A new medical invention called the "smart syringe" could keep thousands of people from becoming infected from dirty syringes.
Special ink inside turns red when the syringe is exposed to carbon dioxide in the air alerting doctors that the syringe may have already been used.
The design could save millions of lives.
The World Health Organization estimates more than a million people die each year from unsafe injection practices.
