Hyaluronic-acid-containing hemostatic gauze and preparation method thereof

Abstract

The invention discloses hyaluronic-acid-containing hemostatic gauze. The hyaluronic-acid-containing hemostatic gauze is characterized by being prepared from the following raw materials in parts by weight: 2-4 parts of folium artemisiae argyi, 1-2 parts of calendula, 2-4 parts of tremella, 1-2 parts of peach gum, 8-12 parts of gelatin, 0.3-0.5 part of hyaluronic acid, 2-4 parts of sodium alginate, 3-5 parts of sodium carboxymethylcellulose, 0.3-0.5 part of sodium dihydrogen phosphate, 0.2-0.4 part of ethylene diamine tetraacetic acid, 0.1-0.2 part of polyvinylpyrrolidone, 1-2 parts of auxiliary materials, and 200-250 parts of water. The soluble hemostatic gauze disclosed by the invention is collaboratively prepared from natural high polymer materials, is good in hemostatic function, is easy absorbed by human body, is good in biocompatibility, and is free from toxic and side effects; the soluble hemostatic gauze is capable of astringing to stop bleeding, and inhibiting bacteria and resisting inflammation by extracting and compounding the natural effective ingredients of calendula and folium artemisiae argyi, has a controlled-release function, effectively prolongs the action time, and achieves a better use effect.

Description

technical field

[0001] The invention relates to the field of medicine, in particular to a hemostatic gauze containing hyaluronic acid 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. Traditional hemostatic gauze is generally made of cotton, linen, etc., which has poor antibacterial and antibacterial ability, gauze fibers are easy to cause foreign body rejection and affect wound healing, and are easy to adhere to wound tissue during use, causing secondary damage. The generated waste has a complicated treatment process and is easy to pollute the environment.
