Abstract

The invention discloses a fluid hemostatic adhesive as well as a preparation method and application thereof. The fluid hemostatic adhesive comprises a hemostatic effective component and a fluid matrix, wherein the hemostatic effective component is prepared from a component A, a component B and a component C; the component A is gelatin, the component B is sodium glycero-phosphate, and the componentC is polylysine and / or polyethyleneimine; a mass ratio of the component A to the component B to the component C is (1 to 6):(1 to 2):1. The fluid hemostatic adhesive provided by the invention can bestored under a fluid state and requires not to be mixed before using, the operation is simple and convenient, the operation time is greatly shortened, and rapid gelatinization can be realized after the fluid hemostatic adhesive is applied to a human body; meanwhile, the content of an assistant in the fluid hemostatic adhesive is low, and good fluidity and a good hemostatic effect are obtained; further, modified grafting treatment is carried out on the gelatin, so that the strength of the fluid hemostatic adhesive is improved, the adhesion between the fluid hemostatic adhesive and a wound can be remarkably improved, and the hemostatic effect can be further improved.

Description

technical field [0001] The invention relates to the field of hemostatic materials, in particular to a fluid hemostatic glue and its preparation method and application. Background technique [0002] For wounds with diffuse bleeding on uneven surfaces or hard-to-reach deep or narrow areas, commonly used sponge or yarn-like hemostatic materials are difficult to achieve sufficient wound coverage, so flowable hemostatic materials are required. The fluid hemostatic material can shape itself according to the shape of the wound to achieve full contact, and has a good effect on the hemostasis of the above-mentioned special wound. [0003] The fluid hemostatic materials currently on the market mainly include Floseal Haemostatic Matrix of Baxter Company and Surgiflo Haemostatic Matrix of Ethicon Company. Among them, Floseal HaemostaticMatrix is ​​a kit for making hemostatic gelatin paste. The gelatin paste was made by first preparing a thrombin solution and then transferring the gela...
