Test Results for EverLift RemovEZ Hydrocolloid Skin Removal Force Study
In 2004 an outside consultant, Medical Device Designs Incorporated of Madeira Beach, Florida was engaged to quantitatively evaluate Xennovate Medical’s design concept for reducing the removal force of a hydrocolloid, while concurrently minimizing the loss of adhesive force.

This consultant employed a study model developed by him while at Pfizer United two decades earlier. His model employs the forearm of test subjects, and he has often demonstrated the value of using live skin over stainless steel, the so-called “standard” stainless steel test. In this expert's opinion the stainless steel test does not effectively evaluate the adhesion effects on live skin.
Finally, our shear force formulation, xm18s, has been demonstrated to be extraordinary. The strength of our product in this category enables it to remain in place on the patient without accidentally being removed while sleeping, for example. EverLift RemovEZ + PULL-TAB provides an amazing adjunctive component for specialty adhesion applications.
The bottom line result was a new patent surrounding the application of an apertured-opening, generally referred to as a "scrim" by manufacturing converters, to the skin side of an adhesive layer, reduces removal forces by over 30% for a wound dressing that is 25-30 mils [0.635 mm) thick. Adhesive force reduction due to the addition of the scrim was less than 2%.
