従来から、心臓外科手術等の際に被手術者の人体の心臓を停止させた場合、人体内の血液循環を保ち、人体内に酸素を送るため、人体から送出された血液を溜めるリザーバと、リザーバから受けた血液を送出する血液ポンプと、血液ポンプにより送出された血液につきガス交換等を行なう人工肺とを備える人工心肺装置が知られている（例えば、特許文献１参照。）。
このような人工心肺装置の操作は、被手術者の人体の送血圧（動脈圧）（正常状態で約８０〜１２０ｍｍＨＧ）、中心静脈圧（ＣＶＰ）（正常状態で約５〜８ｍｍＨＧ）、被手術者の人体からの脱血抵抗、被手術者の人体内の血液総量（正常状態で約４〜５リットル）等の各々を、心臓外科手術等の際に一般に用いられる表示装置により表示し、これらの表示を確認しつつ、人工心肺装置の操作者が、血液ポンプにおいて血液を送出する量等を調整する調整ツマミ等の調整手段を操作することにより、送血圧、中心静脈圧、人体内の血液総量等を正常に保つように行なわれていた。
特開２０００−２４５８２９号公報 Conventionally, when the heart of the human body of the operated person is stopped at the time of cardiac surgery or the like, in order to maintain blood circulation in the human body and send oxygen to the human body, a reservoir for storing blood sent from the human body, 2.

しかしながら、従来、人工心肺装置は、実際の心臓外科手術等において人体に付けた状態でのみ使用され、人工心肺装置の操作の練習を行なうことはできず、人工心肺装置の操作者が未熟練の場合、心臓外科手術等の際に、人工心肺装置の操作が正常に行なわれず、送血圧、中心静脈圧、人体内の血液総量等を正常に保てなかったり、人体から送出された血液を溜めるリザーバ内の血液が不足してしまうという恐れがあった。   However, conventionally, the heart-lung machine is used only in a state where it is attached to the human body in actual heart surgery or the like, and the operation of the heart-lung machine cannot be practiced, and the operator of the heart-lung machine is unskilled. In the case of cardiac surgery, the cardiopulmonary apparatus is not normally operated, and blood pressure, central venous pressure, total blood volume in the human body cannot be maintained normally, or blood sent from the human body is collected There was a risk that the blood in the reservoir would run out.

また、従来、人工心肺装置は、実際の心臓外科手術等において人体に付けた状態でのみ使用され、心臓外科手術等に使用する前に、人工心肺装置により正常に血液を循環できるかにつき、人工心肺装置を試用することもできなかったので、実際の心臓外科手術等の前に、人工心肺装置の機能の確認ができなかった。   In addition, conventionally, an artificial cardiopulmonary apparatus is used only in a state where it is attached to a human body in an actual cardiac surgery or the like, and whether or not blood can be normally circulated by an artificial cardiopulmonary apparatus before being used in a cardiac surgery or the like. Since the cardiopulmonary apparatus could not be used, the function of the heart-lung machine could not be confirmed before the actual cardiac surgery.

本発明は、以上のような問題点に鑑みてなされたものであり、人工心肺装置の操作の向上を図ったり、または、人工心肺装置を試用することができる、体外循環用人体シミュレーション装置を提供することを目的とする。   The present invention has been made in view of the above problems, and provides a human body simulation device for extracorporeal circulation that can improve the operation of an oxygenator or can use an oxygenator. The purpose is to do.

以上の目的のため、本発明は、人工心肺装置に連結され、前記人工心肺装置から送出された擬似血液が流れ込むと共に、流れ込んだ擬似血液が人工心肺装置へ向けて送出される、前記人工心肺装置との間で擬似血液が循環される擬似人体部を備えた体外循環用人体シミュレーション装置である。   For the above-mentioned purpose, the present invention is connected to an artificial heart-lung machine, the simulated blood sent from the artificial heart-lung machine flows in, and the flowed simulated blood is delivered to the artificial heart-lung machine It is a human body simulation apparatus for extracorporeal circulation provided with a pseudo human body part in which pseudo blood is circulated between the two.

この発明によれば、人工心肺装置を操作する操作者が、人工心肺装置に人体シミュレーション装置を連結させた状態で人工心肺装置を操作できるので、人工心肺装置の操作の練習を行なって人工心肺装置の操作の向上を図ることができ、または、心臓外科手術等に使用する前に、人工心肺装置を試用することができる。   According to the present invention, an operator who operates the heart-lung machine can operate the heart-lung machine with the human body simulation device connected to the heart-lung machine. In this case, the artificial heart-lung machine can be used before being used for cardiac surgery or the like.

また、本発明において、擬似血液の循環方向における前記人工心肺装置の下流側であって、且つ、前記擬似人体部の上流側に設けられ、前記擬似人体部へ送入される際の擬似血液の擬似血液圧を変更する送入擬似血液圧変更手段を備えていても良い。   Further, in the present invention, the simulated blood is provided at the downstream side of the artificial heart-lung machine in the circulation direction of the simulated blood and the upstream side of the simulated human body part, and when the simulated blood is fed into the simulated human body part. Incoming simulated blood pressure changing means for changing the simulated blood pressure may be provided.

この発明によれば、送入擬似血液圧変更手段により、擬似人体部へ送入させる際の擬似血液の擬似血液圧を変更することができ、この擬似血液圧は、現実の心臓外科手術等における送血圧（動脈圧）に相当するものであるので、擬似人体部へ送入させる擬似血液圧を変更した状態で人工心肺装置の操作を行なって、人工心肺装置の操作の練習を可能とした。そのため、例えば、送入擬似血液圧変更手段により擬似人体部へ送入させる擬似血液圧を変更しても、人工心肺装置、特に、血液ポンプの操作により、擬似人体部へ送入させる擬似血液圧を変更前の状態に戻したり、擬似人体内の擬似血液の総量を所定の目的値にしたり等、現実の心臓外科手術等における送血圧（動脈圧）が変化した場合に対応した人工心肺装置の練習を行なうことができる。   According to the present invention, the simulated blood pressure changing means can change the simulated blood pressure of the simulated blood when it is delivered to the simulated human body part. This simulated blood pressure is used in actual cardiac surgery or the like. Since this corresponds to the blood pressure (arterial pressure), the artificial heart-lung machine was operated with the simulated blood pressure to be transferred to the simulated human body changed, thereby enabling the practice of the artificial heart-lung machine operation. Therefore, for example, even if the simulated blood pressure to be delivered to the simulated human body part is changed by the delivery simulated blood pressure changing means, the simulated blood pressure to be delivered to the simulated human body part by the operation of the oxygenator, particularly the blood pump. Of artificial heart-lung machine corresponding to changes in blood pressure (arterial pressure) in actual cardiac surgery, such as returning to the state before change, or setting the total amount of simulated blood in the simulated human body to a predetermined target value You can practice.

また、本発明において、擬似血液の循環方向における前記擬似人体部の下流側であって、且つ、前記人工心肺装置の上流側に設けられ、前記擬似人体部から送出される際の擬似血液の擬似血液圧を変更する送出擬似血液圧変更手段を備えていても良い。   Further, in the present invention, the simulated blood simulated at the downstream side of the simulated human body part in the simulated blood circulation direction and upstream of the artificial heart-lung machine, and delivered from the simulated human body part. Delivery pseudo blood pressure changing means for changing the blood pressure may be provided.

この発明によれば、送出擬似血液圧変更手段により、擬似人体部から送出される擬似血液圧を変更することができ、この送出擬似血液圧変更手段は、現実の心臓外科手術等における脱血抵抗（人体の下流側に繋がれた人工管等による抵抗であり、この人工管が詰まること等により脱血抵抗が変更する）を変更することに対応するので、擬似人体部から送出される擬似血液圧を変更した状態で人工心肺装置の操作を行なって、人工心肺装置の操作の練習を可能とした。そのため、例えば、送出擬似血液圧変更手段により擬似人体部から送出される擬似血液圧を変更しても、人工心肺装置、特に、血液ポンプの操作により、擬似人体部から送出される擬似血液圧を変更前の状態に戻したり、擬似人体内の擬似血液の総量を所定の目的値にしたり等、現実の心臓外科手術等における脱血抵抗が変化した場合に対応した人工心肺装置の練習を行なうことができる。   According to the present invention, the simulated blood pressure changing means can change the simulated blood pressure delivered from the simulated human body, and the simulated blood pressure changing means can be used for blood removal resistance in actual cardiac surgery or the like. Since it corresponds to changing (the resistance due to the artificial tube connected to the downstream side of the human body and the blood removal resistance is changed due to clogging of the artificial tube, etc.), the simulated blood delivered from the simulated human body part By operating the heart-lung machine with the pressure changed, it was possible to practice the operation of the heart-lung machine. Therefore, for example, even if the simulated blood pressure delivered from the simulated human body part is changed by the delivery simulated blood pressure changing means, the simulated blood pressure delivered from the simulated human body part by the operation of the oxygenator, particularly the blood pump, is changed. Practice the cardiopulmonary apparatus in response to changes in blood removal resistance in actual cardiac surgery, such as returning to the state before the change, or setting the total amount of simulated blood in the simulated human body to a predetermined target value. Can do.

また、本発明において、前記擬似人体部内に収容可能な擬似血液の総量を変更する擬似血液総量変更手段を備えても良い。   In the present invention, a simulated total blood volume changing means for changing the total volume of simulated blood that can be accommodated in the simulated human body part may be provided.

この発明によれば、擬似血液総量変更手段により、擬似人体部内の擬似血液の総量を変更した状態で、人工心肺装置、特に、血液ポンプの操作により、擬似人体内の擬似血液の総量を所定の目的値にする等、人工心肺装置の練習を行なうことができる。また、擬似血液総量変更手段により、擬似人体部内の擬似血液の総量を変更した場合、現実の人体における中心静脈圧（ＣＶＰ）に対応する値も変化するので、現実の心臓外科手術等における中心静脈圧が変化した場合に対応した人工心肺装置の練習を行なうことができる。   According to the present invention, the total amount of simulated blood in the simulated human body is determined by the operation of the artificial cardiopulmonary apparatus, particularly the blood pump, in a state where the total simulated blood volume in the simulated human body is changed by the simulated blood total volume changing means. It is possible to practice an artificial cardiopulmonary apparatus such as setting a target value. Further, when the total amount of simulated blood in the simulated human body is changed by the simulated total blood volume changing means, the value corresponding to the central venous pressure (CVP) in the actual human body also changes. It is possible to practice an artificial heart-lung machine corresponding to a change in pressure.

また、本発明において、前記擬似人体部に接続され、前記擬似人体部から擬似血液を出血させる擬似血液出血手段を備えていても良い。   Moreover, in this invention, you may provide the simulated blood bleeding means connected to the said simulated human body part and bleeding the simulated blood from the said simulated human body part.

この発明によれば、心臓外科手術等の際、被手術者の人体から出血して人体内の血液の総量が減少した場合における、人工心肺装置、特に、血液ポンプの操作の練習をすることができる。   According to the present invention, it is possible to practice the operation of an artificial cardiopulmonary apparatus, particularly a blood pump, when bleeding from the human body of the operated person and the total amount of blood in the human body is reduced during cardiac surgery or the like. it can.

本発明によれば、人工心肺装置を操作する操作者が、人工心肺装置に人体シミュレーション装置を連結させた状態で人工心肺装置を操作できるので、人工心肺装置の操作の練習を行なって人工心肺装置の操作の向上を図ることができ、または、心臓外科手術等に使用する前に、人工心肺装置を試用することができる。   According to the present invention, an operator who operates the heart-lung machine can operate the heart-lung machine in a state where the human body simulation device is connected to the heart-lung machine. In this case, the artificial heart-lung machine can be used before being used for cardiac surgery or the like.

本発明の実施の形態を、以下、図面を参照として説明する。
図１は、本発明の実施の形態による体外循環用人体シミュレーション装置１を示す全体図である。
この体外循環用人体シミュレーション装置１は、人工心肺装置２に連結され、人工心肺装置２との間で、水等の液体である擬似血液がＲ方向に循環するものである。 Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an overall view showing a human body simulation apparatus 1 for extracorporeal circulation according to an embodiment of the present invention.
This extracorporeal circulation human body simulation device 1 is connected to an artificial heart lung device 2, and artificial blood that is a liquid such as water circulates in the R direction between the artificial heart lung device 2.

ここで、本発明の実施の形態による体外循環用人体シミュレーション装置１が連結される人工心肺装置２は、実際の心臓外科手術等で使用されるものと同一のものであり、人体から送出された血液を溜めるリザーバ３と、リザーバ３からの血液を送出する血液ポンプ４と、血液ポンプ４により送出された血液につきガス交換等を行なう人工肺５とを備えている。血液ポンプ４には、調整つまみ（図示を省略）が備えられており、人体（本発明においては人体シミュレーション装置１）へ送出する血液（本発明においては擬似血液）の流量（単位時間当たりの流量）を調整することができる。また、この流量は表示部（図示せず）において表示される。通常、この流量は、４〜５リットル（ｌ）／ｍｉｎとされている。   Here, the cardiopulmonary apparatus 2 to which the extracorporeal circulation human body simulation apparatus 1 according to the embodiment of the present invention is connected is the same as that used in actual cardiac surgery or the like, and is sent from the human body. A reservoir 3 for accumulating blood, a blood pump 4 for delivering blood from the reservoir 3, and an artificial lung 5 for performing gas exchange or the like on the blood delivered by the blood pump 4 are provided. The blood pump 4 is provided with an adjustment knob (not shown), and the flow rate (flow rate per unit time) of blood (pseudo blood in the present invention) to be delivered to the human body (human body simulation apparatus 1 in the present invention). ) Can be adjusted. The flow rate is displayed on a display unit (not shown). Usually, this flow rate is 4 to 5 liters (l) / min.

本発明の実施の形態による体外循環用人体シミュレーション装置１は、人工心肺装置２との間で擬似血液が循環する擬似人体部６と、擬似血液の循環方向における人工心肺装置２の下流側であって、且つ、擬似人体部６の上流側に設けられ、擬似人体部６へ送入させる際の擬似血液の擬似血液圧を変更する送入擬似血液圧変更手段７と、擬似血液の循環方向における擬似人体部６の下流側であって、且つ、人工心肺装置２の上流側に設けられ、擬似人体部６から送出させる際の擬似血液の擬似血液圧を変更する送出擬似血液圧変更手段８と、を備えている。また、擬似人体部６には、擬似人体部６内に収容可能な擬似血液の総量を変更する擬似血液総量変更手段９が設けられ、更に、擬似人体部６には、擬似人体部６から擬似血液を出血させる擬似血液出血手段１０が接続されている。   An extracorporeal circulation human body simulation device 1 according to an embodiment of the present invention includes a simulated human body portion 6 in which simulated blood circulates between the artificial heart lung device 2 and a downstream side of the artificial heart lung device 2 in the circulation direction of the simulated blood. And a simulated blood pressure changing means 7 provided on the upstream side of the simulated human body portion 6 for changing the simulated blood pressure of the simulated blood when the simulated human body portion 6 is fed, and in the simulated blood circulation direction. A delivery simulated blood pressure changing means 8 provided downstream of the simulated human body 6 and upstream of the cardiopulmonary apparatus 2 for changing the simulated blood pressure of simulated blood when delivered from the simulated human body 6; It is equipped with. The simulated human body part 6 is provided with a simulated total blood volume changing means 9 for changing the total amount of simulated blood that can be accommodated in the simulated human body part 6. A simulated blood bleeding means 10 for bleeding blood is connected.

人工心肺装置２と送入擬似血液圧変更手段７との接続、送入擬似血液圧変更手段７と擬似人体部６との接続、擬似人体部６と送出擬似血液圧変更手段８との接続、送出擬似血液圧変更手段８と人工心肺装置２との接続は、夫々、ポリエチレン等の合成樹脂製のチューブ１１により行なわれている。   A connection between the cardiopulmonary apparatus 2 and the delivery simulated blood pressure changing means 7, a connection between the delivery simulated blood pressure changing means 7 and the simulated human body part 6, a connection between the simulated human body part 6 and the delivery simulated blood pressure changing means 8, Connection between the delivery simulated blood pressure changing means 8 and the heart-lung machine 2 is performed by a tube 11 made of a synthetic resin such as polyethylene.

擬似人体部６は、ポリエチレン等の合成樹脂よりなる長方形状の袋体であり、内部が４つの擬似血液収納領域１２に区分されているが、これら４つの擬似血液収納領域１２における隣り合う擬似血液収納領域１２間で擬似血液が自由に移動可能となっている。尚、ここでは、４つの擬似血液収納領域１２に区分されているが、４つ以上に区分されていても、４つ未満に区分されていても良く、また、区分されておらず、１つの擬似血液収納領域１２のみとなっていても良い。   The simulated human body portion 6 is a rectangular bag made of a synthetic resin such as polyethylene, and the inside thereof is divided into four simulated blood storage regions 12, and the adjacent simulated blood in these four simulated blood storage regions 12. The simulated blood can freely move between the storage areas 12. In addition, although it is divided into four pseudo blood storage areas 12 here, it may be divided into four or more, or may be divided into less than four. Only the simulated blood storage area 12 may be provided.

図３に示すように、これら４つの擬似血液収納領域１２の各々には、上方から擬似血液総量変更手段９としての錘を載置できるようになっており、４つの擬似血液収納領域１２の内、いくつの擬似血液収納領域１２に錘を載置したかによって、擬似人体部６内に収容可能な擬似血液の総量が変更される（錘が載置された擬似血液収納領域１２では、錘の重量により擬似血液量が変更される。）。図３では、錘は１つであるが、４つの擬似血液収納領域１２の夫々に対し、最大４つの錘を載置できる。尚、擬似血液総量変更手段９としては、擬似人体部６を縛る紐等、擬似人体部６の容量を変更できれば様々な手段を採用できる。   As shown in FIG. 3, in each of these four simulated blood storage areas 12, a weight as the simulated blood total amount changing means 9 can be placed from above, Depending on how many simulated blood storage areas 12 the weight is placed, the total amount of simulated blood that can be stored in the simulated human body 6 is changed (in the simulated blood storage area 12 on which the weight is placed, The simulated blood volume is changed by weight.) In FIG. 3, the number of weights is one, but a maximum of four weights can be placed on each of the four pseudo blood storage areas 12. Various means can be adopted as the simulated blood total amount changing means 9 as long as the capacity of the simulated human body part 6 can be changed, such as a string for binding the simulated human body part 6.

擬似人体部６内における擬似血液の量は、現実に心臓外科手術等を行なう際の被手術者の人体における血液（循環血液）の量に相当する。また、擬似人体部６内に収容可能な擬似血液の総量に応じて、擬似人体部６内から擬似人体外へ送出される擬似血液圧が変化する（擬似人体部６内で収納可能な擬似血液の総量が多い程、擬似人体部６内から擬似人体外へ送出される擬似血液圧が小さい）。このため、擬似人体部６に錘９を載せることで、擬似人体部６内に送入可能な擬似血液の総量を変化させることは、現実に心臓外科手術等を行なう際の被手術者の人体における中心静脈圧を変化させることにも相当するものである。   The amount of simulated blood in the simulated human body portion 6 corresponds to the amount of blood (circulated blood) in the human body of the operated person when actually performing cardiac surgery or the like. Further, the simulated blood pressure delivered from the simulated human body 6 to the outside of the simulated human body changes according to the total amount of simulated blood that can be stored in the simulated human body 6 (the simulated blood that can be stored in the simulated human body 6). The larger the total amount of the more, the smaller the simulated blood pressure delivered from the simulated human body portion 6 to the outside of the simulated human body). For this reason, by changing the total amount of simulated blood that can be delivered into the simulated human body 6 by placing the weight 9 on the simulated human body 6, the human body of the operator when performing a cardiac surgery or the like actually This is also equivalent to changing the central venous pressure at.

また、擬似人体部６には、擬似人体部６から擬似血液を出血させる擬似血液出血手段１０としての擬似血液出血用チューブが接続されている。擬似血液出血用チューブ１０には、開閉クランプ（図示せず）が設けられており、この開閉クランプの操作により、擬似血液出血用チューブ１０の先端部を開閉して、擬似血液の出血や出血止を行なう。   In addition, a simulated blood bleeding tube as a simulated blood bleeding means 10 for bleeding simulated blood from the simulated human body portion 6 is connected to the simulated human body portion 6. The pseudo blood hemorrhage tube 10 is provided with an open / close clamp (not shown). By operating the open / close clamp, the tip of the pseudo blood hemorrhage tube 10 is opened / closed so that pseudo blood bleeding or bleeding stoppage is achieved. To do.

尚、図示を省略しているが、人体の中心静脈圧に相当する値は、表示器により表示される。   Although not shown, a value corresponding to the central venous pressure of the human body is displayed on the display.

擬似人体部６へ送入する際の擬似血液の擬似血液圧を変更する送入擬似血液圧変更手段７の一端部は、一端部が人工心肺装置２に連結されているチューブ１１の他端部に接続されており、送入擬似血液圧変更手段７の他端部は、一端部が擬似人体部６に連結しているチューブ１１の他端部に接続されている。送入擬似血液圧変更手段７は、途中から４つに分岐する４つの分岐管１４、１５、１６、１７を備えていると共に、４つの分岐管１４、１５、１６、１７は下流側で合流している。また、４つの分岐管１４、１５、１６、１７は夫々異なる径の擬似血液通路を有している。   One end of the simulated blood pressure changing means 7 for changing the simulated blood pressure of the simulated blood when the simulated human body 6 is delivered is the other end of the tube 11 whose one end is connected to the heart-lung machine 2. The other end portion of the delivery simulated blood pressure changing means 7 is connected to the other end portion of the tube 11 whose one end portion is coupled to the simulated human body portion 6. The delivery pseudo blood pressure changing means 7 is provided with four branch pipes 14, 15, 16, and 17 that branch into four from the middle, and the four branch pipes 14, 15, 16, and 17 join downstream. doing. The four branch pipes 14, 15, 16, and 17 have pseudo blood passages having different diameters.

４つの分岐管１４、１５、１６、１７の各々には、開閉クランプ１８、１９が取り付けられており、各々の開閉クランプ１８、１９の操作により、４つの分岐管１４、１５、１６、１７の各々の擬似血液通路が開閉される。従って、４つの分岐管１４、１５、１６、１７に夫々取り付けられた開閉クランプ１８、１９を閉じる数やどの開閉クランプ１８、１９を閉じるかによって、単位時間に送入擬似血液圧変更手段７を通過する擬似血液の流量は変化し、これにより、擬似人体部６へ送入させる際の擬似血液の擬似血液圧を変更することができる。この擬似血液圧の変更が、実際の心臓外科手術等における送血圧（動脈圧）の変化に相当するものである。尚、４つの分岐管１４、１５、１６、１７の全てが開いている状態において、擬似人体部６へ送入させる際の擬似血液の擬似血液圧が最も高く、分岐管１４、１５、１６、１７を閉じる数が多くなるに従って、この擬似血液圧が小さくなるものである。   Opening and closing clamps 18 and 19 are attached to each of the four branch pipes 14, 15, 16, and 17. By operating each of the opening and closing clamps 18 and 19, the four branch pipes 14, 15, 16, and 17 are attached. Each simulated blood passage is opened and closed. Therefore, depending on the number of closing clamps 18, 19 attached to the four branch pipes 14, 15, 16, and 17, and the opening / closing clamps 18, 19, the simulated blood pressure changing means 7 is changed in unit time. The flow rate of the simulated blood passing therethrough is changed, whereby the simulated blood pressure of the simulated blood when being fed into the simulated human body part 6 can be changed. This change in pseudo blood pressure corresponds to a change in blood pressure (arterial pressure) in actual cardiac surgery or the like. In addition, in the state where all of the four branch pipes 14, 15, 16, 17 are open, the simulated blood pressure of the pseudo blood when being fed into the simulated human body part 6 is the highest, and the branch pipes 14, 15, 16, This pseudo blood pressure decreases as the number of closing 17 increases.

また、開閉クランプ１７、１８としては、図２（ａ）に示すような先端部が鋭角状の係合部１９を、鋸刃状に多段階に設けられている係合受部２０におけるどの位置に係合させるかによって、分岐管１４の通路を通過する擬似血液の流量を変化できる多段階式開閉クランプ（多段階式流量調整具）１７の他、図２（ｂ）に示すような先端部が鋭角状の係合部１９を単一の係合受部２１に係合させるか否かのみを切り替えられるオンオフ式開閉クランプ１８の双方を使用可能である。   Further, as the open / close clamps 17 and 18, an engagement portion 19 having an acute-angled tip as shown in FIG. 2A is arranged at any position in the engagement receiving portion 20 provided in multiple stages in a saw blade shape. 2 (b) as well as a multi-stage open / close clamp (multi-stage flow regulator) 17 that can change the flow rate of the pseudo blood passing through the passage of the branch pipe 14 depending on whether it is engaged with It is possible to use both of the on-off type open / close clamp 18 that can be switched only whether or not the engagement portion 19 having an acute angle is engaged with the single engagement receiving portion 21.

また、送入擬似血液圧変更手段７としては、４つの分岐管１４、１５、１６、１７によるものではなく、例えば、２つの分岐管や８つの分岐管によるものなど、様々使用可能である。また、分岐管によるものではなく、１本の管の開口面積を調整するダイヤル式（アナログ式）の調整弁により、アナログ式で通過する擬似血液の流量を変化できるようにしても良い。   In addition, the delivery simulated blood pressure changing means 7 is not limited to the four branch pipes 14, 15, 16, and 17, but can be used in various ways, for example, using two branch pipes or eight branch pipes. Further, instead of using a branch pipe, a dial-type (analog type) adjustment valve that adjusts the opening area of one pipe may be used to change the flow rate of pseudo blood passing through the analog type.

尚、図示を省略しているが、擬似人体部６内に送入される際の擬似血液の擬似血圧（人体の送血圧に相当する）は、表示器により表示される。   Although not shown, simulated blood pressure of pseudo blood (corresponding to blood pressure of the human body) when being fed into the simulated human body 6 is displayed on the display.

擬似人体部６から送出される擬似血液の擬似血液圧を変更する送出擬似血液圧変更手段８の一端部は、一端部が擬似人体部６に連結されているチューブ１１の他端部に接続されており、送出擬似血液圧変更手段８の他端部は、一端部が人工心肺装置２に連結しているチューブ１１の他端部に接続されている。   One end of the delivery simulated blood pressure changing means 8 for changing the simulated blood pressure of the simulated blood delivered from the simulated human body 6 is connected to the other end of the tube 11 whose one end is connected to the simulated human body 6. The other end portion of the delivery simulated blood pressure changing means 8 is connected to the other end portion of the tube 11 connected to the oxygenator 2 at one end portion.

送出擬似血液圧変更手段８としては、本実施形態では、送入擬似血液圧変更手段７と同一の部材が使用されている。
即ち、送出擬似血液圧変更手段８は、途中から４つに分岐する４つの分岐管２２、２３、２４、２５を備えていると共に、４つの分岐管２２、２３、２４、２５は下流側で合流している。また、４つの分岐管２２、２３、２４、２５は夫々異なる径の擬似血液通路を有している。 As the delivery simulated blood pressure changing means 8, in this embodiment, the same member as the delivery simulated blood pressure changing means 7 is used.
That is, the delivery simulated blood pressure changing means 8 includes four branch pipes 22, 23, 24, and 25 that branch into four from the middle, and the four branch pipes 22, 23, 24, and 25 are arranged on the downstream side. Have joined. The four branch pipes 22, 23, 24, and 25 have pseudo blood passages having different diameters.

４つの分岐管２２、２３、２４、２５の各々には、開閉クランプ２６、２７が取り付けられており、各々の開閉クランプ２６、２７の操作により、４つの分岐管２２、２３、２４、２５の各々の擬似血液通路が開閉される。従って、４つの分岐管２２、２３、２４、２５に夫々取り付けられた開閉クランプ２６、２７を閉じる数やどの開閉クランプ２６、２７を閉じるかによって、単位時間に送出擬似血液圧変更手段８を通過する擬似血液の流量は変化し、これにより、擬似血液を擬似人体部６から送出させる際の擬似血液の擬似血液圧を変更することができる。この擬似血液圧の変更が、実際の心臓外科手術等における、人体外における脱血抵抗の値の変化に相当するものである。尚、４つの分岐管２２、２３、２４、２５の全てが開いている状態において、脱血抵抗値に相当する値が最も低く、分岐管２２、２３、２４、２５を閉じる数が多くなるに従って、この値が大きくなるものである。   Open / close clamps 26 and 27 are attached to each of the four branch pipes 22, 23, 24, and 25. By operating each of the open / close clamps 26 and 27, the four branch pipes 22, 23, 24, and 25 are connected. Each simulated blood passage is opened and closed. Therefore, depending on the number of closing clamps 26, 27 attached to the four branch pipes 22, 23, 24, 25, respectively, and the opening / closing clamps 26, 27, the simulated blood pressure changing means 8 passes through the delivery time per unit time. The flow rate of the simulated blood changes, so that the simulated blood pressure of the simulated blood when the simulated blood is delivered from the simulated human body 6 can be changed. This change in the pseudo blood pressure corresponds to a change in the value of blood removal resistance outside the human body in actual cardiac surgery or the like. In the state where all of the four branch pipes 22, 23, 24, 25 are open, the value corresponding to the blood removal resistance value is the lowest, and as the number of closing the branch pipes 22, 23, 24, 25 increases. This value becomes larger.

また、開閉クランプとしては、係合部２８を、多段階に設けられている係合受部２９におけるどの位置に係合させるかによって、分岐管２２の通路を通過する擬似血液の流量を変化できる多段階式開閉クランプ（多段階式流量調整具）２６の他、係合部２８を係合受部３０に係合させるか否かのみを切り替えられるオンオフ式開閉クランプ２７の双方を使用可能である。尚、多段階式開閉クランプ２６、オンオフ式開閉クランプ２７としては、図２におけるものと同様のものを採用可能である。   Further, as the open / close clamp, the flow rate of the pseudo blood passing through the passage of the branch tube 22 can be changed depending on which position in the engagement receiving portion 29 provided in multiple stages the engagement portion 28 is engaged with. In addition to the multistage open / close clamp (multistage flow rate adjusting tool) 26, it is possible to use both an on / off open / close clamp 27 that can switch only whether or not the engaging portion 28 is engaged with the engagement receiving portion 30. . As the multi-stage open / close clamp 26 and the on / off open / close clamp 27, those similar to those shown in FIG. 2 can be employed.

また、送出擬似血液圧変更手段８としては、４つの分岐管２２、２３、２４、２５によるものではなく、例えば、２つの分岐管や８つの分岐管によるものなど、様々使用可能である。また、分岐管によるものではなく、ダイヤル式（アナログ式）の調整弁により、アナログ式で通過する擬似血液の流量を変化できるようにしても良い。
尚、図示を省略しているが、脱血抵抗に相当する値は、表示器により表示される。 The delivery simulated blood pressure changing means 8 is not limited to the four branch pipes 22, 23, 24, 25, but can be variously used, for example, two branch pipes or eight branch pipes. Further, instead of using a branch pipe, the flow rate of the pseudo blood passing in an analog manner may be changed by a dial type (analog type) regulating valve.
Although not shown, the value corresponding to the blood removal resistance is displayed on the display.
