The doctor who turned a shampoo bottle into a low-cost lifesaver

Around 920,000 babies and small children die from pneumonia each year. Bangladeshi doctor, Mohammod Jobayer Chisti, has invented a device to help them survive using a shampoo bottle and some plastic tubing.

After two decades of research, Dr Chisti's device - which costs just $1.25 (£1) - has already saved hundreds of young lives.
