Description

Technical Field

[0001] The present invention relates to a pulsed electromagnetic field generating device and a driving method thereof, and more particularly, to an electromagnet device of a pulsed electromagnetic field therapeutic apparatus and a driving method thereof. For example, in various therapeutic devices using pulsed electromagnetic fields, as a magnetic field generating unit which is a core component of treatment, there is provided a magnetic field generating module having inner and outer plates of a ferromagnetic material for maximizing the attractive and repulsive forces between two or more coil electromagnets. Such a magnetic field generating module is reset in a horizontal or vertical space with the central axes aligned, and the magnetic force is transmitted to a long distance with low power through the attractive or repulsive force between the other magnetic field generating modules. Background Art

[0002] As the treatment mechanism of pulsed electro-magnetic field therapy, which is one of non-invasive treatment methods, has been revealed through numerous studies, it is widely applied to many therapeutic devices. As Figure 1 shown in the mechanism described in [reference], when a pulsed electro-magnetic field is generated in a specific low-frequency pulse form and applied to cells, depolarization occurs at specific sites of the cell membrane. As a result, Ca 2+ ions flow into the cell interior and increase nitric oxide (NO) inside the cytoplasm. Due to the increased nitric oxide (NO), cyclic guanosine monophosphate (cGMP) of the nucleus is generated, and thus the cells and tissues are activated.

[0003] That is, through multiple research papers, it has been confirmed that when a microcurrent is generated in cells by pulsed electromagnetic fields, the oxygen and mineral absorption rates of the cells will increase, the toxins inside the cells will decrease, and the metabolism of the cells will be activated. Due to promoting actual bone formation and alleviating clinical effects such as swelling and pain, it is used for many wound and pain treatments.

[0004] However, most current therapeutic devices using pulsed electromagnetic fields use loop-shaped coils to generate electromagnetic fields. Due to the structural difficulty in transmitting magnetic force over a long distance, high power needs to be applied to the coils. As a result, the size of the system increases and it is difficult to carry, thus limiting its application as a personal therapeutic device. As an example, in Figure 2The products of MBST Company described in [document] apply the principle of Helmholtz Coil. When the diameter of the toroidal coil is D, a toroidal coil of the same size needs to be used at D / 2. Therefore, the size of the treatment device will increase. To transmit sufficient magnetic force to the central part of the coil, high power is required, so there is a need for a relatively large-sized control facility for controlling the current. The products of Medtec Company also adopt the toroidal coil form, so the size of the electromagnetic field generation part is relatively large and high-power is required. Due to the planar two-dimensional arrangement form, it is difficult to achieve three-dimensional magnetic force transmission. In addition, the products of SE Therapies Company apply a single electromagnetic field generation module without the interaction between coils. To transmit magnetic force over a long distance, multiple coils are combined into a spiral shape, resulting in an increase in size and a need for high power.

[0005] In addition, as Figure 3 shown, in the existing patented technology, a technique is proposed in which multiple single-coil electromagnet modules are arranged radially to sense the gravitational force with the other electromagnet module on the other side. To sense the gravitational force with the other electromagnet separated by a long distance, a large amount of power needs to be consumed.

[0006] To reiterate the existing technology, due to the adoption of toroidal coils, the size is relatively large, and high power is required for long-distance magnetic force transmission. For this reason, the capacity and size of the control device will increase, making it difficult to realize the application development as a portable personal treatment device. In addition, for a module using a single-coil electromagnet, a relatively large amount of power is required to sense the other electromagnet module located at a long distance, so the control device for controlling it will also increase in size.

[0007] On the other hand, the pulsed electromagnetic field (PEMF) therapy method is a treatment method in which a pulsed electromagnetic field is applied to the affected area to regenerate cells and treat inflammation. Since it was approved by the US Food and Drug Administration in 1979 to treat fractures related to malunion, it has been widely used. Recently, with the implementation of various clinical trials and research, it has been applied to the treatment of various diseases (for example, the treatment uses include muscle pain, osteoporosis, and arthritis, etc.). In addition, the magnetic force is applied to the affected area in a specified pulsed form, usually with an intensity of several mT to several hundred mT and a frequency of less than several hundred Hz.

[0008] The pulsed electromagnetic field generation part applicable to the existing pulsed electromagnetic field treatment device sets the coil in a toroidal shape, so the magnetic force decreases rapidly with distance. To transmit the magnetic force over a long distance, a large amount of power is required. Multiple copper coils are wound and current is applied, and the electromagnetic force F generated here is used. Due to these problems, a relatively high power is required to transmit the magnetic force over a long distance. As a result, the size of the control part increases, and the size of the product also increases accordingly.

[0009] Moreover, the pulsed electromagnetic field generation unit of the existing pulsed electromagnetic field therapy device sets the coil in a circular wire form. Therefore, a magnetic field passing through the central part of the coil is generated. Preferably, there is no problem when the part to be treated is a tissue at a long distance, but when treating a tissue at a short distance such as the skin, it is necessary to limit the magnetic force generation site. For example, when using a corresponding treatment method for the regeneration of facial skin tissue, unnecessary magnetic fields may affect the brain. However, in the prior art, due to the circular wire coil form, there is a problem that the magnetic force generation range cannot be limited.

[0010] The pulsed electromagnetic field changes the magnetic force by changing the voltage applied to the coil. That is, in a state where the resistance of the coil is fixed, the current can be adjusted by adjusting the intensity and frequency of the voltage. Thus, the intensity and frequency of the magnetic field B are also changed, and various waveforms can be induced. Depending on the intensity and waveform of the magnetic field, there are various treatment effects, and clinical trials on this are underway.

[0011] Regarding the paper "Veterinary applications of pulsed electromagnetic field therapy" by James S. Gaynora, Sean Hagbergb, Blake T. Gurfeinc, 2018, which is disclosed as a prior art document, in the case of waveforms, the digital A waveform proposed in the bone growth stimulator has an asymmetric characteristic of having a waveform of 5 ms appearing at intervals of 200 us and 20 us and repeating at intervals of 15 Hz, and transmitting an electric field E of 5 V / m. And in the case of the simulated B waveform, it is used in the proposed device to reduce swelling and pain, and has a characteristic of having a short wave of 2 ms appearing at intervals of 27.12 MHz and repeating at intervals of 2 Hz, and transmitting an electric field E of 10 V / m. As described above, the intensity of the electric field E and the magnetic field B transmitted to a long distance are affected by the waveform of the voltage applied to the coil. As described above, when it is necessary to maximize the treatment effect of transmitting magnetic force to a long distance with low power, the polar direction of the magnetic force should alternate at a specified interval without energy loss. In the existing methods proposed in the paper, the voltage change is continuously applied, so heat is generated in the coil due to the back electromotive force of the coil, and energy consumption occurs. That is, there is a problem of reduced energy efficiency.

[0012] A therapeutic apparatus using pulsed electromagnetic fields may have multiple magnetic field generating units. The circuit structure for generating pulsed electric fields may include: a control unit for controlling the circuit; a magnetic force polarity control unit, such as an H-bridge or a digital-to-analog converter (DAC), etc., for controlling the direction of current; a power supply unit, such as a DC / DC (direct current - direct current converter), a BMS (battery management system), an OP AMP (operational amplifier), etc., for amplifying the consumed power and supplying it to the polarity control unit; and an electromagnetic field generating unit composed of coils for generating power. In the voltage waveform applied to the magnetic field generating unit, the magnetic field generated as described above has a specified frequency. Therefore, in the case of using two or more magnetic field generating units and expecting the effect of overlapping and canceling the generated magnetic forces, a synchronous (Sync) magnetic field generating unit is advantageous.

[0013] In the prior art, a control unit such as a CPU (central processing unit) and a microcomputer (Micom) controls multiple magnetic field generating units. As a result, the magnetic field generating units are not synchronized and there are asynchronous intervals, thus resulting in a problem of reduced overlapping and canceling efficiency between the magnetic field generating units. As an example, when four magnetic force generating units are controlled by one microcomputer, the time difference (asynchronous interval) of magnetic force generation between adjacent magnetic force generating units can be several milliseconds or more.

[0079] The specific structural or functional description of the embodiments of the concept of the present invention disclosed in this specification is only used to illustrate the embodiments based on the concept of the present invention. The embodiments based on the concept of the present invention can be implemented in various forms and are not limited to the embodiments described in this specification.

[0080] The embodiments based on the concept of the present invention can have various changes and can have various forms. Therefore, the embodiments are illustrated in the figures and are described in detail in this specification. However, this does not limit the concept of the present invention to a specific disclosed form, but includes all changes, equivalent technical solutions or alternative technical solutions included within the scope of the inventive concept of the present invention.

[0081] Terms such as first or second can be used for various structural elements, and the structural elements are not limited to these terms. These terms are only used to distinguish two structural elements. For example, without exceeding the scope of the invention claimed based on the concept of the present invention, the first structural element can be named the second structural element, and similarly, the second structural element can also be named the first structural element.

[0082] When referring to one structural element being "connected" or "coupled" to another structural element, it can be directly connected or coupled to the other structural element, or there can be other structural elements in between. On the contrary, when referring to one structural element being "directly connected" or "directly coupled" to another structural element, it should be understood that there are no other structural elements in between. The same interpretation should be made for other expressions describing the relationship between structural elements, that is, "between ~", "right in the middle of ~", or "adjacent to ~" and "directly adjacent to ~", etc.

[0083] The terms used in this specification are only for describing specific embodiments and are not intended to limit the present invention. Unless clearly indicated in the context, singular expressions include plural expressions. In this specification, terms such as "including" or "having" are used to specify the existence of implemented features, numbers, steps, actions, structural elements, components, or combinations thereof, and do not preclude the existence or additional possibilities of one or more other numbers, steps, actions, structural elements, components, or combinations thereof in advance.

[0084] Unless otherwise defined, the meanings of all terms used herein, including technical or scientific terms, are the same as those commonly understood by those of ordinary skill in the technical field to which the present invention pertains. The meanings of terms defined in commonly used dictionaries are the same as those in the context of the relevant technology, and unless clearly defined in this specification, they cannot be construed as ideal or overly formalized meanings.

[0085] In the figures, for clarity of illustration, the thicknesses of layers and regions are enlarged. When a layer is referred to as being "on" another layer or substrate, or a layer is bonded or adhered to another layer or substrate, it may be directly formed on the other layer or substrate, or a third layer may exist therebetween. Throughout the specification, the same reference numerals denote the same structural elements.

[0086] Terms such as upper end, lower end, upper surface, lower surface, front surface, rear surface, or upper part, lower part, etc. are used to distinguish the relative positions of structural elements. For example, for convenience, when the upper side in the figure is named the upper part and the lower side in the figure is named the lower part, in fact, without exceeding the scope of the invention claimed by the present invention, the upper part can be named the lower part and the lower part can be named the upper part. Also, the structural elements in the figures are not drawn to scale. For example, for the purpose of facilitating understanding of the present invention, the dimensions of some structural elements in the figures may be exaggerated compared to other structural elements.

[0087] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0088] As Figure 13 shown, the pulsed electromagnetic field generation unit 200 of the embodiment of the present invention includes part or all of an electromagnet unit 201, an electrode control unit 202, a power control unit 203, and an electromagnet operation switch unit 204.

[0089] Among them, "including a part or all" has no significant difference from the above meaning. When a current is applied, the electromagnet unit 201 generates a magnetic field, and the electrode control unit 202 changes the direction of the current applied to the electromagnet unit 201 to change the magnetic polarity of the electromagnet unit 201, thereby inducing a waveform in an alternating current form. Moreover, the power control unit 203 controls the amount of voltage and current applied to the electromagnet unit 201 to control the magnitude of the electromagnetic force. The electromagnet operation switch unit 204, that is, the trigger switch unit, functions as a switch that can start and stop multiple electromagnet units simultaneously. The micro control unit (MCU) 101 of the control unit 100 controls the on / off time of the electromagnet operation switch unit 204 to achieve the operating hertz (Hz). The electromagnet unit 201 of the embodiment of the present invention may include multiple electromagnet units, and may include a first electromagnet unit 201-1, a second electromagnet unit 201-2, a third electromagnet unit 201-3, and a fourth electromagnet unit 201-4. When applied to the knees of the user, they may be located on the upper, lower, left, and right sides respectively. The pulsed electromagnetic field generating unit 200 is used to activate cells.

[0090] As Figure 4 and Figure 5 shown, in the electromagnet unit 201 of the pulsed electromagnetic field generating unit 200, more than two coil electromagnets 210 are formed, that is, multiple coil electromagnets 210 are formed. Through the repulsive and attractive forces of the coil electromagnets 210, magnetic force can be transmitted to a farther distance. Among them, the farther distance can be a distance greater than a reference value. In this case, the electromagnet unit 201 includes: a cylindrical frame 211, which can wind the coil winding 212 into a specified shape; the coil winding 212, which is made of a conductive material such as copper that generates a magnetic field when a current is applied; a ferromagnetic core 213, which is located at the center of the coil to transmit the magnetic field generated from the coil winding to a specified direction; the coil electromagnet 210, which is connected to both ends of the coil winding 212 and is composed of a sheath insulated cable 214 that applies positive (+) and negative (-) polarity currents; an inner plate 220 of the ferromagnetic material, which faces the direction of the human joint and is used to transmit the magnetic force transmitted from the ferromagnetic core 213 to a farther distance; an outer plate (or another side plate) 221 of the ferromagnetic material, which is formed on the opposite side of the inner plate 220 and connects the cores 213 of the pair of electromagnets formed to increase the magnetic force of the inner plate (or one side plate) 220; and a fixing body 222 such as a screw, which is used to fix the inner plate 220 and the outer plate 221 to the core 213 of the electromagnet unit. Among them, the inner side refers to the part that contacts (or is close to) the skin in the body joint of the user.

[0091] In the electromagnet unit 201, the inner plate 220 connecting the core 213 of the coil electromagnet 210 is formed with a close distance of 1 to 2 mm, and the two plates are separated by a specified distance. The outer plate 221 connecting the core 213 of the coil electromagnet 210 in the electromagnet unit 201 is connected into a single body at the shortest distance without a separated distance. In order to transmit the magnetic force to a long distance and make the magnetic force have the characteristics of a pulse signal, for this purpose, it may include a unit 204 for generating a pulse signal and an electrode control unit 202 for changing the magnetic polarity in the form of an H-bridge. Figure 9 and Figure 10 this is clearly presented in. In Figure 10 in the H-bridge, based on the electromagnet unit, the first to fourth switching devices are configured in the form of an H. Each switching device is composed of a transistor, an FET (field effect transistor), or an NPN (or N-channel) device and a PNP (or P-channel) device. Moreover, Figure 13 the micro control unit 101 of can alternately operate the switching devices in such a form that a low (LOW) signal and a high (HIGH) signal are applied to the first and fourth switching devices, or a low signal and a high signal are applied to the third and second switching devices, so as to generate opposite polarities in the electromagnet unit. That is, it can be seen that the magnetic polarity is changed by the complementary operation of multiple switching devices in the diagonal direction.

[0092] And, in order to transmit the magnetic force to a long distance, the pulse applied to the electromagnet unit 201 can be formed in the form of a carrier wave. More than two electromagnet units 201 applicable to the treatment device can be used. A repulsive force is generated on the inner plate 220 of one electromagnet unit, and a repulsive force with the opposite polarity is generated on the other electromagnet unit, so that the magnetic force can be transmitted to a farther distance. Figure 9 this is clearly presented in. Among them, "the pulse is formed in the form of a carrier wave" means that in Figure 9 and Figure 13 the pulse signal (for example, the operating frequency) with a specified frequency and amplitude is divided, and more precisely, the pulse in the pulse generation interval is divided to generate a new pulse for use. It can be seen that the preset pulse signal is modulated for use to transmit the magnetic force to a long distance and make the light penetrate deep. In the embodiment of the present invention, the generated pulse signal of 20 to 50 Hz can be converted into a signal of about 2 MHz for use.

[0093] Figure 9 is a diagram of the AC signal applied to the coil electromagnet, Figure 10 is the H-bridge circuit logic diagram of the embodiment of the present invention, Figure 11 is the CAE image of the magnetic force transmission generated by the repulsive force of the electromagnetic field generation unit, Figure 12CAE image of magnetic force transmission for gravity generation based on an electromagnetic field generation unit.

[0094] Convert the pulse signal of the control electrode control unit 202 into an AC signal. As Figure 10 shown, preferably, the electrode control unit 202 is composed of an H-bridge circuit logic. Under the control of the microcontroller unit 101, the direction of the current applied to the electromagnet unit 201 will change. Thus, the polarity of the inner plate 220 of the electromagnet unit 201 will also change. The H-bridge circuit can operate in various forms according to the embodiments of the present invention. Therefore, it is not particularly limited to one operating form (e.g., complementary operation).

[0095] The electromagnet unit 201 has various forms of coil electromagnets 210 inside. For example, as Figure 6 and Figure 7 shown, two or more various forms of coil electromagnets 210-1, 210-2 are applied in the electromagnet unit 201. The coil electromagnet 210 is connected to the electrode control unit 202 by a cable 214. The cable winds the coil in the form of a winding 212 multiple times around a non-magnetic cylindrical frame 211 and covers an insulating material such as polyethylene-based PVC (polyvinyl chloride) at the end of the coil. Preferably, the material of the cylindrical frame 211 is a non-magnetic material such as plastic.

[0096] Moreover, a ferromagnetic core 213 is applied at the center of the wound coil to transmit the magnetic field generated from the coil winding (or wound coil) 212 to a specified direction. That is, according to the direction of the current applied to the insulating cables 214 connected to the two ends of the coil winding 212, the magnetic polarities at the two ends of the ferromagnetic core 213 become N-S poles or S-N poles. At the two ends of the ferromagnetic cores 213 of a pair of adjacent coil electromagnets 210, the inner plates (or one side plates) 220 are connected to the human body direction with a slight distance apart by fixing bodies 222-1, 222-2, and the outer plates (or the other side plates) 221 are connected and fixed in the opposite direction of the inner plates by fixing bodies 222-3, 222-4. And, in order to transmit the magnetic force to a farther distance, as Figure 6 shown, a permanent magnet 223 can be applied between the coil electromagnets. As Figure 7 shown, multiple coil electromagnets can be connected and used.

[0097] The object of the present invention is to transmit the magnetic force of the core 213 to the inner plate 221 and the outer plate 222 to transmit the magnetic force to a long distance. Therefore, each plate and the fixing body are made of a ferromagnetic material with a relatively high magnetic permeability. The relative magnetic permeability refers to the magnetization ratio, which is the ratio compared with the magnetic permeability in a vacuum. That is, if this value is several hundred to several thousand, it is called a ferromagnetic material.

[0098] AsFigure 4 As shown, when current with + and - polarities flows through the insulated cable 214-1 of the coil electromagnet 210-1 on the left side of the electromagnet unit 201, and current with - and + polarities flows through the insulated cable 214-2 of the right-side coil electromagnet 201-2, according to Ampere's right-hand rule, the inner plate 220-1 of the left-side coil electromagnet 210-1 induces an N pole, and the inner plate 220-2 of the right-side coil electromagnet 210-2 induces an N pole.

[0099] As described above, as Figure 11 shown by the CAE simulation explanation results, the directions of the magnetic forces applied to the two inner plates are the same. Therefore, a repulsive force is generated between them, and thus the magnetic force can be transmitted over a long distance.

[0100] When current with + and - polarities flows through the insulated cable 214-2 of the right-side coil electromagnet 210-2, the inner plate 220-2 of the right-side coil electromagnet induces an S pole, and an attractive force is generated between the inner plates, resulting in a force that pulls each other. When the attractive force is generated as above, as Figure 12 shown by the CAE simulation explanation results, the core parts 213-1 and 213-2 are connected by the outer plate 221, and thus the magnetic force generated between the inner plates can also reach a long distance.

[0101] The applicable number and position of the electromagnet unit 201 can vary according to the anatomical characteristics of the treatment site and can be changed in various ways. When the embodiment of the present invention is applied to the treatment of knee joint pain, cartilage wear will occur. Therefore, preferably, it is set at the position as Figure 8 shown, so that it can face the articular cartilage of the lower end of the femur and the tibial meniscus cartilage where the container has inflammation.

[0102] When the electromagnet unit 201 is set as above and the magnetic force and polarity of each electromagnet unit 201 are changed, as Figure 8 shown, the magnetic force passes through the joint inflammation site in multiple directions with multiple intensities.

[0103] In particular, when current is applied in a way that generates a repulsive force and the facing electromagnet units 201 generate an attractive force, the magnetic force can reach a farther distance.

[0104] Figure 14 is a perspective view of the electromagnet unit according to another embodiment of the present invention, Figure 15 is a cross-sectional view of the electromagnet unit according to another embodiment of the present invention, Figure 16 is based on Figure 14 and Figure 15 the magnetic force transmission CAE image generated by the repulsive force of the electromagnet unit, Figure 17 is based on Figure 14 and Figure 15The CAE image of magnetic force transmission generated by the gravitational force of the electromagnet unit.

[0105] As Figure 14 and Figure 15 shown, the structure of the electromagnet unit 201' of another embodiment of the present invention is substantially the same as that of the electromagnet unit 201 shown in Figure 4 and Figure 5 shown. However, this can be understood as redrawing the electromagnet unit 201 shown in Figure 4 and Figure 5 in another embodiment of the present invention for the purpose of explaining the operation related to long-distance magnetic force transmission using a pair of electromagnets. Therefore, the content related to the electromagnet unit 201' of another embodiment of the present invention is substantially the same as that of the electromagnet unit 201 shown in Figure 4 and Figure 5 shown, and thus the detailed content will be replaced by the above content.

[0106] Briefly, the electromagnet unit 201' may include: a coil winding 212 that applies a current to generate a magnetic force; a cylindrical frame 211 that can wind the coil winding into a specified shape; a copper coil winding 212 that generates a magnetic field when a current is applied; a ferromagnetic core 213 that is located at the center of the coil to transmit the magnetic field generated from the copper coil winding in a specified direction; a sheath insulated cable 214 that is connected to both ends of the coil winding and applies + and - currents of a DC power supply; a ferromagnetic inner plate 220 that faces the direction of a human joint and transmits the magnetic force transmitted from the ferromagnetic core 213 to a long distance; a ferromagnetic outer plate 221 that is formed on the opposite side of the ferromagnetic inner plate 220 and connects the cores 213 of a pair of coil electromagnets 210 formed in the electromagnet unit 201 to increase the magnetic force of the inner plate; and a fixing body 222 such as a screw for fixing the inner plate and the outer plate to the core 213 of the electromagnet unit.

[0107] As Figure 14 and Figure 15 shown, when a magnetic field is generated in a pair of electromagnet units 201', in the case where a repulsive force is generated between the electromagnets, the magnetic force can be transmitted to a farther distance, and in the case where an attractive force is generated between the electromagnets, the magnetic field range can be constantly controlled. That is, when the direction of the current applied to the coil is controlled to generate a repulsive force between the electromagnets, as Figure 16As shown, the same polarity is generated on the inner side plate 220 and the outer side plate 221, so that the magnetic forces can push each other to achieve long-distance magnetic force transmission. And when the direction of the current applied to the coil is controlled to generate an attractive force between the electromagnets, opposite polarities are generated on the inner side plate 220 and the outer side plate 221, thereby restricting the range of magnetic force generation. The outer side plate does not separate, so the effect of increasing the magnetic force of the inner side plate is caused. Preferably, a pair of electromagnet units 201' are formed in pairs such as 2, 4, 6, etc. to generate attractive and repulsive forces between each other. A pair of inner side plates 220 are separated from each other by a predetermined distance, and the outer side plate 221 connects a pair of core portions 213.

[0108] Thus, it is possible to solve the problem that in the pulsed electromagnetic field generation unit applied to a pulsed electromagnetic field therapy device, the coil is formed in a looped wire shape, so that the magnetic force rapidly decreases according to the distance and a large amount of electric power is required to transmit the magnetic force to a long distance (the electromagnetic force generated by applying current using multiple wound copper coils). And, since the pulsed electromagnetic field generation unit applied to the pulsed electromagnetic field therapy device is in the form of a looped wire coil, the problem of being unable to restrict the magnetic force generation range can be solved. That is, in another embodiment of the present invention, in order to use the attractive and repulsive forces of a pair of electromagnet units 201', the magnetic force can be transmitted to a long distance or restricted within a predetermined range as needed.

[0109] Figure 18 It is a cross-sectional view of a multi-layer printed circuit board pattern type electromagnet unit according to another embodiment of the present invention. Figure 19 It is a diagram showing an independent energization pattern of a multi-layer printed circuit board according to another embodiment of the present invention. Figure 20 It is a diagram showing an integrated energization pattern (always inducing the same polarity) of a multi-layer printed circuit board according to another embodiment of the present invention. Figure 21 It is a diagram showing an integrated energization pattern (always inducing different polarities) of a multi-layer printed circuit board according to another embodiment of the present invention. Figure 22 It is a diagram for explaining the connection of the energization patterns of each layer of a multi-layer printed circuit board according to another embodiment of the present invention.

[0110] For a pulsed electromagnetic field medical device with a relatively thin thickness and a low magnetic force intensity, a small magnetic force generation unit should be provided. For this purpose, in another embodiment of the present invention, when current flows by forming a conductive energization pattern in a spiral curve manner on the inner layer of the multi-layer printed circuit board 310, the function of a small electromagnet unit can be realized. As shown in the pair of electromagnet units 201', when the inner side plate 320 and the outer side plate 321 are adopted, control can be achieved through the attractive and repulsive forces between a pair of magnetic force generation parts.

[0111] As Figure 22As shown, the energized patterns provided within a multilayer printed circuit board can be connected to each other to increase the magnetic force intensity. In the general printed circuit board manufacturing process, the patterns of each layer can be connected through via holes and gold plating processes. Generally, the printed circuit board can increase the number of inner layers in the form of single-sided, double-sided, 4-layer, and 6-layer configurations. As Figure 19 shown, according to the magnetic field polarity and purpose, a pair of energized patterns can be independently formed, or as Figures 20 to 21 shown, they can be connected to each other to be integrated in a closed circuit manner. As Figure 19 shown, in the case of implementing the independent energized pattern method, it has the advantage of being able to control each polarity as needed, but has the disadvantage of an increase in the number of electromagnet units that need to be controlled. As Figures 20 to 21 shown, when adopting the integrated energized pattern, it can have the characteristic of always generating the same polarity or different polarities, but the number of electromagnet units that need to be controlled is reduced, which can reduce the load on the control unit.

[0112] Figure 18 The cross-section of a pair of electromagnet units using a multilayer printed circuit board pattern showing another embodiment of the present invention. The printed circuit board type magnetic force generating unit 301 using a multilayer energized wire may include: an energized pattern line 311 (usually made of copper and in a spiral curve form), formed within the multilayer printed circuit board; a strong magnetic inner plate 320, directly facing the treatment site, for transmitting the magnetic force transmitted from the energized pattern 311 to a long distance; a strong magnetic outer plate 321, formed on the opposite side of the strong magnetic inner plate 320, connecting the magnetic forces generated from a pair of energized wires 311 formed within the printed circuit board type magnetic force generating unit 301 to increase the magnetic force of the inner plate; and a strong magnetic core pin 322, located at the center of the coil in order to transmit the magnetic field generated from the energized pattern 311 to a specified direction. In this case, the inner plate and the outer plate can be connected and fixed through the core pin.

[0113] Figure 23 A schematic diagram of an electromagnet unit using a permanent magnet and a coil, Figure 24 A cross-sectional view of an electromagnet unit applicable to a permanent magnet and a coil.

[0114] For the electromagnet unit 401 using a permanent magnet and a coil, when generating a pulsed electromagnetic field with low power, as Figure 23 shown, a permanent magnet type electromagnet unit 401 can be adopted, which uses a coil 410 for generating an electromagnetic field in a permanent magnet 420. A specified intensity of magnetic force is always generated in the permanent magnet. Regarding this, as described above, an electromagnetic field with an opposite polarity is generated by controlling the voltage. As a result, the magnetic force intensity of the permanent magnet becomes a specified hertz and stimulates the treatment site. As Figure 24As shown, the permanent magnet type electromagnet unit 401 can adopt a cylindrical frame 411 to wind the coil winding 410 into a specified shape. Preferably, the cylindrical frame 411 is made of a non-magnetic material such as plastic. As needed, the cylindrical frame 411 can be made of a ferromagnetic metal material. When a ferromagnetic metal material is used, the strength of the permanent magnet and the magnetic field region can be controlled over a larger range.

[0115] As Figure 24 shown, the permanent magnet type electromagnet unit 401 of another embodiment of the present invention may include: a coil winding 410 that generates a magnetic force according to the application of current; a cylindrical frame 411 that can wind the coil winding into a specified shape; a sheath insulated cable 414 that is connected to both ends of the coil winding and applies + and - currents of a DC power supply; and a permanent magnet 420 that always generates a magnetic force.

[0116] Figure 25 Schematic diagram of a pulsed electromagnetic field generation unit rotated by a permanent magnet. Figure 26 Schematic diagram of applying an enclosure to limit the pulsed electromagnetic field.

[0117] The pulsed electromagnetic field generation unit 501 rotated by a permanent magnet is a unit that uses a motor to rotate the permanent magnet at a specified RPM (rotation speed) in order to generate a pulsed electromagnetic field with low power. Preferably, the rotational RPM of the motor is from several tens to several thousands of RPM, so that the change in the pulsed electromagnetic field reaches several to several tens of Hz. A bracket made of a non-magnetic material such as plastic can be used to connect the permanent magnet and the motor. Different from the rotating permanent magnet, a housing 520 made of a ferromagnetic material can be used, which is fixed to the device and has an opening in a specified direction (treatment site). This is clearly shown in Figure 26 As such, preferably, the magnetic field can be prevented from being transmitted to unnecessary parts. The housing has at least one opening shape 521, and the opening direction coincides with the polarity direction.

[0118] More specifically, as Figure 25 and Figure 26 shown, the pulsed electromagnetic field generation unit 501 rotated by a permanent magnet may include: a permanent magnet 420 that always generates a magnetic force; a motor 510 that rotates the permanent magnet to induce a change in the magnetic force; a tray 511 that fixes the permanent magnet and is connected to the motor; a housing 520 made of a ferromagnetic material that has an opening area in a specified direction and controls the diffusion direction of the pulsed electromagnetic field generated by the rotation of the permanent magnet; and an opening hole 521 that allows the magnetic force to pass through.

[0119] Figure 27 Voltage control waveform diagram of another embodiment of the present invention.

[0120] As described above, the intensity of the electric field E can be changed according to the voltage waveform applied to the electromagnetic field generating device. When continuously changing the waveform of the applied voltage / current in order to alternately change the polarity of the magnetic field at a specified Hz, the energy efficiency is reduced due to the generation of back electromotive force at the inflection point. Therefore, in another embodiment of the present invention, as Figure 27 shown, the polarity of the voltage is changed at a specified period to generate a pulsed electromagnetic field.

[0121] For example, when an N pole is initially (or minimally) generated at the treatment site due to the flow of current, the direction of the voltage is reversed after a specified time to alternately change the polarity of the treatment site to an S pole. As Figure 27 shown, a rest period of several μs to ms can be applied in the voltage change interval to prevent the generation of back electromotive force at the polarity change portion. Also, while alternately changing the direction of the voltage at a specified period, a short-wave burst frequency (e.g., several K to MHz) can be applied in each interval. As shown in the embodiment of the present invention, when changing the direction of the voltage and using the burst frequency in each specified period to generate a pulsed electromagnetic field, long-distance transmission can be achieved with low power.

[0122] Figure 28 A system block diagram for synchronizing the generation of an electromagnet for another embodiment of the present invention, Figure 29 A flowchart showing the process of controlling a trigger switch unit, Figure 30 An H-bridge circuit logic diagram for another embodiment of the present invention.

[0123] As described above, for the synchronization of pulsed electromagnetic fields using a trigger switch, if multiple electromagnet modules are controlled by a single microcomputer (MICOM) (where a module can refer to multiple circuit-integrated IC chips, etc., or can refer to a board formed by a chip and its peripheral circuits on a printed circuit board, and a module can be a component, device, apparatus, etc.), an asynchronous interval will occur for each electromagnet, and the overlapping and cancellation efficiency between the magnetic forces generated by each electromagnet will be reduced. In an embodiment of the present invention, in Figure 29 , a trigger switch unit 6 can be additionally formed between the microcomputer constituting the control unit 1 and the electromagnet polarity control units (2: 2-1, 2-2, 2-3, 2-4).

[0124] The trigger switch unit 6 simultaneously sets the polarities of the polarity control units (2: 2-1 to 2-4) and makes them operate. Thereby, the multiple polarity control units will operate simultaneously, and the magnetic force outputs of the electromagnet units will also be synchronized.

[0125] The steps for controlling the trigger switch unit 6 can be as Figure 29Implementation. In particular, it is possible to consider controlling the trigger switch unit during the rest period of the input voltage described above. More specifically, the trigger switch unit 6 or the step of controlling the pulse electromagnetic field frequency of the trigger switch unit may include the step S1600 of setting the polarity of each electrode control unit (Electrode Control Unit), the step S1610 of turning on (on) simultaneously through the trigger switch unit (Trigger Switch Unit), the step S1620 of turning off (off) simultaneously through the trigger switch unit, the step S1630 of maintaining the off step (rest period), the step S1640 of setting the polarity of each electrode control unit, the step S1650 of turning on simultaneously through the trigger switch unit, the step S1660 of turning off simultaneously through the trigger closing unit, and the step S1670 of maintaining the off step (rest period).

[0126] Figure 30 Represents the logic diagram of the H-bridge circuit, which can be understood as being redrawn for the convenience of explanation Figure 10 . Therefore, Figure 30 The detailed content related to Figure 10 Is replaced by the content described in. Briefly, in the H-bridge, based on the electromagnet unit, the first to fourth switching devices form an H shape. Each switching device is composed of a transistor, FET, or NPN (or N-channel) device and a PNP (or P-channel) device. Moreover, Figure 13 The micro control unit 101 can alternately operate the switching devices in such a form that a low signal and a high signal are applied to the first and fourth switching devices, or a low signal and a high signal are applied to the third and second switching devices, so as to generate opposite polarities in the electromagnet unit. That is, it can be seen that the magnetic polarity is changed by the complementary operation of multiple switching devices in the diagonal direction.

[0127] In addition to the above content, the pulse electromagnetic field generation module (or device, etc.) of the pulse electromagnetic field therapy instrument applicable to another embodiment of the present invention can perform various operations. Other detailed contents have been fully described, so they are replaced by the above content.

[0129] On the other hand, although it is described that all the structural elements constituting the embodiments of the present invention can be combined into one or combined with each other to work, the present invention is not limited to such embodiments. That is, within the scope of the object of the present invention, all the above-mentioned structural elements can also be selectively combined into at least one to work. Moreover, all the structural elements can be respectively implemented as independent hardware, and part or all of each structural element can be selectively combined to be implemented as a computer program with a program module that executes part or all of the functions combined in one or more hardware.

Such a computer program can be stored in a non-transitory computer readable medium and read and run by a computer, thereby implementing the embodiments of the present invention.

[0130] Among them, the non-transitory readable recording medium is not a medium that stores data for a short time such as a register, cache, or memory, but a medium that stores data semi-permanently and can be read by a device. Specifically, the program can be stored in a non-transitory readable recording medium such as a CD (compact disc), DVD (digital versatile disc), hard disk, Blu-ray disc, USB (universal serial bus), memory card, ROM (read-only memory), etc. to be provided.
