Problems solved by technology

[0006] Known from the above-mentioned prior art, with regard to the use of antimicrobial precious metals in medicine, especially the use of coverings, so far still focus on the use of these precious metals alone, and at most only involve the use of these precious metals in the form of alloys or compounds. Metals, none of which relate to the use of precious metals supported on carbonaceous materials
Furthermore, the aforementioned known uses, while providing a microbicidal benefit, only destroy microorganisms when they "just happen" to come into contact with the precious metal, and at best only provide a "passive" negative microbicidal benefit

Embodiment Construction

[0037] The wound covering of the present invention comprises a carbonaceous material, a precious metal carried on the carbonaceous material, and an optional flexible base material layer, wherein the flexible base material layer has a first surface and a second surface, and the loaded The carbonaceous material of noble metal covers at least a part of the first surface.

[0038] The flexible substrate layer contained in the wound covering of the present invention may be porous or impermeable to agents. If a wound covering such as gauze or a bandage is to be provided, the flexible substrate is advantageously constructed of a porous, preferably non-adhesive material. However, if a wound covering such as a patch is to be provided, a drug impermeable substrate is advantageously used. Generally known materials that can be used to provide a wound cover and meet the aforementioned porosity or drug impermeability can be used in the present invention. By way of example, but not limitat...

Abstract

The invention discloses a wound coverture and an antimicrobial composition. The wound coverture comprises a carbon material, precious metals carried by the carbon material and a flexible substrate layer selected according to requirements, wherein the carbon material is in the shapes of powder, grain, fiber and / or a thin sheet, and is selected from the following groups: active carbon, graphite, carbon and compounds thereof, and the precious metals are selected from the following groups: silver, gold, palladium, platinum, copper, zinc and compounds thereof. The antimicrobial composition is partially applied to skin, and contains the carbon material and the precious metals carried on the carbon material.

Description

[0001] This application is a divisional application of the Chinese invention patent application filed on September 25, 2006 with the application number 200610152642.9 and the invention title "Antimicrobial Composition and Wound Cover". technical field [0002] The present invention relates to the use of precious metals supported on carbonaceous materials in antimicrobial compositions and antimicrobial wound coverings. In particular, the present invention relates to antimicrobial compositions and wound coverings containing precious metals supported on activated carbon or porous graphite, which, in a proactive manner, aggregate and thereby destroy microorganisms approaching the compositions and wound coverings, thereby preventing the combination The material or wound covering and the object to which it is applied are infected with microorganisms. Background technique [0003] With the evolution of science and technology, for the treatment of traumatic parts of the body, in add...
