However, due to the serious destruction of traditional Chinese medicine resources in recent years, the yield of Sophora flavescens root as a traditional medicinal part can no longer meet the clinical needs. Therefore, it has become a general trend to study the antibacterial activity of other parts of Sophora flavescens and its preparations.

Abstract
The present invention discloses a finishing method of absorbent cotton gauze to achieve sustained-release bacteriostatic performance and a high liquid absorption rate. The method includes the steps ofheating absorbent cotton gauze with a sodium percarbonate solution through a water bath, neutralizing the absorbent cotton gauze with a hydrochloric acid solution after oxidation treatment, and fullywashing and drying the absorbent cotton gauze to obtain the absorbent cotton gauze which is subjected to oxidation treatment; dissolving chitosan in an acetic acid solution, magnetically stirring themixture uniformly, immersing the absorbent cotton gauze which is subjected to oxidation treatment into the mixture, and then performing drying to obtain the absorbent cotton gauze treated with chitosan; after heating of Vaseline, mixing the heated Vaseline with paraffin oil and radix sophorae flavescentis seed flavonoid sustained-release pellets, performing sterilization at the high pressure, immersing the oxidized absorbent cotton gauze treated with the chitosan into the mixture, then taking out the cotton gauze for draining, and obtaining the sustained-release bacteriostatic absorbent cotton gauze through ethylene oxide treatment; uniformly mixing and heating a polyvinyl alcohol water solution, an absorbent material and oxidized-graphene-modified superabsorbent resin, immersing the sustained-release bacteriostatic absorbent cotton gauze into the mixture, then taking out the cotton gauze, putting it on a printed scraper plate, and performing drying to obtain the sustained-release bacteriostatic absorbent cotton gauze with the high liquid absorption rate after a scraper moves back and forth three times for scraping.
Description
technical field [0001] The invention belongs to the field of gauze, in particular to a slow-release antibacterial-high liquid absorption finishing method for absorbent cotton gauze. Background technique [0002] Gauze, as a main medical dressing, is widely used in wounds. Traditional cotton gauze cannot effectively absorb the exudate from the wound surface, and the hemostasis is slow, which is not conducive to wound healing. In addition, due to the limited liquid absorption capacity of gauze, frequent replacement of gauze is required, which increases the workload of medical staff. Therefore, it is very important to prepare a gauze with high liquid absorption performance. [0003] Sophora flavescens is a traditional Chinese medicine with significant antibacterial activity. It can replace antibiotics to a certain extent in the clinical treatment of bacterial infectious diseases. It has the advantages of small side effects and is not easy to produce drug resistance. The rese...
