    • An iontophoresis device useful for administering an ionic drug by iontophoresis has an iontophoresis electrode section (active electrode section) and a ground electrode section (inactive electrode section) both of which are to be connected to a power source. The iontophoresis device includes elements (members) of both of the electrode sections are all formed of membrane bodies, and includes ion exchange membranes different in ion selectivity, one being selective to ions of the same species as charged ions of the ionic drug and the other to ions different in species from the charged ions of the ionic drug that are arranged in the iontophoresis electrode section, and at least an ion exchange membrane selective to ions opposite to the charged ions of the ionic drug is arranged in the ground electrode section. The iontophoresis device can administer the ionic drug stably over a long period of time at high transport efficiency.
    • 用于通过离子电渗法施用离子药物的离子电渗疗装置具有两个要连接到电源的离子电渗电极部分(有源电极部分)和接地电极部分(无电极部分)。 离子电渗装置包括两个电极部分的元件(构件)均由膜体形成,并且包括离子选择性不同的离子交换膜,一个对离子与离子药物的带电离子相同的离子的离子选择性 与离子电泳电极部中配置的离子性药物的带电离子不同的离子,并且至少对离子药物的与带电离子相反的离子选择性的离子交换膜配置在接地电极部。 离子电渗装置可以在高运输效率下长时间稳定地施用离子药物。
