New Data on Physical Performance Characteristics of Negative Pressure Wound Therapy Dressings
ConvaTec announces new in vitro study results. The Engenex® Negative Pressure Wound Therapy (NPWT) systems Bio-Dome wound interface showed superior tensile strength and lower simulated bioadhesion when compared with GranuFoam (polyurethane foam). This study was conducted by employees of ConvaTecs Global Development Center and was presented at the annual Fall Symposium on Advanced Wound Care in Anaheim, Calif.
In addition to the superior tensile strength and lower simulated bioadhesion, the laboratory tests also showed that the Bio-Dome wound interface provided broader contours of microstrain when compared to GranuFoam. The Bio-Dome wound interface also effectively transmitted sufficient levels of fluid to the canister from simulated highly exuding wounds.
To better understand the physical performance attributes of wound interfaces, a range of in vitro physical testing and analytic studies using different levels of applied negative pressure were performed.
The analytic studies included finite element analysis (FEA) to predict strain forces applied to the wound bed; fluid handling testing to simulate exudate management capabilities; tensile strength of interface dressings to show their robustness during handling; and simulated bioadhesion testing.
The Engenex® Negative Pressure Wound Therapy System is an innovative technology and engineering solution that utilizes the application of negative pressure to a wound to promote healing and to remove excess fluid, including wound exudate.
