From New Scientist:Medics are constantly on the lookout for ways to speed up the healing of wounds. One idea that has produced promising results is to lower the pressure around the wound to encourage the diffusion of oxygen from the blood into the damaged tissue.
Louis Argenta at Wake Forest University, Winston-Salem, North Carolina, says that this process can be accelerated further by rhythmically sucking and then releasing the pressure on the wound.
Injuries caused by accidents, disease, burns or surgery can all be helped, he claims.
The flexible device forms a secure seal around a wound and gradually pumps out air to lower the pressure, before gradually releasing the suction. It can even then apply increased pressure to a wound, which may help as part of the treatment.
