VAC / NPWT

Negative pressure wound therapy (NPWT), also called vacuum-assisted wound closure, refers to wound dressing systems that continuously or intermittently apply subatmospheric pressure to the system, which provides a positive pressure to the surface of a wound. NPWT has become a popular treatment modality for the management of many acute and chronic wounds.

Vacuum-assisted closure of a wound is a type of therapy to help wounds heal. It's also known as wound VAC. During the treatment, a device decreases air pressure on the wound.
