A wound contact device comprising a permeable material and a wound contact layer having voids extending through the contact layer to a depth in the permeable material. The wound contact layer can comprise a thin sheet or film forming a generally flat and smooth wound contact surface having essentially no discontinuities or gaps. The wound contact layer can comprise a thin sheet of highly calendered fabric forming a wound contact surface having a mean surface roughness in the range of about 0 microns to about 200 microns. In progressive wound healing, an embodiment of the wound contact device having the fabric contact surface is used in earlier healing stages and an embodiment of the wound contact device with film contact surface is used in later healing stages. The wound contact device is particularly useful in wound dressings for use in suction-assisted wound therapy.
A wound contact device for use in treating a wound with suction, the wound contact device comprising a permeable material and a wound contact layer on the permeable material, the wound contact layer comprising a thin film forming a wound contact surface, the wound contact device having a plurality of voids extending through the contact layer to a depth in the permeable material and defining wound contact elements on the wound contact surface.
A wound contact device for use in treating a wound with suction, the wound contact device comprising a permeable material and a wound contact layer on the permeable material, the contact layer comprising a thin sheet of non-woven fabric forming a wound contact surface, the wound contact device having a plurality of voids extending through the contact layer to a depth in the permeable material and defining wound contact elements on the wound contact surface.
A wound dressing for use in treating a wound with suction, the wound dressing comprising interconnected interstices for transporting fluids away from the wound and a wound contact surface have a plurality of voids extending to a depth in the wound dressing, the wound dressing having sufficient compression resistance to maintain empty space in the voids under the compressive force of therapeutic suction to facilitate tissue growth into the void spaces.
A method of treating a wound with suction using a wound contact device, the wound contact device comprising a permeable material and a wound contact surface, the wound contact device having a plurality of voids extending through the contact layer to a depth in the permeable material and defining wound contact elements on the wound contact surface, the method comprising:
