Spray on bandages

  In the year 2014 there was a new big break in medical products. It was called the spray on bandage. Do you remember bandages were sticky and it was teeth gritting when you had to rip them off. Well this invention made it possible to forget that. Created in South Korea and Germany, it helped the doctors keep track of the wounds and know the healing process of the cut. 

  When wounds heal they need extra glucose and oxygen. Without these compounds it would leave behind painful sores. Thankfully they created a spray on bandage to monitor the healing. It still allowed the compounds to get in.  This bandage was created before 2014, but it was to expensive so it could not be finished. Eventually it was finished and it has been a huge improvement to humanity.
