Patent number: 7502654Abstract: The invention provides an electrode device that prevents disconnection of an electrode layer effectively by reducing stress at the time when a recess is formed. An electrode device (10) has a protrusion (70), which projects upward, in the part of an outward flange section (110f), other than a recess (60) formed by molding. The protrusion (70) is arranged so as to surround an outer periphery of the recess (60). When the recess (60) is cold-pressed, the protrusion (70) prevents warp (warp waving along a peripheral direction) in the outward flange section (110f) from occurring. Consequently, the protrusion (70) also eases warp of an electrode layer (30) extending on the outward flange section (110f) and prevents disconnection of the electrode layer (30).Type: GrantFiled: June 11, 2003Date of Patent: March 10, 2009Assignee: Hisamitsu Pharmaceutical Co., Inc.Inventors: Kenji Mori, Hiroyuki Maeda, Naruhito Higo, Shuji Sato, Yasushi Fuchita, Tatsuya Ogawa, Saori Takahashi

Patent number: 7483737Abstract: This invention relates to a technology for preventing leakage of liquid from gel (70). The electrode chip (10) comprises a cup-like support (20) including a cup part (210), and a sheet-like support (30) attached with an electrode layer (40). The gel (70) in the cup part (210) delivers liquid (700) containing water confined at the time of crosslinking. The liquid (700) moves by capillarity from the gel (70) side through a narrow gap between the outer flange (220) of the cup-like support (20) and the outside part (310o) of the sheet-like support (30) in a direction away from the gel (70). Since a groove (80) exists in the vicinity of the cup part (210) and the gap is large at that part, capillarity is broken thereat.Type: GrantFiled: October 22, 2004Date of Patent: January 27, 2009Assignee: Hisamitsu Pharmaceutical Co., IncInventors: Yasushi Fuchita, Tatsuya Ogawa, Saori Takahashi, Mitsuru Kuribayashi, Naruhito Higo

Patent number: 7005784Abstract: It is an object of the invention to prevent not only cracking but also blocking of an electrode layer 20 and an electrically insulating layer 30, particularly the electrically insulating layer 30, which is formed on a base film 10. An electrode apparatus comprises a base film 10 for defining a recess 50 at the inner periphery of a bending part 500, and an electrode layer 20 and an electrically insulating layer 30 which are pattern formed on the base film 10. The electrode layer 20 crosses the bending part 500 from the inside of the recess 50 to the outside. The electrically insulating layer 30 covers the upper part of the electrode layer 20 in the vicinity of the bending part 500. A resin composition obtained by admixing a low Tg resin having a glass transition temperature equal to 25 degrees C. or lower and a high Tg resin having a higher glass transition temperature (for example, 40 degrees C. or higher) than that of the low Tg resin is used as a dielectric of the electrically insulating layer 30.Type: GrantFiled: August 27, 2003Date of Patent: February 28, 2006Assignees: Kyodo Printing Co., Ltd., Hisamitsu Pharmaceutical Co., Inc.Inventors: Tatsuya Ogawa, Saori Takahashi, Yasushi Fuchita, Kenji Mori, Naruhito Higo

Publication number: 20050113738Abstract: There is provided an electrode device for iontophoresis capable of retaining a drug in a gel state with a force just enough so as not to disturb the treatment. In order to retain the gel (70), a sheet member (50) composed of a nonwoven fabric is laminated on a base film (20) including an electrode layer (30) so as to be integrated with the base film (20). The sheet member (50) has a property for allowing the gel (70) to permeate therein. Owing to this feature, the gel (70) loaded on the sheet member (50) is retained thereon with at least a part of the gel (70) permeated therein.Type: ApplicationFiled: January 9, 2003Publication date: May 26, 2005Inventors: Yasushi Fuchita, Tatsuya Ogawa, Saori Takahashi, Takuji Oikawa, Shuji Sato, Naruhito Higo, Hiroyuki Maeda, Kenji Mori
