Healthcare innovation is an important topic. In 1928, an invention called an iron lung saved the life of an eight-year-old girl with polio. The cumbersome, coffin-like contraption, created by Harvard professor Dr Philip Drinker, used an electric motor connected to two vacuum cleaners. All but the head of the patient was placed inside an air-tight chamber, and through the huge bellows attached, the patient’s lungs were pumped and emptied of air until they could breathe again. This could take hours, days, or weeks.
