Abstract
A skin-friendly dressing which has a high moisture absorbing capacity, a high degree of flexibility and good integrity. The dressing includes a moisture-absorbing adhesive sheet to be adhered to the skin and mucous membranes, with a layer of water swellable colloid which is dispersed in or mixed with a water insoluble viscous elastomer binder and, if desired, usual auxiliary materials. The adhesive sheet at one outwardly directed surface is firmly connected to a non-adhesive water impervious cover layer, and at the other, against-the-skin or mucous-membrane directed surface of the adhesive sheet, a removable protecting sheet. The adhesive sheet is provided with one or several grooves or ditches that fully or partly surround a central part of the adhesive sheet.
