Claims14
Wound cleaning device having a carrier layer and, arranged thereon, a wound cleaning layer designed to hold wound exudate and/or solid wound components and having cleaning threads, characterized in that the carrier layer and/or the wound cleaning layer is provided with at least one storage material that increases the holding capacity for wound exudate.
Wound cleaning device according to any one of the preceding claims, characterized in that the cleaning threads form loops and/or have freely cantilevered ends.
Wound cleaning device according to any one of the preceding claims, characterized in that, based on the dry weight of carrier layer and cleaning layer, the proportion of at least one storage material is 0.1% 25% by weight, in particular 0.15%-20% by weight, preferably 0.2%-17% by weight.
Wound cleaning device according to any one of the preceding claims, characterized in that, based on the dry weight of cleaning layer, the proportion of at least one storage material is 0.2%-30% by weight, in particular 0.25%-27% by weight, preferably 0.3%-25% by weight.
Wound cleaning device according to one of the preceding claims, characterized in that at least the cleaning layer is impregnated using a preferably aqueous solution of the storage material.
Wound cleaning device according to any one of the preceding claims, characterized in that the storage material has at least one surfactant and/or at least one substance that swells on contact with water or an aqueous solution.
Wound cleaning device according to any one of the preceding claims, characterized in that the storage material contains at least one cellulose ether, in particular hydroxyethyl cellulose, carboxymethyl cellulose, methyl cellulose, ethyl cellulose and/or hydroxypropyl cellulose, additional polysaccharides, such as dextrans, starch, chitosan, carrageenan and alginates, milk protein, hyaluronic acid, sugar alcohols, glycols, salts and/or blends thereof.
A process for producing a wound cleaning device according to any one of the preceding claims, in which at least the wound cleaning layer of the wound cleaning device is impregnated using a preferably aqueous solution of the storage material.
Pack having a fluid impermeable sheath and a wound cleaning device according to any one of the preceding claims held therein.
Kit for producing a wound cleaning device according to any one of the preceding claims, having a dry wound cleaning cloth and a preferably aqueous solution of at least one storage material.
Use of a storage material for a wound cleaning device for wound bed preparation, wherein substances formed by the body itself, such as excess fluids, fibrin plaques, dead tissue of the epidermis, such as excess horn material or dead horn cells and/or plaques from dead tissue (necroses), are removed.
