Tripura, 30th November: Adversity can often lead to innovation meet Ranjan Kumar Dhar a goldsmith in Tripura’s Jogendra Nagar Village who has devised a low-cost oxygen concentrator to help COVID19 patients.

The 38 years old’s inspiration for building the device came from his mother Kanika Dhar who tested positive for Covid 19 in September this year. The 62-year-old woman was discharged from GBP hospital in Agartala. She needed an oxygen concentrator to help her in recovery.

This was when her family learned that an oxygen concentrator costs Rs 650000 and renting an oxygen cylinder wasn’t cheap either it was Rs 1500 per day. I was always fond of trying things with electrical appliances. So I decided to try and make an oxygen concentrator.

He spent most of his time in a small room which he calls his innovation room trying to make things out of damaged materials by reading books, watching YouTube tutorials, and consulting with technicians and engineers.

I have used a few water bottles, a damaged water purifier, a humidifier bottle, a few exhaust fans, from a computer store, switches and circuit to device cost me one-third of the existing machines in the market. I want experts to test my device and see it fits the requirements and standard,” said Dhar.
