilator’ wherein several patient can be supported by a single ventilator. This innovation is expected to be available within a week. Around 5,000 ventilators will be produces in the first month and 10,000 subsequently. The DRDO has identified local alternatives to supply of critical components. Already Secretary (Pharmaceuticals) has identified nine companies for design transfer to produce and Mr Anand Mahindra for fabrication of components. Each ventilator unit will cost around Rs four lakh.

N99 masks

Five layer N99 masks with two layers of nano mesh are very advanced. These are one of the critical times to stop spread of Corona. Its production vendors are M/s Venus Industries Mumbai, M/s IMTEC Kolkata. Capacity is 10,000 N99 masks per day.
