Description

  The present invention relates to a resuscitation training human body model used for learning the cardiopulmonary resuscitation method, and a resuscitation training system including the resuscitation training human body model.

  Conventionally, in order to perform cardiopulmonary resuscitation quickly and accurately, training of cardiopulmonary resuscitation using a human model for resuscitation training has been performed. This human body model for resuscitation training is configured such that a learner who learns cardiopulmonary resuscitation can train chest compression heart massage (hereinafter simply referred to as “chest compression”) and the like.

  For example, in Patent Document 1, a human body model housing having a simulated chest simulating a human chest, a coil spring incorporated in the body model housing and extending and contracting each time the simulated chest is pressed, and a human body model housing A resuscitation training human body model is disclosed that includes a load cell that is incorporated therein to detect the amount of contraction of the coil spring and a control board that calculates the compression depth of the simulated chest from the output signal of the load cell. In Patent Document 1, a learner trains chest compression using the human body model for resuscitation training.

JP-A-8-190340

  However, in Patent Document 1, the coil spring expands and contracts every time the learner compresses the simulated chest during chest compression training. Therefore, every time the learner presses the simulated chest, the coil spring generates a stretching sound. Further, when the learner strongly presses the simulated chest, the spring wires constituting the coil spring come into contact with each other, and the coil spring generates a mechanical contact sound.

  Therefore, the resuscitation training human body model of Patent Document 1 has a problem of generating noise such as stretching sound and contact sound.

  Further, the chest compression by the expansion and contraction of the coil spring in the human body model for resuscitation training of Patent Document 1 has a problem that a real feeling close to the human body cannot be obtained unlike the actual chest compression on the human body.

  An object of the present invention is to provide a resuscitation training human body model and a resuscitation training system that allow a learner to experience chest compression that achieves reduction of noise generated during chest compression training and realism close to the human body. It is in.

  The human body model for resuscitation training of the present invention has the following configuration in order to solve the above problems.

(1) a human body model housing having a simulated chest that simulates the chest of a human body;
A compression table disposed in the human body model housing and provided on the back side of the simulated chest of the human body model housing;
An air suspension disposed in the human body model casing and extending and contracting each time the compression table is compressed through the simulated chest.

In this configuration, a learner who learns chest compression performs chest compression by placing a hand on the simulated chest of the human body model case and repeating the compression.
When the learner compresses the simulated chest, the simulated chest is pressed against the air suspension by the compression force, and the air suspension is contracted. On the other hand, when the learner stops the compression, the air suspension stretches and pushes up the simulated chest.

Here, in this configuration, an air suspension using the elasticity of air is used instead of the coil spring. Therefore, every time the learner presses the simulated chest, no stretching sound is generated. Further, when the learner strongly presses the simulated chest, no mechanical contact sound is generated.
Further, the compression of the sternum by the expansion and contraction of the air suspension provides a realistic feeling close to that of the human body as compared with the compression of the sternum by the expansion and contraction of the coil spring.

  Therefore, according to this configuration, the learner can experience chest compression that realizes reduction of noise generated during chest compression training and realism close to the human body.

(2) The air suspension may incorporate a leaf spring having a rectangular cross section.

  In this configuration, the elasticity of the leaf spring and the elasticity of the air of the air suspension are used together. And if it is a leaf | plate spring in which a cross section is a rectangular shape, compared with a spring with a circular cross section, it is hard to contact spring wires. Therefore, according to this structure, the noise (namely, contact sound) which generate | occur | produces at the time of chest compression training can be reduced, utilizing the elastic force of a leaf | plate spring.

(3) The human body model housing may have a vent hole at a location facing the simulated chest.

  In this configuration, every time the learner presses the simulated chest, the air inside the human body model case flows in and out through the vent hole. Therefore, in this configuration, every time the learner presses the simulated chest, the air pressure inside the human body model housing does not increase or decrease.

Therefore, in this configuration, every time the learner presses the simulated chest, high-pressure air flows in and out through the gap between the human body model housing (for example, the joint between the simulated chest and the simulated back). There is nothing. That is, there is no inflow sound or outflow sound of high-pressure air.
Therefore, according to this structure, the noise which generate | occur | produces at the time of chest compression training can be reduced more.

(4) The control unit includes a detection unit that detects a contraction amount of the air suspension, and a compression depth detection unit that detects a compression depth of the simulated chest based on a detection signal output from the detection unit.

  In this configuration, the compression depth of the simulated chest is detected from the expansion and contraction of the air suspension. Therefore, by feeding back the detected depth of compression of the simulated chest to the learner, it is possible to make the learner know the correct depth and strength of chest compression.

(5) The control unit counts the number of compressions of the simulated chest based on the detection signal output from the detection unit, and detects the compression tempo of the simulated chest, which is the number of compressions of the simulated chest per unit time. A compression tempo detection unit.

  In this configuration, the compression tempo of the simulated chest is detected from the expansion and contraction of the air suspension. Therefore, by feeding back the detected compression tempo of the simulated chest to the learner, it is possible to make the learner know the correct tempo compression tempo.

(6) The control unit includes a return position detection unit that detects a return position when releasing the compression of the simulated chest based on a detection signal output from the detection unit.

  In this configuration, the return position at the time of releasing the compression of the simulated chest is detected from the expansion and contraction of the air suspension. Therefore, the learner can be made to know the correct return position at the time of releasing the chest compression by feeding back to the learner the return position at the time of releasing the detected compression of the simulated chest.

(7) Compression depth of the simulated chest detected by the compression depth detection unit, compression tempo of the simulated chest detected by the compression tempo detection unit, and compression release of the simulated chest detected by the return position detection unit An informing unit for informing at least one of the return position at the time and the ideal compression tempo of the simulated chest is provided.

  In this configuration, the learner can know at least one of the compression tempo, the compression depth, the return position when releasing the compression, and the ideal compression tempo performed during the chest compression training from the notification unit. Therefore, according to the human body model for resuscitation training having this configuration, the learner's skill in chest compression can be dramatically improved.

(8) The control unit includes a first mode that permits the notification by the notification unit, and a second mode that prohibits the notification by the notification unit,
A selection unit is provided that receives selection of either the first mode or the second mode.

  In this configuration, in the first mode, the learner knows at least one of the compression tempo, the compression depth, the return position when releasing the compression, and the ideal compression tempo performed in the chest compression training from the notification unit. Can do.

  However, the second mode is a mode closer to actual chest compression than the first mode. In the second mode, the learner cannot know from the notification unit at least one of the compression tempo, the compression depth, the return position when releasing the compression, and the ideal compression tempo performed during the chest compression training.

  In the second mode, the learner or medical worker, after completion of the chest compression training, sets at least one of the compression tempo, the compression depth, and the return position when releasing the compression performed in the chest compression training to a predetermined computer described later. Check with

  Therefore, according to this structure, the effect of a learner's chest compression training can be confirmed. Moreover, according to this structure, the chest compression skill of a medical worker can be confirmed.

(9) At the compression depth of the simulated chest detected by the compression depth detection unit, the compression tempo of the simulated chest detected by the compression tempo detection unit, and the compression release detected by the return position detection unit A transmission unit is provided that transmits at least one of the return positions as training data.

  In this configuration, the transmission unit transmits a chest compression training result to a predetermined computer.

  Moreover, the resuscitation training system of this invention is equipped with the following structures in order to solve the said subject.

(10) The human body model for resuscitation training described in (9) above,
And an information processing apparatus including a receiving unit that receives the training data transmitted from the transmitting unit and a display unit that displays the training data received by the receiving unit.

  In this configuration, the information processing apparatus is, for example, a personal computer or a PDA. In this configuration, by using the human body model for resuscitation training described in (9) above, the learner can obtain at least one of the compression tempo, the compression depth, and the return position performed in the chest compression training after the training is completed. You can know in detail on the display.

  Therefore, according to the resuscitation training system of this structure, a learner's skill of chest compression can be improved dramatically.

  According to the present invention, there is provided a resuscitation training human body model and a resuscitation training system that allow a learner to experience chest compression that achieves a reduction in noise generated during chest compression training and realism close to the human body. Can do.

Hereinafter, the resuscitation training system according to the embodiment of the present invention will be described.
FIG. 1 is a system configuration diagram of a resuscitation training system 101 according to an embodiment of the present invention. The resuscitation training system 101 includes a resuscitation training human body model T1 and a personal computer 90 corresponding to the information processing apparatus of the present invention.

  The resuscitation training human body model T1 includes a simulated chest that simulates the chest of the human body, a simulated abdomen that simulates the abdomen of the human body, and a simulated back that simulates the back of the human body. The resuscitation training human body model T1 is configured such that a learner who learns chest compression heart massage (hereinafter simply referred to as “chest compression”) can train chest compressions. The resuscitation training human body model T1 and the personal computer 90 are connected by a USB cable C, as will be described in detail later.

  In the resuscitation training system 101 described above, the learner performs chest compression by repeatedly placing pressure on the simulated chest of the resuscitation training human body model T1. Upon completion of chest compression training, the resuscitation training human body model T1 transmits training data indicating a training result trained by the learner to the personal computer 90 via the USB cable C. When receiving the training data, the personal computer 90 displays the training result based on the training data on the display 91 (see FIG. 10 described later).

Here, the structure of the human body model T1 for resuscitation training is demonstrated below.
2 and 3 are external perspective views of the resuscitation training human body model T1 provided in the resuscitation training system 101 shown in FIG. The resuscitation training human body model T1 includes a human body model housing 1, a display unit 30, a speaker 31, an operation unit 32, a simulation housing 37, and a handle 38. Details of the display unit 30, the speaker 31, and the operation unit 32 will be described later.

  The human body model housing 1 includes a simulated chest part 3A simulating a human chest, a simulated abdomen part 3B simulating a human abdomen, and a simulated back part 2 simulating a human back part. The thickness of the simulated chest 3A is, for example, 10 mm. The inside of the human body model housing 1 is surrounded by a skin 4 made of a flexible synthetic resin, a simulated back portion 2, and a simulation housing 37.

  The epidermis 4 constitutes a simulated chest 3A and a simulated abdomen 3B, and is attached to the simulated back 2 with a pin (not shown). The skin 4 is made of a polyether-based flexible polyurethane foam. Polyether-based flexible polyurethane foams are excellent in durability, such as small stickiness, good restorability, and hardly hydrolyze.

  As shown in FIG. 2, the handle 38 is rotatably attached to the simulation casing 37. When the learner carries the resuscitation training human body model T1, the learner rotates the handle 38 as shown in FIG. 3 and carries the resuscitation training human body model T1 with the handle 38.

  4 is a side view of the inside of the resuscitation training human body model T1 shown in FIG. FIG. 5 is a cross-sectional perspective view of the resuscitation training human body model T1 shown in FIG. The resuscitation training human body model T1 includes the control board 25 inside the simulation housing 37, and the air suspension 7, the plate-like compression table 19, and the rotation angle sensor 40 inside the human body model housing 1. In the human body model housing 1, a plurality of vent holes 6 are formed at the location of the simulated back 2 facing the simulated chest 3A.

  Although details will be described later, the control board 25 is a board that controls the operation of each part of the resuscitation training human body model T1.

  The air suspension 7 includes a cylinder 12, a plate spring 17, a spring receiver 14, a support column 15, a cylinder 22, and a base plate 11.

  A base plate 11 is attached to the simulated back 2 as shown in FIGS. To the base plate 11, the lower end of the support column 15 and the bottom surface of the cylinder 22 are fixed. A spring receiver 14 is fixed to the upper end of the column 15. A support column 15 is accommodated in the cylinder 22. Inside the cylinder 22, the cylinder 12 is fitted along the support column 15 so as to be slidable in the vertical directions F1 and F2.

  The upper surface of the cylinder 12 is joined to the rear surface of the compression table 19. A leaf spring 17 having a rectangular cross section is housed in the cylinder 12. In addition, a spring receiver 14 and a part of the support column 15 are fitted inside the cylinder 12. Therefore, air A is enclosed in a space surrounded by the back surface of the compression table 19, the inner surface of the cylinder 12, and the upper surface of the spring receiver 14.

  The leaf spring 17 is interposed between the spring receiver 14 and the compression table 19 in a contracted state so that the length Z of the leaf spring 17 is shorter than the natural length of the leaf spring 17. The upper end of the leaf spring 17 is joined to the back surface of the compression table 19, and the lower end of the leaf spring 17 is joined to the spring receiver 14.

  The compression table 19 is supported by the cylinder 12 and the leaf spring 17 so as to be slidable in the vertical directions F1 and F2. Further, the upper surface of the compression table 19 is joined to the back surface of the simulated chest 3A. Therefore, when the compression table 19 is displaced in the downward direction F1, the spring receiver 14 is not displaced, but the cylinder 12 is displaced in the downward direction F1, the leaf spring 17 is also contracted in the downward direction F1, and the air A is also compressed.

  That is, in the resuscitation training human body model T1 of this embodiment, the elasticity of the leaf spring 17 and the elasticity of the air A of the air suspension 7 are used in combination.

  In this embodiment, the air suspension 7 incorporates the leaf spring 17, but the present invention is not limited to this. In implementation, an air suspension having a structure without a spring may be used.

  The rotation angle sensor 40 is attached to the compression table 19, and includes an arm portion 41 that is displaced in the vertical directions F1 and F2 in conjunction with the expansion and contraction of the air suspension 7, and a rotation shaft 42 that is rotated in conjunction with the displacement of the arm portion 41. Have That is, the rotating shaft 42 rotates in conjunction with the expansion and contraction of the air suspension 7. Therefore, the rotation angle sensor 40 detects the contraction amount of the air suspension 7 based on the rotation angle of the rotation shaft 42.

  The rotation angle sensor 40 is driven by a power supply voltage output from the USB cable C. Moreover, in this embodiment, although the rotation angle sensor 40 is used, in the case of implementation, it is not necessary to limit to this rotation angle sensor 40, and other detection parts may be used.

  In the above structure, a learner who learns chest compression performs chest compression by placing a hand on the position of the compression table 19 of the simulated chest 3A of the human body model housing 1 and repeating the compression.

  When the learner presses the compression table 19, the compression table 19 is pressed against the air suspension 7 by the compression force, and the air suspension 7 is contracted in the downward direction F1. On the contrary, when the learner stops the compression, the air suspension 7 extends in the upward direction F <b> 2 and pushes up the compression table 19. The detection signal output from the rotation angle sensor 40 is input to the control board 25 via the cable 64.

  Here, in this embodiment, an air suspension 7 using the elasticity of air A is used instead of the coil spring. Therefore, every time the learner presses the simulated chest, the air suspension 7 does not generate a stretching sound. Further, when the learner strongly presses the simulated chest, the air suspension 7 does not generate a mechanical contact sound.

  Further, the compression of the sternum by the expansion and contraction of the air suspension 7 provides a realistic feeling close to that of the human body, compared to the compression of the sternum by the expansion and contraction of the coil spring.

  Therefore, according to the human body model for resuscitation training T1 of this embodiment, the learner can experience chest compression that achieves a reduction in noise generated during chest compression training and a real feeling close to the human body.

  Moreover, if the leaf spring 17 has a rectangular cross section as in this embodiment, the spring wires are less likely to contact each other than a spring having a circular cross section. Therefore, according to the resuscitation training human body model T1 of this embodiment, it is possible to reduce noise generated during chest compression training while using the elastic force of the leaf spring 17.

  In this embodiment, the air inside the human body model housing 1 flows in and out through the plurality of air holes 6 every time the learner presses the simulated chest 3A. Therefore, in the human body model housing 1 of this embodiment, the air pressure inside the human body model housing 1 does not increase or decrease every time the learner presses the simulated chest 3A.

  Therefore, in the resuscitation training human body model T1 of this embodiment, every time the learner presses the simulated chest 3A, high-pressure air is generated in the gap between the human body model housing 1 (for example, the joint between the epidermis 4 and the simulated back 2). ) Through and out. That is, there is no inflow sound or outflow sound of high-pressure air.

  Therefore, according to the resuscitation training human body model T1 of this embodiment, it is possible to further reduce noise generated during chest compression training.

  In this embodiment, the vent hole 6 is provided at the location of the simulated back portion 2 facing the simulated chest portion 3A. However, the present invention is not limited to this. At the time of implementation, for example, a vent hole may be provided at the location of the simulated back 2 facing the simulated abdomen 3B.

  FIG. 6 is a block diagram showing a configuration of the control board 25 shown in FIG. FIG. 7 is a front view of the display unit 30, the speaker 31, and the operation unit 32 shown in FIGS.

  On the control board 25, a microcomputer (hereinafter referred to as a microcomputer) 70, a DRAM 83, an audio output circuit 81, a flash memory 82, and the like are mounted. The control board 25 is connected to the USB port 39, the rotation angle sensor 40, the speaker 31, the operation unit 32, and the display unit 30.

  The display unit 30, the audio output circuit 81, the amplifier A2, and the speaker 31 correspond to the “notification unit” of the present invention. The USB port 39 corresponds to the “transmission unit” of the present invention. The rotation angle sensor 40 corresponds to a “detection unit” of the present invention, and the microcomputer 70 corresponds to a “compression depth detection unit”, a “compression tempo detection unit”, and a “return position detection unit” of the present invention.

  A USB cable C is connected to the USB port 39. The power supply voltage output from the USB cable C is supplied to each unit mounted on the control board 25 and peripheral devices connected to the control board 25.

  The microcomputer 70 controls the operation of each unit mounted on the control board 25 and the operation of peripheral devices connected to the control board 25. The microcomputer 70 includes an AD converter 71, a timer circuit 72, a CPU 73, a ROM 74, an SRAM 75, an SPI (Serial Peripheral Interface) 76, a clock circuit 77, a GPIO (General Purpose Input / Output) 78, and the like. Is incorporated.

  The microcomputer 70 is connected to a DRAM 83 as a work field for expanding data processed by a control program stored in the ROM 74.

  The audio output circuit 81 is configured by an LSI, for example, and is connected to the flash memory 82. The flash memory 82 stores voice data related to the start guidance, voice data related to the end guidance, voice data indicating an ideal compression tempo for pressing the heart, and the like.

  The audio output circuit 81 reads each audio data from the flash memory 82 in accordance with an instruction instructed from the SPI 76 of the microcomputer 70. The audio output circuit 81 performs DA conversion on the read audio data based on the clock signal output from the clock circuit 77, and outputs the audio data to the speaker 31 via the amplifier A2. The speaker 31 emits sound based on the sound data.

  The audio output circuit 81 is driven by the power supply voltage output from the USB cable C. The speaker 31 is also driven by the power supply voltage output from the USB cable C.

  As shown in FIG. 7, the display unit 30 is provided with a plurality of light emitting diodes L1 to L20 and a three-color light emitting diode L21. The microcomputer 70 drives the light emitting diodes L1 to L20 and the three-color light emitting diode L21 from the GPIO 78 via the driver D.

  In this embodiment, when the learner is performing chest compressions, the display unit 30 represents the compression depth of the simulated chest 3A by the number of lighting of the light emitting diodes L1 to L20. For example, as the compression depth is increased by 4 mm, the light emitting diodes are turned on sequentially from L1, and the number of light emitting diodes L1 to L20 is increased. FIG. 7 shows that the compression depth is 52 mm.

  Further, when the learner is performing chest compression, the display unit 30 indicates whether the compression depth of the simulated chest 3A is appropriate, too shallow, or too deep. Display by turning on blue and red. The display unit 30 is driven by a power supply voltage output from the USB cable C.

  In this embodiment, whether the compression depth of the simulated chest 3A is appropriate, too shallow, or too deep is indicated by lighting the green, blue, and red colors of the three-color light emitting diode L21. However, it is not limited to this. In implementation, the display may be performed by lighting other display methods, for example, blue, yellow, and red.

  The operation unit 32 is for a learner to input various commands to the microcomputer 70. A command input by the learner to the microcomputer 70 is transmitted to the microcomputer 70. The operation unit 32 includes a plurality of switches such as a first switch key for switching the operation time to either 30 seconds or 60 seconds, a second switch key for switching the operation mode to either the practice mode or the evaluation mode, and a volume key. A key (both not shown) is provided.

In addition, the learner can operate the volume key in the operation unit 32 to adjust the gain of the amplifier A2.
The operation unit 32 is driven by a power supply voltage output from the USB cable C.

  FIG. 8 is a flowchart showing an operation performed by the microcomputer 70 shown in FIG. 6 in the practice mode. This operation is performed when the learner selects either 30 seconds or 60 seconds with the first switching key of the operation unit 32 and selects the practice mode with the second switching key of the operation unit 32.

  First, the microcomputer 70 instructs the audio output circuit 81 to reproduce the start guidance (S1). Thereby, the audio output circuit 81 reads out audio data related to the start guidance from the flash memory 82 and outputs the start guidance from the speaker 31.

  The start guidance is, for example, “Start training. Place your hand in the middle of the chest and start chest compressions in time with the tempo.”

  When the reproduction of the start guidance is completed, the microcomputer 70 instructs the audio output circuit 81 to reproduce the tempo sound, starts the timer of the timer circuit 72, and starts the chest compression practice (S2).

  Then, the microcomputer 70 starts monitoring the compression depth of the simulated chest 3A, the compression tempo of the simulated chest 3A, and the return position of the simulated chest 3A (S3). The audio output circuit 81 reads tempo sound data indicating an ideal compression tempo that compresses the heart from the flash memory 82 and outputs the tempo sound from the speaker 31.

  Thereafter, the learner performs chest compression by placing a hand on the position of the compression table 19 of the simulated chest 3A of the human body model housing 1 shown in FIGS. 2 to 5 while listening to the tempo sound output from the speaker 31. . When the learner performs chest compressions, the amount of contraction of the air suspension 7 is detected by the rotation angle sensor 40. The detection signal output from the rotation angle sensor 40 is amplified by the amplifier A1 of the control board 25 and input to the microcomputer 70.

  The microcomputer 70 performs AD conversion on the input detection signal by the ADC 71, and calculates the compression depth of the simulated chest 3A based on the digitally converted value (that is, the rotation angle of the rotation angle sensor 40). The compression depth of the simulated chest 3 </ b> A corresponds to the contraction amount of the air suspension 7. Then, each time the learner presses the simulated chest 3A of the human body model housing 1, the microcomputer 70 lights up the light emitting diodes L1 to L20 corresponding to the number of lightings corresponding to the compression depth of the simulated chest 3A (see FIG. 7). .

  The microcomputer 70 compares the calculated compression depth of the simulated chest 3A with the ideal compression depth recorded in advance in the ROM 74, and the calculated compression depth of the simulated chest 3A is appropriate, too shallow, or too deep. Judge which one corresponds. Then, each time the learner presses the simulated chest 3A of the human body model housing 1, the microcomputer 70 displays the determination result on the three-color light emitting diode L21 of the display unit 30 (see FIG. 7).

  The ideal compression depth varies depending on the age of the human body (newborn, child, adult) and the like. Therefore, in this embodiment, the ideal compression depth is recorded in the ROM 74 in advance. However, in the implementation, a compression depth setting key for accepting the setting of the ideal compression depth may be provided in the operation unit 32. . In this case, the microcomputer 70 compares the calculated compression depth of the simulated chest 3A with the ideal compression depth set by the compression depth setting key, and the calculated compression depth of the simulated chest 3A is appropriate, too shallow, or too deep. It is determined which of the following is true.

  Further, the microcomputer 70 performs AD conversion on the input detection signal by the ADC 71 and returns it when the compression of the compression table 19 of the simulated chest 3A is released based on the digitally converted value (that is, the rotation angle of the rotation angle sensor 40). Calculate the position. The return position of the simulated chest 3 </ b> A corresponds to the contraction amount of the air suspension 7.

  Here, in ideal chest compression, it is necessary to return the simulated chest 3A to the original position for each chest compression. Therefore, the microcomputer 70 determines whether the return position when the learner releases the compression to the simulated chest 3A is more than a predetermined length from the original position on the simulated back 2 side at each chest compression. The predetermined length is, for example, 10 mm.

  When it is determined that the return position is on the simulated back part 2 side by a predetermined length or more from the original position, the microcomputer 70 notifies the speaker 31 that the return position at the time of releasing the pressure is incomplete. The output circuit 81 is instructed.

  Furthermore, the microcomputer 70 counts the number of times of compression of the simulated chest 3A for a predetermined time (5 seconds in this embodiment) based on the value obtained by AD-converting the detection signal output from the rotation angle sensor 40. The microcomputer 70 measures a predetermined time with the timer circuit 72.

  Then, the microcomputer 70 calculates the compression tempo of the simulated chest 3A, which is the number of compressions of the simulated chest 3A per unit time (in this embodiment, 1 minute). Then, the microcomputer 70 determines which range the calculated compression tempo of the simulated chest 3A belongs to within a preset range (S5, S6).

  In this embodiment, the range of the compression tempo is set in advance, but is not limited to this. At the time of implementation, a compression tempo setting key for accepting the setting of the compression tempo range may be provided on the operation unit 32. In this case, the microcomputer 70 determines which range the compression tempo of the simulated chest 3A belongs to within the range set by the compression tempo setting key.

  When the compression tempo of the simulated chest 3A is in the range of 100 times / minute or more and less than 120 times / minute, the microcomputer 70 instructs the audio output circuit 81 to notify the speaker 31 that the compression tempo is appropriate (S7). ).

  On the other hand, when the compression tempo of the simulated chest 3A is 120 times / minute or more, the microcomputer 70 instructs the audio output circuit 81 to notify the speaker 31 that the compression tempo is fast (S8).

  On the other hand, when the compression tempo of the simulated chest 3A is less than 100 times / minute, the microcomputer 70 instructs the audio output circuit 81 to notify the speaker 31 that the compression tempo is slow (S9).

  When the timer of the timer circuit 72 has passed the aforementioned operation time (for example, 60 seconds) (Y in S4), the microcomputer 70 ends the practice of chest compressions (S10). Specifically, the microcomputer 70 ends the reproduction of the tempo sound and the monitoring of the compression depth, the compression tempo, and the return position.

  Then, the microcomputer 70 instructs the audio output circuit 81 to reproduce the end guidance (S11). Thus, the audio output circuit 81 reads out audio data related to the end guidance from the flash memory 82 and outputs the end guidance from the speaker 31. The termination guidance is, for example, “Successful cardiopulmonary resuscitation. Great result.”

  Note that an ideal pattern indicating an ideal compression tempo, compression depth, and return position in chest compression is recorded in the ROM 74 shown in FIG. The microcomputer 70 compares the compression tempo, compression depth, and return position performed by the learner with the ideal pattern, and compares the compression tempo, compression depth, and return position that the learner performed with the chest compression training. To evaluate.

  Finally, the microcomputer 70 transmits the training data indicating the compression depth of the simulated chest 3A calculated by the microcomputer 70, the compression tempo of the simulated chest 3A, and the return position of the simulated chest 3A to the personal computer 90 via the USB cable C. (S12).

  As described above, the learner can know the compression tempo, the compression depth, the return position, and the evaluation position of the compression performed in the chest compression training from the display unit 30, the speaker 31, and the personal computer 90 during and after the training. it can. Therefore, according to the human body model T1 for resuscitation training of this embodiment, the learner's skill in chest compression can be dramatically improved.

  In this embodiment, the resuscitation training human body model T1 and the personal computer 90 are connected by the USB cable C, but the present invention is not limited to this. During implementation, for example, the resuscitation training human body model T1 and the personal computer 90 are equipped with a short-range wireless communication function (such as Bluetooth (registered trademark)), and the resuscitation training human body model T1 finishes training for chest compressions. Then, the training data may be transmitted to the personal computer 90 by wireless communication.

  In this case, the resuscitation training human body model T1 is connected to a commercial power supply and is driven by a power supply voltage output from the commercial power supply instead of the USB cable C. Alternatively, in this case, the resuscitation training human body model T1 includes a battery and is driven by a power supply voltage output from the battery instead of the USB cable C.

  FIG. 9 is a flowchart showing an operation performed by the microcomputer 70 shown in FIG. 6 in the evaluation mode. This evaluation mode is a mode in which reproduction of a tempo sound or the like is prohibited assuming actual chest compression, and is a mode performed by a learner or a medical worker who has completed chest compression practice in the practice mode. Therefore, the evaluation mode is a mode closer to actual chest compression than the practice mode.

  9 is an operation in which S2 and S10 shown in FIG. 8 are replaced with S22 and S30 and S7 to S9 are deleted, and the other processes (S1, S3 to S6, S11, and S12) are the same. It is. Therefore, differences from the operation shown in FIG. 8 will be described below.

  In the evaluation mode, when the reproduction of the start guidance is finished, the microcomputer 70 prohibits the reproduction of the tempo sound and starts the timer of the timer circuit 72 to start the evaluation of the chest compression (S22).

  In the evaluation mode, the microcomputer 70 also prohibits notification that the compression tempo is appropriate, that the compression tempo is fast, that the compression tempo is slow, and that the return position when the compression is released is incomplete.

  When the timer of the timer circuit 72 passes the above-described operation time (for example, 60 seconds) (Y in S4), the microcomputer 70 ends the evaluation of chest compressions (S30). Specifically, the microcomputer 70 ends the monitoring of the compression depth, the compression tempo, and the return position.

  Finally, also in the evaluation mode, the microcomputer 70 personalizes the training data indicating the compression depth of the simulated chest 3A calculated by the microcomputer 70, the compression tempo of the simulated chest 3A, and the return position of the simulated chest 3A via the USB cable C. It transmits to the computer 90 (S12).

  As described above, the learner and the medical staff can know the compression tempo, compression depth, return position, and evaluation position of the training performed in the chest compression training on the personal computer 90 after the training is completed.

  Therefore, according to the human body model T1 for resuscitation training of this embodiment, the effect of the learner's chest compression training can be confirmed. Moreover, according to the human body model T1 for resuscitation training of this embodiment, the chest compression skill of a medical worker can be confirmed.
