UPDATED: May 11, 2021 10:02 IST Mohammad Ismail Mir with the low-cost oxygen concentrator prototype he signed at home in Kashmir (Photo: India Today) At a time when the country is grappling with a crisis of oxygen equipment, 60-year-old Mohammad Ismail Mir has made an affordable prototype of an oxygen concentrator at home. His penchant for scientific innovation has earned him the title of 'Newton' among the locals. “It took me around 20 days to make this prototype. It functions just like any other oxygen concentrator. It automatically provides oxygen and removes blockages if they are formed in it,” Mohammad Ismail said. When asked about the number of people the prototype will be able to support, he said, “It will depend on the kind of compressor and filter we use. For one person we will use small ones and for more patients, the parts will have to be accordingly modified,” he said.
