New kind of wound dressing for haemostasis

Abstract

The invention relates to a wound dressing that has haemostatic, procoagulant and biocidal properties and can therefore be used more particularly for acute wound care. Typical application areas of acute wound care include for example the care of gunshot wounds. The new kind of wound dressing according to the invention has more particularly selected halloysites, which are applied for example to textile fibres or nonwovens.

Description

technical field [0001] The present invention relates to a wound dressing which has hemostatic, procoagulant and biocidal properties and is therefore especially useful for acute wound care. A typical field of application for acute wound care is, for example, the treatment of bullet wounds. In particular, novel wound dressings according to the invention feature selected halloysite clays, for example coated onto textile fibers or nonwoven materials. Background technique [0002] The state of the art recognizes several wound dressings for gunshot wounds. Many resources for treating gunshot wounds include, for example, bandages made of cotton or other types of materials. In addition, so-called gauze bandages have a gauze carrier layer coated with polyglucosamine. Hemostatic bandages coated with kaolin clay, which speeds blood clotting, are also known. In addition to kaolin, bandages can also be coated with zeolite particles, triple-layered silicates or diatomaceous earth. In...

Problems solved by technology

[0006] - Non-uniformity in the application or impregnation of fabric wound dressings due to known techniques and poor detachability from the treated wound, and due to High manufacturing costs due to the use of various additives;

[0007] - Natural minerals used in the prior art lack purity requirements; minerals do not meet pharmacopoeial purity requirements and are therefore evaluated as a critical factor in medical product approval;
