Description

本発明は、手指の動揺を抑制するための装着具に関する。 The present invention relates to a fitting for suppressing the shaking of fingers.

変形性指関節症は、加齢等により手指の関節の靭帯が伸びて、関節が左右に動揺することにより関節に炎症が起こり、痛みや腫れの症状が生じる疾患である。変形性関節症のうち、手指の第１関節（ＤＩＰ関節）に生じるものはヘバーデン結節と呼ばれ、手指の第２関節（ＰＩＰ関節）に生じるものはブシャール結節と呼ばれている。 Degenerative finger arthropathy is a disease in which the ligaments of the finger joints are stretched due to aging or the like, and the joints are shaken from side to side, causing inflammation of the joints and causing pain and swelling. Among osteoarthritis, those occurring in the first joint (DIP joint) of the fingers are called Heberden's node, and those occurring in the second joint (PIP joint) of the fingers are called Bouchard's node.

変形性関節症は、家事等で手指を使用する機会が多い中年から高齢の女性の発症率が高いことが知られている。変形性指関節症への処置方法としては、例えば、手指の関節にテーピングテープを巻き付けることにより関節の動揺を抑制する方法や、患者に治療剤（例えば、特許文献１を参照）を投与する方法などが提案されている。 It is known that osteoarthritis has a high incidence in middle-aged to elderly women who often use their fingers for housework. Examples of the treatment method for osteoarthritis of the fingers include a method of suppressing joint sway by wrapping a taping tape around the joints of the fingers, and a method of administering a therapeutic agent (see, for example, Patent Document 1) to a patient. Etc. have been proposed.

特開２０１６−２１６４５２号Japanese Unexamined Patent Publication No. 2016-216452

テーピングテープを使用した場合、簡易な作業で手指の関節の動揺を抑制することができる。しかしながら、テーピングテープが水等と触れて濡れると、患者が不快を感じるだけでなく、皮膚トラブルを起こす可能性がある。そのため、家事を行う女性等には不向きである。また、治療剤を投与する方法は、継続的な薬剤の投与が必要なうえ、患者個人毎の治療効果にもばらつきが生じ得る。 When taping tape is used, it is possible to suppress the sway of the finger joints with a simple operation. However, if the taping tape comes into contact with water or the like and gets wet, not only the patient feels uncomfortable, but also skin troubles may occur. Therefore, it is not suitable for women who do housework. In addition, the method of administering the therapeutic agent requires continuous administration of the drug, and the therapeutic effect of each individual patient may vary.

本発明は上記のような課題に基づいてなされたものであり、患者の手指に簡単に装着させることができ、かつ、手指の関節の動揺を抑制することができる装着具を提供することを目的とする。 The present invention has been made based on the above-mentioned problems, and an object of the present invention is to provide a fitting that can be easily attached to a patient's fingers and can suppress the sway of the finger joints. And.

本発明に係る装着具は、手指の関節の動揺を抑制するための装着具であって、前記手指の一部が配置される空間部と、前記空間部内への前記手指の挿入を可能にする第１挿入部と、前記空間部内からの前記手指の突出を可能にする第２挿入部と、前記空間部に配置された前記手指の少なくとも一部を手の甲側に露出させる開口部と、前記手指の屈曲動作を許容しつつ、前記手指の少なくとも一部を手の掌側で支持する支持部と、を有する。 The fitting according to the present invention is a fitting for suppressing the sway of the joints of the fingers, and enables the insertion of the fingers into the space portion where a part of the fingers is arranged and the space portion. A first insertion portion, a second insertion portion that allows the fingers to protrude from the space, an opening that exposes at least a part of the fingers arranged in the space to the back side of the hand, and the fingers. It has a support portion that supports at least a part of the fingers on the palm side of the hand while allowing the bending motion of the finger.

本発明によれば、使用者（患者）は、第１挿入部および第２挿入部に手指を挿通させる簡単な作業により、装着具を手指に装着させることができる。また、使用者が装着具を手指に装着すると、開口部により手指の手の甲側の一部が露出されるとともに、支持部により手指の手の掌側の一部が屈曲動作可能に支持される。そのため、使用者は、装着具を手指に装着した状態で手指を屈曲動作させる際、開口部を通じて手指の屈曲動作が制限されることを防止できる。さらに、使用者は、各挿入部に手指を挿入し、空間部内に手指の一部を配置することにより、手指が不用意に動揺することを抑制できる。 According to the present invention, the user (patient) can attach the fitting to the fingers by a simple operation of inserting the fingers into the first insertion portion and the second insertion portion. Further, when the user attaches the fitting to the fingers, a part of the back side of the hand of the finger is exposed by the opening, and a part of the palm side of the hand of the finger is supported by the support portion so as to be able to bend. Therefore, the user can prevent the bending motion of the fingers from being restricted through the opening when the fingers are flexed while the wearing tool is attached to the fingers. Further, the user can prevent the fingers from being inadvertently shaken by inserting the fingers into each insertion portion and arranging a part of the fingers in the space portion.

When outlined with reference to FIGS. 1 and 5, the fitting 100 has a space portion 105 in which a part of the user's finger F is arranged, and a first portion that enables insertion of the finger F into the space portion 105. An insertion portion 110, a second insertion portion 120 that allows the finger F to protrude from the space portion 105, and an opening 130 that exposes at least a part of the finger F arranged in the space portion 105 to the back side of the hand. It has a support portion 140 that supports at least a part of the finger F on the palm side of the hand while allowing the bending motion of the finger F.

支持部１４０は、図１、図３に示すように、手指Ｆの外周方向において開口部１３０が形成された位置と対向する位置（図３の上下方向で対向する位置）に形成されている。使用者は、図７、図８に示すように、装着具１００を患者の手指Ｆに装着した際、支持部１４０を、手指Ｆの掌側に位置する第２関節Ｊ２の関節線の少なくとも一部に沿わせるように配置することができる。 As shown in FIGS. 1 and 3, the support portion 140 is formed at a position facing the position where the opening 130 is formed (a position facing in the vertical direction in FIG. 3) in the outer peripheral direction of the finger F. As shown in FIGS. 7 and 8, when the attachment 100 is attached to the patient's finger F, the user attaches the support portion 140 to at least one of the joint lines of the second joint J2 located on the volar side of the finger F. It can be arranged along the part.

第１挿入部１１０は、図１、図２、図７に示すように、手指Ｆの側部側に配置される第１挟持部１１１と、手指Ｆの側部側に配置され、第１挟持部１１１との間で手指Ｆを挟み込む第２挟持部１１２と、第１挟持部１１１と第２挟持部１１２との間を繋ぐ中間部１１３と、を有する。 As shown in FIGS. 1, 2, and 7, the first insertion portion 110 is arranged on the side portion side of the finger F and the first sandwiching portion 111 arranged on the side portion side of the finger F, and is arranged on the side portion side of the finger F. It has a second sandwiching portion 112 that sandwiches the finger F between the portions 111, and an intermediate portion 113 that connects the first sandwiching portion 111 and the second sandwiching portion 112.

第１挿入部１１０は、第１挟持部１１１と第２挟持部１１２との間に区画された開口部１１０ａを有する。この開口部１１０ａは、使用者の手指Ｆを空間部１０５内に導入する入口部分を構成する（図５を参照）。 The first insertion portion 110 has an opening 110a partitioned between the first sandwiching portion 111 and the second sandwiching portion 112. The opening 110a constitutes an entrance portion for introducing the user's finger F into the space 105 (see FIG. 5).

第１挟持部１１１、第２挟持部１１２、および中間部１１３は、図４に示す正面視において、円弧形状を有する。 The first sandwiching portion 111, the second sandwiching portion 112, and the intermediate portion 113 have an arc shape in the front view shown in FIG.

第２挿入部１２０は、図１、図２に示すように、手指Ｆの側部側に配置される第１挟持部１２１と、手指Ｆの側部側に配置され、第１挟持部１２１との間で手指Ｆを挟み込む第２挟持部１２２と、第１挟持部１２１と第２挟持部１２２を繋ぐ中間部１２３と、を有する。 As shown in FIGS. 1 and 2, the second insertion portion 120 is arranged with the first holding portion 121 arranged on the side side of the finger F and the first holding portion 121 arranged on the side side of the finger F. It has a second sandwiching portion 122 that sandwiches the finger F between the two, and an intermediate portion 123 that connects the first sandwiching portion 121 and the second sandwiching portion 122.

第２挿入部１２０は、第１挿入部１１０と略同一の形状を有する。第２挿入部１２０は、第１挟持部１２１と第２挟持部１２２との間に区画された開口部１２０ａを有する。この開口部１２０ａは、使用者の手指Ｆを空間部１０５の外部へ突出させる出口部分を構成する（図５を参照）。 The second insertion portion 120 has substantially the same shape as the first insertion portion 110. The second insertion portion 120 has an opening 120a partitioned between the first sandwiching portion 121 and the second sandwiching portion 122. The opening 120a constitutes an outlet portion for projecting the user's finger F to the outside of the space portion 105 (see FIG. 5).

使用者は、図５、図７に示すように、第１挿入部１１０を介して空間部１０５内に手指Ｆの一部を挿入させ、さらに、第２挿入部１２０を介して空間部１０５内から手指Ｆの指先側の一部を突出させることにより、手指Ｆに装着具１００を装着させることができる。 As shown in FIGS. 5 and 7, the user inserts a part of the finger F into the space portion 105 via the first insertion portion 110, and further inserts a part of the finger F into the space portion 105 via the second insertion portion 120. By projecting a part of the fingertip side of the finger F from the finger F, the fitting 100 can be attached to the finger F.

第１挿入部１１０の第１挟持部１１１および第２挟持部１１２は、手指Ｆに装着具１００が装着されると、空間部１０５よりも手指Ｆの付け根側の位置で、手指Ｆを両側部側（図６の上下方向側）から挟み込む。また、第２挿入部１２０の第１挟持部１２１および第２挟持部１２２は、空間部１０５よりも手指Ｆの指先側の位置で、手指Ｆを両側部側から挟み込む。支持部１４０は、図７に示すように、手の掌側で手指Ｆを支持する。装着具１００は、上記のように手指Ｆに装着されると、第１挿入部１１０、第２挿入部１２０、および支持部１４０の三箇所で手指Ｆに対してしっかりと固定される。そのため、使用者は、装着具１００を手指Ｆに装着することで、手指Ｆが側方に動揺することを抑制できる。 When the attachment 100 is attached to the finger F, the first sandwiching portion 111 and the second sandwiching portion 112 of the first insertion portion 110 are positioned on the base side of the finger F with respect to the space portion 105, and the fingers F are placed on both sides. It is sandwiched from the side (vertical side in FIG. 6). Further, the first sandwiching portion 121 and the second sandwiching portion 122 of the second inserting portion 120 sandwich the finger F from both side portions at a position on the fingertip side of the finger F with respect to the space portion 105. As shown in FIG. 7, the support portion 140 supports the finger F on the palm side of the hand. When the fitting 100 is attached to the finger F as described above, the fitting 100 is firmly fixed to the finger F at three positions, the first insertion portion 110, the second insertion portion 120, and the support portion 140. Therefore, the user can prevent the finger F from shaking laterally by attaching the fitting 100 to the finger F.

図１、図３に示すように、第１挿入部１１０および第２挿入部１２０の各々は、開口部１３０側に配置された各上端１１５ａ、１２５ａから支持部１４０側に配置された各下端１１５ｂ、１２５ｂに向けて両者の間の距離が徐々に狭まるように傾斜している。 As shown in FIGS. 1 and 3, each of the first insertion portion 110 and the second insertion portion 120 has upper ends 115a and 125a arranged on the opening 130 side and lower ends 115b arranged on the support portion 140 side, respectively. , 125b is inclined so that the distance between the two gradually narrows.

より具体的には、図３に示す側面図において、第１挿入部１１０の第１挟持部１１１は、第１挿入部１１０の上端に相当する中間部１１３の上端１１５ａ側から第１挿入部１１０の下端１１５ｂ側に向けて、空間部１０５の中心位置Ｏへ徐々に近づくように傾斜している。また、第２挿入部１２０の第１挟持部１２１は、第２挿入部１２０の上端に相当する中間部１１３の上端１２５ａ側から第２挿入部１２０の下端１２５ｂ側に向けて、空間部１０５の中心位置Ｏへ徐々に近づくように傾斜している。そのため、第１挿入部１１０と第２挿入部１２０は、空間部１０５の中心位置Ｏを基準として、各下端１１５ｂ、１２５ｂ側から各上端１１５ａ、１２５ａ側に向けて略対称に延びるＶ字形状を呈している。 More specifically, in the side view shown in FIG. 3, the first insertion portion 111 of the first insertion portion 110 is the first insertion portion 110 from the upper end 115a side of the intermediate portion 113 corresponding to the upper end of the first insertion portion 110. It is inclined toward the lower end 115b side of the space portion 105 so as to gradually approach the center position O of the space portion 105. Further, the first holding portion 121 of the second insertion portion 120 is a space portion 105 from the upper end 125a side of the intermediate portion 113 corresponding to the upper end of the second insertion portion 120 toward the lower end 125b side of the second insertion portion 120. It is inclined so as to gradually approach the central position O. Therefore, the first insertion portion 110 and the second insertion portion 120 have a V-shape extending substantially symmetrically from the lower end 115b and 125b sides to the upper end 115a and 125a sides with reference to the center position O of the space portion 105. It is presented.

支持部１４０は、図１、図２に示すように、第１挿入部１１０の第１挟持部１１１および第２挿入部１２０の第１挟持部１２１の接続点付近と、第１挿入部１１０の第２挟持部１１２および第２挿入部１２０の第２挟持部１２２の接続点付近の二箇所に形成されている。一組の支持部１４０の間には隙間ｇが形成されている。 As shown in FIGS. 1 and 2, the support portion 140 is provided in the vicinity of the connection point between the first sandwiching portion 111 of the first insertion portion 110 and the first sandwiching portion 121 of the second insertion portion 120, and the first insertion portion 110. It is formed at two locations near the connection point of the second sandwiching portion 122 of the second sandwiching portion 112 and the second inserting portion 120. A gap g is formed between the set of support portions 140.

図７、図８に示すように、使用者は、装着具１００を手指Ｆに装着した際、開口部１３０を第２関節Ｊ２に配置することができる。使用者は、開口部１３０により、第２関節Ｊ２付近の一部を手の甲側に露出させることができる。また、使用者は、使用者の手の掌側に位置する第２関節Ｊ２の関節線（近位指節間関節線）に支持部１４０を配置することができる。手指Ｆの関節線は、図８に示すように、手指Ｆを屈曲動作させた際、手の掌側から手の甲側に向けて窪んだ形状となる。第２関節Ｊ２の関節線に配置された支持部１４０は、手の掌側で手指Ｆを支持する。 As shown in FIGS. 7 and 8, the user can arrange the opening 130 at the second joint J2 when the wearing tool 100 is attached to the finger F. The user can expose a part of the vicinity of the second joint J2 to the back side of the hand by the opening 130. In addition, the user can arrange the support portion 140 at the joint line (proximal interphalangeal joint line) of the second joint J2 located on the palm side of the user's hand. As shown in FIG. 8, the joint line of the finger F has a shape that is recessed from the palm side of the hand to the back side of the hand when the finger F is flexed. The support portion 140 arranged on the joint line of the second joint J2 supports the finger F on the palm side of the hand.

上記のように、手指Ｆの第２関節Ｊ２付近の一部は、開口部１３０により手の甲側に露出される。そのため、使用者が手指Ｆの屈曲動作を行う際、手指Ｆの第２関節Ｊ２付近の部分は、装着具１００からの拘束力を受けない。また、手指Ｆの第２関節Ｊ２の手の掌側では、第２関節Ｊ２の関節線の一部（手指Ｆの側部付近の一部）が支持部１４０により支持されるとともに、支持部１４０の間に形成された隙間ｇにより第２関節Ｊ２の関節線の一部が支持されていない状態となる。このように第２関節Ｊ２の関節線に支持部１４０および隙間ｇが配置されることにより、第２関節Ｊ２を基点にして手指Ｆを屈曲動作させる際、関節線よりも指先側に位置する手指Ｆの腹部分および関節線よりも指の付け根側に位置する手指Ｆの腹部分に対して支持部１４０が干渉することを防止できる。したがって、使用者は、支持部１４０により手指Ｆを掌側から支持させつつ、第２関節Ｊ２を基点にして手指Ｆを屈曲動作させることが可能となる。 As described above, a part of the finger F near the second joint J2 is exposed to the back side of the hand by the opening 130. Therefore, when the user performs the bending motion of the finger F, the portion of the finger F near the second joint J2 is not subject to the binding force from the fitting 100. Further, on the palm side of the second joint J2 of the finger F, a part of the joint line of the second joint J2 (a part near the side of the finger F) is supported by the support portion 140, and the support portion 140 A part of the joint line of the second joint J2 is not supported by the gap g formed between the two joints. By arranging the support portion 140 and the gap g at the joint line of the second joint J2 in this way, the fingers located on the fingertip side of the joint line when the finger F is flexed with the second joint J2 as the base point. It is possible to prevent the support portion 140 from interfering with the abdominal portion of the F and the abdominal portion of the finger F located closer to the base of the finger than the joint line. Therefore, the user can bend the finger F with the second joint J2 as the base point while supporting the finger F from the palm side by the support portion 140.

装着具１００は、図５、図６に示すように、空間部１０５を挿通するように配置された手指Ｆを、第１挿入部１１０および第２挿入部１２０により手指Ｆの両側部側で挟み込みつつ、支持部１４０により手指Ｆを掌側から支持して固定する。第１挿入部１１０、第２挿入部１２０、支持部１４０の各々は、手指Ｆが第２関節Ｊ２を基点にして屈曲動作する前後の状態、および、屈曲動作している間、手指Ｆに対する装着具１００の固定を維持する。これにより、装着具１００は、手指Ｆの屈曲動作を許容しつつ、手指Ｆが側方に動揺することを抑制することができ、手指Ｆの動揺に伴って変形性指関節症由来の痛み等が生じることを防止できる。また、装着具１００は、テーピングテープのような接着部材を利用して使用者の皮膚に対して固定するように構成されていないため、使用時に装着具１００が濡れたとしても、患者は不快を感じず、さらに皮膚トラブルを生じる可能性が低い。 As shown in FIGS. 5 and 6, the fitting 100 sandwiches the finger F arranged so as to insert the space portion 105 between the first insertion portion 110 and the second insertion portion 120 on both side surfaces of the finger F. At the same time, the finger F is supported and fixed from the palm side by the support portion 140. Each of the first insertion portion 110, the second insertion portion 120, and the support portion 140 is attached to the finger F before and after the finger F flexes with respect to the second joint J2, and during the flexion operation. Keep the tool 100 fixed. As a result, the fitting 100 can suppress the lateral sway of the finger F while allowing the bending motion of the finger F, and the pain caused by osteoarthritis of the finger F and the like due to the sway of the finger F can be suppressed. Can be prevented from occurring. Further, since the fitting 100 is not configured to be fixed to the user's skin by using an adhesive member such as a taping tape, even if the fitting 100 gets wet during use, the patient feels uncomfortable. It does not feel and is less likely to cause skin problems.

図３を参照して、第１挿入部１１０と第２挿入部１２０との間に形成される開き角度θ１は、例えば、４０°〜８０°で形成することができる。開き角度θ１を上記のような角度に設定することにより、開口部１３０の挿入方向（図２の左右方向）に沿う大きさを、第２関節Ｊ２の屈曲動作を許容する適切な大きさに形成することができる。また、開口部１３０の挿入方向に沿う大きさが過剰に大きく形成されることによって第２関節Ｊ２付近で手指Ｆが不用意に側方に動揺してしまうといった問題が生じることも防止できる。 With reference to FIG. 3, the opening angle θ1 formed between the first insertion portion 110 and the second insertion portion 120 can be formed, for example, from 40 ° to 80 °. By setting the opening angle θ1 to the above angle, the size along the insertion direction (left-right direction in FIG. 2) of the opening 130 is formed to an appropriate size that allows the bending motion of the second joint J2. can do. Further, it is possible to prevent a problem that the finger F is inadvertently swayed laterally in the vicinity of the second joint J2 due to the excessively large size of the opening 130 along the insertion direction.

第１挿入部１１０および第２挿入部１２０を形成する材料の曲げ荷重は、例えば、３０Ｎ〜８０Ｎで形成することができる。これは下記の理由による。なお、曲げ荷重の測定は、第１挿入部１１０を切断して、各々を略直線状に伸ばした状態でＪＩＳＫ７１７１に準拠した３点曲げ試験により得られる計測結果である。第２挿入部１２０の曲げ荷重についても同様である。 The bending load of the material forming the first insertion portion 110 and the second insertion portion 120 can be formed, for example, from 30N to 80N. This is due to the following reasons. The bending load is measured by a three-point bending test based on JIS K7171 in a state where the first insertion portion 110 is cut and each is stretched substantially linearly. The same applies to the bending load of the second insertion portion 120.

装着具１００は、使用者が手指Ｆを屈曲動作させた際に屈曲動作に応じて容易に変形してしまうと、使用者の手指Ｆの動揺を抑制する効果が低減してしまう。一方で、使用者の手指Ｆが腫れる等して、手指Ｆの外形が部分的に大きくなったり、腫れが引いて手指Ｆの外形が部分的に小さくなったりした場合においても、装着具１００を別のサイズの物に変更することなく、少なくとも同一の使用者に対しては使い回し可能であることが好ましい。上記のように、装着具１００の骨格部分を構成する第１挿入部１１０および第２挿入部１２０を形成する材料の曲げ荷重を３０〜８０Ｎで形成した場合、手指Ｆの屈曲動作に伴って装着具１００が容易に変形することを防止できる。また、上記範囲の曲げ荷重の数値を採用することにより、使用者がある程度の力を込めて第１挿入部１１０および第２挿入部１２０を押し広げたり、縮めたりすることにより、手指Ｆの腫れの程度等に合わせて装着具１００を手指Ｆに装着させることが可能な形状に変形させることができる。 If the wearer 100 is easily deformed in response to the bending motion when the user bends the finger F, the effect of suppressing the shaking of the finger F of the user is reduced. On the other hand, even when the outer shape of the finger F is partially enlarged due to swelling of the user's finger F or the outer shape of the finger F is partially reduced due to the swelling, the fitting 100 is used. It is preferable that it can be reused for at least the same user without changing to a different size. As described above, when the bending load of the material forming the first insertion portion 110 and the second insertion portion 120 constituting the skeleton portion of the attachment 100 is formed to be 30 to 80 N, the attachment is performed with the bending operation of the finger F. It is possible to prevent the tool 100 from being easily deformed. Further, by adopting the numerical value of the bending load in the above range, the user pushes the first insertion portion 110 and the second insertion portion 120 with a certain amount of force to expand or contract the swelling of the finger F. The fitting 100 can be deformed into a shape that can be attached to the finger F according to the degree of the above.

なお、装着具１００には開口部１３０および隙間ｇが形成されているため、当該装着具１００を手指Ｆに装着した際、手指Ｆは装着具１００によって全周が覆われない。そのため、使用者は、各挿入部１１０、１２０の各挟持部１１１、１１２、１２１、１２２を手指で把持するなどして力を込めて、各挟持部１１１、１１２、１２１、１２２の距離を広げるように押し広げたり、縮めたりすることにより、装着具１００の外形を比較的容易に変形させることができる。 Since the fitting 100 is formed with an opening 130 and a gap g, the entire circumference of the fitting 100 is not covered by the fitting 100 when the fitting 100 is attached to the finger F. Therefore, the user increases the distance between the holding portions 111, 112, 121, 122 by grasping the holding portions 111, 112, 121, 122 of the insertion portions 110, 120 with his / her fingers. By expanding and contracting in this way, the outer shape of the fitting 100 can be deformed relatively easily.

第１挿入部１１０、第２挿入部１２０、および支持部１４０の各々は、例えば、ステンレス、黄銅、リン青銅、金、および銀の少なくとも一つからなる線状体により一体的に構成することができる。 Each of the first insertion portion 110, the second insertion portion 120, and the support portion 140 may be integrally formed of, for example, a linear body composed of at least one of stainless steel, brass, phosphor bronze, gold, and silver. can.

上記の線状体とは、例えば、断面積が１０ｍｍ２以下のものと定義することができる。線状体の具体的な断面形状は特に限定されないが、例えば、円形、楕円形、正方形、長方形等を挙げることができる。なお、線状体の断面形状が円形である場合、断面の直径は、例えば、７ｍｍ〜３０ｍｍとすることができる。 The above-mentioned linear body can be defined as, for example, one having a cross-sectional area of 10 mm2 or less. The specific cross-sectional shape of the linear body is not particularly limited, and examples thereof include a circle, an ellipse, a square, and a rectangle. When the cross-sectional shape of the linear body is circular, the diameter of the cross section can be, for example, 7 mm to 30 mm.

装着具１００は、第１挿入部１１０、第２挿入部１２０、および支持部１４０の各々がステンレス、黄銅、リン青銅、金、および銀の少なくとも一つの材料で構成されている場合、前述した曲げ荷重が３０Ｎ〜８０Ｎであり、かつ、特定の形状を付加することができる加工性に優れたものとなる。装着具１００の製造方法は特に限定されないが、構成材料としてステンレス、黄銅、リン青銅、金、銀が用いられる場合、例えば、鋳造、ワイヤーフォーミングを採用することができる。 In the fitting 100, when each of the first insertion portion 110, the second insertion portion 120, and the support portion 140 is made of at least one material of stainless steel, brass, phosphor bronze, gold, and silver, the above-mentioned bending is performed. The load is 30N to 80N, and the workability is excellent so that a specific shape can be added. The manufacturing method of the fitting 100 is not particularly limited, but when stainless steel, brass, phosphor bronze, gold, or silver is used as the constituent material, for example, casting or wire forming can be adopted.

なお、装着具１００は、当該装着具１００の各部で断名形状や構成材料が異なっていてもよい。また、装着具１００は、例示した金属以外の金属で構成してもよいし、樹脂材料等で構成してもよい。また、装着具１００の製造方法は鋳造以外を採用することもでき、例えば、構成材料の材質に応じて射出成形等を採用することができる。 The mounting tool 100 may have a different shape and constituent material for each part of the mounting tool 100. Further, the fitting 100 may be made of a metal other than the illustrated metal, or may be made of a resin material or the like. Further, the mounting method 100 may be manufactured by a method other than casting. For example, injection molding or the like can be adopted depending on the material of the constituent material.

（作用効果）
以上のように、本実施形態に係る装着具１００は、手指Ｆの動揺を抑制するための装着具である。装着具１００は、手指Ｆの一部が配置される空間部１０５と、空間部１０５内への手指Ｆの挿入を可能にする第１挿入部１１０と、空間部１０５内からの手指Ｆの突出を可能にする第２挿入部１２０と、空間部１０５に配置された手指Ｆの少なくとも一部を手の甲側に露出させる開口部１３０と、手指Ｆの屈曲動作を許容しつつ、手指Ｆの少なくとも一部を手の掌側で支持する支持部１４０と、を有する。(Action effect)
As described above, the fitting 100 according to the present embodiment is a fitting for suppressing the shaking of the finger F. The fitting 100 includes a space portion 105 in which a part of the finger F is arranged, a first insertion portion 110 that enables insertion of the finger F into the space portion 105, and a protrusion of the finger F from the inside of the space portion 105. The second insertion portion 120, the opening 130 that exposes at least a part of the finger F arranged in the space portion 105 to the back side of the hand, and at least one of the finger F while allowing the bending motion of the finger F. It has a support portion 140 that supports the portion on the palm side of the hand.

上記のように構成された装着具１００によれば、使用者は、第１挿入部１１０および第２挿入部１２０に手指Ｆを挿通させる簡単な作業により、装着具１００を手指Ｆに装着させることができる。また、使用者が装着具１００を手指Ｆに装着すると、開口部１３０により手指Ｆの手の甲側の一部が露出されるとともに、支持部１４０により手指Ｆの手の掌側の一部が屈曲動作可能に支持される。使用者は、装着具１００を手指Ｆに装着した状態で手指Ｆを屈曲動作させる際、開口部１３０を通じて手指Ｆの屈曲動作が制限されることを防止できる。また、使用者は、各挿入部１１０、１２０に手指Ｆを挿入し、空間部１０５内に手指Ｆの一部を配置することにより、手指Ｆが不用意に動揺することを抑制できる。 According to the fitting 100 configured as described above, the user attaches the fitting 100 to the finger F by a simple operation of inserting the finger F into the first insertion portion 110 and the second insertion portion 120. Can be done. Further, when the user attaches the fitting 100 to the finger F, the opening 130 exposes a part of the back side of the hand F, and the support 140 bends a part of the palm side of the hand F. Be supported as much as possible. When the user bends the finger F with the fitting 100 attached to the finger F, the user can prevent the bending motion of the finger F from being restricted through the opening 130. Further, the user can prevent the finger F from being inadvertently shaken by inserting the finger F into the insertion portions 110 and 120 and arranging a part of the finger F in the space portion 105.

また、支持部１４０は、手指Ｆの外周方向において開口部１３０が形成された位置と対向する位置に形成されており、かつ、手指Ｆの関節の関節線の少なくとも一部を支持可能に構成されている。そのため、使用者は、第２関節Ｊ２を基点にして手指Ｆを屈曲動作させる際、第２関節Ｊ２の関節線よりも指先側に位置する手指Ｆの腹部分および第２関節Ｊ２の関節線よりも指の付け根側に位置する手指Ｆの腹部分に対して支持部１４０が干渉することを防止できる。したがって、使用者は、支持部１４０により手指Ｆを掌側から支持させつつ、第２関節Ｊ２を基点にして手指Ｆを円滑に屈曲動作させることができる。 Further, the support portion 140 is formed at a position facing the position where the opening 130 is formed in the outer peripheral direction of the finger F, and is configured to be able to support at least a part of the joint line of the joint of the finger F. ing. Therefore, when the user flexes the finger F with the second joint J2 as the base point, the user uses the abdominal portion of the finger F and the joint line of the second joint J2 located closer to the fingertip side than the joint line of the second joint J2. It is possible to prevent the support portion 140 from interfering with the abdominal portion of the finger F located on the base side of the finger. Therefore, the user can smoothly bend the finger F with the second joint J2 as the base point while supporting the finger F from the palm side by the support portion 140.

また、第１挿入部１１０および第２挿入部１２０の各々は、手指Ｆの側部側に配置される第１挟持部１１１、１２１と、手指Ｆの側部側に配置され、各第１挟持部１１１、１２１との間で手指Ｆを挟み込む第２挟持部１１２、１２２と、を有する。そのため、装着具１００は、第１挿入部１１０および第２挿入部１２０が手指Ｆを両側部側で挟み込むことにより、手指Ｆをしっかと固定することができ、手指Ｆが側方に動揺することを効果的に抑制することができる。 Further, each of the first insertion portion 110 and the second insertion portion 120 is arranged on the side portion side of the finger F and the first sandwiching portions 111 and 121 arranged on the side portion side of the finger F, respectively. It has second holding portions 112 and 122 that sandwich the finger F between the portions 111 and 121. Therefore, in the fitting 100, the first insertion portion 110 and the second insertion portion 120 sandwich the finger F on both side surfaces, so that the finger F can be firmly fixed and the finger F is shaken laterally. It can be effectively suppressed.

また、第１挿入部１１０および第２挿入部１２０の各々は、開口部１３０側に配置された各上端１１５ａ、１２５ａから支持部１４０側に配置された各下端１１５ｂ、１２５ｂに向けて両者の間の距離が徐々に狭まるように傾斜している。そのため、装着具１００は、手指Ｆの第２関節Ｊ２の関節線で支持部１４０により手指Ｆを支持しつつ、支持部１４０の支持点を基点にして手指Ｆが開口部１３０側に凸状に屈曲動作することを許容する。したがって、使用者は、支持部１４０により手指Ｆを手の掌側でしっかりと支持させつつ、手指Ｆを容易に屈曲動作させることができる。 Further, each of the first insertion portion 110 and the second insertion portion 120 is between the upper ends 115a and 125a arranged on the opening 130 side toward the lower ends 115b and 125b arranged on the support portion 140 side. It is inclined so that the distance of is gradually narrowed. Therefore, in the fitting 100, the finger F is supported by the support portion 140 at the joint line of the second joint J2 of the finger F, and the finger F is convex toward the opening 130 with the support point of the support portion 140 as a base point. Allows bending motion. Therefore, the user can easily bend the finger F while firmly supporting the finger F on the palm side of the hand by the support portion 140.

また、第１挿入部１１０と第２挿入部１２０との間に形成される開き角度は４０°〜８０°である。そのため、挿入方向（矢印Ｘ１−Ｘ２方向）に沿う開口部１３０の大きさを、第２関節Ｊ２の屈曲動作を許容する適切な大きさに形成することができる。また、開口部１３０の上記大きさが過剰に大きく形成されることにより、第２関節Ｊ２付近で手指Ｆが不用意に側方に動揺してしまうといった問題が生じることを防止できる。 The opening angle formed between the first insertion portion 110 and the second insertion portion 120 is 40 ° to 80 °. Therefore, the size of the opening 130 along the insertion direction (arrows X1-X2 direction) can be formed to an appropriate size that allows the bending motion of the second joint J2. Further, when the size of the opening 130 is formed excessively large, it is possible to prevent a problem that the finger F is inadvertently swayed laterally in the vicinity of the second joint J2.

また、第１挿入部１１０および第２挿入部１２０を形成する材料の曲げ荷重は３０Ｎ〜８０Ｎである。そのため、手指Ｆの屈曲動作に伴って装着具１００が容易に変形することを防止でき、かつ、使用者が力を込めて操作することにより、手指Ｆの腫れの程度等に合わせて、第１挿入部１１０および第２挿入部１２０の形状を変形させることができる。 The bending load of the material forming the first insertion portion 110 and the second insertion portion 120 is 30N to 80N. Therefore, it is possible to prevent the fitting 100 from being easily deformed due to the bending motion of the finger F, and by the user operating with force, the first method is adjusted according to the degree of swelling of the finger F and the like. The shapes of the insertion portion 110 and the second insertion portion 120 can be deformed.

また、第１挿入部１１０、第２挿入部１２０、および支持部１４０の各々は、ステンレス、黄銅、リン青銅、金、および銀の少なくとも一つからなる線状体により一体的に構成されている。装着具１００は、第１挿入部１１０、第２挿入部１２０、および支持部１４０の各々が錫または錫合金で構成されることにより、前述した曲げ荷重３０Ｎ〜８０Ｎを有し、かつ、装着具１００に特定の形状を付加することを可能にする加工性に優れたものとなる。また、装着具１００は、第１挿入部１１０、第２挿入部１２０、および支持部１４０の各々が線状体により構成されることにより、美観に優れた意匠性を備えたものとなる。 Further, each of the first insertion portion 110, the second insertion portion 120, and the support portion 140 is integrally formed of a linear body composed of at least one of stainless steel, brass, phosphor bronze, gold, and silver. .. The fitting 100 has the above-mentioned bending load of 30N to 80N because the first insertion portion 110, the second insertion portion 120, and the support portion 140 are each made of tin or a tin alloy, and the fitting It has excellent workability that makes it possible to add a specific shape to 100. Further, the fitting 100 is provided with an aesthetically pleasing design because each of the first insertion portion 110, the second insertion portion 120, and the support portion 140 is formed of a linear body.

Each of the second holding portions 212 and 222 has substantially the same shape as the above-mentioned first holding portions 211 and 221.

第１挿入部２１０、第２挿入部２２０、および支持部２４０の各々は、例えば、ステンレス、黄銅、リン青銅、金、および銀の少なくとも一つからなる線状体により一体的に構成することができる。また、上記線状体を形成する材料の曲げ荷重（ＪＩＳＫ７１７１に準拠）は、例えば、３０Ｎ〜８０Ｎで形成することができる。 Each of the first insertion portion 210, the second insertion portion 220, and the support portion 240 may be integrally formed of, for example, a linear body composed of at least one of stainless steel, brass, phosphor bronze, gold, and silver. can. Further, the bending load of the material forming the linear body (according to JISK7171) can be formed, for example, from 30N to 80N.

使用者は、図１３、図１４に示すように、第１挿入部２１０を介して空間部２０５内に手指Ｆの一部を挿入させ、さらに、第２挿入部２２０を介して空間部２０５内から手指Ｆの指先側の一部を突出させることにより、手指Ｆに装着具２００を装着させることができる。 As shown in FIGS. 13 and 14, the user inserts a part of the finger F into the space portion 205 via the first insertion portion 210, and further inserts a part of the finger F into the space portion 205 via the second insertion portion 220. By projecting a part of the fingertip side of the finger F from the finger F, the fitting 200 can be attached to the finger F.

第１挿入部２１０の第１挟持部２１１および第２挟持部２１２は、手指Ｆに装着具２００が装着されると、空間部２０５よりも手指Ｆの付け根側の位置で、手指Ｆを両側部側（図１０の左右方向側）から挟み込む。また、第２挿入部２２０の第１挟持部２２１および第２挟持部２２２は、空間部２０５よりも手指Ｆの指先側の位置で、手指Ｆを両側部側から挟み込む。支持部１４０は、図１４に示すように、手の掌側で手指Ｆを支持する。装着具２００は、上記のように手指Ｆに装着されると、第１挿入部２１０、第２挿入部２２０、および支持部２４０の三箇所で手指Ｆに対してしっかりと固定される。そのため、使用者は、装着具２００を手指Ｆに装着することで、手指Ｆが側方に動揺することを抑制できる。 When the fitting 200 is attached to the finger F, the first sandwiching portion 211 and the second sandwiching portion 212 of the first insertion portion 210 are positioned on the base side of the finger F with respect to the space portion 205, and the fingers F are placed on both sides. It is sandwiched from the side (left-right direction side in FIG. 10). Further, the first sandwiching portion 221 and the second sandwiching portion 222 of the second inserting portion 220 sandwich the finger F from both side portions at a position on the fingertip side of the finger F with respect to the space portion 205. As shown in FIG. 14, the support portion 140 supports the finger F on the palm side of the hand. When the fitting 200 is attached to the finger F as described above, the fitting 200 is firmly fixed to the finger F at three positions, the first insertion portion 210, the second insertion portion 220, and the support portion 240. Therefore, the user can prevent the finger F from shaking laterally by attaching the fitting 200 to the finger F.

使用者が手指Ｆに装着具２００を装着させると、図１３に示すように、手指Ｆの第２関節Ｊ２は開口部１３０により手の甲側に露出される。そのため、使用者が手指Ｆの屈曲動作を行う際、手指Ｆの第２関節Ｊ２付近の部分は、手の甲側では装着具２００からの拘束力を受けない。また、手指Ｆの第２関節Ｊ２の手の掌側では、第２関節Ｊ２の関節線が支持部２４０により支持される。このように第２関節Ｊ２の関節線に沿って支持部２４０が配置されることにより、第２関節Ｊ２を基点にして手指Ｆを屈曲動作させる際、第２関節Ｊ２の関節線よりも指先側に位置する手指Ｆの腹部分および第２関節Ｊ２の関節線よりも指の付け根側に位置する手指Ｆの腹部分に対して支持部２４０が干渉することを防止できる。したがって、使用者は、支持部２４０により手指Ｆを掌側から支持させつつ、第２関節Ｊ２を基点にして手指Ｆを円滑に屈曲動作させることが可能となる。 When the user attaches the fitting 200 to the finger F, as shown in FIG. 13, the second joint J2 of the finger F is exposed to the back side of the hand by the opening 130. Therefore, when the user bends the finger F, the portion of the finger F near the second joint J2 is not bound by the fitting 200 on the back side of the hand. Further, on the palm side of the second joint J2 of the finger F, the joint line of the second joint J2 is supported by the support portion 240. By arranging the support portion 240 along the joint line of the second joint J2 in this way, when the finger F is flexed with the second joint J2 as the base point, the fingertip side of the joint line of the second joint J2. It is possible to prevent the support portion 240 from interfering with the abdominal portion of the finger F located at the position of the finger F and the abdominal portion of the finger F located on the base side of the finger with respect to the joint line of the second joint J2. Therefore, the user can smoothly bend the finger F with the second joint J2 as the base point while supporting the finger F from the palm side by the support portion 240.

また、第１挿入部２１０、第２挿入部２２０、および支持部２４０の各々は、手指Ｆが第２関節Ｊ２で屈曲動作する前後の状態、および、屈曲動作している間、手指Ｆに対する装着具２００の固定を維持する。そのため、装着具２００は、手指Ｆの屈曲動作を許容しつつ、手指Ｆが側方に動揺することを抑制できる。 Further, each of the first insertion portion 210, the second insertion portion 220, and the support portion 240 is attached to the finger F before and after the finger F flexes at the second joint J2, and during the flexion operation. Keep the tool 200 fixed. Therefore, the fitting 200 can suppress the finger F from swinging laterally while allowing the bending motion of the finger F.

また、本実施形態に係る装着具２００は、第１挿入部２１０が備える各挟持部２１１、２１２および第２挿入部２２０が備える各挟持部２２１、２２２が図１２に示すように面方向に広がりを持った形状で形成されている。そのため、装着具２００を使用者の手指Ｆに装着した際、各挿入部２１０、２２０は、手指Ｆの両側部の広い範囲に亘って手指Ｆと接触する。したがって、装着具２００は、使用者の手指Ｆが側方に動揺することをより効果的に抑制できる。 Further, in the fitting 200 according to the present embodiment, the holding portions 211 and 212 included in the first insertion portion 210 and the holding portions 221 and 222 included in the second insertion portion 220 spread in the plane direction as shown in FIG. It is formed in a shape with. Therefore, when the wearing tool 200 is attached to the user's finger F, the insertion portions 210 and 220 come into contact with the finger F over a wide range on both sides of the finger F. Therefore, the fitting 200 can more effectively suppress the user's finger F from being shaken laterally.

次に、図１７、図１８を参照して、本発明の第３実施形態に係る装着具３００を説明する。図１７は、装着具３００の概観斜視図であり、図１８は、装着具３００の使用例を説明するための図である。前述した第１、第２実施形態において説明した内容等は適宜省略する。(Third Embodiment)
Next, the fitting 300 according to the third embodiment of the present invention will be described with reference to FIGS. 17 and 18. FIG. 17 is an overview perspective view of the fitting 300, and FIG. 18 is a diagram for explaining a usage example of the fitting 300. The contents and the like described in the first and second embodiments described above will be omitted as appropriate.

図１７、図１８に示すように、装着具３００は、概説すると、使用者の手指Ｆの一部が配置される空間部３０５と、空間部３０５内への手指Ｆの挿入を可能にする第１挿入部３１０と、空間部３０５内からの手指Ｆの突出を可能にする第２挿入部３２０と、空間部３０５に配置された手指Ｆの少なくとも一部を手の甲側に露出させる開口部３３０と、手指Ｆの屈曲動作を許容しつつ、手指Ｆの少なくとも一部を手の掌側で支持する支持部３４０と、を有する。 As shown in FIGS. 17 and 18, the fitting 300 generally allows the user's finger F to be inserted into the space portion 305 in which a part of the user's finger F is arranged and the space portion 305. 1 Insertion portion 310, a second insertion portion 320 that allows the finger F to protrude from the space portion 305, and an opening 330 that exposes at least a part of the finger F arranged in the space portion 305 to the back side of the hand. It has a support portion 340 that supports at least a part of the finger F on the palm side of the hand while allowing the bending motion of the finger F.

装着具３００は、連続した一つの線状体に所定の形状を付加することで構成されている。 The fitting 300 is configured by adding a predetermined shape to one continuous linear body.

具体的には、第１挿入部３１０および第２挿入部３２０は、手指Ｆの外周に沿うように湾曲した形状を線状体に付加した部分で構成されている。支持部３４０は、第１挿入部３１０のうち手指Ｆの掌側に配置される湾曲した部分と、第２挿入部３２０のうち手指Ｆの掌側に配置される湾曲した部分とで構成されている。 Specifically, the first insertion portion 310 and the second insertion portion 320 are formed by adding a curved shape to the linear body along the outer circumference of the finger F. The support portion 340 is composed of a curved portion of the first insertion portion 310 arranged on the palm side of the finger F and a curved portion of the second insertion portion 320 arranged on the palm side of the finger F. There is.

第１挿入部３１０と第２挿入部３２０との間には両者の間を繋ぐ中間部３６０が延在している。中間部３６０は、手指Ｆの外周に沿って螺旋の一部を描くように湾曲した形状で形成されている。 An intermediate portion 360 connecting the first insertion portion 310 and the second insertion portion 320 extends between the first insertion portion 310 and the second insertion portion 320. The intermediate portion 360 is formed in a curved shape so as to draw a part of a spiral along the outer circumference of the finger F.

空間部３０５は、第１挿入部３１０と第２挿入部３２０の間に区画されている。開口部３３０は、空間部３０５の上方側に形成されている。 The space portion 305 is partitioned between the first insertion portion 310 and the second insertion portion 320. The opening 330 is formed on the upper side of the space 305.

第１挿入部３１０、第２挿入部３２０、支持部３４０、および中間部３６０の各々は、例えば、ステンレス、黄銅、リン青銅、金、および銀の少なくとも一つからなる線状体により一体的に構成することができる。また、上記線状体を形成する材料の曲げ荷重（ＪＩＳＫ７１７１に準拠）は、例えば、３０Ｎ〜８０Ｎで形成することができる。 Each of the first insertion portion 310, the second insertion portion 320, the support portion 340, and the intermediate portion 360 is integrally formed of, for example, a linear body consisting of at least one of stainless steel, brass, phosphor bronze, gold, and silver. Can be configured. Further, the bending load of the material forming the linear body (according to JISK7171) can be formed, for example, from 30N to 80N.

支持部３４０は、手指Ｆの外周方向において開口部３３０が形成された位置と対向する位置に形成されている。支持部３４０は、図１８に示すように、装着具３００を患者の手指Ｆに装着した際、手指Ｆの第２関節Ｊ２を間に挟んで、指先側および指の付け根側に配置することができる。 The support portion 340 is formed at a position facing the position where the opening 330 is formed in the outer peripheral direction of the finger F. As shown in FIG. 18, when the attachment 300 is attached to the finger F of the patient, the support portion 340 may be arranged on the fingertip side and the base side of the finger with the second joint J2 of the finger F sandwiched between them. can.

図１８に示すように、使用者が手指Ｆに装着具３００を装着すると、手指Ｆの第２関節Ｊ２の手の甲側の部分は、開口部３３０により外部に露出される。そのため、使用者が手指Ｆの屈曲動作を行う際、手指Ｆの第２関節Ｊ２付近の部分は、手の甲側では装着具２００からの拘束力を受けない。 As shown in FIG. 18, when the user attaches the fitting 300 to the finger F, the portion of the second joint J2 of the finger F on the back side of the hand is exposed to the outside by the opening 330. Therefore, when the user bends the finger F, the portion of the finger F near the second joint J2 is not bound by the fitting 200 on the back side of the hand.

図１８に示すように、第１挿入部３１０側に形成された支持部３４０は、手指Ｆの第２関節Ｊ２の関節線よりも指の付け根側に位置する手の腹部分に配置することができる。また、第２挿入部３２０側に形成された支持部３４０は、手指Ｆの第２関節Ｊ２の関節線よりも指の指先側に位置する手の腹部分に配置することができる。そのため、使用者が第２関節Ｊ２を基点にして手指Ｆを屈曲させる際、第２関節Ｊ２の関節線よりも指先側に位置する指の腹部分および第２関節Ｊ２の関節線よりも指の付け根側に位置する指の腹部分と装着具３００とが干渉することを防止できる。したがって、使用者は、支持部３４０により手指Ｆを掌側から支持させつつ、第２関節Ｊ２を基点にして手指Ｆを円滑に屈曲動作させることができる。 As shown in FIG. 18, the support portion 340 formed on the side of the first insertion portion 310 may be arranged on the abdominal portion of the hand located on the base side of the finger with respect to the joint line of the second joint J2 of the finger F. can. Further, the support portion 340 formed on the side of the second insertion portion 320 can be arranged on the abdominal portion of the hand located closer to the fingertip side of the joint line of the second joint J2 of the finger F. Therefore, when the user bends the finger F with respect to the second joint J2, the pad of the finger located closer to the fingertip side of the joint line of the second joint J2 and the finger than the joint line of the second joint J2. It is possible to prevent the pad of the finger located on the base side from interfering with the fitting 300. Therefore, the user can smoothly bend the finger F with the second joint J2 as the base point while supporting the finger F from the palm side by the support portion 340.

図１８に示すように、装着具３００を手指Ｆに装着させた際、第２関節Ｊ２は開口部３３０により露出される。また、第２関節Ｊ２よりも手指Ｆの付け根側の手の甲側に位置する部分は中間部３６０で押え付けられる。さらに、第２関節Ｊ２よりも手指Ｆの指先側の側部の一方側（例えば、手指Ｆの左側）は第２挿入部３２０により固定され、第２関節Ｊ２よりも手指Ｆの付け根側の側部（例えば、手指Ｆの右側）は第１挿入部３１０により固定される。使用者は、各挿入部３１０、３２０、支持部３４０、および中間部３６０により手指Ｆを固定することができるため、手指Ｆの側方への動揺を抑制することができる。 As shown in FIG. 18, when the fitting 300 is attached to the finger F, the second joint J2 is exposed by the opening 330. Further, the portion located on the back side of the hand on the base side of the finger F with respect to the second joint J2 is pressed by the intermediate portion 360. Further, one side (for example, the left side of the finger F) of the fingertip side of the finger F with respect to the second joint J2 is fixed by the second insertion portion 320, and the side of the base side of the finger F with respect to the second joint J2. The portion (for example, the right side of the finger F) is fixed by the first insertion portion 310. Since the user can fix the finger F by the insertion portions 310, 320, the support portion 340, and the intermediate portion 360, lateral sway of the finger F can be suppressed.

図１９には、第３実施形態の変形例に係る装着具３００Ａを示す。装着具３００Ａは、第１挿入部３１０および第２挿入部３３０がリング形状（円環形状）に形成されている。そのため、図２０に示すように、使用者が装着具３００Ａを手指Ｆに装着させると、各挿入部３１０、３２０により手指Ｆ１の所定の部位が外周方向に沿って支持される。したがって、手指Ｆに対する装着具３００Ａの固定力をより一層高めることができる。なお、図２０では、使用者の手指Ｆ１の第１関節Ｊ１側に装着具３００Ａを装着し、使用者の手指Ｆ２の第２関節Ｊ２側に装着具３００を装着した例を示しているが、装着具３００Ａを装着させる手指Ｆの位置について特に制限はない。また、使用者は、前述した各実施形態および各変形例で示した装着具を一つの手指および／または複数の手指の任意の箇所に選択的に組み合わせて同時に装着することも可能である。 FIG. 19 shows a fitting 300A according to a modified example of the third embodiment. In the fitting 300A, the first insertion portion 310 and the second insertion portion 330 are formed in a ring shape (annular shape). Therefore, as shown in FIG. 20, when the user attaches the wearing tool 300A to the finger F, the predetermined portions of the finger F1 are supported by the insertion portions 310 and 320 along the outer peripheral direction. Therefore, the fixing force of the attachment 300A to the finger F can be further increased. Note that FIG. 20 shows an example in which the fitting 300A is attached to the first joint J1 side of the user's finger F1 and the fitting 300 is attached to the second joint J2 side of the user's finger F2. There is no particular limitation on the position of the finger F on which the fitting 300A is attached. In addition, the user can selectively combine the wearing tools shown in the above-described embodiments and modifications to any position of one finger and / or a plurality of fingers and wear them at the same time.
