Abstract: An application of a hydrogel in the preparation of products for the treatment of bacterial infection is disclosed. Ferrous ion was used in the antibacterial activity test of Staphylococcus aureus and showed a strong bactericidal effect, which the survival rate of Staphylococcus aureus is less than 0.001%, as well as the survival rate of methicillin-resistant Staphylococcus aureus (MRSA) was less than 0.01%. Ferrous ion hydrogel was used for the treatment of keratitis and skin wound infection. Ferrous ion hydrogel for the treatment of keratitis and skin wound infection, which can significantly reduce the risk of pulmonary MRSA infection, prevented the dissimilation of MRSA to the lung, and alleviated systemic inflammation in the body in a timely and effective manner, revealing the therapeutic potential of ferrous compounds for treatment of Staphylococcus aureus infections, including MRSA.

Abstract: The present invention discloses a wound dressing and the method of manufacturing. The wound dressing is a knitted fabric including of a fluffy layer of gel-forming fibers and a backing layer of non-gel-forming fibers. The backing layer includes a plain fabric of the non-gel-forming fibers. The gel-forming fibers are knitted onto the backing layer, a middle part of the gel-forming fibers are held in the backing layer, and two ends of the gel-forming fibers project against the backing layer. The length of the middle part of the gel-forming fibers is no more than the length of one loop of the non-gel-forming fibers, and the length of each of the two ends of the gel-forming fibers is between 1-100 mm.

Abstract: A wound dressing, including fibers containing silver ions. The fibers are manufactured by dissolving silver nitrate into a polymer solution in the substantial absence of light, and then extruding the obtained solution into fibers by wet spinning process. The silver content of the wound dressing is between 0.01-10% by weight, and preferably 0.1-7% by weight.

Abstract: A wound dressing, including: a first outer layer, a second outer layer, and a middle layer disposed between the first outer layer and the second outer layer. The volume density of the first outer layer and a volume density of the second outer layer are greater than that of the middle layer; the first outer layer, the second outer layer, and the middle layer are bonded together.

Abstract: A three-layered wound dressing, including: a first layer, a second layer, and a third layer. The first layer includes a blend of first hydrophilic fibers and first hydrophobic fibers, the second layer includes a blend of second hydrophilic fibers and second hydrophobic fibers, and the third layer includes hydrophobic fibers. The second layer is disposed between the first layer and the third layer. In use, the first layer contacts a wound.

Abstract: The present invention relates to a silver containing antimicrobial fibre, fabric and wound dressing and its method of manufacturing. Silver ions are evenly distributed in the interior or on a surface of an antibacterial fibre structure. The silver content in the dressing is 0.01-10 weight %. As wound treatment dressing, the fibre wound dressing has a capability of continuously releasing a sufficient amount of silver, is particularly suitable for chronic wound treatment, can provide a long-term and effective antibacterial function, and can effectively prevent various bacteria or other microorganisms from infecting a wound.

Abstract: The present invention discloses a wound dressing with high absorption capacity and the method of manufacturing. The wound dressing is a knitted fabric comprising of a fluffy layer of gelling fibres and a layer of non-gelling fibres as the backing. The gelling fibres are knitted onto the backing structure and the length fluffy fibre outside the backing structure is between 1-100 mm, preferably 5-50 mm. The wound dressing can be used to manage chronic wounds such as venous stasis ulcers, pressure ulcers, diabetic foot ulcers and other chronic ulcer wounds.

Abstract: A wound dressing comprising acylated chitosan fibre. The dressing has a wet strength of 0.3 N/cm or above. The acylated chitosan fibre may have a degree of substitution of 0.10-0.50. The acylated chitosan fibre may preferably have a degree of substitution of 0.20-0.40. The dressing may have an absorbency of 5-25 g/g of a solution containing 8.298 g/l of sodium chloride and 0.368 g/l of calcium chloride dehydrate as measured by BSEN 13726-12002 Part 1 Aspects of Absorbency. The base material of the dressing may be chitosan fibre that has been chemically modified through an acylation process using anhydride and ethanol as the solvent. A method of manufacturing the wound dressing involves reacting chitosan fibre with anhydride and making acylated chitosan felt through a nonwoven process, and through cutting, packing and sterilizing processes.

Abstract: A wound dressing with bacteriostatic and hygroscopicity, preparation method therefore, and the use thereof in preparing a product for treating chronic wounds. The dressing comprises chitosan fiber and modified cellulose fiber.

Abstract: The present invention discloses an antimicrobial fibre, fabric and wound dressing that incorporate nano metal and the preparation method thereof. Nano metal particles are homogenously distributed within the fibre structure or surface, and, the fibre does not contain protective colloid for the prevention of agglomeration of nano metal particles. The nano metal particles are in an amount of 1.1% to 20% by weight. The fibrous wound dressing has the ability to continuously release sufficient amount of silver ions and is especially suitable for the management of chronic wounds. It can effectively prevent various bacteria and microbial infections.
