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 embodied healing enhancer, ready for application to the wound site.
本发明描述了一种应用表皮生长因子(EGF)以增强伤口愈合的设备和方法。本发明的合成树脂基质系统含有一种聚合物,如聚(2-羟基乙基甲基丙烯酸甲酯),简称 PHEMA;一种有机溶剂,如聚乙二醇(PEG);以及一种氢结合增塑剂,如二甲基亚砜(DMSO)。增塑剂可以调节合成树脂的固化时间,因此增塑剂越多,固化时间越短。敷料一旦成型并含有愈合增强剂,就可以密封在各种衬垫片中,以保持其无菌状态。当准备使用时,可以剥开其中一块背板,露出含有愈合增强剂的树脂垫,准备用于伤口部位。
