[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode for a living body which is attached to the skin of a living body and detects an electric signal such as an electrocardiogram of the living body.

[0002]

2. Description of the Related Art Conventionally, as an electrode for a living body for detecting an electric signal such as an electrocardiogram of a living body, an electrode element is fixed by penetrating a foam tape as a flexible support member, and a paste is applied to one surface of the foam tape. There is known a configuration in which an adhesive such as an adhesive is applied, and the adhesive is fixed to the skin surface of a living body with the adhesive.

[0003] those using a bioelectrode composition as described in JP-B-63-59334 are also known. A biological electrode using this composition is configured as shown in FIG. In FIG. 3, a sheet-shaped base material 11 is attached to a backing material 12 formed of paper, a synthetic resin film, a nonwoven fabric, or the like, and an electrode element 13 is connected to the base material 11 through the backing material 12. ing. Substrate 11 is 2
Composition comprising 0% to 60% by weight of 2-acrylamido-2-methylpropanesulfonic acid and / or a salt thereof, 10% to 50% by weight of water, and 0.1% to 5% by weight of a crosslinking agent as essential components. It is composed of things. This composition is in the form of a translucent gel having conductivity, and AMP
Called S.

Among the above-mentioned conventional electrodes for a living body, the one in which the foam tape is adhered and fixed to the skin of a living body via an adhesive is such that when the living body moves, the foam tape rubs the skin and rashes. There was a problem that it was easy. Further, when the electrode is peeled off from the skin, the adhesive may peel off the keratin of the skin. In addition, the adhesive flows out,
There was also a problem that the adhesive strength deteriorated over time.

[0005] On the other hand, the biomedical electrode based on AMPS has a feature that it can be firmly adhered to the skin by the adhesive force of AMPS, does not flow out, and the adhesive force is maintained. Further, there is an advantage that even if the living body moves while the electrodes are being worn, the AMPS does not break down, and a rasp effect does not occur and no rash occurs. Moreover, the skin does not become horny when the electrodes are removed. However, AMPS has a problem in that since it has low strength, it is partially peeled off from the backing material when the electrode is peeled off, and remains on the skin.

The present invention has been made in view of such a point, and provides a living body electrode in which even when AMPS is used, when the electrode is peeled from the skin, a part of the AMPS does not separate and remain on the skin. The purpose is to do.

[0007]

In order to achieve the above object, the present invention removably attaches to the surface of the skin of a living body,
A biological electrode for detecting the electrical signal of the living body through the skin, comprising a label as a holding material, an electrode element fixed through the label, and a mesh-shaped, brim portion.
The label of the electrode element formed in a hat shape
With a gap to the part that appears on one side of
Enclosed, reinforcing material wherein the flange portion is bonded fixed to the label
And a conductive transparent material that impregnates and covers the inside and outside of the reinforcing material.
And a gel .

[0008]

According to the above construction, the conductive transparent gel is impregnated with the reinforcing material and held firmly, and the reinforcing material is adhered and fixed to the label.
The conductive transparent gel does not separate and remain on the skin.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a living body electrode according to the present invention.

FIGS. 1 and 2 show the configuration of an embodiment of the present invention. In the figure, a hat is placed on one side of a disc-shaped label 1.
The flange portion of the mesh reinforcing material 2 shape is bonded and fixed through an adhesive 3. An electrode element 4 penetrates and is fixed to the center of the label 1, and the reinforcing member 2 is integrally impregnated with a disk-shaped AMPS 5. AMPS5
Is molded by pouring into a cylindrical mold having the same inner diameter as the label 1.

According to the living body electrode configured as described above, the AMPS 5 is integrally impregnated with the reinforcing material 2,
Since the reinforcing material 2 is bonded and fixed to the label 1 via the adhesive 3, the AMPS 5 is peeled off integrally with the label 1 when the electrode is peeled off the skin, and does not separate and remain on the skin.

[0012]

As described above, according to the living body electrode of the present invention, the conductive electrode for bonding the electrode to the skin of the living body is provided.
Since the transparent gel is integrally impregnated with the reinforcing material bonded and fixed to the label, it is possible to prevent the conductive transparent gel from separating and remaining on the skin when the electrode is peeled off.
