ANTISEPTIC WOUND DRESSING
20200000956 · 2020-01-02 ·

The antiseptic wound dressing includes at least nanometer chitin, alkaline earth metal alginate, and an antiseptic material. The nanometer chitin is tubular shaped having diameter 1050 nm and length 20200 nm. The amount of the nanometer chitin is 0.1%5% to the alkaline earth metal alginate. The antiseptic wound dressing is manufactured by mixing nanometer chitin and alkaline earth metal alginate, further mixing with antiseptic material, conducting a wet spinning process to produce fibers, and conducting a non-woven cloth process to obtain the antiseptic wound dressing of the present invention. Therefore, the antiseptic wound dressing is capable of reducing the chance of would infection, and providing superior moisture retention and enhanced wet strength.

SOLID DRESSING FOR TREATING WOUNDED TISSUE AND PROCESSES FOR MIXING FIBRINOGEN AND THROMBIN WHILE PRESERVING FIBRIN-FORMING ABILITY, COMPOSITIONS PRODUCED BY THESE PROCESSES, AND THE USE THEREOF

Fibrin Sealant products are used for topical hemostasis and tissue adherence. They are composed of two main reagents, fibrinogen and thrombin. When mixed in solution fibrinogen is converted to fibrin upon the addition of activated thrombin. Therefore typically these two components are stored separately in a lyophilized or liquid state, and mixed, upon or immediately before, application to a patient. While effective, these products require significant preparation that must take place immediately before application, thus delaying treatment and limiting the use of these haemostatic products to the treatment of mild forms of low pressure and low volume bleeding. Attempts to eliminate this delay and expand the usefulness and effectiveness of these products have resulted in products produced by processes that require the separation of these components and their deposition in distinct layers within the product. The processes described herein permit the mixing of fibrinogen and thrombin during product manufacture, without excessive fibrin formation. The resulting pre-mixed fibrin sealant material can then be stored in either a frozen or dried state, or suspended in a non-aqueous environment. Activation of the material to form therapeutic fibrin sealant is accomplished by permitting the product to thaw (if frozen) or by the addition of water or other aqueous fluid, including blood, or other bodily fluids, if dried or suspended in a non-aqueous environment. The resulting material can be used to make a product in which a pre-mixed form of activatable fibrin sealant is a desired component.

SOLID DRESSING FOR TREATING WOUNDED TISSUE AND PROCESSES FOR MIXING FIBRINOGEN AND THROMBIN WHILE PRESERVING FIBRIN-FORMING ABILITY, COMPOSITIONS PRODUCED BY THESE PROCESSES, AND THE USE THEREOF

Disclosed are solid dressings for treating wounded tissue in mammalian patients, such as a human, comprising a haemostatic layer consisting essentially of a fibrinogen component and a fibrinogen activator, wherein the haemostatic layer(s) is cast or formed from a single aqueous solution containing the fibrinogen component and the fibrinogen activator. Also disclosed are methods for treating wounded tissue using these dressings and frozen compositions useful for preparing the haemostatic layer(s) of these dressings.

Disinfecting wound dressing and process for preparing such

A process for preparing a disinfecting wound dressing for the protection of wounds, such as burn wounds, ulcers and cuts, the process comprising the steps of providing a yarn-based substrate, subjecting a surface of the substrate to a plasma environment, thereby providing non-leaching and biocidal features to the substrate surface by exposing the substrate surface to an antimicrobial active compound reaction.
