Description

  The present invention relates to a training device for an extracorporeal circulation device, and more particularly to a training device for an extracorporeal circulation device in which a flow control valve is provided in a blood circuit.

  In open heart surgery for severe heart disease, the reliability of the extracorporeal circulation device is very important, and the skill of the medical staff operating it is also demanded. Therefore, in order to acquire and maintain the skills of clinical engineering engineers engaged in the operation of life support management devices such as extracorporeal circulation devices, the importance of extracorporeal circulation technology education in accordance with clinical practice is increasing. Many such extracorporeal circulation devices have been put into practical use, and the inventor of the present application has also developed an artificial lung device (see Patent Document 1) related to the extracorporeal circulation device. The clinical engineering engineer's practical guidance on extracorporeal circulation technology mainly consists of understanding the structure centering on assembly and preparation of the device and on-site practical guidance starting with a clinical site visit in hospital training.

  On the other hand, automation of the extracorporeal circulation device is being promoted, and it is important to learn how to deal with troubles with automation, but there are few opportunities to encounter these troubles at the clinical site, time and cases The actual situation is that sufficient practical training is not possible in the limited number of clinical training sessions. There are also reports of the worst results during extracorporeal circulation due to the inability to deal with such troubles. From this point of view, training by simulation of an extracorporeal circulation device that reproduces an unexpected trouble and quickly copes with it is important. Some clinical engineering engineer training schools are working on the construction of simulation software and simulation equipment for on-campus training. However, these conventional simulation softwares all emphasize the assembly procedure of the extracorporeal circulation device, the understanding of the principle and structure, and the simulation device for promptly responding to various situations occurring in the clinical field And it was not possible to become simulation software.

Furthermore, the operation of such a heart-lung machine requires an instantaneous response to complicated circulatory dynamics, and if one step is mistaken, it leads to a serious medical accident. Accordingly, the inventors of the present application have developed a “device capable of performing a simulation operation training by controlling a heart-lung machine connected to a human body simulation circuit by a personal computer” (see Patent Document 2).
Japanese Unexamined Patent Publication No. 06-000219 (paragraphs 0008-0011, FIG. 1) Japanese Patent Laying-Open No. 2005-114764 (paragraphs 0005-0006, FIG. 1)

  With the above-described simulation apparatus according to the prior art, it is possible to perform simulation training on how to deal with an accident that may occur during driving together with the normal driving operation of the heart-lung machine. In such cardiopulmonary operation, the blood flow rate and blood pressure mainly depend on the flow rate control and blood flow control of the blood pump, and the flow rate control and blood flow control of the pump are the main operation targets. It is.

However, when an extracorporeal circulation device is used clinically, changes in blood flow and blood pressure that do not depend on, or hardly depend on, the flow rate control of the pump may occur. That is, clogged blood vessels and blood vessels (cannulas), defects in each blood circuit and flow path on the device side, problems on the surgical field and the human body (eg, physical conditions such as bleeding in blood vessels and organs such as veins and arteries) Unexpected changes in blood flow and blood pressure may occur due to various factors such as the above, and the conventional training apparatus described above trains how to deal with situations involving troubles that do not depend on such pump control. It was difficult. In other words, it has not been possible to carry out a training that accurately simulates the state of trouble that may be caused by such a clogged state with a blood circuit or a cannula or cause such a clogged state.
Then, an object of this invention is to provide the training apparatus for extracorporeal circulation apparatuses which can reproduce the more realistic trouble example which solved the various problems mentioned above.

In order to solve the above-described problems, a training apparatus for an extracorporeal circulation apparatus according to the first invention is provided.

According to the present invention, the real-time numerical simulation unit can input an event by a user such as a leader or a trainee from the input unit, or an automatic event input by a computer (pathological change, increase / decrease in blood loss, increase / decrease in blood pressure) (Changes in heart rate, arrhythmia, rise and fall in body temperature, accidents, etc.), or select from a plurality of scenarios (situations in which the events occur in time series) stored in advance in the storage device (instructors) Or manually selected by a trainee or automatically selected by a computer), and the simulation biological information is calculated in real time by taking this into account. According to the present invention, the scenario occurs during extracorporeal circulation. Various events and scenarios during extracorporeal circulation such as blood pressure fluctuations can be simulated. Furthermore, it is possible to learn also remedy of complications.

A training device for an extracorporeal circulation device according to the third invention is
The blood circuit provided with the flow control valve is a blood removal circuit, a vent circuit (a circuit that receives blood from a part of the heart), a blood supply circuit, and a surgical part suction circuit (suction of bleeding in the surgical field with a suction pump) A circuit that receives and flows into the blood reservoir),

According to the present invention, each part, for example, a blood removal circuit or a blood transmission circuit and a cannula such as a blood removal blood vessel or a blood supply blood vessel connected thereto, or a defect or an abnormality of a vein or artery of the connection destination is detected. Since it can be reproduced realistically, more realistic and clinical training can be performed. In addition, since the degree of opening of the multiple flow control valves in these blood circuits and flow paths can be set freely, complex abnormalities and defects caused by these parts can be reproduced and trained more realistically. it can. Each blood circuit and each flow path can be provided with one or more. For example, there are usually two blood removal circuits, and the valves of the first and second blood removal circuits are individually controlled to remove blood. Training that reproduces problems such as circuit bending can be performed. Similarly, when a valve is provided in the flow path of the simulated circulation unit, troubles and abnormalities on the human body side can be realistically reproduced, so that more realistic and clinical training can be performed.

Become. Moreover, the obtained physical information can also be reflected in the valve opening degree of each valve. If the blood flow rate and blood pressure cannot be reproduced even after adjusting to a specific valve opening to reproduce the blood flow and blood pressure of the desired trouble example, the physical information measured by this configuration is fed back to the valve opening. This makes it possible to perform training that accurately reproduces the blood flow rate and blood pressure of a desired trouble example. For example, if the blood flow rate decreases, the blood in the heart becomes insufficient and the vent cannula is likely to be blocked. However, such a blood flow sensing result is reflected in the opening degree of the vent circuit flow control valve. If the valve opening degree of the vent circuit is reduced, it is possible to carry out training that faithfully reproduces the phenomenon.

The
As described above, the solving means of the present invention has been described as an apparatus. However, the present invention can be realized as a method, a program, and a storage medium that records the program substantially, and the scope of the present invention. It should be understood that these are also included.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a basic configuration of a training apparatus for an extracorporeal circulation apparatus according to the present invention. As shown in the figure, the training apparatus 100 according to the present invention presents an input unit 110, a simulated circulation unit 120, a simulation unit 130, a storage unit (hard disk, flash memory, etc.) 140, and an information presentation unit (speech, video, characters, etc.). Device 150) and an extracorporeal circulation device 160. The simulated circulation unit 120 includes a flow path 122 for flowing simulated blood and a measurement unit 124. The training apparatus 100 includes a blood sending circuit 161, a blood removal circuit 162, a vent circuit 163, and a surgical part suction circuit 164. Each blood circuit is provided with flow control valves (proportional control solenoid valves) V1, V2, V3, and V4. Although not shown, each blood circuit is also provided with a flow sensor and a blood pressure sensor. The valve opening can be set in steps such as 10 steps and 100 steps, and the simulation unit 130 can calculate the valve opening according to a specific event or scenario. The measuring unit 124 includes not only a flow rate sensor and a blood pressure sensor but also a thermometer and other sensors.

  The input unit 110 inputs operation information related to blood circulation. As operation information, a valve opening, an assumed weight, a blood pressure before extracorporeal circulation, a heart rate, and a body temperature are input. After that, when extracorporeal circulation is started, blood removal volume, blood flow volume, pump flow rate, blood cooling temperature, reservoir tank fluid volume, reservoir tank negative pressure, etc. are input, and blood pressure, peripheral Simulation values of blood vessel resistance and blood temperature are output. Default values are automatically set for information that has not been entered. The control unit 115 transmits, to the extracorporeal circulation apparatus 160, a control signal for controlling the extracorporeal circulation apparatus 160 so as to circulate the simulated blood while adjusting each valve opening degree, for example, based on operation information including the valve opening degree. The extracorporeal circulation device 160 sends simulated blood to the simulated circulation unit 120 based on this control signal. Moreover, the valve opening degree of each flow volume electromagnetic valve V1-V4 is adjusted based on a control signal. The simulated circulation unit 120 is configured to simulate hemodynamics of a living body (human, animal, etc.) such as vein compliance. That is, the simulated circulation unit 120 receives simulated blood (liquid having various characteristics such as viscosity and temperature similar to living body blood) sent from the extracorporeal circulation device 160, and the simulated blood is a flow channel imitating a blood vessel. The simulated blood is finally returned to the extracorporeal circulation device 160. The simulated blood circulates in the flow path 122, and the measurement unit 124 measures physical information generated by the circulation of the simulated blood. The measurement unit 124 of the simulated circulation unit 120 includes a flow rate sensor, a blood pressure sensor, a temperature sensor, and the like, and physical information measured there is a blood supply amount, a blood removal amount, a temperature, a blood pressure, and the like.

The real-time numerical simulation unit 130 performs real-time simulation biological information including at least hemodynamic information based on the operation information, the physical information measured by the simulated circulation unit, and the liquid amount, flow rate sensor, and blood pressure sensor in each blood circuit. calculate. The information presentation unit 150 presents the calculated simulated biological information to an operator (training participant). Note that the operator (user) can not only receive training directly in the system 100 but also access the system 100 from a user PC or the like via a network such as the Internet and receive training. Similarly, the instructor can not only directly access the system 100 but also access the system 100 from a communication terminal or the like via a network. Input data, measured data, calculated data, and the like are stored in the storage unit 140.
The real-time numerical simulation unit 130 receives an event input by an instructor or a scenario selected from a plurality of scenarios prepared in advance, and calculates simulation biological information in real time in consideration of the scenario.

  FIG. 2 is an example of a flowchart of the training method according to the present invention. As shown in the figure, in step S110, the instructor or the operator inputs operation information including information such as valve opening using the operation console of the extracorporeal ring device, and the information is an electric signal as a real-time numerical simulation unit. Sent to. In step S115, the extracorporeal circulation unit flows simulated blood to the simulated circulation unit based on the operation information input from the operation console. In S120, physical information (blood supply amount, blood removal amount, temperature, etc.) generated by this blood circulation is measured, and the measurement result is converted into a digital value by an A / D converter and transmitted to the real-time numerical simulation unit. . In S130, the instructor (or operator) selects an event or scenario that simulates a disease state change, an accident, or the like with respect to the real-time numerical simulation unit. In S140, an event input or a selected scenario is received, and this is also taken into consideration to calculate simulation biometric information in real time. In S150, the operator performs an appropriate operation by visually recognizing a change in biological information due to the user's own operation and the occurrence of an event on the information presentation display. Depending on the stage of training, it is possible to select training using only the operation console and the real-time numerical simulation device, or training using an actual extracorporeal circulation device. In addition, by using a predetermined program in the real-time numerical simulation apparatus as a substitute for the instructor, it is possible to perform repetitive training only by the operator.

Here, the details of the above-described simulation algorithm will be described. The input information is the assumed weight, heart rate, blood pressure, and body temperature of the patient before extracorporeal circulation. After starting extracorporeal circulation, when blood flow, blood removal (ml / min), and target body temperature (usually lower target body temperature) are entered, the remaining blood volume in the pump and the patient's cardiac output are adjusted accordingly. Each value such as quantity, heart rate, blood pressure, and body temperature is simulated and displayed. After injecting myocardial protective fluid (ml / min) after blocking the aorta, cardiac arrest occurs, and then the blood pressure and vascular resistance in the simulation include the blood flow of the extracorporeal circulation, the valve opening provided at various locations, etc. Depends on. By subtracting the blood removal volume from the total circulating blood volume added with the injected myocardial protective fluid volume, the blood volume in the blood vessel in the living body is calculated by simulation, and the blood pressure, perfusion rate, and the like are displayed.
Each biometric information value simulated in the present invention has a mutual dependency. For example, blood pressure is roughly determined by peripheral vascular resistance and cardiac output factors as in the following equations.
Blood pressure = coefficient x (cardiac output x peripheral vascular resistance)

Conversely, if blood pressure and cardiac output are known, peripheral vascular resistance can be determined by simulation. In addition to the above, in the blood pressure, the circulating blood volume, central venous pressure, blood viscosity, blood vessel wall elasticity (that is, the cross-sectional area of the flow path is changed by increasing or decreasing the blood vessel tension, and the circulating blood volume is changed. ) Etc. are also relevant. Furthermore, the cardiac output depends on the heart rate, the single cardiac output, and the body surface area (convertible from the assumed body weight).
Therefore, the device according to the present invention is based on the input operation information, the physical information measured by the simulated circulation unit, the default value, and the like, using the above formulas and the like such as blood pressure, peripheral vascular resistance, and cardiac output. The biometric information value can be obtained by simulation.

Here, some examples of an event input by a user or a computer or a scenario stored in advance in a storage device will be given.
Example scenario 1
By adjusting the valve opening degree of the “blood removal circuit”, poor blood removal caused by the surgical field such as bending of the blood removal circuit or abnormal position of the blood removal cannula can be reproduced.
Scenario example 2
By adjusting the valve opening of the “vent circuit”, it is possible to reproduce the blockage of the vent circuit due to sticking of the tip of the vent cannula due to the lack of blood in the heart chamber.
Example scenario 3
By adjusting the valve opening degree of the “blood transmission circuit”, it is possible to reproduce the aortic dissection caused by the surgical field side, the abnormal insertion position, the increase in blood pressure due to the bending of the circuit, or the insufficient amount of blood.
Scenario example 4
By using two blood removal circuits, one-sided blood removal abnormality and two-sided blood removal abnormality can be arbitrarily generated, and different coping methods can be learned.
Scenario example 5
By adjusting the valve opening of the flow path (for example, an artery or vein), it is possible to reproduce the peripheral vascular resistance and peripheral vascular bed on the human body side, abnormalities due to bleeding, abnormalities due to air inhalation, and abnormalities due to incomplete aortic blockade.
Example scenario 6
After extracorporeal circulation, if the blood removal volume is low but the blood supply volume is high, the blood level in the cardiopulmonary apparatus will drop rapidly and the level sensor will sound to reduce the blood supply volume or reduce the blood removal volume Alert trainers to do In response to this, the trainee inputs operation information appropriately. Then, if the level of extracorporeal circulation decreases too much, an alarm notifies the danger of sending air, and the operation of the pump automatically simulating is simulated.
Example scenario 7
After the cardiac surgery is completed, the aortic block is released, and after the self-beating is resumed, the situation is that the cardiac output is poor and sufficient blood pressure and cardiac output cannot be maintained. At this time, the trainee is caused to perform a procedure for measuring the recovery of the cardiac output of the own heart. In an exemplary procedure, a trainee inputs cardiotonic medication for enhancing cardiac output as operation information. When this administration is successful, the cardiac output simulation value is improved. If this pattern does not work, or if the trainer did not properly administer the pattern, the trainer temporarily increased the pump blood flow in the extracorporeal circulation and then slowly decreased it as operation information. Enter. By this operation, it becomes possible to rest the self-heart temporarily and then measure the recovery of cardiac output slowly.
Example scenario 8
After releasing the aortic blockage, arrhythmias occur frequently, creating a situation where hemodynamics is not stable and the extracorporeal circulation cannot be terminated. At this time, the trainee is made to perform a procedure for stabilizing the hemodynamics. An exemplary procedure is to check the value of potassium in the electrolyte in plasma, and the trainer inputs information that makes the potassium value appropriate as operation information. Thereafter, an antiarrhythmic agent is administered to suppress the arrhythmia. If the arrhythmia still does not heal, entering the operation information that performs cardioversion for a lethal tachyarrhythmia results in a simulation value indicating that the arrhythmia is subsided.

  The system according to the present invention can also calculate the valve opening degree of each valve from an input event or an event included in a scenario. The following table shows the relationship between major events and valve opening. If the following table is prepared in advance and stored in the storage means, the valve opening degree of each valve is controlled individually by referring to the table according to the event input or included in the scenario. Thus, various trouble cases can be accurately reproduced, and more accurate training can be given to the trainer.

  FIG. 3 is a block diagram showing an example of the system configuration of the training apparatus for the extracorporeal circulation apparatus according to the present invention. As shown in the figure, an extracorporeal circulation apparatus training apparatus 200 according to the present invention includes an extracorporeal circulation apparatus operation console (input unit) 210, a simulated circulation unit 220 that simulates partial characteristics of hemodynamics, and real-time numerical values. It has a simulation device 230 and an information presentation display 250. The real-time numerical simulation device 230 utilizes a hemodynamic equivalent circuit simulation technique using a lumped constant circuit. The information presentation display 250 comprises a graphical user interface with a computer. The apparatus 200 integrates input and output by these components and functions, and provides a training environment for facilitating the acquisition of an extracorporeal ring device operation technique that has been difficult outside the clinical field. It can be widely used in terms of providing software that allows clinical engineers to practice images before driving the heart-lung machine.

  Practical training in the clinical field is performed under severe restrictions on time cost and human cost because there is a lack of absolute number of clinical engineers and not many cases using extracorporeal circulation devices. According to the present invention, it is possible to systematically learn the operation of the extracorporeal circulation apparatus as a pre-stage of practical training at the site, so that the effect of the practical training at the site can be maximized. In addition, accident cases that are extremely rare in actual clinical settings can be simulated through events and scenarios, and a great effect is expected as safety education for reducing medical accidents. The apparatus and program according to the present invention are also expected to be applied to clinical engineering technician qualification tests and cardiopulmonary device operation qualification tests.

  Further, if there is a personal computer equipped with computing means and a model of extracorporeal circulation, the device according to the present invention can be easily manufactured. The apparatus according to the present invention can also be used for training medical personnel other than clinical engineers, such as nurses, medical students, and doctors. In addition to blood pressure and circulating blood volume, the present invention can simulate various biological information such as heart rate, arrhythmia, cardiac output, body temperature, peripheral vascular resistance, or plasma electrolyte, and is widely used in the medical field. It can be used.
