Negative pressure wound therapy device. Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns.
Skin graft with vacuum-assisted wound closure after 5 days. STSGs are suitable for large wounds and relatively avascular sites where FTSGs would have a high risk of failure. Only a portion of the skin, namely the epidermis and part of the dermis, is removed from the donor site using a powered dermatome. [17]

The collection device is typically a bulb with a drainage port which can be opened to remove fluid or air. After compressing the bulb to remove fluid or air, negative pressure is created as the bulb returns to its normal shape. Blake drain - a round silicone tube with channels that carry fluid to a negative pressure collection device.
A vacuum unit then creates negative pressure, sealing the edges of the wound to the foam, and drawing out excess blood and fluids. This process typically helps to maintain cleanliness in the graft site, promotes the development of new blood vessels, and increases the chances of the graft successfully taking.
