Dressing selection
When selecting the Avelle™ NPWT dressing consider the following:
- The port should be positioned uppermost over intact skin.
- Ensure the wound area is no more than 25% of the pad area and there is a 1cm overlap of the pad on to peri-wound skin.
- The wound or incision should be positioned 1cm away from the silicone border
- The wound or incision should be positioned 1cm away from the port which covers a 5cm area of the dressing pad.
For closed incision applications consider the following guidance in order to select the appropriate dressing size:
| Dressing Size | Outer Pad Size | Inner pad size | For incisions up to: |
|---|---|---|---|
| 12 x 21cm | 6 x 15cm | 4 x 13cm | 6cm / 2.4in |
| 12 x 31cm | 6 x 25cm | 4 x 23cm | 16cm / 6.3in |
| 12 x 41cm | 6 x 35cm | 4 x 33cm | 26cm / 10.2in |
Finding a seal
Establishing an effective seal around the dressing and peri-wound skin is critical to ensure delivery of therapy. Application of negative pressure to difficult to dress anatomical locations along with patient factors such as perspiration, mobilisation and showering can lead to challenges in maintaining a long-lasting air-tight seal. That’s why we provide a range of accessory products which can be used to assist the seal for NPWT in challenging to dress areas:
- ConvaTec™Hydrocolloid Sealing Strips
Thin, flexible and designed to assist in creating the optimal seal to ensure your patients receive effective NPWT. - Sensi-Care® Sting Free Barrier
A 100% silicone based sting-free skin barrier which creates a breathable barrier to protect the skin from damage caused by adhesives. - Sensi-Care® Sting Free Releaser
A 100% silicone based spray to assist with the gentle removal of adhesives applied to the skin.

FAQs
What is the Avelle™ NPWT System?
The Avelle™ Negative Pressure Wound Therapy (NPWT) System consists of a non-sterile pump, a sterile wound dressing, fixation strips and batteries. The pump is a disposable unit that may be used for up to 30 days* as a single patient use device. The dressing may be left in place for up to 7 days. A nominal negative pressure of 80mmHg is maintained at the wound surface by the Avelle ™ NPWT Pump. Wound exudate is managed by the dressing through the absorption and gelling capability of Hydrofiber® Technology and via moisture evaporation at the dressing outer surface.
What are the indications for use?
The Avelle™ NPWT System is suitable for wounds with low to moderate levels of exudate, including:
- Chronic wounds (e.g. ulcers)
- Acute wounds, such as:
- Traumatic
- Dehisced wounds
- Flaps and grafts
- Surgically closed incision sites
How does the Avelle™ NPWT System work?
The Avelle™ NPWT Pump works to produce a nominal negative pressure of 80mmHg(±20 mmHg) which is maintained at the wound surface. Wound exudate is absorbed and managed by the dressing through the gelling capability of the Hydrofiber® wound contact layer and the Hydrofiber ® Technology layers. The strengthened (stitch-bonded) Hydrofiber ® Technology wound contact layer is designed to help maintain dressing integrity on removal1, Channels in the dressing structure are designed to allow fluid to move throughout the dressing ensuring exudate is locked away in the Hydrofiber ® Technology layers1, The foam layer aids distribution of negative pressure across the dressing and to the wound bed1, whilst the backing film permits evaporation of exudate aiding overall fluid handling. The silicone adhesive border is designed to be gentle to the skin upon removal1,2.
What is the battery life of the Avelle™ NPWT System?
The Avelle™ NPWT System is supplied with two sets of x3 AAA Phillips ™ Lithium Ultra FR03 Lithium batteries. The battery life during therapy will be dependent on how many times the pump is required to re-establish the correct level of pressure at the wound bed. Battery lifetime is affected by the quality of the dressing seal and the connection of the dressing to the pump. The Avelle ™ NPWT Pump will last for up to 30 days of therapy however battery changes will need to be made during this period.
What is the recommended wear time of the Avelle™ NPWT Dressing?
The dressing should be changed in accordance with the IFU or as clinically indicated. A typical wear time is 3-4 days up to a maximum wear time of 7 days. Depending on wound exudate level or other clinical indicators, a more frequent dressing change may be required. The dressing should also be changed if there are signs of leakage, pooling around the port, or loss of adhesion.
What dressings sizes are available within the Avelle ™ NPWT range?
Avelle NPWT dressings are available in a range of sizes including: 16x16cm, 16x21cm, 12x21cm, 12x31cm, 12x41cm, 21x26cm and 26cm x 26cm. See the Accessories and Ordering page for further details.
