Description

本発明は、骨盤底筋の筋力を表示する筋力表示装置に関する。 The present invention relates to a muscle strength display device that displays the muscle strength of pelvic floor muscles.

骨盤底筋は、骨盤の底部に位置するハンモック状の筋肉であり、内臓を支えたり、排泄をコントロールする役目を担う。骨盤底筋の筋力を高めることにより、内臓下垂を防止したり、尿失禁等を防止できる。尿失禁の経験がある成人女性は約4割であり、重症の場合には生活の質を大きく損なうことになる。
骨盤底筋の筋力を高めるためのトレーニングとして、例えば随意的に骨盤底筋を収縮させる「骨盤底筋体操」(「ケーゲル体操」)が知られている。
Pelvic floor muscles are hammock-shaped muscles located at the bottom of the pelvis, and are responsible for supporting internal organs and controlling excretion. By increasing the strength of the pelvic floor muscles, it is possible to prevent visceral drooping and urinary incontinence. Approximately 40% of adult women experience urinary incontinence, and in severe cases, it can significantly impair quality of life.
As a training for increasing the strength of the pelvic floor muscles, for example, "pelvic floor muscle exercises"("Kegelexercises") in which the pelvic floor muscles are voluntarily contracted are known.

一方、骨盤底筋の筋力を高めるための各種装置も提案されている。
例えば特許文献1に記載された運動装置は、弾性を有した帯板を長手方向の中間で略V字形状に折り返すことにより作製されている。特許文献1の運動装置は、折り返し部を境に第1の部分と第2の部分とを備えており、第1の部分と第2の部分との間隔は折り返し部から離れるにつれて漸次拡げられている。
特許文献1の運動装置は、折り返し部を先頭にして第1の部分と第2の部分とを膣内に挿入することによって使用される。この運動装置は、折り返し部が弾性を有しているため、第1の部分と第2の部分の間隔を狭めるためには、折り返し部の弾性力よりも大きい外力が必要になる。
従って、第1の部分、及び第2の部分を膣内に挿入した状態で骨盤底筋を収縮させると、折り返し部の弾性力(抗力)が骨盤底筋に作用するので筋力が高められる。
On the other hand, various devices have also been proposed to increase the strength of the pelvic floor muscles.
For example, the exercise device described in Patent Document 1 is manufactured by folding an elastic band plate into a substantially V-shape at the middle in the longitudinal direction. The exercise device of Patent Document 1 includes a first part and a second part with a folded part as a boundary, and the distance between the first part and the second part gradually increases as the distance from the folded part increases. There is.
The exercise device of Patent Document 1 is used by inserting the first part and the second part into the vagina with the folded part at the beginning. Since the folded portion of this exercise device has elasticity, an external force greater than the elastic force of the folded portion is required to narrow the distance between the first portion and the second portion.
Therefore, when the pelvic floor muscles are contracted with the first portion and the second portion inserted into the vagina, the elastic force (resistance) of the folded portion acts on the pelvic floor muscles, thereby increasing the muscle strength.

特許文献2には、感圧センサを備えた丸棒形状の測定部と、接続部(通信コード)を介して測定部と電気的に接続された処理表示部と、を備えた訓練装置が開示されている。
特許文献2の訓練装置によって骨盤底筋を訓練するためには、測定部を肛門から直腸内に挿入し、肛門を引き締める要領で骨盤底筋を収縮させる動作を行う。骨盤底筋を収縮させると測定部からの抗力が骨盤底筋に作用するので筋力が高められる。
処理表示部は、訓練時において、感圧センサから得られた信号に基づいて骨盤底筋の動き成分を表す情報を取り出して表示する。従って、特許文献2の訓練装置では、骨盤底筋の動きに基づいて訓練の客観的評価が行える。
Patent Document 2 discloses a training device that includes a round bar-shaped measurement section equipped with a pressure-sensitive sensor and a processing display section electrically connected to the measurement section via a connection section (communication cord). has been done.
In order to train the pelvic floor muscles using the training device of Patent Document 2, the measuring section is inserted into the rectum through the anus, and an action is performed to contract the pelvic floor muscles in a manner similar to tightening the anus. When the pelvic floor muscles are contracted, the resistance from the measuring section acts on the pelvic floor muscles, increasing muscle strength.
The processing and display unit extracts and displays information representing movement components of the pelvic floor muscles based on the signal obtained from the pressure-sensitive sensor during training. Therefore, with the training device of Patent Document 2, it is possible to objectively evaluate the training based on the movement of the pelvic floor muscles.

特許文献3には、弾性体によって作製された細長い円筒形状の管体と、可撓性チューブを通じて管体に連通された圧力計と、を備えた訓練装置が開示されている。
特許文献3の訓練装置によって骨盤底筋を訓練するためには、管体を膣内に挿入し、膣内の管体を縮径させる要領で骨盤底筋を収縮させる動作を行う。骨盤底筋を収縮させると管体の弾性力(抗力)が骨盤底筋に作用するので筋力が高められる。
圧力計は、訓練時において、管体内の空気圧力を筋力として表示する。従って、特許文献3の訓練装置では、管体内の空気圧力に基づいて訓練(骨盤底筋の筋力)の客観的評価が行える。
Patent Document 3 discloses a training device that includes an elongated cylindrical tube made of an elastic body and a pressure gauge communicated with the tube through a flexible tube.
In order to train the pelvic floor muscles using the training device of Patent Document 3, the tube is inserted into the vagina, and the pelvic floor muscles are contracted in a manner that reduces the diameter of the tube inside the vagina. When the pelvic floor muscles are contracted, the elastic force (resistance) of the tube body acts on the pelvic floor muscles, increasing muscle strength.
The pressure gauge displays the air pressure inside the tube as muscle force during training. Therefore, with the training device of Patent Document 3, it is possible to objectively evaluate the training (muscle strength of the pelvic floor muscles) based on the air pressure inside the tube.

特許文献1の装置では、骨盤底筋の筋力を高めることができるものの、骨盤底筋の筋力を客観的に評価することは困難である。特許文献2の装置では、骨盤底筋の筋力を客観的に評価できるが、直腸内に挿入される測定部に電子部品(感圧センサ等)を取り付けていることから、使用者が不安を覚える恐れがある。加えて、直腸の内部に棒状の測定部を挿入することは困難である。特許文献3の装置では、骨盤底筋の筋力を客観的に評価できるが、管体と圧力計との間を可撓性のチューブによって連通しているため、使用時においてチューブや圧力計が邪魔になってしまう。
本発明は、このような事情に鑑みてなされたものであり、その目的は、骨盤底筋の筋力を表示する筋力表示装置の使い勝手の向上を図ることにある。
Although the device of Patent Document 1 can increase the muscle strength of the pelvic floor muscles, it is difficult to objectively evaluate the muscle strength of the pelvic floor muscles. Although the device disclosed in Patent Document 2 can objectively evaluate the muscle strength of the pelvic floor muscles, the user may feel uneasy because electronic components (pressure-sensitive sensors, etc.) are attached to the measurement section that is inserted into the rectum. There is a fear. In addition, it is difficult to insert a rod-shaped measuring part inside the rectum. The device of Patent Document 3 can objectively evaluate the muscle strength of the pelvic floor muscles, but since the tubular body and the pressure gauge are communicated through a flexible tube, the tube and pressure gauge may get in the way during use. Become.
The present invention has been made in view of these circumstances, and its purpose is to improve the usability of a muscle strength display device that displays the muscle strength of pelvic floor muscles.

The device includes a display section 40 that displays the muscle strength of the patient, and a mounting section 30 for attaching the display section 40 to the insertion section 20.
The insertion portion 20 includes a first piece 21 made of a narrow band-shaped plate material, and a second piece 21 made of a narrow band-shaped plate material and arranged opposite to the first piece 21 in a substantially V-shape with a space therebetween. It includes a piece 22 and a connecting piece 23 that connects the ends of the first piece 21 and the second piece 22 on the narrower side (tip side).
A first mounting piece 31 constituting the mounting portion 30 is integrally provided on the rear end side of the first piece 21, and a second mounting piece 32 constituting the mounting portion 30 is integrally provided on the rear end side of the second piece 22. It is set in. The first mounting piece 31 and the second mounting piece 32 extend continuously and curved outward from the rear end portions of the first piece 21 and the second piece 22, respectively. The first attachment piece 31 and the second attachment piece 32 are located outside the vagina VG with the insertion portion 20 inserted into the vagina VG, and are grasped by the user when attaching and detaching the muscle strength display device 1. .

表示部40は、第1取付片31と第2取付片32とに跨がって取り付けられており、骨盤底筋MSの収縮によって挿入部20が受けた外力の値を骨盤底筋MSの筋力として表示する。
例示した表示部40は、長手方向の一端部が閉塞された円筒形状の筒部41と、筒部41の他端開口から内部に挿入された丸棒形状の軸部42と、リング形状(円環形状)の指標体43とを備えている。筒部41は、第1係合突起33が嵌合することによって、第1取付片31に取り付けられており、その長手方向の他端41a(開口部)は第2取付片32側に向けて延びている。軸部42は、第2係合突起34が嵌合することによって、第2取付片32に取り付けられており、その長手方向の一端部を筒部41の内側空所41c内に進退自在に挿入している。なお、筒部41を第2取付片32に取り付け、軸部42を第1取付片31に取り付けてもよい。

Note that the cylindrical portion 41 may be attached to the second attachment piece 32 and the shaft portion 42 may be attached to the first attachment piece 31.
As shown in FIG. 3, the index body 43 is inserted through the shaft so that it is supported by the outer circumferential surface of the shaft 42 so as to be able to move forward and backward in the axial direction, and extends along the longitudinal direction of the shaft 42. It is relatively movable. A coil spring 50 (drag generating portion) is disposed within the inner cavity 41c of the cylindrical portion 41, and an end surface 50a of the coil spring 50 and an end surface of the shaft portion 42 (end surface 42d of the shaft body 42a) are in contact with each other. The shaft portion 42 is biased in a direction away from the cylindrical portion 41 by the coil spring 50 .
Note that the drag generating section is not limited to the coil spring 50, and various elastic bodies such as rubber and plate springs can be used.

次に、筋力表示装置1の使用方法の概略を説明する。
図7は、骨盤底筋の収縮時の状態を示す図、図9(a)は筋力表示装置の挿入前の状態を示す図、図9(b)は第1片と第2片の間隔が狭まった状態を示す図、図9(c)は筋力表示装置を膣外へ抜き取った後の状態を示す図である。
図9(a)に示すように、指標体43は、筋力表示装置1の使用に先立って筒部41の他端41aに接した位置(初期位置)に人手により配置される。使用者は、筋力表示装置1の使用時に、指標体43を初期位置に保持したまま挿入部20を連結片23側(折り返し部側)から膣VG内に挿入する。
図7に示すように、挿入部20の全体が膣VG内に挿入された状態で使用者が骨盤底筋MSを収縮させると、図9(b)に示すように、第1片21、及び第2片22には、第1片21と第2片22との間隔を狭める方向の外力Fが作用し、表示部40の軸部42が筒部41の内側空所41c内に押し込まれる。このとき、筒部41と軸部42との間に配置されたコイルバネ50が抗力を生成する。外力F(骨盤底筋MSの収縮力)がコイルバネ50の抗力に勝ると、第1片21と第2片22との間隔が狭められ、軸部42は筒部41の内側空所41cに進入する。
Next, an outline of how to use the muscle strength display device 1 will be explained.
FIG. 7 is a diagram showing the state when the pelvic floor muscles are contracted, FIG. 9(a) is a diagram showing the state before insertion of the muscle strength display device, and FIG. 9(b) is a diagram showing the state when the pelvic floor muscles are contracted. FIG. 9(c) is a diagram showing the narrowed state, and is a diagram showing the state after the muscle strength display device has been pulled out of the vagina.
As shown in FIG. 9A, the indicator body 43 is manually placed at a position (initial position) in contact with the other end 41a of the cylindrical portion 41 prior to use of the muscle strength display device 1. When using the muscle strength display device 1, the user inserts the insertion portion 20 into the vagina VG from the connecting piece 23 side (folded portion side) while holding the indicator body 43 at the initial position.
As shown in FIG. 7, when the user contracts the pelvic floor muscles MS with the entire insertion section 20 inserted into the vagina VG, the first piece 21 and An external force F acts on the second piece 22 in the direction of narrowing the distance between the first piece 21 and the second piece 22, and the shaft part 42 of the display part 40 is pushed into the inner cavity 41c of the cylindrical part 41. At this time, the coil spring 50 disposed between the cylindrical portion 41 and the shaft portion 42 generates a drag force. When the external force F (contraction force of the pelvic floor muscles MS) overcomes the resistance of the coil spring 50, the distance between the first piece 21 and the second piece 22 is narrowed, and the shaft portion 42 enters the inner space 41c of the cylindrical portion 41. do.

指標体43は、筒部41の他端41aに当接しているため、軸部42の内側空所41cへの進入に伴って軸部42の長手方向に沿って相対移動する。従って、指標体43の軸部42上の位置(指標体43の軸部42上での移動量)は、骨盤底筋MSの収縮時における第1片21と第2片22との間隔に応じて定まる。
そして、軸部42の内側空所41cへの進入は、外力Fとコイルバネ50の抗力とが釣り合うことにより停止する。
Since the index body 43 is in contact with the other end 41a of the cylindrical portion 41, it relatively moves along the longitudinal direction of the shaft portion 42 as it enters the inner space 41c of the shaft portion 42. Therefore, the position of the index body 43 on the shaft 42 (the amount of movement of the index body 43 on the shaft 42) depends on the distance between the first piece 21 and the second piece 22 when the pelvic floor muscles MS contract. It is determined.
Then, the shaft portion 42 stops entering the inner space 41c when the external force F and the drag force of the coil spring 50 are balanced.

使用者が骨盤底筋MSを弛緩させ、挿入部20が膣VGから抜き取られると、連結片23の弾性力、及びコイルバネ50の復元力によって第1片21と第2片22との間隔が拡がる。第1片21と第2片22との間隔が拡がると、表示部40の軸部42は反対方向(筒部41から離れる方向)に移動する。このとき、指標体43は、指標体43の内周面と軸部42の外周面との間の摩擦により、収縮時における位置を維持しつつ、軸部42と共に移動する。つまり、指標体43の内周面と軸部42の外周面との摩擦抵抗は、上記のような操作が可能となるように適切に設定する。
挿入部20が膣VGから抜き取られた状態において、指標体43の軸部42上の位置は、骨盤底筋MSの収縮によって挿入部20が受けた外力Fの値(骨盤底筋MSの筋力)を示す。従って、使用者は、指標体43の軸部42上の位置に基づいて、骨盤底筋MSの筋力を知ることができる。
以上の構成を備えた筋力表示装置1によれば、挿入部20が電子部品を備えておらず、且つ表示部40がチューブや圧力計を備えていないので、使い勝手の向上が図れる。
When the user relaxes the pelvic floor muscles MS and the insertion section 20 is removed from the vagina VG, the distance between the first piece 21 and the second piece 22 increases due to the elastic force of the connecting piece 23 and the restoring force of the coil spring 50. . When the distance between the first piece 21 and the second piece 22 increases, the shaft portion 42 of the display portion 40 moves in the opposite direction (direction away from the cylindrical portion 41). At this time, the index body 43 moves together with the shaft portion 42 while maintaining the position at the time of contraction due to friction between the inner circumferential surface of the index body 43 and the outer circumferential surface of the shaft portion 42 . That is, the frictional resistance between the inner circumferential surface of the indicator body 43 and the outer circumferential surface of the shaft portion 42 is appropriately set so as to enable the above-described operation.
When the insertion section 20 is removed from the vagina VG, the position of the index body 43 on the shaft section 42 is determined by the value of the external force F received by the insertion section 20 due to contraction of the pelvic floor muscles MS (muscle strength of the pelvic floor muscles MS). shows. Therefore, the user can know the muscle strength of the pelvic floor muscles MS based on the position of the index body 43 on the shaft portion 42.
According to the muscle strength display device 1 having the above configuration, the insertion section 20 does not include any electronic components, and the display section 40 does not include a tube or a pressure gauge, so that usability can be improved.

The insertion portion 20 is made of elastic resin and is formed integrally with the attachment portion 30. For convenience, the combination of the insertion section 20 and the attachment section 30 is also referred to as the main body section 10. The insertion portion 20 includes a first piece 21 and a second piece 22 that are connected in a substantially V-shape by a connecting piece 23 . Therefore, the distance between the first piece 21 and the second piece 22 is narrowest on the connecting piece 23 side, and gradually widens as it moves away from the connecting piece 23.

第1片21、及び第2片22は細幅帯状の板材であるが、図1中の拡大断面図に示すように、幅方向の中央が最も厚く、幅方向の両端に向けて漸次厚みが薄くなるように外表面が湾曲されている。同様に、連結片23の外表面も円弧形状に湾曲されている。第1片21の外表面、第2片22の外表面、及び連結片23の外表面を湾曲させたことにより、挿入部20を膣VG内に挿入するときに、使用者に刺激を与え難くしている。
第1片21、及び第2片22の幅は、例えば15mm乃至30mmであり、連結片23を含めた挿入部20の長さは85mm乃至120mmであるが、膣VGへの挿入に支障がなければサイズは限定されない。また、第1片21と第2片22との間の交差角度(内角)は15度乃至25度であるが、膣VGへの挿入に支障がなければ交差角度は限定されない。

Similarly, the outer surface of the connecting piece 23 is also curved into an arc shape. By curving the outer surface of the first piece 21, the outer surface of the second piece 22, and the outer surface of the connecting piece 23, it is difficult to irritate the user when inserting the insertion section 20 into the vagina VG. are doing.
The width of the first piece 21 and the second piece 22 is, for example, 15 mm to 30 mm, and the length of the insertion part 20 including the connecting piece 23 is 85 mm to 120 mm, but it is important that there is no difficulty in inserting it into the vagina VG. However, the size is not limited. Further, the intersecting angle (inner angle) between the first piece 21 and the second piece 22 is 15 degrees to 25 degrees, but the intersecting angle is not limited as long as it does not hinder insertion into the vagina VG.

図3に示すように、本体部10(挿入部20と取付部30の組)は、主に本体部10の外側の表面を形成する第1の樹脂RS1と、主に本体部10の中心部分や内側の表面を形成する第2の樹脂RS2とによって形成されている。本実施形態において、本体部10は、インサート成型によって作製されている。
第1の樹脂RS1は、使用者の膣VGと直接接触する部分であることから、第2の樹脂RS2と比較して表面の摩擦が小さく、且つ柔軟な樹脂で作製されている。本実施形態において、第1の樹脂RS1の表面にはシボ加工が施されている。
第2の樹脂RS2は本体部10における芯材として機能するものであり、コイルバネ50が生成する力に対抗し得る剛性を備えた樹脂によって作製されている。

As shown in FIG. 3, the main body part 10 (a set of the insertion part 20 and the attachment part 30) mainly consists of a first resin RS1 that forms the outer surface of the main body part 10, and a center part of the main body part 10. and a second resin RS2 forming the inner surface. In this embodiment, the main body portion 10 is manufactured by insert molding.
Since the first resin RS1 is a part that comes into direct contact with the user's vagina VG, it is made of a flexible resin that has less surface friction than the second resin RS2. In this embodiment, the surface of the first resin RS1 is textured.
The second resin RS2 functions as a core material in the main body portion 10, and is made of a resin having a rigidity capable of resisting the force generated by the coil spring 50.
The types of the first resin RS1 and the second resin RS2 are not particularly limited as long as they satisfy these conditions. Note that the main body portion 10 may be made of one type of resin that has both the characteristics of the first resin RS1 and the characteristics of the second resin RS2.

取付部30は、第1片21の後端(連結片23とは反対側の端)から連続して設けられた第1取付片31と、第2片22の後端(連結片23とは反対側の端)から連続して設けられた第2取付片32と、第1取付片31における挿入部20側の表面とは反対側の表面に突設された第1係合突起33と、第2取付片32における挿入部20側の表面とは反対側の表面に突設された第2係合突起34と、を備えている。
第1取付片31は第1片21の後端から外側へ向けて拡開するように延びており、第2取付片32は第2片22の後端からV字の拡開方向に延びている。本実施形態において、第1取付片31の長さは第2取付片32の長さよりも長い。第1取付片31において第1係合突起33よりも外側へ延出された端部は、使用者の手指によって把持される把持部35である。
第1係合突起33は球形状の突起であり、第1取付片31と一体に設けられている。第2係合突起34もまた球形状の突起であり、第2取付片32と一体に設けられている。
The mounting portion 30 includes a first mounting piece 31 that is continuously provided from the rear end of the first piece 21 (an end opposite to the connecting piece 23), and a rear end of the second piece 22 (the end opposite to the connecting piece 23). a second attachment piece 32 provided continuously from the opposite end); a first engagement protrusion 33 protruding from the surface of the first attachment piece 31 opposite to the surface on the insertion portion 20 side; A second engagement protrusion 34 is provided to protrude from the surface of the second attachment piece 32 on the side opposite to the surface on the insertion portion 20 side.
The first mounting piece 31 extends outward from the rear end of the first piece 21, and the second mounting piece 32 extends from the rear end of the second piece 22 in the direction in which the V-shape expands. There is. In this embodiment, the length of the first attachment piece 31 is longer than the length of the second attachment piece 32. An end portion of the first attachment piece 31 that extends outward beyond the first engagement protrusion 33 is a grip portion 35 that is gripped by the user's fingers.
The first engagement protrusion 33 is a spherical protrusion, and is provided integrally with the first attachment piece 31. The second engagement protrusion 34 is also a spherical protrusion, and is provided integrally with the second attachment piece 32.

次に、表示部40について説明する。図2及び図3に示すように、表示部40は、筒部41と、軸部42と、指標体43とを備えている。
筒部41は、長手方向の一端が閉塞され、他端41aが開放された円筒形状をしている。筒部41の一端側の端面は半球形状をしており、一端側部分の外周面には球形状の第1係合凹所41bが設けられている。第1係合凹所41bには、第1取付片31の第1係合突起33が着脱自在に嵌合される。また、筒部41の内側空所41cにはコイルバネ50(抗力生成部)が配置されている。
Next, the display section 40 will be explained. As shown in FIGS. 2 and 3, the display section 40 includes a cylinder section 41, a shaft section 42, and an indicator body 43.
The cylindrical portion 41 has a cylindrical shape with one longitudinal end closed and the other end 41a open. The end surface on the one end side of the cylindrical portion 41 has a hemispherical shape, and a spherical first engagement recess 41b is provided on the outer peripheral surface of the one end side portion. The first engagement protrusion 33 of the first attachment piece 31 is removably fitted into the first engagement recess 41b. Further, a coil spring 50 (drag force generating section) is arranged in the inner cavity 41c of the cylindrical section 41.

軸部42は、円筒形状の軸本体42aと、軸本体42aの他端に軸本体42aと一体に設けられた軸基部42bとを備えている。軸本体42aは、筒部41の内側空所41cに挿入可能な直径に作製されている。例えば、軸本体42aの直径は、筒部41の内径(内側空所41cの直径)と同じか、クリアランスの分だけ筒部41の内径よりも小さく定められている。
軸基部42bは、軸本体42aの直径よりも一回り大きな直径を有しており、軸本体42aとは反対側の端面は半球形状をしている。軸基部42bの外周面には、球形状の第2係合凹所42cが設けられている。第2係合凹所42cには、第2取付片32の第2係合突起34が着脱自在に嵌合される。
The shaft portion 42 includes a cylindrical shaft body 42a and a shaft base portion 42b provided integrally with the shaft body 42a at the other end of the shaft body 42a. The shaft body 42a is made to have a diameter that allows it to be inserted into the inner cavity 41c of the cylindrical portion 41. For example, the diameter of the shaft body 42a is set to be the same as the inner diameter of the cylindrical portion 41 (diameter of the inner cavity 41c), or smaller than the inner diameter of the cylindrical portion 41 by an amount of clearance.
The shaft base 42b has a diameter that is one size larger than the diameter of the shaft main body 42a, and the end surface opposite to the shaft main body 42a has a hemispherical shape. A spherical second engagement recess 42c is provided on the outer peripheral surface of the shaft base 42b. The second engagement protrusion 34 of the second attachment piece 32 is removably fitted into the second engagement recess 42c.

図3に示すように、表示部40が取付部30に取り付けられた状態において、軸本体42aの一端部は筒部41の内側空所41c内に挿入され、軸本体42aの端面42dはコイルバネ50の端面50aに当接している。
従って、挿入部20に対して外力Fが作用し、連結片23が変形して第1片21と第2片22との間隔が狭められると、軸本体42aが筒部41の内側空所41c内に進入してコイルバネ50を押し縮める。軸本体42aは、コイルバネ50、及び連結片23の合力よりも外力Fが大きい状態では、筒部41の内側空所41cの内奥方向へ進入する。また、軸本体42aは、コイルバネ50、及び連結片23の合力と外力Fとが釣り合った状態では、内側空所41cへの進入が停まる。
As shown in FIG. 3, when the display section 40 is attached to the mounting section 30, one end of the shaft body 42a is inserted into the inner cavity 41c of the cylindrical section 41, and the end surface 42d of the shaft body 42a is connected to the coil spring 50. It is in contact with the end surface 50a of.
Therefore, when the external force F acts on the insertion portion 20 and the connecting piece 23 is deformed to narrow the distance between the first piece 21 and the second piece 22, the shaft body 42a is moved into the inner cavity 41c of the cylindrical portion 41. the coil spring 50. The shaft body 42a enters into the inner cavity 41c of the cylindrical portion 41 in a state where the external force F is greater than the resultant force of the coil spring 50 and the connecting piece 23. Further, the shaft body 42a stops entering the inner cavity 41c in a state where the resultant force of the coil spring 50 and the connecting piece 23 and the external force F are balanced.

指標体43は円形リング形状をしており、指標体43の内側空所41cには軸本体42aが挿通されている。
指標体43の内径は、軸本体42aの外径と同じか、クリアランスの分だけ軸本体42aの外径よりも大きく、且つ筒部41や軸基部42bの外径よりも小さい。このため、指標体43は、軸本体42aの上を長手方向に沿って相対移動自在である。
指標体43と軸本体42aは、筋力表示装置1を傾けた時に指標体43が自重によって移動しない程度の摩擦を発生する構成を備えている。例えば、指標体43や軸本体42aを必要な摩擦力が得られる材質の樹脂で作製したり、指標体43の内周面及び軸本体42aの外周面の表面粗さを必要な摩擦力が得られる粗さに仕上げている。
The indicator body 43 has a circular ring shape, and the shaft body 42a is inserted into the inner cavity 41c of the indicator body 43.
The inner diameter of the indicator body 43 is the same as the outer diameter of the shaft body 42a, or larger than the outer diameter of the shaft body 42a by the amount of clearance, and smaller than the outer diameter of the cylindrical portion 41 and the shaft base 42b. Therefore, the indicator body 43 is relatively movable along the longitudinal direction on the shaft body 42a.
The indicator body 43 and the shaft body 42a are configured to generate friction to the extent that the indicator body 43 does not move due to its own weight when the muscle strength display device 1 is tilted. For example, the indicator body 43 and the shaft body 42a may be made of a resin material that provides the necessary frictional force, or the surface roughness of the inner circumferential surface of the indicator body 43 and the outer circumferential surface of the shaft body 42a may be adjusted to obtain the necessary frictional force. It is finished to a roughness that can be used.

従って、指標体43を筒部41に当接させた状態で第1片21と第2片22との間隔が狭められると、軸本体42aは筒部41の内側空所41cに進入し、指標体43は軸本体42a上を軸基部42b側に相対移動する。その後、第1片21と第2片22との間隔が拡げられると、軸本体42aが筒部41から離れる方向に移動するが、指標体43は軸本体42aと共に筒部41から離れる方向に移動する。
このように、指標体43の軸本体42a上の位置は、第1片21と第2片22とが近接した状態(骨盤底筋MSの収縮時の状態)における両片21、22間の間隔に基づいて定められる。
第1片21と第2片22の近接時における両片21、22間の間隔は骨盤底筋MSの筋力に応じて変わるため、指標体43の軸本体42a上の位置は骨盤底筋MSの筋力を示している。
Therefore, when the distance between the first piece 21 and the second piece 22 is narrowed with the indicator body 43 in contact with the cylindrical part 41, the shaft body 42a enters the inner space 41c of the cylindrical part 41, and the indicator The body 43 relatively moves on the shaft body 42a toward the shaft base 42b. After that, when the distance between the first piece 21 and the second piece 22 is widened, the shaft main body 42a moves in a direction away from the cylindrical part 41, but the indicator body 43 moves in the direction away from the cylindrical part 41 together with the shaft main body 42a. do.
In this way, the position of the index body 43 on the shaft body 42a is determined by the distance between the first piece 21 and the second piece 22 when they are close to each other (when the pelvic floor muscles MS are contracted). It is determined based on.
Since the distance between the first piece 21 and the second piece 22 when they are close to each other changes depending on the muscle strength of the pelvic floor muscles MS, the position of the index body 43 on the shaft body 42a is Shows muscle strength.

本実施形態において、表示部40は、本体部10(挿入部20と取付部30の組)に対して着脱自在に構成されている。このため、筋力表示装置1の使用前後において、表示部40を本体部10から取り外すことにより、本体部10を単体で洗浄(例えば水洗い)することができる。これにより、表示部40の内部に水が浸入し、コイルバネ50が錆びてしまう等の不都合が抑制される。 In this embodiment, the display section 40 is configured to be detachable from the main body section 10 (the set of the insertion section 20 and the attachment section 30). Therefore, by removing the display section 40 from the main body section 10 before and after using the muscle strength display device 1, the main body section 10 can be washed alone (eg, washed with water). This prevents inconveniences such as water entering the display section 40 and causing the coil spring 50 to rust.

図4は、第1の表示部40Xと第2の表示部40Yとの交換作業を説明する図である。図4には、圧縮時において標準的な抗力を発生する第1のコイルバネ50X(第1の抗力生成部)を収容した第1の表示部40Xと、第1のコイルバネ50Xとは圧縮時における抗力が相違する第2のコイルバネ50Y(第2の抗力生成部)を収容した第2の表示部40Yとを示している。
第1の表示部40Xと第2の表示部40Yは、コイルバネ50X、50Y以外の構成、すなわち筒部41、軸部42、及び指標体43の構成は同じである。このため、第1の表示部40Xと第2の表示部40Yは本体部10(取付部30)に対して交換可能に取り付けられる。
FIG. 4 is a diagram illustrating the replacement work of the first display section 40X and the second display section 40Y. FIG. 4 shows a first display section 40X that accommodates a first coil spring 50X (first drag generating section) that generates a standard drag force when compressed; A second display section 40Y that accommodates a second coil spring 50Y (second drag generating section) having different values is shown.
The first display section 40X and the second display section 40Y have the same structure except for the coil springs 50X and 50Y, that is, the structure of the cylinder section 41, the shaft section 42, and the index body 43. Therefore, the first display section 40X and the second display section 40Y are attached to the main body section 10 (attachment section 30) so that they can be replaced.

第2の表示部40Yを本体部10に取り付けた筋力表示装置1は、第1の表示部40Xを本体部10に取り付けた筋力表示装置1と比較して、第1片21と第2片22との間隔を狭めるために必要な外力Fが異なる。
例えば、第2のコイルバネ50Yとして、第1のコイルバネ50Xよりも圧縮時における抗力が大きいものを用いた場合には、第1片21と第2片22との間隔を狭めるために必要な外力F(骨盤底筋MSの筋力)も大きくなる。従って、第1の表示部40Xと第2の表示部40Yとを本体部10に対して選択的に取り付けて使用することにより、筋力の測定範囲を拡張することができる。また、第2の表示部40Yを本体部10に取り付けて使用すると、第1の表示部40Xを本体部10に取り付けて使用したときよりも、骨盤底筋MSの筋力を増強させる効果が見込める。
なお、図4の例では2種類の表示部40X、40Yを例示したが、この構成に限定されない。例えば、圧縮時における抗力が互いに異なるコイルバネ50を有した3種類以上の表示部40を使用することもできる。
The muscle strength display device 1 in which the second display portion 40Y is attached to the main body portion 10 is different from the muscle strength display device 1 in which the first display portion 40X is attached to the main body portion 10. The external force F required to narrow the distance between the two is different.
For example, if the second coil spring 50Y has a larger resistance during compression than the first coil spring 50X, the external force F required to narrow the distance between the first piece 21 and the second piece 22 is (The strength of the pelvic floor muscles MS) also increases. Therefore, by selectively attaching and using the first display section 40X and the second display section 40Y to the main body section 10, it is possible to expand the measurement range of muscle strength. Further, when the second display section 40Y is attached to the main body section 10 and used, the effect of increasing the muscle strength of the pelvic floor muscles MS can be expected to be greater than when the first display section 40X is attached to the main body section 10 and used.
In addition, although two types of display parts 40X and 40Y were illustrated in the example of FIG. 4, it is not limited to this structure. For example, it is also possible to use three or more types of display sections 40 having coil springs 50 that have different resistance forces when compressed.

<筋力表示装置1の使用方法>
次に、筋力表示装置1の使用方法について説明する。図5は筋力表示装置1の膣VGへの挿入前の状態を示す図、図6は筋力表示装置1を膣VG内に挿入した状態を示す図、図8は筋力表示装置1を膣VG外へ抜き取った状態を示す図である。
図9(a)に示すように、指標体43は、筋力表示装置1の使用に先立ち、筒部41の他端41aに当接するまで軸本体42aに沿って移動する。指標体43の位置決めを完了した後で挿入部20を膣VGに挿入する。このとき、図5に示すように、挿入部20の連結片23(折り返し部分)を膣口(膣前庭)VOの手前に位置付け、挿入部20を膣VG内にゆっくりと挿入する。第1実施形態に係る筋力表示装置1では、連結片23の外表面が円弧形状に湾曲しており、且つ第1片21、及び第2片22の外表面も湾曲されているため、挿入部20の膣VG内への挿入過程において使用者に与える刺激を軽減できる。
<How to use the muscle strength display device 1>
Next, how to use the muscle strength display device 1 will be explained. FIG. 5 is a diagram showing the state of the muscle strength display device 1 before insertion into the vagina VG, FIG. 6 is a diagram showing the state of the muscle strength display device 1 inserted into the vagina VG, and FIG. 8 is a diagram showing the state of the muscle strength display device 1 being inserted outside the vagina VG. It is a figure which shows the state pulled out.
As shown in FIG. 9(a), before the muscle strength display device 1 is used, the indicator body 43 moves along the shaft body 42a until it comes into contact with the other end 41a of the cylindrical portion 41. As shown in FIG. After completing the positioning of the index body 43, the insertion section 20 is inserted into the vagina VG. At this time, as shown in FIG. 5, the connecting piece 23 (folded part) of the insertion section 20 is positioned in front of the vaginal opening (vaginal vestibule) VO, and the insertion section 20 is slowly inserted into the vagina VG. In the muscle strength display device 1 according to the first embodiment, the outer surface of the connecting piece 23 is curved in an arc shape, and the outer surfaces of the first piece 21 and the second piece 22 are also curved, so that the insertion portion The stimulation given to the user during the insertion process into the vagina VG of 20 can be reduced.

図6に示すように、取付部30(各取付片31、32)が膣口VOに当たるまで、挿入部20を膣VG内に挿入する。この挿入状態において、連結片23は、骨盤底筋MSよりも膣VGの内奥側に位置していると推定される。その後、図7に示すように骨盤底筋MSを収縮させる。骨盤底筋MSの収縮に伴って外力Fが作用し、図9(b)に示すように両片21、22間の間隔が狭められる。
両片21、22間の間隔が狭められると、表示部40において軸本体42aが筒部41の内側空所41cに進入し、指標体43の軸本体42a上の位置が移動する。すなわち、指標体43の軸本体42aにおける長手方向の位置は、軸本体42aの内側空所41cへの挿入深度に応じて定められ、挿入深度が深い程に軸基部42bに近い位置となる。
As shown in FIG. 6, the insertion section 20 is inserted into the vagina VG until the attachment section 30 (each attachment piece 31, 32) hits the vaginal opening VO. In this inserted state, the connecting piece 23 is estimated to be located deeper inside the vagina VG than the pelvic floor muscles MS. Thereafter, the pelvic floor muscles MS are contracted as shown in FIG. As the pelvic floor muscles MS contract, an external force F acts, and the distance between the pieces 21 and 22 narrows as shown in FIG. 9(b).
When the distance between the two pieces 21 and 22 is narrowed, the shaft main body 42a enters the inner space 41c of the cylindrical portion 41 in the display section 40, and the position of the indicator body 43 on the shaft main body 42a moves. That is, the longitudinal position of the indicator body 43 in the shaft body 42a is determined according to the insertion depth of the shaft body 42a into the inner cavity 41c, and the deeper the insertion depth, the closer the position is to the shaft base 42b.

使用者は、骨盤底筋MSを十分に収縮した後に骨盤底筋MSを弛緩し、図8に示すように挿入部20を膣VGから抜き取る。図9(c)に示すように、膣VGから抜き取られた筋力表示装置1は、外力Fが作用していないため、連結片23の弾性力とコイルバネ50の復元力とによって両片21、22間の間隔が拡がった状態になる。
軸本体42aは両片21、22間の間隔の拡がりに伴って筒部41から離れる方向に移動し、指標体43は軸部42との間の摩擦によって収縮時における位置を維持しつつ、軸部42と共に移動する。
すなわち、指標体43の指標体43の軸本体42a上の位置は、両片21、22間の間隔が拡がっても変わらない。このため、両片21、22間の間隔が拡がった状態において、指標体43の軸本体42a上の位置は、骨盤底筋MSの収縮によって挿入部20が受けた外力Fの値、すなわち骨盤底筋MSの筋力を示す。
従って、使用者は、指標体43の軸部42上の位置に基づいて、骨盤底筋MSの筋力を知ることができる。
After sufficiently contracting the pelvic floor muscles MS, the user relaxes the pelvic floor muscles MS and withdraws the insertion section 20 from the vagina VG as shown in FIG. As shown in FIG. 9(c), since the external force F is not acting on the muscle force display device 1 removed from the vagina VG, both pieces 21 and 22 are affected by the elastic force of the connecting piece 23 and the restoring force of the coil spring 50. The gap between them becomes wider.
The shaft body 42a moves away from the cylindrical portion 41 as the distance between the two pieces 21 and 22 widens, and the index body 43 maintains its position when contracted due to friction between the shaft portion 42 and the shaft. 42.
That is, the position of the indicator body 43 on the shaft body 42a does not change even if the distance between the two pieces 21 and 22 increases. Therefore, when the distance between the two pieces 21 and 22 is widened, the position of the index body 43 on the shaft body 42a is determined by the value of the external force F received by the insertion section 20 due to the contraction of the pelvic floor muscles MS, that is, the pelvic floor The muscle strength of muscle MS is shown.
Therefore, the user can know the muscle strength of the pelvic floor muscles MS based on the position of the index body 43 on the shaft portion 42.

<第1実施形態の変形例に係る筋力表示装置1’>
図10に示す第1実施形態の変形例に係る筋力表示装置1’は、第1実施形態に係る筋力表示装置1と同様に、本体部10’(挿入部20’、取付部30’)と、挿入部20’に対して着脱自在に取り付けられた表示部40’と、表示部40’が有する筒部41’の内側空所41c’に配置されたコイルバネ50’とを備えている。
変形例に係る筋力表示装置1’は、特に、第1片21’、及び第2片22’が互いに平行に配置され、且つ連結片23’の曲率が第1実施形態に係る連結片23よりも大きい点が、第1実施形態に係る筋力表示装置1と相違している。また、軸部42’の軸本体42a’が第1実施形態に係る軸本体42aよりも細く、且つ指標体43’がC型のプレートによって構成されている点も、第1実施形態に係る筋力表示装置1と相違している。
以上の構成を備えた筋力表示装置1’では、第1片21’、及び第2片22’が互いに平行に配置されているため、外力Fが加わった状態において挿入部20’が膣VGの外に抜け難いという利点、及び連結片23’の曲率が大きいため、連結片23’の内周面の清掃が容易であるという利点がある。
<Strength display device 1' according to a modification of the first embodiment>
Similarly to the muscle strength display device 1 according to the first embodiment, the muscle strength display device 1′ according to the modification of the first embodiment shown in FIG. , a display section 40' detachably attached to the insertion section 20', and a coil spring 50' disposed in an inner cavity 41c' of a cylindrical section 41' included in the display section 40'.
In particular, the muscle strength display device 1' according to the modified example has the first piece 21' and the second piece 22' arranged in parallel to each other, and the curvature of the connecting piece 23' is greater than that of the connecting piece 23 according to the first embodiment. This is different from the muscle strength display device 1 according to the first embodiment in that the muscle strength display device 1 is also larger. Further, the fact that the shaft body 42a' of the shaft portion 42' is thinner than the shaft body 42a according to the first embodiment, and the index body 43' is constituted by a C-shaped plate is also advantageous. This is different from display device 1.
In the muscle strength display device 1' having the above configuration, the first piece 21' and the second piece 22' are arranged parallel to each other, so that the insertion portion 20' is inserted into the vagina VG when an external force F is applied. It has the advantage that it is difficult to come off, and because the curvature of the connecting piece 23' is large, the inner circumferential surface of the connecting piece 23' can be easily cleaned.

<第2実施形態に係る筋力表示装置1A>
図11に示す第2実施形態に係る筋力表示装置1Aは、図10の筋力表示装置1’と同様に構成された本体部10Aを備え、且つ表示部40Aがラチェット構造を有している点が、第1実施形態の筋力表示装置1と相違している。
第2実施形態に係る筋力表示装置1Aでは、挿入部20Aの連結片23Aが抗力生成部に対応し、外力Fに対する抗力を生成する。表示部40Aは、第1片21Aの内表面において第2片22Aに向けて突設された爪部41Aと、第2片22Aの内表面に第1片21Aに向けて突設された溝部42A(セレーション)とを備えている。
<Strength display device 1A according to second embodiment>
A muscle strength display device 1A according to the second embodiment shown in FIG. 11 includes a main body portion 10A configured similarly to the muscle strength display device 1′ of FIG. 10, and a display portion 40A has a ratchet structure. , which is different from the muscle strength display device 1 of the first embodiment.
In the muscle strength display device 1A according to the second embodiment, the connecting piece 23A of the insertion section 20A corresponds to a drag generation section and generates a drag force against the external force F. The display section 40A includes a claw portion 41A that protrudes toward the second piece 22A on the inner surface of the first piece 21A, and a groove portion 42A that protrudes toward the first piece 21A on the inner surface of the second piece 22A. (serrations).

爪部41Aは、角柱状の爪部本体411Aと、爪部本体411Aの先端部において下向きに突設された略三角柱形状の爪412Aとを備えている。爪部41Aは樹脂製であり、本実施形態では第1片21Aと一体に成型される。
溝部42Aは角柱状の溝部本体421Aと、溝部本体421Aの上面に複数形成された鋸刃形状の溝422Aとを備えている。各溝422Aは、爪412Aが嵌合可能な形状であり、爪412Aの第2片22A側への移動は許容する斜面423A(第1面)と、反対側(第1片21A側)への移動を阻止する垂下面424A(第2面)とによって形成されている。溝部42Aは樹脂製であり、本実施形態では第2片22Aと一体に成型される。
The claw portion 41A includes a prismatic claw main body 411A and a substantially triangular prism-shaped claw 412A that projects downward at the tip of the claw main body 411A. The claw portion 41A is made of resin, and in this embodiment is molded integrally with the first piece 21A.
The groove portion 42A includes a prismatic groove main body 421A and a plurality of saw blade-shaped grooves 422A formed on the upper surface of the groove main body 421A. Each groove 422A has a shape in which the claw 412A can fit, and has a slope 423A (first surface) that allows the claw 412A to move toward the second piece 22A side, and a slope 423A (first surface) that allows the claw 412A to move toward the second piece 22A side, and a slope 423A (first surface) that allows the claw 412A to move toward the second piece 22A side. It is formed by a hanging surface 424A (second surface) that prevents movement. The groove portion 42A is made of resin, and in this embodiment is molded integrally with the second piece 22A.

第2実施形態に係る筋力表示装置1Aでは、挿入部20Aの全体が膣VG内に挿入された状態で使用者が骨盤底筋MSを収縮させると、第1片21Aと第2片22Aには互いの間隔を狭める方向の外力Fが作用し、連結片23A(抗力生成部)が抗力を生成する。
外力Fが抗力よりも大きいと、両片21A、22A間の間隔が狭められ、爪部41Aが溝部42Aの上を第2片22A側に向けて移動する。このとき、爪部41Aの爪412Aは、溝部本体421Aの上面に設けた各溝422Aを乗り越えながら移動する。
In the muscle strength display device 1A according to the second embodiment, when the user contracts the pelvic floor muscles MS with the entire insertion portion 20A inserted into the vagina VG, the first piece 21A and the second piece 22A An external force F acts in a direction that narrows the distance between them, and the connecting piece 23A (drag generation section) generates a drag force.
When the external force F is larger than the drag force, the distance between the two pieces 21A and 22A is narrowed, and the claw portion 41A moves on the groove portion 42A toward the second piece 22A side. At this time, the claws 412A of the claw portion 41A move over each groove 422A provided on the upper surface of the groove main body 421A.

使用者が骨盤底筋MSを弛緩させ、挿入部20Aが膣VGから抜き取られると、連結片23Aの復元力が第1片21Aと第2片22Aに作用するが、爪412Aが溝422Aに引っ掛かるため、両片21A、22A間の間隔は狭められたまま維持される。
従って、爪412Aの位置(爪412Aが引っ掛かっている溝422A)は、骨盤底筋MSの収縮によって挿入部20Aが受けた外力Fの値(骨盤底筋MSの筋力)を示す。そして、使用者は、爪412Aの位置に基づいて、骨盤底筋MSの筋力を知ることができる。
When the user relaxes the pelvic floor muscles MS and the insertion section 20A is removed from the vagina VG, the restoring force of the connecting piece 23A acts on the first piece 21A and the second piece 22A, but the claw 412A gets caught in the groove 422A. Therefore, the distance between the two pieces 21A and 22A remains narrow.
Therefore, the position of the claw 412A (the groove 422A in which the claw 412A is caught) indicates the value of the external force F (muscle strength of the pelvic floor muscle MS) that the insertion portion 20A receives due to the contraction of the pelvic floor muscle MS. Then, the user can know the muscle strength of the pelvic floor muscles MS based on the position of the nail 412A.

<第2実施形態の変形例に係る筋力表示装置1B>
図12に示す第2実施形態の変形例に係る筋力表示装置1Bは、特に、挿入部20Bと表示部40Bの構成が前述した各筋力表示装置1、1’、1Aと相違している。
例えば、挿入部20Bに関しては、第1片21Bと第2片22Bとをヒンジ機構23Bによって連結し、ヒンジ機構23Bを中心に開閉自在である点が相違している。また、表示部40Bに関しては、複数の大径部411B及び複数の小径部412Bを軸方向に沿って交互に設けた軸部41Bと、軸部41Bが挿通され、且つ弾性変形される挿通孔421Bが設けられた孔部42Bとを備えている点が相違している。
<Muscle strength display device 1B according to a modification of the second embodiment>
A muscle strength display device 1B according to a modification of the second embodiment shown in FIG. 12 is different from the muscle strength display devices 1, 1', and 1A described above particularly in the configurations of an insertion section 20B and a display section 40B.
For example, the insertion portion 20B is different in that the first piece 21B and the second piece 22B are connected by a hinge mechanism 23B and can be opened and closed around the hinge mechanism 23B. Regarding the display section 40B, the shaft section 41B includes a plurality of large diameter sections 411B and a plurality of small diameter sections 412B alternately provided along the axial direction, and an insertion hole 421B into which the shaft section 41B is inserted and elastically deformed. The difference is that the hole 42B is provided with a hole 42B.

第2実施形態の変形例に係る筋力表示装置1Bでは、表示部40Bが抗力生成部としても機能する。例えば、骨盤底筋MSの収縮によって第1片21Bと第2片22Bに互いの間隔を狭める方向の外力Fが作用すると、大径部411Bと挿通孔421Bとが当接して抗力を生成する。そして、外力Fが抗力に勝って挿通孔421Bが大径部411Bを通過すると、挿通孔421Bは隣の小径部412Bに移動して次段の大径部411Bに当接する。以降は、上述の外力Fと抗力とが釣り合うまで挿通孔421Bが大径部411Bを順に通過する。 In the muscle strength display device 1B according to the modification of the second embodiment, the display section 40B also functions as a drag generation section. For example, when an external force F acts on the first piece 21B and the second piece 22B in the direction of narrowing the distance between them due to contraction of the pelvic floor muscles MS, the large diameter portion 411B and the insertion hole 421B come into contact with each other to generate a drag force. When the external force F overcomes the drag and the insertion hole 421B passes through the large diameter section 411B, the insertion hole 421B moves to the adjacent small diameter section 412B and comes into contact with the next large diameter section 411B. Thereafter, the insertion hole 421B passes through the large diameter portion 411B in order until the above-mentioned external force F and the drag force are balanced.

使用者が骨盤底筋MSを弛緩させても、挿通孔421Bと軸部41Bの位置関係は第1片21Bと第2片22Bの間隔が狭められた状態を維持する。このため、孔部42B(挿通孔421B)の軸部41B上の位置は、骨盤底筋MSの収縮によって挿入部20Bが受けた外力Fの値(骨盤底筋MSの筋力)を示す。従って、使用者は、孔部42Bの軸部41B上の長手方向位置に基づいて、骨盤底筋MSの筋力を知ることができる。
なお、筋力表示装置1Bでは、挿通孔421Bの軸部41B上の位置を膣VGへの挿入前に調整しておくことにより、各片21B、22Bの間隔を使用者に適した間隔に定めることができる。
Even if the user relaxes the pelvic floor muscles MS, the positional relationship between the insertion hole 421B and the shaft portion 41B maintains a state in which the distance between the first piece 21B and the second piece 22B is narrowed. Therefore, the position of the hole 42B (insertion hole 421B) on the shaft portion 41B indicates the value of the external force F (muscle strength of the pelvic floor muscle MS) that the insertion portion 20B receives due to contraction of the pelvic floor muscle MS. Therefore, the user can know the muscle strength of the pelvic floor muscles MS based on the longitudinal position of the hole 42B on the shaft 41B.
In addition, in the muscle strength display device 1B, by adjusting the position of the insertion hole 421B on the shaft portion 41B before insertion into the vagina VG, the interval between each piece 21B and 22B can be determined to be an interval suitable for the user. I can do it.

<第3実施形態に係る筋力表示装置1C>
図13に示す第3実施形態に係る筋力表示装置1Cは、特に、指針式の表示部40Cを備えている点が前述した各筋力表示装置1、1’、1A、1Bと相違している。
第3実施形態に係る筋力表示装置1Cにおいて挿入部20Cは、第1片21Cと第2片22Cとをヒンジ機構23Cによって開閉自在に連結し、第1片21Cと第2片22Cとの間に抗力生成部材としてのコイルバネ50Cを取り付けている。コイルバネ50Cは、挿入部20Cの先端部(ヒンジ機構23C側の部分)からの距離を複数段階で変更可能に取り付けられている。この構成により、筋力表示装置1Cでは、コイルバネ50Cの取り付け位置(挿入部20Cの先端部からの距離)に応じて、抗力の大きさを変更することができる。
第1片21Cの後端側側面には第1把手31Cを側方に延出して設け、第2片22Cの後端側側面には第2把手32Cを側方に延出して設けている。これらの第1把手31C、及び第2把手32Cは使用者によって把持される部分であり、挿入部20Cが膣VG内に挿入された状態において膣VGの外部に位置する。
<Muscle strength display device 1C according to third embodiment>
A muscle strength display device 1C according to the third embodiment shown in FIG. 13 is different from the muscle strength display devices 1, 1', 1A, and 1B described above in that it includes a pointer-type display section 40C.
In the muscle strength display device 1C according to the third embodiment, the insertion portion 20C connects the first piece 21C and the second piece 22C so as to be openable and closable by a hinge mechanism 23C, and has a space between the first piece 21C and the second piece 22C. A coil spring 50C is attached as a drag generating member. The coil spring 50C is attached so that the distance from the distal end portion (the portion on the hinge mechanism 23C side) of the insertion portion 20C can be changed in multiple stages. With this configuration, in the muscle force display device 1C, the magnitude of the drag force can be changed depending on the attachment position of the coil spring 50C (distance from the distal end of the insertion portion 20C).
A first handle 31C is provided extending laterally on the side surface on the rear end side of the first piece 21C, and a second handle 32C is provided extending laterally on the side surface on the rear end side of the second piece 22C. These first handle 31C and second handle 32C are parts that are held by the user, and are located outside the vagina VG when the insertion section 20C is inserted into the vagina VG.

表示部40Cは、第1片21Cの後端部(挿入端とは反対側の端部)に設けられたラックギア41Cと、第2片22Cの後端部(挿入端とは反対側の端部)に設けられたピニオンギア42Cと、ピニオンギア42Cによって正方向と逆方向の双方に回転駆動される駆動針43Cと、駆動針43Cの正回転時に駆動針43Cによって正回転し、駆動針43Cの逆回転時には回転されない従動針44Cと、駆動針43C及び従動針44Cを案内する案内溝部451C、及び目盛り452Cが形成された扇形状のパネル45Cと、を備えている。
パネル45Cに設けられた案内溝部451Cは、外縁に沿って円弧形状に形成されており、駆動針43Cの先端部や従動針44Cの先端部が嵌合される。本実施形態において、駆動針43Cの先端部には、使用者の手指によって把持されるハンドル46Cが設けられている。また、案内溝部451Cの内周縁には鋸刃形状の凹凸が形成されている。鋸刃形状の凹凸は、各針43C、44Cの正方向への移動は容易とし、各針43C、44Cの逆方向への移動には人による操作が必要とするために設けられている。
The display section 40C includes a rack gear 41C provided at the rear end of the first piece 21C (an end opposite to the insertion end) and a rear end of the second piece 22C (an end opposite to the insertion end). ), a drive needle 43C that is rotationally driven in both forward and reverse directions by the pinion gear 42C, and a drive needle 43C that is rotated in the forward direction by the drive needle 43C when the drive needle 43C rotates forward; It includes a driven needle 44C that is not rotated during reverse rotation, a guide groove 451C that guides the driving needle 43C and the driven needle 44C, and a fan-shaped panel 45C on which a scale 452C is formed.
The guide groove 451C provided in the panel 45C is formed in an arc shape along the outer edge, into which the tip of the drive needle 43C and the tip of the driven needle 44C are fitted. In this embodiment, a handle 46C that is gripped by the user's fingers is provided at the tip of the drive needle 43C. Additionally, saw blade-shaped unevenness is formed on the inner peripheral edge of the guide groove portion 451C. The saw blade-shaped unevenness is provided because it is easy to move each needle 43C, 44C in the forward direction, and human operation is required to move each needle 43C, 44C in the opposite direction.

第3実施形態に係る筋力表示装置1Cでは、骨盤底筋MSの収縮によって両片21C、22C間の間隔を狭める方向の外力Fが作用するとコイルバネ50Cが抗力を生成する。外力Fが抗力に勝ると両片21C、22C間の間隔が狭められ、ラックギア41Cの移動によってピニオンギア42Cが正方向に回転する。ピニオンギア42Cの回転に伴って駆動針43C、及び従動針44Cが正方向に回転する。そして、外力Fと抗力とが釣り合うと、駆動針43Cと従動針44Cの正方向への回転は停止する。
使用者が骨盤底筋MSを弛緩させると、コイルバネ50Cの復元力によって両片21C、22C間の間隔が拡げられ、ラックギア41Cの移動によってピニオンギア42Cが逆方向に回転する。ピニオンギア42Cの回転に伴い、駆動針43Cは逆方向に回転するが、従動針44Cは案内溝部451Cに嵌合して回転しない。
このため、従動針44Cの角度は、骨盤底筋MSの収縮によって挿入部20Cが受けた外力Fの値(骨盤底筋MSの筋力)を示す。
従って、使用者は、従動針44Cの角度に基づいて、骨盤底筋MSの筋力を知ることができる。
In the muscle strength display device 1C according to the third embodiment, the coil spring 50C generates a resistance force when an external force F is applied in a direction to narrow the distance between the two pieces 21C and 22C due to contraction of the pelvic floor muscles MS. When the external force F exceeds the drag force, the distance between the pieces 21C and 22C is narrowed, and the movement of the rack gear 41C causes the pinion gear 42C to rotate in the forward direction. As the pinion gear 42C rotates, the driving needle 43C and the driven needle 44C rotate in the forward direction. Then, when the external force F and the drag force are balanced, the driving needle 43C and the driven needle 44C stop rotating in the forward direction.
When the user relaxes the pelvic floor muscles MS, the restoring force of the coil spring 50C widens the gap between the two pieces 21C and 22C, and the movement of the rack gear 41C causes the pinion gear 42C to rotate in the opposite direction. As the pinion gear 42C rotates, the drive needle 43C rotates in the opposite direction, but the driven needle 44C fits into the guide groove 451C and does not rotate.
Therefore, the angle of the driven needle 44C indicates the value of the external force F (muscle strength of the pelvic floor muscles MS) that the insertion section 20C receives due to the contraction of the pelvic floor muscles MS.
Therefore, the user can know the muscle strength of the pelvic floor muscles MS based on the angle of the driven needle 44C.

<第3実施形態の変形例に係る筋力表示装置1D>
図14に示す変形例に係る筋力表示装置1Dは、指針式の表示部40Dを備えている点、及び挿入部20Dの第1片21Dと第2片22Dとの間に抗力生成部として機能するコイルバネ50Dを備えている点は、図13の筋力表示装置1Cと同様である。
変形例に係る筋力表示装置1Dでは、ラックギア41Dを第1片21Dの後端から側方に向けて設け、角柱形状の案内軸46Dをラックギア41Dと一体に、且つラックギア41Dの長手方向に沿って設け、案内軸46Dの側面には複数の係合凹所461Dを所定ピッチで設けている。本実施形態において、係合凹所461Dは浅い湾曲凹面である。
一方、第2片22Dの後端には案内軸46Dが挿通される角筒形状の案内筒部47Dと、ラックギア41Dの移動によって回転するピニオンギア42Dと、ピニオンギア42Dによって回転駆動される指針43Dと、目盛り452Dが形成された扇形状のパネル45Dと、が設けられている。
また、案内筒部47Dには、係合凹所461Dに嵌合自在な係合突起471Dが設けられている。本実施形態において、係合突起471Dは半球形状である。このため、係合突起471Dは、案内軸46Dの長手方向への移動に伴って、係合凹所461Dへの嵌合と離脱とを繰り返し行う。
<Muscle strength display device 1D according to a modification of the third embodiment>
The muscle strength display device 1D according to the modification shown in FIG. 14 includes a pointer-type display section 40D, and functions as a drag generation section between the first piece 21D and the second piece 22D of the insertion section 20D. It is the same as the muscle strength display device 1C in FIG. 13 in that it includes a coil spring 50D.
In the muscle strength display device 1D according to the modification, the rack gear 41D is provided laterally from the rear end of the first piece 21D, and the prismatic guide shaft 46D is integrally formed with the rack gear 41D and extends along the longitudinal direction of the rack gear 41D. A plurality of engagement recesses 461D are provided at a predetermined pitch on the side surface of the guide shaft 46D. In this embodiment, the engagement recess 461D is a shallow curved concave surface.
On the other hand, at the rear end of the second piece 22D, there is a rectangular guide tube portion 47D through which a guide shaft 46D is inserted, a pinion gear 42D that rotates as the rack gear 41D moves, and a pointer 43D that is rotationally driven by the pinion gear 42D. and a fan-shaped panel 45D on which a scale 452D is formed.
Further, the guide tube portion 47D is provided with an engagement protrusion 471D that can be freely fitted into the engagement recess 461D. In this embodiment, the engagement protrusion 471D has a hemispherical shape. Therefore, the engagement protrusion 471D repeatedly engages and disengages from the engagement recess 461D as the guide shaft 46D moves in the longitudinal direction.

変形例に係る筋力表示装置1Dでは、骨盤底筋MSの収縮によって両片21D、22D間の間隔を狭める方向の外力Fが作用するとコイルバネ50Dが抗力を生成する。また、係合突起471Dが係合凹所461Dに嵌合することによっても抗力を生成される。
外力Fが抗力に勝ると両片21D、22D間の間隔が狭められてラックギア41Dが移動し、係合突起471Dは係合凹所461Dから離れて隣の係合突起471Dに嵌まる。ラックギア41Dの移動によってピニオンギア42Dが正方向に回転し、指針43Dも正方向に回転する。そして、外力Fと抗力とが釣り合うと、指針43Dの正方向への回転は停止する。
In the muscle strength display device 1D according to the modified example, when an external force F is applied in a direction to narrow the distance between the pieces 21D and 22D due to contraction of the pelvic floor muscles MS, the coil spring 50D generates a resistance force. Further, a drag force is also generated by the engagement protrusion 471D fitting into the engagement recess 461D.
When the external force F overcomes the drag force, the distance between the pieces 21D and 22D is narrowed, the rack gear 41D moves, and the engagement protrusion 471D moves away from the engagement recess 461D and fits into the adjacent engagement protrusion 471D. As the rack gear 41D moves, the pinion gear 42D rotates in the forward direction, and the pointer 43D also rotates in the forward direction. Then, when the external force F and the drag force are balanced, the pointer 43D stops rotating in the forward direction.

使用者が骨盤底筋MSを弛緩させると、第1片21Dと第2片22Dにはコイルバネ50Dの復元力が作用するが、係合突起471Dが係合凹所461Dに嵌合しているため、第1片21Dと第2片22Dの間隔は狭められた状態を維持する。
このため、指針43Dの角度は、骨盤底筋MSの収縮によって挿入部20Cが受けた外力Fの値(骨盤底筋MSの筋力)を示す。
従って、使用者は、従動針44Cの角度に基づいて、骨盤底筋MSの筋力を知ることができる。
When the user relaxes the pelvic floor muscles MS, the restoring force of the coil spring 50D acts on the first piece 21D and the second piece 22D, but because the engagement protrusion 471D is fitted into the engagement recess 461D. , the distance between the first piece 21D and the second piece 22D remains narrow.
Therefore, the angle of the pointer 43D indicates the value of the external force F (muscle strength of the pelvic floor muscles MS) that the insertion portion 20C receives due to the contraction of the pelvic floor muscles MS.
Therefore, the user can know the muscle strength of the pelvic floor muscles MS based on the angle of the driven needle 44C.
