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
Invention field
The present invention relates to a kind of medical dressing.
Background technology
Medical dressing generally comprises adhesive-layer, Ji Bu and protective layer, and it is covered on wound surface by protective layer, stops the further infection of wound.By improving composition, the structure of protective layer, improving its infection promoting healing effect and becoming problem to be solved in prior art.
Nanometer silver, antibiotic and sterilizing field is widely used in as novel nano medical material, but nano material has it to use limitation, when the outer used time, once skin surface has breakage, nano silver particles easily enters human body, and stimulate the immune system of human body thus produce potential untoward reaction, these defects significantly limit the application of the medical nano material comprising nanometer silver.
Summary of the invention:
The invention provides a kind of medical dressing, comprise base cloth 1, base cloth inner face is coated with adhesive-layer 2, protective layer 3 is pasted with in the middle part of base cloth, protective layer is covered with from paper 4, be fixed on exposed parts corresponding to base cloth periphery from paper outer rim, it is characterized in that described protective layer is divided into three layers, extremely far nanometer silver composite bed 3.1 is followed successively by by near according to distance base cloth layer, sponge-like fabric layer 3.2, non-woven fabrics enhancement Layer 3.3, described sponge-like fabric layer far-infrared ceramic micropowder 3.21 floods with the polymeric blends of polyethylene glycol 6000, described polymeric blends mid and far infrared ceramic percentage by weight is 20-30%, far-infrared ceramic micropowder particle size range is 15-30 μm.
Described nanometer silver composite bed adopts the Macrogol 4000 of percentage by weight 90%-93% and the nano silver particles 3.11 of surplus to form, and nano silver particles is evenly distributed in nanometer silver composite bed, and the D90 particle diameter of described nano silver particles is 20-30nm.
Described sponge tissue layer impregnated polymer mixture, adopts and Polyethylene Glycol is dissolved in suitable quantity of water, then add far-infrared ceramic micropowder, after suspension is made in mixing, for flooding sponge tissue layer, then dry.
Dressing provided by the present invention, adopt multi-protective layer, bottom sponge tissue layer, be provided with nanometer silver composite bed, simultaneously in order to prevent the excessive release of nanometer silver, adopt biocompatibility polymer---Polyethylene Glycol is fixed, due to the water solublity that polyvinyl alcohol itself also possesses, the dressing made like this, after wrapping, nanometer silver can be discharged slowly, can continue to play antibacterial action, therefore can wrap up for a long time without the need to changing dressings, simultaneously by flooding with far-infrared ceramic micropowder in sponge tissue layer, after making wrapping fixing, dressing can circulate thus accelerating wound healing by releasing far infrared promotion body blood.
Accompanying drawing illustrates:
Fig. 1 is for the invention provides dressing overall structure schematic diagram
Fig. 2 is protective layer internal structure schematic diagram
Detailed description of the invention
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention, can not be interpreted as the restriction to embodiment of the present invention.
Dressing as shown in Figure 1, base cloth 1, adhesive-layer 2, in the middle part of base cloth 1, adhesive-layer 2 is pasted with protective layer 3, protective layer 3 is coated with from paper 4, is fixed on exposed parts corresponding to base cloth 1 periphery from paper 4 outer rim.
As shown in Figure 2, described protective layer 3 is extremely far followed successively by nanometer silver composite bed 3.1, sponge-like fabric layer 3.2, non-woven fabrics enhancement Layer 3.3 according to distance base cloth layer 1 by near to protective layer internal structure.And be fixed on the adhesive-layer 2 on base cloth layer by the polyvinyl alcohol of nanometer silver composite bed, the sponge-like fabric layer polymeric blends of far-infrared ceramic micropowder 3.21 with polyethylene glycol 6000 floods, and nano silver particles 3.11 is evenly distributed in nanometer silver composite bed 3.
