The history of Negative Pressure Wound Therapy (NPWT)


Watch the video below to see how NPWT got started, how it affects wound care today and how it will change wound care in the future.


The principles of NPWT


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 or port inserted into the dressing and a transparent film that is connected to a suction device.


See how NPWT works in the mechanism of action video below.
