- the invention relates to a medical electrode for deriving signals from the human skin with at least one contact point for taking the signal from the skin of a patient and a laterally offset with respect to the contact point means for relaying the signal to a signal acquisition or signal processing unit, wherein the at least one contact point for removing the signal from the skin is connected to the means for relaying the signal by means of a signal conductor.
- Such electrodes have been known for a long time, wherein the contact between the skin of the patient and the signal conductor is usually produced at the contact point by means of an electrically conductive gel.
- the means for delivering the signal can be prevented that when connecting an electrode cable to the agent due to the applied pressure gel to the adhesive surface of the electrode passes, as in the case of electrodes in which the means for dispensing or Forward the signal centrally, d. H. at the contact point of the signal conductor with the skin of the patient, arranged, was frequently the case.
- the object of the invention is to provide an improved, universally applicable medical electrode.
- At least one contact point is assigned at least one further laterally offset means for outputting or forwarding the signal to a signal acquisition or signal processing unit.
- At least two of the means for outputting or forwarding the signal to a signal acquisition or signal processing unit are advantageously designed differently.
- the medical electrode according to the invention can be used independently of the type of connections of the signal acquisition or signal processing unit. This is important because different organizations such as Rescue, Red Cross, or Clinics use different signal acquisition units with different terminals. So far, it has therefore been necessary to produce several series of the various medical electrodes, each of which was provided with a connection corresponding to a signal acquisition or signal processing unit.
- the inventive equipment a medical electrode with two laterally offset, various means for dispensing or forwarding of Signal this disadvantage is avoided and created a cost-effective, universally applicable medical electrode.
- a first exemplary embodiment of the invention provides that the at least two means assigned to a contact point are connected to the contact point via a common signal conductor, while according to an alternative embodiment of the invention the at least two means assigned to a contact point are connected to the contact point via separate signal conductors are, wherein the separate signal conductors are electrically connected to each other, preferably at one contact point.
- the laterally offset means for delivering or forwarding the signal are connected to the one contact point for removing the signal from the skin. Rather essential to the invention is the fact that one contact point is assigned two laterally offset means for outputting or forwarding the signal.
- the medical electrode has a carrier element and at least one tapping tab projecting beyond the outer edge of the carrier element, wherein at least one means for delivering or forwarding the signal to a signal acquisition or signal processing unit at this Abgrifflasche is arranged.
- the medical electrode according to the invention comprises two decentralized means for delivering the signal, at least one of which means is arranged on a preferably flexible tab, whereby a stable, interference-free signal is ensured. If the signal is relayed by means of an electrode cable, the inventive configuration of the medical electrodes ensures that even movements on this electrode cable do not impair an accurate and reliable recording of the signal.
- a further embodiment of the invention provides that the medical electrode has at least one tapping tab on which at least two means for delivering the signal to a signal acquisition or signal processing unit are arranged. It is also possible for the medical electrode to have a plurality of tapping tabs, wherein at least one means for delivering or forwarding the signal to a signal acquisition or signal processing unit is provided on each tapping tab it has been found to be particularly favorable when the medical electrode has a plurality of tapping tabs, wherein at each tapping tab exactly one means for delivering or forwarding the signal to a signal acquisition or signal processing unit is arranged.
- a further embodiment of the invention provides an additional means, arranged at the contact point for removing the signal from the skin, for outputting the signal to a signal acquisition or signal processing unit, whereby the number of preferably different means for delivering the signal Signal can be increased.
- the means for delivering the signal to a signal acquisition or signal processing unit comprise according to a preferred embodiment of the invention, a push button and / or a plug, preferably a banana plug, and / or are for connecting a terminal, preferably an alligator clip, and / or designed for contactless transmission of the signal.
- the novel medical electrode on a flexible insulating support member having a passage opening for receiving an electrically conductive gel, wherein on one side of the support element, preferably over the entire surface, an adhesive layer for attaching the electrode on the skin of the patient and on the the adhesive opposite side of the support element, a signal conductor, preferably in the form of a signal conductive layer, is arranged, which can be brought into contact with the skin of the patient at the contact point via the electrically conductive gel.
- a cover layer Arranged above the signal conductor and the carrier element is a cover layer, preferably in the form of a label, which has a tapping tab projecting beyond the outer edge of the carrier element, at which two differently configured means for delivering or forwarding the signal to a signal acquisition or signal processing unit are arranged.
- FIG. 1 shows schematically a cross section through a first embodiment of a medical electrode according to the invention
- Fig. 2 shows schematically an exploded view of a medical electrode according to the invention
- the medical electrode 1 shown in FIGS. 1 and 2 comprises - from bottom to top - an adhesive layer 10 made of a skin-compatible adhesive, a flexible insulating carrier element 7 made of a polymeric foam, a metallic signal conductor 5, for example made of carbon, and a label-shaped cover layer 8 on.
- the signal conductor 5 and a signal conductor 5 overlapping portion of the cover layer 8 project laterally relative to the carrier element 7 and form in this way a tapping 9th

- a means 3 is designed as a push button or plug and the other means 3 'for connecting a crocodile clip 11 connected to an electrode cable 14.
- a cover 12 is arranged, on the one hand protect the signal conductor 5 from interference and on the other hand should prevent the contact of the signal conductor 5 with the skin of the patient.
- the signal is taken from the skin of the patient at the contact point 2, via a arranged in a passage opening of the flexible support member 7 electrically conductive gel 6, which is in communication with the signal conductor 5.
- the signal conductor 5 may be provided in the region of the electrically conductive gel 6 on its side facing the gel with an Ag / AgCl coating.
- the signal conductor 5 is formed as a purely metallic conductor, it goes without saying that the signal conductor 5 could also be printed, for example on the underside of the cover layer 8. It would also be conceivable Signal conductor 5 on its side facing away from the carrier element 7 to isolate by forming the signal conductor 5, for example, as a two-ply film, wherein one side of the film is electrically conductive, while the other side is electrically insulating. In this case, the tapping tab 9 could be formed directly from the protruding part of the signal conductor 5 formed as a two-ply film, so that the cover layer 8 would only have to have the size of the carrier element 7.
- the two differently shaped means 3, 3 ' are arranged to dispense or forward the signal decentrally on the electrode 1, results in an improved, d. H. more stable, ECG signal.
- the inventive medical electrode 1 by the decentralized arrangement of the means 3, 3' also more tolerant of movements on the electrode cables 14.
