Description

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

Conventional technologies and their problems Conventional physical therapy devices 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, or devices that use vibrations such as a vibrator is proposed. 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 this publication, a plurality of electromagnets each having a core made of a multilayer ferroelastic magnetic material with a hollow cross-section of a flat ellipse or a flat polygon, covered with an electrical insulating material and wrapped with an insulated wire on the outside are arranged in series. An AC power source is connected to 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 temperature until the set temperature is reached in the control section of the main body of the instrument. commercial power supply
100V is applied, and when the set temperature is reached, the voltage is stepped down and switched to, for example, a 50V power supply to stop the temperature from rising.When the temperature drops several degrees below the set temperature, 100V is applied again to raise the temperature to the set temperature. The desired physical treatment is performed using the three effects of heat, vibration, and magnetism. Therefore, the thermal effect has a set effect, but after reaching the set temperature, about 1/1 of the commercial power supply
In order to reduce the voltage to about 50V and conduct electricity,
It takes time to cool down the electromagnet until it reaches the temperature at which it can be switched to energizing with a voltage of 100V again, and even if it is energized again with 100V, the temperature rises quickly and it switches back to the step-down power supply. Therefore, the 50V energization time becomes longer. 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 results in a reduction in magnetic and vibrational effects other than thermal effects, resulting in less therapeutic effects for the patient during one treatment period.

Solution to the Problem In view of this, the present invention has been developed by stacking cooling fins made of non-magnetic and highly thermally conductive metal thin plates on both sides of a core made of a magnetic thin steel plate with a heat-insulating coating applied to the outer surface. The outer side of the cooling fin is made to protrude from the core, and the outside of the cooling fin is coated with a good thermally conductive insulating material, and the insulated wire is collected a required number of times to form the electromagnet coil, and the cooling fin is made to protrude from this coil. A flat permanent magnet is arranged and fixed between the opposing leaf springs and in parallel with the above-mentioned coil at a required distance, and by passing an alternating current through the coils of the electromagnets, the opposite ends of the plate springs are installed. An electromagnet and a permanent magnet attract and repel each other and vibrate, and when the electromagnet side is applied to the affected area, the thermal effect due to the heat generated by the coil and the vibration and magnetic effect effectively perform physical therapy. Provide utensils.

Embodiments The present invention will be described below based on illustrated embodiments.

Fig. 1 is an external view of one unit of electromagnet, Fig. 2 is a vertical cross-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 thin metal plates with good thermal conductivity and non-magnetic material, such as flat metal plates such as aluminum, aluminum alloy, copper, or copper alloy. When the two cooling fins 1 and 2 are arranged opposite to each other, the core 3 is sandwiched between the two cooling fins 1 and 2. The core 3 is made of a magnetic steel plate and is formed to have a width slightly larger than the width of the cooling fins 1 and 2 and a length shorter than the length of the cooling fins, and a heat insulating coating 4 is applied to the outside of the core 3. Ru.

The outer sides of the cooling fins 1 and 2 are coated 5 with an insulating material having good thermal conductivity, and an electromagnetic coil 6 is formed by winding an insulated wire a required number of times, for example, several hundred times. At this time, the core is slightly protruding from both sides of the cooling fin, and the insulated wire is wound around the outside of the core.

In addition, leaf springs 7 and 8 are provided on one of the cooling fins, for example, the cooling fin 1 shown in the figure, and on both sides of the cooling fin, sandwiching the coil, that is, on the portions projecting from the coil.
This is done by bending a leaf spring into a crank shape, and fixing one end of the leaf spring along the outer surface of the fin with a fastener 9 such as a screw or a stud. This opposing leaf spring 7,
The other end of 8, excluding the part that is locked to the fin, has a required distance 11 from the coil 6, and a plate-shaped permanent magnet 10 is installed between the opposing plate springs 7 and 8. be done. The end of this permanent magnet and the leaf spring 7 or 8 are fixed to each other by a locking device 9 such as a screw or a stud, and are integrated into one body.

In addition, since the insulated wire is wound tightly around the outer peripheral surface of the two cooling fins, the heat generated in the wire is directly transmitted to the cooling fin. Since the cores protrude from each other, a plurality of electromagnets are arranged in parallel as shown in FIG. 3, 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 12, the whole is wrapped with an outer cover 13, and an energizing cord 14 is connected to each electromagnet so as to supply an alternating current to the electromagnet. A temperature sensor 15 is provided.
An external control circuit (not shown) is connected to this temperature sensor.

Function 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 winding, generating lines of magnetic force, and the magnet of this electromagnet and the permanent magnet attract and repel each other. Vibration occurs as a result. Heat is also generated by the heating of the coil, and heating and magnetic/vibration treatments are performed. Then, when it is detected that the heat generation temperature has reached the temperature set by the temperature sensor, the control circuit sends 40~
The voltage is stepped down to 60V and energized. 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 and the set temperature is reached. This allows the control circuit to connect each electromagnet again.
It will be switched to 100V current. This cooling fin has 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 significantly reducing magnetic force.

Effects of the invention According to the invention, the core of the electromagnet is sandwiched between cooling fins, and a coil is formed by winding around the outer circumference of the fins, leaving both ends in the longitudinal direction of the fins, and a permanent magnet plate is provided parallel to this coil. This improves vibration generation due to the attraction and repulsion of both magnets and the cooling properties of the coil, and the 100V energization time during treatment is more than double compared to conventional products, improving not only the heating effect but also the magnetic and vibration effects. It has the advantage of providing effective thermal, magnetic, and vibrational treatments in a short period of time.
