|20100100031||IONTOPHORESIS DEVICE - The present invention provides an iontophoresis device with high administration efficient of a drug. An iontophoresis device, including an active electrode structure including: an electrode to which a positive electrical potential is applied; a drug holding part for holding a drug solution containing positively charged drug ions, the drug holding part being placed on a front side of the electrode; a cellulose-based resin film placed on a front side of the drug holding part or a complex film composed of a cation exchange membrane and a cellulose-based resin film placed on a front side of the cation exchange membrane, the complex film being placed on a front side of the drug holding part, in which the drug ions are administered through the cellulose-based resin film.||04-22-2010|
|20090299265||Electrode Assembly for Iontophoresis Having Shape-Memory Separator and Iontophoresis Device Using the Same - An electrode assembly for iontophoresis including an electrode coupled to an electric power source device having a same polarity as that of the ionic drug in the electrode assembly, an electrolyte solution holding portion holding an electrolyte solution by being impregnated with the electrolyte solution, the electrolyte solution holding portion being placed adjacent to the electrode, a first ion exchange membrane operable to substantially pass ions having a polarity that is same as a polarity of the ionic drug and substantially block ions having a polarity that is opposite the polarity of the ionic drug, the first ion exchange membrane being placed adjacent to the electrolyte solution holding portion, a drug solution holding portion holding the ionic drug by being impregnated with the ionic drug, the drug solution holding portion being placed adjacent to the first ion exchange membrane, a second ion exchange membrane operable to substantially pass ions having a polarity that is opposite the polarity of the ionic drug and substantially block ions having a polarity that is the same as the polarity of the ionic drug, the second ion exchange membrane being placed adjacent to the drug solution holding portion, and a shape-memory separator capable of being transformed between a first and a second configuration to respectively allow passage of a substance and blocking of the substance, the shape-memory separator placed adjacent to at least one surface of the first ion exchange membrane.||12-03-2009|
|20090299264||Electrode Assembly for Dry Type Iontophoresis - An iontophoresis device capable of stably holding a drug for a long time period and of transdermally administering the drug at a high transport number during use. The iontophoresis device includes a drug holding portion to store the ionic drug in a dry state and at least an aqueous medium holding portion to store an aqueous medium. The drug holding portion exhibiting ion conductivity in response to a needle inserted into the aqueous medium holding portion from outside the electrode assembly such that the drug holding portion is supplied with the aqueous medium during use and the ionic drug dissolves in the aqueous medium.||12-03-2009|
|20090062721||IONTOPHORESIS DEVICE AND METHOD OF MANUFACTURING THE SAME - An iontophoresis device including an electrode assembly which holds a drug solution containing a salt of a first drug with an acid dissolved therein and has a polarizable electrode to be in contact with the drug solution, in which the polarizable electrode to which a second drug of the same kind as that of the first drug is adsorbed. A method may include adsorbing the second drug to the polarizable electrode; and then bringing the drug solution into contact with the polarizable electrode. As a result, the iontophoresis device is capable of suppressing a change in the pH value of the drug solution in the case where the drug solution containing the salt of the first drug with the acid dissolved is held in contact with the polarizable electrode.||03-05-2009|
