Problems solved by technology

[0004] In terms of clinical use, anti-infective drugs account for one-third of the total dosage, but it is not ideal. It is believed that "bacteria are becoming more and more drug-resistant, and antibiotics are becoming more and more ineffective". The reason is that these antibiotics, sulfonamides, etc. All of them block or inhibit the metabolic growth of bacteria through the change of chemical structure. If this link does not work, we will replace it with another link, called second-generation and third-generation antibiotics. Most of the bacteria are inhibited to die, but some bacteria always remain. Their next generation adapts to these drugs by changing their genes, that is, develops resistance

example 1

[0043] According to the method described in the application number 94118576.1, the name is: long-acting broad-spectrum antibacterial particles and the preparation method of the products thereof to prepare broad-spectrum antibacterial particles.

[0044] A, get 100 grams of rush stem pith dry material, pulverize to millimeter level, set aside;

[0045] B. Take by weighing 5-20 grams of silver nitrate and dissolve in 500 milliliters of water and 50-100 milliliters of concentrated ammonia water, dissolve and dilute to 1000 milliliters, shake well, then add a solution containing 3-10 grams of vitamin C to this solution ( Volume 50 milliliters), put into the granules obtained in step A immediately, soak and extrude under ventilated conditions, then soak and extrude, then heat-treat, soak and extrude, and finally dry to obtain the required broad-spectrum Antibacterial particles.

example 2

[0047] Weigh the following raw materials according to the following proportions

[0048] Nano silver particles 1g, polycarboxyethylamine 6g, triethanolamine 9ml,

[0049] Distilled water 9984 grams.

[0050] Prepare as follows:

[0051] Stir the nano-silver particles, polycarboxyethylamine and triethanolamine evenly at room temperature according to the above ratio, then add distilled water and continue to stir for 1.5 hours, cool to solidify under stirring, and divide into packages.

example 3

[0053] Weigh the following raw materials in the following proportions:

[0054] 3.5 grams of nano-silver particles, 12 grams of polycarboxyethylamine, 15 ml of triethanolamine,

[0055] Distilled water 9969.5 grams.

[0056] Prepare as follows:

[0057] Stir the nano-silver particles, polycarboxyethylamine and triethanolamine evenly at room temperature according to the above ratio, then add distilled water and continue to stir for 1.9 hours, cool to solidify under stirring, and pack it separately.

Abstract

A disinfecting nano silver gel for treating bacterial vaginitis, prostatitis, burn, scald, wound, etc. contains pharmacologically receptable additive, carrier, and broad-spectrum antibacterial nano silver particles (0.1-0.4%) with 1-100 nm of granularity.

Description

1. Technical field [0001] The invention relates to an antibacterial drug using nano-silver, more particularly to a nano-silver disinfectant gel and its preparation method and application. 2. Background technology [0002] Nanotechnology is the study of physical and chemical properties of substances in a size range (ie, 0.1 to 100 nanometers) between the macrocosm and the microcosm. In this range, it is different from both the macrocosm and the microcosm. Therefore, when the United States determined nanotechnology in the 1990s, it defined this interval as mesoscopic. The matter in the mesoscopic not only maintains the atomic form of matter in the macroscopic state, but also produces small-scale effects and quantum effects due to changes in atomic arrangement. Effect, so that the substance has extraordinary adsorption, diffusivity and surface activity. The application of these properties can change the way people live, generate new revolutions in many industries, and it is th...
