Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electrode attachment device for electroencephalogram measurement used when attaching a needle electrode for electroencephalogram measurement to a human head.

[Prior Art] This type of conventional electrode mounting device for electroencephalogram measurement has a needle electrode fixed in advance to a desired position on a cap.

[Problem that the invention aims to solve] In the conventional electrode attachment device for electroencephalogram measurement, the needle electrode is fixed to the cap, so even though only the needle electrode needs to be replaced after the test, the cap must also be discarded. This method is not only uneconomical, but also has the problem that since the needle electrode is fixed to the cap in advance, the needle electrode is placed in an unnecessary location during the examination, making it uneconomical.

This idea was made to solve this problem.By making the needle electrode separate from the foam molding and making it removable, it is possible to dispose of only the needle electrode, and the needle electrode can be fixed only where it is needed. The purpose of the present invention is to obtain an electrode attachment device for electroencephalogram measurement that is both easy to use and economical.

[Means for Solving the Problem] In order to achieve the above object, the electroencephalogram measurement electrode attachment device according to the present invention includes a foam molded body formed in an inverted bowl shape and provided with a plurality of needle insertion holes. , a stopper for fixing the foam molded body to the head, and a plurality of electroencephalogram measurement needles each having a double-sided adhesive tape attached to the lower surface thereof and removably attached to the outer surface of the foam molded body using the double-sided adhesive tape. It is equipped with an electrode.

Further, the electrode fitting for electroencephalogram measurement according to this invention has holes for needle insertion arranged in parallel in the foamed molded body, and is equipped with electrode holders whose both ends are fixed to the edges of the foamed molded body, respectively. .

[Function] In this invention, the needle electrode and the foamed molded body are separate and removable, so the needle electrode can be fixed to the required location on the foamed molded body at the site before inspection.
After the test, the needle electrode can be removed from the foam molding and thrown away.

Further, with this invention, the needle electrodes can be held together in rows by the electrode presser fixed to the foamed molded body.

[Embodiment] An embodiment of this invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a side view of the test state (excluding lead wires), FIG. 2 is an overhead view of FIG. 1, and FIG. 3 is an enlarged sectional view of the electrode portion. In the figure, reference numeral 1 denotes a foamed molded product formed into an inverted bowl shape capable of covering a human head 2, and is an inverted bowl-shaped foamed polyethylene molded product molded from foamed polyethylene to a thickness of 1 to 5 mm. Reference numeral 3 denotes a stopper for fixing the foamed molded article 1 to the head 2, which is a stopper band designed to be hung on the chin. Reference numeral 4 designates a desired number of needle insertion holes provided in the foam molded body 1, and 5 designates needle electrodes that are detachably attached to the positions of the needle insertion holes 4 from the outside, and are inserted into the needle insertion holes 4. It is composed of a needle 5a that is attached to the needle 5a, and a holding member 5b for the needle 5a. The holding member 5b is removably attached to the outer surface of the foamed molded body 1 with an annular double-sided adhesive tape 502 on the lower surface. The midsection of the needle 5a is covered with metal 503, and the holding member 5b is a colored plastic molded product, so that the hole 501 of the needle 5a
The needle 5a is firmly held and the direction of the needle 5a is stabilized. Reference numeral 6 denotes a plastic presser for fixing the needle electrode 5;
It has a hole 6a through which it passes, and both ends are fixed to the edges of the foamed molded body 1. Since the holding member 5b of the needle electrode 5 is held down by this presser 6, the needle 5a
is also pressed against the scalp and fixed. A lead wire 7 with a clip is attached to the needle 5a of the needle electrode 5, and is connected to an electroencephalogram tester (not shown).

By making the needle electrode 5 separate from the foam molding 1 and making it detachable from the outer surface of the foam molding 1 using the double-sided adhesive tape 502 in this way, it is possible to measure only the necessary parts of the foam molding 1 at the site before inspection. Since the needle electrode 5 can be firmly fixed to the needle electrode 5, the needle electrode 5 can be kept to the minimum necessary, making it economical. Furthermore, after the inspection, the needle electrode 5 can be removed from the foamed molded body 1 and replaced with a new one, so the foamed molded body 1 can be used as many times as needed without being thrown away. This is advantageous from a sanitary and safety standpoint.

In the above embodiment, the needle 5a fitted into the hole 501 of the holding member 5b is shown as the needle electrode 5, but if the needle 5a is inserted into the hole 501 of the holding member 5b in a state that cannot be reversed, the presser There is no need to press it down.

Further, in the above embodiment, a foamed polyethylene molded product is shown as the foamed molded product 1, but it may also be a foamed molded product made of various plastics such as vinyl chloride, polyurethane, and various rubbers, and may have different sizes and shapes during molding. By molding several types, they can be used by everyone from children to adults. Furthermore, the fastener 3 may be a velvet fastener instead of a fastening band.

In addition, if the needle insertion holes 4 are provided in parallel in the foamed molded body 1 as in the above embodiment, and the electrode pressers 6 are provided with both ends fixed to the edges of the foamed molded body 1, the foamed molded body 1 can be easily formed. The needle electrodes 5 arranged in parallel on the body 1 can be pressed together in rows.

[Effects of the invention] As described above, according to this invention, only the needle electrodes can be made disposable, and the needle electrodes can be fixed only to the necessary parts of the foamed molded body, which makes it economical.
