Blocking material capable of stopping bleeding, preparation method thereof, and blocking product capable of stopping bleeding

Abstract

The invention provides a blocking material capable of stopping bleeding, a preparation method thereof, and a blocking product capable of stopping bleeding. The blocking material comprises a matrix, and a wet state adhesive layer which is arranged on at least one surface of the matrix; the matrix comprises nonwoven fiber filament; the linear density of the nonwoven fiber filament ranges from 0.5dtex to 5dtex, and the carboxylation degree ranges from 12 to 25%; the wet state adhesive layer is obtained through contact of at least one surface with an adhesive solution; the adhesive solution contains an amino compound and a buffer solution; the amino compound is dissolved in the buffer solution. The blocking material possesses excellent adhesion performance and water adsorption performance, iscapable of realizing effective adhesion with organism surfaces or parenchyma organ surfaces, and can be degraded and absorbed; deposition in internal organs is avoided; internal organs function damageis not caused; and the blocking material is safe to be used for stopping bleeding.

Description

technical field [0001] The invention relates to a hemostatic plugging material, a preparation method thereof and a hemostatic plugging product, belonging to the field of medical implant materials. Background technique [0002] Hemostatic blockage is an important link in the operation of various departments in the hospital, and plays a considerable role in the success of the operation and the safety of the patient. Effective hemostasis is the key to relieving patients' suffering and reducing mortality, and rapid and effective hemostasis has become the focus of solving this problem. In daily life, it is inevitable to encounter damage to body tissues caused by various unexpected accidents and disasters. [0003] At present, common hemostatic materials include microporous inorganic materials (zeolites), microporous starch, fibrin glue, gelatin sponge, carboxymethylcellulose soluble hemostatic gauze, α-cyanoacrylate tissue glue, etc. Although there is a good hemostatic effect, ...

AI Technical Summary

Problems solved by technology

[0008] Based on the above-mentioned technical problems in the prior art, for example: the adhesion is poor, and it is easy to fall off from the wound; the temperature around the wound is raised to cause a burn wound, which is difficult to heal; the speed of hemostasis and the amount of hemostasis are still not enough for a large number of rapid bleeding Requirements for emergency treatment; poor water absorption performance, etc.
