【発明の詳細な説明】
本発明は、心電図計や脳波計等の生体電位測定
装置や低周波治療装置に接続して使用される生体
電極の界面基材構造及びその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interface base material structure of a bioelectrode used in connection with a biopotential measurement device such as an electrocardiogram or an electroencephalogram or a low frequency treatment device, and a method for manufacturing the same.
一般にこの種の生体電極例えば生体電位測定用
電極としては、吸盤状弾性体に金属電極を内設し
て、前記弾性体の吸引力により皮膚に金属電極を
接触させるようにしたものや、金属板等の導電性
部材をバンド等により皮膚に圧着するようにした
電極が使用されていた。 In general, this type of bioelectrode, for example, an electrode for measuring biopotential, is one in which a metal electrode is installed inside a suction cup-shaped elastic body and the metal electrode is brought into contact with the skin by the suction force of the elastic body, or a metal plate. An electrode was used in which a conductive member such as the above was crimped onto the skin using a band or the like.
しかし、前者の電極では金属電極と皮膚との導

意の場所に固定するのは非常に難かしく、場所に
よつては固定できない場合もあつた。さらに被測
定者のわずかな動きで容易にずれてしまい正確な
測定をすることができない欠点も有していた。 However, with the former electrode, a cream containing an electrolyte must be interposed to improve conductivity between the metal electrode and the skin, and wiping off this cream after use is extremely troublesome. Furthermore, since this electrode uses a method of fixing the skin by suction, it has the disadvantage that the skin becomes bloodshot and painful when used for a long period of time.
In addition, with the latter electrode, it is very difficult to fix it to any arbitrary location on the skin of a three-dimensional human body, and it is sometimes impossible to fix it depending on the location. Furthermore, it has the disadvantage that it is easily displaced by the slightest movement of the person to be measured, making it impossible to perform accurate measurements.

968489) was invented. That is, these electrodes A, for example, as shown in FIG.
The interface base material 4 itself has conductivity, shape retention, and adhesiveness, and it adheres to the skin extremely well by simply pressing it onto the living body without using any cream or fixing band. It is fixed.
しかしながら、この電極の界面基材４はいずれ

用電極としての性能に著しく悪影響を与えるもの
であつた。さらに界面基材が周囲にはみ出した状
態は美観をそこねるばかりで無く、剥離時の操作
性にも著しく悪影響を与えるものであつた。 However, in all cases, the interface base material 4 of these electrodes was manufactured by punching out a sheet that was previously formed into a sheet shape, so the peripheral surface 5 of the electrode was exposed. It was hot. Therefore, when used in a humid place, when a large amount of sweat occurs, when used for a long period of time, or when extreme external pressure is applied, the interface base material 4 deforms and escapes toward the periphery of the electrode. This had a significant negative effect on the performance of the electrode. Furthermore, the state in which the interfacial base material protrudes into the surrounding area not only impairs the aesthetic appearance, but also has a significant adverse effect on the operability during peeling.
また、シート状に成形した界面基材を打抜いて
製造する方法はその工程上歩留まりが極めて悪く
無駄な材料が多量に放棄されているものであつ
た。 In addition, the method of manufacturing by punching out an interface base material formed into a sheet has an extremely poor yield due to the process, and a large amount of wasted material is wasted.

The purpose is to provide a manufacturing method that can be obtained.

とを有する生体電極用界面基材１１が得られる。 Next, one embodiment of the method for manufacturing the above interface base material will be described in detail with reference to FIGS. 4 and 5. First, the mold cylinder body 24 is formed from the peripheral frame sheet 21, the smooth paper 22, and the hard pipe 23. The hard pipe 23 is made of vinyl chloride, for example, and has a smooth paper 22 that has been subjected to a smooth surface treatment, such as a silicone treatment, in close contact with its inner peripheral surface. Further, on the inner circumferential surface of the smooth paper 22, a flexible open-celled material such as polyurethane foamed in a cylindrical shape or a peripheral frame sheet formed into a cylindrical shape by bonding the two opposite sides of a foamed polyurethane sheet. 21 are arranged in close contact with each other. A mixer 2 is attached to this mold cylinder body 24.
The pad composition 26 mixed in step 5 is poured and filled. The pad composition 26 is, for example, a liquid mixture of 45 parts by weight of karaya gum, 50 parts by weight of glycerin, and 5 parts by weight of sodium chloride. 27 is a part material. This pad part material 27 is obtained by hardening the pad part composition 26 by appropriate means, such as allowing it to stand naturally for about 1 to 2 hours, or heating it at about 80 DEG C. for about 5 minutes. 28 is a base columnar body. This base material columnar body 28 is composed of the hardened pad material 27 and this pad material 27.
and a peripheral frame sheet 21 adhesively fixed to the outer peripheral surface of the pipe, and is removed from the rigid pipe 23. This base columnar body 28 is cut into a disc-shaped rotary blade 2.
By slicing the pad to a desired thickness at step 9, a pad portion 12 and a peripheral frame 13 having the same thickness as the pad portion 12 and integrally provided at its periphery are obtained.
An interface base material 11 for a bioelectrode having the following is obtained.

In addition, materials for the interface base material may be selected from those disclosed in JP-A No. 81635 of 1981, JP-A No. 95895 of 1972, or JP-A No. 77489 of 1974, depending on the use of the present invention. Any material may be used as long as it has electrical conductivity, shape retention, and adhesiveness, and is cured by an appropriate means in an initially fluid state. Furthermore, although the peripheral frame has been described using foamed polyurethane, other foams such as polyethylene may be used, or vinyl chloride, rubber, or the like may be used.

Alternatively, the inner peripheral surface of a hard pipe may be smoothed. Furthermore, the outer circumferential surface of the peripheral frame sheet may be smoothed to facilitate removal. In addition, instead of a hard pipe, a soft vinyl or the like is used as the mold cylinder, and the pad composition is filled into this, and the hardened base column is placed inside, and the mold cylinder is sliced and cut. It's okay if it's hot. Furthermore, the base material columnar body is further hardened,
In order to reduce deformation during cutting and reduce adhesion to the blade, it may be cooled and solidified at -30°C to -40°C for about 3 hours after being filled into the mold cylinder. Further, in order to facilitate slicing, the base columnar body may also be rotated in the opposite direction to the rotation of the blade. Further, the cutting means may be appropriately selected depending on the purpose and material, such as cutting with a jig saw or cutting with laser light.

果を有する。 As is clear from the above explanation, according to the interface base material for a bioelectrode of the present invention, since the peripheral frame having the same thickness as the pad part is integrally provided on the peripheral edge of the pad part, It has extremely good shape retention even when used under harsh conditions. In addition, since the shape retention property is good, there is little deformation even when reusing it, and furthermore, even when it is removed by peeling from the backing member, it can be removed extremely easily since there is a non-adhesive part on the periphery. Also in this case, since the peripheral frame is provided, deformation is less likely to occur.

る。 In addition, according to the method for manufacturing an interface base material for a bioelectrode of the present invention, since the base material columnar body is sliced and cut, the yield of the material can be significantly improved compared to the conventional sheet punching method. The manufacturing space can also be reduced. Furthermore, since the peripheral frame sheet covers the peripheral side of the base columnar body, there is less deformation during processing and cutting.
Furthermore, since the peripheral surface is non-adhesive, its operability is also extremely good. Furthermore, according to the present manufacturing method, it is possible to manufacture an electrode-integrated interface base material for an iontophoretic plaster structure extremely easily and accurately, which was not possible using the sheet punching method.
