Overview

The principles of negative pressure wound therapy

Negative pressure wound therapy (NPWT) delivers vacuum-assisted pressure below the wound surface to help promote healing. NPWT consists of a wound dressing (foam or gauze), a drainage tube, and a transparent film, sealed over the wound and connected to a suction device.

Modes Of Action »

Watch videos and learn how a negative pressure wound therapy device works with a foam or gauze interface to promote healing.

NPWT is particularly effective at:

  • Promoting granulation tissue formation
  • Restoring moisture balance
  • Improving perfusion
  •  
  •  
  •  

NPWT is indicated for patients with:

  • Pressure ulcers
  • Diabetic ulcers
  • Chronic, acute and traumatic wounds
  • Sub-acute and dehisced wounds
  • Skin grafts and flaps
  • Partial - thickness burns

NPWT is contraindicated for:

  • Untreated osteomyelitis
  • Presence of necrotic tissue with eschar
