摘要:
A laminated wound dressing 10 comprises a lower layer 20 which directly contacts the skin and which comprises a fibre material, such as a non-woven spunlaced polymer fabric or polyethylene. The dressing 10 also has an upper layer 30 of a foam or foam like material, such as polyurethane, to absorb exudate and moisture. A middle binder layer 40 is disposed between these two layers, to bind them together. The binder layer 40 comprises a binder material and has a number of perforations 44. Preferably, the binder layer 40 is fabricated from a polyester or polyamide material. Also disclosed is a method of fabricating a binder layer for a laminated dressing. A binder layer is brought into contact with a pattern coated adhesive sheet and a series of closed loop cuts are made in the binder layer. The binder layer is then moved away from the adhesive sheet so that they are no longer in contact, such that the material enclosed in the closed loop cuts is retained on the adhesive sheet and the binder layer has series of cleared perforations.
