Frequently Asked Questions

How long do I keep 3M™ Prevena™ Therapy on my incision?
Wear the system for as long as your doctor has ordered, at which time the dressing will be removed by your doctor.
Will my incision dressing need to be changed?

Where should I keep my Prevena Therapy Unit?
Keep your therapy unit in a safe place where tubing will not become kinked or pinched, and it cannot be pulled off a table or dropped onto the floor.
Do I need batteries for my Prevena Therapy Unit?
This therapy unit has a rechargeable battery and comes with a charger. Bring your charger with you if you are gone for extended periods of time. For convenience, consider charging your therapy unit battery while you are sleeping.

The 3M™ Prevena™ Incision Management System is intended to manage the environment of closed surgical incisions and surrounding intact skin in patients at risk for developing post-operative complications, such as infection, by maintaining a closed environment via the application of a negative pressure wound therapy system to the incision. The 3M™ Prevena™ Incision Dressing skin interface layer with silver reduces microbial colonization in the fabric.
