Problems solved by technology

[0003] Nano-silver, as a new type of nano-medical material, is widely used in the field of antibacterial and disinfection, but nano-materials have their limitations. When used externally, once the skin surface is damaged, nano-silver particles can easily enter the human body, stimulating the body's immune system to generate potential Adverse reactions, these defects greatly limit the application of medical nanomaterials including nano silver

Embodiment Construction

[0010] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention, and should not be construed as limiting the implementation of the present invention.

[0011] Such as figure 1 In the dressing shown, a base cloth 1, an adhesive layer 2, a protective layer 3 pasted on the adhesive layer 2 in the middle of the base cloth 1, the protective layer 3 is covered with a release paper 4, and the outer edge of the release paper 4 is fixed on the periphery of the base cloth 1 on the corresponding exposed part.

[0012] The internal structure of the protective layer is as figure 2 As shown, the protective layer 3 is nano-silver composite layer 3.1, spongy fabric layer 3.2, and non-woven reinforcing layer 3.3 in order from near to far from the base fab...

Abstract

Dressing with a nano-silver composite antibacterial layer and far infrared ceramics comprises base cloth, the inner surface of the base cloth is coated with an adhesive layer, the middle of the base cloth is pasted with protection layers, the protection layers are covered with release paper, the outer edge of the release paper is fixed to an exposed portion corresponding to the periphery of the base cloth, and the dressing is characterized in that the three protection layers are arranged, and sequentially comprise a nano-silver composite layer, a spongy fabric layer and a non-woven fabric reinforcing layer according to the distance away from the base cloth layer from near to far, the spongy fabric layer is soaked by the polymer mixtures of far infrared ceramic micro powder and polyethylene glycol 6,000, the weight percentage of the far infrared ceramic micro powder accounting for in the polymer mixtures is 20 percent to 30 percent, and the range of the particle size of the far infrared ceramic micro powder is 15 microns to 30 microns.

Description

field of invention [0001] The invention relates to a medical dressing. Background technique [0002] Medical dressings generally include an adhesive layer, a base cloth and a protective layer, which are attached to the surface of the wound through the protective layer to prevent further infection of the wound. By improving the composition and structure of the protective layer, improving its anti-infection and promoting healing effect has become a problem to be solved in the prior art. [0003] Nano-silver, as a new type of nano-medical material, is widely used in the field of antibacterial and disinfection, but nano-materials have their limitations. When used externally, once the skin surface is damaged, nano-silver particles can easily enter the human body, stimulating the body's immune system to generate potential These defects greatly limit the application of medical nanomaterials including nanosilver. Invention content: [0004] The invention provides a medical dress...
