Abstract
Description
心肺蘇生では適切な深さで胸骨圧迫を行うことが重要である。本発明は、適切な深さの胸骨圧迫を行うためにどれくらいの力加減で圧迫すればよいのかを身につけるのに有用な心肺蘇生マネキンと、それを用いた心肺蘇生トレーニング方法に関する。In cardiopulmonary resuscitation, it is important to perform chest compressions at an appropriate depth. The present invention relates to a cardiopulmonary resuscitation mannequin useful for learning how much force should be applied to perform chest compressions of an appropriate depth, and a cardiopulmonary resuscitation training method using the same.
心肺蘇生時には、５ｃｍの深さで胸骨圧迫することで傷病者の予後が改善することが科学的に証明されており、非特許文献１の通り心肺蘇生のガイドラインでも５ｃｍの深さで胸骨圧迫をすることが推奨されている。It has been scientifically proven that chest compressions at a depth of 5 cm improve the prognosis of the victim during cardiopulmonary resuscitation. It is recommended to do.
そのため、加速度センサーを用いて心肺蘇生中に胸骨圧迫の深さを正確に測る圧迫深度測定装置も臨床応用されてはいるが、使用場所は救急車内などに限られており、一般的に蘇生現場で使用されることはない。多くの救助者は自分の胸骨圧迫の深さを正確に知るのは困難であり、自分が加える力の感覚を頼りに胸骨圧迫を行う。Therefore, a compression depth measuring device that accurately measures the depth of sternum compression during cardiopulmonary resuscitation using an accelerometer has also been clinically applied, but its use is limited to ambulances, etc., and is generally used at resuscitation sites. Never used in. Many rescuers have difficulty knowing exactly how deep their chest compressions are, and rely on their sense of force to perform chest compressions.
心肺蘇生のスキルを身につけるためには、胸骨圧迫の深さを測定できる心肺蘇生マネキンを用い、５ｃｍの深さで胸骨を圧迫する訓練を通じて、胸骨圧迫に必要な力加減を学んでいる。しかし、心肺蘇生マネキンの胸郭の硬さは製造会社によってばらつきがあることが非特許文献２の通り報告されている。また、多くの心肺蘇生マネキンはスプリングを用いており、胸骨圧迫に要する力と胸骨圧迫の深さは線形的である。しかし、非特許文献３の遺体による報告によると、ヒトの胸骨圧迫に要する力と胸骨圧迫の深さは線形的ではない。実際の傷病者とは違う硬さや性質を持つ心肺蘇生マネキンで５ｃｍの深さで圧迫する訓練を積んでスキルを身につけても、実際の傷病者を対象に適切な心肺蘇生ができるとは限らないという問題があった。In order to acquire cardiopulmonary resuscitation skills, a cardiopulmonary resuscitation mannequin that can measure the depth of chest compressions is used, and through training to compress the sternum at a depth of 5 cm, the force required for chest compressions is learned. However, it has been reported as described in Non-Patent Document 2 that the hardness of the thorax of a cardiopulmonary resuscitation mannequin varies depending on the manufacturer. Also, many CPR mannequins use springs, and the force required for chest compressions and the depth of chest compressions are linear. However, according to the report by the body of Non-Patent Document 3, the force required for sternum compression and the depth of sternum compression in humans are not linear. Even if you acquire the skills by training to press at a depth of 5 cm with a cardiopulmonary resuscitation mannequin that has different hardness and properties from the actual victim, it is not always possible to perform appropriate cardiopulmonary resuscitation for the actual victim. There was a problem that there was no.
本発明は、従来における前記問題を解決するため、実際の傷病者と同様の硬さや性質を持つ心肺蘇生マネキンを作成し、それと胸骨圧迫の深さを正確に測る圧迫深度測定装置を併用して、５ｃｍの深さで胸骨圧迫するトレーニングを提供することを目的とする。In the present invention, in order to solve the above-mentioned problems in the past, a cardiopulmonary resuscitation mannequin having the same hardness and properties as an actual victim is prepared, and the cardiopulmonary resuscitation mannequin is used in combination with a compression depth measuring device for accurately measuring the depth of chest compressions. It is intended to provide chest compression training at a depth of 5 cm.
前記課題を解決するための心肺蘇生マネキンは、胸骨圧迫の深さとそれに要する力の関係が、非特許文献３の遺体による報告のとおり、ヒトと同じような非線形の関係になるようにする。 The cardiopulmonary resuscitation mannequin for solving the above-mentioned problems makes the relationship between the depth of chest compressions and the force required for the chest compressions a non-linear relationship similar to that of humans, as reported by the corpse of Non-Patent Document 3.
そのために、心肺蘇生マネキン内部にはバネ係数と長さの異なる複数のスプリングを同心円状に配置する。すべてのスプリングは心肺蘇生マネキンの底面と接するように固定し、一番長いスプリングは胸板を介して心肺蘇生マネキンの胸部と接するように配置する。Therefore, a plurality of springs having different spring coefficients and lengths are concentrically arranged inside the cardiopulmonary resuscitation mannequin. All springs should be fixed in contact with the bottom of the CPR mannequin, and the longest spring should be placed in contact with the chest of the CPR mannequin via the chest plate.
心肺蘇生マネキンの胸骨圧迫を行うと、まず１番長いスプリングが圧縮され、圧迫長に比例して弾性力が生じる。そして２番目に長いスプリングと同じ長さになった段階から、圧迫には２つのバネの弾性力に抗する力が必要になってくる。このように、適切なバネ係数と長さの異なる複数のスプリング組み合わせることにより、胸骨圧迫に要する力と胸骨圧迫の深さの関係を、非線形のヒトに近づけることが可能となる。When chest compressions are performed on a cardiopulmonary resuscitation mannequin, the longest spring is first compressed, and an elastic force is generated in proportion to the compression length. Then, from the stage when the length becomes the same as that of the second longest spring, the compression requires a force that opposes the elastic force of the two springs. In this way, by combining a plurality of springs having appropriate spring constants and different lengths, it is possible to bring the relationship between the force required for chest compressions and the depth of chest compressions closer to that of a non-linear human.
前記心肺蘇生マネキンに、市販されている胸骨圧迫の深さを正確に測る圧迫深度測定装置を併用して、５ｃｍの深さで胸骨圧迫するトレーニングをおこなう。The cardiopulmonary resuscitation mannequin is used in combination with a commercially available compression depth measuring device that accurately measures the depth of chest compressions, and training is performed to compress the sternum at a depth of 5 cm.
胸骨圧迫の深さを正確に測る圧迫深度測定装置を用いながら、本発明によるリアリティーの高い心肺蘇生マネキンでトレーニングを行うことにより、実際の臨床で傷病者の予後を改善する５ｃｍの深さの胸骨圧迫に、どれくらいの力加減が必要かを身につけることができる。A 5 cm deep sternum that improves the prognosis of the victim by training with the highly realistic cardiopulmonary resuscitation mannequin according to the present invention while using a compression depth measuring device that accurately measures the depth of chest compressions. You can learn how much force is required for compression.
本発明の心肺蘇生マネキンの一例を示す図１を参照する。心肺蘇生心肺蘇生マネキン内部にはバネ係数と長さの異なる複数のスプリングを同心円状に配置する。すべてのスプリングは心肺蘇生マネキンの底面と接するように固定し、一番長いスプリングは胸板を介して心肺蘇生マネキンの胸部と接するように配置する。市販されている胸骨圧迫の深さを正確に測る圧迫深度測定装置をマネキン前胸部の圧迫部位に配置して胸骨圧迫を行う。心肺蘇生マネキンの胸骨圧迫を行うと、まず１番長いスプリングが圧縮され、圧迫長に比例して弾性力が生じる。そして１番目のスプリングが２番目に長いスプリングと同じ長さになった段階から、圧迫には２つのスプリングの弾性力に抗する力が必要になってくる。このように、適切なバネ係数と長さの異なる複数のスプリング組み合わせることにより、胸骨圧迫に要する力と胸骨圧迫の深さの関係を、非線形のヒトに近づけることが可能となる。See FIG. 1, which shows an example of a cardiopulmonary resuscitation mannequin of the present invention. Cardiopulmonary resuscitation Inside the cardiopulmonary resuscitation mannequin, multiple springs with different spring coefficients and lengths are arranged concentrically. All springs should be fixed in contact with the bottom of the CPR mannequin, and the longest spring should be placed in contact with the chest of the CPR mannequin via the chest plate. A commercially available compression depth measuring device that accurately measures the depth of chest compressions is placed at the compression site on the anterior chest of the mannequin to perform chest compressions. When chest compressions are performed on a cardiopulmonary resuscitation mannequin, the longest spring is first compressed, and an elastic force is generated in proportion to the compression length. Then, from the stage when the first spring has the same length as the second longest spring, the compression requires a force that opposes the elastic force of the two springs. In this way, by combining a plurality of springs having appropriate spring constants and different lengths, it is possible to bring the relationship between the force required for chest compressions and the depth of chest compressions closer to that of a non-linear human.
本発明の心肺蘇生マネキンに配置するスプリングの組み合わせの一例を示す図２を参照する。一番長いスプリング（スプリング１）の長さをＬｍｍとする。次に長いスプリング（スプリング２）を（Ｌ−２０）ｍｍ、その次に長いスプリング（スプリング３）を（Ｌ−４０）ｍｍとし、それぞれのバネ係数を５００ｇｆ／ｍｍｍ、５００ｇｆ／ｍｍｍ、１０００ｇｆ／ｍｍとする。図２では３個のスプリングの組み合わせを例示したが、スプリングの数を増やすこともできる。See FIG. 2, which shows an example of a combination of springs placed on the cardiopulmonary resuscitation mannequin of the present invention. The length of the longest spring (spring 1) is L mm. The next longest spring (spring 2) is (L-20) mm, the next longest spring (spring 3) is (L-40) mm, and the spring constants are 500 gf / mmm, 500 gf / mmm, and 1000 gf / mm, respectively. And. Although the combination of three springs is illustrated in FIG. 2, the number of springs can be increased.
図３は、スプリングを図２のように組み合わせた場合の、胸骨圧迫の深さとそれに要した力の関係をグラフに示したものである。グラフは非特許文献３のヒトのデータと重ね合わせて示している。ヒトでの胸骨圧迫の深さとそれに要した力の関係は非線形であるが、３個のスプリングを組み合わせることにより、ヒトの胸骨圧迫の深さとそれに要した力との関係に近づくことがわかる。スプリングの数を増やしてその長さやバネ係数を適切に設定することで、胸骨圧迫の深さとそれに要した力の関係はより滑らかになり、更にヒトのデータに近づけることができる。 FIG. 3 is a graph showing the relationship between the depth of sternum compression and the force required for the combination of the springs as shown in FIG. The graph is shown superimposed on the human data of Non-Patent Document 3. The relationship between the depth of sternum compression in humans and the force required for it is non-linear, but it can be seen that the combination of the three springs brings the relationship between the depth of sternum compression in humans and the force required for it closer. By increasing the number of springs and setting their lengths and spring constants appropriately, the relationship between the depth of sternum compression and the force required for it becomes smoother and can be closer to human data.
本発明の心肺蘇生マネキンは、心肺蘇生法のトレーニングに利用できる。本発明の心肺蘇生マネキンはヒトと同様の胸郭の硬さや性質を備えているため、このマネキンを用いたトレーニングで習得したスキルは、実際の傷病者を対象とした心肺蘇生現場でもそのまま役に立つ。The cardiopulmonary resuscitation mannequin of the present invention can be used for training in CPR. Since the cardiopulmonary resuscitation mannequin of the present invention has the same hardness and properties of the thorax as humans, the skills acquired by training using this mannequin are directly useful in the field of cardiopulmonary resuscitation for actual victims.
