Balloon band aid

Balloon band aid works by applying pressure on children to stop bleeding after I.V. or blood collection. Parents used to physically press the puncture wound until bleeding stops. But it’s hard to control how much time and pressure parents should apply and meanwhile children are not allowed to move around freely. However, it contains a small air cell and after pressing the cell will inflate, applying pressure on the wound to staunch blood without the need of consistent pressing. It won’t hurt your body with a chemical reaction of edible citric acid and sodium bicarbonate inside the cell which produces water, carbon dioxide and sodium citrate.
