  • Patent number: 10206604
    Abstract: The present invention relates to the field of electrotherapy and measuring by means of electric cur-rents for diagnostic purposes, and more particularly to an electrode arrangement for facilitating wound healing, a method for measuring wound healing and a wound dressing having an electrode arrangement. A wound dressing according is described which includes at least two impedance reference electrodes, a frame like counter-electrode and stimulation electrodes in a form of an array; and a bioadhesive affinity layer surrounding the stimulation electrodes; said wound dressing being suited for applying on top of the wound so that the stimulation electrode array is on the wound area, and that the at least two impedance reference electrodes and the frame like counter-electrode are suited for placing in contact with the healthy skin surrounding the wound area; which electrodes, are suited for applying LIDC type electrical stimulation current to the wound area and for bioimpedance measurement.

  • Patent number: 9649070
    Abstract: Various embodiments relate to a method, apparatus, system, and a computer program product for suppressing an oscillatory signal Sosc. In the method a composite signal S comprising said Sosc and a modulating signal Smod are provided and the S is high pass filtered to produce estimates of the Sosc and the Smod, wherein the estimate of the Sosc comprises first oscillations during a first state of the modulating signal and second oscillations during a second state of the modulating signal. A first bin associated with said first state and a second bin associated with said second state are defined and assigned for said first oscillation and the second bin for said second oscillation according to a state defined from the estimate of the Smod. A first average waveform for said first oscillations and a second average waveform for said second oscillations are formed and used to suppress the Sosc signal from the composite signal S.
