Biological membrane preparation for promoting wound healing and preparation method of biological membrane preparation

Abstract

The invention belongs to the field of medicine products and particularly relates to a biological membrane preparation for promoting wound healing and a preparation method of the biological membrane preparation. The biological membrane preparation is prepared from components in parts by weight as follows: 0.20-0.75 parts of saccharomycopsis fibuligera polysaccharide extract, 10-25 parts of calciumalginate, 2-6 parts of syringin, 100-150 parts of chitosan and 50-80 parts of silk fibroin. Compared with the prior art, the biological membrane preparation for promoting wound healing has functions of rapid hemostasis and rapid healing; the components are safe and non-irritant and have the effect of repairing scars. The biological membrane preparation is low in cost, good in effect and free of side effects and belongs to natural products.

Description

technical field

[0001] The invention belongs to the field of medical products, and in particular relates to a biofilm preparation for promoting wound healing and a preparation method thereof. Background technique

[0002] The skin is an important organ of the human body and has various functions such as barrier protection, absorption and metabolism, secretion and excretion, temperature regulation, and immunity. Due to trauma, abrasions, skin ulceration and burns, etc., it may cause extensive damage to the skin, and may lead to complications that endanger human life. The wound healing process is divided into four phases: (1) Interstitial fluid exudation phase: collagen fibrous cells secrete collagen to fill the wound, and type I collagen is the main collagen for scar formation. (2) Inflammatory phase (debridement phase): it occurs within 24-48 hours and is accompanied by bacterial infection. At this time, immune cells mainly clear damaged tissues and microorganisms. (3) Pro...
