Are attached to the holder at intervals, and are attached to the holder between the receiving optical fiber that receives the reflected light of the inspection light from the subject, and between the irradiation optical fiber and the receiving optical fiber, and contacts the subject. Equipped with an electroencephalograph electrode.

この発明の生体信号処理装置用プローブ装置は、共通のホルダに照射用及び受光用光ファイバと脳波計電極とを取り付け、かつ脳波計電極を照射用光ファイバと受光用光ファイバとの中間でホルダに取り付けたので、計測のためのセッティングに要する手間を軽減しつつ、生体光計測及び脳波計測の両方を行うことができる。   The probe device for a biological signal processing apparatus according to the present invention has a common holder to which irradiation and light receiving optical fibers and an electroencephalograph electrode are attached, and the electroencephalograph electrode is placed between the irradiation optical fiber and the light receiving optical fiber. Therefore, both biological light measurement and electroencephalogram measurement can be performed while reducing the labor required for setting for measurement.

以下、この発明を実施するための最良の形態について、図面を参照して説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

実施の形態１．
図１はこの発明の実施の形態１による生体信号処理装置用プローブ装置を示す断面斜視図であり、図１ではホルダ１の一部を切断して示している。図において、ホルダ１は、被検体（生体）の頭部に装着される。ホルダ１には、例えば遠赤外光等の検査光を頭部に照射する複数の照射用光ファイバ２ａと、検査光の反射光を受光する複数の受光用光ファイバ２ｂとが互いに間隔をおいて配置されている。各照射用光ファイバ２ａは、互いに隣接する受光用光ファイバ２ｂの中間に配置されている。図１では、１個の照射用光ファイバ２ａ及び２個の受光用光ファイバ２ｂのみを示したが、実際には、複数の照射用光ファイバ２ａ及び複数の受光用光ファイバ２ｂが格子状に配置されている。 Embodiment 1 FIG.
FIG. 1 is a cross-sectional perspective view showing a probe device for a biological signal processing apparatus according to Embodiment 1 of the present invention. FIG. In the figure, the holder 1 is attached to the head of a subject (living body). In the holder 1, for example, a plurality of irradiation optical fibers 2 a that irradiate the head with inspection light such as far infrared light and a plurality of light receiving optical fibers 2 b that receive reflected light of the inspection light are spaced apart from each other. Are arranged. Each irradiation optical fiber 2a is disposed in the middle of the light receiving optical fibers 2b adjacent to each other. In FIG. 1, only one irradiation optical fiber 2a and two light receiving optical fibers 2b are shown, but actually, a plurality of irradiation optical fibers 2a and a plurality of light receiving optical fibers 2b are arranged in a lattice shape. Has been placed.

各光ファイバ２ａ，２ｂは、光ファイバ取付具３によりホルダ１に取り付けられている。光ファイバ取付具３には、ファイバ用ばね（図示せず）が内蔵されている。ファイバ用ばねは、光ファイバ２ａ，２ｂが被検体の頭部に押し当てられることにより圧縮される。このとき、ファイバ用ばねの復元力により、光ファイバ２ａ，２ｂの先端部は被検体の頭部に押し付けられる。   Each optical fiber 2 a, 2 b is attached to the holder 1 by an optical fiber attachment 3. The optical fiber fixture 3 has a built-in fiber spring (not shown). The fiber spring is compressed by pressing the optical fibers 2a and 2b against the head of the subject. At this time, the distal ends of the optical fibers 2a and 2b are pressed against the head of the subject by the restoring force of the fiber spring.

ホルダ１には、脳波計測用の複数の脳波計電極４が弾性体としての電極用ばね５を介して取り付けられている。各脳波計電極４は、互いに隣接する照射用光ファイバ２ａと受光用光ファイバ２ｂとの中間に配置されている。さらに詳細には、各脳波計電極４は、互いに隣接する照射用光ファイバ２ａと受光用光ファイバ２ｂとを結ぶ線分の中心又はほぼ中心に配置されている。電極用ばね５は、脳波計電極４が被検体の頭部に押し当てられることにより圧縮される。このとき、電極用ばね５の復元力により、脳波計電極４は被検体の頭部に押し付けられる。   A plurality of electroencephalograph electrodes 4 for electroencephalogram measurement are attached to the holder 1 via electrode springs 5 as elastic bodies. Each electroencephalograph electrode 4 is disposed between the irradiation optical fiber 2a and the light receiving optical fiber 2b adjacent to each other. More specifically, each electroencephalograph electrode 4 is disposed at the center or almost the center of a line segment connecting the irradiation optical fiber 2a and the light receiving optical fiber 2b adjacent to each other. The electrode spring 5 is compressed when the electroencephalograph electrode 4 is pressed against the head of the subject. At this time, the electroencephalograph electrode 4 is pressed against the head of the subject by the restoring force of the electrode spring 5.

次に、動作について説明する。ホルダ１を被検体の頭部に装着することにより、照射用光ファイバ２ａ、受光用光ファイバ２ｂ及び脳波計電極４が同時に被検体の頭部に装着される。そして、適正な計測が行えるように、照射用光ファイバ２ａ、受光用光ファイバ２ｂ及び脳波計電極４と被検体の頭部との接触状態が調整される。この後、照射用光ファイバ２ａを介して被検体の頭部に検査光が照射される。被検体の頭部からの検査光の反射光は、受光用光ファイバ２ｂにより受光され、生体光計測装置本体（図示せず）に送られる。生体光計測装置本体では、受光用光ファイバ２ｂにより送られた反射光から、生体内の生理的変化が計測される。一方、脳波計電極４からの出力信号は、リード線１３（図５参照）を介して脳波計測装置本体（図示せず）に送られる。これにより、脳波計測装置本体では、被検体の脳波が計測される。   Next, the operation will be described. By attaching the holder 1 to the head of the subject, the irradiation optical fiber 2a, the light receiving optical fiber 2b, and the electroencephalograph electrode 4 are simultaneously attached to the subject's head. Then, the contact state of the irradiation optical fiber 2a, the light receiving optical fiber 2b, the electroencephalograph electrode 4 and the head of the subject is adjusted so that appropriate measurement can be performed. Thereafter, the head of the subject is irradiated with the inspection light through the irradiation optical fiber 2a. The reflected light of the inspection light from the head of the subject is received by the light receiving optical fiber 2b and sent to the biological light measuring device main body (not shown). In the living body light measuring device main body, physiological changes in the living body are measured from the reflected light transmitted by the light receiving optical fiber 2b. On the other hand, an output signal from the electroencephalograph electrode 4 is sent to an electroencephalogram measuring device main body (not shown) via a lead wire 13 (see FIG. 5). Thereby, the electroencephalogram of the subject is measured in the electroencephalogram measurement apparatus main body.

このような生体信号処理装置用プローブ装置によれば、照射用光ファイバ２ａ、受光用光ファイバ２ｂ及び脳波計電極４が共通のホルダ１に取り付けられているので、計測のためのセッティングに要する手間を軽減しつつ、生体光計測及び脳波計測の両方を行うことができる。また、生体光計測装置では、照射用光ファイバ２ａと受光用光ファイバ２ｂとの中間位置の脳機能が計測されるが、この例では照射用光ファイバ２ａと受光用光ファイバ２ｂとの中間に脳波計電極４が配置されているので、生体光計測装置による計測位置と脳波計測装置による計測位置とをほぼ一致させることができ、生体光計測装置と脳波計測装置とを組み合わせた全体の計測精度を向上させることができる。   According to such a probe apparatus for a biological signal processing apparatus, the irradiation optical fiber 2a, the light receiving optical fiber 2b, and the electroencephalograph electrode 4 are attached to the common holder 1, so that labor required for setting for measurement is required. Both biological light measurement and electroencephalogram measurement can be performed while reducing the above. In the biological light measurement device, the brain function at an intermediate position between the irradiation optical fiber 2a and the light receiving optical fiber 2b is measured. In this example, the brain function is intermediate between the irradiation optical fiber 2a and the light receiving optical fiber 2b. Since the electroencephalograph electrode 4 is arranged, the measurement position by the biological light measurement device and the measurement position by the electroencephalogram measurement device can be substantially matched, and the total measurement accuracy combining the biological light measurement device and the electroencephalogram measurement device Can be improved.

さらに、この例では、脳波計電極４が電極用ばね５を介してホルダ１に取り付けられているので、脳波計電極４を被検体の頭部にしっかりと接触させることができ、脳波を安定して計測することができる。   Furthermore, in this example, since the electroencephalograph electrode 4 is attached to the holder 1 via the electrode spring 5, the electroencephalograph electrode 4 can be firmly brought into contact with the head of the subject, and the electroencephalogram can be stabilized. Can be measured.

実施の形態２．
次に、図２はこの発明の実施の形態２による生体信号処理装置用プローブ装置を示す断面斜視図である。図において、各ファイバ取付具３には、可視光を反射する材料からなるファイバ用反射部材６が貼り付けられている。また、ホルダ１の脳波計電極４の取付位置には、可視光を反射する材料からなる電極用反射部材７が貼り付けられている。他の構成は、実施の形態１と同様である。 Embodiment 2. FIG.
Next, FIG. 2 is a cross-sectional perspective view showing a biological signal processing device probe apparatus according to Embodiment 2 of the present invention. In the figure, a fiber reflection member 6 made of a material that reflects visible light is attached to each fiber fixture 3. An electrode reflection member 7 made of a material that reflects visible light is attached to the attachment position of the electroencephalograph electrode 4 of the holder 1. Other configurations are the same as those in the first embodiment.

このような生体信号処理装置用プローブ装置では、二次元で撮影できるＣＣＤカメラ等の撮影装置によりホルダ１を撮影することにより、ファイバ用反射部材６及び電極用反射部材７の互いの相対的な位置を求める。これにより、照射用光ファイバ２ａ、受光用光ファイバ２ｂ及び脳波計電極４の計測位置を、個々に実測することなく、容易に把握することができる。従って、計測のためのセッティングに要する手間を軽減することができる。   In such a probe device for a biological signal processing device, the relative position of the reflective member 6 for a fiber and the reflective member 7 for an electrode is obtained by photographing the holder 1 with a photographing device such as a CCD camera capable of photographing in two dimensions. Ask for. Thereby, it is possible to easily grasp the measurement positions of the irradiation optical fiber 2a, the light receiving optical fiber 2b, and the electroencephalograph electrode 4 without actually measuring them individually. Therefore, the labor required for setting for measurement can be reduced.

なお、複数の撮影装置で互いに異なる角度からホルダ１を撮影することにより、照射用光ファイバ２ａ、受光用光ファイバ２ｂ及び脳波計電極４の三次元的な計測位置を把握するようにしてもよい。
また、ファイバ用反射部材６と電極用反射部材７とを、互いに異なる色としたり、互いに異なる形状としたりして、容易に識別できるようしてもよい。
さらに、照射用光ファイバ２ａに対応したファイバ用反射部材６と受光用光ファイバ２ｂに対応したファイバ用反射部材６とを、互いに異なる色としたり、互いに異なる形状としたりして、容易に識別できるようしてもよい。 In addition, you may make it grasp | ascertain the three-dimensional measurement position of the optical fiber 2a for irradiation, the optical fiber 2b for light reception, and the electroencephalograph electrode 4 by image | photographing the holder 1 from a mutually different angle with a some imaging device. .
Moreover, the reflective member 6 for a fiber and the reflective member 7 for an electrode may be made to be easily distinguishable by using different colors or different shapes.
Further, the fiber reflecting member 6 corresponding to the irradiation optical fiber 2a and the fiber reflecting member 6 corresponding to the light receiving optical fiber 2b can be easily identified by making them different colors or different shapes. You may do it.

実施の形態３．
次に、図３はこの発明の実施の形態３による生体信号処理装置用プローブ装置の要部を示す斜視図、図４は図３の光ファイバの先端部を示す底面図である。図において、照射用光ファイバ２ａ及び受光用光ファイバ２ｂの先端部は、例えば銅又は黄銅等の導電性の材料からなるスリーブ部材８により囲繞されている。スリーブ部材８は、照射用光ファイバ２ａ及び受光用光ファイバ２ｂの先端部に固定されている。 Embodiment 3 FIG.
Next, FIG. 3 is a perspective view showing a main part of a probe device for a biological signal processing apparatus according to Embodiment 3 of the present invention, and FIG. 4 is a bottom view showing a tip portion of the optical fiber of FIG. In the figure, the distal ends of the irradiation optical fiber 2a and the light receiving optical fiber 2b are surrounded by a sleeve member 8 made of a conductive material such as copper or brass. The sleeve member 8 is fixed to the distal ends of the irradiation optical fiber 2a and the light receiving optical fiber 2b.

スリーブ部材８と光ファイバ２ａ，２ｂとの間には、導電性の液体が含浸された液体保持部材９が充填されている。導電性の液体としては、例えば生理食塩水が用いられる。液体保持部材９としては、例えばスポンジ等の多孔質部材が用いられる。脳波計電極１０は、スリーブ部材８及び液体保持部材９を有している。また、脳波計電極１０は、リード線を介して脳波計測装置本体に接続されている。光ファイバ２ａ，２ｂは、ファイバ取付具３によりホルダ１（図１参照）に取り付けられている。   A liquid holding member 9 impregnated with a conductive liquid is filled between the sleeve member 8 and the optical fibers 2a and 2b. As the conductive liquid, for example, physiological saline is used. As the liquid holding member 9, for example, a porous member such as a sponge is used. The electroencephalograph electrode 10 includes a sleeve member 8 and a liquid holding member 9. Further, the electroencephalograph electrode 10 is connected to the electroencephalogram measuring apparatus main body via a lead wire. The optical fibers 2a and 2b are attached to the holder 1 (see FIG. 1) by a fiber attachment 3.

このような生体信号処理装置用プローブ装置によれば、生体光計測用の光ファイバ２ａ，２ｂの先端部に脳波計電極１０を一体に設けたので、光ファイバ２ａ，２ｂを被検体の頭部に接触させることにより、脳波計電極１０も同時に被検体の頭部に接触させることができ、計測のためのセッティングに要する手間を軽減することができる。   According to such a probe device for a biological signal processing apparatus, since the electroencephalograph electrode 10 is integrally provided at the distal ends of the optical fibers 2a and 2b for measuring biological light, the optical fibers 2a and 2b are connected to the head of the subject. The electroencephalograph electrode 10 can be brought into contact with the head of the subject at the same time, and the labor required for setting for measurement can be reduced.

実施の形態４．
次に、図５はこの発明の実施の形態４による生体信号処理装置用プローブ装置を示す側面図である。図において、紐状（又はネット状）のホルダ１１は、被検体の頭部に装着される。ホルダ１１には、複数の照射用光ファイバ２ａ、複数の受光用光ファイバ２ｂ、及び複数の脳波計電極４が取り付けられている。各光ファイバ２ａ，２ｂは、ファイバ取付具１２によりホルダ１１に取り付けられている。ファイバ取付具１２には、ホルダ１１を構成する紐を通すためのスリット（図示せず）が設けられている。即ち、ファイバ取付具１２は、ホルダ１１の紐をスリットに通すことによりホルダ１１に取り付けられている。各脳波計電極４は、互いに隣接する照射用光ファイバ２ａと受光用光ファイバ２ｂとの中間に配置されている。また、各脳波計電極４は、リード線１３を介して脳波計測装置本体に接続されている。 Embodiment 4 FIG.
5 is a side view showing a probe apparatus for a biological signal processing apparatus according to Embodiment 4 of the present invention. In the figure, a string-like (or net-like) holder 11 is attached to the head of a subject. A plurality of irradiation optical fibers 2 a, a plurality of light receiving optical fibers 2 b, and a plurality of electroencephalograph electrodes 4 are attached to the holder 11. Each of the optical fibers 2 a and 2 b is attached to the holder 11 by a fiber attachment 12. The fiber fixture 12 is provided with a slit (not shown) for passing a string constituting the holder 11. That is, the fiber fixture 12 is attached to the holder 11 by passing the string of the holder 11 through the slit. Each electroencephalograph electrode 4 is disposed between the irradiation optical fiber 2a and the light receiving optical fiber 2b adjacent to each other. Each electroencephalograph electrode 4 is connected to the electroencephalogram measurement apparatus main body via a lead wire 13.

このような生体信号処理装置用プローブ装置では、脳波計電極４装着用のホルダ１１の紐に光ファイバ２ａ，２ｂを取り付けられるようにしたので、計測のためのセッティングに要する手間を軽減しつつ、生体光計測及び脳波計測の両方を行うことができる。   In such a probe device for a biological signal processing apparatus, the optical fibers 2a and 2b can be attached to the string of the holder 11 for attaching the electroencephalograph electrode 4, while reducing the labor required for setting for measurement, Both biological light measurement and electroencephalogram measurement can be performed.

実施の形態５．
次に、図６はこの発明の実施の形態５による生体信号処理装置用プローブ装置を示す側面図である。図において、照射用光ファイバ２ａ及び受光用光ファイバ２ｂは、ファイバ取付具１４によりホルダ１１に取り付けられている。ファイバ取付具１４のホルダ１１への取付構造は、脳波計電極４のホルダ１１への取付構造と同様になっている。 Embodiment 5. FIG.
Next, FIG. 6 is a side view showing a probe apparatus for a biological signal processing apparatus according to Embodiment 5 of the present invention. In the figure, an irradiation optical fiber 2 a and a light receiving optical fiber 2 b are attached to a holder 11 by a fiber attachment 14. The attachment structure of the fiber attachment 14 to the holder 11 is the same as the attachment structure of the electroencephalograph electrode 4 to the holder 11.

このように、脳波計電極４及び光ファイバ２ａ，２ｂのホルダ１１への取付構造を互いに同じにすることにより、全体の構造を簡単にすることができ、計測のためのセッティングに要する手間を軽減することができる。   Thus, by making the attachment structure of the electroencephalograph electrode 4 and the optical fibers 2a and 2b to the holder 11 the same, the entire structure can be simplified, and the labor required for setting for measurement is reduced. can do.

実施の形態６．
次に、図７はこの発明の実施の形態６による生体信号処理装置用プローブ装置を示す側面図、図８は図７の要部を示す底面図である。図において、照射用光ファイバ２ａ及び受光用光ファイバ２ｂは、ゲル状のファイバ用ホルダ（保護ゲル）１５にファイバ取付具１６を介して取り付けられている。ゲル状のファイバ用ホルダ１５は、被検体の頭部の少なくとも一部を面で覆うものである。 Embodiment 6 FIG.
Next, FIG. 7 is a side view showing a probe device for a biological signal processing apparatus according to Embodiment 6 of the present invention, and FIG. 8 is a bottom view showing the main part of FIG. In the figure, an irradiation optical fiber 2 a and a light receiving optical fiber 2 b are attached to a gel-like fiber holder (protective gel) 15 via a fiber attachment 16. The gel-like fiber holder 15 covers at least a part of the head of the subject with a surface.

脳波計電極４は、電極用ホルダとしての紐状（又はネット状）のホルダ１１に取り付けられている。ファイバ用ホルダ１５には、脳波計電極４に係合する電極係合部として、脳波計電極４の側面部を囲繞する複数の電極囲繞部１５ａが設けられている。また、各電極囲繞部１５ａには、紐状のホルダ１１を逃がす複数のスリット１５ｂが設けられている。   The electroencephalograph electrode 4 is attached to a string-like (or net-like) holder 11 as an electrode holder. The fiber holder 15 is provided with a plurality of electrode surrounding portions 15 a surrounding the side surface portion of the electroencephalograph electrode 4 as electrode engaging portions that engage with the electroencephalograph electrode 4. Each electrode surrounding portion 15a is provided with a plurality of slits 15b through which the string-like holder 11 is released.

このような生体信号処理装置用プローブ装置では、照射用光ファイバ２ａ及び受光用光ファイバ２ｂは、ファイバ用ホルダ１５に予め取り付けられている。また、脳波計電極４は、紐状のホルダ１１に取り付けられている。光ファイバ２ａ，２ｂ及び脳波計電極４を被検体の頭部に配置する場合、まず紐状のホルダ１１を頭部に装着し、その上から紐状のホルダ１１を覆うようにファイバ用ホルダ１５を頭部に装着する。このとき、電極囲繞部１５ａに脳波計電極４を嵌合する。   In such a probe device for a biological signal processing apparatus, the irradiation optical fiber 2 a and the light receiving optical fiber 2 b are attached to the fiber holder 15 in advance. The electroencephalograph electrode 4 is attached to a string-like holder 11. When the optical fibers 2a and 2b and the electroencephalograph electrode 4 are arranged on the head of the subject, first, the fiber holder 15 is attached so that the string-shaped holder 11 is attached to the head and the string-shaped holder 11 is covered from above. On the head. At this time, the electroencephalograph electrode 4 is fitted to the electrode surrounding portion 15a.

このように、ゲル状のファイバ用ホルダ１５で外周部を覆うことにより、被検体が寝たままの状態で計測を行う際に、被検体が寝返りをうった場合などに、光ファイバ２ａ，２ｂ及び脳波計電極４の位置ずれを防止することができる。特に、この例では、脳波計電極４を囲繞する電極囲繞部１５ａを設けたので、ファイバ用ホルダ１５に直接取り付けられた光ファイバ２ａ，２ｂだけでなく、紐状のホルダ１１に取り付けられた脳波計電極４の位置ずれもより確実に防止することができる。従って、計測のためのセッティングに要する手間を軽減しつつ、生体光計測及び脳波計測の両方を行うことができる。   Thus, by covering the outer periphery with the gel-like fiber holder 15, the optical fibers 2a and 2b are used when the subject lies down when performing measurement while the subject is lying. Further, the positional deviation of the electroencephalograph electrode 4 can be prevented. In particular, in this example, since the electrode surrounding portion 15 a surrounding the electroencephalograph electrode 4 is provided, not only the optical fibers 2 a and 2 b directly attached to the fiber holder 15 but also the electroencephalogram attached to the string-like holder 11.
