  • Patent number: 8222622
    Abstract: A DC power supply 1 is connected with the DC-type high voltage generator 2 that boosts the power supply. A negative output terminal 3 and a positive output terminal 6 of the generator 2 are respectively connected to a cathode electrode 5 and an anode electrode 7. A dielectric sheet 4 with appropriate relative permittivity and certain range of volume resistivity is closely attached on the cathode electrode surface opposed to the anode electrode. The cathode electrode 5 together with the dielectric sheet 4 constitutes a DC-type dielectric barrier electrode 9. The power supply 1 and the generator 2 are disposed on an upper surface of a belt-type attachment 15, and the discharge electrode 9 and the anode electrode 7 are disposed on the lower surface thereof. The electrodes 9 and 7 become opposed to each other upon wrapping the attachment 15 around the affected part of a subject.

  • Publication number: 20110171626
    Abstract: An infusion solution bag 11 filled with a physiological saline and an infusion pump 12 are connected to an electron irradiation apparatus 13. The electron irradiation apparatus 13 is connected to a DC-type high voltage generator 2 connected with a DC power supply 1. Using the electron irradiation apparatus 13, an electron-irradiated physiological saline is prepared and administered intravenously to a human body 14. The electron irradiation apparatus 13 has a flow path 16 for the physiological saline inside the cylindrical column. In a first side of the column, a dielectric material 19 is closely attached to a cathode electrode 20. In a second side of the column, a conductive material pad 21 is closely attached to an anode electrode 22. Third and fourth sides between the electrodes 20 and 22 are composed of an insulation material 23 insulating each of the electrodes.
