Description

Beschreibung Zur Ableitung der bio-elektrischen Aktionspotentiale von der Körperoberfläche des Versuchsobjektes bei der Elektrokardiographie werden zumeist plattenförmige Elektroden verwendet. Description For deriving the bio-electrical action potentials from the body surface of the test object during electrocardiography mostly plate-shaped electrodes are used.

Die Elektroden sind aus Metall oder Metall-Tuch hergestellt.The electrodes are made of metal or metal cloth.

Als Metall wird Feinsilber oder nichtrostender Stahl bevorzugt angewandt, weil diese Metalle mit der Haut des Versuchsobjektes die geringsten Polarisationsspannungen erzeugen.Fine silver or stainless steel is preferred as the metal, because these metals have the lowest polarization voltages with the skin of the test object produce.

Zur Vermeidung hoher Ubergangswiderstände wird zwischen Haut und Metall ein mit schwach allk<liischer Lösung getränktes Tuch oder Papier-Tuch gelegt. To avoid high contact resistance, a cloth or paper towel soaked with a weak general solution is placed between the skin and the metal.

Die Elektroden werden mit elastischen Bändern oder Saug-Glocken gegen die Haut gedrückt. Die Fortleibung der bioelektrischen Aktionspotentiale erfolgt durch isolierte Litzendrähte.The electrodes are opposed with elastic bands or suction bells pressed the skin. The bioelectric action potentials are carried forward through insulated stranded wires.

Es bestand die Aufgabeß die Polarisationsspannungen und den Übergangswiderstand so niedrig wie möglich zu halten. Gleichzeitig sollten sich vorgenannte Werte nicht oder nur geringfügig ändern, wenn sich das Versuchsobjekt bewegt und durch die Kontraktion der Muskulatur der Andruck der Elektroden geändert wird.The task consisted of the polarization voltages and the contact resistance as low as possible. At the same time, the aforementioned values should not or change only slightly as the subject moves and due to the contraction the muscles the pressure of the electrodes is changed.

Weiter war gefordert, dat auch nach tagelangem Aufliegen der Eleko trode die eingangs erhobenen Forderungen erfüllt wurden.Another requirement was that even after the Eleko had been lying down for days trode the requirements raised at the beginning have been met.

Dieses läßt sich mit den bekannten, eingangs beschriebenen Elektrodenausführungen nicht befriedigend erreichen.This can be done with the known electrode designs described at the beginning not achieve satisfactorily.

Die Erfindung bezieht sich auf eine Elektrodenausführung, die diese Forderungen erfüllt.The invention relates to an electrode design that this Requirements met.

Abb. i zeigt die Darstellung der Elektrode in der Draufsicht Abb. 2 zeigt den Schnitt AB durch die Elektrode in ca. 3-fach vergrößterter Darstellung Die Elektrode (i) ist aus Gummi hergestellt, dem eine Mischung aus Aktiv-Kohlen-Pulver und Graphit kalt beigemengt wurde. Die Aktiv-Kohle hat die aufgabe, die sauren und / oder alkalischen Trans pirationsprodukte der Haut zu binden. Um die aktive Fläche der elastischen Elektrode (i) zu vergrößern, werden die an der Haut anliegenden Flächen der Elektrode aufgerauht. Eine mittlere von ca. 50 µ erwies sich als optimal. Graphit und Aktiv-Kohle dienen der Leitbarmachung des Gummis.Fig. I shows the representation of the electrode in a top view. Fig. 2 shows the section AB through the electrode in approx. 3 times enlarged representation The electrode (i) is made of rubber, which is a mixture of activated carbon powder and graphite was added cold. The task of activated charcoal is to bind the acidic and / or alkaline transpiration products of the skin. In order to increase the active area of the elastic electrode (i), the areas of the electrode which are in contact with the skin are roughened. A middle one of approx. 50 µ turned out to be optimal. Graphite and activated carbon are used to make the rubber conductive.

Abb. 2 zeigt, daß die Elektrode aus zwei aufeinanderliegenden Gummiplatten (4a) und (4b) besteht. Die innenliegenden Flächen der Gummiplatten (4a/4b) sind mit Leitsilberlack (5) bestrichen. Dieses dient der Fortleitung der bioelektrischen Aktionsspannung an die bei (2) einvulkanisierte Leitung (3), über die die Verbindung z.B. zum Elektrokardiographen hergestellt wird.Fig. 2 shows that the electrode consists of two rubber plates lying on top of one another (4a) and (4b) exist. The inner surfaces of the rubber plates (4a / 4b) are coated with conductive silver paint (5). This serves to transmit the bioelectrical Action voltage to the line (3) vulcanized in at (2) through which the connection e.g. for the electrocardiograph.

Die abgebildete Formgebung ist nicht zwingend. Die Elektrode kann stabförmig, kreisförmig oder auch' oval sein. Ebenso ist die Anwendung auf die Anwendung bei der Elektrokardiographie nicht beschränkt, sie ist vielmehr auch zur Elektromyographie und zur Elektro-Encephalographie verwendbar.The shape shown is not mandatory. The electrode can be rod-shaped, circular or also 'oval. The same applies to the application Not limited to electrocardiography, rather it is also used to electromyography and usable for electro-encephalography.
