Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement for attaching an electroencephalogram measurement electrode to a scalp, and more particularly to an electroencephalography measurement electrode capable of making it less noticeable that an electroencephalogram measurement electrode is attached to the scalp. The present invention relates to a wig with electrodes.

[0002]

2. Description of the Related Art In measuring human brain waves, a dish electrode is generally used. The dish electrode is brought into contact with the scalp by a conductive paste called a paste. At this time, if there is hair between the scalp and the dish electrode, accurate electroencephalogram measurement may not be performed. Therefore, it is common practice to shave the hair at the electrode mounting site.

[0003]

By the way, when measuring a subject's brain waves, it may be necessary to measure the brain waves as needed. In the case of a dish electrode, it is necessary to make the paste come into contact with the scalp. Therefore, if the dish electrode is attached when it becomes necessary to measure an electroencephalogram, it takes a long time to start the electroencephalogram measurement. For this reason, for subjects who need to measure brain waves at any time,
It is necessary to attach the electrodes. However, in the case of a dish electrode, it is exposed and prominent,
The fact that the dish electrode is always worn poses a problem of subjecting the subject to mental stress. Therefore, for example, when performing electroencephalogram measurement for stress measurement, the mounting of the dish electrode itself becomes stress, and a reaction contrary to the experimenter's intention may occur.

It is an object of the present invention to provide a wig with an electrode for measuring electroencephalogram which can make it less noticeable that the electrode for measuring electroencephalogram is mounted on the head.

In US Pat. No. 4,709,702 and US Pat. No. 5,273,037, a plurality of electrodes for measuring electroencephalograms are attached to a hair band, and a plurality of electrodes can be attached collectively by attaching the hair band to the head. Although such a configuration is described, it is necessary to strongly tighten a hair band in order to bring the electroencephalogram measurement electrode into contact with the scalp, which causes a problem of causing mental and physical pain to the subject.

Therefore, another object of the present invention is to provide a wig with an electrode for measuring electroencephalogram which does not give a subject mental or physical pain when the electrode for measuring electroencephalogram is worn.

[0007]

According to the present invention, there is provided an inner surface of a case having a head adhesive surface at a lower portion, a hair or a hair-like fiber attached to an outer surface, and a hole communicating between the inner and outer surfaces. Another object of the present invention is to provide a wig with an electroencephalogram measurement electrode having a structure in which an electroencephalogram measurement electrode is fixed.

[0008] In this configuration, since the electroencephalogram measurement electrode is hidden by the case where the hair or the like is attached to the outer surface, it is possible to make the electroencephalogram measurement electrode attached inconspicuous.

Further, according to the present invention, the electrode cord for connecting the electrode and the electroencephalograph does not get in the way during non-measurement even when the electrode for measuring electroencephalogram is always worn.
An electrode cord having one end connected to the cord attaching / detaching portion and the other end penetrating the case and connected to the brain wave measuring electrode inside the case was provided.

In this configuration, when the electroencephalogram is not measured, the electrode cord on the electroencephalograph side connected to the electrode cord on the electrode side can be removed by the cord attaching / detaching portion.

Further, in the present invention, in order to make the electrode cord inconspicuous, the electrode cord is made the same color as the hair or hair-like fiber.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is an external perspective view of one embodiment of the present invention, and FIG. 2 is a sectional view of the case 1 shown in FIG.

Hair 2 is attached to the outer surface of the cylindrical portion of the case 1 made of synthetic resin or the like with an adhesive or the like, and a plurality of holes 3 communicating the inside and the outside of the case 1 are formed. Here, the hair 2 is desirably the hair of the person performing the brain wave measurement, but may be another person's hair or artificial hair of the same color as the person's hair. It is also desirable that the hair 2 be densely planted so that the case 1 cannot be seen from the outside. Further, it is preferable that the color of the case 1 be a color close to the scalp.

The outer periphery of the lower surface of the case 1 is a donut-shaped disk portion 5, and the lower surface of the disk portion 5 is coated with an adhesive 6 for bonding the case 1 to the head. The lower surface of the case 1 is an opening 4.

An electrode 7 for measuring an electroencephalogram is provided on the upper inner surface of the case 1.
Is fixed, and a sponge 9 impregnated with a conductive cream is adhered to the lower surface thereof. One end of an electrode cord 8 for connecting the electroencephalogram measurement electrode 7 and the electroencephalograph 13 is connected to the electroencephalogram measurement electrode 7 by soldering. The other end of the electrode cord 8 is connected to the electroencephalograph 13 through the case 1.

When the electroencephalogram measurement electrode 7 is to be mounted on the head of the subject, the case 1 is pressed to the electrode mounting position with the opening 4 of the case 1 down. Thereby, Case 1
Is fixed to the head by the adhesive 6, and the scalp and the electroencephalogram measurement electrode 7 are brought into conduction via the sponge 9. It is desirable that the hair at the electrode mounting position be shaved.

Here, since the electroencephalogram measurement electrode 7 is fixed to the inner surface of the case 1 having the hair 2 mounted on the outer surface, it is not so noticeable that the electroencephalogram measurement electrode 7 is mounted on the head. Can be Case 1
Is provided with a plurality of holes 3, and air flows inside and outside the case 1, so that even when the case 1 is always attached to the head, it is possible to prevent the scalp from becoming stuffy.

The diameter of the electroencephalogram measurement electrode 7 is about 2 cm at most, so that it is slightly larger than that of the case 1. Further, the diameter of the hole 3 for air circulation is about several mm.

FIG. 3 is an external perspective view of another embodiment of the present invention. This embodiment is different from the above-described embodiment in that a cord attaching / detaching portion 10 is connected to the other end of the electrode cord 8 having one end connected to the electroencephalogram measurement electrode 7 in the case 1. The point is that the cord attaching / detaching portion 12 is also connected to one end of the electrode cord 11, and the color of the electrode cord 8 and the cord attaching / detaching portion 10 is the same as the color of the hair 2 attached to the case 1. The length of the electrode cord 8 is desirably about the hair. In FIG. 3, the same reference numerals as those in FIG. 1 represent the same parts.

By adopting such a configuration, the electrode cord 11 on the electroencephalograph 13 side can be detached when the electroencephalogram is not measured, so that the electrode cord does not become an obstacle. Also, when the measurement of the electroencephalogram is started, the electroencephalogram measurement electrode 7 and the electroencephalograph 13 can be connected simply by connecting the cord attaching / detaching portions 10 and 12, so that if the electroencephalogram measurement becomes necessary, EEG measurement can be started.
Furthermore, since the colors of the electrode cord 8 and the cord attaching / detaching portion 10 are the same as the color of the hair 2, the electrode cord can be made inconspicuous.

FIG. 4 shows a state in which a plurality of electroencephalogram electrodes are attached to the head. The electrode for electroencephalogram measurement is attached by pressing the case 1 to the electrode mounting position with the lower surface of the case 1 facing down and bonding the case 1 to the scalp with an adhesive 6. Is hidden by the case 1 to which the hair 2 is attached. Also, since the electrode cord 8 is also the same color as the hair of the subject, it does not stand out. In addition, since the case 1 is adhered to the scalp with the adhesive 6, the electroencephalogram measurement electrode is mounted on the head, so that the subject suffers from mental and physical pain as in the case of using a hair band. I will not give it.

[0023]

As described above, according to the present invention, since the electroencephalogram measurement electrode is fixed to the inner surface of the case where the hair or the like is mounted on the outer surface, the electroencephalogram measurement electrode is mounted on the head. Can be less noticeable. Therefore, even if the electroencephalogram measurement electrode is always worn, mental stress will not be applied to the subject. Therefore, it is very necessary to measure the electroencephalogram as needed, such as stress measurement, electroencephalogram measurement during epilepsy, etc. It is valid. Also,
Since there is a hole communicating between the inside and the outside of the case, it is possible to prevent the scalp from becoming stuffy.

Further, according to the present invention, since the cord attaching / detaching portion is connected to one end of the electrode cord, even when the electrode is always attached, the electrode cord is not obstructed at the time of non-measurement. Can be.

Further, according to the present invention, since the electrode cord is made the same color as the hair, the electrode cord can be made inconspicuous.

Further, the present invention comprises a plurality of cases having hair and the like attached to the outer surface, an electrode for measuring the electroencephalogram fixed to the inner surface, and having a head adhesive surface at the bottom, and a cord attaching / detaching portion at each end. And the other end is provided with an electrode cord connected to the electroencephalogram measurement electrode inside the case, so that it becomes possible to attach a plurality of electroencephalogram measurement electrodes to the head and use a hair band. Unlike the case where the electroencephalogram measurement electrode is worn, the subject does not suffer any physical pain.
