Drawtex™ wound dressings utilize a hydroconductive material to aid the clinician in wound bed preparation. It is a highly absorbent wound dressing that facilitates the movement of wound exudates into and through the dressing to the outer secondary material. The constant movement of wound fluids clears the wound bed of harmful wound byproducts that may slow down or prevent wound healing.
Drawtex™ uses what the manufacturing company, SteadMed Medical, LLC, calls LevaFiber™ Technology, based on the ability of the fiber construct to remove or lift wound debris, bacteria and harmful proteases into and through the dressing and away from the wound. This is accomplished by using a combination of capillary action, transpirational pull, and electrostatic attraction. These characteristics are what make the material hydroconductive and combine to make Drawtex™ unique from other fluid management dressings.
The capillary action mechanism is produced by small pores within the dressing acting as capillaries. Intermolecular attractive forces between the exudate and solid surfaces of the wound dressing allow the exudate to be drawn upward against gravity. The hydroconductive action of Drawtex™ allows the dressing to lift, hold and transfer the wound exudate both vertically and horizontally across the dressing. As the fluids reach the top surface of the dressing, evaporation enhances the pure capillary action increasing the fluid movement capacity to as much as 150cc per hour.1
The third property is electrostatic action. When the negatively charged dressing surface comes in contact with ions from fluids of an opposite charge, they bind to the dressing, effectively producing an electric double layer. This results in the surface having a net positive charge, thereby attracting the negatively charged bacteria and cytokines up into the dressing. The constant movement of fluid across the wound bed enhances autolytic debridement of necrotic material and the movement of the exudates up into the dressing.
Drawtex™ can be applied directly on the wound surface. When applied in multiple layers, the hydroconductivity of the dressing is enhanced allowing for the movement of high volumes of exudate per hour. It can to be changed daily, however, on healthy wound beds Drawtex™ can be left on for up to three days. It can be used on any wounds that wound be improved with the removal of excess exudate, improved autolytic debridement, and maintenance of a moist wound bed. Drawtex™ can be applied during all stages of wound healing and is one of our top products for cost effectiveness in the wound center.
