Problems solved by technology

[0002] At present, most medical dressings are dressings containing bioactive glass. Bioactive glass has good bioactivity and biocompatibility, can activate the expression of genes related to wound healing, promote the proliferation and differentiation of fibroblasts, and accelerate the growth of blood vessels. generation, promote the growth of granulation tissue, promote the repair and regeneration of hard and soft tissues, and promote wound healing. reaction, causing a rapid increase in the local PH value, and its PH value can reach 13, forming a strong alkaline, with a certain degree of cytotoxicity, many patients will cause instant pain due to stimulation, and bring certain pain to the patient during use

Abstract

A self-derived regenerative repair ointment for wound surface, characterized in that it is composed of the following raw materials in parts by weight: 10-40 parts of regenerative medical materials, 5-20 parts of polyethylene glycol 4000, 30-80 parts of polyethylene glycol 400 5-25 parts of glycerin, 0.5-3 parts of medical-grade vitamin E oil, by mixing regenerative medicine materials, polyethylene glycol, glycerin and medical-grade vitamin E oil in a specific way, it can reach the guiding cell , extracellular matrix, blood vessels and other tissues crawling and replacing in an orderly manner, accelerate wound healing, repair the nervous system of the wound synchronously, realize the orderly growth of new tissue fiber layers, regenerate capillaries and hair follicles, and realize the endogenous tissue of the wound Regenerate and repair, inhibit scar formation. At the same time, the pH value of the mixture is 7.3-7.8, which is relatively close to the pH value of the human body. It is less irritating to the human body during use, thereby reducing the pain of patients.

Description

technical field [0001] The invention relates to the technical field of medicine for external use, in particular to an ointment for self-generating regeneration and repair of wound tissue and a preparation method thereof. Background technique [0002] At present, most medical dressings are dressings containing bioactive glass. Bioactive glass has good bioactivity and biocompatibility, can activate the expression of genes related to wound healing, promote the proliferation and differentiation of fibroblasts, and accelerate the growth of blood vessels. generation, promote the growth of granulation tissue, promote the repair and regeneration of hard and soft tissues, and promote wound healing. The reaction causes the local PH value to increase rapidly, and its PH value can reach 13, forming a strong alkalinity and having certain cytotoxicity. Many patients will cause instant severe pain due to the stimulation, which will bring certain pain to the patient during use. Contents o...
