Description

本発明は、心臓震盪の発症を抑止する目的で胸部に装着される心臓保護具に関するものである。   The present invention relates to a cardiac protector worn on the chest for the purpose of suppressing the onset of cardiac concussion.

近年、心臓への衝撃により心停止に至る心臓震盪という症状が注目されている。これは、衝撃により肋骨や胸骨が折れたり心臓の筋肉が損傷したりするなどの物理的障害により発症するのではなく、衝撃による心室細動という心臓の機能的障害により衝撃力の強弱にあまり関係なく発症することが知られている。   In recent years, attention has been paid to the symptom of cardiac concussion that leads to cardiac arrest due to shock to the heart. This is not caused by a physical disorder such as the rib or sternum being broken or the heart muscle being damaged by the impact, but it is not related to the strength of the impact force due to the functional disorder of the heart such as ventricular fibrillation due to the impact. It is known that it will develop without any symptoms.

これまで、このような心臓震盪の発症を抑止することを目的とした心臓保護具は皆無であるが、例えば、野球又はソフトボールのキャッチャー用身体保護具(例えば、プロテクタやレガーツ)の構造を採用する、すなわち、少なくとも衝撃吸収対象となる胸部の心臓直上部の全面を当て付け対象とするウレタンなどの軟質の衝撃吸収材の外側に硬質プロテクタを積層接着して心臓保護具を構成することで、硬質プロテクタによる衝撃力の拡散作用と、衝撃吸収材による衝撃力の吸収作用とによって、心臓直上部への単位面積当たりの衝撃力を低減する程度のことは容易に想像できる。   Until now, there has been no cardioprotective device for the purpose of suppressing the occurrence of such heart concussion, but for example, the structure of a bodyguard for baseball or softball catchers (eg, protector or legato) has been adopted. In other words, by constructing a heart protector by laminating and bonding a hard protector on the outside of a soft shock absorber such as urethane to apply at least the entire surface immediately above the heart of the chest to be shock absorbed, It can be easily imagined that the impact force per unit area directly above the heart is reduced by the impact force diffusion action by the hard protector and the impact force absorption action by the shock absorber.

しかし、キャッチャー用身体保護具の構造を採用する上記の如き心臓保護具のように、
単位面積当たりの衝撃力を低減するだけでは、衝撃力の強弱にあまり関係なく発症する心臓震盪の抑止に十分とはいえない。
However, like the above-mentioned cardiac protector that employs the structure of a body protector for catchers,
Simply reducing the impact force per unit area is not sufficient to suppress cardiac concussion that occurs regardless of the strength of the impact force.

また、単位面積当たりの衝撃力の低減効果を一層向上させるために、衝撃吸収材や硬質プロテクタの質量を大きくすれば、保護具全体としての質量や重量が大きくなって、着用者の動作に支障を来たしたり、着用時間が制限されたりするなどの虞もある。   In addition, in order to further improve the effect of reducing the impact force per unit area, if the mass of the shock absorber or hard protector is increased, the mass and weight of the protective equipment as a whole will increase, impairing the wearer's operation. There is also a risk that the wear time will be limited.

この実情に鑑み、本発明の主たる課題は、装着時の着用者への影響を極力小さなものとしながらも、衝撃による心臓震盪の発症を効果的に抑止することのできる心臓保護具を提供する点にある。   In view of this situation, the main problem of the present invention is to provide a heart protector capable of effectively suppressing the onset of cardiac concussion due to impact while minimizing the influence on the wearer at the time of wearing. It is in.

本発明の第1特徴構成は心臓保護具に係り、その特徴は、
少なくとも心臓直上部を被覆する状態で胸部に装着される心臓保護具であって、
胸部に対する当て付け部は、受止衝撃力を心臓直上部よりも心臓直上部から外れた部位へ直接的に伝達する状態で、心臓直上部から外れた部位を当て付け対象とする構成にし、
胸部の心臓直上部に対向配置される心臓直上部対向部位としての中央部位が、その側方の外縁部位よりも胸側とは反対側に位置する凸形状にするとともに、側面輪郭形状について、最も胸側とは反対側に位置する凸形状頂点部位が縦方向中心線よりも腹側に位置する形状に形成して、凸形状頂点部位より首側の首側方部分における凸形状頂点部位への上り傾斜が、凸形状頂点部位より腹側の腹側方部分における凸形状頂点部位への上り傾斜よりも緩やかになるようにしてある点にある。
A first characteristic configuration of the present invention relates to a cardiac protector,
A cardioprotective device worn on the chest while covering at least the upper part of the heart,
The abutting part for the chest is a state in which the receiving impact force is transmitted directly to the part off the heart directly above the heart, and the part that is off the heart is applied .
The central part as the part directly opposite to the heart that is placed directly above the heart of the chest is a convex shape that is located on the opposite side of the chest side from the lateral outer edge part, and A convex apex part located on the side opposite to the chest side is formed in a shape located on the ventral side of the longitudinal center line, and the convex apex part in the neck side part on the neck side from the convex shape apex part is formed. The ascending slope is set to be gentler than the ascending slope toward the convex apex portion in the ventral side portion on the ventral side of the convex apex portion .

つまり、上記第1特徴構成であれば、胸部の心臓直上部から外れた部位を当て付け対象とする当て付け部を通じて、受止衝撃力を心臓直上部よりも心臓直上部から外れた部位へ直接的に伝達するから、質量や重量を特に増大することなしに、心臓直上部に伝達される衝撃力、或いは、心臓直上部に衝撃力が伝達される確率を効果的に低減することができ、これにより、装着時の着用者への影響を極力小さなものとしながらも心臓震盪の発症を効果的に抑止することができる。   In other words, with the first feature configuration, the receiving impact force is directly applied to the part off the heart directly above the heart directly through the abutting part to which the part off the heart directly above the chest is applied. Therefore, it is possible to effectively reduce the probability of the impact force being transmitted directly above the heart or the impact force being transmitted directly above the heart without particularly increasing the mass and weight. Thereby, the onset of cardiac concussion can be effectively suppressed while minimizing the influence on the wearer at the time of wearing.

本発明の第2特徴構成は、第1特徴構成の実施に好適な実施形態を特定するものであり、その特徴は、
胸部の心臓直上部に対向する心臓直上部対向部位の胸側に空間が形成される構成にしてある点にある。
The second feature configuration of the present invention specifies an embodiment suitable for the implementation of the first feature configuration.
The point is that a space is formed on the chest side of the portion directly opposite to the heart directly opposite the heart of the chest.

つまり、上記第2特徴構成であれば、受止衝撃力により心臓直上部対向部位が胸側に変形ないし変位した場合でも、その心臓直上部対向部位の胸側に形成された空間の分だけ心臓直上部対向部位が心臓直上部に接触するのを抑止することができ、これにより、心臓直上部に伝達される衝撃力、或いは、心臓直上部に衝撃力が伝達される確率を一層効果的に低減することができる。   In other words, with the second feature configuration, even if the portion directly opposite to the heart is deformed or displaced to the chest side due to the receiving impact force, the heart is as much as the space formed on the chest side of the portion immediately opposite to the heart. It is possible to prevent the directly opposite portion from coming into contact with the upper part of the heart, thereby more effectively increasing the probability of the impact force being transmitted directly above the heart or the impact force being transmitted directly above the heart. Can be reduced.

本発明の第3特徴構成は、第2特徴構成の実施に好適な実施形態を特定するものであり、その特徴は、
前記空間には、軟質の充填材を嵌装してある点にある。
The third feature configuration of the present invention specifies an embodiment suitable for the implementation of the second feature configuration.
In the space, a soft filler is fitted.

つまり、上記第3特徴構成であれば、例えば、受止衝撃力により心臓直上部対向部位が破損した場合でも、軟質の充填材が胸部の保護材となって心臓直上部対向部位の破片で胸部が傷着くことを抑止することができるとともに、充填材と心臓直上部との接触により生じる摩擦抵抗によって、心臓直上部に対する心臓直上部対向部位の位置ズレを効果的に抑止することができるから、その心臓直上部対向部位の位置ズレにより、心臓直上部に伝達される衝撃力の低減効果、或いは、心臓直上部に衝撃力が伝達される確率の低減効果が損なわれるなどの不具合を効果的に抑止することができる。   In other words, with the third feature configuration, for example, even when the site directly above the heart is damaged by the receiving impact force, the soft filling material serves as a protective material for the chest and the chest is broken by a fragment at the site directly above the heart. Since the frictional resistance generated by the contact between the filler and the upper part of the heart can effectively suppress the positional shift of the part directly opposite the heart with respect to the upper part of the heart. Effectively eliminates the effect of reducing the impact force transmitted directly above the heart or reducing the probability that the impact force is transmitted directly above the heart due to the positional deviation of the portion directly above the heart. Can be deterred.

本発明の第4特徴構成は、第1〜第3特徴構成の実施に好適な実施形態を特定するものであり、その特徴は、
前記当て付け部の当て付け面を軟質の衝撃吸収材で構成してある点にある。
The fourth feature configuration of the present invention specifies an embodiment suitable for the implementation of the first to third feature configurations.
The abutting surface of the abutting portion is composed of a soft shock absorber.

つまり、上記第4特徴構成であれば、受止衝撃力の一部を当て付け部で吸収することができるから、その吸収分だけ心臓直上部対向部位に加わる衝撃力を低減することができ、これにより、心臓直上部に伝達される衝撃力、或いは、心臓直上部に衝撃力が伝達される確率を一層効果的に低減することができる。   That is, with the fourth feature configuration, a part of the receiving impact force can be absorbed by the abutting portion, so that the impact force applied to the portion directly opposite to the heart can be reduced by that amount of absorption, As a result, it is possible to more effectively reduce the impact force transmitted directly above the heart or the probability that the impact force is transmitted directly above the heart.

[第1実施形態]
図1〜図3は、球技時の心臓への衝撃による心臓震盪の発症を抑止する目的で、少なくとも心臓直上部Aを被覆する状態で胸部に装着される心臓保護具の一例である球技用心臓保護具1を示し、この球技用心臓保護具1は、比較的硬質の合成樹脂(本例では、ポリカーボネイド)からなる保護具本体2の胸側(すなわち、内側)に、受止衝撃力(すなわち、球技時に外方から保護具本体2に加わる衝撃力)を胸部の心臓直上部Aよりも心臓直上部Aから外れた部位Bへ直接的に伝達する状態で、心臓直上部Aから外れた部位Bを当て付け対象とする当て付け部3を構成してある。
[First Embodiment]
FIGS. 1 to 3 show an example of a heart for a ball game, which is an example of a heart protector worn on the chest in a state of covering at least the heart directly A for the purpose of suppressing the onset of cardiac concussion due to an impact on the heart during ball game The protector 1 is shown, and the ball protector 1 for ball games has a receiving impact force (i.e., on the chest side (i.e., inside) of the protector body 2 made of a relatively hard synthetic resin (polycarbonate in this example). In the state where the impact force applied to the protective equipment body 2 from the outside during ball game is transmitted directly to the part B off the heart directly above the heart A directly above the heart A above the part of the chest, An abutting section 3 that is subject to B is configured.

前記保護具本体2は、装着時に胸部の心臓直上部Aに対向配置される心臓直上部対向部位としての中央部位2Aが、その側方の外縁部位2Bよりも胸側とは反対側に位置する凸形状、詳しくは、正面輪郭形状が円形状で、且つ、側面輪郭形状が略半球面形状のドーム型形状に構成してあり、外方からの衝撃力の一部を球面傾斜に沿って受け流すとともに中央部位2Aの内側に空間Sが形成される構成にしてある。   The protective device main body 2 has a central portion 2A as a portion directly opposite to the heart that is disposed opposite to the portion directly above the heart A of the chest at the time of wearing, and is located on the opposite side of the chest from the outer edge portion 2B on the side. Convex shape, more specifically, a dome shape with a circular front profile and a substantially hemispherical side profile, and receives a part of the impact force from the outside along the spherical slope. In addition, the space S is formed inside the central portion 2A.

また、保護具本体2の外縁部位2Bの端縁には、心臓直上部2Aの直径よりも若干大なる直径の内側開口を備えるリング状の突出片3Aを断面視中央向き略くの字状に屈曲する形態で一体成形するとともに、その突出片3Aの胸側面には、突出片3Aとほぼ同一形状の軟質材料(本例では、EVA)からなる衝撃吸収材3Bを接着接合してあり、これら突出片3Aと衝撃吸収材3Bとをもって、前記当て付け部3を構成してある。   In addition, a ring-shaped protruding piece 3A having an inner opening with a diameter slightly larger than the diameter of the portion 2A immediately above the heart is formed in a substantially U-shape toward the center in a sectional view at the edge of the outer edge portion 2B of the protective device body 2. These are integrally molded in a bent form, and a shock absorbing material 3B made of a soft material (EVA in this example) having substantially the same shape as the protruding piece 3A is adhesively bonded to the chest side surface of the protruding piece 3A. The abutting portion 3 is constituted by the protruding piece 3A and the shock absorbing material 3B.

つまり、当て付け部3は、本例では、胸部の心臓直上部Aから外れた部位として心臓直上部Aの外周囲部Bのみを当て付け対象とする構成にしてあり、受止衝撃力を心臓直上部Aの外周囲部Bに伝達することで、質量や重量を特に増大することなしに心臓直上部Aへの衝撃力の伝達を防止し、これにより、装着時の着用者への影響を極力小さなものとしながらも心臓震盪の発症を効果的に抑止する。   That is, in this example, the abutting portion 3 is configured to apply only the outer peripheral portion B of the upper portion A of the heart as a portion removed from the upper portion A of the heart of the chest, and the receiving impact force is applied to the heart. By transmitting to the outer peripheral part B of the upper part A, the transmission of the impact force to the upper part A of the heart is prevented without particularly increasing the mass and weight, thereby preventing the influence on the wearer at the time of wearing. Effectively deters the onset of cardiac concussion while making it as small as possible.

また、衝撃吸収材3Bの胸側面を当て付け面とすることで、受止衝撃力の一部を衝撃吸収材3Bで吸収するようにしてある。   Moreover, a part of the receiving impact force is absorbed by the shock absorbing material 3B by using the chest side surface of the shock absorbing material 3B as an abutment surface.

前記保護具本体2の側面輪郭形状について、さらに詳しく説明すると、最も胸側とは反対側に位置する凸形状頂点部位2aが縦方向中心線Cよりも腹側方(すなわち、下方)に位置する形状に形成してあり、凸形状頂点部位2aが縦方向中心線Cやそれよりも首側方(すなわち、上方)に位置する場合に比して、凸形状頂点部位2aから首側方の首側方部分の縦方向長さを長く確保して、その首側方部分の傾斜(つまり、凸形状頂点部位への上り傾斜)が緩やかになるようにしてある。 The side surface contour shape of the protective device main body 2 will be described in more detail. The convex apex portion 2a located on the most opposite side to the chest side is located on the abdominal side (that is, below) the longitudinal center line C. Compared to the case where the convex vertex portion 2a is positioned in the longitudinal direction center line C or on the neck side side (that is, the upper side) than the longitudinal center line C, the neck from the convex shape vertex portion 2a to the neck side is formed. The longitudinal length of the side portion is ensured to be long, and the inclination of the neck side portion (that is, the upward inclination to the convex apex portion) is made gentle.

前記空間Sの胸側深さDは、球技時の衝撃による保護具本体2の中央部位2Aの胸側変位深さdよりも大なる深さで形成してあり、これにより、外方からの衝撃による中央部位2Aの変位によって保護具本体2と心臓直上部Aとが接触するのを防止する。   The chest side depth D of the space S is formed with a depth larger than the chest side displacement depth d of the central portion 2A of the protective equipment body 2 due to impact during ball game, and from this, It is prevented that the protector main body 2 and the upper part A of the heart come into contact with each other due to the displacement of the central part 2A due to the impact.

なお、例えば、硬式野球と軟式野球とでは衝撃発生対象となるボールの硬さが相違するために衝撃値が異なるなど、球技時の衝撃値は球技種によって異なるものであるから、前記空間Sの深さDは、球技種や衝撃発生対象(ボールやバット)、或いは、保護具本体2の硬さ、変位量などに応じて適宜設定すればよい。   In addition, for example, the impact value at the time of ball game is different depending on the type of ball game, such as the impact value is different because the hardness of the ball to be impacted is different between the hard baseball and the soft baseball. The depth D may be appropriately set according to the ball game type, the impact generation target (ball or bat), the hardness of the protector main body 2, the amount of displacement, and the like.

前記保護具本体2における正面直径寸法Rは、12cm未満では心臓直上部Aに直接的に衝撃が伝達されてしまう虞があるし、反対に25cmよりも大きいと動作種によって腕が保護具本体2に触れてプレーに支障を来たしてしまうことから、12cm〜25cmの範囲が好適であり、本例では、約20cmの直径寸法で形成してある。   If the front diameter dimension R of the protector main body 2 is less than 12 cm, there is a possibility that an impact is directly transmitted to the upper part A of the heart. The range of 12 cm to 25 cm is suitable because it interferes with play by touching, and in this example, it is formed with a diameter of about 20 cm.

また、保護具本体2の凸形状頂点部位2aの頂点高さHは、8mm〜30mmの範囲(さらに好ましくは、8mm〜15mmの範囲)が好適であり、本例では、約15mmの高さ寸法で形成してある。   Further, the apex height H of the convex apex portion 2a of the protective device body 2 is preferably in the range of 8 mm to 30 mm (more preferably in the range of 8 mm to 15 mm), and in this example, the height dimension is about 15 mm. It is formed with.

図3は、球技用シャツの一例である伸縮性素材からなる野球用のアンダーシャツ5を示し、このアンダーシャツ5の胸相当部、詳しくは心臓相当箇所には、前記球技用心臓保護具1を挿脱可能なポケット部6をアンダーシャツ5と同一素材で形成してある。   FIG. 3 shows a baseball undershirt 5 made of a stretchable material, which is an example of a ball game shirt. The ball game heart protector 1 is placed on the chest equivalent portion of the undershirt 5, more specifically on the heart equivalent portion. The removable pocket portion 6 is formed of the same material as the undershirt 5.

前記ポケット部6は、球技用心臓保護具1の正面直径寸法Rよりも若干小さな横寸法で、且つ、正面直径寸法Rよりも若干大きな縦寸法で形成するとともに、その首側方(すなわち、上方)に球技用心臓保護具1の挿入口6aを形成する構成にしてある。   The pocket portion 6 has a lateral dimension slightly smaller than the front diameter dimension R of the ball game heart protector 1 and a vertical dimension slightly larger than the front diameter dimension R, and the side of the neck (that is, the upper side) ) To form the insertion port 6a of the ball game heart protector 1.

前記挿入口6aの上端部には、挿入口6aを被覆閉塞可能な垂片状蓋6bを取り付けてある。この垂片状蓋6bの内側面とこれに相対向するポケット部6の外側面には、対をなす雄雌の面ファスナ6cの一方づつを夫々配設してあり、これら面ファスナー6cどうしの噛合によりポケット部6を閉塞保持できるようにしてある。   A drooping lid 6b that can cover and close the insertion port 6a is attached to the upper end of the insertion port 6a. A pair of male and female hook-and-loop fasteners 6c are disposed on the inner side surface of the lid-like lid 6b and the outer side surface of the pocket portion 6 opposite to this, respectively. The pocket portion 6 can be closed and held by meshing.

つまり、球技用心臓保護具1をポケット部6の挿入口6aを通してポケット部6を伸張させながら挿入したのちに、垂片状蓋6bとポケット部6の外側面の面ファスナー6cどうしを噛合せて挿入口6aを閉塞する(図3(イ)〜(ロ))ことにより、アンダーシャツ5に対する球技用心臓保護具1の位置がしっかり保持された状態で球技用心臓保護具1をアンダーシャツ5に取り付けることができる。   That is, after the ball game heart protector 1 is inserted while the pocket portion 6 is extended through the insertion opening 6a of the pocket portion 6, the drooping lid 6b and the surface fastener 6c on the outer surface of the pocket portion 6 are engaged with each other. By closing the insertion port 6a (FIGS. 3 (a) to 3 (b)), the ball game heart protector 1 is attached to the under shirt 5 in a state where the position of the ball game heart protector 1 with respect to the under shirt 5 is firmly held. Can be attached.

そして、球技者は、このアンダーシャツ5を着用することによって、別の専用取付具を用いることなく、球技用心臓保護具1が心臓直上部Aを確実に被覆する状態で球技用心臓保護具1を容易且つ確実に身軽な状態で装着することができる。   Then, the ball player wears the undershirt 5 so that the ball protector 1 for the ball game covers the portion A immediately above the heart without using a separate dedicated fixture. Can be attached easily and reliably in a light state.

また、休憩時や洗濯時など心臓に対する保護を必要としないときには、垂片状蓋6bとポケット部6の外側面の面ファスナー6cどうしの噛合を解いて挿入口6aを開口したのちに、球技用心臓保護具1を挿入口6aを通じてポケット部6から抜き出すことで、アンダーシャツ5から球技用心臓保護具1を容易に取り外すことができる。   Also, when protection against the heart is not required, such as during breaks or washing, after opening the insertion slot 6a by releasing the engagement between the hook-shaped lid 6b and the hook-and-loop fastener 6c on the outer surface of the pocket portion 6, The cardioprotective heart protector 1 can be easily removed from the undershirt 5 by pulling out the heart protector 1 from the pocket 6 through the insertion opening 6a.

[第2実施形態]
前述の実施形態では、保護具本体2を、正面輪郭形状が円形状で、且つ、側面輪郭形状が略半球面状のドーム型形状に構成していたが、この実施形態では、図4、図5に示すように、保護具本体2を、正面輪郭形状が円形状で、且つ、側面輪郭形状が胸部側とは反対側に階段状に突出する形状のドーム型形状に構成してある。
[Second Embodiment]
In the above-described embodiment, the protective device main body 2 is configured in a dome shape having a circular front shape and a substantially hemispherical side surface shape. In this embodiment, FIG. As shown in FIG. 5, the protective device main body 2 is configured in a dome shape having a circular front profile and a side profile protruding stepwise on the opposite side of the chest.

前記保護具本体2の側面輪郭形状について詳しく説明すると、環状の蹴上げ相当面部2dが胸直交方向に沿う形態で凸形状頂点部位2aに向けて上下両側から階段状に突出する形状としてあり、外方からの衝撃力に対する被衝撃部位としての中央部位2Aの体積を極力大きく確保して、単位体積当たりの衝撃力を低減するとともに、外方からの衝撃力の荷重向きに略等しい蹴上げ相当面部2dが衝撃力に対する抵抗体となって蹴上げ相当面部2dの分だけ中央部位2Aの衝撃力に対する変形量を低減する。   The side contour shape of the protective device main body 2 will be described in detail. The annular kick-up equivalent surface portion 2d has a shape that protrudes stepwise from the upper and lower sides toward the convex apex portion 2a in a form along the chest orthogonal direction. The central portion 2A as an impacted portion with respect to the impact force from the center is secured as large as possible to reduce the impact force per unit volume, and the kick equivalent surface portion 2d is substantially equal to the load direction of the impact force from the outside. It becomes a resistor against the impact force and reduces the deformation amount with respect to the impact force of the central portion 2A by the amount corresponding to the kick-up equivalent surface portion 2d.

前記保護具本体2の蹴上げ相当面部2dにおいて、保護具本体2の縦方向中心線Cよりも首方側に位置する複数箇所には、装着時に中央部位2Aの内側に形成される空間Sの内外を連通する上向き開口の通気孔4を形成してある。   In the kick-up equivalent surface portion 2d of the protector main body 2, a plurality of positions located on the neck side with respect to the longitudinal center line C of the protector main body 2 are provided inside and outside the space S formed inside the central portion 2A when worn. A vent hole 4 having an upward opening that communicates with each other is formed.

つまり、この複数の通気孔4を通じて空間S内部の換気を効果的に図るとともに、大きな衝撃力を受けたときに中央部位2Aの内側への急激な変形により生じる通気孔への空気押込圧によって通気孔4に隣接する部分の破壊を誘発する。   That is, the inside of the space S is effectively ventilated through the plurality of vent holes 4, and the air is pressed by the air pushing pressure to the vent holes caused by the sudden deformation inward of the central portion 2A when receiving a large impact force. It induces destruction of the part adjacent to the pores 4.

なお、その他の構成は第1実施形態で説明した内容と同一であるから、同一の構成箇所には同一の番号を付してその説明は省略する。   In addition, since the other structure is the same as the content demonstrated in 1st Embodiment, the same number is attached | subjected to the same structure location, and the description is abbreviate | omitted.

[別実施形態]
次に本発明の別実施形態を列記する。
前述の各実施形態では、心臓保護具として球技用心臓保護具を例に示したが、球技用に限らず、格闘技など球技以外のスポーツ用心臓保護具であってもよく、また、日常的に装着される心臓保護具であってもよい。
[Another embodiment]
Next, other embodiments of the present invention will be listed.
In each of the above-described embodiments, a cardioplegic cardioprotective device has been shown as an example of a cardioprotective device. It may be an attached cardioprotective device.

前述の各実施形態では、胸部に対する当て付け部3は、心臓直上部から外れた部位(心臓直上部周囲部B)のみを当て付け対象とすることで、受止衝撃力を心臓直上部Aよりも心臓直上部から外れた部位へ直接的に伝達する構成にしていたが、例えば、当て付け部3は、心臓直上部Aよりも心臓直上部から外れた部位を面積的に広く当て付け対象とする構成にしたり、また、受止衝撃力の重心位置が心臓直上部から外れた部位に位置する状態で心臓直上部Aと心臓直上部から外れた部位の両方を当て付け対象とする構成にしたり、或いは、これらを組み合わせて構成したりするなどのことで、受止衝撃力を心臓直上部Aよりも心臓直上部から外れた部位へ直接的に伝達する構成にしてもよい。   In each of the above-described embodiments, the abutting portion 3 for the chest is intended to be applied only to a portion (periphery portion B immediately above the heart) that is removed from the portion immediately above the heart, so that the receiving impact force is greater than the portion A directly above the heart. However, for example, the abutting unit 3 is configured to apply a site that is distant from the region directly above the heart more than the region A directly above the heart. Or a configuration in which both the part directly off the heart A and the part off the heart are applied in a state where the center of gravity position of the receiving impact force is off the part directly above the heart. Alternatively, the receiving impact force may be directly transmitted to a part off the upper part of the heart rather than the upper part A of the heart by, for example, combining them.

前述の各実施形態では、球技用シャツとしてアンダーシャツ5を例に示したが、例えば、ユニフォームなどであってもよい。   In each of the above-described embodiments, the undershirt 5 is shown as an example of a ball game shirt, but it may be a uniform, for example.

前述の各実施形態では、球技用シャツ(アンダーシャツ5)に球技用心臓保護具1を挿脱可能なポケット部6を形成していたが、例えば、球技用シャツの胸部形成材の内部に球技用心臓保護具1を埋設固定するなどにより、球技用心臓保護具1と球技用シャツとを一体化してもよい。   In each of the above-described embodiments, the pocket portion 6 into which the ball protection device 1 can be inserted and removed is formed in the ball game shirt (undershirt 5).
