Abstract
We have discovered a low trauma wound dressing including a moisture-vapor permeable backing and a contiguous particulate adhesive layer comprised of tacky, substantially solvent-insoluble, solvent-dispersible, acrylate-based, elastomeric, pressure-sensitive adhesive microspheres.
Claims44
A low trauma wound dressing having improved moisture vapor permeability comprising layers of (i) a moisture-vapor permeable backing, and (ii) a contiguous particulate adhesive layer of tacky, substantially solvent-insoluble, solvent-dispersible, acrylate-based, elastomeric, pressure-sensitive adhesive microspheres, wherein the adhesive layer further comprises an antimicrobial system effective for achieving a reduction in surface bacteria which includes at least an antimicrobial agent and a transfer agent.
A low trauma wound dressing having improved moisture vapor permeability comprising laminated layers of a moisture-vapor permeable backing and a multiple stratum adhesive layer of tacky, substantially solvent-insoluble, solvent-dispersible, acrylate-based, elastomeric, pressure-sensitive adhesive microspheres wherein at least an outermost stratum of the adhesive layers further comprises an antimicrobial system which includes at least an antimicrobial agent and a transfer agent.
A low trauma wound dressing having improved moisture vapor permeability comprising layers of (i) a moisture-vapor permeable backing, and (ii) a particulate adhesive layer containing at least (a) a major amount of a tacky, substantially solvent-insoluble, solvent-dispersible, acrylate-based, elastomeric, pressure-sensitive adhesive microspheres, (b) a minor amount of a binder, and (c) a combination of an antimicrobial agent and a transfer agent effective for achieving a reduction in surface bacteria.
