NPWT

Negative Pressure Wound Therapy (NPWT) is a therapeutic non-invasive technique by using vacuum source to promote acute or chronic wound healing and fight infection.


NPWT consist of a wound dressing (gauze or foam), a drainage tube, an occlusive transparent film dressing, and is connected to a vacuum source that supplies negative (subatmospheric) pressure. It's used for the clinical treatment of many wound types, including orthopaedic trauma, soft tissue trauma, skin grafts, pressure ulcers, venous leg ulcers, diabetic foot ulcers, burns, surgical infections, and management of other major surgical wounds.


As one of the  NPWT manufacturers, Winner could provide you disposable NPWT devices and NPWT dressing kit. Please contact us if you need them.

NPWT FAQs

  • Q.
  • What is NPWT?
  • A.
  • NPWT uses a closed drainage system to apply controlled suction (vacuum) to a wound bed. The wound is first filled with a wound filler (gauze or foam) to allow pressure to be distributed evenly to the wound bed. The wound is then sealed with an adhesive plastic film and the drain is connected to a vacuum pump. Wound fluid is sucked out through the drain and collected in a canister.

  • Q.
  • Why use negative pressure wound therapy?
  • A.
  • The data show that NPWT provides excellent clinical benefits and significantly reduces the cost of wound care. NPWT creates a moist environment, drains exudate, reduces tissue oedema, contracts the wound edges, mechanically stimulates the wound bed, alters blood flow in the wound edges and stimulates angiogenesis and the formation of granulation tissue. NPWT can offer protection against infection as the wound is sealed. In addition, the need for less frequent dressing changes may further reduce the risk of contamination.


  • Q.
  • When to use NPWT system?
  • A.
  • The NPWT system is indicated for patients with orthopaedic trauma, soft tissue trauma, skin grafts, pressure ulcers, venous leg ulcers, diabetic footulcers, burns, surgical infections, and management of other major surgical wounds.

  • Q.
  • What are contraindications?
  • A.
  • Untreated osteomyelitis

    Exposed arteries, veins, organs or nerves

    Necrotic tissue with eschar present

    Malignancy in wound (with exception of palliative care to enhance quality of life)

    Non-enteric and unexplored fistulas

    Anastomic sites

    Bleeding tendency

  • Q.
  • How does negative pressure wound therapy work and what is the benefit?
  • A.
  • The negative pressure wound therapy adopts sterile dressing with good air permeability, which promotes the growth of granulation and can cover the surface of the wound completely. After sealing the wound, a suction device is used to attract the surface of the dressing continuously, so as to achieve the following effects and benefits: promote the falling off of wound secretion or rotten ulcer tissue to avoid their long-term existence affecting the healing process or causing unnecessary infection; prevent bacterial infection effectively, as most bacteria can not survive under the negative pressure.

  • Q.
  • What type of wound is not suitable for negative pressure wound therapy?
  • A.
  • It is of great importance to know the wound type that is not suitable for negative pressure wound therapy. For exposed wounds like exposed blood vessels, arteries, organs and nerves, NPWT therapeutic non-invasive technique should be avoided. Besides, you should never employ this therapy for the treatment of untreated osteomyelitis, necrotic tissue with eschar, non-enteric and unexplored fistulas. NPWT is also unsuitable for anastomotic sites and malignancy in wound.
