Problems solved by technology

Silicone oil lubricant is greasy, not easy to clean, and it will cause gynecological diseases if used for a long time
Water-soluble lubricants are soluble in water and easy to clean, but the water in them often causes changes in the physical and chemical properties of condoms. At the same time, water-soluble lubricants are also prone to bacteria and require the addition of preservatives, which is not conducive to human health

Abstract

The invention provides a condom with a natural antibacterial hydrophilic lubrication coating, which is characterized in that the main hydrophilic components are a polymer or a copolymer formed by one or more monomers of polyacrylamide, polyethylene glycol, polyvinylpyrrolidone, carboxymethyl cellulose, hydroxyethyl cellulose and hydroxypropyl methyl cellulose; and chitosan, a plant extract with antibacterial action and a mixture of the chitosan and the plant extract are added to the hydrophilic lubrication coating. The condom spontaneously generates the lubrication action when meeting the moisten environment of the vagina in the course of the sexual life, and simultaneously absorbs and inhabits the microorganisms of the vagina so as to clean the vagina.

Description

technical field [0001] The invention relates to a medical device, in particular to a condom, in particular to a condom with a natural antibacterial hydrophilic lubricating coating. Background technique [0002] Condoms are an effective tool for human family planning and AIDS prevention. It is a daily product with a large annual consumption, and the development of a new type of condom has great practical and economic value. Existing condoms are basically all added with lubricating liquid, a kind of is silicone oil, and a kind of is water-soluble lubricant. Silicone lubricants are greasy, not easy to clean, and can cause gynecological diseases if used for a long time. Water-soluble lubricants are soluble in water and easy to clean, but the water in them often causes changes in the physical and chemical properties of condoms. At the same time, water-soluble lubricants are also prone to breed bacteria and require the addition of preservatives, which is not conducive to human h...
