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
The present invention relates to a kind of medical apparatus and instruments, is condom specifically, relates in particular to a kind of natural antibacterial hydrophilic lubrication coating condom.
Background technology
Condom is human family planning and the effective tool that prevents AIDS.Be a kind of year very big articles for daily use of consumption, the development of new condom has great practical value and economic worth.Existing condom substantially all is added with lubricating fluid, and a kind of is silicone oil, and a kind of is soluble oil.Silicone lubricant is greasy, is not easy to clean, and long-time use also can cause gynaecopathia.Soluble oil is water-soluble, easy cleaning, but wherein moisture often causes that the condom physicochemical properties change, the also easy breed bacteria of soluble oil needs to add antiseptic simultaneously, is unfavorable for health.
Summary of the invention
The objective of the invention is at above weak point, a kind of antibiotic property hydrophilic lubrication coating condom is provided, need not additionally to add lubricant.Be applicable to and play lubrication in the sexual life can certain absorption and inhibitory action be arranged to vaginal bacteria simultaneously, the cleaning vagina.
To achieve these goals, the technical scheme taked of the present invention is: a kind of antibiotic property hydrophilic lubrication coating condom.Adhere to or crosslinked the hydrophilic lubricant coating arranged in condom outer surface side, the main hydrophilic composition of this coating is a polyacrylamide, polyvinylpyrrolidone, Polyethylene Glycol, carboxymethyl cellulose, hydroxyethyl-cellulose, a kind of or more than one described monomeric any copolymer or homopolymer in the hydroxypropyl emthylcellulose.In this hydrophilic lubricant coating, add the natural antimicrobial substance chitosan or the plant extract of antibacterial action is arranged, such as Folium Bambosae extract, Radix Glycyrrhizae extract, Rhizoma Curcumae Longae extract etc.
Comprise polyacrylamide (Polyacrylamide) at hydrophilic coating of the present invention.Polyacrylamide is called for short PAM, is polymerized by acrylamide monomer, and be a kind of water solublity linear macromolecule material.Monomer acrylamide chemical property is very active; can carry out a series of chemical reaction at two keys and amide groups place; adopt different technology, import different functional groups, can obtain different electric charge products: anion, cation, nonionic, amphion polyacrylamide.Product appearance is a white powder, soluble in water, be dissolved in benzene hardly, common organic solvents such as ether, esters, acetone, the thick liquid of several near-transparents of its aqueous solution belongs to non-dangerous article, nontoxic, non-corrosiveness, solid PAM has hygroscopicity, and hygroscopicity increases with the increase of ion degree, the PAM Heat stability is good; Be heated to 100 ℃ and have good stability, but easily decompose more than 150 ℃ the time produce in nitrogen, in intermolecular generation imidization effect and water insoluble.
The polyacrylamide characteristic mainly contains following 4 points:
1) flocculability: PAM can make suspended material by charge neutrality, and the bridge formation adsorption plays flocculation.
2) cohesive: can play adhesive effect by effect machinery, physics, chemistry.
3) fall resistive: PAM can reduce fluidic frictional resistance effectively, adds trace P AM in the water and just can fall and hinder 50-80%.
4) thickening property: PAM all has thickening power under neutral and acid condition, when pH value at 10 above PAM facile hydrolysiss.When being half network structure, thickening will be more obvious.
Comprise Polyethylene Glycol at hydrophilic coating of the present invention.Polyethylene Glycol chemistry structure: HO (CH2CH2O) nH is formed by ethylene oxide polymerization.English abbreviation is PEG.The extensive compatibility of low-molecular-weight PEG and all kinds of solvents is good solvent and solubilizing agent.Can be used as solvent, cosolvent, o/w type emulsifying agent and stabilizing agent.Intermediate molecular weight PEG is used as substrate or lubricant, softening agent in medicine, weaving, cosmetics industry; Be used as dispersant in coatings industry, improve water dispersible, the pliability of resin, consumption is 10-30%; Can improve the solvability of dyestuff in the printing ink, reduce its volatility, especially suitable in paraffin paper and ink pad printing ink, also can in ball pen ink, make to regulate the printing ink viscosity and use; In rubber industry, make dispersant, promote sulfurization, as the dispersant of white carbon black casting resin.High molecular weight PEGs as excipient, is used as the preparation of suppository, unguentum in medical industry; Be used as finishing agent in the paper industry, increase the gloss and the flatness of paper; In rubber industry,, increase the lubricity and the plasticity of rubber, reduce the power consumption in the course of processing, prolong the service life of rubber as additive.
Comprise polyvinylpyrrolidone at hydrophilic coating of the present invention.The polyvinylpyrrolidonemolecules molecules formula is (C6H9NO) n.Outward appearance is white or off-white powder or granule, is a kind of runny powder of hygroscopicity that has, odorless or little smelly, water-soluble, alkali, acid and polar organic solvent, have very strong expansion character and with the complexing power of multiclass material.
Polyvinylpyrrolidone (polyvinyl pyrrolidone) is called for short PVP, is a kind of non-ionic macromolecule compound, is most characteristic in the N vinylamide polymer, and is studied the darkest, fine chemicals kind widely.Nonionic, cation, anion 3 big classes have been developed at present, technical grade, pharmaceutical grade, 3 kinds of specifications of food stage, relative molecular mass to the homopolymer more than 1,000,000, copolymer and crosslinking series of polymers product, and obtains extensive use with its excellent particular performances from thousands of.
PVP have colloid protective effect, film property, caking property, hygroscopicity, solubilising or cohesion, but it is most characteristic as a kind of synthesizing water-solubility macromolecular compound, thereby what be subjected to that people pay attention to is its excellent solubility property and physiological compatibility.
(1) medical and health aspect
PVP has good physiology inertia, does not participate in the human body metabolism, has good biocompatibility again, and skin, mucosa, eye etc. are not formed any stimulation.PVP is widely used as the adjuvant of pharmaceutical preparation.
(2) daily cosmetics aspect
In the consumption structure of PVP, the cosmetics industry of developed country accounts for 30%～50%, and China accounts for 70%～80%.Because PVP has extremely low toxicity and physiology inertia, it is non-stimulated to skin, eyes, and the record of life-time service is arranged in field of medicaments, so it is very safe to be used for cosmetics etc.In daily cosmetics; PVP and copolymer have good dispersion and film property; PVP has the effect of protecting colloid in emulsion; can be used in fatty and the non-fatty mastic, as dispersant and the affinity agent in foam stabiliser, wave setting agent and the hair dye of the opacifier of the setting agent of style keeping liquid, hair spray and mousse, hair care agent, shampoo.In vanishing cream, sunscreen cream, depilatory, add PVP, can strengthen moistening and lubricant effect.
