Release date: 2014-09-04 According to foreign media reports, at present, American scientists pointed out that the latest development of a soluble tampon can quickly and effectively prevent HIV infection in women. The United States is considered to be a high-incidence area for AIDS. The current AIDS prevention measures are daily oral medications to avoid HIV infection. In recent years, some new methods of topical protection have been introduced, including: gels and films, which are inserted into the vagina before sexual intercourse, and these methods are still in the process of continuous improvement. But experts point out that these new products can't effectively suppress AIDS in clinical trials because they are difficult to use. Researchers at the University of Washington have recently developed a soluble fiber that can be inserted into a female vagina as an applicator, similar to a sanitary cotton ball used by women. Bioengineers believe that the newly developed soluble tampon can deliver topical drugs to protect women from HIV infection quickly and effectively. This method involves rotating the drug in filamentous fiber cotton, which dissolves quickly when exposed to moisture. This means that high doses of drugs can be used to prevent HIV infection, which is more effective than gels and films. Cameron Ball, head of the research report, said: "This will provide women with a safer and more effective way to prevent HIV infection, just by inserting a compressible tampon into the vagina of women before sex. in." It is reported that the research team had previously designed an electric rotating material that was inserted into the female vagina to explain the drug. The newly developed soluble tampon carries 10 times the concentration of anti-AIDS gel. Oral pills are most commonly used when people think they may be at risk of contracting HIV. In addition, there are some topical drugs in the form of gels and films that dissolve and spread the drug to the tissues surrounding the reproductive organs. A drug called a "microbicide" must be applied in large doses a few minutes before sex to effectively prevent AIDS, but so far, the clinical application of topical dressing is not obvious, in part because the operation is not simple. It takes at least 15 minutes for the drug in the form of a film to completely melt in the human body, while the gel requires a large amount of application, but sometimes it is necessary to pay attention to leakage. Bauer said: "The effectiveness of anti-AIDS topical drugs depends on high doses and rapid release. We apply high-concentration drugs to the tampon, so users do not need to insert a large amount of tampon in the vagina." The team noted that the soft soluble fiber can be rolled into a tampon applicator, inserted into the vagina or formed into a vaginal ring structure similar to contraceptive use.
