Problems solved by technology

[0003] Silver can kill 650 different pathogens, while common antibiotics can only work on 6 kinds of germs on average; unlike antibiotics, silver is an "equal opportunity destroyer" and can kill all kinds of bacteria without distinction (G+ and G-bacteria, spore-forming bacteria), fungi / yeasts, viruses, mycoplasma and parasites, etc.

Embodiment Construction

[0014] (1) dyeing: adopt medical safe dyestuff to dye viscose fiber into yellow, dry;

[0015] (2) attach silver ion antibacterial agent: silver ion solution is poured into glass tank, and poplar fiber is put into padding, padding rate is 250%, and the time is about 10 minutes;

[0016] (3) Drying: Dry the poplar fibers at 150°C;

[0017] (4) Blended fabric: uniformly mix viscose fiber and poplar fiber in a ratio of 8:3 to weave into cloth, and the weight of the silver ion antibacterial layer is 100g / m 2 ;

[0018] (5) Composite absorbent layer on the non-wound contact surface of the silver ion antibacterial layer, compound PE film on the wound contact surface, composite into cloth, and the composite film is cut into rolls;

[0019] (6) Make and paste the silver ion water-absorbing pad, release paper, and adhesive non-woven fabric on the dressing making and pasting machine after composite cutting.

Abstract

The invention relates to a preparation method of a silver ion antibacterial medical dressing, and the preparation method comprises the following steps: dyeing, attaching a silver ion antibacterial agent, baking, mixing with viscose, weaving, slitting peritoneum, and preparing patch. Compared with similar products, the product has stronger infection resistance, can be used for remarkably accelerating wound healing, shortening the course of treatment and reducing the formation of scars. Clinical application proves that the silver ion antibacterial medical dressing is applicable to treatment of I-type, II-type and III-type cuts after an operation, has the advantages of safety, reliability, efficiency, no allergy occurrence and the like, and is suitable for clinical popularization and application.

Description

technical field [0001] The invention belongs to the technical field of antibacterial agents, in particular to silver ion antibacterial medical dressings. Background technique [0002] Infected wounds are difficult to heal because pathogens such as Staphylococcus aureus, Candida, and Escherichia coli can easily multiply on the wound. A medical dressing is a protective covering over a wound to help control bleeding, prevent infection, and absorb secretions. With the development of modern science and technology, new medical dressings are constantly appearing, and the clinical efficacy is also improving. Antibiotics are added to many medical dressings in order to protect the wound surface while preventing wound infection. Antibiotics are widely used in wound protection due to their rapid onset of antimicrobial action. However, the use of antibiotics has also accelerated the evolution of bacteria. More and more bacteria previously controlled by antibiotics have evolved into so...
