Abstract

Electrode with high electrical contact and mechanical fixation quality, characterized in that the functions of electrical contact and mechanical fixation on the skin are materially and spatially separate.

Description

In human and veterinary medicine, as well as in cosmetics and body care, flexible electrodes are applied to the skin of humans or animals in order to introduce electrical currents into the respective living beings or to derive them from them. The coating of the electrodes used hitherto, which is directed towards the skin of the living being, is conductive for the electric current to or from the skin and at the same time has to mechanically fix the electrode on the skin. These electrodes are used for short-term applications (e.g. ECG, EMG, electro-impedance measurements and electro-therapy) and for long-term applications (e.g. long-term ECG, long-term blood pressure measurements, electro-therapy after torn muscle fibers and sports injuries, high-frequency therapy and body care using electrical signals according to Dr. Rife). In long-term applications, the application of the electrodes takes several hours to several days due to further developed medical and cosmetic methods. The current development of methods is characterized by an increasing tendency of application duration.

The progressive miniaturization of the devices used has already led to applications on the body of humans or animals to be used on an outpatient basis, with the living beings concerned moving freely during the application and thereby being able to pursue their daily activities without restriction. The conventional adhesive electrodes, also known as adhesive electrodes, are increasingly unable to meet the resulting increased quality requirements for the conductive electrical contact and the simultaneous secure mechanical fixation on the skin.

Duration and frequency of application as well as the reliable application in sweaty movement of living beings (e.g. in athletes and other living beings during physical movement) overtax the functional properties of conventional adhesive electrodes and endanger the success of medical and cosmetic procedures.

A short-term replacement of the electrodes within the application times is not practicable, jeopardizes the desired success of the respective method and is uneconomical due to the increased material and time expenditure.

As a remedy, a common substance for the coating is still not to be used, which is intended to ensure both electrical contact with the skin and mechanical fixation on the skin. According to the invention, these two functions, electrical contact to the skin on the one hand and mechanical fixation of the electrode on the skin on the other hand, must be materially and spatially separated.

The problem can be solved by means of the invention presented here. The realization on which the invention is based consists in separating electrical contact and fixing in terms of material and space.

This problem is solved with the features listed in claim 1 for protection. The invention achieves that the two functions, electrical contact and mechanical fixation, are separated in the electrode in such a way that the surface areas for the electrically conductive foil (2) are separated from those of the fastening tape (1) for mechanical fixation of the skin.

According to the features listed in claim 2 and claim 3, the surface area for mechanically fixing the fastening strap (1) also fixes the electrically conductive film (2) on the fastening strap (1).

According to the features listed in claim 4, the electrode on which the invention is based can optionally be equipped with metallic or non-metallic electrically conductive foils (2). This selection is independent of the adhesive used on the fastening tape.

According to protection claim 5, the electrical contact (3) functions as a further connection, which is optionally designed as a plug-in or clamp connection.

An embodiment of the invention is explained with reference to the drawing. It shows schematically an electrode viewed from the surface facing the skin.
