Absorbable composite styptic powder and preparation method thereof

Abstract

The invention discloses absorbable composite styptic powder which is prepared from the following raw materials in parts by weight: 10-30 parts of carboxymethyl chitosan, 10-30 parts of sodium alginate, 10-20 parts of sodium carboxymethylcellulose, 15-50 parts of sodium starch glycolate, 30-60 parts of mannitol, 1-5 parts of calcium chloride and 2,000-4,000 parts of distilled water. The absorbable composite styptic powder disclosed by the invention does not contain any toxic chemical agent and has the functions of inhibiting bacteria, promoting wound healing and inhibiting scar formation; after the absorbable composite styptic powder is scattered and applied, moisture in blood can be uniformly and quickly absorbed by the absorbable composite styptic powder, and a 'white core' is not formed, therefore, the absorbable composite styptic powder is styptic powder which is convenient to use, high in efficiency and extremely good in styptic effect and has no side effect.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to an absorbable compound hemostatic powder and a preparation method thereof. Background technique [0002] With the continuous advancement of medical technology, new medical materials and related technologies have been well developed. Among them, the development and improvement of hemostatic materials are conducive to improving the problems of surgical bleeding and bleeding, which is of great significance and has become a hot research topic in the field of medicine. [0003] War wounds, trauma, emergency animal husbandry and surgical operations will all cause bleeding. This problem needs to be solved urgently. The normal human body has the function of hemostasis. Slow and small amount of bleeding can stop bleeding by relying on its own function. The body cannot stop the bleeding by itself, nor can it only rely on ordinary hemostatic bandages to stop the bleeding. If the patient loses too m...

AI Technical Summary

Problems solved by technology

[0004] At present, the clinically used hemostatic materials mainly include fibrin glue, collagen, gelatin sponge and cellulose hemostatic materials. These materials have achieved good results in animal experiments and clinical applications, but there are also some shortcomings: The raw material is derived from animal tissue, which is a foreign protein, which is prone to rejection and has potential sensitization; gelatin absorbs slowly, generally more than 4 weeks, which will increase the risk of wound infection; cellulose, the human body lacks enzymes to degrade it , the degradation time is long, which may bring side effects such as infection to the patient

[0009] 1. Modified starch-based hemostatic powder requires the use of a variety of toxic chemical reagents, which has potential residual toxicity problems;

[0010] 2. Collagen-based hemostatic powder is derived from animals, is a foreign protein, is prone to repellency, has potential sensitization, and absorbs slowly, generally taking more than 4 weeks;

[0011] 3. Most hemostatic powders only have hemostatic effect, no antibacterial effect, promote wound healing, and inhibit scar formation
