AI Technical Summary
Technical Problem
Existing gels have problems such as easy leakage in the vagina, inability to distribute evenly, dilution of concentration, and failure of the carrier before contact with the gel, resulting in poor treatment effects for HPV.
Method used
A sustained-release anti-HPV vaginal tampon gel carrier is formed by combining a gel containing anhydride-modified bovine β-lactoglobulin with a polyvinyl alcohol sponge and is separated by a water-soluble temperature-controlled PVA film, which is then precisely delivered via an injector.
Benefits of technology
The gel maintains an effective concentration and duration within the vagina, is evenly distributed, avoids carrier contact failure, prolongs drug action time, and improves HPV virus inactivation rate.

Abstract
The invention relates to the technical field of biological medicine auxiliary instruments, and particularly discloses a sustained-release type anti-HPV vaginal packing gel carrier and an injector thereof, the gel carrier is mainly composed of two parts, one part is gel containing anti-HPV active ingredients, and the other part is a carrier for promoting the gel to adhere to the body. And a layer of water-soluble temperature control PVA film is sprayed between the carrier and the gel. Through pushing of the injector, the carrier expands in the vagina to play a role of the carrier, and meanwhile, the gel is uniformly and effectively attached to the vagina wall due to the fact that wrinkles on the vagina wall are opened through expansion, and the situation that the gel flows out along with changes of the body position of a patient or is diluted by secretions to lose the effective acting concentration to affect the acting effect is avoided. The effect of killing the HPV virus can be effectively achieved. The sponge can actively adsorb a mixture containing viruses and drugs, and the contact rate of the viruses and the drugs is greatly increased. In addition, the adsorption effect of the sponge can continuously capture newly-fallen viruses, and the sponge has the effect of slowly releasing drugs and better resists HPV viruses.
