DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a musculosurgery machine that combines an air mat and a musculosurgery device in bed, and performs acupressure on both sides of the spine while lying down.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pine surgery machine that has both a pine surgery function and a bed.

Embodiments of the present invention will be described in detail below with reference to the drawings. In the figure, reference numeral 1 denotes a bed main body, and a bed head wall 5 is erected on one end side of the bed main body 1, that is, on the head side, and a resilient mat 3 made of urethane resin is laid on the entire upper surface. ing. Furthermore, an air mat 2 whose upper surface is formed in a wave shape is laid over the entire upper surface of the mat 3. A hollow space 6 is provided at approximately the center of the bed main body 1 and penetrates through the lower surface of the bed main body 1 at an area where a person's body from the neck to the waist comes into contact when a person sleeps on the bed main body 1. Inside, an acupressure unit 8 is disposed, which includes a large number of acupressure elements 7 that perform acupressure by pressing both sides of the spine of the body. As shown in FIG.
are arranged in parallel in the longitudinal direction, and when the acupressure element 7 moves to the top, it protrudes from the air mat 2 and presses the body by pushing the body, and conversely, when the acupressure element 7 moves to the bottom, the air mat 2 It will be about the same as position 2 and will no longer touch your body. An acupressure element cover 9 made of an air mat is provided between both acupressure element rows in which acupressure elements 7 are arranged side by side.
is provided. 10 is an air pillow. When sleeping soundly, the acupressure element 7 is housed in the air mat 2, and the acupressure element cover 9 and air pillow 10 are inflated with air so that the acupressure element 7 does not come into contact with the body. At the other end of the bed main body 1, that is, on the foot side, a foot raising part 11 is formed, the tip of which is inclined upward together with the air mat 2. A sheet 4 having appropriate air permeability is laid on the upper surface of the air mat 2, and a negative potential electrode plate 12 for applying a negative potential to the feet of the body is provided on the upper surface of the sheet 4 of the leg raising part 11. Further, a removable operation box 13 for operating a power switch and acupressure is arranged in a storage section provided on the front side of the bed head wall 5 of the bed body 1.
A drive section 16 including a motor, a pump 14, a solenoid valve 15, etc. for supplying air and driving the acupressure element 7, and a control section 17 consisting of an electric circuit for controlling these are arranged on the lower surface of the bed main body 1. ing. Hot or cold air is blown between the sheet 4 and the air mat 2 to improve the pine surge effect, and an air outlet 18 for blowing hot or cold air is formed on the head side of the shiatsu part 8. be. 19 is a temperature and humidity detection sensor that detects temperature and humidity, and this temperature and humidity detection sensor 19 is mounted on the air mat 2.
or more installed. This temperature/humidity detection sensor 19 keeps the bed body 1 at an appropriate temperature and humidity so that the patient can sleep comfortably, and by blowing hot air, it provides overheating stimulation to improve the pine surge effect.

The acupressure unit 8 has a configuration as shown in FIGS. 3 and 4. Two acupressure elements 7, 7 are arranged in parallel in the direction of the back muscles as a pair, and one pair of acupressure elements 7, 7 are placed on each side of the spine of the body, forming one block. It has been formed. Therefore, one block is composed of four acupressure elements 7.
The acupressure part 8 is placed in a rectangular box 20 with an opening on the top.
It is constructed by storing a block of acupressure elements 7 so as to be vertically movable. Each block has a partition wall 2 as shown in FIG.
It is divided and arranged in 2. The acupressure element 7 is formed into a rod shape, and its tip is formed to match the shape of a human thumb, so that it resembles acupressure by a human. At the bottom of each block of the box body 20, an air bag 21 that can be inflated and contracted with air is placed, and on top of the air bag 21 is placed a movable plate 23 that can move up and down within the block. The plate 23 and the acupressure element 7 are connected by a rod-shaped joint 24 that is thinner than the acupressure element 7. An upper plate 25 and a lower plate 26 are arranged in parallel near the opening of the block of the box body 20 so that the joint 24 can move up and down without tilting. A thrust bearing 27 is provided in each case so that the joint 24 can move up and down smoothly. Now, as shown in FIG. 4b, when air is supplied from the pump 14 to the air bag 21 through the air pipe 28 led out of the box body 20, the air bag 21 expands and moves the moving plate 23 upward. urge Therefore, the acupressure element 7 also moves upward. That is, the acupressure element 7 applies acupressure to the back of the body. Also, the pump 14 is stopped and the solenoid valve 15 is opened to discharge the air in the air bag 21 to the outside via another air pipe 28, thereby deflating the air bag 21 and moving the acupressure element 7 downward. At this point, the upward movement time of the acupressure element 7 is set at 3 to 7 seconds, the downward movement time is set at 1 to 5 seconds, and the most effective acupressure pattern is to slowly push it up and pull it quickly. On the other hand, it gives the feeling of acupressure being applied by a human, providing comfort and improving the pine surge effect. As mentioned above, the two acupressure elements 7 in the direction of the back muscles are paired and driven at the same time, so that it is possible to respond to variations in the position of the acupuncture points among individual users. They are arranged corresponding to both sides, and seven sets are provided corresponding to the body from the neck to the lower back in the direction of the back, and these seven sets, a total of 14 acupressure elements 7, are arranged at approximately equal intervals. This makes it possible to match the spacing between acupuncture points on the human body. The acupressure part 8 constructed in this way is arranged so as to protrude from both sides of the box body 20, and the protruding pieces 29 are placed on the upper edge of the space 6 of the bed main body 1, and the protruding pieces 29 are attached. It is fixed with a screw or the like through the hole 30. The above 7 sets of acupressure elements 7
You can selectively perform either whole acupressure, which is performed by sequentially moving the acupressure device up and down along the direction of the back muscles of the body, or partial acupressure, which is performed by moving only the acupressure element 7 up and down located at a desired point such as the shoulder or waist. In the case of partial acupressure, the acupressure element 7 at that position is moved up and down at least twice, and the number of times of acupressure can be varied according to preference.
Therefore, you can apply acupressure to your liking depending on each acupressure point. For example, if your shoulders are stiff, you can increase the number of acupressures on only your shoulders. In this way, it is possible to increase the number of times a certain point is applied during partial acupressure, thereby further improving the therapeutic feeling. Furthermore, air mattress 2
air bag 21 that applies pressure and moves the acupressure element 7 up and down
The pressure (finger pressure) is freely variable, and this pressure adjustment is performed by providing hysteresis as described later, so that the air inside the air mat 2 and the air can be adjusted depending on the pulsation of air pressure from the pump 14 or the patient's weight. The pump 14 is prevented from frequently turning on and off due to fluctuations in the air pressure inside the bag 21, and discomfort caused by the on/off sound of the pump 14 is eliminated to allow comfortable pine surgery. In the acupressure cycle for whole acupressure or partial acupressure, the pulse rate is detected by the pulse rate detection sensor 68, which will be described later, and the number is considered to be equal to the respiration rate.
The acupressure motion is performed in a cycle of pulse rate/n (an integer), and breathing and acupressure are synchronized as much as possible to allow for easy pine surgery.

Next, the foot raising part 1 corresponding to the foot part of the bed main body 1
1 will be explained. As shown in FIGS. 7 to 9, a lifting plate 32 is hingedly connected to a lower part of the mat 3 by a hinge part 33, which corresponds to the foot part of the air mat 2. A plurality of air bags 31 (three in this embodiment) are arranged under the lifting plate 32. By supplying air into the air bags 31, the air bags 31 are inflated and the lifting plate 32 is hinged. It is tilted upward using the portion 33 as a fulcrum. The inclination angle α can be varied between 5° and 20° by appropriately adjusting the amount of air supplied to the air bag 31.
By slanting upward, the acupressure device 7 can be easily brought into contact with the lumbar region of the body, thereby improving the pine surge effect and reducing blood congestion in the feet. Further, when it is desired to improve the pine surge effect, the foot raising part 11 is tilted at about 15 degrees and the acupressure element 7 is used for acupressure, and when the foot part of the body is to be relieved of blood congestion, the foot raising part 11 is preferably tilted slightly. Furthermore, since the leg raising part 11 is tilted by inflating a plurality of air bags 31, the time required for tilting is short and efficient. Furthermore, the air mat 2 may be inclined in the same way as the leg raising part 11 on the back muscle part of the bed body 1 on the head side opposite to the foot part. It can be used for watching TV and is suitable for rehabilitation purposes. Furthermore, the effect of pine surge can be increased even if pine surge is performed with the back muscles tilted.

FIG. 5 shows the layout of the air pipe 28.
In Fig. 5a, the air bags 21 ₁ for seven blocks of acupressure elements 7 of the acupressure section 8 are connected to solenoid valves 15 ₁ for supplying and exhausting air, and each one of the blocks of acupressure elements 7 is driven. That air bag 21
₁ ...The corresponding solenoid valve 15 ₁ ... is activated. These electromagnetic valves 15 ₁ ... are controlled by the control unit 17, for example, for total acupressure, partial acupressure, etc. so that they operate separately. Figure 6 shows air supply to the air bag 21,
6a, the supply valve 34 in the solenoid valve 15 is closed and the exhaust valve 35 is opened, so that the pump 1
Air from 4 is not supplied to the air bag 21.
When the solenoid valve 15 shown in FIG. 6b is energized,
Since the exhaust valve 35 in the solenoid valve 15 closes and the supply valve 34 opens, the air from the pump 14 flows into the air bag 21.
supplied to 5b, c and d show piping diagrams of the air pipe 28 to the air bag 31, air mat 2 and air pillow 10 of the leg raising part 11, respectively. Note that 36 is a pressure detection sensor that detects the pressure of the air pipe 28. 14 ₂ , 14 ₃ , 14 ₄ are respective pumps, and 15 b , 15 c , 15 d are solenoid valves provided in each air pipe 28 .

FIG. 10 shows an example of the configuration of the switch group of the operation box 13. A power switch _SW1 is provided at the upper part of the operation box 13, and the power switch SW1 is successively arranged at the lower part as follows. Switch SW ₂ for total acupressure, SW ₃ switch for partial acupressure, SW ₄ switch for restful sleep _{, SW 5 switch for reset, SW 6 switch} for temperature adjustment, SW ₇ switch for humidity adjustment,
A switch SW ₈ for negative potential, a switch SW ₉ for tilting the foot raising portion 11, etc. are provided. In addition, pictures of the body are written to correspond to the partial acupressure, and switches SW ₃₁ to _{SW 37} , numbered "No. 1" to "No. 7", correspond to each block of the acupressure unit 8 to each part of the body. , and an indicator light indicating that the block is activated.
L ₃₁ to L ₃₇ are respectively configured. L ₁ to _{L 9} are indicator lamps corresponding to each switch SW ₁ to _{SW 9} . Here, the switches SW ₁ , SW ₃₁ to SW ₃₇ , SW ₈ , and SW ₉ are lock type, and the other switches SW ₂ , SW ₃ ,
SW ₄ and SW ₅ are push-on return type switches. Turning the switches SW ₆ and SW ₇ clockwise to the maximum turns them off, and turning them counterclockwise increases the temperature and humidity. VR ₁ is an adjustment volume that adjusts the strength of finger pressure, and VR ₂ is a volume that adjusts the strength of air pressure on air mat 2.

Next, the operation will be explained according to the block diagram shown in FIG. Signals for selecting various modes from the operation unit 37 consisting of switches configured on the surface of the operation box 13 are input to the control circuit 38 consisting of a microcomputer, and the control circuit 38 causes each display lamp of the operation box 13 to be displayed. A signal is sent to the display circuit 39 of. First, when the power switch SW ₁ is turned on, the pump 14 and solenoid valve 15 for the air mat 2 are turned on by the mat signal c sent from the control circuit 38, and the pressure of the air mat 2 is detected by the mat pressure detection circuit 40. The pump drive circuit 43 and the electromagnetic valve drive circuit 44 are driven through the amplification circuit 41 and the level discrimination circuit 42 with hysteresis until the pressure is set by the mat pressure adjustment volume _VR2 . When the air pressure of the air mat 2 reaches the set pressure, only the motor is turned off and that pressure is maintained. Next, if the mat pressure becomes lower than the set pressure due to a pressure leak inside the air mat 2, the pump 14 is turned on again to maintain the set pressure. To restart the pump 14 at this time, the instruction input is input from the level discrimination circuit 42 with hysteresis, and even though there is no air leakage, the air pulsates due to the pump 14 being turned on and the air pulsates due to the weight of the body. The disadvantage that the pump 14 is frequently turned on and off is compensated for by a level determination circuit 42, which will be described in detail later. Furthermore, by changing the setting of the volume VR 2, the pressure of the air mat ₂ can be made harder or softer because the set level shown in FIG. 13b changes. If the air mat 2 is to be hardened, the pump 14 is restarted, and if the air mat 2 is to be made soft, the solenoid valve 1 is restarted.
5 is turned off and exhausted to soften it. 12th
The figure shows a specific circuit diagram of the level discrimination circuit 42, and the amplifier circuit 4 is connected to the inverting input terminal of the operational amplifier OP.
1 output is input, and a resistor is connected to the non-inverting input terminal.
Connect the connection point of resistors R ₁ and R ₂ consisting of a series circuit of R ₁ , R ₂ and volume VR ₂ , and connect it from the output terminal of the operational amplifier OP to the non-inverting input terminal via the feedback resistor R ₃ . There is. Now, when a signal as shown in Fig. 13a, which is obtained by converting pressure into an electrical signal, is input to the inverting input terminal x point of the operational amplifier OP, the signal shown in Fig. c.
The signal shown in is output. The levels of points A and B at the y point can be varied by changing the volume VR ₂ at hand, and the air pressure can be adjusted to suit your preference. During the period until time _t1 when the signal at point x does not reach the set level of point A at point y, point z at the output end is at H level, turning on the motor and pressurizing the air mat 2. At time t ₁ , the signal at point x becomes y
When the set level at point A is reached, the output signal at point z becomes L level and the motor stops. At this time, the value of the set level at the y point changes from A to B, and the Z point does not reach the H level until the pressure signal decreases to the set level B. Therefore, even if the air pressure pulsates as shown by the broken line in FIG. There is no need to repeatedly turn on and off. time t ₁
When time t has passed since time _t2 arrives, the input signal at point x reaches the set level at point y, so the output at point z becomes H level, and as mentioned above, the motor is turned on and the air mat 2 is turned on. Apply pressure.
Therefore, even if the pressure drops, the motor remains off during time t. Further, the difference between the set levels A and B, that is, the range C is the range that absorbs pressure variations.

In the case of whole acupressure, when the switch SW ₂ is turned on, the indicator lamp L ₂ lights up, and the indicator lamps L ₃₁ to _{L 37} corresponding to each block of the acupressure section 8 also light up, and the four acupressure elements 7 of the acupressure section 8 turn on. One block consisting of the acupressure element 7 sequentially moves up and down once to perform an acupressure operation using the acupressure element 7. This is because the acupressure signal d from the control circuit 38 is input to the acupressure signal distribution circuit 45, and the signals from this acupressure signal distribution circuit 45 are sequentially
The air is sent to electromagnetic valve drive circuits 46 ₁ to 46 ₇ that supply and exhaust air to and from the air bags 21 in each block. That is, after the solenoid valve drive circuit ₄₆₁ is driven,
The next solenoid valve drive circuit ₄₆₂ is driven. Therefore, acupressure is applied to each block of the acupressure section 8 sequentially. Along with these operations, the acupressure pressure detection circuit 47 detects the air pressure during acupressure based on the signal from the pressure detection sensor 36 sent together with the acupressure signal d of the control circuit 38, and increases the output of this acupressure pressure detection circuit 47. The pressure is input to a level discrimination circuit 49 with hysteresis via a width circuit 48, and drives a pump drive circuit 50 that drives the pump 14 until the pressure reaches the pressure set by the acupressure pressure adjustment volume _VR1 . In this way, the acupressure of the acupressure element 7 is voluminous.
This is done by turning only the pump 14 on and off at the pressure set in _VR1 .

In the case of partial acupressure, switch for partial acupressure.
Turn on SW ₃ , and turn on the desired number of switches SW ₃₁ to _{SW 37} corresponding to each block of the acupressure unit 8, numbered ``No. 1'' to ``No. 7''. In this case, acupressure with the acupressure element 7 is performed continuously for a set number of times (two or more times per block), and then the next block is moved to the next block, where the set number of times is repeated, and then the third block is applied. Repeat the action. Of course, if only one of the switches SW ₃₁ to _{SW 37} from “No. 1” to “No. become. At this time, the number of continuous acupressures set for each block is tailored to the needs of fatigue, for example, it is set to the ratio of shoulders: back of the stomach: waist: = X: Y: Z. In the case of the three areas mentioned above, such as the shoulder, back of the stomach, and lower back, "No. 2", "No. 4", and "No. 7" correspond to each location.
By turning on the switches SW ₃₂ , SW ₃₄ , and SW ₃₇ the required number of times, the above-mentioned points can be continuously pressed with acupressure. In addition, each switch SW ₃₁ from “No. 1” to “No. 7”
~If the SW ₃₇ is made into a dial-type switch with a scale, the user can perform partial acupressure at the above-mentioned distribution rate of the necessary number of acupressures according to his or her needs. A timer circuit 51 that stops operating in 15 minutes, for example, so that it will not cause any harm even if you fall asleep in using it in both total and partial acupressure.
It is equipped with

Next, if you want to sleep soundly by using the bed as a bed without performing acupressure such as whole acupressure or partial acupressure, turn on the sleep switch SW ₄ , the control circuit 38 will send out a pillow signal e, and this signal will be sent to the amplifying circuit. 52 and a pump drive circuit 54 and a solenoid valve drive circuit 55
The air pillow 10 and the acupressure element cover 9 are inflated by turning on the pump ₁₄₄ and the solenoid valve 15d.
Along with this pillow signal e, a leg-up signal f is sent from the control circuit 38 to the amplifying circuit 56.
A pump drive circuit 58 and a solenoid valve drive circuit 5 drive the pump ₁₄₂ and the solenoid valve 15b with the output signal of
Sent to 9th. Accordingly, the air bag 31 of the leg raising part 11 is inflated, and the leg part of the air mat 2 is tilted upward. This state is a state of restful sleep, and the air pressure of the air pillow 10, the acupressure element cover 9, and the air bag 31 of the leg raising part 11 is detected and kept constant by receiving a signal from the pressure detection sensor 36. Detection circuits 53 and 57 are provided. The inclination of the leg raising part 11 is to remove blood from the foot part of the body, and the solenoid valve 15b and the pump ₁₄₂ are both turned off by the operation of the timer circuit 60 in about 1 hour, and the leg raising part 11 is turned off. Return to horizontal. This means that even during a restful night's sleep, there is a lot of activity, such as tossing and turning.
This is so as not to interfere with that. However, if the leg-raising switch SW ₉ , which will be described later, is turned on as necessary, the timer circuit 60 will not operate and the inclination of the leg-raising part 11 can be maintained continuously during a restful sleep. . The three switches SW ₂ , SW ₃ , and SW ₉ for total acupressure, partial acupressure, and leg lift are of a switching type that gives priority to the one instructed later in time, and the switch SW ₅ for reset is It can be canceled by pressing .

Negative potential therapy is an option that can be used during sleep, during acupressure, or alone, and is a “negative potential” switch.
When SW ₈ is turned on, the negative potential signal h is output from the control circuit 38.
is connected to the negative potential circuit 6 via the 30 minute timer circuit 61.
2, a negative potential is applied from this negative potential circuit 62 to the negative potential electrode plate 12 placed near the foot of the sheet 4, and electricity is applied to the foot of the body to perform treatment.

The inclination of the foot raising part 11 of the foot part of the bed body 1 is as follows:
If you turn on the "leg up" switch SW ₉ , the incline will be maintained continuously, and you can also turn on the "sleep" switch SW ₄ .
is interlocked with a timer circuit 60 of a one-hour timer, and a lifting plate 32 with a hinge part 33 is interposed on the lower surface of the air mat 2, and a plurality of small-volume air bags 31 are inflated to raise the foot. 11 air mats 2 are tilted.

When blowing hot air or cold air to the bed body 1, the procedure is as follows. The switches SW ₆ and SW ₇ for adjusting temperature and humidity are of the type consisting of an "off" contact and a volume switch, and can be selectively used while sleeping, during acupressure, or alone. When the temperature adjustment switch SW ₆ is turned on and the volume is rotated, a temperature signal j is sent from the control circuit 38 to the temperature and humidity detection circuit 63, and this temperature and humidity detection circuit 6
3, the air is sent to the motor drive circuit 65 and the heater drive circuit 67 via the amplification circuits 64 and 66, turning on the motor and heater, and sending the air at the set level set by the switch _SW6 . It operates in the same way as above when the humidity adjustment switch SW ₇ is turned on and the volume is rotated and set.
You can also switch both the temperature and humidity using SW ₆ and SW ₇ .
When the sheet 4 is set, air is blown so as to maintain the temperature and humidity conditions specified by one or more temperature and humidity detection sensors 19 arranged on the air mat 2 inside the sheet 4.

The signal from the pulse rate detection sensor 68 is input to the control circuit 38 via the amplification circuit 69, and the signal is processed in the control circuit 38 as described above to determine the cycle of the acupressure operation. It is sent as signal d.
