A sheet-form material suitable as wound dressing and having enhanced moisture control properties is disclosed. This sheet-form material includes a porous sheet of absorbent, elastomeric segmented polyurethane having an open pore structure and an apertured adhesive facing on one side of the porous sheet. A liquid impermeable but water vapor permeable backing may be provided on the opposite side of the porous sheet, if desired. Also disclosed is a method for forming an apertured adhesive facing for the sheet-form material.
A sheet-form material suitable as a wound dressing which comprises a porous sheet of absorbent, elastomeric, polyurethane having an open pore structure and defining macropores at one surface of said sheet, and an adhesive wound facing layer on said sheet contiguous with said macroporecontaining surf
A sheet-form material suitable as a wound dressing which comprises a porous sheet of absorbent, elastomeric, polyurethane having an open pore structure and defining macropores at one surface of said sheet, and an adhesive wound facing layer on said sheet contiguous with said macroporecontaining surface and defining apertures that communicate with said macropores and provide fluid channels thereto; said porous sheet being a segmented polyurethane having a pore size gradient across the thickness dimension thereof and with the pore size decreasing in the direction away from the macropore-containing surface.
