Actively manages edema and wound fluid by lifting, holding, and transferring fluid, debris, bacteria, and harmful MMPs away from the contact surface.1
Capillary action gives Drawtex its ability to move wound exudate and wound debris into the porous material of the dressing. With the small pores acting as capillaries, intermolecular attractive forces between the exudate and solid surfaces of the wound dressing allow the exudate to be drawn upward against the force of gravity.
Hydroconductive action is controlled by Darcy’s Law, which defines the ability of a fluid to flow through porous media. Fluid can move from wetter to drier zones, even against gravity. This explains how water can be transported from the roots of a tree to the leaves. The LevaFiber™ Technology of Drawtex allows the dressing to lift, hold, and transfer the wound exudate both vertically and horizontally by hydroconductive action.
Electrostatic action results in attraction of negatively charged bacteria and cytokines (MMPs) to the positive charged zones at the surface of the Drawtex.
