| titleOfInvention | A kind of preparation method and applications of antibacterial anti hemorrhagic chitosan |
| abstract | The invention discloses a kind of preparation methods of antibacterial anti hemorrhagic chitosan: cation reagent solution being added drop-wise in epoxy agent solution, reaction temperature is controlled at 25-90 DEG C, reacts 2-24h, be evaporated under reduced pressure after reaction, obtain quaternizing agent；In a solvent by quaternizing agent dissolution, quaternizing agent solution is made；It adds chitosan into aqueous slkali, step S1 is then added, quaternizing agent solution is made, be stirred to react, obtain antibacterial chitosan after crude product washing, drying.The invention also discloses its applications.Chitosan anti-bacteria styptic sponge produced by the present invention measures staphylococcus aureus Yi Jun Shuai≤98% according to GB/T20944.3-2008 standard, and Escherichia coli Yi Jun Shuai≤90% shows that sponge has antibacterial effect；The haemostatic effect of manufactured antibacterial anti hemorrhagic sponge is also excellent, Jian≤60 second Shi of stopping blooding；It is biodegradable and using antibacterial anti hemorrhagic sponge made from chitosan without obvious cytotoxicity. |
