Abstract

In order to influence the immediate electric environment of a living organism, in particular during electrodiagnosis or electrotherapy, a sheet (23) of electrically-conductive plastic is placed in the vicinity of the body (19). An external electrode arrangement (25) is connected to the mat (23) and the latter is in contact with the body by means of a conductive liquid or paste (21). Use of the mat (23) obviates the need to clean the electrode arrangement (25) after treatment. In addition, the mat (23) is disposable, thereby ensuring optimal hygiene for the treated organism. The mat (23) also affords protection from interfering fields.

description

The present invention relates to an electrode pad for electrical diagnosis or therapy.

It is known, be it for cooling or better contacting or introducing active ingredient, e.g. a conductive liquid or viscous paste is often provided by iontophoresis, in the case of AC or DC therapy, between applied electrodes and the body of the living being. This leads to a covering of the electrode arrangement which is relatively difficult to clean.

The object of the present invention is to solve this problem.

For this purpose, the said electrode support is characterized according to the wording of claim t.

With a support according to the mentioned claim, it is now possible to apply such a liquid or mass only between the plastic film and the body, which eliminates the need to clean the applied electrode arrangement and the plastic film can be thrown away after use, which means only the body of the living being is to be cleaned. Such a support on the body of a person also gives the greatest possible attention to the requirement of medical hygiene and sterility with regard to the electrodes applied and the rest of the environment.

Particularly when using therapy and / or diagnostic devices, high field strengths often arise or exist in the immediate environment of the person mentioned, e.g. 50 Hz interference, which in itself is not or not always used for therapeutic or diagnostic purposes in humans, but has an effect as a disruptive effect. With the above-mentioned requirement, the active connection between the device and the living being can be established via the above-mentioned film, which makes it possible to electrically protect people from these electrical influences, e.g. shield.

Electrically conductive plastic films are known, for example made of polyurethane, polyethylene, PVC with graphite, and are e.g. used to protect highly sensitive electronic components in their packaging.

The invention is subsequently explained, for example, using a figure.

This shows a requirement according to the invention for electrical diagnosis or therapy.

The figure schematically shows a support for electrical diagnosis or therapy according to the invention. A well-conductive, relatively low-viscosity mass 21, for example as a cooling medium, as a reservoir for medications to be introduced iontophoretically during electro-therapy, etc., is applied over a body 19 and covered to the outside by means of a plastic film 23 made of electrically conductive plastic. As indicated schematically at 25, electrodes for electrical diagnosis or therapy are attached outside of this plastic film 23. Depending on the intended use, a therapeutically effective electrical signal is applied to the body 19 via film 23 and mass 21 via these electrodes, or a diagnostically meaningful signal is read from the body 19 via mass 21 and film 23 by means of said electrodes 25. In particular for the use of the film 23 designed as a disposable structure for electro-therapy, a specific electrical resistance in the order of magnitude of 1 k o / cm according to DIN 53 482 is sufficient with regard to the conductivity of the plastic used for the film 23.

After a treatment has ended, the support film 23 is removed and the body 19 is cleaned of the pasty or liquid mass 21. The electrode arrangement 25 does not need to be cleaned because it has not come into contact with the liquid or paste 21. In the case of large-area electrode arrangements 25 and / or arrangements of a large number of electrodes 25, this results in substantial labor savings in the therapy mentioned, optimal hygiene and sterility also being ensured by the disposable pad.
