Abstract

A conformable wound dressing comprising a layered combination of: a moisture vapour permeable backing layer with a moisture vapour permeability of less than 600 g m -2 24hr -1 when measured at 37.5{C and 100 % to 10 % relative humidity difference, a wound facing discontinuous layer adapted to adhere to the skin and having an uninterrupted moisture vapour permeability of at least 300 g m -2 24hr -1 when measured at 37.5{C and 100 % to 10 % relative humidity difference and an absorbent layer intermediate the backing and wound facing layer or a combination of: a moisture vapour permeable backing layer with a moisture vapour permeability of at least 600 g m -2 24hr -1 when measured at 37.5{C and 100 % to 10 % relative humidity difference, a wound facing discontinuous layer adapted to adhere to the skin and having an uninterrupted moisture vapour permeability of less than 300 g m -2 24hr -1 when measured at 37.5{C and 100 % to 10 % relative humidity difference and an absorbent layer intermediate the backing and wound facing layer.
