METHOD FOR OBTAINING FIBRINOUS FILM Russian patent published in 2006 - IPC A61K35/14 A61K38/36 

FIELD: medicine, hematology.

SUBSTANCE: the present innovation deals with utilizing the wastes (clots) of human and animal blood to obtain curative preparation out of them. The method deals with isolating fibrin out of a blood clot followed by dissolving and applying it onto the surface up to fibrinous layer thickness being about 5-7 mm with subsequent drying. Moreover, isolated fibrin should be dissolved at 21-25°C in 8-10%-ammonia solution at 1 g crude fibrin/3-5 ml solution for 3-5 d, and it should be dried at an even surface pre-treated with 50%-glycerol solution at 30-40°C. The innovation enables to obtain a film out of blood clot's fibrin without applying salt in order to obtain the final product containing fibrin only.

EFFECT: higher efficiency.
