FIELD: chemical or physical processes.
SUBSTANCE: group of inventions discloses a polymer composition for facilitating and maintaining haemostasis and a method of producing said composition. Composition is characterized by that it contains from 1 to 5 wt % sodium alginate 5 to 40 wt % chitosan and from 50 to 94 wt % water, where the polymer composition is a colloidal gel with chitosan solid particles dispersed in a solution of sodium alginate in water. Method involves mixing sodium alginate with water and further adding chitosan to obtain a polymer composition. Solid gel particles enable to mechanically prevent the fluid flowing through the gel, as well as improving adhesion/aggregation of cells, providing effectiveness in relieving and maintaining haemostasis.
EFFECT: high-efficiency haemostatic adhesive polymer frame is disclosed.
