London, November 18 : Researchers at Wake Forest University, Winston-Salem, North Carolina, say that a novel electronic machine has been found to speed up the healing of wounds in pigs.
Lead researcher Louis Argenta has revealed that the flexible device forms a secure seal around a wound, and gradually pumps out air to lower the pressure, before gradually releasing the suction.
Lowering the pressure around the wound encourages the diffusion of oxygen from the blood into the damaged tissue.
This idea has been found to produce promising results in previous studies also, reports New Scientist magazine.
Argenta says that besides accelerating the movement of oxygen and other nutrients needed for healing into the wound, the fact this regularly distorts the healing tissue could contribute to the effect.
