Avelle™ NPWT System

Hydrofiber divider

Effective fluid handling

The Avelle™ NPWT Dressing with proprietary Hydrofiber®
Technology interacts with the wound bed by creating a moist
wound healing environment whilst absorbing and locking in
exudate1 and the bacteria2,3 it contains.


In-vitro fluid handling studies demonstrate4 that:

  • The Avelle™ NPWT Dressing absorbed all test fluid
    whilst under 80 mmHg with no fluid pooling demonstrating
    optimal fluid management.
  • Effective fluid handling harnessing the mode of action
    of Hydrofiber® Technology.

Continuous delivery
of negative pressure


The Avelle™ NPWT System is design to produce a continuous negative pressure of 80 mmHg (±20 mmHg) across the wound surface. In-vitro studies demonstrate4 that:

  • PROVEN: Negative pressure 80 mmHg (±20 mmHg) delivered through the hydrated Hydrofiber® Technology
    Dressing to the simulated wound bed through 4 layers of AQUACEL® Extra Dressing to a depth of 2cm over 7 days.

  • PROVEN: to deliver continuous negative pressure of 80 mmHg (±20 mmHg) to the wound bed.
  • PROVEN: to maintain pressure upon disconnection from pump for up to 1 hour.
