Removal of exudate and oedema
Reduces the bacterial load and prevents maceration of the surrounding tissue.
Negative Pressure Wound Therapy (NPWT) is an advanced treatment to promote the healing of acute and chronic wounds through the controlled application of subatmospheric pressure within a closed system. It uses a special sponge or gauze placed on the wound, an airtight dressing and a vacuum pump that draws the exudate into a reservoir.
This technique creates a protected moist environment, reduces the risk of infection and improves exudate control, making it an effective tool for complex wounds, chronic ulcers, open surgical wounds and situations where tissue repair needs to be accelerated.
How does it work?
Improved blood perfusion
Increases the supply of oxygen and nutrients essential for tissue repair.
Mechanical microdeformation
Suction stimulates the formation of granulation tissue and angiogenesis.
Edge approximation
Negative pressure brings the wound edges closer together, helping it close progressively.
Main benefits
- Speeds up healing
- Reduces the risk of infection
- Makes it easier to manage heavy exudate
- Improves the quality of the tissue formed
- Greater patient comfort (fewer dressing changes)
Indications for the therapy
NPWT is especially indicated for complex wounds, chronic ulcers that are difficult to heal, open surgical wounds, traumatic wounds and situations where managing heavy exudate is a challenge. It is an option that provides greater patient comfort by reducing the frequency of dressing changes.
