Abstract: Dressing material of at least one layer of a polymeric, hydrophilic gel and, where relevant, one or more layers of a carrier material as an intermediate and/or covering layer, wherein the gel consists of 40-50% by weight of a polyvinyl alcohol which is crosslinked and acetalized with formaldehyde and is water-insoluble to the extent of at least 90%, 15-30% by weight of water, 15-45% by weight of one or more polyhydric alcohols with 2-6 C atoms and, where relevant, small amounts of additives and/or auxiliaries.

Abstract: A visco-elastic gel comprising a high molecular weight polysaccharide, at least one polyol and, optionally, at least one non-volatile acid soluble in the polyol and at least one non-volatile base soluble in the polyol. The polyol has a water content of 5 to 20 percent by weight and the various components set forth are physiologically acceptable. The gel is particularly suitable as a means for releasably securing an electrode to the skin as, for example, when taking an EEG or EKG. Methods of making a suitable electrode and using it are also disclosed.
