    • An apparatus and method is described for applying epidermal growth factor (EGF) for achieving healing enhancement at a wound site. The human source of epidermal growth factor, designated as hEGF, is applied from the synthetic resin matrix system of this invention, and which comprises a polymer, such as poly(2-hydroxyl ethyl methyl methacrylate), referred to as PHEMA, an organic solvent, such as polyethylene glycol (PEG), and a hydrogen binding plasticizer, such as dimethylsulfoxide (DMSO). The plasticizer regulates the set-up time of the synthetic resin, so that the more plasticizer present, the shorter the set-up time. The dressing, once formed, and having the healing enhancer contained therein, may be sealed within various backing sheets, in order to preserve its aseptic condition. When ready for use, one of the backing sheets may be peeled away to expose the resin pad with the emobodied healing enhancer, ready for application to the wound site.
    • 描述了一种用于在伤口部位应用表皮生长因子(EGF)用于实现愈合增强的装置和方法。 称为hEGF的人表皮生长因子来源于本发明的合成树脂基质体系,其包含聚合物,例如聚(2-羟乙基甲基丙烯酸甲酯),称为PHEMA,有机溶剂 ,例如聚乙二醇(PEG)和氢结合增塑剂如二甲基亚砜(DMSO)。 增塑剂调节合成树脂的安装时间,使得存在的增塑剂越多,安装时间越短。 一旦形成并且其中含有愈合增强剂的敷料可以被密封在各种背衬片内,以便保持其无菌状态。 当准备使用时,其中一个背衬片可能被剥离,以暴露树脂垫与表面的愈合增强剂,准备应用于伤口部位。
