Embodiment 1

[0019] 1. Selection and preparation of base material

[0020] The base material is gauze, which is prepared according to the prior art.

[0021] Second, the preparation of nano silver antibacterial dressing

[0022] After the gauze is cut into a certain shape (depending on the area of ​​the wound, the same below), 2 to 4 parts by weight of the gauze are mixed with 10 to 30 parts by weight of a nano-silver solution at a temperature of 5 to 25°C (prepared according to the method of Chinese patent CN101318224B). , the same below) to make an antibacterial dressing containing 100-500PPM (percentage by weight, the same below, realized by adjusting the concentration of the nano-silver solution) nano-silver solution, which is sterilized by cobalt 60.

Embodiment 2

[0024] 1. Selection and preparation of base material

[0025] The base material is polyvinyl alcohol composite sponge, prepared according to the prior art (CN 102274540A).

[0026] Second, the preparation of nano silver antibacterial dressing

[0027] After the polyvinyl alcohol composite sponge is cut into a certain shape, 5 to 9 parts by weight of the polyvinyl alcohol composite sponge is soaked in 150 to 200 parts by weight of a nano-silver solution at a temperature of 30 to 40°C to make it contain 800 to The antibacterial dressing of 1000PPM nano-silver solution is sterilized by cobalt 60 radiation.

Embodiment 3

[0029] 1. Selection and preparation of base material

[0030] The base material is polyvinyl formal composite sponge, which is prepared according to the prior art.

[0031] Second, the preparation of nano silver antibacterial dressing

[0032] After the polyvinyl formal composite sponge is cut into a certain shape, 4 to 6 parts by weight of the polyvinyl formal composite sponge is soaked in 50 to 120 parts by weight of nano-silver solution at a temperature of 40 to 60°C to prepare It becomes an antibacterial dressing containing 80-400PPM nano-silver solution, which is sterilized by cobalt 60 radiation.

Abstract

The invention relates to a preparation method of nano silver antiseptic dressing and simultaneously discloses an application of the antiseptic dressing. The preparation method comprises the steps that after base material is cut into certain shapes, 2 to 9 parts of the base material is soaked in 10 to 200 parts of nano silver solution at 3 to 90 DEG C, so as to obtain antiseptic dressing containing 10 to 1000 PPM nano silver solution, and then the antiseptic dressing is conducted to radiation sterilization through cobalt 60 to obtain the nano silver antiseptic dressing. The preparation method adopts soaking technology, ensures that the nano silver solution is sufficiently spread in the base material, and ensures that the antibacterial property of the nano silver solution is fully played, so that the base material has higher capability of killing or restraining pathogenic bacteria, and a better environment is created for rapid healing of a wound. Simultaneously, the prepared nano silver antiseptic dressing can promote tissue repair and regeneration, accelerates wound healing, and can be widely applicable to the treatment of infected wounds or operative incision.

Description

technical field [0001] The invention relates to a preparation method of a nanometer silver antibacterial dressing, and meanwhile, the invention also discloses the application of the antibacterial dressing. Background technique [0002] At present, the existing medical dressings mainly include materials such as gauze, non-woven fabrics, and sterile wound stickers. However, the antibacterial performance of this type of dressing cannot meet the needs of wound healing. [0003] Nano-silver, its antibacterial property is widely known, and its anti-bacterial property is better, therefore, nano-silver particles (solution) can be dispersed on the dressing, thereby play the role of sterilization and anti-inflammation. [0004] Chinese invention patent application CN1895683A discloses a nano-silver antibacterial dressing, which uses nano-silver particles to disperse in the dressing. The preparation method is relatively cumbersome and requires processing techniques such as padding, pre...
