The 3M Prevena™ 125 Therapy Unit is a medical device designed for incision therapy, utilizing negative pressure wound therapy (NPWT) to manage surgical incisions. It is a portable unit that provides continuous therapy and features various indicators and alerts to ensure proper operation and patient safety.

Function Description

The primary function of the Prevena 125 Therapy Unit is to apply negative pressure to surgical incisions, which is believed to help reduce edema, improve perfusion, and promote healing. The device creates a sealed environment over the incision using a specialized dressing, and then applies controlled negative pressure to the area.

Usage Features

Ease of Application: The device is designed for use with 3M Prevena Incision Dressings. The Visicheck™ Feature guides users in achieving an optimal seal.
