Problems solved by technology

Most of these organic synthetic antibacterial agents have toxic and side effects, are harmful to the human body, have poor heat resistance, are easy to decompose, have odor, and have a short service life.
[0006] At present, most medical antibacterial dressings are mostly silver-based antibacterial products, which have many disadvantages such as not being washable, slow bactericidal effect, and high cost.

[0037] The substrate dressing of this example is three layers of pure cotton absorbent gauze, with a width of 23cm, a warp and weft yarn count of 32S, a warp yarn density of 12 yarns / 10cm, and a weft yarn density of 5 yarns / 10cm.

[0038] Preparation of antibacterial solution: Benzalkonium chloride, hexaalkyldimethylbenzyl ammonium chloride and metha-ammonium chloride are formulated into quaternary ammonium salt mixed antibacterial agent according to the mass ratio of 20:5:20; take 400g polyhexaethylene Methyl biguanide antibacterial agent, 40g prepared quaternary ammonium salt mixed antibacterial agent, 100g ethanol, and 99460g water were mixed at room temperature with a speed of 1000 rpm for 4 minutes to obtain an antibacterial solution.

[0039] Preparation of antibacterial dressing: immerse three layers of pure cotton degreasing gauze into the antibacterial mixture on-line, then roll it dry, adjust the pressure of the roll to control the liquid volume to 150%, and obtain th...

Embodiment 3

[0043] The substrate dressing of this example is pure cotton degreasing gauze, the width is 200cm, the warp and weft yarn counts are 40S, the warp yarn density is 19 / 10cm, and the weft yarn density is 9 / 10cm.

[0044]Preparation of antibacterial solution: benzalkonium chloride, hexaalkyldimethylbenzyl ammonium chloride and metha-ammonium chloride are formulated into quaternary ammonium salt mixed antibacterial agent according to the mass ratio of 30:3:10; take 200g polyurethane Base biguanide antibacterial agent, 60g prepared quaternary ammonium salt mixed antibacterial agent, 60g ethanol, 99680g water mixed 5 minutes to obtain antibacterial solution with the rotating speed of 1000 revs / min through stirrer at room temperature.

[0045] Preparation of antibacterial dressing: immerse pure cotton degreasing gauze into the antibacterial mixture, then dry it by rolling, adjust the pressure of the roll to control the liquid volume to 100%, and enter the drying room after rolling,...

Abstract

The invention discloses an antibiosis solution used for dressing, an antibiosis dressing and a preparation method for the antibiosis dressing. The antibiosis solution comprises, in parts by weight, 0.15-1 part of a biguanide antiseptic, 0.03-1 part of a quaternary-ammonium-salt antiseptic, 0.03-1 part of ethanol and 97-99.79 parts of water. The antibiosis dressing prepared from the antibiosis solution solves the disadvantages that conventional antibiosis dressings are not resistant to water washing, slow in sterilization effect, high in cost and the like. Under the same sterilization effect, the antibiosis dressing is low in antiseptic addition amount and relatively cheap in price; the antibiosis solution is good in bonding force and compatibility with a base material, is capable rapidly killing Gram-positive bacteria, Gram-negative bacteria and other multiple bacteria and fungi, and has wide-spectrum rapid bactericidal effect; and the antibiosis dressing is applicable to surgery wounds, burns, scalds and other chronic wounds, and provides a moist and bacterium-isolated environment for wounds. The antibiosis solution and the antibiosis dressing are simple in preparation technology, and large-scale industrialized production can be realized.

Description

technical field [0001] The application relates to the field of medical dressings, in particular to an antibacterial solution for dressings, an antibacterial dressing prepared from the antibacterial solution, and a preparation method for the antibacterial dressing. Background technique [0002] Because the surface of the wound generally has a warm and humid environment, bacteria multiply quickly on the wound, making the wound an important source of cross-infection in the ward. In recent years, with the rapid development of functional materials and the medical and health industry, various antibacterial materials have been added to many types of medical dressings. The antibacterial materials used include natural antibacterial agents, inorganic antibacterial agents and organic synthetic antibacterial agents. [0003] According to the source, natural antibacterial agents can be divided into plant sources, animal sources and microbial sources, including bamboo fiber, aloe, Houttu...
