Reimagine wound care. One patient at a time.

The way you treat every patient is as unique as they are — and no two wounds, just like no two people, are exactly the same. With 3M’s scientifically engineered negative pressure wound therapy solutions and support, you can reimagine the way you approach wound care.

 

The 3M NPWT portfolio provides a wide range of wound management options, which have been shown in clinical studies to help reduce the cost of care and improve patient outcomes.1,2


How does NPWT work?

See the 3M™ V.A.C.® Therapy Mechanism of Action

3M V.A.C.® Therapy, one of the world leaders in negative pressure wound therapy, promotes an environment for wound healing by protecting the wound from external contamination, providing a moist wound environment, and promoting the formation of granulation tissue.3,4

 

The combination of a proprietary foam, drape, multi-lumen tubing, and advanced algorithms delivers a uniform negative pressure to the wound surface. This consistent negative pressure helps draw wound edges together, allows for the removal of exudate and infectious material, and stimulates the growth of tissue so the wound can heal.

    Draws wound edges together

    The application of uniform negative pressure induces a physical response — macrostrain — that can be seen immediately as the wound edges are drawn together, allowing for optimal contact between the wound bed and the dressing.

    Macrostrain facilitates removal of wound exudate which may contain inhibitors of wound healing.

    Reduces edema and promotes perfusion

    Removal of wound fluids assists in the reduction of edema, which facilitates the flow of blood into the wound bed, providing the oxygen and nutrients that are needed for wound healing.

    Promotes granulation tissue formation

    In vitro/in vivo studies show that foam contact with tissue creates micro-deformation that leads to cell stretch.3 Cell stretch under negative pressure stimulates cellular activity that results in granulation tissue formation.4-5

    Over subsequent dressing changes, the granulation tissue fills the wound bed, further reducing the volume, and preparing it for final closure.
