NPWT - Mechanism of Action8-9


  • Reduction in tissue oedema
  • Wound contraction via applied strain
  • Increased perfusion
  • Stimulation of angiogenesis
  • Formation of granulation tissue

1. Perforated silicone adhesive borders
Specifically designed to secure the dressing in place while being gentle to the skin during

2. Hydrofiber® Technology wound contact layer
Stitch-bonded Hydrofiber® wound contact layer gels on contact with wound fluid and is
designed to maintain integrity on removal.11

3. Hydrofiber® Technology (8 layers)
Gel on contact with wound fluid and locks in bacteria within it.11,12* Fenestrations in the
Hydrofiber® Technology layers are designed to promote vertical fluid movement throughout the dressing.

4. Foam layer
 Aids distribution of negative pressure across the dressing and to the wound bed.

5. Soft port
Designed to minimise the risk of pressure damage.

6. Film layer
The backing film permits evaporation of exudate, aiding overall fluid handling while
providing a bacterial, viral and showerproof barrier.11
