What is the RENASYS EDGE System?

It is a negative pressure wound therapy (NPWT) system, which is a therapy device that is applied to your wound to draw out excess fluid and protect it from outside contaminants to ultimately help promote healing.1,2

How does the RENASYS EDGE System work?

The system consists of a device, a canister and a wound dressing kit. The dressing is placed on the wound and covered with a clear film. Once sealed, the dressing is attached to the device through tubing and a canister. The device then draws fluid from the wound into the canister.

How long will it take to improve my wound?

This is different for each patient and will depend on the size, type and location of your wound, as well as other treatments you may have been prescribed. Some patients see improvements within days, but for others it might take several weeks. Your nurse or doctor will decide when to stop your therapy or replace it with a different treatment.

Is the RENASYS EDGE Device painful?

You may experience a slight pulling or drawing sensation when the device is switched on, but it’s not usually painful. The level of discomfort can vary between patients. If you experience pain, speak to your nurse or doctor – they might need to adjust your device settings or prescribe pain relief medication.

How do I know the pump is working properly?

The green light will show you that the device is on and the pump is working properly.

How often does my dressing need to be changed?

This can be different for each patient, but will usually be 2-3 times per week. Your nurse or doctor will decide when dressings need to be changed.

Do dressing changes hurt?

Some people feel some discomfort, depending on the type and location of the wound (specifically during cleaning). If you feel discomfort, you should tell the healthcare professional changing your dressing.

Can I move around while using the system?

This will again depend on your wound, but you can usually move around as directed by your nurse or doctor using the carry bag and/or straps included. If you need to unplug the device, it can offer up to 24 hours of battery life on a full charge.3

What do the alarms mean?

The alarms indicate that there is an issue with the device. To address the alarms and continue your therapy, please check the troubleshooting guidance using the NFC feature and follow the on-screen instructions. If you are unsure, please speak to your nurse or doctor.

What is the NFC feature?

The Near Field Communication (NFC) feature is a Bluetooth interface. Using a smartphone or tablet device, place it over the NFC icon on the pump to access further help and information.
