Pressure test
The effective “locking in” action of dressings with Hydrofiber® Technology is clearly demonstrated in this experiment. This is of particular relevance for dressings which are to be used in the treatment of venous leg ulcers, where compression is the mainstay of treatment.
Versiva® XCTM dressing incorporating Hydrofiber® Technology is saturated, simulating a dressing which has absorbed wound exudate, and placed under a 5kg weight (A 5kg weight was used to mimic the equivalent of 40mm Hg pressure).
After a specified time period, the weight is removed and we can see how the dressing containing Hydrofiber® Technology has not only retained all the absorbed fluid despite the pressure, but has prevented any lateral spread of fluid.
We can see that the two foam dressings, by comparison, have failed to retain the fluid.
