Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bioelectrode pad.

[0002]

2. Description of the Related Art As a bioelectrode pad to be interposed between an electrode and a body when an electric signal from the body is transmitted to a measuring device or an electric stimulation from a stimulator is transmitted to the body, 9 to 11 are available. FIG. 9 shows an electrocardiographic electrode pad. This electrode pad is
A conductive metal film 61 is attached to the insulating resin film 60, and the adhesive conductive gel 6 is attached to the conductive metal film 61.
2 is attached, and an alligator clip is attached to the protruding pieces of the films 60 and 61 for use.

FIG. 10 shows a low frequency electrode pad. In this electrode pad, a conductive carbon 71, an adhesive conductive gel 72, a reinforcing member 73, and an adhesive conductive gel 74 are sequentially attached to an insulating resin film 70, and a conductive metal snap male 75 is attached to a corrosion-resistant resin film. It is provided in a protruding shape through 76, and a snap female is attached to the snap male 75 for use.

FIG. 11 shows a low frequency adhesive pad. This pressure-sensitive adhesive pad has a structure in which an adhesive conductive gel 80 is attached to a reinforcing member 8
1 and the adhesive conductive gel 82 are attached in this order, and this is used by attaching it to an electrode formed by attaching conductive rubber to insulating rubber.

[0005]

However, in the conventional bioelectrode pad as described above, in the case of medical use, it is a hygienic problem that the one used for one person is used for another person. It cannot be used, and it is thrown away after being used only once. In the case of household use, it is repeatedly used by one person or shared by the family, but as the number of times of repetition increases, not only is the adhesiveness and feeling of use deteriorated, but it is also a hygienic problem. There is a problem.

[0006] Therefore, the present invention has been made in view of the above problems, it can be used hygienically for both medical and home use without deteriorating the adhesiveness and the feeling of use. An object of the present invention is to provide a new bioelectrode pad.

[0007]

In order to achieve the above object, the bioelectrode pad of the present invention is characterized by having an adhesive layer composed of a plurality of thin films releasably laminated.

[0008]

In this bioelectrode pad, since the adhesive layer is composed of a plurality of peelable thin films, one adhesive layer is used for each use.
By peeling each layer and using it, it can be used hygienically without deteriorating the adhesiveness and the feeling of use.

[0009]

EXAMPLES Hereinafter, the bioelectrode pad of the present invention will be described based on examples. FIG. 1 shows a pad according to the first embodiment. This pad 10 is an adhesive layer (adhesive gel) 1 in which conductive carbon 12 is adhered to an insulating resin film 11 and a plurality of thin films are releasably laminated on the conductive carbon 12.
3 is attached. The thin films forming the adhesive layer 13 have the same thickness. Also, the number of laminated thin films is
Although it depends on the thickness of each thin film, the use and size of the pad, the feeling of use, etc., about 10 to 20 is suitable. Inside the pad 10, as described above, the conductive metal snap male 14 is provided in a protruding shape via the corrosion resistant resin film (not shown). As shown in FIG. 2, this pad 10 has a snap female 40 attached to a snap male 14, and
Each time it is used, the adhesive layer 13 is peeled off by one layer 13 _-1 and used.

The pad 20 of the second embodiment shown in FIG.
The adhesive layer 21 is made up of thin film layers, and the thickness of each thin film of the adhesive layer 21 is the same. As shown in FIG. 4, the pad 20 is made of an insulating resin film 50.
The conductive carbon 51 is adhered to the conductive carbon 51 side of the electrode 52, and the adhesive layer 21 is peeled off one layer 21 _-1 each time it is used once.

The pad 30 of the third embodiment shown in FIG.
An adhesive layer 31 made of laminated thin films of the same thickness,
It is attached to a thick reinforcing gel 30 made of the same material. Similar to the pad 20, the pad 30 is also used by adhering it to the electrode 52 in which the conductive carbon 51 is adhered to the insulating resin film 50 and peeling the adhesive layers 31 one by one 31 _-1 .

The pad 20 of the fourth embodiment shown in FIG.
In a modified example of the pad 20 of FIG. 3, a plurality of thin films forming the adhesive layer 21 are provided with sticking or non-sticking protrusions 22 for peeling, respectively. In this case, when the adhesive layer 21 is peeled off one layer 21 ₋₁ in FIG.
2 _-1 can be used as a starting point, adhesive layer 2
It becomes easy to peel off 1 layer by layer. However, the protrusion 22
May be tacky, but non-tacky improves operability.

[0013]

The bioelectrode pad of the present invention has the following effects because it has an adhesive layer formed by peelably laminating a plurality of thin films as described above. (1) It is not necessary to dispose of each time it is used, and it can be kept hygienic and clean even if it is repeatedly used for personal use or shared with other people. (2) Even after repeated use, it is possible to easily maintain the initial performance, adhesiveness, feeling of use, measurement and irritation performance. (3) Since it has a thin film laminated structure, it does not require a gel reinforcing material and can maintain flexibility. (4) By providing the plurality of thin films forming the adhesive layer with adhesive or non-adhesive protrusions for peeling, it becomes easy to peel the thin films one by one.
