Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a physical treatment device that simultaneously exerts a thermal effect, a vibration effect, and a magnetic effect.

[Conventional technology and its problems]

Conventional physical therapy devices have been proposed that have a thermal effect by heating the affected area to a preset temperature, devices that use a magnetic field such as a permanent magnet, and devices that utilize vibrations such as a vibrator. It has been recognized that for specific treatments, a physical therapy device that has these three effects at the same time is more effective than a physical therapy device that uses each of these thermal effects, magnetic effects, and vibration effects individually. Now you can
For example, such a treatment device is disclosed in Japanese Utility Model Publication No. 53-52304. In the device disclosed in the publication, a plurality of electromagnets are successively constructed by winding an insulated wire around the outside of a core made of a multilayer ferroelastic magnetic material having a hollow cross-section of a flat ellipse or a flat polygon and covering an electrically insulating material. Then, an AC power source is connected to the conductors that are connected to each other with electric wires, a temperature sensor is attached to the electromagnetic part of the conductor, and the change in electrical resistance is used to control the set temperature using the control section of the main body of the instrument. A normal commercial power supply of 100 V is applied until the set temperature is reached, and when the set temperature is reached, the voltage is stepped down and the temperature is stopped by switching to, for example, a 50 V power supply, and when the temperature drops several degrees below the set temperature, 100 V is applied again to raise the temperature to the set temperature. This allows the desired physical treatment to be performed using the three effects of heat, vibration, and magnetism. Therefore, the heating effect has the set effect, but after reaching the set temperature, the voltage is reduced to about 50V, which is about 1/2 of the commercial power supply, and therefore the temperature of the electromagnet is changed again to 100V. It takes time to cool down the power supply until it reaches the temperature at which it switches to 100V, and even if it is turned on again at 100V, the temperature rises quickly, and the power supply switches to a step-down power supply again, which increases the time it takes to turn on 50V. For this reason, a reduced voltage of 50V is applied until the current is re-energized at 100V, and according to electrical theory, the vibrations and magnetic force generated by the magnetic force are significantly reduced. This reduces the magnetic and vibrational effects other than the thermal effect, resulting in less therapeutic effects for the patient during one treatment period.

[Means for solving problems]

In view of this, the present invention aims to extend the energization time of the 100V power supply, eliminate the known drawbacks, and improve the therapeutic effect.The purpose of this invention is to extend the energization time of the 100V power supply, and to improve the therapeutic effect. Cooling fins bent or curved in the direction of one side are brought into contact with both sides of the core and the cooling fin, which are made by stacking a plurality of flat steel plates without being rolled up to form an electromagnet. A flat steel plate core is held between them, and the space between the core and the cooling fins is used to achieve a cooling effect on the core, and the cooling fins are formed from a non-magnetic metal plate with good thermal conductivity, and One unit of electromagnet is constructed by winding an electric wire coated with insulation around the outer periphery of the cooling fin and around the center of the cooling fin excluding both ends to improve the cooling effect of the cooling fin. By using a plurality of devices, the length of time the commercial power supply is energized is extended, thereby providing a physical therapy device with excellent thermal effects, vibrations, and magnetic effects.

〔Example〕

The present invention will be explained below based on the illustrated embodiments.

Fig. 1 is an external view of one unit of electromagnet, Fig. 2 is a vertical sectional view thereof, and Figs. 3 to 5 show an example in which a plurality of electromagnet units shown in Fig. 1 are arranged and used as an affected area treatment device. Give an example.

In the figure, 1 and 2 are cooling fins, which are formed in the same shape and made of a thin metal plate with good thermal conductivity and non-magnetic material, such as aluminum, aluminum alloy, copper, or copper alloy. used,
When the two cooling fins 1 and 2 are placed opposite each other, both ends of the thin metal plate in the longitudinal direction are bent in the same lateral direction so that appropriate ventilation is generated between the fins to provide a space for cooling. Or make it curve. And these two cooling fins 1,
When the cooling fins 2 are disposed oppositely, the concave portions of the respective fins are disposed so as to face each other, so that the cooling fins have a hollow cross-sectional flat cylindrical shape with a space inside. A core 3 is sandwiched between the opposing cooling fins 1 and 2, and the core 3 is made of a magnetic metal such as a flat steel plate so that its width is equal to the width of the opposing cooling fin and its length is shorter than the fin length. It is constructed by stacking a plurality of pieces cut in half and applying a heat insulating coating 4 to the outer surface of the pieces.

Further, after the rollers 3 are sandwiched between the cooling fins 1 and 2 so as to protrude in the width direction, a coating 5 of a good heat conductive insulating material is applied to the outer peripheral surfaces of the cooling fins 1 and 2. The electric wire 6 with the insulation coating 7 is wound the required number of times (for example, several hundred times).
In this case, the insulated wire 6 is wound around the central portion of the cooling fins 1 and 2, leaving both ends in the longitudinal direction, and the heat generated in the winding when energized is radiated to the outer surface of the fin through this end-wound portion of the wire. This allows air circulation in the internal space of the cooling fin and allows for more rapid cooling to be dissipated to the outside. In addition, since the insulated wires are wound in close contact with the outer peripheral surfaces of the two cooling fins, the heat generated in the wires is directly transmitted to the cooling fins, and the core ends protrude slightly in the width direction of the cooling fins. Therefore, as shown in FIG. 3, a plurality of electromagnets are arranged in parallel, and when alternating current is applied to the electromagnets, the magnetic force generated causes the cores to attract and repel each other and vibrate strongly.

The electromagnets configured as a unit as described above are usually used as a set, and each electromagnet is stored with the positions arranged and fixed in a predetermined shape, as shown in FIGS. 3 and 5, for example. Each electromagnet is placed in a bag 8, and the whole is wrapped with an outer cover 9, and an energizing cord 10 is connected to each electromagnet to supply an alternating current, and a temperature sensor is provided to control the temperature generated in this treatment device. 11 will be provided. An external control circuit (not shown) is connected to this temperature sensor.

[Effect]

Now, when the energizing cord 10 is connected to a commercial power source and energized from a 100V power source, a current of 100V voltage flows through the windings, generating a power line, and each electromagnet generates vibration due to its magnetism and magnetic field lines. At the same time, heating of the windings also generates heat, and humidification and magnetic/vibration treatments are performed. When it is detected by the temperature sensor that the temperature of the heat generated has reached the set temperature, the control circuit reduces the voltage to 40 to 60V and energizes each electromagnet. At this time, the magnetic lines of force are weakened and the magnetic and vibrational effects are reduced, but due to the action of the cooling fins, the thermal energy of the electromagnet is quickly dissipated, and the cooling time is short, resulting in the set temperature drop. As a result, the control circuit will switch to supplying 100V to each electromagnet again. Because the cooling fins have a good cooling effect on each electromagnet, the 100V energization time is more than double that of conventional products, and effective vibration and magnetism can be obtained without reducing the magnetic force too much.

[Effect of idea]

According to the present invention, the core of the electromagnet is sandwiched between cooling fins, and the winding is wound around the outer periphery of the fins, leaving both ends in the longitudinal direction of the fins, which improves the cooling performance of the winding and improves the cooling properties during the treatment period. The 100V energization time is more than double compared to conventional products, and not only the thermal effect but also the magnetic and vibration effects are improved, and it has the advantage of being able to perform effective thermal, magnetic, and vibration treatments in a short time in one device. .
