Description

本発明は、例えば内臓や皮下の脂肪組織を測定することができる、位置決めガイド部を備えた測定装置に関する。   The present invention relates to a measuring apparatus including a positioning guide unit that can measure, for example, internal organs or subcutaneous adipose tissue.

よく知られているように、体幹の内臓脂肪組織や皮下脂肪組織は、腹部に配置した電極によって測定されるインピーダンス情報と身体特定化情報とから推定することができる。図7、図8に、この原理を用いた従来の測定装置の外観とその使用法をそれぞれ示す。   As is well known, the visceral adipose tissue and subcutaneous adipose tissue of the trunk can be estimated from impedance information measured by electrodes placed on the abdomen and body specific information. 7 and 8 show the appearance of a conventional measuring apparatus using this principle and how to use it.

この従来装置3は、主に、本体部50と、電線120L、120Rを介してこの本体部50に接続された2つのグリップ電極部130、140から成る。本体部50は、例えば、その表面52に操作入力部51や表示部53を有し、その内部に演算制御部や記憶部(図示されていない)を有する。   This conventional device 3 mainly includes a main body 50 and two grip electrode portions 130 and 140 connected to the main body 50 via electric wires 120L and 120R. The main body 50 has, for example, an operation input unit 51 and a display unit 53 on the surface 52 thereof, and an arithmetic control unit and a storage unit (not shown) therein.

各グリップ電極部130、140の接触面には、下段に、電流印加電極13R1、13L1と電圧計測電極14R1、14L1とが、上段に、電圧計測電極14R2、14L2が、それぞれ設けてある。 On the contact surfaces of the grip electrode portions 130 and 140, the current application electrodes 13R 1 and 13L 1 and the voltage measurement electrodes 14R 1 and 14L 1 are arranged in the lower stage, and the voltage measurement electrodes 14R 2 and 14L 2 are arranged in the upper stage, respectively. It is provided.

グリップ電極部130、140は、ハンディタイプのものであり、図6に示すように、グリップ電極部130、140を各手に持って、それらを被験者の測定部位、例えば、腹部に押し当てて使用する。このとき、被験者において各電極を押し当てる位置は、例えば、臍Aを目安として判断されることになる。   The grip electrode portions 130 and 140 are of the handy type. As shown in FIG. 6, the grip electrode portions 130 and 140 are held in each hand and are used by pressing them against the measurement site of the subject, for example, the abdomen. To do. At this time, the position where each electrode is pressed in the subject is determined using, for example, the navel A as a guide.

しかしながら、インピーダンス情報をより正確に得るためには、電極を腹部のより正確な位置に位置決めする必要がある。上述した従来構成では、電極配置位置が被験者等の主観によって判断される傾向があり、正確な位置決めを行うことができなかった。   However, in order to obtain impedance information more accurately, it is necessary to position the electrode at a more accurate position of the abdomen. In the conventional configuration described above, the electrode arrangement position tends to be determined by the subject's subjectivity, and accurate positioning cannot be performed.

本発明の目的は、これら従来技術における問題点を解消することにあり、電極の正確な位置決めを可能とする位置決めガイド部を備えた測定装置を提供することを目的とする。   An object of the present invention is to solve these problems in the prior art, and an object of the present invention is to provide a measuring apparatus including a positioning guide portion that enables accurate positioning of electrodes.

Two electrode supports to be supported, and one of the electrode supports includes one current application electrode of the current application electrode pair and one voltage measurement electrode of the voltage measurement electrode pair. The trunk on the section between the umbilicus and the upper edge of the iliac crest, or the connecting tendon between the rectus abdominis and external oblique muscles, located on either the left or right side when viewed from the umbilicus in the direction Positioned at a distance in the longitudinal direction, the other of the electrode support is on the other side when the other current application electrode and the other voltage measurement electrode are viewed around the umbilicus in the trunk periphery direction. The section between the umbilicus and the upper edge of the iliac crest, or the rectus abdominis and the outside The coupling tendon between oblique muscle, and positioned at a distance in the trunk longitudinal direction, each of the electrode supporting member, the positioning guide for positioning a position in the subject of the electrodes collide with some portion of the subject It features a measuring device for measuring visceral or subcutaneous adipose tissue provided with a section.

上記測定装置において、前記電極支持体は、前記装置の左右各側にこれら左右各側方向においてスライド可能に設けられていてもよい。 In the measuring apparatus, the electrode support may be slidably provided on the left and right sides of the apparatus in the left and right directions.

It may be slid.

図1に、本発明の一実施形態による、位置決めガイド部を備えた測定装置の外観斜視図を示す。本装置1は、被験者の腹部形状に適合するように多少湾曲させた本体部10と、この本体部10に対して多少折れ曲がることができるように、例えば蝶番式に、本体部10の左右各側に可動状態で設けられた電極支持部12R、12Lから成る。この装置1は図示のように、ハンディタイプのものであってもよく、例えば、電極支持部12R、12Lの各側を左右の手で把持しながら被験者の腹に押し当てて使用することができる。電極支持部12R、12Lは本体部10に対して可動状態で設けられていることから、本装置1は被験者の腹周りにぴったりフィットする。   FIG. 1 shows an external perspective view of a measuring apparatus having a positioning guide according to an embodiment of the present invention. The device 1 has a main body 10 that is slightly curved so as to conform to the shape of the abdomen of the subject, and a left and right side of the main body 10 so as to be able to bend somewhat with respect to the main body 10. The electrode support portions 12R and 12L are provided in a movable state. As shown in the figure, the device 1 may be of a handy type. For example, the device 1 can be used by pressing each side of the electrode support portions 12R, 12L with the left and right hands against the abdomen of the subject. . Since the electrode support parts 12R and 12L are provided in a movable state with respect to the main body part 10, the present apparatus 1 fits snugly around the abdomen of the subject.

本体部10の腹側面に、液晶表示部14と各種スイッチ16が設けてある。これらの部分は、測定中、被験者の腹側に配置される。測定中、被験者は、本体部10の表示を見ることはできないが、測定後に、腹から引き離すことによってそれを見ることができる。測定中も液晶表示部を見たり、各種スイッチを操作することができるよう、図2に示すように、液晶表示部14Aや各種スイッチ16Aを腹側面の対向側に設けても良い。図1の構成は、被験者自身が測定を行うのに適し、図2の構成は、横たわった状態の看者21等を測定するのに適する。特に、図2の構成によれば、本体部10A(の腹側)にも中央電極30Cを設けることができ、また、把持部18R、18Lを電極支持部12の腹側面の対向側に設けることができる。   A liquid crystal display unit 14 and various switches 16 are provided on the ventral side surface of the main body unit 10. These parts are placed on the ventral side of the subject during the measurement. During the measurement, the test subject cannot see the display of the main body unit 10, but can see it by pulling away from the belly after the measurement. As shown in FIG. 2, a liquid crystal display unit 14A and various switches 16A may be provided on the opposite side of the ventral side so that the liquid crystal display unit can be viewed and various switches can be operated even during measurement. The configuration of FIG. 1 is suitable for the subject himself / herself to perform measurement, and the configuration of FIG. 2 is suitable for measuring the observer 21 and the like in a lying state. In particular, according to the configuration of FIG. 2, the central electrode 30 </ b> C can be provided also on the main body 10 </ b> A (the ventral side thereof), and the gripping portions 18 </ b> R and 18 </ b> L are provided on the side opposite to the ventral side surface of the electrode support portion 12. Can do.

図1の実施形態に戻って、電極支持部12は、中心に穴を設けた支持枠20R、20Lと、これら支持枠20R、20Lの穴22R、22Lに左右にかけ渡された2本の並列スライド棒24R、24Lと、これらのスライド棒24R、24Lに沿ってスライド可能なスライド支持体26R、26Lから成る。スライド支持体26R、26Lの上面には、被験者の腹に配置される各種電極30R、32R、30L、32Lが設けてある。   Returning to the embodiment of FIG. 1, the electrode support 12 includes a support frame 20R, 20L provided with a hole in the center, and two parallel slides spanned to the left and right through the holes 22R, 22L of the support frames 20R, 20L. It comprises rods 24R, 24L and slide supports 26R, 26L that are slidable along the slide rods 24R, 24L. Various electrodes 30R, 32R, 30L, and 32L arranged on the subject's stomach are provided on the upper surfaces of the slide supports 26R and 26L.

電極30、32の数や位置は、使用態様に応じて決定される。図1の例では、電圧計測電極30R、30Lが上段に、電流印加電極32R、32Lが下段に、それぞれ1段ずつ設けてある。上記の構成から明らかなように、スライド支持体26上の電極30、32は、スライド支持体26R、26Lを装置の左右各側に図示矢印ア方向にスライドさせることによって、被験者の体の大きさに応じて様々な幅に設定され得る。この点は、図2に示した実施形態においても同様である。電極を可動とするため、図2の例では、把持部18R、18Lの先端が、各穴19R、19R’、19L、19L’を通じて電極30Rや30Lが載置されたスライド支持体(図示されていない)に連結されている。被験者等は、これら把持部18R、18Lを、各穴19、19’の延長方向沿いに動かすことにより、それらの先端と連結されたスライド支持体やその上に設けた電極30R、30Lを被験者の体の大きさに応じて適当な位置にスライドさせることができる。   The number and position of the electrodes 30 and 32 are determined according to the usage mode. In the example of FIG. 1, the voltage measurement electrodes 30R and 30L are provided in the upper stage, and the current application electrodes 32R and 32L are provided in the lower stage, respectively. As is apparent from the above configuration, the electrodes 30, 32 on the slide support 26 are sized by sliding the slide supports 26R, 26L to the left and right sides of the apparatus in the direction of the arrow A shown in the figure. Depending on the, it can be set to various widths. This also applies to the embodiment shown in FIG. In order to make the electrode movable, in the example of FIG. 2, the tip of the gripping portions 18R, 18L is a slide support (not shown) on which the electrodes 30R, 30L are placed through the holes 19R, 19R ′, 19L, 19L ′. Not connected). The subject or the like moves the gripping portions 18R and 18L along the extending direction of the holes 19 and 19 ′, so that the slide support connected to the tip thereof and the electrodes 30R and 30L provided on the slide support are connected to the subject. It can be slid to an appropriate position according to the size of the body.

電圧計測電極30や電流印加電極32は、SUS材及び樹脂材表面を金属めっき処理等して実現されていてもよい。このタイプの電極は、金属電極表面に、保水性高分子膜をコ−ティングすることで、測定前に水分をふきつけるか、水にぬらして使用する。水にぬらすことにより、皮膚との電気的接触の安定性を確保することができる。また、特に図示しないが、粘着性貼り付けタイプの電極を用いることもできる。これは交換可能な粘着パッドを各電極のベ−ス電極面に貼り付けて皮膚との接触安定性を確保するタイプのものである。このタイプは、例えば、低周波治療器や心電図電極等でよく用いられており、測定後に取り外して廃棄するようなディスポ形態と、パッド表面が汚れて密着性が低下したり水分が蒸発した場合にのみ廃棄交換し、廃棄するまでの間はカバ−シ−ト当で保管する形態がある。   The voltage measurement electrode 30 and the current application electrode 32 may be realized by performing metal plating on the surface of the SUS material and the resin material. This type of electrode is used by coating a water-retaining polymer film on the surface of a metal electrode to wipe off moisture before measurement or wet it with water. By soaking in water, the stability of the electrical contact with the skin can be ensured. Further, although not particularly shown, it is possible to use an adhesive-attached electrode. This is a type in which a replaceable adhesive pad is attached to the base electrode surface of each electrode to ensure contact stability with the skin. This type is often used, for example, in low-frequency treatment devices and electrocardiogram electrodes, etc., when it is removed and discarded after measurement, and when the pad surface becomes dirty and adhesion decreases or moisture evaporates There is a form that only stores and replaces until it is discarded.

本装置1を用いることにより、電極部を利用して求めた腹部電極配置測定区間のインピーダンス情報と被験者が入力等した身体特定化情報とから、被験者の内臓脂肪組織や皮下脂肪組織層の量を測定できる。特に、電極部を配置する電極配置測定区間は、被測定者の身体サイズによって異なるため、より正確な測定を行うには、相対的な測定位置への誘導手段を設けるのが好ましい。尚、インピーダンス情報は、身長情報との相関が期待できることから、身長情報(体重、性別、年齢等も補正情報としては対象とする測定集団によって有効な変数と成りうる)で補正することができ、シンプルな装置構造設計の観点からは、この方法を利用して、電極配置を固定した形態が望ましい。しかしながら、このような補正には限界がある。故に、個々人の骨格サイズ毎で決まる位置に電極を配置して計測されるインピーダンス情報を用いることによって、身体特定化情報でカバ−しきれない個々人のサイズズレによる誤差を改善することが所望される。   By using this device 1, the amount of the visceral adipose tissue or subcutaneous fat tissue layer of the subject is determined from the impedance information of the abdominal electrode arrangement measurement section obtained using the electrode portion and the body specifying information input by the subject. It can be measured. In particular, since the electrode arrangement measurement section in which the electrode unit is arranged varies depending on the body size of the measurement subject, it is preferable to provide a means for guiding to a relative measurement position in order to perform more accurate measurement. Since impedance information can be expected to correlate with height information, it can be corrected with height information (weight, sex, age, etc. can also be effective variables depending on the target measurement group as correction information), From the viewpoint of simple device structure design, a form in which the electrode arrangement is fixed using this method is desirable. However, there is a limit to such correction. Therefore, it is desirable to improve the error due to the size deviation of the individual that cannot be covered by the body specifying information by using the impedance information measured by arranging the electrode at a position determined for each individual skeleton size. .

電極の位置決め精度を上げるため、位置決めガイド部34R、34Lを設ける。位置決めガイド部34R、34Lは、例えば、スライド支持体26R、26Lの一部を下方に延長することによって形成される。図3に、位置決めガイド部34R、34Lの働きを説明するための概念図を示す。実際の使用にあたり、本装置1は、被験者21の臍A周囲付近に配置される。このとき、ガイド部34R、34Lは、スライド支持体26R、26Lを横方向(腹周方向)にスライドさせることによって、更にいえば、被験者21の皮膚表面より、軟組織下の骨組織のエッジ部を内側から押さえつけるようにスライドさせることによって、例えば、被験者の腸骨38の骨盤稜部(上前腸骨棘40R、40L)をそれらの内側から挟み込むようにして、被験者21の一部部位、例えば、上前腸骨棘40R、40Lと衝突した状態で配置される。このとき、電極30R、32R、30L、32Lは、被験者21の腹部付近の所定位置、例えば、腸骨稜上縁部42R、42L付近に配置される。尚、体幹長手方向の臍A位置に対しては、突起を設けている突起部を除いた電極ハウジング底面で腸骨稜上縁部42R、42Lに接触するように電極ハウジング部を配置することで体幹長手方向の位置決めをすることもできる。   Positioning guide portions 34R and 34L are provided to increase the positioning accuracy of the electrodes. The positioning guide portions 34R and 34L are formed, for example, by extending a part of the slide supports 26R and 26L downward. FIG. 3 is a conceptual diagram for explaining the function of the positioning guide portions 34R and 34L. In actual use, the present device 1 is arranged around the umbilicus A of the subject 21. At this time, the guide portions 34R and 34L slide the slide supports 26R and 26L in the lateral direction (abdominal circumferential direction), and more specifically, the edge portion of the bone tissue under the soft tissue from the skin surface of the subject 21. By sliding so as to press from the inside, for example, the pelvic ridge portion (upper anterior iliac spine 40R, 40L) of the subject's iliac 38 is sandwiched from the inside thereof, and a part of the subject 21, for example, It is arranged in a state of colliding with the superior anterior iliac spines 40R, 40L. At this time, the electrodes 30R, 32R, 30L, and 32L are disposed at predetermined positions near the abdomen of the subject 21, for example, near the iliac crest upper edges 42R and 42L. For the position of the umbilicus A in the longitudinal direction of the trunk, the electrode housing portion should be arranged so as to contact the iliac crest upper edges 42R and 42L on the bottom surface of the electrode housing excluding the protrusion provided with the protrusion. The positioning in the longitudinal direction of the trunk can also be performed.

図4に、電極配置の具体例を示す。この例では、一対の電流印加電極32R、32Lに加えて、第一の電圧計測電極30R、30Lの対と第二の電圧計測電極30R’、30L’の対が設けてある。ここで、第一の電圧計測電極30R、30Lの対は、皮下脂肪組織層を測定するためのもの、第二の電圧計測電極30R’、30L’の対は、内臓脂肪組織を測定するためのものである。   FIG. 4 shows a specific example of electrode arrangement. In this example, in addition to the pair of current application electrodes 32R and 32L, a pair of first voltage measurement electrodes 30R and 30L and a pair of second voltage measurement electrodes 30R 'and 30L' are provided. Here, the pair of the first voltage measurement electrodes 30R and 30L is for measuring the subcutaneous fat tissue layer, and the pair of the second voltage measurement electrodes 30R ′ and 30L ′ is for measuring the visceral fat tissue. Is.

よく知られているように、内臓脂肪組織や皮下脂肪組織層は、骨格筋組織層等に比して導電性が非常に悪く、組織構成及び組織分布を考慮した電極配置を取らないかぎり、骨格筋組織層支配の通電ルートになってしまう。そこで、内臓器組織および内臓脂肪組織の複合組織層においても測定に必要な感度を確保し、体幹部に蓄積される脂肪組織、特に、内臓器組織周辺に蓄積する内臓脂肪組織を測定するため、骨格筋組織層より内側の内臓器組織及び内臓脂肪組織の複合組織層における電流印加電極32R、32Lからの電流通電量を増やし、測定対象組織への計測感度を確保する必要がある。更に言えば、骨格筋組織層への電流通電量を抑制するためには、皮下脂肪組織層が薄い部位、または、骨格筋組織層の筋腹部が無いまたは薄い部位から、電流印加電極32R、32Lによって電流を印加し、同時に、皮下脂肪組織層が薄い部位、または、骨格筋組織層の筋腹部が無いまたは薄い部位において電位差を計測する必要がある。この目的を達成するため、電流印加電極32R、32Lの対と、特に、第二の電圧計測電極30R’、30L’の対を配置する位置が重要となる。例えば、電流印加電極32R、32Lから電流を印加する部位は、皮下脂肪組織層が最も薄く沈着する部位、または、導電性の良い骨格筋組織層の筋腹部が無いまたは薄い筋結合領域である、例えば、腱部(腱画、腱膜等)36、更に具体的に言えば、臍Aと腸骨稜上縁部42R、42L間の区間、腹直筋と外腹斜筋間の結合腱部(腱膜部)であり、第二の電圧計測電極30R’、30L’の対を設ける位置は、電位分布の乱れの少ない、皮下脂肪組織層が薄い部位、または、骨格筋組織層の筋腹部が無いまたは薄い部位である。位置決めガイド部を適当な位置に設けることにより、容易に、これらの電極対を上述したような所定位置に配置することができる。   As is well known, visceral adipose tissue and subcutaneous adipose tissue layers have very poor conductivity compared to skeletal muscle tissue layers, etc. It becomes the energization route of the muscle tissue layer control. Therefore, in order to ensure the sensitivity necessary for measurement even in the composite tissue layer of internal organ tissue and visceral adipose tissue, to measure adipose tissue accumulated in the trunk, particularly visceral adipose tissue accumulated around the internal organ tissue, It is necessary to increase the amount of current applied from the current application electrodes 32R and 32L in the composite tissue layer of internal organ tissue and visceral fat tissue inside the skeletal muscle tissue layer to ensure measurement sensitivity to the measurement target tissue. Furthermore, in order to suppress the amount of current applied to the skeletal muscle tissue layer, the current application electrodes 32R and 32L are applied from a portion where the subcutaneous fat tissue layer is thin, or a portion where the muscle abdominal portion of the skeletal muscle tissue layer is absent or thin. It is necessary to measure the potential difference at a site where the subcutaneous fat tissue layer is thin, or at the same time, where there is no muscle abdominal part of the skeletal muscle tissue layer or thin. In order to achieve this object, the position where the pair of current application electrodes 32R and 32L and particularly the pair of second voltage measurement electrodes 30R 'and 30L' are arranged is important. For example, the portion to which current is applied from the current application electrodes 32R and 32L is a portion where the subcutaneous fat tissue layer is deposited most thinly, or a region where the muscle abdomen of the skeletal muscle tissue layer having good conductivity is absent or thin. For example, a tendon part (tendon drawing, aponeurosis, etc.) 36, more specifically, a section between the umbilicus A and the iliac crest upper edges 42R and 42L, a joint tendon part between the rectus abdominis muscle and the external oblique muscle The position where the second voltage measurement electrodes 30R ′ and 30L ′ are provided is a site where the potential distribution is less disturbed and the subcutaneous fat tissue layer is thin, or the muscle abdominal part of the skeletal muscle tissue layer There is no or thin part. By providing the positioning guide portion at an appropriate position, these electrode pairs can be easily arranged at the predetermined positions as described above.

また、皮下層に蓄積する皮下脂肪組織層情報を前記内臓脂肪組織とともに測定するためには、前記電流印加電極32R、32L及び第二の電圧計測電極30R’、30L’の電極配置とともに第一の電圧計測電極30R、30Lの対を配置する位置が重要となる。電流印加電極直下の皮下脂肪組織層の計測は、R、L各々において、第一の電圧計測電極を電流印加電極に近接して配置し、第一の電圧計測電極と第二の電圧計測電極間の電位差を測定することで、電流印加電極直下のひろがり抵抗領域の情報として得ることができる。   In order to measure subcutaneous fat tissue layer information accumulated in the subcutaneous layer together with the visceral adipose tissue, the first electrode together with the electrode arrangement of the current application electrodes 32R and 32L and the second voltage measurement electrodes 30R ′ and 30L ′ is used. The position where the pair of voltage measuring electrodes 30R and 30L is arranged is important. In the measurement of the subcutaneous fat tissue layer directly under the current application electrode, in each of R and L, the first voltage measurement electrode is disposed close to the current application electrode, and between the first voltage measurement electrode and the second voltage measurement electrode. Can be obtained as information on the spread resistance region directly under the current application electrode.

図5、図6に、本発明の他の実施形態による測定装置の外観とその使用法をそれぞれ示す。この測定装置1’では、従来装置を示す図7、図8と同様に、本体部50とグリップ電極部130、140が互いに分離した状態で設けてある。尚、これら図5、図6において、図7、図8と同様の部材については、同じ番号を付している。   5 and 6 show the appearance of a measuring apparatus according to another embodiment of the present invention and how to use it. In this measuring apparatus 1 ′, the main body 50 and the grip electrode parts 130 and 140 are provided in a state of being separated from each other, as in FIGS. 7 and 8 showing the conventional apparatus. 5 and 6, the same members as those in FIGS. 7 and 8 are given the same reference numerals.
