In India, about 15 babies die every minute due to asphyxiation in maternity homes that can’t afford the costly imported infant warmers. Many midwives try and make do with table lamps — but they are a poor substitute. As a student of IIT Chennai in 1988, Sashi Kumar was asked to repair imported baby warmers for a hospital. Kumar, 49, not only fixed the warmers but also started making them on his own — his company Phoenix Medical Systems was born.
