That's a very interesting device! I was not familiar with this concept of suction speeding up healing. A device this simple and inexpensive seems like it would be a boon to those who have stubborn wounds that just don't heal. It would be great to have a widely available method to promote wound healing without having to resort to administering ever more powerful--and ever more precious--antibiotics, to surgery, or to medications which have their own list of possible side effects.
