Another use of defibrillator!!!
You might already knew that defibrillator is used by heart patients.
But a person from San Diego found that it can also save you in a different way.
Two men got into an argument about something. One person pulled a knife and stabbed the other in the chest.
Luckily, the knife hit the man's defibrillator, stopped the blade and saved the man's life.
So now you know the other use of defibrillator. It can sometime stop a knife attack!
