Negative-Pressure Wound Therapy Dressings

Negative-pressure wound therapy (NPWT) is a therapeutic technique using a vacuum dressing to promote healing in acute or chronic wounds and enhance healing of first and second-degree burns. The therapy involves the controlled application of sub-atmospheric pressure to the local wound environment, using a special sealed wound dressing connected to a vacuum pump.

The system consists of a non-adherent, porous wound dressing such as foam, a draining tube placed in the dressing (or adjacent to it), and a transparent film to seal the wound and drainage tube that is connected to a vacuum source for negative pressure.

The key factor for Negative-pressure wound therapy is in the dressings, a tight seal around the wound bed is critical for success.  Fralock offers custom design capabilities and materials expertise for a variety of wound therapy applications.
