【発明の属する技術分野】
本発明は被検者の頭部の診断装置に関する。特に被検者の頭部頭髪を避けて計測を容易化できる計測装置に関する。特には、生体光計測を利用した診断において、計測器具としてのプローブの装着の操作等を容易化するのに好適な生体光計測装置に関する。
【0002】
【従来の技術】
頭部の計測を行う場合、たとえば生体光計測を利用した診断では、頭部に固定されたホルダに取り付けられているソケットにプローブを装着する。このとき、被検者の頭皮とホルダの間に被検者の頭髪が挟みこまれてしまうと頭部への入力情報や頭部からの出力情報が減衰して正確な診断ができない。
【0003】
図5は従来の計測装置を示したものである。図中、1はソケット、4はソケット1に施された穴、5は除外した頭髪の収納部分、6は計測器具、8は被検者の頭皮、9は被検者の頭髪、10は小型の杓子状の器具をそれぞれ示す。従来の技術では、計測器具を装着する際に小型の杓子状の器具10を使い計測箇所毎に頭髪を除外しながら計測器具6を頭皮に接触させて計測を行っている。
また、生体光計測に限らず、頭部に計測器具を接触させて計測する場合や頭部に近接させて計測する場合においても、小型の杓子状の器具を用いて頭髪をいちいち掻き分けながら計測をおこなうことは、計測の効率を大幅に悪化させることになり、検査者の操作時間や診断時間が長くなり、被検者の束縛時間が増え被検者の負担が増えるなどその他の問題も引き起こしていた。
【0004】
たとえば[特許文献1]では、プローブケースを揺動することで、頭髪をかきわけることができる構成を開示しているが、髪質や髪の量によっては頭髪を充分かきわけることができない。このような場合、髪の毛を一本一本確実にかき分けるには上述のような小型の杓子状の器具を用いざるを得なかった。

【発明が解決しようとする課題】
本発明の課題は計測器具、特に生体光測定用プローブ先端部や脳波測定用の電極プローブを頭皮に安定して密着させ、計測の精度や計測条件の安定性を向上できる計測装置を提供することである。
また、さらに髪を一本一本かき分けずとも、まとめて一気にかき分けて直ぐ後に計測器具を被検者の頭皮に密着できる計測装置を提供することである。
【0007】
【課題を解決するための手段】
本願発明によれば、計測器具および上記計測器具を装着して頭部に固定するホルダを有しており、上記計測器具によって被検者の頭部を計測する計測装置において、上記計測器具が配置される位置に対応する部分の頭部頭髪をかき分ける機構をさらに備えた上記計測装置を提供する。
【0008】
【発明の実施の形態】
以下図面を参照して本発明の実施例を説明する。
図1は本発明の一実施例による計測器具6としてのプローブ装着前の状態を示す断面図である。また、図2は本発明の一実施例による計測器具6としてのプローブ装着後の状態を示す断面図である。図3は本発明の一実施例による計測器具装着前の状態を示す部分破断斜視図である。また、図4は本発明の一実施例による計測器具装着後の状態を示す部分破断斜視図である。

図中、1はソケット、2は頭髪除外用爪、3は頭髪除外用爪2の支点、4はソケット1に施された穴、5は除外した頭髪の収納部分、6は計測器具、7はばね、8は被検者の頭皮、9は被検者の頭髪をそれぞれ示す。穴4の側部には支点3に支えられ、かつ、ばね7によって上方向に付勢された爪2が設けられている。
【0010】
上記計測器具6は、例えば生体光計測装置用のプローブや生体脳波計測用の電極プローブである。生体光計測装置は複数の光照射プローブと複数の光検出プローブとを頭皮上に配置して、照射プローブから照射した近赤外光が多数回散乱されながら大脳皮質まで達して、頭皮上に戻ってきた反射光を光検出プローブで検出することにより、頭皮下の大脳表面を含む部位の血液量の変化量を主とする生体反応の計測に用いる。たとえば、頭皮上に照射した近赤外光を約3cm離れた位置で検出した光の強度により頭表から20mm前後の深さの大脳表面部位の血液量の変化を測定できる。
【0011】
上記爪2は上述したとおり上方向に付勢されているため、図1および図3においては穴4内に突出している。計測器具6を上記穴4に挿入すると、図2及び図4に示すように、爪2は下に押しやられて、爪2の先端は穴4の直下の頭髪9をかき分けながら、除外した頭髪の収納部分5に頭髪を追いやって、穴4直下の頭皮を露出させる。これと同時に計測器具6は露出した頭皮8に接して計測を待つこととなる。爪2は被検者の頭皮7に直接触れるものなので、頭皮を傷つけない材料や形状であることが要求される。たとえば、爪2の先端は丸みを帯びていることが望ましく、材質は硬度の低い樹脂などが望ましい。また爪の間に頭髪を巻き込んで絡めてしまうことがないような形状が望ましい。具体的には、図3と4中、複数の爪2の交差する部分の隙間が髪の毛の太さより狭ければ髪の毛の噛みこみを防止して、被検者はより快適に検査を受けることができる。髪の毛の太さには個人差があるが、たとえば0.01mm以下の上記隙間とすれば、髪の毛の噛み込みはかなりの程度防止できる。この隙間は組み立て精度や上記爪の寸法精度を向上することで達成可能である。
【0012】
計測終了後にプローブ6をソケット1から、取り外すと、ばね7の反力で爪2が元の状態にもどり、図1および図3の状態に戻る。このように計測器具を穴に挿入して計測位置にセットする際、爪2が同時に頭髪9をかき分けるためワンアクションで計測位置のセットと頭髪のかきわけが実現できる。
【0013】
【発明の効果】
本発明は上述のように、ソケット1内部にプローブ等計測器具の挿入によって稼動する爪状の頭髪除外機構2を備える構成にしたものである。上記構成にしたことにより、被検者頭部の生体光計測や生体脳波計測時に計測器具を正確に、かつ、容易に取り付けることができるので、検査者の操作時間、被検者の診断時間と負担が軽減される。特に生体光計測診断のソケットとプローブの装着に際しては、充分確実に頭髪を避けてプローブを頭皮に密着可能であるため大きな効果を発揮する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a diagnostic device for a subject's head. In particular, the present invention relates to a measurement device capable of avoiding the head hair of a subject to facilitate measurement. In particular, the present invention relates to a biological light measurement device suitable for facilitating the operation of mounting a probe as a measuring instrument in diagnosis using biological light measurement.
[0002]
[Prior art]
When measuring the head, for example, in a diagnosis using living body light measurement, a probe is mounted on a socket attached to a holder fixed to the head. At this time, if the hair of the subject is sandwiched between the scalp of the subject and the holder, input information to the head and output information from the head are attenuated, and accurate diagnosis cannot be performed.
[0003]
FIG. 5 shows a conventional measuring device. In the figure, 1 is a socket, 4 is a hole formed in the socket 1, 5 is a part for storing hair, 6 is a measuring instrument, 8 is the scalp of the subject, 9 is the hair of the subject, and 10 is a small size. Each shows a scoop-like instrument. In the related art, measurement is performed by using a small scoop-shaped instrument 10 when the measuring instrument 6 is attached to the scalp while excluding the hair at each measurement location.
In addition to measurement of living body light, even when measuring by bringing a measuring instrument into contact with the head or when measuring close to the head, the measurement is performed using a small scoop-like instrument while scraping the hair one by one. Doing so significantly reduces the efficiency of measurement, increases the operation time and diagnostic time of the examiner, and also causes other problems, such as increased restraint time for the subject and increased burden on the subject. Was.
[0004]
For example, Patent Document 1 discloses a configuration in which the hair can be separated by swinging the probe case, but the hair cannot be sufficiently separated depending on the hair quality and the amount of hair. In such a case, in order to surely separate the hairs one by one, the above-mentioned small scoop-shaped instrument has to be used.
[0005]

[Problems to be solved by the invention]
An object of the present invention is to provide a measuring device which can stably adhere a measuring instrument, in particular, a probe for biological light measurement or an electrode probe for measuring an electroencephalogram to the scalp, and improve measurement accuracy and stability of measurement conditions. It is.
It is another object of the present invention to provide a measuring device that can closely contact a measuring instrument with the scalp of a subject immediately after slicing the hair at once without having to slash the hair one by one.
[0007]
[Means for Solving the Problems]
According to the invention of the present application, the measuring instrument has a holder for mounting the measuring instrument and fixing the measuring instrument to the head, and the measuring instrument is arranged in a measuring device that measures the head of the subject with the measuring instrument. The measuring device further comprises a mechanism for pushing out the head hair of a portion corresponding to the position to be measured.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a sectional view showing a state before mounting a probe as a measuring instrument 6 according to an embodiment of the present invention. FIG. 2 is a sectional view showing a state after mounting a probe as a measuring instrument 6 according to an embodiment of the present invention. FIG. 3 is a partially broken perspective view showing a state before mounting a measuring instrument according to an embodiment of the present invention. FIG. 4 is a partially broken perspective view showing a state after mounting the measuring instrument according to one embodiment of the present invention.
[0009]
In the figure, 1 is a socket, 2 is a nail for removing the hair, 3 is a fulcrum of the nail for removing the hair 2, 4 is a hole formed in the socket 1, 5 is a storage portion of the removed hair, 6 is a measuring instrument, and 7 is a measuring instrument. A spring, 8 indicates the scalp of the subject, and 9 indicates the hair of the subject. On the side of the hole 4 is provided a pawl 2 supported by the fulcrum 3 and urged upward by a spring 7.
[0010]
The measuring instrument 6 is, for example, a probe for a biological light measuring device or an electrode probe for measuring a living brain wave. The biological optical measurement device arranges multiple light irradiation probes and multiple light detection probes on the scalp, and the near infrared light emitted from the irradiation probe reaches the cerebral cortex while being scattered many times and returns to the scalp The reflected light detected by the light detection probe is used for measuring a biological reaction mainly based on a change in blood volume in a region including the cerebral surface under the head. For example, a change in blood volume at the cerebral surface at a depth of about 20 mm from the front of the head can be measured based on the intensity of light detected at a position about 3 cm away from near-infrared light irradiated on the scalp.
[0011]
Since the claw 2 is urged upward as described above, it protrudes into the hole 4 in FIGS. 1 and 3. When the measuring instrument 6 is inserted into the hole 4, as shown in FIGS. 2 and 4, the nail 2 is pushed down, and the tip of the nail 2 separates the hair 9 immediately below the hole 4 while removing the hair 9 removed. The hair is driven into the storage part 5 to expose the scalp immediately below the hole 4. At the same time, the measuring instrument 6 comes into contact with the exposed scalp 8 and waits for measurement. Since the nail 2 directly touches the scalp 7 of the subject, it is required that the nail 2 be made of a material or shape that does not damage the scalp. For example, the tip of the nail 2 is preferably rounded, and the material is desirably a resin having low hardness. It is also desirable that the shape be such that the hair does not get entangled between the nails. Specifically, in FIGS. 3 and 4, if the gap at the intersection of the plurality of claws 2 is smaller than the thickness of the hair, the hair can be prevented from biting and the subject can be more comfortably examined. it can. Although there are individual differences in the thickness of the hair, for example, if the gap is 0.01 mm or less, biting of the hair can be prevented to a considerable extent. This gap can be achieved by improving the assembly accuracy and the dimensional accuracy of the claw.
[0012]
When the probe 6 is removed from the socket 1 after the measurement is completed, the claw 2 returns to the original state by the reaction force of the spring 7, and returns to the state of FIGS. Thus, when the measuring instrument is inserted into the hole and set at the measurement position, the nail 2 simultaneously separates the hair 9, so that the setting of the measurement position and the separation of the hair can be realized by one action.
[0013]
【The invention's effect】
As described above, the present invention has a configuration in which the claw-shaped hair removal mechanism 2 that is activated by inserting a measuring instrument such as a probe into the socket 1 is provided. With the above configuration, the measuring instrument can be accurately and easily attached at the time of measuring the living body light or the living body electroencephalogram of the subject's head, so that the operation time of the examiner, the diagnosis time of the subject, and The burden is reduced. In particular, when mounting the socket and the probe for living body optical measurement diagnosis, the probe can be brought into close contact with the scalp while avoiding the hair sufficiently sufficiently, so that a great effect is exhibited.
