采用水相单凝聚法制备出烧创伤微胶囊敷料 ,壁材是明胶 ,芯材是利用超临界萃取提出的中药材成分 ,以无水乙醇作为沉降剂。微胶囊化的工艺条件是 :明胶水溶液浓度为 1 0 % ,p H为 5.6,在温度 45℃时以 1 50 0 r/ min搅拌 2 0 min,逐滴加入无水乙醇 ,至乙醇体积浓度达到 55% ,使形成胶囊化 ,降温至 5℃后 ,固化 ,离心分离干燥即得敷料 The single-coacervation method was used to prepare the burn wound microcapsule dressing, the wall material was gelatin, and the core material was made by using supercritical fluid extraction, with anhydrous ethanol as the sedimentation agent. The conditions of microencapsulation are as follows: the concentration of gelatin aqueous solution is 10%, p H is 5.6, and the mixture is stirred at 1 50 0 r / min for 20 min at a temperature of 45 ° C. The absolute ethanol is added dropwise until the ethanol concentration reaches 55%, so that the formation of encapsulation, cooling to 5 ℃, curing, centrifugal separation and drying dressing
