To control.

  Specifically, biological information related to a heartbeat such as an electrocardiogram waveform and a pulse, and biological information related to an electroencephalogram (for example, an α wave) are detected as biological information related to the degree of relaxation. And the degree of relaxation is monitored by quantitatively calculating the degree of comfort of the user based on the biological information.

The degree of comfort used in each of the following embodiments as the degree of relaxation is calculated based on the following equation.
(Expression 1) Comfort level = A × heart rate + B × degree of fluctuation + C × α wave + D
However, A, B, C, and D are coefficients. The “fluctuation degree” used in calculating the comfort level based on the above equation is the geometric figure analysis of the time domain analysis based on the biological information about the heartbeat. Calculated using the method.

[First Embodiment]
1. Overview of Lorentz Plot First, the Lorentz plot, which is one of the indexes representing the degree of fluctuation, will be briefly described. The Lorentz plot is known as a method for evaluating the enhanced state of the sympathetic nerve and the parasympathetic nerve. In general, it is important that the sympathetic nerve and the parasympathetic nerve are balanced. If the balance between the sympathetic nerve and the parasympathetic nerve is disturbed, fluctuations in pulsation (heart rate) are affected.

  The Lorentz plot is obtained by visualizing fluctuations of the heartbeat based on biological signals such as an electrocardiogram waveform and a pulse.

  FIGS. 13 and 14 are diagrams showing a method of generating a Lorentz plot based on an electrocardiographic waveform. When an electrocardiographic waveform as indicated by 1301 in FIG. 13 is collected, the position of the R wave is first identified, and the RR interval is calculated. The R wave refers to the peak portion of the electrocardiogram waveform, and the RR interval refers to the heartbeat interval of the nth beat (n is an arbitrary integer) and the n + 1th beat of the R wave. In the example of FIG. 10, the R wave positions are identified as R1, R2, R3, and R4, respectively, and the RR intervals are calculated as T21, T32, and T43, respectively.

  Then, based on the calculated RR interval, T32 is plotted on the horizontal axis and T21 is plotted on the vertical axis in the two-dimensional graph region shown in FIG. Further, T43 is plotted on the horizontal axis and T32 is plotted on the vertical axis. A Lorentz plot is generated by sequentially performing such processing on successive RR intervals.

  The degree of fluctuation is calculated as the size of the distribution region in the two-dimensional graph region of the generated Lorentz plot (that is, variation in Lorentz plot data).

  For reference, FIG. 15 shows an example of the generated Lorentz plot. (A) generally shows a good balanced state, (b) and (c) show an unbalanced state ((b) shows stress / disease patterns, (c) shows Each showing an arrhythmia pattern).

6). Flow diagram of the process in the measurement unit 120. 5 is a flowchart showing the flow of the measurement process in the measurement unit 120.

  In step S501, the display mode is determined. The display mode is for specifying the type of data displayed on the data display unit 401. In the case of the massage apparatus 100 according to the present embodiment, there are a Lorentz plot display mode and a trend display mode. If the Lorentz plot display button 403 is pressed, the Lorentz plot display mode is determined, and the process proceeds to step S502. On the other hand, if the comfort level display button 404 is pressed, the trend display mode is determined, and the process proceeds to step S517.

  In step S502, the Lorentz plot display screen (FIG. 4) is displayed. Further, in step S503, it is confirmed whether or not a measurement end instruction has been issued (confirms that the measurement start / end button 402 has not been pressed again). If a measurement end instruction has not been issued, the process proceeds to step S504.

  In step S504, it is determined whether or not the heartbeat detection processing unit 321 has received heartbeat measurement data. In the case of the massage device 100 according to the present embodiment, since the electrode 306 is built in the measurement unit 120, an electrocardiographic waveform can be detected while the user holds the measurement unit 120 at the implantation position. However, if one hand leaves during massage, the electrocardiogram waveform cannot be detected. Therefore, in step S504, it is monitored whether or not heart rate measurement data can be received for a predetermined time.

  If it is determined in step S504 that heart rate measurement data has not been received, the process proceeds to step S509, and reception is performed from the start of counting “predetermined time” until it is determined that heart rate measurement data has not been received. Delete the measured heart rate data. In step S510, the timer for counting “predetermined time” is reset. Further, in step S511, the display of the Lorentz plot on the data display unit 401 is reset, and the Lorentz plot displayed from the start of counting for a predetermined time until it is determined that the heartbeat measurement data cannot be received is deleted.

  On the other hand, if it is determined in step S504 that the heartbeat measurement data has been received, the process proceeds to step S505, where the heartbeat measurement data received by the heartbeat detection processing unit 322 and the brain wave input are received by the heartbeat detection processing unit 321. The electroencephalogram measurement data received by the processing unit 327 is acquired.

  In step S506, the R wave of the acquired heartbeat measurement data is identified, and the heart rate per unit time (for example, per minute) is calculated. The display processing unit 323 blinks a heart rate detection mark (described later) on the Lorentz plot display screen in accordance with the identified R wave, and displays the calculated heart rate in a heart rate display column (described later).

  In step S507, Lorentz plot is performed. In step S508, it is determined whether or not a predetermined time has elapsed since the timer was started. If the predetermined time has not elapsed, the process returns to step S501.

  As a result, if a display mode switching instruction is given before the predetermined time elapses, the screen is switched accordingly, and there is a case where the user's 130 hand leaves the electrode 306 before the predetermined time elapses. As a result, the display of the Lorentz plot displayed halfway will be reset.

  Until a predetermined time elapses, a predetermined display (segment display or the like, countdown display or countup display) is performed at an arbitrary position on the data display unit 401, and pets, children, landscapes, characters, etc. are arbitrarily set It is also possible to perform screen display so as to select and sequentially complete an image or the like.

  If it is determined in step S508 that the predetermined time has elapsed, the timer stops counting and the process proceeds to step S512. In step S512, the reception of the heart rate measurement data is temporarily terminated, and the degree of fluctuation is calculated and displayed using the Lorentz plot data calculated so far. Preferably, in step S513, a line indicating the Lorentz plot data distribution area is calculated and displayed.

  In step S514, the electroencephalogram measurement data when a predetermined time has elapsed is displayed.

Further, in step S515, the comfort level of the user 130 is calculated based on the electroencephalogram measurement data acquired in step S505, the heart rate detected in step S506, and the degree of fluctuation calculated in step S512. To do. In calculating the comfort level, the following formula is used.
(Expression 1) Comfort level = A × heart rate + B × degree of fluctuation + C × α wave + D
However, A, B, C, and D are coefficients. FIG. 6 is a diagram illustrating an example of a Lorentz plot display screen of the data display unit 401 before a predetermined time has elapsed. In the figure, 601 is a heart rate detection mark, and 602 is a heart rate display column. Reference numeral 603 denotes a column indicating whether the data display unit 401 is currently enlarged, displayed in a standard size, or reduced. Reference numeral 604 denotes a field for displaying the current date and time.

  Returning to FIG. In step S516, the comfort level calculated in step S515 is output to the control unit 111. After outputting the comfort level, after resetting the timer, the process returns to step S501.

  On the other hand, if it is determined in step S501 that the display mode is the trend display mode, the process proceeds to step S517, and a trend display screen is displayed. Further, in step S518, it is confirmed whether or not a measurement end instruction has been issued (confirms that the measurement start / end button 402 has not been pressed again). If a measurement end instruction has not been issued, the process proceeds to step S519.

  In step S519, it is determined whether the heartbeat detection processing unit 321 has received heartbeat measurement data. If it is determined in step S519 that the heartbeat measurement data cannot be received, the process proceeds to step S522, and reception is performed from the start of the “predetermined time” count until it is determined that the heartbeat measurement data cannot be received. Delete the measured heart rate data. In step S523, the timer for counting “predetermined time” is reset.

  On the other hand, if it is determined in step S519 that the heartbeat measurement data has been received, the process proceeds to step S520, where the heartbeat interval detection processing unit 322 receives the heartbeat measurement data and the brain wave input received by the heartbeat detection processing unit 321. The electroencephalogram measurement data received by the processing unit 327 is acquired.

  In step S521, the R wave of the acquired heartbeat measurement data is identified, the heart rate per unit time (for example, per minute) is calculated, and Lorentz plot data is calculated.

  In step S524, it is determined whether or not a predetermined time has elapsed since the timer was started. If the predetermined time has not elapsed, the process returns to step S501. On the other hand, if it is determined in step S524 that the predetermined time has elapsed, the timer count is stopped, and the process proceeds to step S525.

  In step S525, the reception of the heart rate measurement data is temporarily terminated, and the degree of fluctuation is calculated using the Lorentz plot data calculated so far. Further, in step S526, the degree of comfort of the user 130 is determined based on the electroencephalogram measurement data acquired in step S520, the heart rate calculated in step S521, and the degree of fluctuation calculated in step S525. calculate.

  In step S527, the calculated comfort level is plotted on the trend graph display screen.

  FIG. 8 is a diagram illustrating an example of a trend display screen of the data display unit 401, where the horizontal axis represents time and the vertical axis represents comfort level (%). In the figure, reference numeral 800 denotes a trend graph of comfort level.

  Returning to FIG. In step S528, the calculated comfort level is output to the control unit 111. After outputting the comfort level, after resetting the timer, the process returns to step S501 again.

  If it is determined in step S502 or step S518 that the measurement start / end button 402 has been pressed again, the process proceeds to step S529, the display of the data display unit 401 is reset, and the process ends.

  Thus, in the massage apparatus 100 according to the present embodiment, when the measurement start / end button 402 is pressed once, the measurement process shown in FIG. 5 is repeated until the measurement start / end button 402 is pressed next. Executed.

  In other words, the massage apparatus 100 repeatedly performs a process of receiving heart rate measurement data / electroencephalogram measurement data for a predetermined time, acquiring heart rate / Lorentz plot data, calculating fluctuation degree, and calculating comfort level. Will be done.

  FIG. 9 shows the display of the data display unit 401 when the measurement process is executed according to the flowchart shown in FIG.

  In FIG. 9, reference numeral 901 denotes reception / non-reception of heartbeat measurement data. When the measurement start / end button 402 is pressed (902), reception and non-reception of heart rate measurement data are alternately repeated. In the Lorentz plot display mode, each heart rate measurement received within a predetermined time is received. A Lorentz plot is performed based on the data, and the heart rate, the degree of fluctuation, and the degree of comfort during that time are calculated and displayed (see each screen shown in 904). In the trend display mode, the heart rate calculated based on each heart rate measurement data received within a predetermined time, the degree of fluctuation, and the comfort level calculated based on the electroencephalogram measurement data are plotted. Go (see each screen shown in 905). Note that when the display mode is switched by pressing the Lorentz plot display button 403 or the comfort level display button 404, the screen indicated by 904 in FIG. 9 and the screen indicated by 905 are switched. When the measurement start / end button 402 is pressed again, the process is terminated (903).

In the manual mode, an operation instruction is given to the drive unit 1006 based on an instruction input from the user 130 via the operation I / F unit 1005.

Reference numeral 1013 denotes a data receiving unit that receives the comfort level transmitted from the measuring unit 120 and passes it to the massage operation control unit 1011.

8). Configuration of Operation Unit 114 FIG. 11 is a diagram showing a configuration of the operation unit 114. As shown in the figure, the operation unit 114 can be roughly divided into an area for specifying an operation mode, an area for specifying an operation content, and an area for specifying an operation position.

  An automatic mode designation button 1101 and a manual mode designation button 1102 are arranged in the area for designating the operation mode. When the automatic mode specification button 1101 is specified, the massage operation control unit 1011 determines an operation instruction based on the comfort level transmitted from the measurement unit 120 and performs a massage operation.

  On the other hand, when the manual mode specification button 1102 is specified, the massage operation control unit 1011 performs a massage operation according to the contents specified in the region for specifying the operation content and the region for specifying the operation position.

  As described above, in the manual mode, the operation content, the operation intensity, and the operation position can be arbitrarily combined.

9. Flow of Processing in Control Unit 111 Next, the flow of massage operation processing in the control unit 111 when the automatic mode is designated will be described. When the automatic mode is designated, execution of the flowchart shown in FIG. 12 is started.

  In step S1201, it is determined whether or not the comfort level is received from the measurement unit 120. The user 130 presses the automatic mode designation button 1101 and then presses the measurement start / end button 402 of the measurement unit 120 to start detection of an electrocardiogram waveform and an electroencephalogram. As a result, the comfort level calculated by the measurement unit 120 is transmitted to the control unit 111.

  In step S1201, when the comfort level is not received, the process ends. On the other hand, if it is determined in step S1201 that the degree of comfort has been received, the process proceeds to step S1202, and it is determined whether the specified time has elapsed. The specified time is assumed to be set in the control unit 111 in advance. Every time the specified time elapses, the massage operation control unit 1011 of the control unit 111 reviews the operation content, the operation intensity, and the operation position, and changes the direction so that the comfort level is improved.

  In step S1203, it is determined whether or not the comfort level has increased from the previous time (before the specified time). If it is determined that the degree of comfort has increased from the previous time (before the specified time), the process proceeds to step S1207.

  On the other hand, if it is determined that the comfort level is equal to or decreased from the previous time (before the specified time), the process proceeds to step S1204, and it is determined whether or not the operation content can be changed. Here, in the massage operation control unit 1011, when the comfort level has not increased when the specified time has elapsed, the operation content is sequentially changed. For this reason, when all the operation contents are executed for the specific operation position, it is determined in step S1204 that the operation cannot be changed. On the other hand, if there is an operation content not yet executed, it is determined in step S1204 that the operation can be changed, and the process proceeds to step S1205.

  In step S1205, the operation content is changed. The change of the operation content is assumed to be performed in the order of, for example, “fir” → “tap” → “stretch” → “stirp” → “acupressure” → “vibration”. However, it goes without saying that the order is not limited to this.

  On the other hand, if it is determined in step S1204 that the operation content cannot be changed, the process advances to step S1206 to determine whether the operation position can be changed.

  If it is determined in step S1206 that the operating position can be changed, the process advances to step S1207 to change the operating position. Note that the movement position is changed in the order of “foot” → “butt” → “waist” → “back” → “shoulder” → “hand”, but the order is limited to this. It goes without saying that it is not done.

  In step S1207, it is determined whether or not the comfort level has reached the target value. If it is determined in step S1208 that the comfort level has not reached the target value, the process returns to step S1201. On the other hand, if it is determined that the comfort level has reached the target value, the process is terminated.

  As is clear from the above description, the massage device according to the present embodiment detects an electrocardiogram waveform and an electroencephalogram, and uses the heart rate, the degree of fluctuation, and the electroencephalogram calculated based on the electrocardiogram waveform to comfortably. The degree was calculated and displayed. As a result, the user can recognize the presence or absence of the relaxation effect during the massage.

  Furthermore, the massage apparatus according to the present embodiment is configured to sequentially change the operation content and the operation position of the massage operation so that the calculated comfort level increases. This makes it possible to selectively execute a massage having a relaxation effect.
