Abstract:
A method of manufacturing a laminated dressing that includes providing a lower layer having a fiber material that directly contacts a patient's skin and a wound area, providing an upper layer that has a foam or foam-like material that absorbs exudate and moisture, and binding the fiber-based lower layer and the foam-based upper layer with a binder layer comprising a binder material, the binder layer including a series of perforations. The perforations in the binder layer are formed by removing material from the binder layer with a pattern coated adhesive sheet prior to binding the fiber-based lower layer and the foam-based upper layer.
