A device for measuring electrophysiological data includes: a series of electrodes; a control circuit including a DC voltage source connected to the electrodes in order to apply, to a pair of electrodes, DC voltage pulses, and in order to connect another high-impedance electrode; and a measurement circuit for measuring the potential of the electrodes and data representative of the current passing through at least one active electrode. The device further includes at least one base incorporating the control circuit and the measurement circuit, and a housing suitable for receiving an electrode assembly which includes at least one electrode of the series in a removable manner, so as to be able to connect or disconnect the electrodes to/from the control circuit and to/from the measurement circuit.

Device for measuring electrophysiological data with improved reliability

Electrode

The invention relates to an electrophysiological analysis system which comprises a plurality of electrodes (E-E), power supply means () for successively applying a substantially continuous voltage ranging approximately from 1 to 5 volts and lasting from 0.1 to 5 seconds to different slotted electrode pairs, collecting and storing means () for recording the variation of a current flow in the electrode pairs to which said voltage slots are applied, means () for enabling the current variations obtained by comparison between at least two current variations caused by supposed identical conditions and means () for comparing data related to the current variations recorded for several electrode pairs and enabled with reference data. Said invention can be used for chronoamperometrically detecting pathologies, pathological areas and organ dysfunctions.

Electrophysiological analysis system and method

The invention provides an electrophysiological analysis system, in particular for detecting pathological states. This system comprises: electrodes intended to be placed in different regions of the body that are well away from each other; an adjustable DC voltage source for generating successive DC voltage pulses varying in magnitude from one pulse to another, the duration of the pulses being equal to or greater than about 0.2 seconds; a switching circuit for selectively connecting a pair of active electrodes to the voltage source and for connecting at least one other high-impedance electrode; and a measurement circuit for recording data representative of the current in the active electrodes and potentials on at least certain high-impedance connected electrodes in response to the application of said pulses. The range of voltages covered causes, from one pulse to another, the appearance or disappearance of electrochemical phenomena in the vicinity of the active electrodes.
