In-vitro studies demonstrate that the Avelle™ NPWT System can manage fluid whilst distributing negative pressure through the dressing to the wound bed using a simulated wound model.
Total fluid handling demonstrated by the Avelle ™ NPWT Dressing
Effective fluid handling
The Avelle™ NPWT Dressing with Hydrofiber® Technology interacts with the wound bed by creating a moist wound healing environment whilst absorbing and locking in exudate 1 and the bacteria2,3 it contains.
In-vitro fluid handling studies demonstrate that:
PROVEN: The Avelle™ NPWT Dressing absorbed all test fluid whilst under 80 mmHg with no fluid pooling demonstrating optimal fluid management.
PROVEN: Effective fluid handling harnessing the mode of action of Hydrofiber® Technology.
Moderate exudate (82 ± 10mL) simulated wound bed after a 3-day period
Designed to manage low to moderate levels of exudate
Exudate is managed by the Avelle™ NPWT System via absorption and transpiration through the absorbent Hydrofiber® Technology layers and the breathable backing layer.
PROVEN: The absorption and moisture vapour transmission rate demonstrated by the Avelle ™ NPWT dressing works to facilitate a beneficial moist wound healing environment.
Delivery of negative pressure over 7 days through 4 layers of AQUACEL® Extra Dressing
Continuous delivery of negative pressure
The Avelle™ NPWT System is designed to produce a continuous negative pressure of 80mmHg (±20 mmHg) across the wound surface. In-vitro studies demonstrate4 that:
PROVEN: Negative pressure of 80mmHg (±20 mmHg) is delivered through the hydrated Hydrofiber ® Technology Dressing to the simulated wound bed through 4 layers of AQUACEL ® Extra Dressing to a depth of 2 cm over 7 days.
Maintenance of negative pressure (mmHg)
Maintenance of negative pressure
In-vitro testing demonstrates4 the one-way valve within the airway luer lock connector maintains pressure after removing the pump from the dressing after 1 hour ± 10 mmHg.
PROVEN: to deliver continuous negative pressure of 80mmHg (±20 mmHg) to the wound bed.
PROVEN: to maintain pressure upon disconnection from the pump for up to 1 hour.
Avelle NPWT System In-Vitro summary:
- PROVEN: continuous delivery of 80mmHg (±20 mmHg) through Hydrofiber® Technology in a gelled state.
- PROVEN: delivery of negative pressure when combined with AQUACEL® Extra filler dressing.
- PROVEN: effective fluid management in low to moderate exuding wounds.
- PROVEN: Avelle™ NPWT dressing -can maintain negative pressure for up to 1 hour when disconnected from the pump.
