    • In one example, the present invention is directed to a wound-healing patch including a flexible substrate, at least one wound electrode, at least one guard electrode and at least one return electrode. The guard electrode is positioned between the wound and return electrodes in the electrical path of current traveling between the return and wound electrodes on the surface of the skin, sinking the surface current and force the wound current to travel deeper into the tissue. In the invention, the wound electrode(s) is positioned on a portion of the flexible substrate designed to be placed over wounded tissue and the return electrode is positioned on a portion of the substrate substantially surrounding the wound and guard electrodes and is designed to be placed over healthy tissue.
    • 在一个实例中,本发明涉及包括柔性基底,至少一个缠绕电极,至少一个保护电极和至少一个返回电极的伤口愈合贴片。 保护电极位于卷绕和返回电极之间的电路中,电流在皮肤表面的返回电极和缠绕电极之间传播,从而降低表面电流,并迫使伤口电流更深地进入组织。 在本发明中,卷绕电极位于设计成放置在受伤组织上的柔性基板的一部分上,并且返回电极位于基本上围绕伤口和保护电极的基底的一部分上,并被设计为 放在健康的组织上。
