Description

荷重分布計測装置及び荷重分布計測システムLoad distribution measuring device and load distribution measuring system
　本発明は、被検者の荷重分布を可視化するための荷重分布計測装置及び荷重分布計測システムに関するものである。 The present invention relates to a load distribution measuring device and a load distribution measuring system for visualizing a load distribution of a subject.
　脳卒中などの脳神経系疾患を発症し、右片または左片が麻痺した患者に対しては、従来より、理学療法士等の指導／監視のもとで、運動機能回復訓練が行われてきた。一般的に、自立的な生活を営むためには、下肢機能の回復が不可欠であり、理学療法士等は、訓練時に患者の下肢機能の回復状態を適確に判断することが必要となってくる。このため、運動機能回復訓練に際しては、患者の足圧分布等の計測を行い、下肢機能の回復状態を定量的に評価することが望ましい。 For patients with cranial nervous system diseases such as stroke and paraplegia on the right or left side, motor function recovery training has been performed under the guidance / monitoring of physical therapists. In general, recovery of lower limb function is indispensable for living an independent life, and it is necessary for physical therapists to accurately determine the recovery status of the patient's lower limb function during training. come. For this reason, in exercise function recovery training, it is desirable to measure a patient's foot pressure distribution and quantitatively evaluate the recovery state of lower limb function.
　一方で、被検者の足圧分布を計測し可視化するシステムとして、従来より、感圧素子をマトリックス状に配列したセンサ部を備える足圧分布計測システムが用いられている。当該足圧分布計測システムによれば、被検者の両足をセンサ部に載置した状態の足圧分布を、リアルタイムで視認することができる。 On the other hand, as a system for measuring and visualizing the foot pressure distribution of a subject, a foot pressure distribution measuring system including a sensor unit in which pressure-sensitive elements are arranged in a matrix is conventionally used. According to the foot pressure distribution measurement system, the foot pressure distribution in a state where both feet of the subject are placed on the sensor unit can be viewed in real time.
　更に、当該システムを応用することにより、座った状態における被検者の座圧分布や、横臥した状態における被検者の体圧分布等をリアルタイムに表示させることも可能である。なお、以下、本明細書では、足圧分布や座圧分布、体圧分布等をまとめて、“荷重分布”と称するとともに、荷重分布を計測する装置を“荷重分布計測装置”と、荷重分布計測装置において荷重分布を計測し可視化するシステムを“荷重分布計測システム”と、それぞれ称することとする。 Furthermore, by applying the system, it is possible to display the sitting pressure distribution of the subject in a sitting state, the body pressure distribution of the subject in a lying state, and the like in real time. Hereinafter, in this specification, the foot pressure distribution, the seat pressure distribution, the body pressure distribution, and the like are collectively referred to as “load distribution”, and an apparatus for measuring the load distribution is referred to as “load distribution measuring apparatus” and load distribution. A system for measuring and visualizing the load distribution in the measuring device is referred to as a “load distribution measuring system”.

　しかしながら、上述のように、感圧素子を配列してなるセンサ部を有する荷重分布計測装置の場合、被検者の荷重分布を繰り返し計測することに伴う感圧素子の劣化等の経時変化を考慮しておく必要がある。劣化により、被検者の荷重分布に計測誤差が生じると、被検者の回復状態を適確に判断することができなくなってしまうからである。 However, as described above, in the case of a load distribution measuring apparatus having a sensor unit in which pressure sensitive elements are arranged, taking into account changes over time such as deterioration of the pressure sensitive elements due to repeated measurement of the load distribution of the subject. It is necessary to keep it. This is because if a measurement error occurs in the load distribution of the subject due to the deterioration, the recovery state of the subject cannot be accurately determined.
　一方で、感圧素子の劣化等の経時変化が進むたびに、荷重分布計測装置全体の交換が必要であるとすると、交換コストが増大してしまうといった問題もある。 On the other hand, if it is necessary to replace the entire load distribution measuring device each time a change over time such as deterioration of the pressure sensitive element proceeds, there is a problem that the replacement cost increases.
　このようなことから、感圧素子の劣化等の経時変化に対しては、センサ部のみを簡単に交換できる構成とすることで、被検者の荷重分布の計測誤差を、早期に、かつ、低コストで改善することができるものと期待される。 For this reason, with respect to changes over time such as deterioration of the pressure-sensitive element, it is possible to easily replace the sensor unit only, thereby measuring the load distribution measurement error of the subject at an early stage, and It is expected that it can be improved at low cost.
　本発明は、上記課題に鑑みてなされたものであり、荷重分布計測装置において、経時変化に伴う荷重分布の計測誤差を、早期に、かつ、低コストで改善できるようにすることを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to enable a load distribution measuring apparatus to improve load distribution measurement errors accompanying changes with time at an early stage and at a low cost. .
　上記の目的を達成するために、本発明に係る情報処理装置は以下のような構成を備える。即ち、

This is referred to as “calculation data”.

　＜３．荷重分布計測装置の構成＞
　次に、荷重分布計測装置１１０の詳細構成について説明する。図４は、荷重分布計測装置１１０の詳細構成を説明するための図である。 <3. Configuration of load distribution measuring device>
Next, a detailed configuration of the load distribution measuring apparatus 110 will be described. FIG. 4 is a diagram for explaining a detailed configuration of the load distribution measuring apparatus 110.
　図４の４ａは、開閉部１１２を開き、感圧素子が劣化したセンサ部を取り外した状態を示している。図４の４ａに示すように、基部１１１は、交換する新たなセンサ部１１５が載置される、平面形状の載置部４１２を備える。 4a in FIG. 4 shows a state in which the opening / closing part 112 is opened and the sensor part in which the pressure sensitive element has deteriorated is removed. As shown to 4a of FIG. 4, the base 111 is provided with the planar mounting part 412 in which the new sensor part 115 to replace | exchange is mounted.
　載置部４１２は、センサ部１１５の裏面の全部を支持するよう構成されており、周囲には、取り付けられたセンサ部１１５の側面の位置を規定するための側壁部４１３が設けられている。また、載置部４１２の先端側の側壁部４１３には、不図示の回動機構が設けられており、開閉部１１２は、当該回動機構を介して基部１１１の側壁部４１３に回動可能に取り付けられている。 The mounting unit 412 is configured to support the entire back surface of the sensor unit 115, and a side wall unit 413 for defining the position of the side surface of the attached sensor unit 115 is provided around the mounting unit 412. In addition, a rotation mechanism (not shown) is provided on the side wall portion 413 on the distal end side of the mounting portion 412, and the opening / closing portion 112 can rotate to the side wall portion 413 of the base 111 via the rotation mechanism. Is attached.
　開閉部１１２は、当該回動機構により閉位置まで回動することでセンサ部１１５の先端側の領域を基部１１１との間で把持し、載置部４１２上にセンサ部１１５を固定する。 The opening / closing part 112 grips the region on the distal end side of the sensor part 115 with the base part 111 by turning to the closed position by the turning mechanism, and fixes the sensor part 115 on the mounting part 412.
　開閉部１１２の端部には、フィルム１１４が接続されており、開閉部１１２が閉位置まで回動することで、載置部４１２に新たに載置されたセンサ部１１５は、フィルム１１４により覆われることとなる。 A film 114 is connected to the end of the opening / closing part 112, and the sensor part 115 newly placed on the placing part 412 is covered by the film 114 when the opening / closing part 112 rotates to the closed position. Will be.
　開閉部１１２の裏面（表示部１１３が取り付けられた面と反対側の面）には、端子４１１が配されており、開閉部１１２が閉位置まで回動することで、載置部４１２に載置されたセンサ部１１５の中央部に位置する端子４０１と接触し、開閉部１１２とセンサ部１１５とは、電気的に接続されることとなる。 A terminal 411 is arranged on the back surface of the opening / closing unit 112 (the surface opposite to the surface on which the display unit 113 is attached), and the opening / closing unit 112 is rotated to the closed position so that the mounting unit 412 is mounted. The opening / closing part 112 and the sensor part 115 are electrically connected by contacting the terminal 401 located at the center of the placed sensor part 115.
　これにより、センサ部１１５において計測された足圧分布算出用データを、開閉部１１２内に設けられた不図示の通信部において処理し、情報処理装置１２０に送信することが可能となる。 Thus, the foot pressure distribution calculation data measured by the sensor unit 115 can be processed by a communication unit (not shown) provided in the opening / closing unit 112 and transmitted to the information processing apparatus 120.
　図４の４ｂは、載置部４１２にセンサ部１１５を載置した様子を示している。図４の４ｂに示すように、センサ部１１５を、側壁部４１３の後端側に接触するように載置部４１２上に載置することで、センサ部１１５に配された端子４０１の位置と、閉位置まで回動した開閉部１１２の端子４１１の位置とが一致することとなる。 4b of FIG. 4 shows a state in which the sensor unit 115 is mounted on the mounting unit 412. As shown in 4b of FIG. 4, the sensor unit 115 is placed on the placement unit 412 so as to be in contact with the rear end side of the side wall portion 413, so that the position of the terminal 401 arranged on the sensor unit 115 Therefore, the position of the terminal 411 of the opening / closing part 112 rotated to the closed position coincides.
　図４の４ｃは、載置部４１２へのセンサ部１１５の載置が完了し、開閉部１１２を開位置から閉位置へと回動させている様子を示している。図４の４ｄは、開閉部１１２の閉位置への回動が完了した様子を示している。 4c of FIG. 4 shows a state where the mounting of the sensor unit 115 on the mounting unit 412 is completed and the opening / closing unit 112 is rotated from the open position to the closed position. 4d of FIG. 4 has shown the mode that the rotation to the closed position of the opening-and-closing part 112 was completed.
　図４の４ｄに示すように、開閉部１１２が閉位置まで回動することにより、
・センサ部１１５と開閉部１１２とが電気的に接続され、
・センサ部１１５の先端側の領域が基部１１１と開閉部１１２との間で把持されて固定され、
・センサ部１１５の表面が、フィルム１１４により覆われ、
・センサ部１１５の表示部１１３が、上方から視認できるようになる。 As shown in 4d of FIG. 4, when the opening / closing part 112 is rotated to the closed position,
The sensor unit 115 and the opening / closing unit 112 are electrically connected,
The region on the tip side of the sensor unit 115 is gripped and fixed between the base 111 and the opening / closing unit 112,
The surface of the sensor unit 115 is covered with the film 114,
The display unit 113 of the sensor unit 115 can be viewed from above.
　以上の説明から明らかなように、本実施形態に係る荷重分布計測装置１１０は、センサ部１１５が載置される基部１１１に対して回動可能に取り付けられた開閉部１１２を有し、開閉部１１２が閉位置まで回動した場合に、開閉部１１２と基部１１１との間で、センサ部１１５の端部を把持するとともに、センサ部１１５と電気的に接続させる構成とした。 As is clear from the above description, the load distribution measuring apparatus 110 according to the present embodiment has the opening / closing part 112 that is rotatably attached to the base part 111 on which the sensor part 115 is placed. When the 112 rotates to the closed position, the end of the sensor unit 115 is gripped between the opening / closing unit 112 and the base 111 and is electrically connected to the sensor unit 115.
　これにより、開閉部１１２を開閉動作させるだけで、センサ部１１５を容易に着脱することが可能となった。この結果、センサ部１１５の感圧素子の劣化等の経時変化が進んだ場合であっても、センサ部１１５のみを簡単に交換することができるようになり、経時変化に伴う荷重分布の計測誤差を、早期に、かつ、低コストで改善することが可能となった。 This makes it possible to easily attach and detach the sensor unit 115 simply by opening and closing the opening and closing unit 112. As a result, even when a change with time such as deterioration of the pressure sensitive element of the sensor unit 115 progresses, it becomes possible to easily replace only the sensor unit 115, and a load distribution measurement error accompanying the change with time Can be improved at an early stage and at a low cost.
　［第２の実施形態］
　上記第１の実施形態では、開閉部１１２を閉位置まで回動させた場合に、開閉部１１２の自重、及び、開閉部１１２を側壁部４１３に回動可能に取り付けるための回動機構の摩擦力により、開閉部１１２の閉位置を維持する構成としたが、本発明はこれに限定されない。例えば、開閉部１１２の閉位置を維持するためのストッパ部を更に設けるようにしてもよい。 [Second Embodiment]
In the first embodiment, when the opening / closing part 112 is turned to the closed position, the weight of the opening / closing part 112 and the friction of the turning mechanism for rotatably attaching the opening / closing part 112 to the side wall part 413 are provided. Although the closed position of the opening / closing part 112 is maintained by force, the present invention is not limited to this. For example, a stopper part for maintaining the closed position of the opening / closing part 112 may be further provided.
　図５は、本実施形態に係る荷重分布計測装置５１０の詳細構成を説明するための図であり、開閉部１１２の閉位置を維持するためのストッパ部５１１、５１２を備える荷重分布計測装置５１０を示す図である。なお、図５の５ａから５ｄのうち、上述の図４の４ａから４ｄと同じ構成については、同じ参照番号を付すこととし、ここでは説明は省略する。以下では、図４の４ａから４ｄに示す第１の実施形態に係る荷重分布計測装置１１０の詳細構成との相違点を中心に説明する。 FIG. 5 is a diagram for explaining a detailed configuration of the load distribution measuring apparatus 510 according to the present embodiment. The load distribution measuring apparatus 510 including stopper portions 511 and 512 for maintaining the closed position of the opening / closing section 112 is illustrated. FIG. Note that, among 5a to 5d in FIG. 5, the same components as those in 4a to 4d in FIG. 4 described above are denoted by the same reference numerals, and description thereof is omitted here. Below, it demonstrates centering on difference with the detailed structure of the load distribution measuring device 110 which concerns on 1st Embodiment shown to 4d from 4a of FIG.
　図５の５ａに示すように、基部１１１の側壁部４１３のうち、載置部４１２の先端側の側壁部４１３上には、ストッパ部５１１、５１２が取り付けられている。ストッパ部５１１、５１２は、開閉部１１２の回動動作の妨げとならない退避位置と、開閉部１１２の閉位置を維持するための保持位置との間を、矢印５２１方向に摺動するよう、側壁部４１３上に取り付けられている。 As shown in 5a of FIG. 5, the stopper parts 511 and 512 are attached on the side wall part 413 of the mounting part 412 among the side wall parts 413 of the base 111. The stopper portions 511 and 512 have sidewalls that slide in the direction of the arrow 521 between a retracted position that does not hinder the rotation of the opening and closing portion 112 and a holding position for maintaining the closed position of the opening and closing portion 112. It is mounted on the part 413.
　図５の５ａ～５ｃは、ストッパ部５１１、５１２が、開閉部１１２の回動に際してそれぞれ退避位置まで摺動した状態を示している。 5a to 5c in FIG. 5 show a state in which the stopper portions 511 and 512 are slid to the retracted position when the opening / closing portion 112 is rotated.
　一方、図５の５ｄは、ストッパ部５１１、５１２が、保持位置まで摺動した様子を示している。このように、ストッパ部５１１、５１２が開閉部１１２の上面を下方向に押圧した状態で保持位置に固定されることで、開閉部１１２と基部１１１との間で把持するセンサ部１１５に対する把持力が向上することとなる。この結果、被検者の両足が荷重分布計測装置１１０に載置された際に、センサ部１１５の位置がずれたり、センサ部１１５がゆがみ、端子４０１と端子４１１との間の接触不良が発生するといった事態を回避することが可能となる。 On the other hand, 5d in FIG. 5 shows a state in which the stopper portions 511 and 512 have slid to the holding position. As described above, the stoppers 511 and 512 are fixed to the holding position while pressing the upper surface of the opening / closing part 112 downward, so that the gripping force on the sensor part 115 gripped between the opening / closing part 112 and the base 111 is obtained. Will be improved. As a result, when both feet of the subject are placed on the load distribution measuring device 110, the position of the sensor unit 115 is displaced, the sensor unit 115 is distorted, and a poor contact between the terminal 401 and the terminal 411 occurs. It is possible to avoid such a situation.
　［第３の実施形態］
　上記第１及び第２の実施形態では、基部１１１に載置部４１２を設け、センサ部１１５の裏面の全部を支持するとともに、載置部４１２に側壁部４１３を設け、載置部４１２に載置されたセンサ部１１５の位置を規定するように構成したが、本発明はこれに限定されない。 [Third Embodiment]
In the first and second embodiments, the mounting portion 412 is provided on the base 111 to support the entire back surface of the sensor unit 115, and the side wall portion 413 is provided on the mounting portion 412, and is mounted on the mounting portion 412. The position of the placed sensor unit 115 is defined, but the present invention is not limited to this.
　例えば、基部に設けられた載置部を、センサ部１１５の裏面の一部のみを支持するよう構成するとともに、載置部の側壁部をなくし、センサ部１１５の交換作業をより行いやすくするように構成してもよい。 For example, the mounting unit provided in the base is configured to support only a part of the back surface of the sensor unit 115 and the side wall of the mounting unit is eliminated, so that the sensor unit 115 can be replaced more easily. You may comprise.
　図６は、本発明の第３の実施形態に係る荷重分布計測装置６１０の詳細構成を説明するための図である。 FIG. 6 is a diagram for explaining a detailed configuration of a load distribution measuring apparatus 610 according to the third embodiment of the present invention.
　図６の６ａは、開閉部６１２を開き、感圧素子が劣化したセンサ部を取り外した状態を示している。図６の６ａに示すように、基部６１１は、交換する新たなセンサ部１１５の先端側の領域が載置される、平面形状の載置部６２１を備える。 6a in FIG. 6 shows a state in which the opening / closing part 612 is opened and the sensor part having the deteriorated pressure sensitive element is removed. As shown to 6a of FIG. 6, the base 611 is equipped with the planar mounting part 621 in which the area | region of the front end side of the new sensor part 115 to replace | exchange is mounted.
　開閉部６１２は、基部６１１に設けられた回動機構６２２を介して、基部６１１に対して回動可能に取り付けられている。開閉部６１２は、当該回動機構６２２により閉位置まで回動することで、センサ部１１５の先端側の領域を基部１１１との間で把持し、載置部６２１上にセンサ部１１５を固定する。 The opening / closing part 612 is rotatably attached to the base 611 via a turning mechanism 622 provided in the base 611. The opening / closing unit 612 is rotated to the closed position by the rotation mechanism 622, thereby gripping the region on the distal end side of the sensor unit 115 with the base unit 111 and fixing the sensor unit 115 on the mounting unit 621. .
　また、開閉部６１２の表面には、表示部６１３が取り付けられており、裏面（表示部６１３が取り付けられた面と反対側の面）には、不図示の端子が配されており、開閉部６１２が閉位置まで回動することで、載置部６２１に載置されたセンサ部１１５の中央部に位置する端子４０１と接触し、開閉部１１２とセンサ部１１５とは電気的に接続されることとなる。 A display unit 613 is attached to the front surface of the opening / closing unit 612, and terminals (not shown) are arranged on the back surface (the surface opposite to the surface to which the display unit 613 is attached). By rotating 612 to the closed position, it contacts the terminal 401 located at the center of the sensor unit 115 mounted on the mounting unit 621, and the opening / closing unit 112 and the sensor unit 115 are electrically connected. It will be.
　これにより、センサ部１１５において計測された足圧分布算出用データを、開閉部６１２内に設けられた不図示の通信部において処理し、情報処理装置１２０に送信することが可能となる。 Thus, the foot pressure distribution calculation data measured by the sensor unit 115 can be processed by a communication unit (not shown) provided in the opening / closing unit 612 and transmitted to the information processing apparatus 120.
　図６の６ｂは、載置部６２１にセンサ部１１５の先端部を載置した様子を示している。図６の６ｂに示すように、センサ部１１５を、先端壁６２３に接触するように載置部６２１に載置することで、センサ部１１５に配された端子４０１は、閉位置まで回動した開閉部６１２の端子（不図示）によって電気的に接続されることとなる。 6b of FIG. 6 shows a state where the tip of the sensor unit 115 is placed on the placement unit 621.

It is desirable to place it so as to cover the entire area (area other than the area).
　図６の６ｄは、開閉部１１２の閉位置までの回動が完了した様子を示している。図６の６ｄに示すように、開閉部６１２が閉位置まで回動することにより、
・センサ部１１５と開閉部６１２とが電気的に接続され、
・センサ部１１５及びフィルム６３１の先端側の領域が基部６１１と開閉部６１２との間で把持されて固定され、
・センサ部１１５の表面が、フィルム６３１により覆われ、
・センサ部１１５の表示部６１３が、上方から視認できるようになる。 6d of FIG. 6 has shown the mode that rotation to the closed position of the opening-and-closing part 112 was completed. As shown in 6d of FIG. 6, the opening / closing part 612 rotates to the closed position,
The sensor unit 115 and the opening / closing unit 612 are electrically connected,

When the opening / closing part 612 is rotated to the closed position, the tip part of the sensor part 115 is gripped between the base part 611 and electrically connected to the sensor part 115.
　これにより、開閉部６１２を開閉動作させるだけで、センサ部１１５を容易に着脱することが可能となった。この結果、センサ部１１５の感圧素子の劣化等の経時変化が進んだ場合であっても、センサ部１１５のみを簡単に交換することができるようになり、経時変化に伴う荷重分布の計測誤差を、早期に、かつ、低コストで改善することが可能となった。 This makes it possible to easily attach and detach the sensor unit 115 simply by opening and closing the opening and closing unit 612. As a result, even when the change over time such as the deterioration of the pressure sensitive element of the sensor unit 115 progresses, it becomes possible to easily replace only the sensor unit 115, and the load distribution measurement error accompanying the change over time. Can be improved at an early stage and at a low cost.
