Problems solved by technology

Needle electrodes, of course, have the disadvantage that the penetration can be assessed as an invasive operation into the human body with corresponding associated risks, for which specific medical knowledge is required
[0010] However, the disadvantage of this strip is that the surface electrodes are arranged successively on the strip
Therefore, deviations from this line are only possible to a limited extent, so that positioning is partly difficult and expensive

Embodiment Construction

[0051] For recording SEMG, surface electrodes are used for measuring SEMG signals on the patient's skin. Here, for example, silver-silver chloride gel electrodes known from the prior art are used. Such surface electrodes are readily and widely available, since they are also used, for example, for EKG recordings.

[0052] figure 1 An example of a surface electrode 101 , also referred to below as electrode 101 for short, is schematically shown. The electrode 101 has a carrier layer 102 on the underside of which an adhesive surface 103 is applied. With this adhesive surface 103 the electrode 101 can be glued to the patient's skin so that the electrode 101 cannot slip during signal recording.

[0053] The carrier layer 102 consists, for example, of a nonwoven, a sponge or a film. There are different embodiment possibilities for the adhesive surface 103 . When it is feasible or preferable to only cover the skin surface in a small amount by the adhesive surface 103, for example...

Abstract

The invention relates to a sensor device for the electromyographic recording of muscle signals on the skin of a living body, comprising at least two recording electrodes and an earth electrode. The electrodes comprise a common carrier layer that has at least one perforation at which the carrier layer can be separated. After the separation of the carrier layer at the perforation, each electrode is located separately on a separated part of the carrier layer. Further, the sensor device comprises at least one shielded cable, one end of which is connected to one of the electrodes and the other end of which is connected to a contact element. The contact element can be connected to an evaluation unit by means of a connecting element such that signals can be transmitted to the evaluation unit.

Description

technical field [0001] The present invention relates to a sensor device for electromyographic recording of muscle signals on the skin of a living body, the sensor device comprising at least two recording electrodes and a ground electrode. The invention also relates to a method and a system for applying such a sensor device. Background technique [0002] In modern medicine, electromyography is used in particular for the electrodiagnosis of muscle diseases and disorders. In this method, a signal which can be detected in a measurement manner is recorded, which is an electrical potential fluctuation in the muscle which reflects muscle activity. During electromyography, electrical activity in resting and contracting muscles is measured and then compared to normal values. For this purpose, a resting muscle is stimulated after a measurement in order to achieve a muscle contraction, the resulting electrical activity of which is likewise detected. The method of electromyography in...
