  • Patent number: 8909334
    Abstract: An electrical stimulation device and method of locating an electrical stimulation point of a human or animal. The device comprises a matrix of electrodes distributed on an electrode pad configured to be applied on a human or animal body and arranged for covering a plurality of the stimulation points of the human or animal. An electronic circuit is connected to the matrix of electrodes and configured for applying an electrical stimulation signal to the electrodes. A feedback signal, in response to an electrical stimulation signal, may be used in assessing the suitability of electrodes as an electrical stimulation point.

  • Patent number: 8620434
    Abstract: A device and method for applying transcutaneous electrical nerve stimulation via an electrode. The device includes the electrode being arranged for detecting a change of a skin impedance and being configured for switching from a stimulation mode of operation for stimulating the nerve, into a recalibration mode of operation upon detection of the changed skin impedance. The device may include a plurality of electrodes being configured for detecting the change of the skin impedance and being configured for adjusting an electrical current flowing through the skin via the plurality of electrodes.

  • Publication number: 20110264002
    Abstract: The invention relates to an electrical stimulation device (10) and to a method of locating an electrical stimulation point (132s, 138s) of a human or animal. The electrical stimulation device comprises:—a matrix of electrodes (120 . . . 140) distributed on an electrode pad (20) being configured to be applied on the human or animal body, the distribution of the electrodes in the matrix being arranged for covering a plurality of the stimulation points of the human or animal,—an electronic circuit (30) being connected to the electrodes of the matrix, and being configured for applying an electrical stimulation signal (TS, PSS, FES) to the electrodes of the matrix, and—feedback means (20, 40, 42) for providing a feedback signal (FS1, FS2, FS3) to the electrical stimulation device in response to the applied electrical stimulation signal.

  • Publication number: 20110071419
    Abstract: The present invention provides a location indicating device (10) for determining on skin of a human or animal body a location for performing measurement of a physiological parameter in and/or treatment of the human or animal body. The location indicating device (10) comprises a matrix (7) of electrodes for determining skin resistance at different locations on skin of a human or animal body and a calculating unit (8) for calculating a location with highest skin resistance. The location indicating device (10) furthermore comprises visualisation means (9) for indicating the location of highest skin resistance to a user. The present invention also provides a method for making such a location indicating device (10) and a method for determining on skin of a human or animal body a location for performing measurement of a physiological parameter in and/or treatment of the human or animal body by using such a location indicating device (10).

  • Publication number: 20110066209
    Abstract: The invention relates to a device (10) for applying transcutaneous electrical nerve stimulation via an electrode (22), and to a method of transcutaneous electrical nerve stimulation. The device comprises the electrode being arranged for detecting a change of a skin impedance and being configured for switching from a stimulation mode of operation (30) for stimulating the nerve into a recalibration mode of operation (32) upon detection of the changed skin impedance. In an embodiment, the device comprises a plurality of electrodes being configured for detecting the change of the skin impedance and being configured for adjusting an electrical current flowing through the skin via the plurality of electrodes.

  • Publication number: 20100087903
    Abstract: The invention provides an electro-therapeutic device for application on a human or animal body part, comprising electrodes (3), a measuring means connected thereto and arranged to measure a value of an electrical quantity, and a control unit (10) to process the measured values, wherein the control unit (10) further comprises pattern recognition means to determine a pattern in the measured values, for example by comparing with patterns stored in a memory unit (15). By means of the determined pattern, the device is able to know its position on the body, and to determine whether this position is suitable for a treatment, and to which electrodes a treatment signal must be supplied. The device is much easier to use since it does not require any user's knowledge about patterns, as this may be stored in the device itself.
