Problems solved by technology

"Journal of the Academy of Military Medical Sciences" (1993, 17 (1)) has reported the research of chitosan-norfloxacin burn dressing, and this dressing is not a pure natural material, and the synthetic drug therein has certain toxic and side effects
Moreover, the chitosan used in this type of product has undergone physical recrystallization or chemical modification with a high degree of substitution during the preparation process, which reduces the active amino group of the product, reduces the antibacterial property, and weakens the ability to control wound infection.

Embodiment 1

[0008] A dressing containing antibacterial hemostatic traditional Chinese medicine, comprising cotton base material, 0.5% glycerin, 0.5% chitosan solution and antibacterial hemostatic traditional Chinese medicine extract; glycerin, chitosan and antibacterial hemostatic traditional Chinese medicine extract are attached to the base material; the antibacterial hemostatic traditional Chinese medicine The manufacturing method of the biological dressing comprises the following steps: 1) impregnating the cotton with glycerin and chitosan solution, and drying; 2) impregnating the hemostatic traditional Chinese medicine extract, and drying to obtain the biological dressing containing antibacterial and hemostatic traditional Chinese medicine.

[0009] The biological dressing containing antibacterial and hemostatic traditional Chinese medicine uses cotton to absorb wound exudate and protect the wound. Glycerin acts as a plasticizer, making the dressing soft. Antibacterial extracts, such ...

Embodiment 2

[0010] Embodiment 2: Most of it is the same as Embodiment 1, except that the base material is gauze, 5% glycerin, and 2.5% chitosan solution.

Embodiment 3

[0011] Embodiment 3: Most of them are the same as in Embodiment 1, except that the base material is a non-woven fabric, 2% glycerin, and 1.5% chitosan solution.

[0012] Embodiment 3: Most of them are the same as in Embodiment 1, except that the base material is non-woven fabric and gauze, the gauze is attached to the top of the non-woven fabric, 4% glycerin, 1% chitosan solution.

[0013] In summary, the biological dressing containing antibacterial and hemostatic traditional Chinese medicine of the present invention uses cotton to absorb wound exudate and protect the wound. Glycerin acts as a plasticizer, making the dressing soft. Antibacterial extracts, such as Coptis chinensis and Cortex Phellodendri extracts have a good inhibitory effect on common skin infections such as Staphylococcus aureus and Pseudomonas aeruginosa, and mainly play an antibacterial role. Hemostatic extracts, such as rhubarb extracts, have a hemostatic effect. Chitosan has biological activity, can prev...

Abstract

The invention discloses a traditional Chinese medicine dressing for antibacterium and hematischesis and a production method thereof. A biological dressing prepared by taking cotton, gauze and non-woven fabrics as base materials, glycerin as a plasticizing agent and chitosan as a filmogen and dipping in a traditional Chinese medicine extracting solution for antibacterium and hematischesis can be widely used as a dressing for surfaces of wound caused by burning and hurting, has the characteristics of favorable biocompatibility, security, absorbing wound seepage, antibacterium, hematischesis, accelerating the concrescence of the wound, and the like and takes crudes as main materials.

Description

technical field [0001] The invention relates to a manufacturing method of a pure natural biological dressing containing antibacterial and hemostatic traditional Chinese medicines which can be widely applied to wounds. Background technique [0002] Wound dressings are divided into traditional dressings, biological dressings and synthetic dressings according to their material composition. Among them, biological dressings have the characteristics of good biocompatibility, safety, and quick wound healing, so they are favored by people. CN1275408 discloses the technology that extracts bioactive substance and collagen to prepare biological dressing from epithelial and dermal tissue of animal; CN1380109 has reported a kind of chitosan, collagen and calcium alginate composite sponge biological dressing and its manufacturing process; "Chinese Biomedicine Engineering Journal (1996, 15 (2)) reported that chitosan, gelatin and glycerin were used as basic raw materials, and glutaraldehy...
