Description

  The present invention relates to a technique of a simulation device for training a neonatal resuscitation method.

  When a doctor diagnoses a medical condition or disease name, as a part of the examination, a stethoscope (more precisely, a sound-collecting unit) is applied to the affected part of the patient to listen to body sounds (respiratory sounds, heart sounds, intestinal murmurs, etc.) It is done to judge.

  Here, the stethoscope is roughly divided into a sound collecting unit, a tube (also called a rubber tube) and an ear tube.

  Conventionally, auscultation training systems have been reported for trainees, such as medical students aiming to become doctors and nursing students aiming to become nurses, to learn auscultation techniques.

  For example, a device for auscultation education disclosed in Patent Document 1 includes a human body model formed by imitating an upper body of a human body, a simulated stethoscope for performing a simulated auscultation operation on the human body model, and a simulated stethoscope. The auscultation detection sensor for detecting the auscultation operation by, a mock stethoscope and the auscultation detection sensor are respectively connected, receive the detection signal sent from the auscultation detection sensor that has detected the auscultation operation, provided in the eustachian tube portion of the mock stethoscope And a control unit for performing processing for reproducing body sounds such as heart sounds and breath sounds at the auscultation position corresponding to the detection signal from the body sound reproduction unit.

  However, such an auscultation training system is basically aimed at training auscultation for adult patients.

  On the other hand, the neonatal mortality rate at birth in Japan (early neonatal mortality rate) is 0.7 per 1,000 births. This figure is far lower than that of other developed countries (3.7 in the United States), indicating that Japan's delivery environment has a high level of safety. Of course, the background is the high medical standard in Japan, but the characteristics of the actual delivery environment in Japan are summarized below.

    • Most deliveries are done at obstetric clinics or midwives, not at general hospitals.

    ・ Pediatricians (neonologists) are basically absent outside of general hospitals.

    • Although the proportion of high-risk mothers is high at general hospitals, not all deliveries are attended by pediatricians.

  According to statistics shown in Non-Patent Document 2, the number of medical workers related to delivery in Japan is, for example, 510 obstetricians, 36,000 midwives, and 1 neonatal physician in 2014. 238, anesthesiologists 8,625, and obstetrics and gynecology 10,575.

  This is where the challenges of the Japanese medical system lie. The number of births in Japan in the past few years has been less than one million, but the number of neonatal specialists who are neonatal specialists is only one-thousandth, and neonatal resuscitation specialists are present at many deliveries. Absent. In addition, many obstetricians and midwives are specialists in pregnancy to delivery, and their specialized skills for neonatal resuscitation are inadequate. In such a medical system, the fact that the neonatal mortality rate described above is reduced to 0.7 per 1,000 people can be said to be the result of unremitting efforts at medical sites.

  A specific activity is the Neonatal Cardio-pulmonary Resuscitation (NCPR) popularization project, which the Japan Society of Perinatal and Neonatal Medicine has been developing since 2008. In fact, according to statistics from the Ministry of Health, Labor and Welfare in 2015, about 100,000 newborn babies will be in a state of asphyxia with unstable respiratory circulation immediately after childbirth, requiring resuscitation. . As mentioned above, it is not enough for specialists to respond to the birth of all newborn babies, and all healthcare workers who are present at the birth have a reality to provide high-quality and safe care and cooperate with medical professionals. This means that the NCPR training for skill improvement, including skill improvement, must be continuously performed and the skills must be maintained. To this end, regular resuscitation seminars are held nationwide.

  The goal of the NCPR training is to "deduce the trainee's" awareness "through a resuscitation scenario exercise (using a simulator) and make an effective reflection", from three classes: classroom training, manual training, and scenario training. Classes are organized. In the classroom, students will learn about newborn resuscitation procedures and basic knowledge. In the technique training and scenario training, a simulator simulating a newborn baby is used, and learning of techniques such as artificial respiration and chest compressions and training in accordance with a scenario are performed.

  The simulator used in this scenario training has been put to practical use not only from a newborn baby's body structure, but also from a high-performance simulator that can reproduce various paitals to a simple newborn model that reproduces only the newborn's body structure. ing.

(High performance simulator)
In SimBaby (registered trademark) of Leardl, which is an example of a high-performance simulator, the simulator reproduces the state of the newborn baby such as heartbeat, breathing sound, and skin color, and the instructor can operate the state with a controller. In addition, various training scenarios are prepared in this system, and the trainee can simulate the scenarios. These functions are controlled by a computer. Needless to say, it is possible to present more realistic vital information such as heartbeats and cyanosis, and to reproduce it in many situations. However, such as the high cost of the simulator itself, the need for regular maintenance, and the instructor must be proficient in operating the simulator in order to smoothly proceed with the scenario exercises. Costs are high, and as a result, dissemination has not progressed sufficiently.

(Newborn resuscitation model)
Therefore, as for the simulator used in the actual NCPR training site, a simple and inexpensive newborn baby model that reproduces only a part of the structure of the newborn baby is mainly used. Because such a simple newborn model cannot reproduce the petal, the instructor transmits the petal to the trainee in a way that is far from actual, such as transmitting the heart rate by tapping the desk and transmitting the heart rate verbally. .

  For this reason, it is difficult for trainees to obtain appropriate feedback during the scenario exercise, and as a result there is concern that independent actions that are regarded as important in the course will be hindered and the learning effect in the course will be affected . Therefore, in order to realize training with a sense of urgency closer to reality, sufficient motivation and effort of both the instructor and the trainee are required. In addition, in this simplified model, in order to realize a high-quality training that simultaneously implements “reproduction of training scenario”, “guidance of students”, and “evaluation of training results”, it is necessary to rely on the training skills of the instructor. Absent.

  To cope with such a problem, Patent Document 2 discloses an auscultation training system. In this auscultation training system, the simulated sounding section of a simulated stethoscope for simulating a human body model formed by imitating a newborn human body can be attached to and detached from a rubber tube of a general stethoscope. It is. If the control computer determines from the sensor of the simulated sounding unit that the simulated sounding unit is in close contact with the epidermis of the human body model, it transmits heart sound data to the simulated sounding unit, and the simulated sounding unit transmits the corresponding heart sound. Reproduce.

  With such a configuration, in the auscultation training system for training of neonatal resuscitation, the introduction cost can be reduced, and at the same time, the training effect can be increased, but for healthcare workers related to delivery scattered in a large area. There were still challenges to improve the training effect based on "realism."

  As of September 2011, 118,805 training courses had been attended by the NCPR promotion project that started in 2008, which is well over the total number of laborers in Japan. On the other hand, early neonatal mortality during this period has not shown a clear decrease. On the other hand, the Japan Society of Perinatal Neonatal Medicine, which oversees the NCPR business, said, "Only some specialized facilities with high-performance simulators can receive real and high-quality neonatal resuscitation education. Is not in place, and how can delivery workers receive high-quality neonatal resuscitation training and adequate education to improve their skills? Has been viewed as a problem. On the other hand, in 2015, the Japan Resuscitation Council newly recommends “training using a simulator with reality”, and the guidelines of Non-Patent Document 2 propose “continuous tonning more than once a year”. It became a thing.

JRC Resuscitation Guidelines 2015 Online Version: http://www.NCPR.jp/guideline_update/pdf/jrc_guideline_2015.pdf

  As mentioned above, in the neonatal area, there is a system that provides rehabilitation simulation that satisfies both “cheap” and “real” at the same time as effective training over a wide area. It is difficult to conduct education widely and continuously, and the system to support instructor activities especially in the region is not sufficiently developed.

  In the current situation, the trainee uses a trainer to put a stethoscope on the resuscitation mannequin and visually judge the heart rate indicated by the instructor instead of hearing information. It is far from Ninging. Also, in many cases, in the NCPR workshops, it was difficult to train non-technical skills among the staff of the own facility because the trainees were a group of gatherings from local delivery facilities.

  In addition, the instructor observes the behavior of the trainee during the scenario exercise, checks if there is a problem with the procedure, and gives advice (debriefing) on the spot, There are many tasks that must be performed at the same time, such as transmitting information to them. Therefore, it is also difficult for a non-professional instructor to proceed with the course smoothly.

Therefore, as a solution to the problems facing the NCPR training, a solution that can use an existing simple neonatal model is desirable. It is an object of the present invention to provide an auscultation training system that can efficiently derive such “awareness” and can take the course “from anywhere” and “anytime”.

Hereinafter, an auscultation training system according to an embodiment of the present invention will be described with reference to the drawings.
[Embodiment]
FIG. 1 is a conceptual diagram illustrating an example of an auscultation training system 1000 according to the present embodiment.

  As shown in FIG. 1, the auscultation training system of the present embodiment is an IoT stethoscope (hereinafter, referred to as a trainee) used by a trainee to perform a simulated auscultation operation on a model doll imitating a newborn human body. , "Simulated auscultation module 200") and a controller 2000 for controlling auscultation training on the instructor side.

  Although not particularly limited, for example, the instructor-side controller 2000 may be a trainee-side simulated auscultation module 200 or a simulated medical device 3000 for training at a regional hospital or an overseas hospital from a regional base hospital or the like via a communication line. Data is sent and received between and.

  That is, the auscultation training system 1000 is attached to the stethoscope 100 used by the trainee, and trains a simulated auscultation module 200 having a sensor and a communication function part as described later and a simulated vital sign (biological information) of a newborn baby simulator. It includes a simulated medical device 3000 for presentation to a student, and a controller 2000 for an instructor to control a petal of a neonatal simulator. All functions other than the simulated auscultation module 200 can be realized as application software.

  The trainee can use his or her own stethoscope as it is. The simulated medical device 3000 and the controller 2000 can use hardware having a function of executing application software, such as a personal computer, a tablet terminal, or a smartphone.

  The presented biological information corresponds to the heart rate, oxygen saturation, crying, electrocardiography, etc., which are the criteria for selecting the resuscitation behavior of the medical physician indicated in the guidelines for the NCPR course. A simulated auscultation module 200 attached to a chest bead portion of a stethoscope 100 applied to a patient's body incorporates a contact sensor 18 (not shown) for measuring a reflected light amount of light emitted by itself. When the bottom surface of the simulated auscultation module 200 is placed on the body surface of the newborn baby model, the simulated auscultation module 200 measures a change in the amount of light with the contact sensor 18 and determines whether or not the simulated auscultation module 200 is in a contact state. The simulated auscultation module 200 transmits and receives information to and from the proximity wireless communication device 4000 (not shown) or the simulated medical device 3000 via a short-range wireless system, for example, a Bluetooth (registered trademark) wireless line. The proximity wireless communication device 4000 or the simulated medical device 3000 communicates with the controller 2000 via a communication line such as the Internet or a mobile phone line via a wireless LAN (Local Area Network) access point 4010 (not shown) or the like. To send and receive data.

  The controller 2000 generates an instruction to display and reproduce a heart sound at the heart rate set by the instructor, sends an instruction to display it to the simulated medical device 3000 via the communication line, and sends data of the heart sound to the simulated auscultation module 200. . The simulated auscultation module 200 connected to the proximity wireless communication device 4000 or the simulated medical device 3000 via Bluetooth (registered trademark) is provided with a small earphone as a speaker for reproducing heart sounds, and is in a contact state by the contact sensor 18. During the period in which is detected, the reproduced heart sound is output to the stethoscope 100 fixed to the simulated auscultation module 200.

  Therefore, only when the trainee applies the simulated auscultation module 200 to the body surface of the newborn model doll, the trainee hears the heart sound at the heart rate set by the instructor, which is almost the same as the normal stethoscope operation using the stethoscope 100. By the same operation, the user can simulate auscultation like "actual auscultation".

  Of course, in this method, the heart sound is reproduced no matter where the stethoscope is placed. However, for the trainee, the stethoscope 100 may be applied anywhere near the heart of the newborn as long as the heart rate is examined, and it is not necessary to put the stethoscope 100 in a different site during the training. There is no problem.

  Rather, the unnaturalness of giving a heartbeat sound with the sound of the instructor tapping the oral or desk, as in the conventional training, is more difficult than the unnaturalness of hearing the heartbeat sound in the other place of the newborn baby model. It hinders effectiveness and motivation. This leads to a behavior in which the trainee independently listens to the heart sound to make a judgment, and brings a completely different experience from the training using the conventional simple model.

  Further, except for the simulated auscultation module 200, the controller 2000 and the simulated medical device 3000 can be used by simply installing application software on all smartphones and tablet terminals, for example, so that the guide cost is extremely low.

  In the following, description will be made assuming that the simulated auscultation module 200 transmits and receives information to and from the proximity wireless communication device 4000 via a wireless line of a proximity wireless system, for example, a Bluetooth (registered trademark) system. However, as described above, the simulated auscultation module 200 is configured to transmit and receive information to and from the controller 2000 via the simulated medical device 3000 via a wireless line of a close proximity wireless system, for example, a Bluetooth (registered trademark) system. Is also good.

  FIG. 2 is a schematic diagram for explaining the configuration of the auscultation training system 1000.

  As shown in FIG. 2, the auscultation training system 1000 according to the present embodiment includes a stethoscope 100 used by a trainee to perform a simulated auscultation operation on a model doll 2 imitating a human body of a newborn baby. A simulated auscultation module 200, a controller 2000 for incorporating a body sound database as described later, and a controller 2000 for generating and transmitting an appropriate body sound to the simulated auscultation module 200, and according to a signal transmitted from the controller 2000. And a simulated medical device 3000 for simulating a pulse oximeter to display values of pulse rate and oxygen saturation.

  The simulated medical device 3000 is connected to the network 4100 via the access point 4010, and the controller 2000 is connected to the network 4100 via the access point 4200. The video camera 80 may be a web camera connected to the network 4100 via the access point 4010, or may be configured to connect to the network 4100 via the simulated medical device 3000. In the latter case, the simulated medical device 3000 and the video camera 80 may be connected by wire or wirelessly.

  In the following, the simulated medical device 3000 will be described as an example using a so-called tablet terminal.

Here, "pulse oximeter (pulse Oximeter)", the probe attach such a finger or an ear, is a medical device to monitor pulse rate and transcutaneous arterial oxygen saturation without invade (SpO ₂₎ . The “percutaneous arterial oxygen saturation” is an index indicating what percentage of oxygen is bound to hemoglobin. Thereby, the arterial blood oxygen partial pressure can be estimated. When the percutaneous arterial blood oxygen saturation is 90% or less, generally, clinical symptoms such as dyspnea, an increase or decrease in blood pressure, an increase in pulse, and opacity of consciousness appear.

  Note that a configuration is also possible in which the controller 2000 transmits simulated voice data equivalent to a cry of a newborn baby to the simulated medical device 3000 and reproduces the simulated medical device 3000 using a speaker.

  It is also possible to adopt a configuration in which the video camera 80 captures a moving image including both the trainee and the newborn baby model doll, and reproduces the image on the display device on the instructor side in real time. In this case, for example, the moving image data may be stored in the storage device of the controller 2000 while appropriately adding data serving as a mark such as a chapter mark according to an input from the instructor. By using the moving image data with the chapter mark, the instructor and the correct course can look back while sharing the reproduction of the moving image, and further enhance the training effect.

  The storage of the moving image data to which the chapter mark is added is not necessarily limited to the storage device in the controller 2000, and may be a storage device in the simulated medical device 3000 or a network. A storage device (not shown) in a server connected to the server 4100 may be used. In addition, not only chapter marks but also “comments” selected by the instructor from those displayed according to steps on the application side may be stored in such a storage device in association with moving images.

  FIG. 3 is an external view for explaining the configuration of the stethoscope 100.

  A general stethoscope is roughly divided into a sound-collecting unit, a tube (for example, when rubber is used as a material, also called a rubber tube; hereinafter, referred to as a “tube unit”) and an ear tube. Note that the sound pickup unit is also called a chest piece.

  As shown in FIG. 3, the stethoscope 100 is used by a doctor or a nurse at an actual medical site at the time of auscultation. In the configuration of the stethoscope 100, the chest piece 10, which is a sound collecting unit, is mounted on the simulated stethoscope module 200 as described later.

  Therefore, as shown in FIG. 3, the stethoscope 100 includes the sound pickup unit 10 mounted on the simulated auscultation module 200 having the auscultation surface that is in contact with the body surface of the model doll 2, and the sound pickup unit 10. It is attached to each end of the Y-shaped pipe portion 20 made of a soft material which is detachably connected and branched into two, and is attached to each end of the branched Y-shaped portion of the Y-shaped tube portion 20 and is inserted into the ear hole of the trainee. With possible ear canal sections 30a and 30b.

  FIG. 4 is an external view showing the external appearance of the simulated auscultation module 200 and the chestpiece 10.

  The upper surface of the simulated auscultation module 200 has a housing portion 210 having a shape capable of housing and fixing the chest piece 10, and the speaker 16 is provided on the upper surface side in the housing portion 210.

  Further, a contact sensor 18 described later is provided on the bottom surface of the simulated auscultation module 200.

  FIG. 5 is a functional block diagram for explaining the configurations of the controller 2000 and the simulated medical device 3000.

  In FIG. 5, a function executed by the controller 2000 or the simulated medical device 3000 is executed based on a program by a central processing unit (CPU) in the controller 2000 or the simulated medical device 3000 as described later. You.

  Referring to FIG. 5, wireless interface 3090 in simulated medical device 3000 exchanges data with controller 2000 via access point 4010 by wireless communication.

  Although the wireless communication system between the wireless interface 3090 and the access point 4010 is not particularly limited, for example, a wireless LAN can be used. Through the access point 4010, the network 4100, and the access point 4200, the wireless interface 3090 executes communication for data transfer between the controller 2000 and the simulated medical device 3000.

  The arithmetic device 3200 performs a process of displaying an image corresponding to a signal received via the wireless interface 3090 on the display device 3120 of the simulated medical device 3000 and performs a predetermined process in accordance with an input from the input device 3100. . The memory 3080 stores a program for a function to be executed by the simulated medical device 3000, or temporarily stores data corresponding to a signal received from the controller 2000 during training or a status flag of the simulated medical device 3000. used.

  If the memory 3080 is configured to store the moving image data from the camera 80 in the simulated medical device 3000, the data is stored.

  On the other hand, the wireless interface 2090 of the controller 2000 exchanges data not only with the simulated medical device 3000 but also with the simulated auscultation module 200 by wireless communication via the access point 4200, the network 4100, and the access point 4010. .

  From the simulated auscultation module 200, the detection result of the contact sensor 18 indicating whether or not the simulated auscultation module 200 is in close contact with the body surface of the model doll 2 is transmitted to the controller 2000 via the proximity wireless communication device 4000. It may be configured. In this case, when the closeness detection unit 2420 in the controller 2000 determines that the simulated auscultation module 200 is in close contact with the body surface of the model doll 2 based on the received signal from the contact sensor 18, the closeness detection unit 2420 associates the simulated auscultation module 200 with the time information, and The state is stored in the test history information DB 2450d.

  On the other hand, the currently set body sound data is transmitted from the controller 2000 to the simulated auscultation module 200 via the access point 4010 and the close proximity wireless transfer device 4000.

  The currently set values of the pulse rate and the oxygen saturation are transmitted from the controller 2000 to the simulated medical device 3000, and the simulated medical device 3000 displays the received data.

  The body sound transmission unit 2430 sends the currently set body sound data (for example, heart sound data corresponding to the set heart rate) to the simulated auscultation module 200 via the wireless interface 2090 at a predetermined timing. Send. Here, one of the predetermined timings may be, for example, when communication is first established after the system is started up, or from the simulated auscultation module 200, the simulated auscultation module 200 is placed on the body surface of the model doll 2. The detection result of the close contact may be transmitted to the controller 2000 for the first time.

  Then, the body sound transmission unit 2430 reads the body sound data currently set by the body state information 2450b from the body sound database (hereinafter, body sound DB) 2450a stored in the nonvolatile storage device 2080, and performs the simulated auscultation. The message is transmitted to the module 200.

  It is assumed that the body sound DB 2450a stores, for example, heart sound data corresponding to symptoms, other body sound data and crying data that are supposed to be auscultated in resuscitation of a newborn baby. The heart sound data may be stored in advance for each heart rate, or sound data of a predetermined reference heart rate may be stored, and the body sound transmitting unit 2430 may specify the reference heart rate sound data. The data may be converted into data of the heart rate.

  The body sound DB 2450a is stored in a storage device in a server connected to the network 4100 described above, and is transmitted from the server to the simulated auscultation module 200 in accordance with an instruction from the body sound transmission unit 2430. It may be a configuration.

  The test algorithm information 2450c stored in the non-volatile storage device 2080 stores scenario information corresponding to a neonatal resuscitation algorithm as described later, and the biological condition information 2450b stores a newborn baby model to be currently trained. , The percutaneous arterial blood oxygen saturation value, and the like are stored. The biological state information 2450b stores a current value in addition to the initial value, and the current value can be changed by an input operation performed by an instructor from the input device 2100.

  The test information management unit 2460 is used to display information for displaying an image on the display device 2120 of the controller 2000 and display an image on the simulated medical device 3000 based on the information stored as the test algorithm information 2450c and the biological condition information 2450b.

In this case, the configuration is such that the respiratory rate can be changed according to the input from the input device 2100 of the instructor. The set respiration rate is stored in the biological condition information 2450b.

  Based on the time information from the timer 2470, the test history recording unit 2470 associates the test history information about the trainee during training with a test history database (hereinafter, test history DB) 2450d in association with time information from the start of training. And store it for each trainee.

  FIG. 6 is a functional block diagram for explaining the configuration of the simulated auscultation module 200.

  The simulated auscultation module 200 includes a housing portion 210 having a shape for housing and fixing the chest piece 10.

  The contact sensor 18 is provided in the vicinity of the center of the surface (bottom surface) of the simulated auscultation module 200 on the side opposite to the housing section 210. Since the simulated auscultation module 200 is made of a material that does not transmit light, when the surface comes into close contact with the body surface of the model doll 2, the light emitted from the light emitting element of the contact sensor 18 is received by the contact sensor 18. The amount of light incident on the sensor decreases below a predetermined value. Therefore, the degree of close contact of the simulated auscultation module 200 can be determined based on the value detected by the contact sensor 18.

  Note that the sensor for detecting the degree of close contact of the simulated auscultation module 200 is not limited to such a contact sensor, and another pressure sensor or the like may be used.

  Inside the simulated auscultation module 200, a wireless communication unit 12 for performing wireless communication with the close proximity wireless communication device 4000 and body sound data received by the wireless communication unit 12 are stored, and the contact state is detected by the contact sensor 18. For a period during which the sound is detected, a sound reproducing unit 14 for converting the sound to a sound signal for reproduction, a small speaker 16 for outputting the output of the sound reproducing unit 14 as sound, and a signal from the contact sensor 18 are output. A sense data transmitting unit 21 for converting the data into a data format to be transmitted to the controller 2000 via the wireless communication unit 12, and a battery unit 20 for supplying power to each unit. The small speaker 16 outputs a reproduced sound to the sound pickup side of the chest piece 10 housed in the housing section 210.

(Hardware configuration)

ROM 2060, a RAM 2070 for temporarily storing instructions of application programs and providing a temporary storage space, and a non-volatile storage device (for example, SSD: Solid State) for storing application programs, system programs, and data. Drive 2080) and a wireless communication interface 2090 for communicating with external devices via a network or the like.

  Each function of FIG. 5 described above is realized by the arithmetic processing executed by the CPU 2040 based on the program.

  A program that causes the controller 2000 to execute the functions such as the information processing of the above-described embodiment is stored in the CD-ROM 2200 or the memory medium 2210 and inserted into the disk drive 2030 or the memory drive 2020. 2080. Alternatively, the program may be transmitted to computer main body 2010 via a network (not shown) and stored in nonvolatile storage device 2080. The program is loaded into the RAM 2070 during execution.

  The controller 2000 further includes a keyboard 2100a and a mouse 2100b as an input device 2100, and a display 2120 as an output device.

  An operating system (OS) that causes the computer main body 2010 to execute the functions of the information processing device or the like does not necessarily need to be included in the program for realizing the functions described above. The program need only include an instruction part that calls an appropriate function (module) in a controlled manner and obtains a desired result. It is well known how the controller 2000 operates, and a detailed description is omitted.

  Further, CPU 2040 may have a single-core configuration or a so-called multi-core configuration. The computer that executes the program may be a single computer or a plurality of computers. That is, centralized processing or distributed processing may be performed.

  Note that the controller 2000 may also be a so-called tablet terminal or smartphone. In that case, the input device 2100 can be a touch-sensitive display incorporated in the display 2120. Also, the disk drive is omitted.

Furthermore, the hardware configuration of the simulated medical device 3000 is basically the same as that of the controller 2000, and as described above, the simulated medical device 3000 may be a tablet terminal.
[Newborn resuscitation algorithm]
FIG. 8 is an algorithm diagram for explaining the “newborn resuscitation algorithm” disclosed in Non-Patent Document 2.

  This “newborn resuscitation algorithm” is described in detail in Non-Patent Document 2, and the outline thereof will be described below.

  First, the target of this "neonatal resuscitation algorithm" is resuscitation of infants (less than one month old) who are in the delivery room, neonatal room and neonatal intensive care unit (NICU). .

Cardiopulmonary resuscitation may be applied to infants (newborns) with cardiac arrest less than 28 days during emergency resuscitation in pre-hospital rescue, pediatric wards and pediatric intensive care units, wards and outpatients.

(Flow of resuscitation)
The determination as to whether resuscitation is necessary for a newborn immediately after birth is made of three items: i) premature birth, ii) weak breathing / weak crying, and iii) decreased muscle tone (S100).

  For those who do not recognize all of them, routine care is performed near the mother (S110).

  Routine care involves warming, opening the airway, drying the skin, and then evaluating the child.

(Step of resuscitation)
On the other hand, if at least one of the three items is applicable in S100, the process proceeds to a resuscitation step.

That is, when it is determined in S100 that resuscitation is necessary, the infants who need resuscitation sequentially evaluate whether or not the following treatment is necessary.
(1) Initial treatment for resuscitation (wiping the amniotic fluid from the skin, keeping it warm, taking a position to secure the airway, sucking the airway if necessary, and stimulating the skin to induce respiration) (S120)
(2) Artificial respiration and respiratory assistance (S132)
(3) Chest compression (S136)
(4) Drug administration or fluid replacement (S140)
Whether or not to proceed to the next step is determined by simultaneously evaluating two vital signs (heart rate and respiration). Proceed to the next step after completing the previous step. At each step, approximately 30 seconds are allotted to perform the procedure and the effect of the procedure is reevaluated to determine whether to proceed.

1) Initial treatment of resuscitation and its evaluation (S120 to S130)
In the initial resuscitation procedure (S120), the amniotic fluid on the skin is wiped, kept warm, the airway is positioned, the airway is aspirated if necessary, and the skin is stimulated to induce respiration.

  Approximately 330 seconds after birth after the end of the initial resuscitation procedure, the effect is evaluated by heart rate and respiration (S130). Confirmation of heart rate is more reliable by auscultation than by palpable umbilical beats. Also consider using a pulse oximeter to assess heart rate and oxygenation in children who are expected to need resuscitation.

  If there is spontaneous breathing and the heart rate is 100 / min or more, the presence / absence of forced breathing and central cyanosis is evaluated (S150). In particular, consider attaching an ECG (electrocardiogram) monitor to children receiving artificial respiration, as needed, for the purpose of measuring the heart rate faster and more accurately.

  When forced breathing and central cyanosis are recognized, a pulse oximeter is worn, and continuous positive airway pressure (CPAP) using air or free-flow oxygen administration is started (S152).

SpO ₂ value corresponding to the birth time, 60% at 1 minute after birth, 70% in 3 minutes after birth, 80% at 5 minutes after birth, but the approximate guideline 90% in 10 minutes age, the SpO ₂ value You don't have to wait for the result.

  Further, after approximately 30 seconds, the heart rate and respiration are evaluated (S154). If no improvement in forced breathing and central cyanosis is recognized even though the heart rate is 100 / min or more, artificial respiration is started (S156). .

  The number of times of artificial respiration is 40 to 60 times / minute. If only one of them persists ("none" in S154), an appropriate response is selected while searching for causes (congenital heart disease, neonatal transient polypnea, respiratory distress syndrome, etc.) (S158, S160). ).

  On the other hand, when there is no spontaneous respiration or the heart rate is less than 100 / min in the evaluation after the initial treatment (S130), artificial respiration is started and the pulse oximeter is worn (S132). Pant breathing is treated in the same way as apnea. The number of times of artificial respiration is 40 to 60 times / minute.

  Approximately 30 seconds after the start of effective artificial respiration, the heart rate and respiration are evaluated (S134). If the heart rate is less than 60 to 100 / min, it is confirmed whether ventilation is appropriate and the implementation of tracheal intubation is examined.

  If the heart rate is less than 60 / min even if effective artificial respiration is performed for 30 seconds or more (S134), chest compressions and artificial respiration are started in conjunction (S136). However, when performing artificial respiration, if ventilation is not properly performed, do not proceed to chest compressions and concentrate on securing and implementing ventilation. The ratio between chest compressions and rescue breathing is 3: 1, with a cycle of 2 seconds as a guide.

(Drug administration or replacement fluid)
If the heart rate is less than 60 / min (S138) despite effective rescue breathing and chest compressions, consider administration of adrenaline (S140). However, the evidence for adrenaline is poor, and it is not a procedure to interrupt ventilation and chest compressions. Consider administration with priority given to artificial respiration and chest compressions. Adrenaline is the first choice for intravenous administration of 0.01-0.03 mg / kg.

  If blood loss is suspected in a baby, 10 ml / kg of a circulating blood expander (such as saline) is administered intravenously over 5 to 10 minutes. Chest compression and artificial respiration continue in conjunction with drug administration.

  As will be described below, the auscultation training system according to the present embodiment provides training so that the trainee can appropriately execute the procedure of the “newborn resuscitation algorithm”.

  FIGS. 9 and 10 are flowcharts for explaining the operations of the controller 2000, the simulated medical device 3000, and the simulated auscultation module 200 during training.

  Referring to FIG. 9, when the processing is started, first, the instructor inputs training date and instructor name from controller 2000 (S 200), and the trainee inputs trainee name from simulated medical device 3000. Etc., and exchange information with each other (S300).

  Note that the input of the instructor name, the input of the trainee name, and the like may be the input of an ID as long as the information can identify these individuals. The input training date and time, instructor name input, and trainee name information are stored in the test history DB 2450d.

  Subsequently, in response to the start input by the instructor, the controller 2000 initializes the screen display and variables, and starts time counting by the timer 2480 (S202).

  Next, the test information management unit 2460 displays the neonatal resuscitation algorithm diagram shown in FIG. 8 on the display device 2120, and also displays the current step corresponding to which step of the neonatal resuscitation algorithm diagram (see FIG. 8). S204). Further, information of such an algorithm diagram and a diagram showing the state of the current step is transmitted to the simulated medical device 3000, and the simulated medical device 3000 displays the corresponding information (S302).

  The test information management unit 2460 reads the current heart rate and the value of the percutaneous arterial oxygen saturation by the pulse oximeter from the biological condition information 2450b, and displays the value corresponding to the display device 2120 (S206).

  The test information management unit 2460 also causes the display device 3120 to display the current heart rate and the percutaneous arterial oxygen saturation value.

  In the initial state, the pulse oximeter is not mounted. At this point, not a specific value is displayed, but a display indicating that the pulse oximeter is not mounted is displayed.

  Further, in the controller 2000, the body sound transmitting unit 2430 reads the current heart rate from the biological state information 2450b, generates corresponding heart sound data, and transmits the data to the simulated auscultation module 200 (S206). In the simulated auscultation module 200, the heart sound data is received, and the sound reproducing unit 14 stores the sound data (S402).

  In the simulated auscultation module 200, when the heart sound data is received, the sound reproducing unit 14 makes a contact determination based on a signal from the contact sensor 18 (S404), and when it is determined that a contact state is present (Y in S408), the sound is stored. The reproduced heart sound data is reproduced (S410), and the process returns to S404 for performing contact determination. On the other hand, when determining that the state is not the contact state (N in S408), the sound reproducing unit 14 enters a standby state without reproducing the sound until the state is determined to be the contact state. However, even in the standby state, if it is determined that the heart sound data has been received (Y in S406), the process returns to step S402.

  Subsequently, the test information management unit 2460 displays the check items in the current step on the display device 2120 (S210).

  FIG. 11 is a diagram illustrating an example of a display screen on the display device 2120 in such a state.

  On the left side of FIG. 11, the “newborn resuscitation algorithm” shown in FIG. 8 is displayed, and the current step is displayed by a bold frame or color change. On the right side of FIG. 11, check items are displayed, and the current heart rate and the value of percutaneous arterial oxygen saturation, the elapsed time since the current step, the presence / absence of respiratory sound reproduction, and the like are displayed. Is done.

  The instructor can change the values of the heart rate and the percutaneous arterial blood oxygen saturation by moving the display bar.

  As for the check items, the result of checking the displayed contents by the instructor is input. Also, an input as to whether to proceed to the next step in the flow of FIG. 8 is displayed. Note that it may be possible to input whether to return to the previous step in the flow of FIG. 8 and to return the processing from the current step to the previous step.

  Returning to FIG. 9, test information management section 2460 determines whether or not a change in the values of the heart rate and the percutaneous arterial oxygen saturation has been input by the instructor, and if the change has been input (Y in S212). Then, the information of the biological condition information 2450b is updated and recorded, and the corresponding value is displayed on the display device 2120 (S214). Further, based on the signal from the test information management unit 2460, the display unit 3120 of the simulated medical device 3000 displays the updated values of the heart rate and the percutaneous arterial blood oxygen saturation (S316). The body sound sending unit 2430 reads the updated heart rate from the body state information 2450b, generates corresponding heart sound data, and sends it to the simulated auscultation module 200 (S214).

  If the simulated auscultation module 200 determines in S406 that heart sound data has been received via the network 4100, it receives and stores the heart sound data (S402).

  Subsequently, the test information management unit 2460 determines whether or not an input has been made for the check item by the instructor (S218). If there is an input, the display content is changed to a display indicating that the display device 2120 has been checked. (S220), the test history recording unit 2470 stores the current step, the current time, and the content of the check item in the test history DB 2450d (S222).

  Next, referring to FIG. 10, test information management section 2460 determines whether or not the lecturer has input an instruction to interrupt (Y in S224). The time is recorded in the test history DB 2450d (S226). Further, the test information management unit 2460 waits until an interruption release is input (N in S228). If the interruption is released (Y in S228), the test history recording unit 2470 sets the release time to the test history DB 2450d. (S230).

  Subsequently, the test information management unit 2460 determines whether or not the shift to the next step has been input by the instructor (S232). If the shift has been input, the step in the flow of FIG. The history recording unit 2470 records the time at which the step ends, in the test history DB 2450d (S234), and returns the process to step S204.

  On the other hand, if termination is instructed by the instructor (Y in S240), test information management unit 2460 terminates the process. If termination is not instructed (N in S240), the process returns to step S206. .

  As described above, according to the auscultation training system of the present embodiment, by mounting the simulated auscultation module 200 on a normal stethoscope, a flow of processing necessary for auscultation operation and resuscitation in a procedure for resuscitation of a newborn baby is performed. Is performed on the model doll 2, so that the trainee can experience the tension under the same tension as the actual treatment.

  In addition, since the instructor can appropriately change the condition of the newborn baby during training, the training can be performed in a state closer to the actual treatment.

  In addition, since the history data during the training is stored one by one, the instructor and the trainee share the action during the training with the moving image or the still image extracted from the moving image after the training is completed. It is easy to look back while watching, and it is possible to enhance the training effect.

  In addition, since the components constituting the training system are composed of simple and low-cost component members, if a specific trainee is proficient to some extent, it is easy to perform auscultation training among the trainees.

  Hereinafter, the effect of the auscultation training system of the present embodiment will be supplementarily described.

  FIG. 12 is a conceptual diagram showing a comparison between the conventionally used simulator as described above and the auscultation training system of the present embodiment.

  In FIG. 12, it is shown by the axes of introductivity and training effect. There is a trade-off between the training effect and the introduction, and the auscultation training system of the present embodiment is easy to introduce and has a high training effect.

  Here, in order to enhance the training effect, it is considered that the simulator can be achieved simply by bringing the simulator closer to reality.

  In the neonatal resuscitation training, the following vital reproduction method can be considered in order to make a response close to that of a real newborn by a simulator that simply simulates the shape of the newborn.

a) Heart rate can be measured by auscultation b) Arterial blood oxygen saturation (SpO2) can be displayed and confirmed by a pulse oximeter c) The condition of the newborn varies depending on the student's treatment Therefore, the auscultation training system of the present embodiment In this example, the contents that need to be reproduced can be simulated.

  Further, in the auscultation training system of the present embodiment, as described above, in order to enhance the training effect, it is necessary for the trainee to be able to perform auscultation in the same way as at a clinical site, even in training away from the instructor. There is. In addition, the trainee performs treatment according to the heart rate, and the heart rate changes according to the treatment. Therefore, the instructor changes the heart rate while watching the treatment of the trainee.

  In order to solve these problems, the following functions are achieved in the auscultation training system of the present embodiment.

Function 1) Simulator that allows trainees to independently perform auscultation Function 2) Controller that allows instructor to control heart rate freely according to the student's treatment Function 3) Have a sense of presence even when the instructor and the student are away from each other Communication environment where training is possible (simulator for trainees)
As described above, the trainee's simulator is composed of a simulated auscultation module incorporating a neonatal resuscitation model and sensors. In actual diagnosis, correct auscultation cannot be performed unless the bottom surface of the simulated auscultation module attached to the chest piece is brought into close contact with the newborn's chest.

When the contact sensor's detection value falls below a certain value, it is determined that they are in close contact, and a simulator that allows trainees to perform auscultation by sending a heartbeat sound set by the instructor from the speaker built into the simulated auscultation module Is done.
(Controller on the instructor side)
On the other hand, on the controller screen of the controller 2000, a flowchart expressing the algorithm of the neonatal resuscitation method created by the Japan Resuscitation Council, a checklist for each item of the flowchart provided by the neonatal resuscitation extension business, and a selection bar for the heart rate , Arterial blood oxygen saturation selection bar and elapsed time are displayed.

  In the scenario-based training, the scenario runs according to the flowchart, so that the instructor can check the progress of the training in the flowchart. In addition, the checklist is switched and displayed according to each treatment item so that the behavior of the trainee with respect to the ongoing treatment can be immediately evaluated. Also, according to the scenario, the instructor prepares an input cover to operate the heart rate and arterial blood oxygen saturation heard from the chest piece so that the heart rate and arterial blood oxygen saturation can be changed at any time while watching the student's treatment. I have.

  Further, in the algorithm of the neonatal resuscitation method, a standard time for performing the treatment is set, and the elapsed time of the training is also displayed so that the instructor can confirm whether or not the trainee's treatment is being performed according to the standard time.

  In addition, trainees are encouraged to review their simulation results after training.

  Therefore, in order to provide materials for the trainee to look back on the simulation, it is possible for the instructor to present the result of the checklist in which the trainee checked the behavior of the trainee during the training after the training. For example, it is possible to indicate whether all the checklists for each item are checked by × or to indicate the check state of all checklists in a list.

  Furthermore, in the training using the scenario in the training session, the instructor proceeds while asking the trainees. Therefore, the training is temporarily stopped and restarted, and a function for displaying the elapsed time according to the training is provided.

  In addition, as an effective feedback to the trainee, the flow chart presented at the time of reflection may be configured to display the flow of the scenario planned by the instructor and the result of the action actually performed by the trainee as a flow. Good.

  Furthermore, since what kind of breathing can be determined from the voice of the newborn, it may be configured to reproduce the voice of the newborn according to the scenario.
