Description

[Detailed description of the invention] 【Technical field】

The present invention relates to a pine surgery machine that performs pine surgery by pressing treatment elements against a human body.

[Background technology]

In pine surgery machines that perform pine surgery by applying pressure to the human body with a treatment element, maintaining the pressurized state for a while is effective for pine surgery, so conventionally, the pressurized state is There are various products available that allow you to maintain the For example, in the method disclosed in Japanese Utility Model Application Publication No. 57-87740, a pair of eccentric and inclined kneading wheels attached to a rotationally driven drive shaft is used as a treatment element, and the treatment is performed by an eccentric component caused by the rotation of the drive shaft. The change in the amount of protrusion in one direction is used to pressurize the human body, and the point at which the amount of protrusion toward the human body reaches its maximum is detected by the rotation angle of the drive shaft, and the drive is stopped for a while at this point when the amount of protrusion toward the human body reaches its maximum. I'm trying to stop the shaft from rotating. Furthermore, Japanese Patent Application Laid-Open No. 56-20458 discloses a device in which a compression band is used as a treatment element to inflate with air supplied from an air pump and apply pressure to the human body, and the compression band is maintained in an inflated state for a while. has been done. However, in the former case, the maximum amount of protrusion is determined by the eccentricity of the massaging wheel, and the absolute position when the amount of protrusion is maximum, that is, when the pressing force on the human body is maximum, is constant. Therefore, there is a problem in that the stimulation may be too strong or too weak depending on the area to be treated or on the person. Even in the latter case, since the pressurization time by the air pump is constant, the stimulation varies depending on body thickness and individual differences, resulting in inconsistencies such as not being effective or being too harsh. In any of the conventional examples, it was not possible to take advantage of maintaining the pressurized state for a while.

[Purpose of the invention]

The present invention has been made in view of these points, and its purpose is to provide a pine surge machine that performs pine surgery with appropriate strength depending on the user, treatment area, and preference. There is something to do.

[Disclosure of the invention]

Accordingly, the present invention provides a pine surgery machine equipped with a drive unit that presses and drives a treatment element toward a human body, which includes a pressure sensor that detects the load applied to the treatment element, and a control unit that controls the drive unit based on the output of this pressure sensor. The present invention is characterized in that it is equipped with a control circuit, so that the load applied to the treatment element, that is, the force applied by the treatment element to the human body, can be feedback-controlled. In this case, it is not only possible to perform pine surge with a strength according to the user's request, to continue stimulation of the strength desired by the user for a predetermined period of time, but also to adjust the change pattern of the stimulation strength. It becomes possible. The present invention will be described in detail below based on the illustrated embodiment. This pine surge machine performs pine surgery by suppressing the shoulders of a human body from above, and the vIfi: Specifically, as shown in FIG. It is located on the back of the chair. FIG. 6 shows a pair of treatment elements 1.1 and a drive unit that moves both treatment elements 1.1 up and down. The drive unit includes a feed screw 10 whose one end is in contact with a motor M capable of forward and reverse rotation as a power source, an id shaft 11 parallel to the feed screw 10, and a plate 9 that supports the upper and lower ends of both. , 9, a feed nut body 12 that slidably engages with the feed shaft 11 and is screwed onto the feed screw 10, and is rotatably mounted on both sides of the feed nut body 12 with shafts 14. It consists of a pair of movable plates 13, a spring 15 that rotates and urges each movable plate 13 downward, and a hemispherical treatment element 1 is attached to an arm 17 protruding from the tip of each movable plate 13. is attached to. In the figure, reference numeral 18 denotes a stopper for stopping the rotation of the movable plate 13 in the biasing direction by the spring 15 at a predetermined position. In addition, the boots 1731 and 3 held on the plates 9 and 9, respectively,
A bell) 30, which is passed between 1 and 2, is connected to the feed nut body 12, and a slit provided in the bell) 30 is
7 otointerrupter ps for detecting (not shown),
, ps2 are provided. When the feed screw 10 is rotated by the motor M, the feed nut body 12 moves upward or downward depending on the direction of rotation of the feed screw 10. When the body 12 moves downward, the treatment element 1 presses the shoulders of the person sitting on the chair from above.The force that presses the shoulders at this time becomes stronger as the feed nut body 12 is lowered downward. However, no pressure greater than the value set by the spring 15 is applied to the shoulder.The range of vertical movement of the treatment element 1 is monitored by the 7 automatic interrupters PS, PS2. As shown in FIG. 1, the hemispherical treatment element 1 includes a disc-shaped base 20 formed integrally with the arm 17, and a hemispherical rubber base 20 that covers the lower surface of the base 20. A pressure sensor 3 is installed between the elastic body 21 and the bottom surface of the base 20. As shown in FIG. A pressure-sensitive conductive rubber 30 is arranged between electrodes 31 and 32, and has the characteristic shown in the fjSA diagram that the resistance value decreases as the pressure increases. Fig. 1 is a block circuit diagram according to the present invention. In the figure, S indicates both of the above-mentioned 7-way interrupters P S + -P
A vertical position detection circuit constituted by S Inversion switching circuit M that controls
D2, drive circuit MD that controls operation and stop of motor M;
, a comparison/discrimination circuit including a comparator C for comparing the outputs of the strength adjustment switch and the pressure sensor 3, and two timer circuits TC, TC. FIG. 7 shows a concrete circuit. A comparison/discrimination circuit in the control circuit CC is formed by a comparator C, a variable resistor VR serving as a strength adjustment switch is connected to the reference voltage side, and a pressure sensor 3 is connected to the comparison voltage side. The drive circuit MD and the inversion switching circuit MD are each formed by transistors Q, Q2 that are turned on and off by the output of the 7-lip 70-tube FF, FF2, and when the transistor Q is turned on, the motor M is energized, and When the transistor Q2 is turned on, the motor M rotates in a direction to lower the treatment element 1, and when the transistor Q2 is turned off, the motor M rotates in a direction to raise the treatment element 1. Now, when the power switch SW is turned on, the reset circuit RC
The pulses output from the 7 rip 70 FF
,, FF2 are set together, and the motor M starts rotating in the direction of raising the treatment element 1. When the movement of the treatment element 1 reaches the upper limit and the interrupter PS (7r) for upper limit detection in the vertical position detection circuit S is turned on, the transistor Q2 is turned on and the rotation direction of the motor M is reversed. The treatment child 1 begins to descend. If the lower limit detection 7-interceptor PS2 is turned on, the treatment element 1 will, on the contrary, start to rise. When the power switch SW is turned on, the treatment child 1 is already activated.
When is located at the upper limit, the treatment element 1 starts to move downward. When the treatment element 1 comes into contact with the shoulder of a user sitting on a chair as it descends, the pressure sensor 3 receives a load approximately equal to the force with which the treatment element 1 presses the shoulder. As the pressure increases, pressure sensor 3
When the output voltage of the comparator C decreases and becomes lower than the reference voltage Vrcf set by the variable resistor VR, the comparator C sets its output to L level. This output enters the 7-rip 70-rip FF via the inverter (2), NOR (NOR), and AND gate A, and also enters the timer circuit TC.
, the former stops the motor M and the variable resistor V
The action of pressing the shoulder is maintained with the strength set by R. The latter starts the timer circuit TC, which is used to control the motor M.
This is to control the stoppage of NOR at a predetermined time, and when this time period has elapsed, the timer circuit TC starts at the fall of the count-up signal j from the timer circuit TC, and the NOR date NOR, , N0R2 starts the motor M in the direction in which the treatment element 1 rises. When the timer circuit TC2 counts up, the motor M is reversed again by the output of NOR, and the treatment element 1 is lowered. With this descent, the massage element 1 gradually increases the pressure applied to the shoulder, but when a predetermined pressure value is reached, the motor M stops and continues pressing the shoulder at the predetermined pressure value for a while, and then the therapy element 1 1 is increased and the pressing force is decreased, and the above operation is repeated. The 70-chart of the above operation is shown in Fig. f58, the waveform diagram of each point indicated by u-y in Fig. fJS7 is shown in Fig.
Shown in Figure 0. In the figure, T,, T2 are timer circuits TC,,TC
2 shows each time limit. Here, a variable resistor VR which is a strength adjustment switch
If the reference voltage Vref of the comparator C changes, the output value of the pressure sensor 3 at the time when the motor M is stopped and the instantaneous circuit TC is started will be changed. Therefore, the pressing force when pressing the user's shoulder for a while can be adjusted to a desired value by the user using the variable resistor VR. Incidentally, when the timer circuit TC2 reaches the upper limit before counting up, the signal 2 input to the timer circuit TC becomes L level, so that the motor M starts lowering at this point. This means that the rising time of the treatment element 1 is shortened. Further, when the pressure sensor 3 detects a high pressure exceeding a predetermined value even though the treatment element 1 is located at the upper limit of movement, the motor M is stopped by the L level output of NG. By the way, as mentioned above, by making the treatment element 1 rotatable and urging it downward with the springs 15,
Even if an abnormal operation occurs, this not only prevents pressure exceeding the value set by the spring 15 from being applied to the user's eyebrows, but also provides the following effects. That is, the same operation as described above can be obtained even when the treatment element 1 is fixed to the feed nut body 12, but in this case, the pressing force applied by the treatment element 1 to the shoulder is In addition to this, even if the motor M is stopped because the pressure value reaches a predetermined value, the downward movement of the feed nut body 12 does not suddenly stop due to inertia. There is a risk that the pressure that will be removed will become considerably high. For this purpose, as shown in FIG. 11, by biasing the rotatable treatment element 1 with a spring 15, the increase in the pressing force on the eyebrows due to the lowering of the feed nut body 12 is suppressed. It is meant to be gradual. @12 Figure shows a specific circuit of another embodiment. In this case, compared to the above embodiment, a motor M capable of speed control is used, and a speed control circuit SC consisting of a transistor Q and resistors R, R1, and R6 is added to the timer circuit TC. The difference is that the 7-rip, 70-tube FF, AND/D) A, /Agate NOR3, inverter I, etc., which were placed on the input side of the FF are removed. Speed control circuit SC
are connected to each resistor R such that the voltage at its connection to the speed control input of motor M when transistor Q is off is higher than when transistor Q3 is on.
, ,R, ,R, are set (for example, each resistance value is set to 10Ω), so that when the timer circuit TC, is not timing out and the transistor Q, is off, the motor M is operated at high speed. When the timer circuit TC, is running and the transistor Q is on, the motor M is operated at a low speed, and as shown in FIG. 13, the motor M is operated at a relatively high speed.
When the pressure on the eyebrows reaches a predetermined value by lowering, the timer circuit TC lowers the treatment element 1 further at a slow speed during the time limit T, and applies pressure to the shoulders. The pressure is then slowly increased a little further from the predetermined value. When the timer circuit TC counts up, the motor M
increases at a high speed only during the time determined by the timer circuit TC2. Massano performs pine surge, which is similar to shiatsu, by gently pushing and pulling gently. Incidentally, the speed control of motor M is, for example, D.
Of course, this can be done using an A converter, etc., and by setting the pressure force to be detected as multiple values and changing the speed sequentially according to each detection, smoother changes in the pressure force can be obtained. It's okay. Furthermore, timer circuits TC on both the above-mentioned actual flow sides. If the resistors R, , R, connected to TC2 are variable resistors, and each time limit T + -72 can be adjusted by yR, it is possible to adjust the stimulation duration and repetition time in addition to the maximum pressing force. can also be done. 14 and below, the hemispherical elastic body 21 covering the bottom surface of the base 20 in the treatment element 1 is hollow, and there is a space between the pressure sensor 3 arranged on the bottom surface of the base 20 and the inner surface of the elastic body 21. An example is shown below. In this case, until the elastic body 21 is bent and supported by the base 20 via the pressure sensor 3, the elastic force due to the flexural elasticity of the elastic body 21 is exerted, so that the treatment element 1 is When the body starts to hit the body, the stimulation becomes lighter, and the stimulation to the body changes gradually. However, when the elastic body 21 is hollow, as shown in FIG. 15, depending on how it hits the body, the pressure sensor 3
In order to prevent the load from acting properly on the pressure sensor 3, which may lead to a dangerous situation, the pressure transmitting member 25 is attached to the surface facing the inner surface of the elastic body 21 of the pressure sensor 3, as shown in FIG. 16, or vice versa. As shown in FIG. 17, it is preferable to provide ribs 26 on the inner surface of the elastic body 21. Note that it is of course possible to use a strain deso sensor or the like as the pressure sensor 3. In addition, although the above embodiment has been described as having a structure that presses the shoulder from above, it may also have a structure that presses the back of the human body from behind, and further, pressurized air as shown in the conventional example may be used. It may also be possible to use a compression band that inflates. In the latter case, this can be achieved by feedback controlling the air pump and valves using an air pressure sensor.

【Effect of the invention】

As described above, in the present invention, since the force exerted on the human body by the treatment element is feedback-controlled, it is possible to reliably obtain a pine surge of appropriate strength according to the user's preferences and symptoms. Therefore, the action of maintaining the pressed state for a while can be effectively utilized, and an extremely high pine surge effect can be achieved.
