The age of the user input by the age input unit is transmitted to the control means (50).

  The chair type massage machine (10) is provided with biological information detection means (30) for measuring biological information of the user. Examples of biological information measured by the biological information detecting means (30) include skin resistance and heart rate. These are respectively measured by a skin resistance detector (60) and a heartbeat detector (70) described later. Of course, the biological information to be measured is not limited to these, and may be body temperature, pulse rate, sweating amount, and the like.

For example, as shown in FIGS. 2 and 3, the biological information detection means (30) is a cylindrical auxiliary operation unit (see FIG. 2 and FIG. 3) provided with a plurality of electrodes (62), (72), (74), and (80) for detection. 42). The auxiliary operation unit (42) has an outer diameter (diameter of about 3 cm to 5 cm) that allows the user to grip the end of the auxiliary operation unit (42) with both hands, and the skin resistance detection unit (60 ), A second electrode 72 serving as a heart rate detector 70, a third electrode 80 serving as a ground, and a heart rate detector 70 provided at the other end. ) Has a fourth electrode (74) paired with the second electrode (72). The third electrode (80) for grounding is shared by the first electrode (62) and the second electrode (72).
More specifically, the second electrode (72) and the fourth electrode (74), which are the heartbeat detection unit (70), are respectively disposed near both ends of the circumferential surface along the axial direction of the auxiliary operation unit (42). The first electrode (62), which is the skin resistance detection unit (60), and the third electrode (80) for grounding are arranged side by side in the circumferential direction on the back side of the second electrode (72).

  The auxiliary operation unit (42) may perform a part of operations performed in the operation unit (40). In this case, as shown in FIG. 2, the operation buttons (44) and (46) may be disposed between the second electrode (72) and the fourth electrode (74), which are the heart rate detection unit (70). it can. As the operation buttons (44) and (46), for example, a reclining button (44) for operating a reclining mechanism (not shown), or a repeat button (46) for performing an operation command for repeatedly performing a currently performed massage operation It is desirable for the user to be able to perform only operations that are considered necessary during the massage. Thereby, in order for the user to operate the operation unit (40), it is not necessary to get up or reach out, and the massage is not hindered. In addition, by reducing the number of operation buttons on the auxiliary operation unit (42), the user does not need to look at the auxiliary operation unit (42) every time it is operated, which may hinder massage. Absent.

The biological information detection means (30) is not limited to the above, and may be directly disposed on the upper surfaces of the front ends of the elbow rests (18) and (18) as shown in FIG.

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.

  FIG. 4 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. 4, the control means (50) includes an operation section (40), an auxiliary operation section (42), a biological information detection means (30), massage means (20) (22) (24), a reclining mechanism. (28) is electrically connected, and based on the operation command from the operation unit (40) and / or the auxiliary operation unit (42) and the program stored in advance in the control unit (50), massage means ( 20) (22) (24) etc. operate.

  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).

Detection of the biological information of the user by the control means (50) can be performed as follows.
When measuring heart rate as biological information, the heart rate detection unit (70) detects the potential of the left and right hands, and measures the potential difference with the control means (50). Can be measured. Specifically, by measuring the above-described auxiliary operation unit (42) by the user, the first to third electrodes (62), (72), (80) are touched with one hand, Touch the fourth electrode (74) with the other hand.

FIG. 5 shows an example of a heartbeat waveform detected based on the potentials of the second electrode (72) and the fourth electrode (74) which are the heartbeat detection unit (70). The degree of stress is 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. 4) built in 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.

In the measurement of the heartbeat waveform, the strength of the received signal varies depending on individual differences (the position of the heart of the user).
Therefore, the reception sensitivity in the control means (50) is switched according to the strength of the signal detected by the heartbeat detection unit (70).
As shown in FIG. 4, the outputs from the second and fourth electrodes (72) and (74), which are the heart rate detection unit (70), are amplified (low gain) by the first amplifier (76), and control means ( 50), if the detected signal is smaller than a predetermined threshold value, the signal is further amplified (high gain) by the second amplifier (78) connected in series with the first amplifier (76) and controlled. Input to the means (50).
Thereby, even when the input signal is small, the control means (50) can receive a signal related to the heartbeat with a predetermined sensitivity.

The sensitivity switching is performed, for example, by reading the R wave peak of the CVRR value every 10 msec with respect to the low gain input value, calculating a moving average every 100 msec (10), and averaging the values. In order to perform peak detection for the 10 input values used for the moving average, when the fifth value is a measured value and the measured value is greater than 2.5V, “input value −2.5V” When the measured value is 2.5 V or less, the moving average value for 1 second (100 pieces) is calculated as “2.5 V-input value” to obtain a rectified value.
If the calculated low gain rectified value is equal to or higher than a predetermined threshold, for example, 0.2 V or higher, the control means (50) adopts the heart rate signal obtained by the low gain, and the low gain rectified value is predetermined. If it is smaller than the threshold value, a high-gain heartbeat signal further amplified by the second amplifier 78 is adopted.

  As described above, by automatically switching the sensitivity based on the magnitude of the signal related to the measured heartbeat, it is possible to prevent the heartbeat waveform from being determined to be impossible due to the magnitude of the heartbeat signal.

  The CVRR value obtained above generally has a characteristic that the standard value decreases as the age increases. By age group, the standard value is 4.0 for those under 40 years old, but it is 3.0 for those 40 to 60 years old, and 2.6 for those 60 and over.

  As shown in FIG. 6, for a CVRR value whose standard value changes according to age, a stress table for the CVRR value for each age band is created, and the criterion for determining the degree of stress is switched according to age. And the massage course given to a user is set with respect to the age band and the measured CVRR value.

  In FIG. 6, a massage course 1 is a massage course for a user having a high CVRR value, that is, low stress. As a massage course, a massage centered on acupressure can be exemplified, whereby the acupressure points of the affected area of the user can be activated, and the massage course gives a strong stimulus to the affected affected area. This course has a strong activity effect but a low relaxation effect.

  The massage course 2 is an intermediate-strength massage course and can be a hit-centered massage course. This massage course is a little unsatisfactory for patients with strong stiffness and has a low massage effect, but can relax the affected area against a wide range of weak stiffness. This course has a relaxing effect due to the weak vibration caused by tapping.

  The massage course 3 is a massage course for a user who has a low CVRR value, that is, a strong stress. As a massage course, a weak massage course can illustrate a massage course centering on itching, for example. This massage course is the least stimulating course and has a high relaxing effect. This massage course offers a relaxing massage, allowing the user to relax mentally.

  The massage course using the stress table of FIG. 6 can be performed according to the flowchart shown in FIG.

When the user selects this massage course by operating the operation unit (40), the age input to the age input unit is requested (step 1). In this state, the auxiliary operation unit (42) is grasped with both hands. Thus, a heartbeat waveform is detected based on the potentials of the second electrode (72) and the fourth electrode (74) of the heartbeat detection unit (70), and the CVRR value is measured by the control means (50) ( Step 2).
At this time, if the output of the heartbeat waveform is small, the output is performed with a high gain by the above sensitivity switching.
The control means (50) determines the stress level based on the obtained CVRR value and the age input in Step 1 (Step 3), and selects a massage course by referring to the stress table based on the stress level. (Step 4).
When the massage course is selected, the control means (50) performs massage corresponding to the massage course to the user (step 5).

  As described above, the CVRR value that varies depending on the age of the user can be corrected, the stress level can be determined, and the optimal massage course for the user's age, mental fatigue level, etc. can be automatically selected, and the optimal Massage can be given.

  Further, as the stress level based on the CVRR value and the biometric information, the skin resistance of the user is further measured to determine the stiffness level of the user, and based on the stress level and stiffness level, massage is performed. You can also choose a course.

  The skin resistance of the user is a measure of the amount of perspiration of the user when the massage is performed. The stiffness is weak, that is, the lower the stiffness level, the less the perspiration, the skin resistance detection unit Since the current flowing between the first electrode (62) and the third electrode (80), which is (60), decreases and the amount of perspiration increases as the stiffness increases, the first electrode (62) and the third electrode Current flowing between (80) tends to increase.

The skin resistance is measured by grasping the finger of one hand of the user to touch the first electrode (62) and the third electrode (80) arranged on one end side of the auxiliary operation unit (42). Can be done.
A signal relating to the skin resistance obtained by the first electrode (62) is transmitted to the control means (50) and used for determination of the stiffness level.
The control means (50) classifies the stiffness level into 1 to 8 stages based on the signal relating to the skin resistance obtained from the first electrode (62) which is the skin resistance detector (60). Stiffness level 1 indicates a state in which the stiffness is the weakest, and the stiffness increases as the stiffness level increases.

  FIG. 8 shows a table for selecting a massage course (described above) according to the stiffness level and the stress level described above. As shown in the figure, when the stress level is the same, the stronger the stiffness level, the stronger the stimulation (the aforementioned massage course 1) is selected. When the stiffness level is the same, the greater the stress level, the more the stimulation level. A weak massage (the aforementioned massage course 3) is selected.

  The massage course using the table of FIG. 8 can be performed according to the flowchart shown in FIG.

When the user selects this massage course by operating the operation unit (50), the second electrode (72) and the fourth electrode of the heart rate detection unit (70) are held by grasping the auxiliary operation unit (42) with both hands. Based on the potential of the electrode (74), a heartbeat waveform is detected, and the CVRR value is measured by the control means (50) (step 1).
At this time, if the output of the heartbeat waveform is small, the output is performed with a high gain by the above sensitivity switching.
The control means (50) determines the stress level based on the obtained CVRR value (step 2).

  Next, the stiffness level is measured, but the skin resistance can be measured with one hand, so the auxiliary operation unit (42) is instructed to change (for example, `` Please hold it with one hand '') on the display unit (Step 3).

  For the detection of the stiffness level, the current of the first electrode 62 which is the skin resistance detector 60 is measured (step 4), and the stiffness level is determined by the control means 50 (step 5).

Based on the stress level obtained in step 2 and the stiffness level obtained in step 5, a massage course is selected with reference to the table of FIG. 8 (step 6).
When the massage course is selected, the control means (50) applies massage to the user according to the massage course (step 6).

  According to the above, based on the physical condition (stiffness level) and mental state (stress level) of the user, the optimal massage course for the user is automatically selected, and when there is stress Can relieve stress and, when stress is low and stiff, apply a massage that has a high stiffness-relieving effect, so that effective massage based on both physical and mental conditions can be performed.

  Furthermore, the above-described age may be used as a parameter for selecting a massage course based on the stiffness level and the stress level.

In the measurement of the stiffness level described above, it is desirable to switch the sensitivity of the skin resistance detection unit (60) according to the degree of dryness of the hand.
Specifically, as shown in FIG. 10, when the user has dry skin or the like, the skin is dry even if the skin resistance detection unit (60) is touched, and the skin resistance detection unit (60) There is a possibility that the electric resistance between the first electrode 62 and the skin becomes too large, and the current between the first electrode 62 and the third electrode 80 cannot be measured. To cope with this, it was necessary to set the skin electrical resistance to a standard value by applying handy cream or the like to the hand.

  Therefore, when the contact between the skin resistance detection unit (60) and the finger is detected, a threshold value is set for the resistance value between the skin resistance detection unit (60) and the skin (see FIG. 10). By distinguishing the two types of the user, the type of the skin of the user was determined.

  As shown in FIG. 4, the output from the first electrode (62), which is the skin resistance detector (60), is amplified by the first amplifier (64) (low gain) and transmitted to the control means (50). However, when the contact resistance between the electrodes is measured (step 1 in the flowchart of FIG. 11), if the resistance value is equal to or less than a predetermined threshold value, the skin resistance is measured with the same gain (low gain) as the standard skin ( Step 3). If the contact resistance between the electrodes exceeds a predetermined threshold value, it is determined that the skin is dry and further amplified (high gain) by the second amplifier 66 (FIG. 4) connected in series with the first amplifier 64. (Step 2). Thereby, as shown by the dashed-dotted line A of FIG.

Thus, after switching the gain according to the skin condition of the user, the skin resistance is measured (step 3), the stiffness level is determined (step 4), and the display is displayed. (Step 5).
Next, a massage course (for example, the massage courses 1 to 3) according to the stiffness level is selected (step 6), and a massage is performed (step 7).

  During the massage course, in order to visually recognize the change in the stiffness level of the user, the stiffness level is appropriately determined (step 8) and displayed on the display unit (step 9). ). The stiffness level is determined based on the gain determined in step 1.

  Until the massage course is completed or ended by a timer or the like (step 10), it is desirable to repeat the determination of the stiffness level (step 8) and the display on the display unit (step 9). Thereby, there exists an advantage which can confirm a massage effect sequentially.

  By switching the gain according to the skin condition of the user, the firmness level can be measured accurately. Even in the case of a user with dry skin, the firmness level can be determined without applying handy cream. Can receive.

  In any of the above-described embodiments, when detecting the heartbeat waveform, during the measurement, the measurement can be performed in a resting state by suppressing the swinging, vibration, and movement of the user's upper body as much as possible. Even if the massage is stopped or massaged, it is desirable to use a massage with an airbag to the leg that has a small influence on the measurement or a massage such as stretching the back.
