    • An iontophoresis device, which can ensure the long-term stability of drugs and which can be easily assembled when used, is provided. A donor electrode-printed portion (6) is placed on one side of a backing layer (4), and a reference electrode-printed portion (7) is placed on the other side. Both printed parts are connected to a current generating part (Ia) through a connector (Id). A drug support film (14) is joined to a drug-dissolving portion (11), and a cup-like shaped protective cover (12), which covers the drug support film (14), is removed before the device is used. The exposed drug support film (14) is attached to the skin of a user, and the device is driven by turning on a power supply of the current-generating portion (Ia).
    • 一种离子电渗疗法装置,其可以确保药物的长期稳定性,并且在使用时可以容易地组装。 供体电极印刷部分(6)放置在背衬层(4)的一侧上,另一侧放置参考电极印刷部分(7)。 两个印刷部分通过连接器(Id)连接到电流产生部分(Ia)。 将药物保护膜(14)与药物溶解部(11)接合,在使用该装置之前,除去覆盖药物保护膜(14)的杯状保护罩(12)。 暴露的药物支撑膜(14)附接到使用者的皮肤,并且通过接通电流产生部分(1a)的电源来驱动该装置。

    • The present invention provides an iontophoresis device and an energization method whereby a prostaglandin can be effectively and continuously administered via a skin or mucosa. The iontophoresis device comprises the first electrode structure (31); the second electrode structure (32); and a power supply (33) electrically connected between the first and the second electrode structures (31), (32). At least one of the first and the second electrode structures contains a prostaglandin and also stabilizing means for inhibiting hydrolysis of the prostaglandin during storage. The power supply (33) is equipped with constant current supplying means and, when both electrode structures contain a prostaglandin, also polarity inverting means. Output current from the power supply may allow the prostaglandin to be delivered to a skin or mucosa.
    • 本发明提供了一种离子电渗疗法装置和通电方法,其中前列腺素可通过皮肤或粘膜有效且连续地施用。 离子电渗装置包括第一电极结构(31); 第二电极结构(32); 和电连接在第一和第二电极结构(31),(32)之间的电源(33)。 第一和第二电极结构中的至少一个包含前列腺素以及用于在储存期间抑制前列腺素水解的稳定手段。 电源(33)配备有恒流供给装置,并且当两个电极结构都包含前列腺素时,还具有极性反转装置。 来自电源的输出电流可允许将前列腺素输送至皮肤或粘膜。
