| 摘要 |
The present invention relates to an apparatus for supplying electric energy to biological tissue with a view to supporting different physiological processes, including different phases of healing, growth, modification of pathological states, for example deterioration in blood flow, chronic pain, fluid accumulation in tissue etc., and similarly with a view to influencing viability conditions of, for instance, tumour tissue, the apparatus essentially comprising at least two electrodes connected to a D.C. voltage source, of which one electrode is intended to be disposed in or on the biotissue which is to be supported in its physiological or pathophysiological cycle, and the other electrode is intended to be disposed in spaced-apart relationship from the biological tissue in such a position that electrically conducting circuits exist between the electrodes, the voltage source being arranged, via said electrodes, to supply current through the biotissue. For simulating the physiological healing process, the voltage source is operative to supply a current whose amplitude values alternate with time, and each maximum amplitude value is lower in absolute terms than the immediately preceding amplitude value. Finally, the alternation of the current is caused to take place several times. |
