FIG. 12 shows another example of conditions for determining whether or not to return to the normal state.

  In the storage unit E, as described above, the consultation state detection signal output from the consultation state detection unit C of the pseudo patient body, the evaluation reference information used in the training result evaluation calculation unit F, and the wearing state determination unit N It stores pseudo-biological signal data that mimics biological signals, along with various data and control programs necessary for practical training, such as criteria information used, training scenarios to be described later, patient information set, contraindication information for commonly used drugs, etc. As the simulated biological signal data, a plurality of patterns of simulated biological signals as shown in FIG. 7 are stored.

  Specifically, in the present embodiment, as a pseudo biological signal, blood pressure measured by the sphygmomanometer 51, pulse, oxygen saturation measured by the pulse oximeter 52, cardiac potential measured by the electrocardiograph 53, and myoelectric potential I remember it.

  Furthermore, for various pseudo-biological signals, the age classification is child, adult and elderly, the basic disease classification is heart disease, hypertension, diabetes, etc. The represented pseudo-biological signal is stored.

  Furthermore, in addition to the above-described classification, pseudo-biological signals representing the characteristics of each normal time and abnormal time are stored. In addition, about the time of abnormality, the reaction of each drive part for performing drive control based on the biological reaction at the time of the said abnormality generation | occurrence | production is memorize | stored.

  Specifically, as shown in FIG. 8, assuming a hyperventilation syndrome as an abnormal mode state example indicating an abnormal state, a display example of a normal mode pseudo-biological signal in a normal state and a pseudo-biological signal in an abnormal state are displayed. The display example and the reaction example regarding the operation of the simulated patient body 2 in the abnormal mode are stored.

  First, when switching from the normal mode to the abnormal mode, the systolic blood pressure and diastolic blood pressure decrease, the pulse rate, blood oxygen saturation, respiration rate, and mental sweating increase. And is stored in the storage unit E as a pseudo-biological signal in an abnormal mode.

  Further, as an example of the reaction of the pseudo patient body 2 in the abnormal mode, the eyelid 24b is opened so as to open the pseudo eyeball 26, the head 2a is turned up with the jaw model 23 opened, and the hand of the upper limb 2c is placed on the chest. The pseudo patient body drive unit D is set to execute the operation of moving the body part 2b up and down quickly and vigorously and stored in the storage unit E.

  Assuming tachycardia as another abnormal mode state example, as shown in FIG. 9, the systolic blood pressure, the diastolic blood pressure, the pulse rate, the respiratory rate, and the amount of mental sweating increase, and the electrocardiogram waveform becomes faster. In addition, it is set so as to swing up and down, and is stored in the storage unit E as another pseudo biological signal in the abnormal mode.

  Further, as an example of the reaction of the simulated patient body 2 when tachycardia is assumed in the abnormal mode, the simulated patient body drive unit D performs an operation to move the simulated eyeball 26 left and right and up and down and close the jaw model 23. It is set to be executed and stored in the storage unit E.

  Further, in the abnormal mode set in the training, the storage unit E has a normal mode for dealing with the trainee Z when an abnormality occurs based on the medical condition detection signal output from the medical condition detection unit C of the simulated patient body. The condition change determining unit P stores the condition for determining whether or not to return to.

  Specifically, as shown in FIG. 10, the following six conditions (treatments) are stored as condition examples for determining whether or not to return to the normal mode based on the medical condition acquired by the diagnosis state detection unit C. Yes.

  Condition 1 is that the drive signal of the medical instrument 1d has been turned off (the trainee Z stops the treatment), and Condition 2 is that the angle sensor of the jaw model 23 returns to the initial value (when closed) (practice) The person Z stops the treatment and closes the jaw model 23), and the condition 3 is that the voice such as “is it all right” is recognized by the voice detecting microphone or the like (the person Z trains) Yes, condition 4 is that the tilt signal in the tilt direction of the examination table 3 is turned on (the chair of the examination table 3 is tilted by the operation of the trainee Z), and condition 5 is “ "Close your mouth and breathe slowly through your nose" and so on (recognizing nasal breathing (compound breathing)), and condition 6 is to detect the passage of a predetermined time after stopping the treatment (rest Is stored as a condition. When these six conditions are satisfied, the state change determination unit P is configured to determine that the normal mode should be restored.

Conversely, for example, a condition for determining whether the state change determination unit P determines whether or not to shift from the normal mode to the abnormal mode by the treatment in the training will be described.
As shown in FIG. 11, the following six examples are stored in the storage unit E as condition examples for determining whether or not the abnormal mode should be set based on the medical condition acquired by the consultation status detection unit C.

Condition 1 is that the patient (pseudo-patient body 2) is set to be a patient with hypertension in the setting at the start of the program, etc., and condition 2 is incorporated in the jaw model 23 constituting the mouth. It is detected that the open state of the jaw model 23 exceeds a predetermined time based on the output of the angle sensor that detects the degree of opening of the lower jaw, and condition 3 is based on the output of the angle sensor. It is detected that the opening state of the jaw model 23 is larger than a predetermined angle, and condition 4 is that based on the pressure sensor of the tooth 23d, it is detected that a pressure exceeding a predetermined value is applied by cutting with a strong force. Condition 5 is that excessive cutting was detected by a conduction sensor provided on the tooth 23d and detecting the amount of cutting (the resistance value of electricity conducted to the tooth 23d due to excessive cutting was reduced). The condition 6 is a condition that the temperature sensor provided in the tooth 23d detects that the temperature exceeds a predetermined temperature due to friction caused by cutting. I remember it.
Note that the state change determination unit P is configured to determine that the abnormal mode should be set when two or more of the conditions 2 to 6 are satisfied in addition to the condition 1.

  Furthermore, the storage unit E stores conditions for the state change determination unit P to determine whether or not to return to the normal mode with respect to the action of the trainee Z in the abnormal mode that has shifted from the normal mode by the treatment in the training. Yes.

Specifically, as shown in FIG. 12, the following six conditions (treatments) are stored as condition examples for determining whether or not to return to the normal mode based on the medical condition acquired by the consultation status detection unit C. Yes.
Condition 1 is that the drive signal of the medical instrument 1d has been turned off (the trainee Z stops the treatment), and Condition 2 is that the angle sensor of the jaw model 23 returns to the initial value (when closed) (practice) The person Z stops the procedure and closes the jaw model 23), and the condition 3 is to recognize the voice such as “Is it all right” with a voice detecting microphone or the like (condition is 4) Is that the tilting signal in the standing direction of the examination table 3 is turned ON (the chair of the examination table 3 is raised by the operation of the trainee Z), and the condition 5 is water injection for the water injection of the cup provided in the spitton 12 A sensor (a switch for detecting whether or not water has been injected) is turned ON, and condition 6 is to detect the passage of a predetermined time after stopping the treatment (to make the patient rest). When these six conditions are satisfied, it is determined that the normal mode should be restored.

Subsequently, training using the medical training device T configured as described above will be described with reference to FIGS.
FIG. 13 is a flowchart showing processing as the main processing unit, FIG. 14 is a schematic diagram of the patient information setting unit, FIG. 15 is a flowchart showing processing of an abnormality occurrence scenario, and FIG. 16 is a biological signal measurement processing. It is a flowchart to show. 17 and 18 are flowcharts showing another biological signal measurement process.

First, in the main process of the training, the PC main body 40 accepts the setting of patient information.
Specifically, for example, patient information is set using an operation setting screen 100 as shown in FIG.
The patient information set on the operation setting screen 100 as shown in FIG. 14 is the screen of the display unit 42 shown in FIG. 1 and the operation screen operated by the training instructor who teaches the instructor Z. The scenario display unit 101, training situation expansion display unit 102, training situation display unit 103, age group setting unit 110, common medicine setting unit 120, constitution setting unit 130, gender setting unit, training content setting unit and scenario changing unit not shown It consists of.

  The scenario display unit 101 is a part in which a training scenario generated by an operation described later is displayed in text, and the training situation enlargement display unit 102 zooms in and displays the face of the simulated patient body 2 receiving the training, The training status display unit 103 is a portion that displays the training status of the upper body of the simulated patient body 2 and the training person Z.

  The age group setting unit 110 includes an elderly patient setting unit 111, an adult patient setting unit 112, and a child patient setting unit 113. The common drug setting unit 120 includes a no common drug setting unit 121, a warfarin setting unit 122, and a bisphosphonate drug setting unit 123. The constitution setting unit 130 includes a non-specific constitution setting unit 131, an allergy setting unit 132, and a pregnant woman setting unit 133.

  On the operation setting screen 100, the training instructor specifies the patient mode by operating any one of the elderly patient setting unit 111, the adult patient setting unit 112, and the child patient setting unit 113 of the age group setting unit 110. , Any one of the no-medicine setting unit 121, the warfarin setting unit 122, and the bisphosphonate drug setting unit 123 of the common-medicine setting unit 120, the non-specific constitution setting unit 131, the allergy setting unit 132, and the pregnant woman setting unit 133 of the constitution setting unit 130. By operating any of the above, it is possible to set the patient information of the patient assumed in the practice.

The patient information is set on the operation setting screen 100 configured as described above. However, a setting item may be appropriately set according to the training content such as a disease type setting unit.
Next, the PC body 40 accepts the scenario selection (step S2). The instruction for scenario selection is performed, for example, by the training instructor selecting the scenario displayed on the display unit 41 through the operation unit 43. Here, the scenario is information in which actions (including utterances) performed by the practitioner Z or the practitioner Z and the patient in the medical practice (medical practice) are arranged in time series. Interview scenario, treatment scenario in which the trainee Z touches the patient model in the treatment and examines the medical condition using a device, etc., and the treatment scenario related to the treatment that treats the affected area specified by the medical interview and examination Etc. are assumed.

When the scenario selection is accepted in step S2, the PC main body 40 executes the selected scenario in the next step S3.
After step S3, in step s4, the PC body 40 notifies the evaluation of the practice obtained by the practice result evaluation calculation unit F. The notification of evaluation is performed by displaying on the display units 41 and 42. However, the notification of evaluation may be configured to be performed by an output device such as a printer provided separately so as to be communicable with the PC main body 40.

  In step S5, it is determined whether or not the history data during scenario execution is to be reproduced. Whether or not to reproduce is determined according to an instruction through the operation unit 43 such as a keyboard or a mouse. If it is determined that reproduction is not necessary, the process ends. If it is determined that reproduction is necessary, the process proceeds to step S6.

  In step S6, history data during scenario execution is reproduced. The various history data to be reproduced is at least a part of imaging data of actions included in the scenario, evaluation data, data of each medical condition detection signal acquired by the medical condition detection unit C, and the like. Thereby, the apprentice Z can review his / her actions. Thereafter, the process is terminated.

Next, an abnormal mode process that becomes an abnormal mode in the execution of the scenario in step S3 in the main process described above will be described.
In the abnormal mode process, generally, it is determined whether or not the abnormal mode should be set according to a predetermined condition, and when it is determined that the abnormal mode should be set, the display for the practitioner that is the biological information display unit This is a process for displaying the pseudo biological signal indicating the abnormal mode on the unit 42.

  That is, in step T1, the PC main body 40 determines whether or not the abnormal state should be set by the state change determination unit P. The determination as to whether or not to enter the abnormal mode is made based on whether or not the predetermined condition as described above is satisfied. The determination as to whether or not the predetermined condition is satisfied is performed based on the medical condition acquired by the medical condition detection unit C. However, regardless of the medical condition, the state change determination unit P is determined probabilistically. There may be.

  In addition, when determining whether or not to enter the abnormal mode based on the medical condition acquired by the medical examination state detection unit C, patient information (for example, the patient's constitution, temperament, etc.) set at the start of practical training, etc. The determination may be made in consideration of the above.

  If it is determined in step T1 that the state change determination unit P should shift to the abnormal mode (step T1: YES), the simulated patient body driving unit D performs an abnormality such as the reaction example shown in FIG. Drive control is performed so as to achieve the state operation (step T2).

  Conversely, when it is determined in step T1 that the mode is not the abnormal mode but the normal mode (step T1: NO), the biological signal output unit L outputs a normal pseudo biological signal as shown in step T9. Or you may end the practice as it is.

  When the wearing state detection unit M detects that the measuring instrument 5a (513, 523, 533) is attached to the biological signal measurement location X by the trainee Z who has confirmed the abnormal operation in Step T2 (Step T3: YES) Then, the mounting state determination unit N determines the mounting state (step T4).

  If the wearing state determination unit N determines that the wearing state of the measuring instrument 5a is abnormal (step T4: NO), the training may be terminated, but a warning that the wearing state is not normal may be displayed. Good.

  When it is determined by the mounting state determination unit N that the mounting state of the measuring instrument 5a is normal (step T4: YES) and the measurement start is detected by the measurement start detection unit O (step T5: YES), The biological signal output unit L outputs (displays) the abnormal biological signal in the abnormal mode to the display units 41 and 42 as shown in the display example in the abnormal state in FIG. 8 (step T6).

  When the state change determination unit P determines the countermeasure or treatment by the student Z who has confirmed the display of the abnormal pseudo-biological signal and determines that the abnormal mode should be maintained (step T7: NO), the process returns to step T2. Drive control is performed so that the simulated patient body drive unit D operates in an abnormal state.

  Conversely, if the state change determination unit P determines that the mode should be changed to the normal mode (step T7: YES), the pseudo patient body drive unit D performs drive control so as to obtain a normal reaction (step T8), and the living body. The signal output unit L outputs (displays) the pseudo biological signal in the normal mode (step T9).

  Next, an output process in which the biological signal output unit L displays a pseudo biological signal in steps T3 to T6 and T9 described above will be described with reference to FIG. 16 as a specific example of blood pressure measurement using the sphygmomanometer 51.

  First, when the cuff 513 is attached to the biological signal measurement point Xc1, the attachment of the cuff 513 is detected by the attachment sensor S that is attached to the biological signal measurement point Xc1 and functions as the attachment state detection unit M (step U1). When the measurement start button 515 provided on the sphygmomanometer body 511 of 51 is pressed by the trainee Z (step U2), the sphygmomanometer 51 is driven by a pump built in the sphygmomanometer body 511. Air is supplied to the cuff 513 through the connection tube 512 (step U3).

  The mounting sensor S that has detected an increase in tightening pressure due to the supplied air functions as a measurement start detection unit O, transmits a detection result of detection of measurement start to the control unit I, and is controlled by the control unit I. The signal output unit L selects and outputs a pseudo biological signal based on the set patient information (step U4), and displays the selected pseudo biological signal on the display unit 514 provided in the sphygmomanometer body 511.

  Even if the mounting sensor S does not function as the mounting state detection unit M, the training instructor visually confirms the mounting of the cuff 513 to the biological signal measurement location Xc1, as shown in FIG. May be transmitted to the control unit I as the cuff 513 attachment detection information (step U1a).

  Further, without causing the mounting sensor S to function as the mounting state detection unit M and the measurement start detection unit O, as shown in FIG. 18, the training instructor visually confirms (step U1a), and the information processing device 4 May be transmitted to the control unit I as measurement start detection information (step U2a).

  Further, in the steps from Step U1 (U1a) to U4, the wearing state determination unit N is operated to attach the cuff 513, and press the measurement start button 515 and information for instructing the measurement start. Even if there is an input operation of the operation unit 43 of the processing device 4, when the mounting state by the mounting state determination unit N is not normal, the biological signal output unit L does not output the pseudo biological information in step U4. Also good.

  Thus, the medical training device T controls the driving of the simulated patient body 2 having the trunk 2b, the head 2a, the upper limb 2c, and the lower limb 2d, and the simulated patient body driving unit D equipped in the simulated patient 2 A control unit I, an operation unit 43 connected to the control unit I, a measurement instrument 5a that can be attached to a biological signal measurement point X that measures a biological signal, and a measurement start detection unit that detects a measurement start by the measurement instrument 5a O and the measurement start detection unit O detects the start of the pseudo measurement, and thus includes the biosignal output unit L that outputs a pseudo biosignal imitating the biosignal, so that the measurement start detection unit O detects the measurement start. Thus, in order to output the simulated biological signal to the biological signal output unit L, for example, air is supplied to the tube in the pulsating motion device of the simulated patient body formed of a foam having a skin layer on the surface, and the like is pulsated. Requires complex structure Without, though, it can be performed using a pseudo patient body 2 having a simple structure and training such as measuring biological signals using the biological signal measuring Kigu 5 having a measuring instrument 5a.

  In addition, the apparatus includes a mounting state detection unit M that detects the mounting of the measuring instrument 5a at the biological signal measurement location X, and the biological signal output unit L detects the start of pseudo measurement by the measurement start detection unit O and the mounting state detection unit. Since the pseudo-biological signal is output when the measurement instrument 5a is detected by M, it is assumed that the measurement start button 515 of the sphygmomanometer 51 is pressed in a state where the measurement instrument 5a is not attached to the biological signal measurement location X. However, the biological signal output unit L does not output a pseudo biological signal.

  In addition, the apparatus includes a mounting state determination unit N that determines the mounting state of the measuring instrument 5a at the biological signal measurement location X, and the biological signal output unit L detects the start of pseudo measurement by the measurement start detection unit O and the mounting state detection unit. Since the pseudo-biological signal is output by detecting the mounting of the measuring instrument 5a by M and the normal mounting determination of the measuring instrument 5a by the mounting state determination unit N, the measuring instrument 5a is temporarily mounted at the biological signal measurement location X. Even if the measurement start button 515 of the sphygmomanometer 51 is pressed in a state where there is not, the biological signal output unit L does not output a pseudo biological signal. As described above, the medical training device T has a simple structure by using the configuration in which the biological signal output unit L outputs the pseudo biological signal, but as if using the measuring instrument 5a, the biological signal measuring instrument 5 and the like. Although it is possible to perform practical training such as measuring a biological signal, the biological signal output unit L does not output unless the measuring instrument 5a such as the measuring instrument 5a is normally attached to the biological signal measurement location X. Practical training can be conducted in line with medical practice.

If only the data is output, the countermeasure or treatment for the symptom is determined, so that the apprentice Z does not have to perform the act of confirming the output pseudo-biological signal and considering the countermeasure that must be performed. However, when a pseudo biological signal selected from a plurality of pseudo biological signals stored in the storage unit E is output, the trainee Z determines whether the output pseudo biological signal is normal or abnormal, or abnormal. Pseudo If a biological signal, deal in accordance with the symptoms need to think about something, it is possible to perform a reality in line with the actual medical practice.

  Further, the pseudo patient body drive unit D drives at least one of the jaw model 23, the pseudo eyeball 26, the eyelid 24b, the neck 27, and the upper limb 2c, or a combination of two or more thereof, for example, blinking The patient's response to coping with the trainee Z can be expressed by eye movements such as changing the eye direction, and so on, so that hands-on training can be performed more realistically according to actual medical treatment. Note that a configuration in which a cheek portion or eyebrows that control an expression is driven may be used.

  In addition, a voice recognition / output unit 21f for listening and recognizing the voice of the trainee Z and a voice recognition / output unit 21f for outputting the voice of the simulated patient are configured to be capable of simulated conversation with the trainee Z. It is possible to conduct practical training with a more realistic feeling, such as reproducing patient interviews and interactions with patients.

  When an abnormal mode that imitates an abnormal state is set, the biological signal output unit L outputs a simulated biological signal that simulates a biological signal in an abnormal state, and the simulated patient body drive unit D and / or audio. Since the recognition / output unit 21f controls behavior and voice in an abnormal state, in the actual medical treatment, it is very important in the medical treatment of acquiring a biological signal when an abnormality occurs and diagnosing the state based on the symptom and the biological signal. Can practice practical medical practice.

  Moreover, when the state change determination part P is provided with the state change determination part P which determines pass / fail about the countermeasure which the practitioner Z performed, and the state change determination part P makes a pass determination about the countermeasure of the practitioner Z when the abnormal mode is set, the abnormal mode The biological signal output unit L outputs a simulated biological signal that imitates a normal biological signal, and the simulated patient body driving unit D and / or the voice recognition / output unit 21f By configuring the drive to simulate the normal state and / or to output the sound that simulates the normal state, in the actual medical care, a biological signal is acquired when an abnormality occurs, and the state is diagnosed based on the symptom and the biological signal. When the countermeasures taken based on the diagnosis result are suitable, it is possible to practice a situation in the medical treatment where the situation is improved.

  Also, a scenario set by the scenario setting unit b of the simulated patient body setting operation unit G, which is stored in advance and includes a simulated patient body setting operation unit G that allows at least one scenario to be selected from a plurality of scenarios according to the training content. The control unit I controls the biological signal output unit L and the simulated patient body driving unit D according to the training content of the training, so that it is not a training practice in each scene as in the actual medical treatment. You can practice practical medical practices.

  Moreover, it is provided with the imaging part 1eb which images a training situation, and the memory | storage part E which memorize | stores the training situation imaging information imaged by the imaging part 1eb, and is instruct | indicated practice by comprising so that practice situation imaging information can be reproduced | regenerated.
