Abstract: The invention relates to an indicator dressing with a carrier element, which is, at least in regions, provided with a marker material, which material, in a specific microbial contamination, changes a color. According to the invention, a first marker material is provided, which, in a first specific microbial contamination, changes color, and at least one second marker material is provided which changes color in a second specific microbial contamination, which material differs from the first microbial contamination. The invention moreover includes a method for indicating a contamination with this indicator dressing.

Abstract: The invention relates to a dressing arrangement and to a method for treating a wound of a human or animal body by means of vacuum. The dressing arrangement has an absorbent body for absorbing wound secretions, the absorbent body being designed for insertion in a cavity of the wound. Furthermore, a separating element is provided, which is arranged between the wound and the absorbent body. Furthermore, a cover element, which is designed to cover the wound, together with the absorbent body, in a substantially airtight manner, and a connecting means are provided, which connecting means is arranged for connecting a vacuum source to the cover element. According to the invention, it is provided that the separating element is designed to be larger than the wound to be treated, a protruding edge portion being formed, and that the edge portion is attached to a skin region at the edge of the wound.

Abstract: The invention relates to a wound dressing and a method for producing a wound dressing with a marker material for indicating a condition of a wound, in particular a microbiological wound milieus. The invention is characterized in that the wound dressing has a contact side which is formed by a biocompatible monofilament fabric of monofilament threads with a smooth surface and in that on the monofilament fabric on its upper side facing away from the wound at least one cover element is fixed which is provided with the marker material.

Abstract: Method for producing a comb-shaped copolymer whose skeleton is of an acrylamide, acrylic acid, acryloyl aminoethanol or dimethyl acrylamide type and on which poly(N-alkyl acrylamide) or poly(N,N-5 dialkyl acrylamide lateral segments are grafted, includes (a) producing a telomer poly(N-alkyl acrylamide) or poly(N,N-dialkyl acrylamide) of formula (I) H2N—R1-Z-{CH2—C(R2) [C(?O)N(R3) (R4)]—}n—H (I) 10 by reacting in water a compound of formula (II) CH2?C(R2)—C(?O)—N(R3) (R4) (II) with a chain limiting compound of formula (III) Z-R1—NH2; (b) isolating the telomer of formula (I) obtained at a stage (a); (c) reacting in water the telomer of formula (I) obtained at stage (b) with an acid chloride of formula (IV) CH2?C(R5)—C(?O)—C1 at a molar ratio (IV)/(III) equal to or less than 10 and equal to or greater than 1 so that a macro monomer of formula (V) 20 CH2?C(R5)—C(?O)NH—R1-Z-{CH2—C(R2) [C(?O)N(R3) (R4)]—}n—H (V) is obtained; (d) isolating the macro monomer of formula (V) obtained at stage (c); (e) copolymerizing in
