We have designed and developed a Negative Pressure Wound Therapy bandage, we call it, VacuAide. This bandage is the same size of regular adhesive bandages, but it has a miniature vacuum pump to induce a vacuum (negative pressure) on the wound.
To prevent air to be sucked into the wound, the adhesive bandage must be sealed with an airtight adhesive. A connection pad is then applied over a small hole that is made in the drape and is connected to a vacuum.
