Patent number: 7567238Abstract: A medical treatment support system has operations A to G on a display screen to easily handle respective data on a sheet. Operation A facilitates the browsing of a large amount of data. Operations B and C allow the user to easily copy and move data. Operation D is a scale function to facilitate measurement. Using operation E, the operator can easily divide an area into segments only by drawing a horizontal line. Operation F is used to change a display angle of image data displayed on the screen. Operation G allows the user to browse respective data classified for each sheet label. The new functions of the single-unit input/output pen-tablet device can be intuitively operated by a user not versed in the functions. This consequently mitigates the load of complex input operation which interrupts thinking of the user and which hinders diagnosis mitigated in medical treatment.Type: GrantFiled: November 21, 2001Date of Patent: July 28, 2009Assignee: NEC CorporationInventors: Mamiko Sugimoto, Takeo Igarashi, Kazuo Nakazawa, Takashi Ashihara

Publication number: 20080195161Abstract: [PROBLEMS] To prevent ventricular fibrillation. [MEANS FOR SOLVING PROBLEMS] A rectangular base material (10) is sewn to the epicardium surface of a left ventricle (38). Four cooling Peltier elements (12) are provided at the center of the base material (10), and temperature-detecting thermistors (18) are provided at part of their peripheries. A plurality of circular, flat potential sensors/energizing electrodes (14) for detecting the surface potential of the heart are arranged in a lattice form on the surface of the base material (10) at almost equal intervals. The potential sensors/energizing electrodes (14) are energizing electrodes for delivering a pulse voltage/current to the heart. When a rapid ventricular rate is detected, these Peltier elements (12) are energized to cool the heart.Type: ApplicationFiled: April 11, 2006Publication date: August 14, 2008Inventors: Ichiro Sakuma, Itsuo Kodama, Kaichiro Kamiya, Haruo Honjo, Masatoshi Yamazaki, Takashi Ashihara, Kazuo Nakazawa
