Problems solved by technology

[0003] Nano-zinc oxide, as a new type of nano-medical material, is widely used in the field of external antibacterial and anti-inflammation, but nano-materials have their limitations, the skin surface is damaged, and nanoparticles enter the human body, which can easily stimulate the human immune system and cause potential adverse reactions. These defects greatly limit the application of medical nanomaterials including nano-ZnO

Embodiment Construction

[0008] 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.

[0009] Such as figure 1 In the dressing shown, the base cloth 1 has an adhesive layer 2, the adhesive layer 2 in the middle of the base cloth 1 is pasted with a protective layer 3, the protective layer 3 is covered with a release paper 4, and the outer edge of the release paper 4 is fixed on the base cloth 1 on the corresponding exposed part of the periphery.

[0010] The internal structure of the protective layer is as figure 2 As shown, the protection layer 3 is composed of nano-zinc oxide composite layer 3.1, spongy fabric layer 3.2, and non-woven fabric reinforcing layer 3.3 in order f...

Abstract

A dressing with a nano zinc oxide composite antibacterial layer and far-infrared ceramic micro powder is provided with base cloth, the inner face of the base cloth is coated with a viscose layer, protecting layers adhere to the viscose layer in the middle of the base cloth, the protecting layers are covered with release paper, and the outer edge of the release paper is fixed to the corresponding exposed part on the periphery of the base cloth. The dressing is characterized in that three protecting layers exist and are the far-infrared nano zinc oxide composite layer, the sponge-shaped fabric layer and the non-woven fabric reinforcing layer in sequence with the distance from the protecting layers to the base cloth becoming larger and larger, and the thickness of the nano zinc oxide composite layer ranges from 0.5 mm to 1 mm; according to the formation mode, the polymer base bottom is coated with nano zinc oxide and far-infrared ceramic micro powder, the D90 particle diameter of nano zinc oxide particles ranges from 30 nm to 50 nm, the particle diameter of the far-infrared ceramic micro powder ranges from 10 microns to 15 microns, and nano zinc oxide particles with the volume accounting for 5% to 10% that of the viscose layer are further evenly distributed in the viscose layer.

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-zinc oxide, as a new type of nano-medical material, is widely used in the field of external antibacterial and anti-inflammation, but nano-materials have their limitations, the skin surface is damaged, and nanoparticles enter the human body, which can easily stimulate the human immune system and cause potential adverse reactions. These defects greatly limit the application of medical nanomaterials including nano-zinc oxide. Invention content: [0004] The invention provides a m...
