Preparation method of biological dressing for treating bedsores

Abstract

The invention discloses a preparation method of a biological dressing for treating bedsores. According to the preparation method, raw materials are weighed in parts by weight, put into a reactor and subjected to ultrasonic high-speed dispersion; the dispersed mixture is poured on to a membrane preparation mold, scrapped to be flat and sufficiently dried, the mold is removed, and a medicine storage layer is prepared; finally, the prepared medicine storage layer and base cloth are bonded and composited through a binder, and the bonded composite material is punched with a dense needling micropore forming machine; the punched dense composite material is cut to be in a required shape, sealed and sterilized, and the biological dressing is prepared. The biological dressing prepared with the method adopts a traditional Chinese medicine formula, has little irritation, is free of toxic and side effects, has good biological compatibility, good antiseptic, anti-inflammation and hemostatic effects, high water retention and good tensile strength and tear strength, prevents seepage from overflowing, promotes formation of granulation tissue and epithelial tissue, promotes healing and recovery of skin tissue and has good treatment effect on bleeding, swelling, pain and the like caused by bedsores, and bedsores are not prone to relapse.

Description

technical field [0001] The invention belongs to the field of new medical biological materials, and relates to a preparation method of a biological dressing for treating bedsores. technical background [0002] Bed sores, also known as pressure ulcers or pressure sores, are one of the common complications of internal medicine. They are soft tissue necrosis caused by nerve and blood circulation disorders, local tissue continuous ischemia, and malnutrition. The complex pathological process caused by the effect is a very intractable disease. Once it occurs, the course of treatment is long and it is easy to relapse, which can cause damage from the epidermis to subcutaneous tissue, muscles, and even bones and joints, bringing great pain to patients. , Severe cases can be secondary infection, causing sepsis and leading to death. my country has a large population, many bedridden patients, and the incidence of bedsores has always been at a high value. For bedsore treatment, a lot of...
