An electrode carrier system includes one or more electrode assemblies having an electrode body. One or more tubular members extend from the electrode body and define a lumen terminating in a distal opening. The electrode assemblies carry a reservoir containing a conductive fluid or gel. The reservoir is in fluid communication with the lumens in the tubular members, and the electrode assemblies are typically supported on a backing which may optionally be configured as a headband. Systems are for tracking patient movement may be used in combination with the electrode carrier system.

Methods and systems incorporating non-linear dynamic (NLD) analysis such as entropy or other complexity analysis monitoring continuous or evoked signals from a biological subject are presented, where such a system comprises of processing steps including: a) the combination of a biological signal evoked as a result of patient stimulation presented to a biological subject and a non-linear analysis method capable of capturing temporal changes in signal order or regularity; b) any combination of processed evoked or continuous central nervous or peripheral physiological mechanisms b) a means to generate a measure indicative of a patient's level of anaesthesia and consciousness depth (A&CD), sedation or sleep/wake state. Methods and systems incorporating a NLD analysis means to improve the discrimination between different signals origins including any combination of: a) central nervous system (CNS), b) peripheral control or nervous system (PNS), c) autonomic control or nervous system (ANS), d) arousals, and e) artifacts.

The group of inventions relates to medicine (physiotherapy). Electric stimuli which are generated by the following ringing circuit: active electrodeinductive storage unitpassive electrodeinterelectrode tissuesactive electrode, contain oscillations which are used as a test signal. In one variant of the method the electrodes are successively applied (in another variantmoved uniformly) across the skin area. Every time the electrodes-to-skin contact is detected, the oscillation parameters are recorded after a delay. Moreover, the values of parameters can be averaged. The group of invention provides the use of both combined and disjointed (separated) electrodes. An optimal zone for electropulse therapy is identified by minimal or maximal value of one or more parameters of the aforementioned oscillations and the use of the principle of small asymmetry. The group of inventions provides an increase in the accuracy with which zones optimal for electropulse therapy are identified and localized.

The present disclosure provides systems, apparatuses, and methods for use of wearable electrode assemblies. The electrode assemblies improve comfort by providing increased overall surface area of their bottom surfaces, which make contact with the patient's scalp and hair. Collapse, compression, or telescoping of the bottom surface will thereby decrease the direct force and/or pressure applied by the distal member or members of the bottom surfaces to the skin. This may be advantageous in patients who have little to no hair in electrode contact areas, patient populations that are particularly skin-sensitive, and/or patients which must wear the electrode assemblies of an extended time period. The electrode assemblies further include structures to dispense and/or maintain conductive gel placed over the patient's skin, thereby maintaining electrical connection quality, and/or to facilitate the clearing of skin and/or hair prior to establishing an electrical connection.

What is disclosed is a measuring device for measuring biosignals of a creature comprising a measurement electrode, a stimulation electrode and a control unit. The control unit stimulates by means of the stimulation electrode nerve fibers of the body of the creature at a positioning location of the measurement electrode, such that sweat is produced at the positioning location. The invention also refers to a corresponding method.
