***力測定装置  Lip force measuring device
技術分野  Technical field
[0001] 本発明は***力を測定するための***力測定装置に関する。  The present invention relates to a lip force measuring device for measuring lip force.
背景技術  Background art
[0002] 口の中の食べ物をこぼさず、上手に嚙むためには、***の閉鎖が機能的に行なわ れる必要がある。また、食べ物を飲み込む時には***が閉鎖されていないと、食べ 物をうまく飲み込むことができな 、。  [0002] In order not to spill food in the mouth and to drink well, lip closure needs to be performed functionally. Also, when you swallow food, if your lips are not closed, you can not swallow food well.
[0003] さらに、最近では口の開いた子供等が増えており、子供等の口呼吸が問題にもなつ ている。また、***力が弱いといわゆる出歯になるともいわれている。このように、口 唇力は食べ物を咀嚼するときや言葉を発音するときに重要な役割を担っている。  Furthermore, recently, children with open mouths and the like are increasing, and mouth breathing of children and the like is also becoming a problem. In addition, it is said that so-called teeth are created when the lip force is weak. Thus, lip power plays an important role in chewing food and pronouncing words.
[0004] さらに近年、***力と口腔器官 (例えば、顎、頭蓋骨、歯列、舌)の成長発達との間 に密接な関係があると報告されている。しかし、***力は、口裂周囲の筋肉とともに 収縮する上下の***に存在する口輪筋の様々な複雑な運動によって発生することか ら、科学的に裏付けされた***力の評価法が確立していな力つた。  [0004] More recently, it has been reported that there is a close relationship between lip force and the growth and development of oral organs (eg, jaw, skull, dentition, tongue). However, since the lip force is generated by various complex movements of the orbicularis oris muscle present in the upper and lower lip, which contracts with the muscles surrounding the cleft lip, a scientifically backed evaluation method of lip force is established. It was a powerful force.
発明の開示  Disclosure of the invention
発明が解決しょうとする課題  Problem that invention tries to solve
[0005] し力しながら、従来は***力を研究の対象にした事例がほとんど無力つた。例えば 、現状の測定機器は、***力を上下方向にしか測定することができず、***力に 伴う複雑な特徴的動きを考慮していない。よって、現状の測定機器は、複数の方向 での***力を直接測定することができない。今後、***力を咀嚼や発音との関係で 評価'研究して 、く為に、***力に係る複雑且つ機能的な動きを正確に測定できる 装置が望まれている。 [0005] In the past, most of the cases where research on lip force was the subject were almost helpless. For example, current measuring devices can only measure lip force in the vertical direction, and do not take into account the complex characteristic movements associated with lip force. Therefore, current measuring devices can not directly measure lip force in multiple directions. In the future, in order to evaluate and research lip strength in relation to pressure sore and pronunciation, a device capable of accurately measuring complex and functional movement relating to lip power is desired.
[0006] したがって、本発明は上述に鑑みてなされたものであり、簡単な構成で、***力を 正確かつ精細に測定できる***力測定装置を提供することを目的とする。  Therefore, the present invention has been made in view of the above, and it is an object of the present invention to provide a lip force measuring device capable of accurately and precisely measuring lip force with a simple configuration.

[0040] 〔測定方法〕  [Measuring method]
次に上記***力測定装置 100を用いた***力の測定方法について説明する。  Next, a method of measuring lip force using the lip force measuring device 100 will be described.
[0041] 図 8は、本発明の***力測定装置を用いた測定方法の一実施例を説明するため の概略図である。  [0041] FIG. 8 is a schematic view for explaining an embodiment of a measuring method using the lip force measuring device of the present invention.
[0042] まず、第 1ポート P1と、第 2ポート P2と、第 3ポート P3とを接続するためにバルブ 12 6のレバー 126aを調節する。これにより、測定用チューブ 121、接続用チューブ 127 の内圧が大気圧にセットされる。このとき、検出部 113或いは処理部 114は、圧力セ ンサ 222の出力電気信号を、大気圧との関係で、オフセット成分として記憶する。  First, the lever 126a of the valve 126 is adjusted to connect the first port P1, the second port P2 and the third port P3. As a result, the internal pressure of the measuring tube 121 and the connecting tube 127 is set to the atmospheric pressure. At this time, the detection unit 113 or the processing unit 114 stores the output electric signal of the pressure sensor 222 as an offset component in relation to the atmospheric pressure.
[0043] 次に、レバー 126aを操作して、第 1端と第 2端とが接続され、第 3端が閉鎖されるよ うにする。  Next, the lever 126a is operated so that the first end and the second end are connected and the third end is closed.
[0044] 次に、測定用チューブ 121のチューブクランプ 123の表面方向への延出部分を被 験者 101に垤えてもらい、被験者 101に測定用チューブ 121に対して***力をかけ てもらう。その***力に応じて、図 8に示すように、加えられる***力に対応する箇所 の測定用チューブ 121が押圧され、変形する。測定用チューブ 121が変形すること により、測定チューブ 121及びそれに接続された接続チューブ 127の内圧が上昇す る。このとき、測定チューブ 121及びそれに接続された接続チューブ 127の内圧は、 ***力に応じて、変化する。よって、測定チューブ 121及びそれに接続された接続 チューブ 127の内圧を圧力センサ 222により検出することにより、***力を測定する ことが可能となる。 Next, the test subject 101 holds the extension of the measurement tube 121 in the surface direction of the tube clamp 123, and the test subject 101 applies a lip force to the measurement tube 121. Get According to the lip force, as shown in FIG. 8, the measuring tube 121 at the portion corresponding to the applied lip force is pressed and deformed. As the measuring tube 121 is deformed, the internal pressure of the measuring tube 121 and the connection tube 127 connected thereto is increased. At this time, the internal pressure of the measurement tube 121 and the connection tube 127 connected thereto changes in accordance with the lip force. Therefore, it is possible to measure the lip force by detecting the internal pressure of the measurement tube 121 and the connection tube 127 connected thereto by the pressure sensor 222.
[0045] この実施例では、チューブホルダ 122の周囲に 8本の測定用チューブ 121を配置し てある。測定用チューブの各々力 独立に圧力を検出することができるので、***力 が働 、て 、る方向及び大きさも検出することができる。  In this embodiment, eight measurement tubes 121 are arranged around the tube holder 122. Since the pressure can be detected independently for each force of the measuring tube, it is also possible to detect the direction and the size of the lip force.

[0048] このように、本発明の***力測定装置 100の一実施例は、***力をその大きさだけ でなぐその方向を検出することが可能となる。 Thus, one embodiment of the lip force measuring device 100 of the present invention can detect the direction in which the lip force is reduced by the magnitude only.
[0049] 〔効果〕 [Effect]
本実施例の***力測定装置 100を用いることより、簡単な構成で、***力を正確か つ精細に測定することが可能になる。これにより、複数方向の***力に関連する様々 な動きを評価'研究することが可能になる。また、***力が口腔器官 (例えば、顎、頭 蓋骨、歯列、舌)の成長発達とどのような関係がある力を知ることができる。さらに、口 の働きが悪くなつた脳障害者や年長者 (食べることや話すことに障害のある人)のリノ、 ピリを行う際にこの***力測定装置を使用し、これにより、***力（口すぼめ力）とリハ ピリの回復度合いとの関係を調べることができ、リハビリの回復度合いの評価に使え る。また、空気圧等の圧力が、***力測定の被験者の***に対するインタフェースで あるため、被験者に不快感の少な 、測定が可能となる。 By using the lip force measuring device 100 of this embodiment, it is possible to measure the lip force accurately and precisely with a simple configuration. This makes it possible to 'assessing' and researching various movements related to lip forces in multiple directions. In addition, we can know how the lip force is related to the growth and development of the oral organs (eg, jaw, head, bone, teeth, tongue). In addition, when using this lip strength measuring device when performing reno or piri on a brain disorder or an elderly person (person with eating or talking problems) who has a bad mouth function, It can be used to examine the relationship between the power of recovery and the degree of rehabilitation recovery, and can be used to evaluate the degree of rehabilitation rehabilitation. In addition, pressure such as air pressure is the interface to the lip of the subject of lip force measurement This makes it possible to measure less discomfort for the subject.
