  • Pain sensory nerve stimulation apparatus
    Patent number: 10543356
    Abstract: A pain sensory nerve stimulation apparatus includes: an electrode portion including: a first electrode, a tip end of which is adapted to be inserted into a skin; and at lease one second electrode which is disposed in a circumference of the first electrode without being electrically conductive with the first electrode, and which is adapted to be in contact with a skin; and a stimulation signal supplying unit, supplying a bipolar stimulation signal between the first electrode and the second electrode, the bipolar stimulation signal including a first waveform signal and a second waveform, the first waveform which is convex in a negative direction in the first electrode, the second waveform signal which is convex in a positive direction in the first electrode.
    Type: Grant
    Filed: February 9, 2011
    Date of Patent: January 28, 2020
    Assignees: INTER-UNIVERSITY RESEARCH INSTITUTE CORPORATION, NIHON KOHDEN CORPORATION
    Inventors: Koji Inui, Yasuyuki Takeshima, Jun Motogi, Yoshinobu Ono, Takeshi Kojima, Ryosuke Ushijima, Katsumi Nakaichi, Kazuwa Shibuya
  • Pain sensory nerve stimulation apparatus
    Patent number: 10413717
    Abstract: A pain sensory nerve stimulation apparatus includes: an electrode portion including: a first electrode, a tip end of which is adapted to be inserted into a skin; and at lease one second electrode which is disposed in a circumference of the first electrode without being electrically conductive with the first electrode, and which is adapted to be in contact with a skin; and a pulse signal supplier, supplying a pulse signal in which an electrical polarity of the first electrode is set as a anode and an electrical polarity of the second electrode is set as a cathode.
