An adhesive, flat skin barrier product for use as semi-manufacture in the production of, a.o., dressings, wound-care devices, electrodes and fastening means for ostomy equipment and catheters, consists of alternating zones of material of at least two different kinds (26,28,30) at least one of which is a skinfriendly self-adhesive material. The zones are parallel and extend in a direction usually at right angles to the main surfaces of the product. The zones may for instance be parallel strips, co-axial rings, co-wound Archimedean spirals or short strands. The skin barrier product offers the advantage that in a simple way it may be produced to comprise, besides the sealing material itself, other components for special purposes, e.g. having contents of antiseptics, medicaments or others biologically active substances of liquid-transporting or electrically conductive structures.
In an adhesive, flat skin barrier product having a flat surface adapted to come into contact with the skin and an opposite flat surface, for use as a semimanufacture in the production of dressings, skin-and wound-care devices, electrodes for application to the skin, fastening means for dressings, ostomy equipment, wound drains and catheters, the improvement wherein said product consists of a plurality of alternating zones of at least two different kinds of material, at least one kind of material consisting of a substantially non-allergenic self-adhesive material, the zones of material extending substantially parallelly through the entire thickness of the product in a direction intersecting its flat surfaces wherein within a given zone the composition of said material is substantially uniform.
