    • A delivery mechanism and device for the passive periodic release of a drug or an active ingredient which avoids the need for external power sources and/or electronic controllers. By taking advantage of oscillating chemical systems, one can change the state, i.e. the pH, of a solution, a drug, enhancer or solubilizer resulting in oscillating the ability of an active ingredient to be delivered transdermally. The pH of a solution can be oscillated over a range of pH values from 2 to 10 by the reduction and oxidation (redox) reactions of salts, such as permanganates, iodates, sulfates, chlorates, or bromates. Upon activation, the delivery system conditions begin to oscillate and with it, the delivery of the active agent oscillates.
    • 用于药物或活性成分的被动定期释放的递送机制和装置,其避免需要外部电源和/或电子控制器。 通过利用振荡化学体系,可以改变溶液,药物,增强剂或增溶剂的状态,即pH,导致活性成分经皮递送的能力的振荡。 通过盐,如高锰酸盐,碘酸盐,硫酸盐,氯酸盐或溴酸盐的还原和氧化(氧化还原)反应,溶液的pH可以在2至10的pH范围内振荡。 在激活时,递送系统条件开始振荡并且随之而起,活性剂的递送振荡。
