GROWTH STIMULATING WOUND DRESSING WITH IMPROVED CONTACT SURFACES

摘要

A wound contact device comprising a permeable material and a wound contac t 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 fil m forming a generally flat and smooth wound contact surface having essential ly no discontinuities or gaps. The wound contact layer can comprise a thin s heet of highly calendered fabric forming a wound contact surface having a me an surface roughness in the range of about O microns to about 200 microns. I n progressive wound healing, an embodiment of the wound contact device havin g the fabric contact surface is used in earlier healing stages and an embodi ment of the wound contact device with film contact surface is used in later healing stages. The wound contact device is particularly useful in wound dre ssings for use in suction-assisted wound therapy.
