| 20090187134 | Iontophoresis Device Controlling Amounts of a Sleep-Inducing Agent and a Stimulant to be Administered and Time at Which the Drugs are Administered - An iontophoresis device includes an electric power source device, a drug administration device and a current control device. The drug administration device may include at least two or more electrode assemblies each holding an ionic drug. The drug administration device may be coupled to the electric power source device. The current control device may control current flowing to respective ones of the electrode assemblies. An amount of the ionic drug is releasable from each of the electrode assemblies at a defined time when transdermally administered to an organism in accordance with the current flowing from the current control device, wherein at least one of the two or more electrode assemblies holds a sleep-inducing agent as the ionic drug, and at least another one of the two or more electrode assemblies holds a stimulant as the ionic drug. | 07-23-2009 |
| 20090216175 | Transdermal Administration Device and Method of Controlling the Same - To provide a transdermal administration device capable of increasing the speed at which a drug is transferred into a skin and the amount of the drug to be transferred into the skin. A transdermal administration device is constituted by: an electrode supplied with a voltage of a first conductivity type; an electrolyte solution holding portion holding an electrolyte solution energized by the electrode; and a bipolar membrane that is placed on the front surface side of the electrolyte solution holding portion, and is composed of a first ion exchange membrane that selectively passes an ion of the first conductivity type and a second ion exchange membrane that selectively passes an ion of a second conductivity type. | 08-27-2009 |
| 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 |
| 20100016781 | Iontophoresis device selecting drug to be administered on the basis of information form sensor - An iontophoresis device including an electric power source. A first electrode assembly is electrically coupled to the electric power source to transdermally administer an ionic drug to an organism via iontophoresis while a second electrode assembly is electrically coupled to the electric power source as a counter electrode to the first electrode assembly. A sensor may be positioned proximate an internal or external portion of the organism and operable to determine information used to select and deliver the ionic drug to the organism. | 01-21-2010 |
