In the COVID-19 crisis, if a worst case scenario is assumed, about 0.006 percent of the population will require critical care with access to ventilators. For a population of 125 Crores, this translates to about 75,000 patients who might need ventilator access.
In a large country like India, the biggest challenge is the manufacturing of such ventilators on a mass-scale due to limited access to pneumatic and electronic hardware, sensors and actuators in the global marketplace. The global supply chain has been severely disrupted due to the crisis, and there are no indications on when it will be restored. Hence, a group of Scientists and students in Indian Institute of Science in Bengaluru have developed an indigenous ventilator prototype.
AIR Correspondent reports, The Scientists and Students in Indian Institute of Science have developed a prototype of an indigenous ventilator under project Praana. The project is a voluntary effort to help the nation at the time of crisis. The team in the Electrical Communication Engineering Department of Indian Institute of Science, led by Associate Professor Gaurab Banerjee has designed the ventilator using materials readily available in India.
The prototype has mass flow sensors and controllers which accurately tell how much oxygen is flowing and what volume the patient is inhaling in one breath. Pneumatics is built around mass produced water filter hardware. The control system is built around open source industrial controller.
