Description

  The present invention relates to a bioelectrode release sheet for detecting a biosignal provided with a lead wire.

  Conventionally, in a disposable bioelectrode, the adhesive surface provided with the biocontact adhesive of the bioelectrode is provided in a state of being attached to a release sheet. In use, the release sheet is peeled off and the adhesive surface is attached to a living body. The peeled release sheet is usually discarded as it is.

  On the other hand, although it is a disposable bioelectrode, the affixed bioelectrode may be temporarily peeled for reasons such as testing. In such a case, the peeled bioelectrodes are often overlapped, or an adhesive surface is attached to an appropriate place.

  Such a state is a living body electrode in which a release paper is attached to the adhesive surface of the pad of the nonwoven fabric adhesive tape provided with the electrode, and a resin film is applied to the front side surface of the pad in order to enable easy peeling. It is unlikely to be improved even by using a biomedical electrode (see Patent Document 1) thermocompression-bonded so as to extend to the outside of the outer edge of the pad.

In the drawings, the same components are denoted by the same reference numerals, and redundant description is omitted. FIG. 1 and FIG. 2 show a plan view in which a bioelectrode is attached to an embodiment of a bioelectrode release sheet according to the present invention. FIG. 1 shows a state where the bioelectrode release sheet is attached to the lead wire, and FIG. 2 shows a state before the bioelectrode release sheet is attached to the lead wire.

  In these drawings, reference numeral 1 denotes a release sheet as a release sheet for a bioelectrode, and paper or a resin film can be used as a substrate. The electrode mounting surface 11 of the release sheet 1 is subjected to a treatment such as application of a release agent such as silicone to facilitate the release. The electrode 2 is attached to the electrode mounting surface 11. Here, the number of the electrodes 2 is three, but the number is not particularly limited.

  At the right end of FIG. 2, a plan view viewed from the back side of the electrode 2 (side attached to the living body) is shown. As shown, the electrode 2 is a biological electrode for detecting a biological signal, and includes an electrically insulating cover 21 having a substantially circular shape on the surface side. A disc-shaped electrode body 22 is provided at the center of the back side of the cover 21. The electrode body 22 may have various configurations such as a conductor such as Ag / AgCl or a resin obtained by mixing a conductive filler with a resin and solidifying it. The electrode body 22 is embedded with a bio-contact adhesive (conductive adhesive gel) 23, and the surface of the bio-contact adhesive 23 opposite to the cover 21 is an adhesive surface that adheres to the living body.

  A core wire composed of a conductor of the lead wire 3 is connected to the electrode body 22, and the lead wire 3 extends to the outside from a notch 24 formed at the peripheral edge of the cover 21. Further, a tab 25 for easily peeling the electrode 2 from the release sheet 1 is formed at the peripheral edge of the cover 21 opposite to the notch 24.

  The three lead wires 3 are parallel wires, and both end portions are divided one by one. A connector 4 for connecting to a medical device such as an electrocardiograph is provided at the end of the three lead wires 3 opposite to the electrode 2 side.

  The release sheet 1 has an affixing region 12 having an electrode mounting surface 11 for affixing an adhesive surface provided with the biological contact adhesive 23 of the electrode 2.
