JP 2005-46382 A

  In order to increase the measurement accuracy of biological information by the biological information detection means, the user needs to press the finger pad and palm in a stable state against the biological information detection means. That is, if the finger pad or palm moves away from the biological information detection means or moves during the measurement, the measurement may not be performed properly or the measurement accuracy may be distorted.

  For this reason, if the measurement of biological information is performed during the operation of the massage means for staking or hitting the backrest or seat of the chair type massage machine, the upper body of the user is moved up and down, left and right by the massage means. Therefore, accurate measurement cannot be performed because the finger pad or palm rises from the biological information detection means.

  Therefore, it is possible to stop all the massage means while measuring the biological information, but it is difficult for the user to wait for the time required for the measurement (about 30 seconds) while the user is seated. Often considered a long waiting time.

  The purpose of the present invention is to measure the biological information of a patient by measuring only the massage that is less affected by the movement of the user's upper body when measuring the biological information of the user. It is to provide a chair type massage machine that makes it difficult for the user to feel that it is waiting time.

In order to solve the above problems, the chair type massage machine of the present invention is
A seat on which a user sits, a backrest disposed at the rear end of the seat, and a leg unit that is disposed at the front end of the seat and accommodates the legs of the user;
The seat part and / or the backrest part includes massage means for massaging the affected area of the user, and the leg unit includes leg massage means for massaging the leg of the user, and massage means And a chair-type massage machine having control means for controlling the massage means for the legs,
Electrically connected to the control means, comprising biological information detection means for measuring the biological information of the user,
When the biological information of the user is measured by the biological information detection means, the control means operates only the leg massage means without operating the massage means.

The chair type massage machine of the present invention is
A seat on which the user sits, and a backrest deployed at the rear end of the seat,
In a chair-type massage machine having an air bag for massaging the affected area of the user and / or massage means consisting of kneading balls that move up and down along the spine, and having control means for controlling the massage means. ,
Electrically connected to the control means, comprising biological information detection means for measuring the biological information of the user,
When the biological information of the user is measured by the biological information detecting means, the control means operates only the massage by inflating the airbag or the massage that moves the kneading balls up and down along the back muscles.

According to the chair type massage machine of the present invention, only the leg massage means is operated when detecting biological information. Alternatively, massage by inflating an airbag provided in the backrest or massage that moves the kneading balls up and down along the back muscles is performed.
Since these massages are massages that do not easily shake or vibrate the upper body of the user, the detection part of biological information, for example, the finger pad, is not affected by vibration or the like. Therefore, biological information can be detected with high accuracy.
In addition, the user does not feel this time as a waiting time by performing massage on the legs by the leg massage means during the time required for measuring the biological information.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a chair type massage machine (10) to which the present invention can be applied. In the chair type massage machine (10), a seat part (12) on which a user sits is swingably supported by a base part (11) placed on a floor surface. On the rear end side of the seat part (12), the backrest part (14) on which the back of the user hits, and on the front end side of the seat part (12), the leg unit for accommodating the leg part of the user (16) is supported.
As shown in FIG. 1, the leg unit (16) has recesses (17) and (17) for inserting the legs (portions below the knee) of the user.

  The seat part (12), the backrest part (14), and the leg unit (16) can be tilted with respect to the base part (11) by a reclining mechanism (not shown in FIG. 1). . The reclining mechanism has a structure in which the seat (12), the backrest (14), and the leg unit (16) are tilted independently by a plurality of actuators, etc., or a single actuator and a link mechanism are combined. Thus, the seat (12), the backrest (14), and the leg unit (16) can be tilted in cooperation.

  In addition, on the left and right sides of the seat (12), elbow rests (18) and (18) that can be tilted integrally with the seat (12) are provided.

As shown in FIG. 1, the seat part (12), the backrest part (14), and the leg unit (16) have a seat part massage means (20) for massaging the user, respectively, as shown in FIG. Massage means (22) and leg massage means (24) are provided.
Examples of the seat massage means (20) include air bag type, vibration type and roller type massage means.
Moreover, as a backrest part massage means (22), an airbag type, a kneading ball type, a vibration type, and a roller type massage means can be illustrated. In the case of massaging ball type or roller type massage means, it can be moved up and down along the longitudinal direction of the backrest (14).

Examples of the leg massage means (24) include an airbag type, a vibration type, and a roller type. In order to suppress the influence of vibration or the like on the upper body of the user, it is desirable to use an airbag type.
When an airbag is used for the leg massage means (24), as shown in FIG. 1, one or more airbags are provided on the inner surface of the recess (17) and the bottom surface of the recess (17), respectively. It is desirable to be able to massage the calf, ankle and toe of the user by expanding and contracting the bag.

The elbow rests (18) and (18) are respectively provided with biological information detection means (30) for measuring biological information of the user. An example of the biological information measured by the biological information detecting means (30) is a heartbeat.
When measuring a heartbeat as biological information, a pair of electrodes can be exemplified as the biological information detecting means (30). The electrode is disposed on the upper surface on the front end side of the elbow rest (18) (18). In this position, with the user sitting on the seat (12), place the arm of the user (the part beyond the elbow) on the elbow rest (18) (18) so that the palm faces downward In this case, a position where the index finger and the middle finger touch or a position where the palm touches is used.
By providing the biological information detecting means (30) at this position, the user can touch the biological information detecting means (30) in a natural state without being particularly conscious, and feel tired during the measurement. There is nothing.
By detecting the potentials of the left and right hands using the biological information detection means (30) and measuring the potential difference with the control means (50), the heart rate of the user can be measured.

FIG. 2 shows an example of a heartbeat waveform detected by the biological information detection means (30). In the figure, the fluctuation of the heartbeat of the user can be determined by detecting the fluctuation width (CVRR) of the interval between the protruding portions (R wave) of the heartbeat waveform. The fluctuation width (CVRR) is detected by a fluctuation detection circuit (32) (see FIG. 3) electrically connected via the biological information detection means (30) and the control means (50).
The smaller the fluctuation width (CVRR) detected by the fluctuation detection circuit (32), the higher the degree of wakefulness of the user and the more stressed state is. The larger the fluctuation width (CVRR), the more the user is treated. Means less stressed and relaxed.

  When measuring and detecting the body temperature of the user as biological information, a temperature sensor can be used as the biological information detection means (30), and when measuring and detecting a pulse, biological information detection A photosensor may be used as the means (30).

The operation of the chair type massage machine (10) is performed by a controller (40) disposed on one of the elbow rests (18) as shown in FIG.
The controller (40) includes a plurality of operation buttons for selecting a power switch, a massage course, a massage point, a massage strength, and the like. In addition, the controller (40) includes massage information such as the selected massage course, the operation state, position, strength, and elapsed time of the massage means (20), (22) and (24), and biological information detection means (30). The display part which displays the biometric information detected by this is provided.

  In order to enhance the massage effect, the seat (12), the backrest (14) and / or the leg unit (16) is provided with a heater (60) (described later) at an appropriate place to heat the affected area. A warming massage by action can be applied.

  FIG. 3 is a block diagram of a control system of the chair type massage machine (10) of the present invention. All control of the chair type massage machine (10) is performed by the control means (50). The control means (50) is composed of a microprocessor or the like, and has a memory (not shown) for storing various control programs, massage programs, and the like.

  As shown in FIG. 3, the control means (50) includes a controller (40), a biological information detection means (30), a fluctuation detection circuit (32), massage means (20) (22) (24), a reclining mechanism ( 28) and the heater (60) are electrically connected, and operate based on an operation command from the controller (40) and a program stored in advance in the control means (50).

  The massage means for the seat (20), the massage means for the backrest (22), and the massage means for the leg (24) are motor-driven (for example, roller type, kneading ball type), the control means (50) Are connected via a motor drive circuit. When the massage means is an airbag type, an air pump and a valve are electrically connected to the control means (50) to control the expansion and contraction of the airbag.

The reclining mechanism (28) is also connected to the control means (50) via a motor drive circuit in the case of motor drive.
The reclining mechanism (28) tilts the seat (12), the backrest (14), and the leg unit (16) to a desired angle based on a command from the control means (50).

  The heater (60) is on / off controlled based on an operation of the controller (40) of the user or a massage course program.

A massage course including biometric information detection of the chair type massage machine (10) having the above configuration will be described with reference to a flowchart of FIG.
In the chair type massage machine (10), the present invention can satisfactorily maintain the contact state between the finger pad or palm of the user and the biological information detecting means (30) when detecting the biological information. In addition, the user is given a massage that minimizes swinging, vibration, and movement of the upper body of the user.
As a massage for suppressing the swinging of the upper body, in the following examples, the massage to the leg by the leg massage means (24) is illustrated during the biometric information detection.
In this embodiment, the heart rate is exemplified as the biological information, and the heart rate measurement is performed at the beginning and the end of the massage course. However, the biological information is not limited to the heart rate, and the measurement timing is also limited to the following. Is not to be done.

  First, the user sits on the seat (12), operates the controller (40) to turn on the chair-type massage machine (10) (step 1), and operates a desired massage course including measurement of biological information. The button is operated (Step 2). Then put both hands on the elbow rest (18) (18). In a state where the user places both hands on the elbow rests (18) and (18), the finger pad or palm of the user naturally comes into contact with the biological information detecting means (30).

When the control means (50) detects that the user's finger pad or palm touches the biological information detection means (30), the massage course starts (steps 3 and 4).
The massage course is started by first detecting biometric information (heartbeat) by the biometric information detection means (30) and massaging the leg of the user by the leg massage means (24) (step 4). According to this step, since the massage is performed only on the legs of the user during the biological information detection, the upper body of the user does not swing, move, etc., so that the arm is in a stable state. The biological information detecting means (30) is maintained in a good contact state with the finger pad or palm of the user, and accurate biological information can be detected.

  The potential measured by the biological information detection means (30) is transmitted to the control means (50) to detect the heartbeat by the potential difference, and the fluctuation width (CVRR) is detected by the fluctuation detection circuit (32). The obtained heart rate and fluctuation width (CVRR) are stored in the memory of the control means (50) and displayed as numerical values and / or graphs on the display unit of the controller (40) (step 5).

  After a predetermined time (for example, 30 seconds), the biological information detection means (30) detects the heartbeat of the user (step 6), the biological information detection means (30) detects the heartbeat, and the leg massage means (24 ) Is stopped (step 7), and the whole body massage is performed using the massage means for the seat (20), the massage means for the backrest (22), and the massage means for the leg (24). (Step 8). When the whole body is massaged for the time set by the massage course (step 9), the massage means for the seat (20), the massage means for the backrest (22), and the massage means for the leg (24) Stop (step 10) and detect biometric information again.

Detection of the heart rate after the whole body massage is performed in the same manner as before the whole body massage.
That is, after the whole body massage is finished, when the control means (50) detects that the finger pad or palm of the user is in contact with the biological information detection means (30) (step 11), the biological information detection means ( 30) The biometric information (heartbeat) is detected and the leg massage means (24) is used to massage the leg of the user (step 12).
According to this step, since the massage is performed only on the legs of the user during the biometric information detection, the upper part of the user does not swing, move, or the like. It is maintained in a stable state, and a good contact state between the biological information detection means (30) and the finger pad or palm of the user is maintained, and accurate biological information can be detected.

  The potential measured by the biological information detection means (30) is transmitted to the control means (50) to detect the heartbeat by the potential difference, and the fluctuation width (CVRR) is detected by the fluctuation detection circuit (32). The obtained heartbeat and swing width (CVRR) are stored in the memory of the control means (50) and are displayed as numerical values and / or graphs on the display unit of the controller (40) (step 13).

  After a predetermined time (about 30 seconds), the heartbeat of the user is detected by the biological information detection means (30) (step 14), the heartbeat is detected by the biological information detection means (30), and the leg massage means (24 ) Stops the massage to the leg (step 15), and the massage course is completed.

  Compare the heart rate and swing width (CVRR) before the whole body massage measured in Steps 3 to 7 with the heart rate and swing width (CVRR) after the whole body massage measured in Steps 11 to 15. The degree to which the body is relaxed may be determined and displayed on the controller (40). Thereby, the user has an advantage that the degree of relaxation can be recognized not only by bodily sensation but also visually.

In the above description, when detecting biological information, only the leg massage means (24) is operated in order to suppress swinging, vibration, etc. of the upper body of the user. In the case where a massaging ball (roller) type is used as the massaging means (22) for the stagnation part, it is possible to perform massage only by the vertical movement of the massaging ball with less swinging of the upper body when detecting biological information. At this time, it is preferable to slow down the speed of the kneading balls, so that the upper body can be prevented from swinging.
In addition to this, as a massage with less swinging of the upper body, a pressure massage with a slow airbag on the waist and back can be mentioned, and this massage may be performed when detecting biological information.

Moreover, based on the biological information measured before the whole body massage, the stress level of the body of the user can be determined, and the strength, time, type, etc. of the massage can be changed during the whole body massage.
Specifically, when the stress is high, if the body is too stimulated, the massage effect may be reduced. To enhance it, you can apply a strong massage.
For example, if the massaging means (22) for the backrest uses a kneading ball, the strength of the massage can be adjusted by changing the protrusion amount and the moving speed of the kneading ball.

Furthermore, the tilt angle of the seat (12), the backrest (14), and the leg unit (16) may be changed based on the biological information measured before the whole body massage.
For example, as schematically shown in FIGS. 5 (a) and 5 (b), when the stress is large, the backrest (14) is greatly inclined backward (FIG. 5 (a)), and the user lies down. You can be in a relaxed state and have a relaxing massage. On the other hand, when the stress is small, the backward inclination of the backrest (14) may be reduced (FIG. 5 (b)).

  Further, in the chair type massage machine (10) in which the heater (60) is provided in the seat (12), the backrest (14) and / or the leg unit (16), the heater (60 ) On and off, and the temperature may be controlled. For example, when the stress is large, turn on the heater (60), heat the affected area, and make a massage with a thermal effect to enhance the massage effect and shift the user to a relaxed state be able to.

When an airbag is used as the massage means (20) (22) (24), a heater (60) is provided on the surface of the airbag (preferably the surface on the side of the user), and is provided between the airbag and the air pump. As shown in the flow chart in FIG. 6, when the pressure sensor is provided in the electromagnetic valve or the pipe, the airbag is inflated, that is, when the electromagnetic valve is in the open state or the pressure sensor detects a pressure higher than a predetermined value. (Step 1) When the heater (60) is turned on (Step 4) and the airbag is deflated (Step 1), that is, when the electromagnetic valve is closed or the detected value of the pressure sensor becomes less than a predetermined value. By turning off the heater (60) (step 3), the heater (60) can be used efficiently and with energy saving. This is because the heater (60) is pressed against the user due to the inflation of the airbag, so that it can be warmed efficiently.
If the temperature of the heater (60) is equal to or higher than a predetermined temperature (for example, 43 ° C.), the heater (60) should be turned off even when the airbag is inflated to prevent further heating. (Step 2).
By repeatedly turning on and off the heater (60), there is an advantage that the heat of the heater (60) can be prevented from being applied to the same portion over a long period of time.

  In the above embodiment, in order to detect biological information, a biological information detecting means is provided on the left and right elbow rests, and a type of measuring by pressing the finger pad and palm placed on the elbow rest against the biological information detecting means. As described above, for the type that measures by grasping the living body information detection means with a hand, when detecting the living body information, the massage that operates only the leg massage means (24) or the roller type (the kneading balls) When using the type), increase the measurement accuracy by applying massage that moves the kneading balls slowly up and down along the back muscles, or massage that does not rock the upper body, such as pressure massage with an airbag on the waist or back. be able to. The type that measures by grasping with a hand is easier because the posture is not restrained.

  In addition, as the biological information detecting means, the one provided with two detection means on the left and right sides for measuring the heart rate has been described, but one biological information may be used depending on the biological information to be measured.

  The present invention is useful as a chair type massage machine capable of accurately measuring biological information such as a heartbeat of a user.
