Problems solved by technology

[0008] These technologies have the following technical defects: one, they all use propellant aerosols including propane, butane or isobutane, halogenated hydrocarbons, two, there are many kinds of medical dressings added, and the manufacturing process is complicated; three, although chitosan Sugar is the main matrix, but other antibacterial ingredients are added, such as Yujiexin, nano silver, borneol, menthol and other ingredients
[0010] The purpose of the present invention is to overcome the shortcoming that exists in the prior art, solve the problems such as lacking pure chitosan environmental protection, high-efficiency foaming agent, complicated production method at present, propose a kind of preparation method of modified chitosan antibacterial foaming agent, obtain The foam agent has a fine foam structure, good broad-spectrum antibacterial effect, can promote the recovery of lesion cells, and the preparation and application methods are simple, and can be conveniently used in the treatment and nursing of various vaginitis in clinical gynecology.

Abstract

The invention relates to an antibacterial modified chitosan foaming agent and a preparation method thereof. The preparation method of the antibacterial modified chitosan foaming agent comprises the steps of preparing modified chitosan, extracting white tea, preparing a complex solution containing chitosan, preparing a corn protein complex solution and preparing an antibacterial modified chitosan foaming agent. The antibacterial modified chitosan foaming agent has antibacterial ability more than 99% on staphylococcus aureus, escherichia coli, streptococcus, candida albicans or pseudomonas aeruginosa and shows good bacteriostatic ability. The antibacterial modified chitosan foaming agent can be applied to treatment on bacterial vaginitis, colpomycosis and mixed vaginitis and can be widely applied.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of medical drugs. More specifically, the present invention relates to a kind of antibacterial modified chitosan foam agent, also relate to the preparation method of described antibacterial modified chitosan foam agent [0003] 【Background technique】 [0004] Vaginitis is a common inflammation of female reproductive organs. Among married women, more than half of the population suffers from different degrees of vaginitis. Clinically, vaginitis can be divided into more than ten types, including bacterial vaginosis, trichomonas Vaginitis, candidal vaginitis, senile vaginitis, infantile vaginitis, candida vaginitis, viral HSV, HPv vaginitis, gonococcal vaginitis, desquamative vaginitis, non-specific vaginitis , tuberculous vaginitis, drug-induced vaginitis, radiation vaginitis, acute vaginal ulcer, allergic vaginitis, chronic vaginitis, burning insect vaginitis and mixed vaginitis, etc., are relatively c...
