Description

  The present invention relates to an air-type massage machine in which arms and legs are massaged by expansion and contraction of an airbag.

  If the amount of blood that returns to the heart (venous return) decreases, for example, by continuing to sit for a long time without moving the leg too much, the venous pressure increases, causing swelling and pain in the lower leg. In recent years, pulmonary embolism (so-called economy class syndrome), which has been pointed out as a danger when moving over long distances by vehicles, is caused by pressure on the thigh veins while sitting on an airplane or train for a long time. It is a symptom caused by clogging of blood vessels in the lungs caused by blood clots caused by increased blood concentration, and death can occur if treatment is delayed or severe.

  In order to improve such swelling, it is effective to consciously bend and stretch the ankle to increase the amount of venous return due to the muscle pump action or to massage. Therefore, many recent massage machines not only relieve stiff shoulders by massaging the upper body with fir balls, but also massage the arms and legs with airbags, and the muscles are compressed and released by the airbags. By repeating, venous return due to the muscle pump action can be promoted, and swelling and pain can be improved.

By the way, as a device for detecting a blood stasis state that causes such swelling, Patent Document 1 discloses a blood flow value measuring device that measures a blood stasis state based on a blood flow value signal from a blood flow sensor. It is shown. FIG. 10 is a side view of the vehicle seat 100 on which the blood flow value measuring device disclosed in the publication is mounted. In this blood flow value measuring apparatus, blood flow information is acquired from the fingertip 104 of the user 103 by a blood flow sensor 102 provided at the tip of the armrest 101. Specifically, the blood flow sensor 102 includes a light emitting unit that irradiates near infrared rays from the surface of the human skin toward the deep layer portion, and a receiver unit that includes a plurality of light receiving elements that receive near infrared light via the deep layer portion. And measures the ratio of hemoglobin to total hemoglobin in human tissue and measures the blood concentration change from the temporal intensity change of the detected light quantity, and the user is based on this blood flow information It is determined whether 103 is congested.
JP 2002-315728 A

  However, the method of measuring a blood flow value using such a blood flow sensor has a problem that it is easily affected by the contact pressure between the sensor and the measurement site and the environmental temperature, and the measured value at the fingertip is not necessarily reduced. There is a problem that it does not always reflect the blood flow state of the thigh or the whole body. Moreover, since it is necessary to always attach or contact the blood flow sensor to the fingertip while measuring the blood flow value, there is also a problem that it causes annoyance and a sense of restraint.

  An object of the present invention is to provide an air massage machine capable of detecting the swelling state of the arms and legs without knowing the massage machine user and knowing the effect of improving the swelling caused by the massage.

  The air massage machine of the present invention is an air massage machine that massages a treatment site by expansion and contraction of an air bag. The air inflow until the air pressure reaches a predetermined inflating pressure at a predetermined air inflow amount of the air bag. The detection means for detecting the volume of the user's treatment site by the airbag and the history of the detection results by the detection means are stored for each user from the amount or the required time until the predetermined inflation pressure is reached. The history information storage means, and during massage, the history data for the user being treated is read from the history information storage means, and is compared with the detection result by the detection means currently being treated, and the degree of swelling And a display means for displaying a calculation result of the calculation means.

  According to the above configuration, when an air inflow amount from a pump for inflating the airbag is set to a predetermined amount in an air massager that massages arms and legs by inflating and contracting the airbag. The detection means detects the volume of the user's treatment site by the airbag from the inflation pressure of the airbag, the amount of air inflow until the predetermined inflation pressure is reached, or the required time until the predetermined inflation pressure is reached. From the detection result, the calculation means performs the swelling determination. For the determination method, the detection result is stored in the history information storage means for each user, for example, the average value of the detection result at the massage start time at the previous massage, or the same time zone at the previous massage. By comparing the average value of the detection results at the massage start time with the detection results at the current massage start time, the degree of swelling is obtained, or the detection results by the detection means from the massage start time to the present are displayed. This is done by calculating the degree of swelling reduction by comparison. In this way, the state of swelling of the arms and legs can be detected without making the user of the massage machine aware of it.

  Then, by displaying the calculation result by voice or video on the display means, the user can perceive the effect of improving the swelling due to the massage, and can be reflected in the adjustment of the massage intensity or time. A massage machine may perceive the massage effect and automatically adjust the massage intensity and time.

  Here, when the user uses the device for the first time, there is no history information and the swelling cannot be determined. However, when the massage operation is performed, the volume of the treatment site is reduced and the swelling is eliminated. Therefore, when the massage operation is performed for a sufficient time, the decrease in the volume of the treatment site becomes bottomed out, and when such a sample is accumulated in the history information storage means to some extent, as described above, There is no problem even if the minimum value is treated as data with no swelling.

  In addition, the pneumatic massage machine of the present invention further includes a control unit that controls the massage mechanism in response to the calculation result of the calculation unit.

  According to the above configuration, the control means controls the massage mechanism and adjusts the massage intensity, time, etc. at the start of the massage operation or in accordance with the degree of swelling obtained by the calculation means as appropriate during the massage operation. To do.

  Therefore, the massage intensity, time, etc. can be automatically adjusted according to the degree of swelling.

  Furthermore, in the pneumatic massage machine of the present invention, the detection of the inflation pressure of the airbag in the detection means is performed after filtering out the biological signal superimposed on the output of the pressure sensor.

  According to the above-described configuration, the detection means is based on the expansion pressure at the predetermined air inflow amount of the airbag, the air inflow amount until reaching the predetermined expansion pressure, or the required time until the predetermined expansion pressure is reached. In detecting the volume of the user's treatment site by the airbag, it is necessary to detect the inflation pressure. On the other hand, a biological signal based on the user's breathing or heartbeat is superimposed on the output of the pressure sensor that detects the inflation pressure. Therefore, the degree of swelling can be accurately detected by removing this biological signal by filtering.

  In the pneumatic massage machine of the present invention, the history information storage means also stores the time when the massage operation is started when storing the detection result by the detection means, and the calculation means is a user who is performing treatment. The history data close to the current time is read when reading the history data.

  According to said structure, the degree of the swelling which changes with time zones can be compared with the historical data of the same conditions.

  As described above, the air massaging machine of the present invention is an air massaging machine in which arms and legs are massaged by the expansion and contraction of the air bag, and the inflow amount of air from the pump for inflating the air bag From the inflation pressure of the airbag when the air pressure is a predetermined amount, the amount of air inflow until the predetermined inflation pressure is reached, or the time required until the predetermined inflation pressure is reached, the detection means is the user's treatment by the airbag. The volume of the part is detected, and based on the detection result, the calculation means performs the swelling determination and displays the sound or video on the display means.

  Therefore, it is possible to detect the swelling state of the arms and legs without making the massage machine user aware of it, to perceive the swelling improvement effect by the massage, and to reflect it in the adjustment of the massage intensity and time.

[Embodiment 1]
FIG. 1 is a perspective view of a massage machine according to the first embodiment of the present invention. The massage machine main body 1 includes a backrest portion 2 equipped with a massage mechanism including a plurality of treatment elements for performing upper body massage, an arm rest portion 3, and airbags 4a and 4b for performing massage on the lower leg. A leg holder 4 and an operation device 5 for performing the type, strength, position adjustment, etc. of the massage operation are provided.

  As shown in FIG. 2, the airbags 4a and 4b provided in the leg holder 4 are connected to each other via an air supply / exhaust device K, an air hose H, and an air supply / exhaust valve B built in the massage machine body 1. The control unit 11 of the control circuit 10 realized by a microcomputer or the like controls the discharge pressure of the air supply / exhaust device K, the opening degree of the air supply / exhaust valve B, and the like, and controls the supply / exhaust state of the air bags 4a, 4b. By doing this, an air-type massage that repeatedly presses and releases the lower leg muscles is performed. It should be noted that in the present invention, the pressure sensor S faces the inner surface of the air hose H, and the air bag 4a when a certain amount of air flows from the air supply / exhaust device K into the air bags 4a, 4b. , 4b is detected by the pressure sensor S, and the degree of swelling of the user is detected as will be described later.

  For this reason, the output of the pressure sensor S as detection means is input to the control circuit 10 via the amplifier A, A / D converted by an A / D converter (not shown), and then input to the control unit 11. At the same time, after being filtered by the digital filter 12 as described later, it is input to the airbag internal pressure value calculation processing unit 13. Then, the detection result of the pressure sensor S input to the airbag internal pressure value calculation processing unit 13 which is a calculation means is stored for each user in the memory 14 which is a history information storage means. The airbag internal pressure value calculation processing unit 13 determines the degree of swelling from the history data and causes the display unit 15 of the operation device 5 to display the history. The result of the input operation is input from the operating device 5 to the control unit 11, and the control unit 11 is shown in FIG. 2 together with the air supply / exhaust device K and the air supply / exhaust valve B in response to the input operation. There is no control of the massage mechanism with the treatment element.

  FIG. 3 is a front view showing an example of the operation device 5. The operating device 5 includes the power switch 21, the stop switch 22, the course selection switch 23, the various adjustment switches 24, the normal configuration of the operating device of the massage machine such as the display unit 15, and the present invention, as described above. In order to determine the degree of swelling for each person, a user selection switch 25 is also provided.

  Below, with reference to FIG. 4, operation | movement of the massage machine of this invention is demonstrated. The user puts his back on the backrest 2 and sits on the massage machine main body 1 and operates the operation unit 5 to select a desired massage course from the course selection switch 23 and various adjustment switches 24. The operation device 5 is provided with course selection switches 23 for several types of whole body automatic courses for treatment according to a predetermined program, and the various adjustment switches 24 allow manual operation of massage operation according to the user's preference. You can also change it. Here, a case where any one of “whole body automatic course” is selected will be described as an example.

  When the motion is started, first, body sensing for acquiring the user's shoulder position information and the like is performed for more than ten seconds, and then a massage motion is automatically executed based on the predetermined program. First, in step S1, a predetermined amount of air flows into the airbags 4a and 4b from the air supply / exhaust device K described above, and the pressure sensor S facing the air hose H in a state where compression of the lower leg is maintained The internal pressure of each airbag 4a, 4b immediately after the start of the massage operation is measured. At this time, when the user selection switch 25 is operated and the history information of the selected user is registered in the memory 14, the same amount of air as the history information flows into the airbags 4a and 4b. Then, the internal pressure of the airbags 4a and 4b immediately after the start of the massage operation is measured.

  Here, the increase in the volume of the area where swelling occurred is well known from experience, such as feeling more cramped in the evening and at night than in the morning. Since the volume increases in the stage where the swelling has progressed, the internal pressure of the airbags 4a and 4b increases. When the swelling is improved by massage, the volume decreases and the internal pressure of the airbags 4a and 4b decreases. On the other hand, since the thickness of arms and legs varies greatly between individuals, it is desirable to set a predetermined amount of air flowing into the airbags 4a and 4b for each user when detecting the degree of swelling. A selection switch 25 is provided. Further, after the rough adjustment by the user selection switch 25, the control unit 11 causes the level of a biological signal such as respiration and heartbeat (pulse) to be superimposed on the internal pressure signals of the airbags 4a and 4b to a predetermined level. Then, finely adjust the predetermined amount of air.

  That is, if the amount of air flowing into the airbags 4a and 4b is insufficient and the compression of the lower leg is insufficient, the biological signal is less likely to be superimposed on the internal pressure signals of the airbags 4a and 4b. In a place where the amount of air inflow is excessive, the leg artery is blocked by excessive compression by the airbags 4a and 4b, and the amplitude of the superimposed biological signal is reduced or completely lost. Become. Accordingly, the control unit 11 can determine whether the current air inflow amount is appropriate from the amplitude of the biological signal superimposed on the internal pressure signal, and the amplitude value of the biological signal stabilizes a predetermined condition. If the air inflow amount is set and maintained so as to satisfy the requirements, the degree of swelling can be appropriately detected for each user under the same conditions each time.

  Therefore, if the user selection switch 25 is operated in step S2, the process proceeds to step S3, and the control unit 11 determines whether or not a history of an appropriate air inflow amount for the selected user is registered in the memory 14. If it is registered, the process proceeds to step S4 where the airbag internal pressure value calculation processing unit 13 compares the internal pressure of each airbag 4a, 4b measured this time with the history information to determine the current degree of swelling. It is determined and further displayed on the display unit 15 in step S5. If it is determined that the current level of swelling is large, for example, an advice such as “It seems that your legs are swollen. We recommend a massage that focuses on the legs.” .

  After the display, in step S6, the mode changes to the massage content change input acceptance mode for a predetermined period. In step S7, the user refers to the display result from the various adjustment switches 24, for example, leg portions. Change input such as increasing the massage strength of one step or making the leg massage time longer than the standard. In step S8, the operation content is changed and the massage operation is continued.

  On the other hand, when the user selection is not performed in step S2 and when the history of the appropriate air inflow amount for the user selected in step S3 is not registered, the process proceeds to step S9, as described above. An appropriate air inflow amount corresponding to the determined user is stored in the memory 14.

  Here, as described above, when measuring the internal pressure of each airbag 4a, 4b and storing the measurement result in the memory 14, the digital signal is removed in order to remove the influence of the biological signal superimposed on the internal pressure signal. A filter 12 is provided. The digital filter 12 removes the respiratory and pulse frequency components by filtering with a large time constant, thereby accurately detecting the degree of swelling.

  If there is no change input of the massage operation from step S9 and step S6, it is assumed that there is no change in the operation content of the massage course in step S10, and the massage operation is continued by moving to step S8. Thereafter, the internal pressure and history information measured immediately after the start of the operation are set as initial values, and the air massage operation is repeated to repeatedly press and release the muscles by changing the air supply / exhaust state of the airbags 4a and 4b. Then, the internal pressure measurement and the storage of the measurement result in the memory 14 are repeated until it is determined in step S12 that the course has ended.

  For example, after the end of the massage operation for about 15 minutes, the airbag internal pressure value calculation processing unit 13 reads the internal pressure history data stored in the memory 14 and calculates the relative value thereof. In step S13, as shown in FIG. Thus, the degree of swelling from the start to the end of the massage is displayed on the display unit 15 in a graph. Thereby, the user can confirm the swelling improvement effect by massage. Here, a line graph is displayed with the degree of swelling on the vertical axis and the elapsed time on the horizontal axis, and shows how the swelling of the left lower leg is improved as the massage progresses. The results of other parts are displayed by operating a display switching button (not shown). By viewing this display, the user can perceive the effect of improving the swelling caused by the massage, and can reflect the effect on the adjustment of the massage intensity and time. The display is not limited to the video as shown in FIG. 5, but may be performed by audio or a combination of audio and video.

  When the degree of swelling is displayed in a graph in step S13, whether or not to register the internal pressure of each airbag 4a, 4b measured immediately after the start of the massage operation in step S14 as history information is registered. In step S15, registration is performed and the process is terminated. If not registered, the process is terminated directly. For example, if data is registered every time a massage machine is used and the average value is calculated together with the data of the person registered in the past, the history information is the average swelling of the user. It will be possible to grasp how far the current level of swelling is from the average. For this reason, when it is difficult to think that it is a sample of appropriate data, such as when it is standing and is significantly swollen, the effect of the current data on the history can be selected by performing step S14.

  As described above, by detecting the degree of swelling from the internal pressures of the airbags 4a and 4b, the detection can be performed in a relaxed state without making the user conscious, and the blood flow sensor can be used. Such variations in detection results such as environmental temperature and contact pressure with the sensor can be suppressed.

  In addition, the user can objectively grasp the level of swelling before performing full-scale massage, making it possible to select a more effective massage method according to the level of swelling. Become. Furthermore, since the degree of swelling is detected while the massage is in progress, the user can know the massage effect of how the swelling has been improved.

  In addition, since the degree of swelling immediately after the start of the massage operation is detected, it is compared with the history information of the same user, so that it is possible to objectively grasp whether the current degree of swelling is normal. Furthermore, considering that the thickness of the arms and legs varies greatly between individuals, the amount of air flowing into the airbags 4a and 4b is set for each user when detecting the degree of swelling. Therefore, it is possible to detect an appropriate swelling according to each user.

  Furthermore, since the user himself / herself can change the massage operation content manually according to the detection result of swelling, effective massage according to the degree of swelling of the user becomes competent.

  Here, for the massage machine, the state of no swelling cannot be recognized, that is, in FIG. 5, the swelling has been eliminated after a lapse of time, or the swelling has not been eliminated even after the massage operation is finished. It cannot be judged. In particular, when the user uses the device for the first time, there is no history data, which is difficult. However, when the massage operation is performed, the volume of the lower leg part is reduced and the swelling is resolved. Therefore, when the massage operation is performed for a sufficient time, the decrease in the volume of the lower leg part is not reduced as shown in FIG. When such a sample is accumulated in the memory 14 to some extent, the minimum value or the average value in the sample can be regarded as data in a state where there is no depression. When the data is obtained, it is possible to display the actual measured value from the start of the massage operation, such as “Currently, the level of your swelling is expected to be XX%”.

  In addition to the above-described change in the internal pressure of the airbags 4a and 4b, as another method of detecting the degree of swelling, the internal pressure of each airbag 4a and 4b has reached a predetermined pressure value (for example, 50 mmHg). It is also possible to detect the amount of air inflow (or time required). In this case, the detection value immediately after the start of the massage operation is set as an initial value, and thereafter, a change in the degree of swelling can be detected from a change in the air inflow amount (or required time) measured repeatedly and intermittently. The predetermined pressure value is not limited to the exemplified value.

  Further, the shape of the airbags 4a and 4b in the massage machine of the present invention has a shape that covers the entire circumference of the measurement site as shown in FIGS. 1 and 6 from the viewpoint of accurately detecting the volume change. However, it may be one that partially compresses the side or rear of the measurement site. In addition, here, a massage machine that pneumatically massages the lower leg is disclosed, but an airbag may be provided at a position where the thigh contacts or an arm rest, etc. As in the case of the above-described crus, the degree of swelling of the thigh, forearm, upper arm, etc. can be detected. Furthermore, the upper body massage is not limited to a therapeutic element such as a fir tree, and an airbag or a roller may be used.

  Further, the airbag is composed of a plurality of independent air chambers 4a1, 4a2, 4a3; 4b1 as shown in FIG. 7 in addition to the one air chamber such as the airbags 4a and 4b shown in FIG. , 4b2 and 4b3. In this platform, the blood in the veins is transferred to the heart by sequentially controlling the expansion and contraction of the air chambers 4a1, 4a2, 4a3; 4b1, 4b2, 4b3. In addition to being able to perform pneumatic massage that pushes back in the direction of the air, by measuring the internal pressure for each air chamber 4a1, 4a2, 4a3; 4b1, 4b2, 4b3, which part of the lower leg is swelled, It becomes possible to grasp in more detail.

[Embodiment 2]
FIG. 8 is a flowchart for explaining the operation of the massage machine according to the second embodiment of the present invention. The massage machine of the present embodiment can use the configuration of the massage machine shown in FIG. 1 to FIG. This flowchart is similar to the flowchart shown in FIG. 4 described above. Corresponding portions are denoted by the same step numbers and description thereof is omitted. It should be noted that in the present embodiment, in step S14a, it is possible to select whether or not the detection result of the degree of swelling of the user is stored in the memory 14 together with the time at the time of detection. Then, it is memorized in the set.

  In the embodiments described hereinafter including this embodiment, the degree of swelling from the change in the internal pressure of the airbags 4a and 4b when a predetermined amount of air flows into the airbags 4a and 4b is determined. Although the description will be based on the detection method, it is needless to say that other methods as described above may be used.

  Therefore, when the history information for the user selected in step S3 is registered in the memory 14, it is further determined in step S21 whether or not the history information is in the same time period. When there is a belt, the process proceeds to step S4 to determine the current degree of swelling and further displayed on the display unit 15 in step S5a. When the display shows that the current swelling is greater than the degree of swelling in the same time zone measured in the past, for example, “Your legs are swollen more than the usual time zone. It is also possible to display on the display unit 15 advice in consideration of the time zone, such as “We recommend a massage with a focus on the legs.” In addition, the same time zone said here points out within 1 to 2 hours.

  On the other hand, in step S21, if the history information is stored but not in the same time zone, the process proceeds to step S10, and the massage operation is continued in step S8 with no change in course content.

  Thus, the internal pressure of each airbag 4a, 4b detected immediately after the start of the operation of the massage machine is compared with the internal pressure of each airbag 4a, 4b of the same user measured in the same time period in the past. The person can compare the degree of swelling before the massage with the degree of swelling in the same time zone of the sound stage, so it is possible to more objectively grasp the current physical condition, such as more fatigue than usual become.

[Embodiment 3]
FIG. 9 is a flowchart for explaining the operation of the massage machine according to the third embodiment of the present invention. The massage machine of the present embodiment can also use the configuration of the massage machine shown in FIG. 1 to FIG. This flowchart is also similar to the flowchart shown in FIG. 4 described above, and corresponding portions are denoted by the same step numbers and description thereof is omitted. It should be noted that in the present embodiment, the massage machine automatically determines the subsequent massage operation in accordance with the degree of swelling detected immediately after the start of the operation or while the massage is in progress.

  That is, after determining and displaying the current degree of swelling compared with the history information for each user in steps S1 to S5, in step S31, the massage intensity is increased by one step for a portion with a large degree of swelling. Change the massage content automatically, such as setting to. In addition, even if the internal pressure measurement is performed in step S11 while continuing the massage operation in step S8, if the current measurement value is smaller than the previous value in step S32, the current massage operation is performed in step S33. However, if the platform is not reduced, it is regarded that the effect of improving the swelling is insufficient, and in step S34, for example, a massage operation in which the strength, the contraction / expansion period of the airbag, or the like is changed is performed.

  Such a configuration eliminates the need for the user to set the massage operation, so that the operation can be performed more easily and effectively. In addition, if the degree of swelling is not improved even after a predetermined time has elapsed after the massage operation starts, the massage operation content is automatically changed, so effective massage according to the user's condition It becomes possible to do.

  As for detecting the pressure of a living body, for example, in Japanese Patent Application Laid-Open No. 9-201336, when measuring an intraocular pressure from air pressure when the cornea is in a predetermined change state by blowing an air flow on the cornea, A non-contact tonometer is shown in which the measurement accuracy of intraocular pressure is improved by performing multiple measurements. However, in this prior art, the plurality of measurements are for improving the measurement accuracy, not for measuring the history. In addition, it is difficult to imagine an application for measuring the history of intraocular pressure.

  In Japanese Patent No. 3121845, arteriosclerosis and hypertension are detected at an early stage by inflating the blood pressure cuff and measuring the arterial volume from the change in the volume of air exhausted in stages and the pressure change in the blood pressure cuff. A diagnosable peripheral artery monitoring device is shown. Even in this prior art, the history is not measured.
