Description

本発明は、被測定部位に巻かれる帯状の血圧計用カフに関する。 The present invention relates to a band-shaped sphygmomanometer cuff wrapped around a measurement site.

従来、血圧計用カフは、略円筒状の一部が切欠かれて開口部を有する弾性体のコアを備え、開口部から挿入した上腕または手首に装着できるようにすると共に、装着した際に、容易に外れないように、上腕または手首をある程度覆うように構成される（例えば、特許文献１参照）。 Conventionally, a sphygmomanometer cuff has an elastic core having a substantially cylindrical portion cut out and has an opening so that it can be attached to an upper arm or wrist inserted through the opening, and when attached, it is attached. It is configured to cover the upper arm or wrist to some extent so that it does not easily come off (see, for example, Patent Document 1).

特開昭５９－５１８３７号公報Japanese Unexamined Patent Publication No. 59-51837

特許文献１には、カフ帯に人体の上腕に略沿うことができる湾曲板（コア）を収容し、湾曲板の両端間に人体の上腕を挿入することができる開口を形成する血圧計用カフが開示されている。また、特許文献１には、湾曲板の一端部が、外側にはね上げ変形した血圧計用カフが開示されている。 In Patent Document 1, a sphygmomanometer cuff that accommodates a curved plate (core) that can substantially follow the upper arm of the human body in a cuff band and forms an opening in which the upper arm of the human body can be inserted between both ends of the curved plate. Is disclosed. Further, Patent Document 1 discloses a sphygmomanometer cuff in which one end of a curved plate is flipped outward and deformed.

しかしながら、特許文献１に記載の血圧計用カフは、湾曲板の一端部が、他端部側に傾斜するように、はね上げ変形しているため、上腕を開口から湾曲板内に挿入する際に、このはね上げ変形した形状の先端に上腕が当たってしまい、装着性が悪い、という問題がある。 However, the sphygmomanometer cuff described in Patent Document 1 is deformed by flipping up so that one end of the curved plate is inclined toward the other end, and therefore, when the upper arm is inserted into the curved plate from the opening. There is a problem that the upper arm hits the tip of this flip-up deformed shape and the wearability is poor.

そこで、本発明は、容易に外れないようにすると共に、装着性を向上させた血圧計用カフを提供することを目的としている。 Therefore, an object of the present invention is to provide a sphygmomanometer cuff that is not easily removed and has improved wearability.

前記目的を達成するために、本発明の血圧計用カフは、被測定部位に巻くように装着されるカバー体に収容され、前記被測定部位に沿うように湾曲する弾性体のコアを備え、前記コアは、略円筒状の一部が切欠かれてなる開口を有する断面Ｃ字状のコア本体と、前記コア本体の端部から、前記コア本体の外側であって、前記コア本体の端部間を結ぶ平面の垂直面に対して遠ざかる方向に延在する返し部と、を備えることを特徴とする。 In order to achieve the above object, the sphygmomanometer cuff of the present invention is housed in a cover body wound around the measured portion, and includes an elastic core that curves along the measured portion. The core has a core body having a C-shaped cross section having an opening formed by cutting out a part of a substantially cylindrical shape, and an end portion of the core body which is outside the core body from the end portion of the core body. It is characterized by including a barb extending in a direction away from the vertical plane of the plane connecting the spaces.

このように構成された本発明の血圧計用カフは、容易に外れないようにすると共に、装着性を向上させることができる。 The sphygmomanometer cuff of the present invention configured in this way can be prevented from being easily removed and can be easily worn.

［手首装着型血圧計の構成］
図１は、実施例１の手首装着型血圧計用カフを備えた手首装着型血圧計の構成を示す斜視図である。図２は、実施例１の手首装着型血圧計用カフを備えた手首装着型血圧計の構成を示す断面図である。以下、図１および図２に基づいて、実施例１の手首装着型血圧計の構成を説明する。[Structure of wrist-worn sphygmomanometer]
FIG. 1 is a perspective view showing the configuration of a wrist-worn sphygmomanometer provided with a wrist-worn sphygmomanometer cuff according to the first embodiment. FIG. 2 is a cross-sectional view showing the configuration of a wrist-worn sphygmomanometer provided with a wrist-worn sphygmomanometer cuff according to the first embodiment. Hereinafter, the configuration of the wrist-worn sphygmomanometer of Example 1 will be described with reference to FIGS. 1 and 2.

手首装着型血圧計１は、図１に示すように、装置本体１０と、手首Ｍに巻き付けられる手首装着型血圧計用カフ２０と、を備える。装置本体１０の表面には、表示部１１と、操作部１２と、を備える。 As shown in FIG. 1, the wrist-mounted sphygmomanometer 1 includes a devicemain body 10 and a wrist-mountedsphygmomanometer cuff 20 wrapped around the wrist M. The surface of the apparatusmain body 10 is provided with adisplay unit 11 and anoperation unit 12.

装置本体１０は、手首装着型血圧計１が手首Ｍに装着された状態で、手の甲側から親指側にわたって配置され、被測定者が、表示部１１を視認し、操作部１２を操作可能なようになっている。装置本体１０の内部には、図示しないポンプ、スローリーク弁、圧力センサー等を内蔵する。 The devicemain body 10 is arranged from the back side of the hand to the thumb side with the wrist-mounted blood pressure monitor 1 attached to the wrist M so that the person to be measured can visually recognize thedisplay unit 11 and operate theoperation unit 12. It has become. A pump, a slow leak valve, a pressure sensor, etc. (not shown) are built in the devicemain body 10.

手首装着型血圧計用カフ２０は、図２に示すように、手首Ｍに巻くように装着されるカバー体２１と、カバー体２１の内部に収容される空気袋２２およびコア３０と、を備える。 As shown in FIG. 2, the wrist-worn sphygmomanometer cuff 20 includes acover body 21 that is wound around the wrist M, and anair bag 22 and acore 30 that are housed inside thecover body 21. ..

カバー体２１は、帯状の布等で形成され、手首Ｍの一般的な周長よりも長く形成される。カバー体２１の折り返し部２１ａの近傍には、面ファスナ２３が取り付けられる。面ファスナ２３は、装置本体１０の上面に設けられた面ファスナ２４に押し付けることで固定される。 Thecover body 21 is formed of a band-shaped cloth or the like, and is formed longer than the general peripheral length of the wrist M. A hook-and-loop fastener 23 is attached in the vicinity of the folded-back portion 21a of thecover body 21. The surface fastener 23 is fixed by pressing against thesurface fastener 24 provided on the upper surface of the apparatusmain body 10.

空気袋２２は、樹脂シートにより形成された袋状の部材から形成される。空気袋２２は、装置本体１０のポンプから導入された空気により膨張する。 Theair bag 22 is formed of a bag-shaped member formed of a resin sheet. Theair bag 22 is expanded by the air introduced from the pump of the apparatusmain body 10.

このように構成された手首装着型血圧計１では、手首装着型血圧計用カフ２０を手首Ｍに巻き、面ファスナ２３と面ファスナ２４とを貼り付けることで、手首装着型血圧計１を被測定者の手首Ｍに装着する。手首装着型血圧計１を被測定者の手首Ｍに装着した状態で、操作部１２を操作することで、装置本体１０のポンプから、空気袋２２の内部に、空気が導入される。空気袋２２に空気が導入されると、手首Ｍの動脈が圧迫される。 In the wrist-mounted sphygmomanometer 1 configured in this way, the wrist-mounted sphygmomanometer 1 is covered by wrapping the wrist-mountedsphygmomanometer cuff 20 around the wrist M and attaching the surface fastener 23 and thesurface fastener 24. It is attached to the wrist M of the measurer. By operating theoperation unit 12 with the wrist-mounted blood pressure monitor 1 attached to the wrist M of the person to be measured, air is introduced from the pump of the apparatusmain body 10 into the inside of theair bag 22. When air is introduced into theair bag 22, the artery of the wrist M is compressed.

その後、装置本体１０に内蔵されているポンプの駆動が止められ、空気袋２２内の空気を、装置本体１０に内蔵されたスローリーク弁より徐々に抜くことにより、空気袋２２内の圧力を下げる。このとき、手首Ｍの動脈の脈動による空気袋２２内の圧力の変化を、装置本体１０に内蔵された圧力センサーにて検出し、表示部１１に表示するようになっている。 After that, the drive of the pump built in the devicemain body 10 is stopped, and the air in theair bag 22 is gradually removed from the slow leak valve built in the devicemain body 10 to reduce the pressure in theair bag 22. .. At this time, the change in pressure in theair bag 22 due to the pulsation of the artery of the wrist M is detected by the pressure sensor built in the apparatusmain body 10 and displayed on thedisplay unit 11.

［コアの構成］
図３は、実施例１の手首装着型血圧計用カフのコアの構成を示す側面図である。以下、図３に基づいて、実施例１の手首装着型血圧計のコアの構成を説明する。[Core configuration]
FIG. 3 is a side view showing the configuration of the core of the wrist-worn sphygmomanometer cuff according to the first embodiment. Hereinafter, the configuration of the core of the wrist-worn sphygmomanometer of Example 1 will be described with reference to FIG.

コア３０は、可とう性を有する弾性体で形成され、図３に示すように、手首Ｍに沿うように湾曲するコア本体３１と、コア本体３１から張り出した返し部３６ａと、から構成される。 Thecore 30 is formed of a flexible elastic body, and as shown in FIG. 3, is composed of a coremain body 31 that curves along the wrist M and areturn portion 36a that projects from the coremain body 31. ..

コア本体３１は、断面略円弧状の底部３２と、底部３２の両端から起立する側壁部３３ａ，３３ｂと、側壁部３３ａ，３３ｂの先端から内側に屈曲して形成される窄み部３４ａ，３４ｂと、から構成される。 The coremain body 31 has abottom portion 32 having a substantially arcuate cross section,side wall portions 33a and 33b rising from both ends of thebottom portion 32, and narrowedportions 34a and 34b formed by bending inward from the tips of theside wall portions 33a and 33b. And consists of.

窄み部３４ａ，３４ｂの端部３５ａ，３５ｂは、開放端として形成される。端部３５ａと、端部３５ｂとの間には、開口長ｈの開口５０が形成される。開口５０は、図３の上下方向において、コア本体３１の略中央に形成される。図３の左右方向において、端部３５ａと、端部３５ｂとは、略同じ位置にある。 Theends 35a, 35b of the narrowedportions 34a, 34b are formed as open ends. An opening 50 having an opening length h is formed between theend portion 35a and theend portion 35b. The opening 50 is formed substantially in the center of thecore body 31 in the vertical direction of FIG. In the left-right direction of FIG. 3, theend portion 35a and theend portion 35b are at substantially the same position.

すなわち、コア本体３１は、略円筒状の一部が切欠かれてなる開口５０を有する断面Ｃ字状に形成される。なお、開口長ｈは、断面Ｃ形状を形成する端部３５ａと端部３５ｂとの最短距離とする。 That is, the coremain body 31 is formed in a C-shaped cross section having anopening 50 formed by cutting out a part of a substantially cylindrical shape. The opening length h is the shortest distance between theend portion 35a and theend portion 35b forming the cross-sectional C shape.

返し部３６ａは、コア本体３１の端部３５ａから、コア本体３１の外側であって、コア本体３１の端部３５ａ，３５ｂ間を結ぶ平面Ｐ１の垂直面Ｐ２に対して遠ざかる方向に延在する。言い換えると、返し部３６ａは、断面Ｃ字状を形成する端部３５ａ，３５ｂのうち、装置本体１０が取り付けられる側（図３で上側）の端部３５ａから、コア本体３１の外周面の外側で、開口５０が広がる方向に張り出して形成される。返し部３６ａの側面３７ａは、平坦に形成される。 Thereturn portion 36a extends from theend portion 35a of the coremain body 31 in a direction away from the vertical surface P2 of the plane P1 which is outside the coremain body 31 and connects theends 35a and 35b of the coremain body 31. .. In other words, thereturn portion 36a is outside the outer peripheral surface of the coremain body 31 from theend portion 35a on the side (upper side in FIG. 3) to which the devicemain body 10 is attached among theend portions 35a and 35b forming a C-shaped cross section. The opening 50 is formed so as to project in the direction of widening. Theside surface 37a of thereturn portion 36a is formed flat.

なお、返し部３６ａの側面３７ａは、曲面形状であってもよい。また、返し部３６ａは、断面Ｃ字状を形成する端部３５ａ，３５ｂのうち、装置本体１０が取り付けられる側（図３で上側）の端部３５ａとは反対側の端部３５ｂから、コア本体３１の外周面の外側で、開口５０が広がる方向に張り出して形成されてもよい。 Theside surface 37a of thereturn portion 36a may have a curved surface shape. Further, thereturn portion 36a has a core from theend portions 35a and 35b forming a C-shaped cross section, which are opposite to theend portion 35a on the side where the devicemain body 10 is attached (upper side in FIG. 3). It may be formed so as to project on the outside of the outer peripheral surface of themain body 31 in the direction in which theopening 50 expands.

次に、実施例１の手首装着型血圧計用カフ２０の作用を説明する。
図４Ａは、実施例１の手首装着型血圧計用カフの作用を説明する説明図であり、手首が返し部の側面に当接した状態を示す。図４Ｂは、実施例１の手首装着型血圧計用カフの作用を説明する説明図であり、開口が広げられた状態を示す。Next, the operation of the wrist-wornsphygmomanometer cuff 20 of Example 1 will be described.
FIG. 4A is an explanatory diagram illustrating the operation of the wrist-worn sphygmomanometer cuff of Example 1, and shows a state in which the wrist is in contact with the side surface of the return portion. FIG. 4B is an explanatory diagram illustrating the operation of the wrist-worn sphygmomanometer cuff of Example 1, and shows a state in which the opening is widened.

実施例１の手首装着型血圧計用カフ２０は、被測定部位（手首Ｍ）に巻くように装着されるカバー体２１に収容され、被測定部位（手首Ｍ）に沿うように湾曲する弾性体のコア３０を備える。コア３０は、略円筒状の一部が切欠かれてなる開口を有する断面Ｃ字状のコア本体３１と、コア本体３１の端部３５ａから、コア本体３１の外側であって、コア本体３１の端部間を結ぶ平面Ｐ１の垂直面Ｐ２に対して遠ざかる方向に延在する返し部３６ａと、を備える（図３）。 The wrist-wornsphygmomanometer cuff 20 of Example 1 is housed in acover body 21 that is wound around the measured portion (wrist M) and is an elastic body that curves along the measured portion (wrist M). Thecore 30 is provided. Thecore 30 is a coremain body 31 having a C-shaped cross section having an opening formed by cutting out a part of a substantially cylindrical shape, and the coremain body 31 is outside the coremain body 31 from theend portion 35a of the coremain body 31. Areturn portion 36a extending in a direction away from the vertical plane P2 of the plane P1 connecting the ends is provided (FIG. 3).

手首装着型血圧計用カフ２０を手首Ｍに装着する際は、図４Ａに示すように、被測定者が、装置本体１０を手で持ち、手首装着型血圧計用カフ２０の開口５１を、被測定者の手首Ｍに向けて移動させる。ここで、手首装着型血圧計用カフ２０の開口５１は、コア本体３１の開口５０に対し、カバー体２１の厚みを考慮したものであり、開口５０と相関関係にある。 When the wrist-mountedsphygmomanometer cuff 20 is attached to the wrist M, as shown in FIG. 4A, the person to be measured holds thedevice body 10 by hand and opens theopening 51 of the wrist-mountedsphygmomanometer cuff 20. Move toward the wrist M of the person to be measured. Here, theopening 51 of the wrist-wornsphygmomanometer cuff 20 takes into consideration the thickness of thecover body 21 with respect to theopening 50 of the coremain body 31, and has a correlation with theopening 50.

手首装着型血圧計用カフ２０が、手首Ｍに近づくと、手首Ｍが、カバー体２１を介して、返し部３６ａの側面３７ａに当たる。手首Ｍが、カバー体２１を介して、返し部３６ａの側面３７ａに当たった状態で、手首装着型血圧計１を手首Ｍに近づく方向に移動させると、側面３７ａが手首Ｍに押される。 When the wrist-wornsphygmomanometer cuff 20 approaches the wrist M, the wrist M hits theside surface 37a of thereturn portion 36a via thecover body 21. When the wrist-mounted sphygmomanometer 1 is moved in a direction approaching the wrist M while the wrist M is in contact with theside surface 37a of thereturn portion 36a via thecover body 21, theside surface 37a is pushed by the wrist M.

側面３７ａが手首Ｍに押されると、図４Ｂに示すように、コア本体３１の形状が変形し、開口５１が開口長Ｈより長い開口長Ｈａとなり、開口５１が広がる。開口５１が広がった状態で、手首装着型血圧計１を手首Ｍに近づく方向にさらに移動させると、手首Ｍが、開口５１を通過し、手首装着型血圧計用カフ２０が手首Ｍに装着される。 When theside surface 37a is pushed by the wrist M, as shown in FIG. 4B, the shape of the coremain body 31 is deformed, theopening 51 becomes an opening length Ha longer than the opening length H, and theopening 51 expands. When the wrist-mounted sphygmomanometer 1 is further moved toward the wrist M with theopening 51 widened, the wrist M passes through theopening 51, and the wrist-mountedsphygmomanometer cuff 20 is attached to the wrist M. To.

すなわち、手首装着型血圧計１を手首Ｍに装着する際に、手首Ｍを返し部３６ａの側面３７ａに押し付けて、コア本体３１の開口５０が開く方向に、コア３０を変形させることができる。そのため、手首装着型血圧計用カフ２０の手首Ｍへの装着性を向上させることができる。 That is, when the wrist-mounted blood pressure monitor 1 is attached to the wrist M, the wrist M can be pressed against theside surface 37a of thereturn portion 36a to deform the core 30 in the direction in which theopening 50 of thecore body 31 opens. Therefore, it is possible to improve the wearability of the wrist-mounted bloodpressure monitor cuff 20 to the wrist M.

仮に、窄み部３４ａ，３４ｂを設けずに開口５０を大きくしてしまうと、コア本体３１が手首Ｍを保持する保持力が低下し、手首装着型血圧計用カフ２０と手首Ｍとの間に隙間が生じてしまう問題がある。一方、窄み部３４ａ，３４ｂを設けると、開口５０が狭くなり、手首Ｍを手首装着型血圧計用カフ２０の内側に挿入する際に、窄み部３４ａ，３４ｂが手首Ｍに当たってしまう、という問題がある。これに対し、実施例１の手首装着型血圧計１は、窄み部３４ａ，３４ｂを設け、さらに返し部３６ａを設ける構成により、手首Ｍを返し部３６ａの側面３７ａに押し当てて、開口５１を広げることができる。そのため、手首Ｍを手首装着型血圧計用カフ２０の内側に挿入し易くすることができる。 If theopening 50 is enlarged without providing the narrowedportions 34a and 34b, the holding force of thecore body 31 to hold the wrist M is reduced, and the space between the wrist-mounted bloodpressure monitor cuff 20 and the wrist M is reduced. There is a problem that a gap is created in the blood pressure. On the other hand, if the narrowedportions 34a and 34b are provided, theopening 50 becomes narrow and the narrowedportions 34a and 34b hit the wrist M when the wrist M is inserted inside the wrist-wornsphygmomanometer cuff 20. There's a problem. On the other hand, in the wrist-worn sphygmomanometer 1 of the first embodiment, the wrist M is pressed against theside surface 37a of thereturn portion 36a and theopening 51 is provided by providing the narrowedportions 34a and 34b and further providing thereturn portion 36a. Can be expanded. Therefore, the wrist M can be easily inserted into the wrist-wornsphygmomanometer cuff 20.

まず、実施例２における手首装着型血圧計用カフの構成を説明する。
図５Ａは、実施例２の手首装着型血圧計用カフの構成と作用を説明する説明図であり、手首が返し部の側面に当接した状態を示す。図５Ｂは、実施例２の手首装着型血圧計用カフの作用を説明する説明図であり、開口が広げられた状態を示す。なお、実施例１で説明した内容と同一乃至均等な部分の説明については、同一用語又は同一の符号を用いて説明する。First, the configuration of the wrist-worn sphygmomanometer cuff in Example 2 will be described.
FIG. 5A is an explanatory diagram illustrating the configuration and operation of the wrist-worn sphygmomanometer cuff according to the second embodiment, and shows a state in which the wrist is in contact with the side surface of the return portion. FIG. 5B is an explanatory diagram illustrating the operation of the wrist-worn sphygmomanometer cuff of Example 2, and shows a state in which the opening is widened. The same or equivalent parts as those described in Example 1 will be described using the same terms or the same reference numerals.

実施例２の手首装着型血圧計用カフ１２０は、コアの返し部の構成が異なる点で実施例１の手首装着型血圧計用カフ２０と相違する。 The wrist-wornsphygmomanometer cuff 120 of Example 2 is different from the wrist-wornsphygmomanometer cuff 20 of Example 1 in that the configuration of the return portion of the core is different.

［コアの返し部の構成］
実施例２もコア１３０は、図５Ａに示すように、返し部３６ａの先端から、コア本体１３１に近づく方向に屈曲して形成される第２返し部１３８ａを備える。返し部３６ａの側面３７ａと、第２返し部１３８ａの側面１３９ａとは、滑らかな曲面で接続される。[Structure of core return part]
Also in the second embodiment, as shown in FIG. 5A, thecore 130 includes asecond return portion 138a formed by bending from the tip of thereturn portion 36a in a direction approaching the core main body 131. Theside surface 37a of thereturn portion 36a and theside surface 139a of thesecond return portion 138a are connected by a smooth curved surface.

次に、実施例２の手首装着型血圧計用カフ１２０の作用を説明する。
実施例２の手首装着型血圧計用カフ１２０は、コア３０は、返し部３６ａの先端から、コア本体３１に近づく方向に屈曲して形成される第２返し部１３８ａを備える（図５Ａ）。Next, the operation of the wrist-wornsphygmomanometer cuff 120 of Example 2 will be described.
The wrist-wornsphygmomanometer cuff 120 of Example 2 includes asecond return portion 138a formed by bending the core 30 from the tip of thereturn portion 36a in a direction approaching the core main body 31 (FIG. 5A).

手首装着型血圧計用カフ１２０を手首Ｍに装着する際は、図５Ａに示すように、被測定者が、装置本体１０を手で持ち、手首装着型血圧計用カフ１２０の開口５１を、被測定者の手首Ｍに向けて移動させる。手首装着型血圧計用カフ１２０が、手首Ｍに近づくと、手首Ｍが、カバー体２１を介して、返し部３６ａの側面３７ａに当たる。 When the wrist-mountedsphygmomanometer cuff 120 is attached to the wrist M, as shown in FIG. 5A, the person to be measured holds thedevice body 10 by hand and opens theopening 51 of the wrist-mountedsphygmomanometer cuff 120. Move toward the wrist M of the person to be measured. When the wrist-wornsphygmomanometer cuff 120 approaches the wrist M, the wrist M hits theside surface 37a of thereturn portion 36a via thecover body 21.

この際、返し部３６ａの先端には、第２返し部１３８ａが形成されているため、返し部３６ａの先端が手首Ｍに当たることを防止する。 At this time, since thesecond return portion 138a is formed at the tip of thereturn portion 36a, it is possible to prevent the tip of thereturn portion 36a from hitting the wrist M.

手首Ｍが、カバー体２１を介して、返し部３６ａの側面３７ａに当たった状態で、手首装着型血圧計１０１を手首Ｍに近づく方向に移動させると、側面３７ａが手首Ｍに押される。側面３７ａが手首Ｍに押されると、図５Ｂに示すように、コア本体３１の形状が変形し、開口５１が開口長Ｈより長い開口長Ｈａとなり、開口５１が広がる。 When the wrist-mountedsphygmomanometer 101 is moved in a direction approaching the wrist M while the wrist M is in contact with theside surface 37a of thereturn portion 36a via thecover body 21, theside surface 37a is pushed by the wrist M. When theside surface 37a is pushed by the wrist M, as shown in FIG. 5B, the shape of the coremain body 31 is deformed, theopening 51 becomes an opening length Ha longer than the opening length H, and theopening 51 expands.

開口５１が広がった状態で、手首装着型血圧計１０１を手首Ｍに近づく方向にさらに移動させると、手首Ｍが、開口５１を通過し、手首装着型血圧計用カフ１２０が手首Ｍに装着される。 When the wrist-mountedsphygmomanometer 101 is further moved toward the wrist M with theopening 51 widened, the wrist M passes through theopening 51, and the wrist-mountedsphygmomanometer cuff 120 is attached to the wrist M. To.

すなわち、手首装着型血圧計用カフ１２０を手首Ｍに装着させる際に、手首Ｍを返し部３６ａの側面３７ａに確実に当てることができる。そのため、手首装着型血圧計用カフ１２０の手首Ｍへの装着性をさらに向上させることができる。なお、実施例１で説明した内容と同一乃至均等な部分の説明については、同一用語又は同一の符号を用いて説明する。 That is, when the wrist-mounted bloodpressure monitor cuff 120 is attached to the wrist M, the wrist M can be reliably applied to theside surface 37a of thereturn portion 36a. Therefore, the wearability of the wrist-wornsphygmomanometer cuff 120 to the wrist M can be further improved. The same or equivalent parts as those described in Example 1 will be described using the same terms or the same reference numerals.

まず、実施例３における手首装着型血圧計用カフの構成を説明する。
図６Ａは、実施例３の手首装着型血圧計用カフの構成と作用を説明する説明図であり、手首が返し部の側面に当接した状態を示す。図６Ｂは、実施例３の手首装着型血圧計用カフの作用を説明する説明図であり、開口が広げられた状態を示す。なお、実施例１で説明した内容と同一乃至均等な部分の説明については、同一用語又は同一の符号を用いて説明する。First, the configuration of the wrist-worn sphygmomanometer cuff in Example 3 will be described.
FIG. 6A is an explanatory diagram illustrating the configuration and operation of the wrist-worn sphygmomanometer cuff according to the third embodiment, showing a state in which the wrist is in contact with the side surface of the return portion. FIG. 6B is an explanatory diagram illustrating the operation of the wrist-worn sphygmomanometer cuff according to the third embodiment, and shows a state in which the opening is widened. The same or equivalent parts as those described in Example 1 will be described using the same terms or the same reference numerals.

実施例３の手首装着型血圧計用カフ２２０は、コアの返し部の構成が異なる点で実施例１の手首装着型血圧計用カフ２０と相違する。 The wrist-wornsphygmomanometer cuff 220 of Example 3 is different from the wrist-wornsphygmomanometer cuff 20 of Example 1 in that the configuration of the return portion of the core is different.

［コアの返し部の構成］
図６Ａに示すように、コア本体２３１の底部３２から、コア本体２３１の装置本体１０が取り付けられる側の端部２３５ａまでの距離は、コア本体２３１の底部３２から、コア本体２３１の装置本体１０が取り付けられる側とは反対側の端部２３５ｂまでの距離より長く形成される。すなわち、コア本体２３１の装置本体１０が取り付けられる側の端部２３５ａは、コア本体２３１の装置本体１０が取り付けられる側とは反対側の端部２３５ｂより突出して設けられる。[Structure of core return part]
As shown in FIG. 6A, the distance from the bottom 32 of thecore body 231 to theend 235a on the side where thedevice body 10 of thecore body 231 is attached is from the bottom 32 of thecore body 231 to thedevice body 10 of thecore body 231. Is formed longer than the distance to theend 235b on the side opposite to the side to which is attached. That is, theend portion 235a on the side of the coremain body 231 on which the devicemain body 10 is attached is provided so as to project from theend portion 235b on the side opposite to the side on which the devicemain body 10 of the coremain body 231 is attached.

コア本体２３１の端部２３５ａから、コア本体２３１の外側であって、コア本体２３１の端部２３５ａ，２３５ｂ間を結ぶ平面Ｐ１の垂直面Ｐ２に対して遠ざかる方向に延在する。言い換えると、コア本体２３１の端部２３５ａから、コア本体２３１の外周面の外側で、開口５０が広がる方向に張り出して返し部３６ａが形成される。 It extends from theend portion 235a of the coremain body 231 in a direction away from the vertical surface P2 of the plane P1 which is outside the coremain body 231 and connects theends 235a and 235b of the coremain body 231. In other words, from theend portion 235a of the coremain body 231 to the outside of the outer peripheral surface of the coremain body 231, thereturn portion 36a is formed so as to project in the direction in which theopening 50 widens.

なお、コア本体２３１の装置本体１０が取り付けられる側とは反対側の端部２３５ｂが、コア本体２３１の装置本体１０が取り付けられる側の端部２３５ａより突出して設けられてもよい。この場合、コア本体２３１の端部２３５ｂから、コア本体２３１の外周面の外側で、開口５０が広がる方向に張り出して返し部が形成される。 It should be noted that theend portion 235b on the side of the coremain body 231 opposite to the side on which the devicemain body 10 is attached may be provided so as to protrude from theend portion 235a on the side on which the apparatusmain body 10 of the coremain body 231 is attached. In this case, a return portion is formed so as to project from theend portion 235b of the coremain body 231 in the direction in which theopening 50 expands on the outside of the outer peripheral surface of the coremain body 231.

次に、実施例３の手首装着型血圧計用カフ２２０の作用を説明する。
実施例３の手首装着型血圧計用カフ２２０は、コア本体３１の一方の端部２３５ａは、コア本体の他方の端部２３５ｂより突出して設けられ、返し部３６ａは、少なくとも突出して設けられたコア本体３１の一方の端部２３５ａに設けられる（図６Ａ）。Next, the operation of the wrist-wornsphygmomanometer cuff 220 of Example 3 will be described.
In the wrist-wornsphygmomanometer cuff 220 of Example 3, oneend 235a of thecore body 31 is provided so as to protrude from theother end 235b of the core body, and thereturn portion 36a is provided at least so as to protrude. It is provided at oneend 235a of the core body 31 (FIG. 6A).

手首装着型血圧計用カフ２２０を手首Ｍに装着する際は、図６Ａに示すように、被測定者が、装置本体１０を手で持ち、手首装着型血圧計用カフ２２０の開口５１を、被測定者の手首Ｍに向けて移動させる。手首装着型血圧計用カフ２２０が、手首Ｍに近づくと、手首Ｍが、カバー体２１を介して、返し部３６ａの側面３７ａに当たる。 When the wrist-mountedsphygmomanometer cuff 220 is attached to the wrist M, as shown in FIG. 6A, the person to be measured holds thedevice body 10 by hand and opens theopening 51 of the wrist-mountedsphygmomanometer cuff 220. Move toward the wrist M of the person to be measured. When the wrist-wornsphygmomanometer cuff 220 approaches the wrist M, the wrist M hits theside surface 37a of thereturn portion 36a via thecover body 21.

この際、返し部３６ａは、手首Ｍの手首装着型血圧計用カフ２２０への挿入軌跡で、コア本体２３１の端部２３６ｂより、手前側にある。そのため、返し部３６ａの側面３７ａを、手首Ｍの手首装着型血圧計用カフ２２０への挿入軌跡で、手首Ｍに最初に当てることができる。 At this time, thereturn portion 36a is an insertion locus of the wrist M into the wrist-wornsphygmomanometer cuff 220, and is on the front side of the end portion 236b of the coremain body 231. Therefore, theside surface 37a of thereturn portion 36a can be first applied to the wrist M by the insertion locus of the wrist M into the wrist-wornsphygmomanometer cuff 220.

手首Ｍが、カバー体２１を介して、返し部３６ａの側面３７ａに当たった状態で、手首装着型血圧計２０１を手首Ｍに近づく方向に移動させると、側面３７ａが手首Ｍに押される。側面３７ａが手首Ｍに押されると、図６Ｂに示すように、コア本体２３１の形状が変形し、開口５１が開口長Ｈより長い開口長Ｈａとなり、開口５１が広がる。 When the wrist-mountedsphygmomanometer 201 is moved in a direction approaching the wrist M while the wrist M is in contact with theside surface 37a of thereturn portion 36a via thecover body 21, theside surface 37a is pushed by the wrist M. When theside surface 37a is pushed by the wrist M, as shown in FIG. 6B, the shape of the coremain body 231 is deformed, theopening 51 becomes an opening length Ha longer than the opening length H, and theopening 51 expands.

開口５１が広がった状態で、手首装着型血圧計２０１を手首Ｍに近づく方向にさらに移動させると、手首Ｍが、開口５０を通過し、手首装着型血圧計用カフ２２０が手首Ｍに装着される。 When the wrist-mountedsphygmomanometer 201 is further moved toward the wrist M with theopening 51 widened, the wrist M passes through theopening 50, and the wrist-mountedsphygmomanometer cuff 220 is attached to the wrist M. To.

すなわち、手首装着型血圧計用カフ２２０を手首Ｍに装着する軌跡において、手首Ｍを、一方の端部２３５ａに設けられた返し部３６ａの側面３７ａに最初に当てることができる。そのため、手首装着型血圧計用カフ２２０の手首Ｍへの装着性をさらに向上させることができる。なお、実施例１で説明した内容と同一乃至均等な部分の説明については、同一用語又は同一の符号を用いて説明する。 That is, in the locus of attaching the wrist-mounted bloodpressure monitor cuff 220 to the wrist M, the wrist M can be first applied to theside surface 37a of thereturn portion 36a provided at oneend portion 235a. Therefore, the wearability of the wrist-mounted bloodpressure monitor cuff 220 to the wrist M can be further improved. The same or equivalent parts as those described in Example 1 will be described using the same terms or the same reference numerals.

まず、実施例４における手首装着型血圧計用カフの構成を説明する。
図７Ａは、実施例４の手首装着型血圧計用カフの構成と作用を説明する説明図であり、手首が返し部の側面に当接した状態を示す。図７Ｂは、実施例４の手首装着型血圧計用カフの作用を説明する説明図であり、開口が広げられた状態を示す。なお、実施例１で説明した内容と同一乃至均等な部分の説明については、同一用語又は同一の符号を用いて説明する。First, the configuration of the wrist-worn sphygmomanometer cuff in Example 4 will be described.
FIG. 7A is an explanatory diagram illustrating the configuration and operation of the wrist-worn sphygmomanometer cuff according to the fourth embodiment, showing a state in which the wrist is in contact with the side surface of the return portion. FIG. 7B is an explanatory diagram illustrating the operation of the wrist-worn sphygmomanometer cuff of Example 4, and shows a state in which the opening is widened. The same or equivalent parts as those described in Example 1 will be described using the same terms or the same reference numerals.

実施例４の手首装着型血圧計用カフ３２０は、コアの返し部の構成が異なる点で実施例１の手首装着型血圧計用カフ２０と相違する。 The wrist-wornsphygmomanometer cuff 320 of Example 4 is different from the wrist-wornsphygmomanometer cuff 20 of Example 1 in that the configuration of the return portion of the core is different.

［コアの返し部の構成］
実施例４のコア３３０の返し部３６ａ，２３６ａは、図７Ａに示すように、コア本体３１の端部３５ａ，３５ｂの両方から、コア本体３１の外周面の外側で、コア本体３１の端部３５ａ，３５ｂ間を結ぶ平面Ｐ１の垂直面Ｐ２に対して遠ざかる方向に延在する。言い換えると、返し部３６ａ，２３６ａは、断面Ｃ字状を形成する端部３５ａ，３５ｂの両方から、コア本体３１の外周面の外側で、開口５０が広がる方向に張り出して形成される。[Structure of core return part]
As shown in FIG. 7A, thereturn portions 36a and 236a of thecore 330 of the fourth embodiment are the end portions of the coremain body 31 on the outside of the outer peripheral surface of the coremain body 31 from both theend portions 35a and 35b of the coremain body 31. It extends in a direction away from the vertical plane P2 of the plane P1 connecting 35a and 35b. In other words, thereturn portions 36a and 236a are formed so as to project from both theend portions 35a and 35b forming the C-shaped cross section on the outside of the outer peripheral surface of the coremain body 31 in the direction in which theopening 50 expands.

次に、実施例４の手首装着型血圧計用カフ３２０の作用を説明する。
手首装着型血圧計用カフ３２０を手首Ｍに装着する際は、図７Ａに示すように、被測定者が、装置本体１０を手で持ち、手首装着型血圧計用カフ３２０の開口５１を、被測定者の被測定部位である手首Ｍに向けて移動させる。Next, the operation of the wrist-wornsphygmomanometer cuff 320 of Example 4 will be described.
When the wrist-mountedsphygmomanometer cuff 320 is attached to the wrist M, as shown in FIG. 7A, the person to be measured holds thedevice body 10 by hand and opens theopening 51 of the wrist-mountedsphygmomanometer cuff 320. It is moved toward the wrist M, which is the measurement site of the person to be measured.

手首装着型血圧計用カフ３２０が、手首Ｍに近づくと、手首Ｍが、カバー体２１を介して、返し部３６ａの側面３７ａと、返し部３３６ｂの側面３３７ｂとの少なくとも一方に当たる。手首Ｍが、カバー体２１を介して、返し部３６ａの側面３７ａと、返し部３３６ｂの側面３３７ｂとの少なくとも一方に当たった状態で、手首装着型血圧計１を手首Ｍに近づく方向に移動させると、手首Ｍが当たっている側面３７ａ，３３７ｂが手首Ｍに押される。 When the wrist-wornsphygmomanometer cuff 320 approaches the wrist M, the wrist M hits at least one of theside surface 37a of thereturn portion 36a and theside surface 337b of thereturn portion 336b via thecover body 21. The wrist-mounted sphygmomanometer 1 is moved toward the wrist M in a state where the wrist M is in contact with at least one of theside surface 37a of thereturn portion 36a and theside surface 337b of thereturn portion 336b via thecover body 21. Then, the side surfaces 37a and 337b that the wrist M hits are pushed by the wrist M.

側面３７ａ，３３７ｂが手首Ｍに押されると、図７Ｂに示すように、コア本体２３１の形状が変形し、開口５１が開口長Ｈより長い開口長Ｈａとなり、開口５１が広がる。開口５１が広がった状態で、手首装着型血圧計３０１を手首Ｍに近づく方向にさらに移動させると、手首Ｍが、開口５０を通過し、手首装着型血圧計用カフ２２０が手首Ｍに装着される。 When the side surfaces 37a and 337b are pushed by the wrist M, as shown in FIG. 7B, the shape of the coremain body 231 is deformed, theopening 51 becomes an opening length Ha longer than the opening length H, and theopening 51 expands. When the wrist-mountedsphygmomanometer 301 is further moved toward the wrist M with theopening 51 widened, the wrist M passes through theopening 50, and the wrist-mountedsphygmomanometer cuff 220 is attached to the wrist M. To.

すなわち、手首装着型血圧計用カフ３２０を手首Ｍに装着する際に、手首Ｍを、少なくとも一方の返し部３６ａ，２３６ａの側面３７ａ，２３７ａに押し付けて、コアの開口が開く方向に、コアを変形させることができる。そのため、手首装着型血圧計用カフ３２０の手首Ｍへの装着性をさらに向上させることができる。なお、実施例１で説明した内容と同一乃至均等な部分の説明については、同一用語又は同一の符号を用いて説明する。 That is, when the wrist-mounted bloodpressure monitor cuff 320 is attached to the wrist M, the wrist M is pressed against the side surfaces 37a, 237a of at least one of thereturn portions 36a, 236a, and the core is opened in the direction in which the opening of the core is opened. It can be transformed. Therefore, the wearability of the wrist-wornsphygmomanometer cuff 320 to the wrist M can be further improved. The same or equivalent parts as those described in Example 1 will be described using the same terms or the same reference numerals.
