脳波を測定するためには、頭部の所定部位に例えば２１個もの数多くの脳波電 極を装着しなければならない。このとき、頭部の皮膚と電極間のインピーダンス や電位差を小さくするために、両者の接触を確実にする必要があり、従来は、例 えば銀板からなる電極の表面に導電用の銀ペーストを塗リ付け、これを１枚ずつ 、粘着剤が塗布されたテープにて脳波測定点の頭部の皮膚に貼り付けていた。従 って、測定を開始するまでに２〜３時間の準備作業を要するとともに、銀板の着 脱時に、被検者に少なからず苦痛を与えていた。そして、銀板を除去した後に頭 部を洗浄して銀ペーストを取り除く必要があった。また、電極の銀板は１cm2 程 度の大きさがあり、ペーストを介して貼り付けても、その間に不純物が介在しや すく、従って、測定が不正確になりやすいが、更には頭部の皮膚が角質化してい ると、頭部の皮膚と電極間のインピーダンスや電位差が大きくなって正確な測定 が困難である不具合があった。In order to measure brain waves, it is necessary to attach as many as 21 brain wave electrodes to predetermined parts of the head. At this time, in order to reduce the impedance and potential difference between the skin on the head and the electrode, it is necessary to ensure contact between the two. Conventionally, for example, conductive silver paste was applied to the surface of the electrode made of a silver plate. These tapes were attached one by one to the skin of the head at the electroencephalogram measurement point using tape coated with adhesive. Therefore, 2 to 3 hours of preparatory work is required before starting measurement, and the subject is caused considerable pain when attaching and detaching the silver plate. After removing the silver plate, it was necessary to wash the head to remove the silver paste. In addition, the silver plate of the electrode is approximately 1 cm 2 in size, and even if it is pasted with a paste, impurities are likely to be interposed between the plates, resulting in inaccurate measurements. When the skin becomes keratinized, the impedance and potential difference between the skin on the head and the electrode becomes large, making accurate measurement difficult.
【０００３】 そこで、例えば銀ー塩化銀からなる脳波電極と塩化カリなどの電解液を内蔵す る脳波測定用プローブを使用し、プローブ先端から突出して電解液が滲出するチ ップを頭部の脳波測定点に接触させて脳波を測定することが検討されている。こ の電解液による脳波測定方式は、所定個数のホルダーが取り付けられた例えばナ イトキャップ状のプローブ装着具を頭部に被り、このホルダーにプローブをホル ダーに装着すると、複数個のプローブが同時に頭部に接触し、効率良く脳波を測 定することができる。0003 Therefore, for example, a device with a built-in electroencephalogram electrode made of silver-silver chloride and an electrolyte such as potassium chloride can be used. A probe for measuring electroencephalograms is used to detect the electrolyte that protrudes from the tip of the probe and oozes electrolyte. Measurement of brain waves by touching the tip to the brain wave measurement point on the head is being considered. child The electroencephalogram measurement method using an electrolyte solution uses a Place the head cap-like probe attachment device on your head, and hold the probe in this holder. When attached to the head, multiple probes touch the head at the same time, efficiently measuring brain waves. can be determined.

ところで、かかる脳波測定方式において、プローブから出力される脳波信号を 脳波計に送るための例えば２１本の導線が必要になるが、従来は、プローブから 伸び出す導線を束ねて脳波計に接続したり、脳波計に接続された導線の先端にピ ンプラグを取り付け、このピンプラグをホルダーに装着されたプローブに差し込 んで接続していた。しかしながら、例えば２１個ものプローブからそれぞれ導線 が伸び出すと、その取り回しが複雑になり、頭上で導線が交錯して外見上も好ま しくない。そして、導線が引っ張られ易く、プローブのホルダーへの装着操作が 困難である。また、ピンプラグをプローブに差し込むタイプにおいても、多数の ピンプラグを差し込むのに手間を要し、更には、頭に針を刺すイメージがあって 好ましくない。そこで本考案は、簡単な操作でプローブから出力される脳波信号 を脳波計に送ることができ、外見のイメージも良い脳波測定用プローブ装着具を 提供することを目的とするものである。 By the way, in this electroencephalogram measurement method, the electroencephalogram signal output from the probe is For example, 21 conductors are required to send the wires to the electroencephalogram, but conventionally, Bundle the extending wires together and connect them to the electroencephalogram, or attach a pin to the tip of the wire connected to the electroencephalogram. Attach the pin plug and insert this pin plug into the probe attached to the holder. I was connected. However, for example, each conductor from as many as 21 probes As the wires begin to extend, their handling becomes complicated, and the conductors intersect overhead, creating an undesirable appearance. It's not right. Also, the conductor wire is easily pulled, making it difficult to attach the probe to the holder. Have difficulty. In addition, even in the type where the pin plug is inserted into the probe, there are many It takes a lot of effort to insert the pin plug, and what's more, I have the image of sticking a needle in my head. Undesirable. Therefore, the present invention aims to generate electroencephalogram signals output from the probe with simple operation. EEG measurement probe attachment device that can send the brain waves to the electroencephalogram monitor and has a good appearance. The purpose is to provide
