Problems solved by technology

The U.S. Centers for Disease Control and Prevention also pointed out in the guidelines for the treatment of sexually transmitted diseases issued in 2006 that when treating bacterial and candidal vaginitis, azole drugs such as metronidazole (metronidazole), butoconazole (butoconazole), gram Drugs such as clotrimazole, miconazole, or nystatin. However, the above-mentioned treatment methods have their own shortcomings. For example, taking antibiotics may cause bacteria to develop drug resistance. Suppositories and topical ointments are not easy to dispose of personally. Using antibiotics or various medicines sometimes takes more than 10 days of treatment, and cryotherapy and other methods are not immediately effective. However, vaginal infection is the most common thing women turn to gynecologists for help One of the reasons for diagnosis and treatment, the shortcomings of the aforementioned treatment methods are really important issues to be solved

Embodiment 1

[0054] Activated carbon fiber cloth (BET value 1050m 2 / g) as a raw material, the activated carbon fiber cloth was impregnated in 0.01M silver nitrate and copper nitrate aqueous solution, while stirring for 1 hour with 50rpm rotating speed, after that, dehydrated, and dried at 120°C to remove the water phase.

[0055] The impregnated activated carbon fiber cloth was placed under the protection of nitrogen, and the temperature was raised from room temperature to 600 °C at a rate of 4 °C / min, followed by thermal cracking for 1 minute, and then cooled to room temperature at a rate of 10 °C / min.

[0056] Then wash with water for 2 hours, and then dry at 120° C. for 2 hours to obtain the final product. Tested according to the aforementioned measurement method, the results show that the silver content of the resulting product accounts for 0.06% by weight of the total weight, and the silver particles on the activated carbon fiber are nano-scale, and its size is about 10 to 50 nanomet...

Embodiment 2

[0061] Using phenolic activated carbon fiber felt (BET value 1420m 2 / g) as a raw material, prepared in the same procedure as in Example 1. The test results show that the silver content of the obtained product accounts for 0.07% by weight of the total weight, and the size of the silver particles is about 50 to 200 nanometers. The content of copper accounts for 0.04% by weight of the total weight, and the copper particles on the activated carbon fiber are nanoscale, with a size of about 100 to 500 nanometers.

[0062] Activated carbon fiber felt loaded with copper and silver particles, its true density is 2.04g / cm 3 , the carbon content is 85.8wt%, the oxygen content is 13.2wt%, and the BET specific surface area is 1380m 2 / g.

[0063] The above-mentioned activated carbon fiber felt loaded with copper and silver particles is made into feminine hygiene products as in Example 1.

Embodiment 3

[0065] Using fireproof fiber felt, activated with water vapor at 800°C for 10 minutes to make polyacrylonitrile-based activated carbon fiber felt (BET value 632m 2 / g) as raw material, impregnated in 0.01M silver nitrate and copper nitrate aqueous solution for 5 hours under vacuum state. Afterwards, dehydration was carried out, and drying was carried out at 120° C. for 2 hours to remove the water phase. Then place the impregnated activated carbon fiber felt in a 400° C. high-temperature furnace filled with nitrogen, and carry out thermal cracking for 90 minutes. Next, the silver-loaded activated carbon fiber felt was washed with water at 4.5 liters / minute for 3 hours, and then dried at 120° C. for 2 hours to obtain the final product. The test results show that the silver content of the obtained product accounts for 0.04% by weight of the total weight, and the size of the silver particles is about 50 to 200 nanometers. The content of copper accounts for 0.02% by weight of the...

Abstract

The present invention relates to a woman sanitary article, the tampon structure comprise at least one absorbent carbonaceous base with at least two precious metals, an absorber, a surface layer, and a rope. The copper ions and silver ions can be released by the at least two precious metals in aqueous solution to reach the health effects of the female vagina.

Description

technical field [0001] The invention relates to a feminine hygiene product, which contains a liquid-absorbing carbonaceous substrate and precious metals, has the functions of absorbing peculiar smell and sterilizing bacteria, and can be used in the category of female sanitary products. Background technique [0002] Infection, inflammation and other discomfort symptoms of female genitals are collectively referred to as vaginitis. Common symptoms include genital itching, redness, pain, burning sensation, and increased abnormal secretions. These symptoms may be caused by infections, allergies, irritants, improper cleaning, poor personal hygiene habits, changes in vaginal pH, changes in flora, etc. There are three common types of vaginitis: bacterial vaginosis (about 40-50%), candidal vaginitis (about 20-25%), vaginal trichomonas infection (about 15-20%), and There are also multiple infections, pinworm infection, or vaginal inflammation caused by non-infectious factors. [000...
