Negative Pressure Wound Therapy Device: Negative pressure wound therapy (NPWT) is a method of drawing out fluid and infection from a wound to help it heal. A special dressing (bandage) is sealed over the wound and a gentle vacuum pump is attached. Modern NPWT systems consisting of an open pore foam sponge, adhesive dressing and a vacuum pump producing negative pressure have been used as an adjunct to surgical debridement to treat tissue defects around open fractures and chronic, contaminated wounds. Other uses include supporting skin grafts and protecting wounds at risk of breaking down.
