Further, the viscosity and temperature of the simulated blood are also measured by a sensor (not shown) and sent to the computer 7.

  The input device 4 is connected to the blood pump 33 via the control device 5, and the control device 5 drives the blood pump 33 based on the operation information input to the input device 4 by the operator 9. Circulate blood. Further, the input device 4 is also connected to the computer 7 so that the computer 7 can calculate simulation information based on operation information input by the operator 9, for example, information on an assumed patient (gender, height, weight, cardiac coefficient, etc.). I am doing so. For information that has not been input, initial setting values are automatically set.

なお、例えば下部で断面積が小さくなっている貯血槽のように、槽高により断面積が変化するような複雑な形状の貯血槽を使用する場合には、時刻ｔにおける貯血槽の水位ｈ（ｔ）と、貯血槽液量Ｖ_Ｒ‐Ｈ（ｈ（ｔ））との関係を校正曲線として与えることで、貯血槽の底面圧Ｐ_３（ｔ）から数式（２）および数式（３）を用いて貯血槽液量Ｖ_Ｒ（Ｐ_３（ｔ））を算出することができる。

また、時刻ｔにおける送血流量Ｑ_Ａは、模擬血液温度Ｔ、模擬血液粘度η、実験定数λを用いて人工肺入口圧Ｐ_１（ｔ）および人工肺出口圧Ｐ_２（ｔ）から数式（４）を用いて算出することができる。

更に、時刻ｔにおける脱血流量Ｑ_Ｖは、微小時間を△ｔとして送血流量Ｑ_Ａ、貯血槽液量Ｖ_Ｒ（Ｐ_３（ｔ））、時刻ｔより微小時間△ｔ前の貯血槽液量Ｖ_Ｒ（Ｐ_３（ｔ‐△ｔ））から数式（５）を用いて算出することができる。

Here, in general, the calculation of the blood reservoir volume V _R (P ₃ (t)) at time t is performed using, for example, the density ρ of the simulated blood, the gravitational acceleration g, and the bottom area A of the blood reservoir 32, and the bottom surface of the blood reservoir. from pressure _P 3 (t) can be calculated using equation (1).

For example, when using a blood reservoir having a complicated shape whose cross-sectional area changes depending on the tank height, such as a blood reservoir having a small cross-sectional area at the bottom, the water level h ( and t), by giving the calibration curve the relationship between the blood reservoir fluid volume _{V R-H (h (t} )), formula from base pressure _P 3 of the blood reservoir (t) (2) and equation (3) The blood reservoir volume V _R (P ₃ (t)) can be calculated.

Further, the blood flow rate Q _{A at} time t is calculated from the artificial lung inlet pressure P ₁ (t) and the artificial lung outlet pressure P ₂ (t) using the simulated blood temperature T, simulated blood viscosity η, and experimental constant λ. 4).

Further, the blood removal rate Q _{V at} time t is a blood flow rate Q _A , blood reservoir fluid amount V _R (P ₃ (t)) with a micro time as Δt, and blood reservoir fluid before micro time Δt from time t. It can be calculated from the quantity V _R (P ₃ (t−Δt)) using the formula (5).

  With the configuration as described above, as shown in FIG. 3, according to the extracorporeal circulation device 3 of the present embodiment, the operator 9 inputs operation information (S1), and drives the blood pump 33 to generate simulated blood. Circulating (S2), sensors such as pressure sensors 61 to 63 measure physical information generated by the circulation (S3), performing simulation based on the physical information and operation information (S4), and displaying the simulation result (S5). Thus, the extracorporeal circulation technique can be trained using simulation.

  According to such an extracorporeal circulation device 3, unlike the conventional training device as shown in FIG. 4, simulation is performed without providing the training device 1 with a flow sensor 10 for measuring the blood flow removal rate and the blood flow rate. It can be used for repetitive training of basic operations of extracorporeal circulation. Further, since there is no need to provide the flow sensor 10, there is no need for error correction by using a soft circuit in the simulated blood circuit, and the response characteristics of the sensor when determining the quality of the extracorporeal circulation operation are eliminated. There is no problem. Therefore, it is possible to reduce the cost and size of the training apparatus 1 for the extracorporeal circulation apparatus, and to provide the training apparatus 1 that is easy to introduce and maintain and highly portable.

  Moreover, according to the training apparatus 1, since it is possible to calculate the simulation information by calculating the blood flow removal rate and the blood flow delivery rate simply by providing a pressure sensor, “For extracorporeal circulation education” established by the Japanese Society for Extracorporeal Circulation Technology. It is possible to use it as a standard equipment in sensors (such as pressure sensors at the oxygenator inlet and manometers at the oxygenator outlet), as well as existing cardiopulmonary circuits and pressure transducer training equipment held in hospital facilities. The cost of introducing and maintaining the training device 1 can be further reduced.

  As a modified example of the above-described embodiment of the present invention, a predetermined scenario or event is input to the training device 1 via the input device 4, and the simulation information considering this is calculated in real time. You may do it. In this case, the simulation (S4) based on the physical information and operation information shown in FIG. 3 is calculated in consideration of the scenario or event. The scenario or event is input manually by an operator 9 or a leader (not shown) or automatically by a computer.

  Here is an example of an event or scenario: “After starting extracorporeal circulation, if the blood removal volume is small but the blood delivery volume is large, the blood level in the cardiopulmonary apparatus will drop rapidly and the level sensor will sound. A screen is displayed to warn the trainee to reduce the amount of blood to be delivered or to reduce the amount of blood to be removed, and a voice instruction is given from a speaker (not shown). After that, if the level of extracorporeal circulation is too low, an alarm (not shown) notifies the danger of sending air, and a simulation is made that the blood pump 33 automatically stops. Various situations that can occur in actual medical practice can be input as events and scenarios.

  If configured as such a modified example, the training device for extracorporeal circulation devices that can reproduce real trouble cases in line with the clinical field also eliminates the need for the installation of a flow sensor and reduces cost and size. Can be realized. Also, if training is performed by giving instructions to the operator according to a predetermined scenario, the training can be performed without a leader.

  In addition to the above-described embodiments and modifications, the training device for an extracorporeal circulation device of the present invention may measure the pressure difference between the inlet and the outlet of the oxygenator using a differential pressure gauge. In this way, it is not necessary to separately provide pressure sensors at the inlet and outlet of the oxygenator, and a more compact training device can be provided. In addition to the measurement using a pressure sensor, the simulated blood volume in the blood reservoir may be measured using a level meter or the like, and the simulated blood volume in the blood reservoir can be measured directly with the level meter. For example, the labor for calculating the simulated blood volume in the blood reservoir can be saved. Further, the physical information and the operation information are not limited to the above-described information, and various types of information can be used for simulation. In addition, the circuit configuration of the blood removal means and the extracorporeal circulation device can be arbitrarily changed according to the training purpose.

  Thus, according to the training apparatus for an extracorporeal circulation apparatus of the present invention, the blood flow volume and blood removal volume during the operation training are simulated between the simulated blood volume (blood storage volume) in the blood reservoir and the inlet and outlet of the artificial lung. Since it is calculated (indirect measurement) using the pressure difference (differential pressure) of the simulated blood and used for calculation of simulation information, it is not necessary to provide a flow sensor for measuring the blood flow rate and the blood flow rate. In addition, since there is no need to provide a flow sensor, there is no need for error correction by using a soft circuit for the simulated blood circuit, and there is a problem with the response characteristics of the sensor when determining the quality of the extracorporeal circulation operation. It will never be. Therefore, it is possible to reduce the cost and size of the training device for the extracorporeal circulation device, and to provide a training device that is easy to introduce and maintain and highly portable.

  According to the program of the present invention, the computer controls the measurement unit to measure the blood storage amount and the pressure difference (differential pressure) of the simulated blood between the inlet and the outlet of the artificial lung, and based on the measured value Since the blood flow and blood flow during operation training can be calculated and simulation information can be calculated using the calculated blood flow and blood flow, the blood flow and blood flow are measured. The program which can implement | achieve the training method for extracorporeal circulation apparatuses which do not need to provide the flow sensor for this can be provided. Further, since the flow rate is obtained by calculation without being measured by the flow sensor, it is not necessary to include an additional step related to error correction and sensor response characteristic problems in the program. Therefore, it is possible to provide a program that allows a computer to execute a low-cost and compact training method for an extracorporeal circulation device.
