Abstract
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.
