BIODEGRADABLE WOUND COATING AND METHOD FOR PREPARING BIODEGRADABLE WOUND COATING Russian patent published in 2014 - IPC A61L15/28 A61L15/20 A61L15/32 

FIELD: medicine.

SUBSTANCE: what is described is a coating in the form of a film which contains the following ingredients, wt %: low-molecular edible chitosan 5.3-5.7, glycerol 2.2-2.8, ceruloplasmin 0.06-0.08, L-asparaginic acid 0.04-0.06, a solvent with pH 5-7 - the rest. What is described is a method for preparing the coating consisting in the fact that a chitosan weigh is diluted in the solvent at 1000 mg of the weigh to 15 ml of the solvent, mixed and placed in a thermostat at a temperature of 37-42°C for 1-2 hours. The mixture is added with ceruloplasmin diluted in the solvent at 1:10 to form a homogenous hydrogel. L-asparaginic acid is diluted in the solvent pre-heated to 37-40°C and added to the mixture to provide pH of the mixture 5-7. A plasticising agent in the form of glycerol is added in the amount of 2.2-2.8% of total volume of the prepared biomass The prepared biomass is placed into containers to form a uniform layer of the coating 3-5 mm high and to form a film by drying the biomass for 18-24 hours in the thermostat at a temperature of 37-40°C.

EFFECT: wound coating provides the highest clinical effect.
