About NPWT – Rayvac

What it is

NPWT (often called a “wound VAC”) uses a small pump and a sealed dressing to create gentle suction. This removes extra fluid, protects the wound, and encourages healthy new tissue.

Why it helps

May speed healing and reduce swelling
Keeps the wound clean by removing fluid into a canister
Protects under an air-tight film
Can reduce dressing changes and discomfort
Supports skin grafts and flaps

How NPWT works

A foam dressing is placed in or over the wound.
A clear film seals the area so it’s air-tight.
A small pump connects by tubing and applies a gentle, controlled vacuum.
The pump pulls fluid into a canister and keeps the wound environment clean and protected.
Think of it like this: a tidy, sealed “mini-healing chamber” that quietly removes what slows healing (fluid, swelling) and supports what helps healing (healthy blood flow and tissue growth).

Step 1 — wound cleaned and measured before NPWT — Step 1 — Prepare and clean the wound.
