Drawtex is a hydroconductive wound dressing with LevaFiber Technology. LevaFiber is a combination of two types of absorbent differentiated structures that creates the ability to draw exudate away from the wound surface. Drawtex tracheostomy and tube dressing is designed specifically for application around a tracheostomy tube after tracheostomy surgery. The keyhole aperture in the dressing allows it to fit neatly around a tracheostomy tube or other drain or stoma to collect fluid and exudates from the tracheostomy site that ultimately prevent peristomal maceration.
LevaFiber™ Technology Provides Three Different Types Of Action.
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 that defines the ability of a fluid to flow through porous media. Fluid can move from wetter to drier 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 charge at the surface of the Drawtex.
Wound bed preparation is the management of a wound in order to accelerate endogenous healing or to facilitate the effectiveness of other therapeutic measures. Recent data have been published showing how wound treatment with Drawtex assists with the complex challenges of wound bed preparation.
