(Embodiment)
Hereinafter, an embodiment of a massage machine will be described with reference to the drawings.

As shown in FIG. 1, the massage machine 10 includes a massage machine main body 11, a treatment unit 12, an operation unit 13, and a control unit 14.
The massage machine main body 11 includes a seat portion 21 that supports the buttocks of the user (the user), a backrest portion 22 that supports the back surface of the user, an ottoman 23 that supports the user's lower limbs, The armrest 24 is provided on both the left and right sides and extends in the front-rear direction Z. An upper limb cover 25 that approaches and separates from the armrest 24 is rotatably attached to a front portion of the armrest 24.

  The treatment part 12 includes a back treatment part 12a attached to the inside of the backrest part 22, a lower limb treatment part 12b attached to the inside of the ottoman 23, and an upper limb treatment part 12c attached to the inside of the armrest 24 and the upper limb cover 25. And have. An example of the back treatment unit 12a performs massage with the treatment element 36, and examples of the lower limb treatment unit 12b and the upper limb treatment unit 12c are airbags.

  The back treatment unit 12a includes a treatment block 31 and a treatment element 36 (scrubbing balls). In the present embodiment, the treatment element 36 functions as a load applying unit that applies a load to the user when sensing the symptoms of stiffness.

As shown in FIG. 2, the treatment block 31 includes a vertical drive unit 32, a width drive unit 33, and a strength drive unit 34.
Each of the vertical drive unit 32, the width drive unit 33, and the strength drive unit 34 includes a position sensor that detects the position of the treatment element 36, a sensor that detects the speed of the treatment element 36, and motors M1, M2, and M3. I have.

  The vertical drive part 32 moves the treatment block 31 itself in the vertical direction Y of the massage machine 10 on a rail (not shown) provided in the backrest part 22 by the rotational driving force of the motor M1. The width driving unit 33 drives the treatment element 36 in the left-right direction X by the rotational driving force of the motor M2. The strength / weakness drive unit 34 operates the treatment element 36 in a direction in which the treatment element 36 is pressed against the back side of the user by the rotational driving force of the motor M3 and in a direction opposite to the pressing direction.

  The user is massaged by the operation of the treatment element 36 driven by the vertical drive unit 32, the width drive unit 33 and the strength drive unit 34. In addition, the vertical drive part 32, the width drive part 33, and the strength drive part 34 operate | move based on the signal from the treatment element control part 51 mentioned later.

The operation unit 13 includes a selection button for selecting one massage course from a plurality of massage courses, a start button for executing a massage course (both not shown), and the like.
The control unit 14 controls the operation of the treatment unit 12 based on the massage course selected by operating the operation unit 13.

  As shown in FIGS. 3 and 4, the massage machine 10 includes a biological physiological information measuring unit 40 as a biological information measuring unit that measures biological information that is information related to a living body that changes due to massage. The biological physiological information measuring unit 40 is attached to the armrest 24. Here, the biophysiological information measuring unit 40 measures an index related to stiffness, blood circulation, fatigue, pain, and the like related to the effect and effectiveness of the massage. In this embodiment, the biophysiological information measuring unit 40 measures skin electrical reflection (Galvanic Skin Response: GSR) related to the amount of sweat. Since sweating occurs when a part having stiffness or pain is treated, this amount of sweating can be used as biophysiological information. In this GSR information, electrodermal activity (EDA) and electrodermal reaction (EDR) are used. In the present embodiment, the biological physiological information measuring unit 40 calculates an electrodermal reaction (EDR) together with the amount of change in EDA. Then, the biological physiological information measuring unit 40 supplies GSR information (EDA, EDR) to the control unit 14.

As shown in FIG. 4, the biological physiological information measuring unit 40 of the present embodiment includes a first electrode 41 and a second electrode 42.
Each electrode 41, 42 in FIG. 4 has a plurality of convex portions 43 on its surface. Each protrusion 43 has conductivity, extends in the left-right direction X, and the protrusions 43 are arranged in a row with a predetermined gap. Each convex portion 43 extends so as to be continuous in the left-right direction X. The electrodes 41 and 42 are insulated from each other. For example, the upper limbs of the user come into contact with the convex portions 43 of the electrodes 41 and 42 to conduct. And since each electrode 41 and 42 conduct | electrically_connects, an electric current flows into the electrodes 41 and 42, Therefore The magnitude | size of the electric current at that time is measured in the biophysiological information measurement part 40, and the magnitude | size of measured current and palm The palm sweating amount (GSR information) is calculated by calculation using an arithmetic expression related to the sweating amount.

As shown in FIG. 3, the control unit 14 includes a treatment element control unit 51 and an evaluation unit 52.
The treatment element control unit 51 controls the vertical drive unit 32, the width drive unit 33, and the strength drive unit 34. In addition, the treatment element control unit 51 acquires information on the treatment position of the treatment element 36 from the position sensors provided in each of the vertical drive unit 32, the width drive unit 33, and the strength drive unit 34.

  The treatment element control unit 51 holds pattern information in which a massage pattern is recorded according to a massage course, for example, in its own memory (not shown). In the massage pattern, a plurality of places (sensing points) for grasping stiffness symptoms are set. Furthermore, the treatment element control unit 51 holds information on the load force used for grasping stiffness symptoms. As the load force, a plurality of loads (low load, high load, etc.) are used according to the stiffness symptoms.

  Furthermore, the treatment element control unit 51 holds information related to treatment contents to be performed according to stiffness symptoms. In the present embodiment, the information regarding the tender point treatment pattern and the cure treatment pattern is held as the treatment content. Furthermore, when the stiffness symptom cannot be resolved by the treatment of the tender point treatment pattern and the induration treatment pattern, adjustment information for correcting the treatment content (procedure and power) is held.

As shown in FIG. 2, the treatment element control unit 51 is connected to a force detection unit 61 and a physique detection unit 62.
The force detection unit 61 detects a physical quantity that the treatment element 36 receives from the user. Here, the distance from the center of the treatment element 36 to the user when the surface of the treatment element 36 is in contact with the user and is not deformed is referred to as a “reference distance”. The difference between the reference distance and the reference distance when approaching the user is defined as the “displacement amount” of the treatment element 36. The displacement amount when the treatment element 36 is at the reference position is “0”. Further, the distance from the backrest 22 to the center of the treatment element 36 is defined as the “projection amount” of the treatment element 36. Furthermore, the magnitude of the force for pressing the treatment element 36 against the user is defined as the “pressing force” of the treatment element 36. And the force detection part 61 detects the repulsive force (load force) from the user at the time of massage as a mechanical physical quantity according to pressing force.

  As the force detector 61, for example, a strain gauge or a measuring device that measures the displacement of an elastic body can be used. Then, the force detection unit 61 outputs a load force detection signal detected by the treatment element 36 to the treatment element control unit 51.

  In addition, the physique detection unit 62 detects the general physique of the user. To detect this physique, first, the user sits on the seat portion 21 and leans against the backrest portion 22 and moves the treatment element 36 in the vertical direction while pressing the treatment element 36 against the user, so that the position of the shoulder or waist Determine. The position of the shoulder or waist is determined by a method of determining from the position in the front-rear direction when the treatment element 36 is moved in the vertical direction while keeping the force received by the treatment element 36, or in the vertical direction while maintaining a constant position in the front-rear direction. The method of judging from the force at the time of moving to is mentioned.

  Moreover, the detection with respect to the left-right direction of a body is also possible with the same structure. Specifically, since the human body has a convex shape with the spine (center) at the top in the left-right direction of the back, if the position is changed away from the spine in the left-right direction, the force that presses the user is reduced. .

As shown in FIG. 3, the evaluation unit 52 includes a treatment site determination unit 71, a biological state evaluation unit 72, and an evaluation result storage unit 73.
The treatment site determination unit 71 acquires information (position information) about the position where the treatment element 36 is operating from the treatment element control unit 51. And the treatment site | part discrimination | determination part 71 specifies a treatment site | part based on this positional information. Further, the treatment site determination unit 71 acquires the load force (physical quantity information) in the treatment element 36 from the treatment element control unit 51.

  The biological state evaluation unit 72 acquires information related to biological information. In the present embodiment, information (treatment site information, physical quantity information) acquired from the treatment element control unit 51 and GSR information (EDA, EDR) acquired from the biological physiological information measurement unit 40 are acquired. And the biological condition evaluation part 72 evaluates the biological condition of a treatment site | part based on the acquired some biological information (here biophysiological information). Therefore, the biological state evaluation unit 72 holds biological state determination information for determining stiffness symptoms according to the magnitude of each load applied to the treatment element 36. In this biological state determination information, information related to a threshold for determining the size of biological information is set with respect to the size of load (for example, two types of low load and high load).

Furthermore, the biological state evaluation unit 72 displays the evaluation result (the determination result of the biological state and stiffness symptoms) on the display unit 13 a of the operation unit 13.
The evaluation result storage unit 73 records the result (biological state) evaluated by the biological state evaluation unit 72. The evaluation result storage unit 73 records the evaluation results before and after the massage for each treatment site.

(Relationship between biological physiological information and biological state)
The relationship between the biological physiological information (GSR information) detected by the biological physiological information measuring unit 40 and the biological state of the user will be described. Depending on the degree of autonomic nervous system activity, changes in GSR, skin temperature, and pulse rate vary.

  Here, when the activity is low, the GSR and the pulse rate decrease, and the skin temperature increases. When the activity is slightly low, the GSR is in a sideways state, but the skin temperature increases and the pulse rate decreases. When the activity is slightly high, the GSR rises from a sideways state, the skin temperature decreases, and the pulse rate increases. Furthermore, when the activity is high, the GSR increases greatly, the skin temperature decreases, and the pulse rate increases.

  As described above, the biological state of the user when the biological physiological information changes can be estimated as a relaxed and pleasant state when the activity is low. Further, when the activity is slightly high, it can be estimated that the biological state is a mixture of both “painful” and “comfortable”, which are unique emotions received when, for example, massaging a stiff portion. On the other hand, when the activity is high, it can be estimated that the person feels “pain”. Further, when the activity is neutral, it can be estimated that the neutral state is “no comfort or pain”.

Next, an operation example of the massage machine 10 according to the present embodiment will be described.
When the main power supply of the massage machine 10 is turned on, the AC power of the AC power supply is supplied to the control unit 14. The control unit 14 converts AC power into DC power by an AC / DC converter (not shown) built in the control unit 14. The control unit 14 supplies a voltage between the electrodes 41 and 42. The control unit 14 supplies a voltage between the electrodes 41 and 42 from when the main power supply of the massage machine 10 is turned on until the massage course selected by the operation unit 13 (see FIG. 1) is completed.

  Here, for example, when the upper limb is not placed on the surface (convex portion 43) of each of the electrodes 41 and 42, the electrode 41 and the electrode 42 are not electrically connected. For this reason, since the electric current which flows into the electrodes 41 and 42 becomes "0", the biological physiological information measurement part 40 does not measure the perspiration amount (biological information) of a palm. Thereby, the control unit 14 causes the treatment unit 12 to perform a massage operation based on the massage program selected by the operation unit 13.

  On the other hand, for example, when an upper limb is placed on the surface (convex portion 43) of each electrode 41, 42, a conductive state is established between each electrode 41, 42 via the palm. For this reason, a current flows between the electrodes 41 and 42. Then, the biological physiological information measuring unit 40 calculates the palm sweating amount (GSR information) by calculation using an arithmetic expression of the relationship between the current magnitude and the palm sweating amount at that time. The perspiration amount (GSR information) is output to the biological state evaluation unit 72. The biological state evaluation unit 72 evaluates the biological state of the treatment site based on the acquired plurality of sweating amounts (GSR information).

  Further, in the biological physiological information measuring unit 40 of the present embodiment, convex portions 43 are provided on the surfaces of the electrodes 41 and 42. For this reason, the convex part 43 can create a gap between the user and the biological physiological information measuring unit 40, and sweat can come into contact with air. As a result, it is possible to positively evaporate (remove) sweat generated by other than the stimulation of the treatment element 36 as a stimulation applying unit.

Next, the effect of this embodiment will be described.
(1) Since a gap can be interposed between the user and the biological physiological information measuring unit 40, the generated sweat is discharged from the biological physiological information measuring unit 40 or when the sweat comes into contact with air.
