MCHENRY, Ill. – Medela's Invia Liberty negative pressure wound therapy system is able to re-establish the prescribed pressure, while simultaneously clearing 89% of the fluid in less than 20 minutes, the manufacturer said in a peer-reviewed study published in a supplement to Wounds. Due to Invia's ability to remove exudate more efficiently and re-establish a patent system, it was also able to return the wound to the prescribed pressure more quickly and maintain the set pressure at the wound site more effectively. "The data demonstrates how important it is that NPWT systems are able to dynamically sense and respond to fluid volumes and viscosities as wound conditions change," said Rey Paglinawan, medical research manager for Medela. "Delivering set pressure to the wound bed and maintaining tubing that is patent and clear of fluid is essential for leveraging the full benefits of NPWT, critical for successful wound healing. This can only be realized with a proven and reliable system." Chronic wounds, including pressure injuries, diabetic foot ulcers and burns, cost an estimated $28 billion per year, according to Medela.
