Abstract:
1. An electrode system for transcutaneous nerve and/or muscle stimulation, comprising: a pair of stimulating electrodes, at least one of the pair of stimulating electrodes comprising a first part of the stimulating electrode and a second part of the stimulating electrode; a first current generator connected to the pair of stimulating electrodes, the first current generator configured to generate a nerve and/or muscle stimulation current between the pair of stimulating electrodes; a first current-injecting electrode comprising a first part and a second part, the first current-injecting electrode surrounding one of the pair of stimulating electrodes such that the first part and the second part of the first current-injecting electrode is disposed between the pair of stimulating electrodes when the pair of stimulating electrodes are positioned on a skin surface and; a second current generator connected to the first current-injecting electrode and at least one of the pair of stimulation electrodes, the second current generator configured to generate an injection current between the first current-injecting electrode and the connected at least one of the pair of stimulating electrodes for making subcutaneous receptors less excitable, wherein the first current-injecting electrode and the at least one of the pair stimulating electrodes are configured for placement on a skin surface such that the injection current does not extend depthwise but instead remains at the skin surface, the first part of the stimulating electrode is surrounded by the first part of the first current-injecting electrode, the first part of the first current-injecting electrode is surrounded by the second part of the stimulating electrode, and the second part of the stimulating electrode is surrounded by the second part of the first current-injecting electrode, wherein the pair of stimulating electrodes are separated by a distance, and wherein the first current-injecting electrode is arranged at a distance from one of the stimulating electrodes that is shorter than the distance between the pair of stimulating electrodes.
