Description

本発明は、呼吸訓練装置に関する。   The present invention relates to a breathing training apparatus.

従来より、呼吸の訓練を行うための呼吸器官鍛錬器が知られている（例えば、特許文献１参照）。呼吸器官鍛錬器は、訓練モードと、測定モードとの切換えを可能とする調節体を備えている。調節体を回転させて、小径の排出口のみが開口するようにすることにより気流抵抗が大となり、訓練モードとして使用可能である。また、全排出口が開口することにより、気流抵抗は小となり、測定モードとして使用可能である。   BACKGROUND ART Conventionally, a respiratory organ trainer for breathing training has been known (see, for example, Patent Document 1). The respiratory organ trainer has a controller that enables switching between the training mode and the measurement mode. By rotating the adjuster so that only the small-diameter outlet is open, the air flow resistance is increased and can be used as a training mode. In addition, the air flow resistance is reduced by opening all the discharge ports, and can be used as a measurement mode.

The annular member 242 has a cylindrical portion 243 and a cylindrical portion 244 with a flange, to which grease is applied, respectively.

円筒状部２４３は、軸方向における長さが短く構成されており、円筒状部２４３の軸方向における一端部は、内径が小さく構成されている。この内径が小さく構成された部分の端面、即ち、円環状部材２４２の軸方向における端面には、円筒状部２４３と同軸的に形成された環状の凹部が形成されており、環状の凹部には、Ｏリング２４６が嵌合して設けられている。   The cylindrical portion 243 is configured to have a short length in the axial direction, and one end portion of the cylindrical portion 243 in the axial direction is configured to have a small inner diameter. An annular recess formed coaxially with the cylindrical portion 243 is formed on the end face of the portion having a small inner diameter, that is, the end face in the axial direction of the annular member 242, and the annular recess is formed , And an O-ring 246 is provided.

フランジ部付き円筒状部２４４は、円筒状部２４３の外径に等しい内径を有する円筒状の部分を有している。円筒状の部分は円筒状部２４３の内部に同軸的に挿入され、円筒状の部分の一端部と、円筒状部２４３の一端部の径が小さい部分とによりメッシュ部２４１の周縁部が挟まれて、メッシュ部２４１は円環状部材２４２に固定されている。フランジ部付き円筒状部２４４の円筒状の部分の他端部は、フランジ部を有している。   The flanged cylindrical portion 244 has a cylindrical portion having an inner diameter equal to the outer diameter of the cylindrical portion 243.

A part of the air flow path partitioned by the plurality of mesh bodies 24 is formed. That is, as shown in FIG. 2, from the mesh body 24 mounted at a position closest to the inflow port 21 to the mesh body 24 mounted at a position farthest from the inflow port 21, the annular members 242 are grease and They are in close tight contact with each other via an O-ring 246, and as shown in FIG. 2, air flow paths are formed so that air does not leak from the middle of the ten mounted mesh members 24. In addition, 12 pieces of mesh bodies 24 can be inserted into the mounting portion 25 at the maximum.

被装着部２５に装着するメッシュ体２４の個数を変えることにより、空気の流路における空気抵抗が変えられる。具体的には、各メッシュ体２４は、メッシュ部２４１の枚数に対応した空気抵抗を得ることが可能である。
メッシュ体２４の個数を変えて適切な個数として、呼吸訓練装置１を使用する使用者の呼吸における吸気の能力の程度に適した空気抵抗として、使用者が呼吸訓練装置１を使用して吸気の訓練を行うことが可能である。 By changing the number of mesh bodies 24 mounted to the mounting portion 25, the air resistance in the air flow path can be changed. Specifically, each mesh body 24 can obtain air resistance corresponding to the number of mesh portions 241.

次に、上述した呼吸訓練装置１を用いた、呼吸における吸気の訓練について説明する。呼吸訓練装置１の使用者は、マウスピース４２の開口（口腔側開口４２１）が口に入った状態とし、マウスピース４２の開口から空気を吸気する。これにより、呼吸訓練装置１の外部の空気は、図２において矢印Ａで示すように、流入口２１から流路に入り、被装着部２５に装着されている複数のメッシュ体２４のメッシュ部２４１を通して入口部２０の内部に流入し、活栓３０を通り、フィルタ４１を通り、マウスピース４２の開口（口腔側開口４２１）から使用者の体内に流入する。このとき、メッシュ体２４の個数に応じた空気抵抗が発生し、使用者は、空気抵抗に抗して空気を吸気する。これにより、使用者においては、適度な空気抵抗により、呼吸における吸気の訓練が行われる。   Next, training of inspiration in respiration using the above-described respiratory training apparatus 1 will be described. The user of the breathing training apparatus 1 draws air from the opening of the mouthpiece 42 with the opening of the mouthpiece 42 (oral opening 421) in the mouth. Thereby, the air outside the breathing exercise apparatus 1 enters the flow path from the inflow port 21 as shown by the arrow A in FIG. 2, and the mesh portion 241 of the plurality of mesh bodies 24 mounted on the mounting portion 25. Through the stopcock 30, through the filter 41, and into the user's body from the opening of the mouthpiece 42 (oral opening 421). At this time, air resistance corresponding to the number of mesh bodies 24 is generated, and the user sucks air against the air resistance. In this way, the user is trained in inspiratory breathing with moderate air resistance.

その後、使用者が吸気した空気は、使用者の体内からマウスピース４２の開口を通してマウスピース４２、フィルタ４１を流通し、図２において矢印Ｂで示すように、活栓３０を介して出口部５０を構成する排出口５２を通り、呼吸訓練装置１の外部へ流出する。   Thereafter, the air taken in by the user flows from the user's body through the opening of the mouthpiece 42 and the mouthpiece 42 and the filter 41, and as shown by the arrow B in FIG. It flows out to the exterior of the breathing training apparatus 1 through the discharge port 52 which comprises.

上述の構成による呼吸訓練装置１は、以下のような効果を発揮することができる。   The respiratory training device 1 having the above-described configuration can exhibit the following effects.

For this reason, with the number of mesh bodies 24 being an appropriate number, the user can perform breathing training using the breathing training device 1 as an air resistance suitable for the degree of breathing ability of the user using the breathing training device 1 It is possible to Furthermore, since each mesh body 24 has a predetermined opening ratio, it is possible to obtain air resistance according to the number of mesh bodies 24 mounted on the mounting portion 25.

また、メッシュ体２４は、メッシュ部２４１と、メッシュ部２４１の周囲を取囲む円環状部材２４２と、を有する。被装着部２５は、上方に開口しメッシュ体２４を挿入可能な円弧形状の溝２５１が複数形成された半筒状部材２５０を有する。   Further, the mesh body 24 has a mesh portion 241 and an annular member 242 surrounding the mesh portion 241. The mounting portion 25 has a semi-cylindrical member 250 formed with a plurality of arc-shaped grooves 251 which are opened upward and into which the mesh body 24 can be inserted.

このため、メッシュ体２４の円環状部材２４２のフランジ部付き円筒状部２４４のフランジ部を深溝部２５２に挿入し、円筒状部２４３を浅溝部２５３に挿入することにより、容易にメッシュ体２４を被装着部２５に装着することが可能であり、また、メッシュ体２４の円環状部材２４２のフランジ部付き円筒状部２４４のフランジ部を深溝部２５２から取外し、円筒状部２４３を浅溝部２５３から取り外すことにより、容易にメッシュ体２４を被装着部２５から容易に取り外すことができる。   Therefore, by inserting the flange portion of the flanged cylindrical portion 244 of the annular member 242 of the mesh body 24 into the deep groove portion 252 and inserting the cylindrical portion 243 into the shallow groove portion 253, the mesh body 24 can be easily made. The flange portion of the flanged cylindrical portion 244 of the annular member 242 of the mesh body 24 can be removed from the deep groove portion 252, and the cylindrical portion 243 can be removed from the shallow groove portion 253. By removing it, the mesh body 24 can be easily removed from the mounting portion 25.

また、複数のメッシュ体２４は、互いに当接し合う状態で被装着部２５に装着されて、流路の一部を形成する。このため、流入口２１に最も近い位置に装着されたメッシュ体２４から、流入口２１から最も遠い位置に装着されたメッシュ体２４までは、互いに気密に密着することにより、複数のメッシュ体２４の途中、即ち、隣接するメッシュ体２４間から空気が漏れない空気の流路を構成することができる。このため、被装着部２５の構成を簡単な構成とすることが可能である。   In addition, the plurality of mesh bodies 24 are attached to the mounting portion 25 in a state where they abut each other, and form a part of the flow path. For this reason, the mesh body 24 mounted at a position closest to the inflow port 21 to the mesh body 24 mounted at a position farthest from the inflow port 21 closely adheres to each other airtightly. In the middle, that is, between the adjacent mesh bodies 24, it is possible to configure an air flow path that does not leak air. Therefore, the configuration of the mounting portion 25 can be simplified.

本発明は、上述した実施形態に制限されることなく、請求の範囲に記載した範囲において、様々な形態で実施することができる。例えば、気体流路形成部材、流入口、口腔側開口、排出口、空気抵抗調整機構等の構成は、本実施形態における入口部２０、出口部５０、活栓３０、フィルタ４１、マウスピース４２、弁５１、被装着部２５、メッシュ体２４等の構成に限定されない。従って、例えば、被装着部２５に装着可能なメッシュ体２４の個数は、５個であったが、この個数に限定されない。   The present invention is not limited to the above-described embodiment, and can be implemented in various forms within the scope of the claims. For example, the configurations of the gas flow path forming member, the inlet, the oral cavity opening, the outlet, the air resistance adjusting mechanism, etc. are the inlet 20, the outlet 50, the stopcock 30, the filter 41, the mouthpiece 42, and the valve The configuration is not limited to 51, the mounting portion 25, the mesh body 24, and the like. Therefore, for example, although the number of mesh bodies 24 that can be attached to the mounting portion 25 is five, the number is not limited to this.
