BEST MODE FOR CARRYING OUT THE INVENTION

[0007] This time, the present inventors have promoted recovery of physical functions (for example, muscle fatigue of the body) even when a pulse magnetic field that is so small that no muscle spasm is observed is given to the muscle. I found out that I can. And I found out that this phenomenon is because ions are generated when an eddy current is generated in the body by applying a pulsed magnetic field, and these ions act on muscles.

In the following, an embodiment of the present invention will be described on the assumption that the inventors of the present application have found the first time in this way.

[0008] FIG. 1 is a diagram illustrating an example of a functional configuration of a treatment device according to the present embodiment. In the following description, the values of current, heavy pressure, and magnetic field indicate peak values.

In FIG. 1, the treatment device 10 includes a high voltage pulse generation circuit 11, magnetic coils 12 and 13, a heater control circuit 14, a heater wire 15, and a control unit 16.

The high voltage noise generation circuit 11 generates a pulse signal and supplies it to the magnetic coils 12 and 13.

The magnetic coils 12 and 13 are the same. Each of the magnetic coils 12 to 14 is configured by winding an electric wire (copper wire) having a diameter of 0.1 [mm] 50 times, for example, and has a size of about 10 [cm], for example.

As shown in FIG. 1, terminals 12 a and 13 a on the winding start side of the magnetic coils 12 and 13 are connected to the pulse generation terminal 11 a of the high voltage pulse generation circuit 11. On the other hand, the end terminals 12b and 13b of the magnetic coils 12 and 13 are connected to the pulse generation terminal l ib of the high voltage pulse generation circuit 11. It has been continued. Thus, the magnetic coils 12 and 13 are connected in parallel.

Note that the magnetic coils 12 and 13 are preferably processed using an insulating material so that dielectric breakdown does not occur due to an applied voltage. For example, the magnetic coils 12 and 13 are configured by passing an electric wire through a tube formed using an insulating material such as Teflon (registered trademark).

The heater control circuit 14 is for supplying AC power to the heater wire 15.

The heater wire 15 generates heat when the AC power supplied from the heater control circuit 14 is applied. The surface of the heater wire 15 is processed using an insulating material. One terminal of the heater wire 15 is connected to the terminal 14a of the heater control circuit 14, and the other terminal of the heater wire 15 is connected to the terminal 14b of the heater control circuit 14.

The control unit 16 includes a microcomputer having, for example, a CPU, a ROM, and a RAM, and the CPU executes the program stored in the ROM using the RAM to control the operation of the pulse generator 11. Is.

[0014] The switch group 17 includes a four-source switch for turning on and off the power supplied to the treatment device 10, and a magnetic field adjustment for the user to adjust the magnitude of the Norse magnetic field generated from the high-voltage pulse generation circuit 11. Switch, potential adjustment switch for adjusting the potential applied to the magnetic coils 12 and 13 from the high voltage pulse generation circuit 11, and heater control circuit 14 The temperature at which the heater wire 15 generates heat based on the generated power And a temperature control switch for the user to adjust.

When the power switch of the treatment device 10 is turned on by the user, power is supplied to the treatment device 10. Then, the control unit 16 controls the high voltage pulse generation circuit 11 so as to generate a pulse signal based on values set by the magnetic field adjustment switch and the potential adjustment switch, and is set by the temperature adjustment switch. The heater control circuit 14 is controlled so as to generate AC power based on the value. As a result, the potential of the value set by the potential adjustment switch is applied to the magnetic coils 12 and 13, and the pulse magnetic field of the value set by the magnetic field adjustment switch is generated from the magnetic coils 12 and 13. Also, the temperature near the heater wire 15 is set by the temperature control switch.

Here, the Norse magnetic field generated by the magnetic coils 12 and 13 of this embodiment is 0.05 [T] or more and 1 [Τ] or less, preferably 0.05 [Τ] or more and 0.2 [Τ] or less. The range is a pulsed magnetic field. Also high The potential applied to the magnetic coils 12 and 13 by the voltage pulse generation circuit 11 is, for example, 300 [V] or more and 3 [kV] or less. Furthermore, the temperature range near the heater wire 15 is, for example, 25 [° C] or more and 55 [° C] or less.

Needless to say, the switch group 17 may be provided with switches other than those described above.

As described above, in the present embodiment, the potential applied to the magnetic coils 12 and 13 is adjusted using the potential adjustment switch, and the temperature near the heater wire 15 is adjusted using the temperature adjustment switch. Thus, it is possible to change the reaction threshold value of the affected part to the pulse magnetic field generated from the magnetic coils 12 and 13. Here, the response sensitivity refers to the sensitivity with which the affected area responds to a pulsed magnetic field. For example, when the temperature or potential applied to the affected area is increased, the affected area is likely to react to the pulse magnetic field (that is, the reaction sensitivity is improved). Therefore, if the temperature or potential applied to the affected area is increased, even if a smaller pulse magnetic field is applied, the effect of applying the pulse magnetic field to the affected area can be obtained.

FIG. 2 is a diagram showing an example of an external configuration of the treatment device 10.

In FIG. 2, the control box 19 accommodates the high voltage pulse generation circuit 11, the heater control circuit 14, and the control unit 16 shown in FIG. In addition, the above-described switch is formed on the surface of the control box 19.

In addition, the magnetic coils 12 and 13 and the heater wire 15 are provided with a predetermined inside of a Teflon (registered trademark) mat 18 so that the magnetic coils 12 and 13 sandwich the meandering portion of the heater wire 15. Fixed in position. The material forming the mat 15 is not limited to Teflon (registered trademark). For example, a mat 15 made of cloth may be used.

Simple fasteners (so-called magic tapes (registered trademarks) 18a and 18b) are attached to the mat 18. For use, for example, as shown in FIG. 3 (a), a mat is placed near the knee of a human foot 31. Wrap 18 so that both ends of mat 18 are fastened with simple fasteners 18a and 18b, and magnetic coils 12 and 13 become cramped according to the shape of human foot 31 near the knee. Fig. 3 (b) is a cross-sectional view seen from the direction AA 'in Fig. 3 (a), and it is preferable that the magnetic coils 12 to 14 have a 30 degree force and a 45 degree degree. However, the angle of the magnetic coils 12 to 14 is not limited to such a range as long as it is given according to the affected area. [0020] (Test results)

The inventors of the present application conducted the following tests in order to evaluate the usefulness of the magnetic coils 12 and 13 of the present embodiment.

The subjects were five healthy adults who had no history of bone strength, joints, and nerves and who had not performed special strength training. The average age of the subjects is 23.6 years. The subject's forearm was also measured.

[0021] In the supine position, the subject held the grip strength meter in a posture that did not place a burden on the arm, and the exercise task was performed using this strength meter. The exercise task was an isometric grasping exercise. The exercise load was 50% of the maximum voluntary contraction (MVC). By maintaining this exercise load for 30 seconds, after giving local muscle fatigue to the forearm, I was allowed to rest for 180 seconds. A test was performed with such exercise load and rest as one set.

[0022] In such a test, after having the exercise load maintained for 30 seconds, resting while applying a pulsed magnetic field (magnetic stimulation) to the subject's forearm using the treatment device 10 of the present embodiment. The difference between the exerted muscle strength and the integrated electromyogram (the value obtained by time-integrating the electromyogram's potential) is different between the case of taking a rest and the case of taking a rest without applying magnetic stimulation. investigated.

[0023] FIG. 4 is a graph showing the relationship between the number of tests (number of sets) composed of the exercise load and rest and the muscular strength of the subject. In Fig. 4, 0 [T] indicates the case where the patient was rested without applying a Norse magnetic field. On the other hand, 0.1 [Τ], 0.5 [Τ], and 1.0 [Τ] are 0.1 [Τ], 0, 5 [Τ], and 1.0 [on the subject's forearm using the treatment device 10 of the present embodiment, respectively. It shows that the pulse magnetic field of [Τ] was applied. In FIG. 4, the average value of the muscular strength exerted by the subject when the exercise load is applied to the subject in each set, and the muscular strength exhibited by the subject when the exercise load is applied to the subject before fatigue are shown. The average value is the standard value. In other words, Fig. 4 shows a value obtained by dividing the average value of the muscular strength in each set by the average value of the muscular strength in the first set.

[0024] As shown in FIG. 4, in the case where a pulse magnetic field is not given to the subject, it is found that as the number of sets increases, the exercise load cannot be maintained, and the muscular strength decreases. The In contrast, when a pulse magnetic field of 1.0 [Τ], 0.5 [Τ], and 0.1 [Τ] is applied to the subject, It can be seen that a decrease in the muscular strength can be suppressed. In this way, it can be seen that even when a Norse magnetic field of 1.0 [T] or less is applied, it is possible to suppress the decrease in muscular strength.

FIG. 5 is a graph showing the relationship between the number of tests (number of sets) consisting of the exercise load and rest and the integrated electromyogram. In FIG. 5, “without magnetic stimulation” indicates a case where the patient is rested without applying a pulsed magnetic field, while “with magnetic stimulation” indicates that the treatment device 10 of the present embodiment is used. It is shown that a pulse magnetic field of 0.1 [Τ] was applied to the subject's forearm. In FIG. 5, as in FIG. 4, the average value of the integrated electromyogram when the exercise load is applied to the subject in each set is the integrated electromyogram when the exercise load is applied to the subject before fatigue. A value obtained by standardizing the average value in the figure is shown. In other words, Fig. 5 shows the value obtained by dividing the average value of the integrated electromyogram in each set by the average value of the integrated electromyogram in the first set.

[0026] As shown in FIG. 5, when the pulse magnetic field is not given to the subject, the integral electromyogram increases rapidly as the number of sets increases, whereas the subject has a pulse of 0.1 [Τ]. It can be seen that application of a magnetic field can suppress the increase in integral electromyogram.

4 and 5, it was confirmed that recovery of muscle fatigue can be promoted even if the magnitude of the pulse current flowing through the magnetic coil is so small that no muscle spasm is observed. The recovery of muscle fatigue is thus promoted because ions generated in the body act on the muscle.

[0027] As described above, in the present embodiment, the treatment device 10 is operated in a state of being attached to the affected part (in the example of Fig. 3, the foot 31), so that the magnetic field, potential, and heat can be given to the affected part. did. In this way, an induced current can flow through the body by applying a pulsed magnetic field to the affected area in addition to electric potential and heat. Therefore, the recovery of the function of the body can be promoted more effectively than the conventional treatment device that has been treated only with the electric potential and the heat. In addition, an induced current can flow through the body even when a nose magnetic field is applied to the affected area while wearing. As a result, it is possible to realize a treatment device that can be treated and used more easily than conventional treatment devices that are treated only with electric potential and heat.

[0028] In addition, since a Norse magnetic field is applied to the affected part while increasing the temperature of the affected part by applying heat to the affected part or applying a potential to the affected part, the reaction threshold of the affected part with respect to the pulsed magnetic field is set. Can be improved. That is, by applying at least one of electric potential and heat to the affected area, the effect of applying the pulse magnetic field to the affected area can be enhanced as compared with the case where the pulse magnetic field is applied alone to the affected area. That is, the treatment device 10 of the present embodiment is

It is possible to promote the recovery of the function of the affected area (for example, muscle fatigue and osteoporosis) by a synergistic effect that cannot be obtained by using a combination of electric potential and heat or using a pulsed magnetic field alone.

[0029] Further, by using the magnetic coils 12 and 13, a pulse magnetic field of 0.05 [T] or more and 1 [Τ] or less, preferably 0.05 [Τ] or more and 0.2 [Τ] or less is generated to improve the function of the body. Since the recovery is promoted, the magnetic coils 12 and 13 can be formed by using thinner wires than the conventional one. Thereby, the magnetic coils 12 and 13 (mat 18) can be deformed relatively freely, and the magnetic coils 12 and 13 can be bent in accordance with the shape of the body during use. Therefore, it is possible to fit the magnetic coils 12 and 13 as much as possible to a curved portion such as a shoulder or knee of the body. Therefore, it is possible to realize the recovery of the function of the body with the magnetic coils 12 and 13 having the simplest possible structure.

In the present embodiment, the magnetic coils 12 and 13 and the heater wire 15 are fixed in the mat 18 so that the meandering portions of the magnetic coils 12 and 13 and the heater wire 15 are arranged in a line. Since the mat 18 is formed into a sheet shape, it is easier to attach to the body than before and the treatment device 10 can be realized. Thereby, the use range of the treatment device 10 can be expanded more than before.

Furthermore, in the present embodiment, a pulse current of 100 [Α] is caused to flow through the magnetic coils 12 and 13, and the current passed through the magnetic coils 12 and 13 is significantly lower than that of the conventional (eg, 3000 [Α]). As a result, restrictions on the place of use and handling methods can be reduced compared to the prior art. Note that the value of the pulse current flowing through the magnetic coils 12 and 13 can be 50 [Α] or more and 300 [Α] or less, preferably 100 [Α] or more and 150 [Α] or less. Further, this pulse current is given to the magnetic coils 12 to 14 for a short time (for example, 100 [s]), and the magnetic coils 12 to 14 do not cause dielectric breakdown due to heat generated from the magnetic coils 12 to 14. As given at intervals.

[0032] Note that, as in the present embodiment, if the magnetic coils 12 and 13 have both a function of generating a high potential and a function of generating a pulse magnetic field, the treatment device 10 can be downsized. Force that can be applied Separately from the magnetic coils 12 and 13, a member that generates a high potential (for example, an electric wire) It may be.

In this embodiment, the magnetic coils 12 and 13 and the heater wire 15 are arranged in a line so that the mat 18 can be easily attached to the affected area. There is no need to align the line 15 with the line 15. For example, the magnetic coils 12 and 13 are arranged in a line in the first mat, and the heater wire 15 is arranged in the second mat so that the first and second mats are bonded together. Oh ,.

In addition, a force that uses the heater wire 15 to apply heat to the affected area does not necessarily require a linear heating element.

Further, in the present embodiment, the number of force magnetic coils using two magnetic coils 12 and 13 may be any number as long as it is one or more.

In the present embodiment, the size of the force magnetic coils 12 and 13 in which the size of the magnetic coils 12 and 13 is set to about 10 [cm] can be adjusted to the place to be used. For example, the size of the magnetic coils 12 to 14 can be about 20 [cm]. The size of the magnetic coils 12 and 13 of the present embodiment can be appropriately determined within the range of 5 [cm] to 15 [cm], preferably 6 [cm] to 12 [cm]. .

Further, in the present embodiment, the force of forming the magnetic coils 12 and 13 using an electric wire having a diameter of 0.1 [mm] The diameter of the electric wire used for the magnetic coils 12 and 13 is 0.05 [ mm] or more and l [mm] or less, preferably 0.1 [mm] or more and 0.5 [mm] or less.

[0036] In the present embodiment, the magnetic coils 12 and 13 are formed using electric wires having a circular cross section. However, it is not always necessary to form the magnetic coils using electric wires having a circular cross section. Absent. For example, the magnetic coil may be formed using a thin plate-shaped electric wire (copper wire).

[0037] For example, as shown in FIG. 6, thin plate-like electric wires (for example, copper wires) 61a to 61n having a width of 20 [mm] and a thickness of 0.1 [mm] are processed into a circular shape, and the circular shape is used as the casing. The magnetic wires may be formed by electrically connecting the plurality of electric wires (copper wires) 61a to 61n so that the directions in the order (directions of the arrows in the figure) are the same. In this case, it is preferable to prevent dielectric breakdown from occurring in the formed magnetic coil by, for example, winding a cloth-like tape formed of an insulating material around the electric wires 61a to 61n. [0038] By doing so, it is possible to increase the current flowing through the magnetic coil as much as possible while reducing the thickness of the mat 18 as much as possible in consideration of the above-described effects. As a result, the range of the pulse magnetic field that also generates the magnetic coil force can be widened, and the dynamic range of the treatment device 10 can be further expanded.

In addition, the width and thickness of the thin plate-like electric wires 61a to 61n are not limited to those described above. For example, the width can be 7.5 [mm] or more and 25 [mm] or less, preferably 10 [mm] or more and 20 [mm] or less. The thickness can be 0.02 [mm] or more and 0.5 [mm] or less, preferably 0.05 [mm] or more and 0.2 [mm] or less.

[0039] Further, in the present embodiment, the force for fastening both ends of the mat 18 with the simple fasteners 18a, 18b is held on the simple fasteners 18a, 18b, and a band is placed around the mat 18 attached to the affected part. The mat 18 can be further prevented from shifting its position.
