Abstract

The invention discloses an absorbable medical hemostatic material and a preparation process thereof. The hemostatic material is prepared from the following components: fish scale collagen protein, maltodextrin, oligomannuronate, potassium alginate, D-threitol, polycaprolactone, 0.7 mol / L radix angelicae and alcohol extract, oxaloacetic acid, carboxyl glucan, gamma-polyglutamic acid, glycine ethyl ester, sodium D-glucuronate, microcrystalline cellulose 101, L-pentaguluronic acid pentasodium salt, citric acid and distilled water. The hemostatic material provided by the invention can stop bleeding quickly, is high in hemostasis rate, is higher in degrading speed in vivo, is non-toxic and high in biocompatibility, does not have immunoreactions, is high in capacity of healing and recovering a wound, can be used safely and reliably, and has a good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to an absorbable medical hemostatic material and a preparation process thereof. Background technique [0002] Rapid and effective hemostasis is an important link in clinical operations and first aid for war wounds. At present, there are as many as several hundred tons of various hemostatic drugs used clinically in my country every year, and the trend is increasing year by year. Traditional wound hemostatic materials are mostly non-absorbable. Although they have a certain hemostatic effect, they are prone to infection and other complications in the surgical area. In recent years, research on absorbable hemostatic materials has attracted extensive attention from various countries. [0003] An ideal absorbable hemostatic material must not only have good hemostatic properties, be degradable in vivo, not affect tissue healing, and not increase the probability of i...
