| titleOfInvention | A kind of biodegradable medical sthptic sponge and preparation method thereof |
| abstract | The invention discloses a kind of biodegradable medical sthptic sponge and preparation method thereof.The preparation method of the biodegradable medical sthptic sponge, comprises the following steps：(1) after carboxymethyl chitosan being added to the water into dissolving, progress precrosslink is stood after adding propanetriol-diglycidyl-ether mixing；(2) sodium carboxymethylcellulose, polyvinyl alcohol and poloxamer are sequentially added in the obtained mixed liquor in step (1), stirs and foam, produce the biodegradable medical sthptic sponge after drying.In above-mentioned preparation method, in parts by weight, the proportioning of each raw material is as follows：Carboxymethyl chitosan：1~10 part, sodium carboxymethylcellulose：0.1~5 part, polyvinyl alcohol：0.1~5 part, propanetriol-diglycidyl-ether：0.001~2 part, poloxamer：0.1~3 part, water：100 parts.The liquid absorption of biodegradable medical sthptic sponge of the present invention is high, physical support is strong, pliability is good, anthemorrhagic speed is fast, hemolysis rate is low, nontoxic and cell growth has facilitation. |
