Description

Magnetic field generating device for patient treatment {A DEVICE GENERATING MAGNETIC FIELD FOR TREATMENT OF A PATIENT}

The present invention relates generally to devices and methods that use the effects of magnetic and induced electric fields on biological structures.

Known devices are subject to limitations in key parameters that do not allow a satisfactory improvement in visual appearance. Consequently, a new device is needed.

The treatment device generates a time-varying magnetic field for the treatment of cellulite, reducing fat cells and/or increasing muscle volume or strength. Therapeutic devices optimize energy use, increase efficiency, and provide novel treatments. Magnetic impulses can be generated in monophasic, biphasic or polyphasic regimes. The coil is made of individually insulated wire which significantly reduces eddy currents. The coil can be flexibly attached to the casing of the applicator. The coil may be cooled by an air mover on the circumference of the coil. The coil may optionally be a planar coil.

The time-varying magnetic field induces muscle contraction at a higher repetition rate, and the contraction becomes stronger. Treatment can be used to reduce the number and/or volume of fat cells and improve the visual appearance of the treated body region through targeted muscle contraction. In addition, strong muscle contraction at higher repetition rates causes mechanical movement of all layers near the contracted muscle. This method results in remodeling and/or neogenesis of collagen and elastin fibers.

Although the operations of the present invention have been described herein as a series of steps in a specific order, it is understood that the steps of any method of the present invention may alternatively be performed in a different order, unless explicitly stated otherwise. In some embodiments, some or all of the steps may be repeated.

Terms

The biological structure is at least one nerve, neuromuscular plate, muscle fiber, fat cell or tissue, collagen, elastin or skin.

Body regions include muscles or muscle groups, buttocks, saddlebags, love handles, abdomen, hips, thighs, arms, limbs, and/or any other tissue other than the pelvic floor.

A muscle includes at least one of a muscle fiber, a muscle tissue or group, a neuromuscular plate, or a nerve innervating at least one muscle fiber.

Impulse refers to magnetic stimulation, ie the generation/application of a magnetic field. This is the time period when the switch is flipped. The impulse may consist of a single-phase time-varying magnetic field, a biphasic time-varying magnetic field, or a multi-phase time-varying magnetic field sufficient to induce muscle contraction.

Pulse refers to a treatment cycle consisting of one impulse and a time period in which there is no magnetic field generation or is insufficient to induce muscle contraction, i.e., the time period from the rising/falling edge between two impulses to the next rising/falling edge. .

Repetition rate refers to the frequency at which pulses are emitted; It is derived from the time duration of the pulse. This is the same as the frequency at which the switch is switched on.

A hardware panel refers to at least one hardware component used to control a treatment. The hardware panel includes at least one of an operator to control the treatment and an input interface for inputting treatment parameters by the processing unit.

The treatment device may include at least one magnetic field generating device such as a coil. Alternatively, the treatment device may include a plurality of coils. At least one applicator may include at least one coil.

The coil may be constructed of litz-wire, with each wire individually insulated. Each individual conductor is coated with a non-conductive material so that the coil constitutes a number of insulated wires. The insulation of the wire is a significant improvement, as it leads to a significant reduction of induced eddy currents. The small diameter of the wire significantly reduces self-heating of the coil and thus increases the efficiency of the treatment device.

The dynamic forces created by the current pulses passing through the coil's wires cause vibrations and unwanted noise. The wires of the coil may be impregnated under pressure to remove air bubbles between the wires. Spaces between the wires may be filled with suitable materials resulting in integrity, preservation and electrical insulation of the system. Suitable rigid impregnating materials such as resins and resilient materials such as PTE may also be used. Vibration and resonance caused by movement of the individual insulated wires are suppressed by the coil provided as a solid material. Noise is thus reduced.

Coils can be used in hand held applicators; For example, built-in applicators in chairs, beds; or attached to the case of an applicator, for example as a stand-alone applicator on a mechanical fixture. The treatment device may preferably include a human machine interface (HMI) for displaying and/or adjusting treatment parameters. The HMI may include at least one button, knob, slide control, pointer, or keyboard. Alternatively, the HMI may include an audio-visual input/output device such as a touch screen, display unit, input unit, and/or PC including a graphical user interface.

The at least one fastening point secures the connection of the coil to the casing such that the main part of the coil and the main part of the casing of the applicator are spaced apart. In order for air to flow easily, the gap should be at least 0.1 mm. Alternatively, the spacing may be at least 1 mm, most preferably at least 5 mm, to enable cooling medium flow. The gap between the coil and casing can be used for spontaneous or controlled cooling. The coil may be cooled by a fluid, for example air, water or oil. The fastening points can eliminate vibrations of the wire that can be transmitted to the casing of the applicator and thus reduce the noise of the treatment device.

1 is a cross-section of an applicator allowing better flow on the lower and upper sides of the coil and therefore more efficient heat dissipation. The treatment device includes a coil 1, circuit wiring 2 and a fastening point 3 for connecting the coil to the casing of an applicator (not shown). The fastening point 3 is preferably made of a flexible material, but a rigid material can likewise be used. The attachment portion may be provided by a resilient material, such as silicone, gum, or other pliable manner. The fastening point 3 can be located on the outer circumferential side of the coil. However, these fastening points may be located on the lower or upper side of the coil.

Fastening point 3 connects the coil to the case of the applicator at least one point. Alternatively, the coil may be attached to the casing of the applicator via a circular rigid member surrounding the coil. The outer circumference of the circular rigid member may be attached to the casing of the applicator. The coil can be flexibly attached to the inner circumference of the circular rigid member by at least one attachment point. Alternatively the coil may be attached to the circular member by its entire circumference.

The fastening point 3 holds the coil and the main part of the applicator's case apart so that the fluid (which can be air or any liquid) can flow between them. At least one blower 4 may be arranged around the circumference of the coil or perpendicular to the coil. The blower may be any known type of device for introducing a fluid, for example outside air, into the case of the applicator. The blower can be, for example, a fan or a suction pump. In another embodiment, outside air may be cooled before being introduced into the case. The blower may have an inlet disposed around the circumference of the coil to inject air and remove heat from the coil. A connection tube (not shown) may ensure connection of the applicator with the energy source and/or control unit of the treatment device. The connecting tube may also include a conduit for a fluid, for example pressurized air.

Arrow 5 indicates air flow through the applicator. This arrangement of the blower allows air to bypass the coil from the upper and lower (patient's) sides. The outlet may be preferably disposed on the upper side of the casing. The outlet may include a plurality of holes allowing unobstructed removal of the heated cooling medium from the casing of the applicator. By arranging the blower around the circumference of the coil instead of at the top/bottom of the coil, the blower 4 does not interfere with the flux peaks and their lifespan and reliability is increased.

2A is an exemplary embodiment of a casing of an applicator. The schematic includes a casing 6 which may include an outlet 7 arranged preferably on the upper side of the casing 6 . The applicator may further include a handle 8 on the upper side of the casing. The handle 8 can be used for manual placement of the applicator. The connection tube 9 ensures the connection of the applicator with the energy source and/or control unit of the treatment device as well as to the source of fluid. However, the conduits for fluid 10 can also be connected separately.

The connection tube 9 may include a connector for connecting the applicator to the treatment device. The connector can be connected to the connecting tube 9 either at its first end between the connecting tube 9 and the casing 6 or at its second end between the case of the treatment device and the connecting tube 9 . The applicator comprising the coil can be connected to the magnetic therapy device independently on the positioning arm, preferably by means of a connector. The connector may be any kind of electromechanical connector that provides electrical communication of the applicator to the treatment device. Mechanical linkage may be provided by additional latching mechanisms known in the art. The applicator may be replaced by another applicator. Each applicator may include a unique identifier for the applicator for communication with the control unit of the treatment device. Communication may be made through NFC, RFID, ZigBee, IRDC, Bluetooth or wired communication. Alternatively, the applicator may include a mechanical identifier in the pattern, such as a specific combination of a plurality of pins.

2B shows a side view of an exemplary embodiment of a concave applicator. The applicator includes a handling member 8 as a concave portion 11 of the applicator. The recess may allow insertion of a positioning member such as an adjustable length belt. The handling member 8 can also be used for manual positioning of the applicator. The handling member 8 may preferably be at the center of the applicator. The handling member 8 may be on the upper side of the casing 6 of the applicator. The concave portion 11 may have a shape in which one side is open.

2C shows a top view of a concave applicator. The applicator may preferably include a marker 12 over the center of the coil. The marker 12 allows the operator to comfortably position the applicator. The marker may be a recess in the surface of the casing. Alternatively the markers may be different surface covers. Alternatively, the upper side of the casing may include two colors. One color may be on the coil to enable precise positioning of the applicator. The remainder of the applicator may be a different color.

Alternatively, the applicator may be configured to fit a region of the patient's body, including the legs, arms, buttocks or abdomen. The applicator may be shaped to correspond to a region of the patient's body, such as a limb. The shape may include recesses to hold the body region in the correct treatment position. The body area applicator (hereinafter referred to as BR applicator) may have a plurality of sizes configured to fit the patient's body area according to the patient's needs.

The BR applicator may include a first portion on the patient's side, ie the first portion may contact the patient. The BR applicator may include a second portion on the side opposite the first portion, ie the second portion may be farther from the patient than the first portion.

2D and 2E show an exemplary embodiment of a BR applicator 44 used on a limb. The first side portion 45 may be at least partially concave. The first side portion 45 may be V-shaped or preferably U-shaped. The radius of curvature of the first side portion 45 is at least 1 mm, preferably in the range of 10 to 750 mm, more preferably in the range of 50 to 500 mm, most preferably in the range of 60 to 250 mm or up to 1 m. can be The radius of curvature may correspond to the size of the limb. The at least partially concave first side portion 45 may be part of the total curvature of an elliptical or circular shape. The first side portion may be at least a 5° section of the total curvature, which section is preferably in the range of 10 to 270°, more preferably in the range of 30 to 235°, even more preferably in the range of 45 to 180°. range, most preferably in the range of 60 to 135 degrees. The first side portion may be configured to retain the limb within the first side portion during treatment. The first side portion can provide stable equilibrium for the treated body region. Although the limbs may move by muscle contraction, the patient's limbs may remain within the first lateral portion. Lateral movement and/or rotation of the limb may be restricted due to the first lateral portion, and the limb may be in a stable position. Rotational movement relative to the BR applicator can be limited by attaching the BR applicator to a body area.

The second side portion 46 may preferably be on the opposite side of the BR applicator 44 to the first side portion 45 . The second side portion 46 may be substantially planar. The second side portion may be configured to hold the applicator on a patient support on which the patient may lie down during treatment. In an exemplary embodiment, the second side portion may include a positioning mechanism for manually adjusting the position of the coil within the BR applicator.

The BR applicator 44 may be attached to the patient by a positioning mechanism such as an adjustable length belt that may be flexible. In an exemplary embodiment, an adjustable length belt may be secured in a recess/cutout 47 at the first end 48 of the first side portion 45 . The second end 49 of the first side portion 45 may include a recess 50 and a clip mechanism for securing the adjustable length member within the recess 50 . The clip 51 can move around the pin 52 either clockwise or counterclockwise. The clip may be biased by a spring. Alternatively, the clip may be locked by a suitable locking mechanism or by any other method of restraining movement. The clip may include fasteners 53 on the lower side of the clip to secure the correct length of the adjustable member. The fastener may be a hook-and-loop fastener, such as a Velcro fastener, pin type, or the like.

In an alternative embodiment, the BR applicator may include a counterpart to the portion containing the coil. The at least one counterpart may be configured to hold the BR applicator in a static position relative to the body region. The counterpart may preferably be placed on the opposite side of the body region. The counterpart may be attached to the portion comprising the coil by a flexible member or an adjustable-length belt. Alternatively, the counterpart may be attached by a hinge, by a suitable locking mechanism, such as a clip, spring clip, pin type, or the like, or in any other way. The part comprising the counterpart and the coil may preferably at least partially enclose the limb.

The coil may not be planar. The coil can be conical, convex and/or concave, for example biconvex, plano-convex, positive meniscus, negative meniscus, plano-concave or bi-concave. The non-planar shape of the coil may allow for a larger cooling surface and cooling may be more efficient. Also, the non-planar shape can move the peaks of the magnetic field closer to/from the patient, or the profile of the magnetic field can be adjusted by the non-planar shape of the coil. Treatment with non-planar coils can be more efficient than treatment with planar coils. The magnetic flux density generated by the coil sufficient to cause muscle contraction may be low compared to planar coils. Heat dissipation can be enhanced by a larger surface cooled by a cooling medium. Power consumption may be lower.

The applicator may be made of a biocompatible material that allows for high hygiene standards, for example a fluid sterilizable plastic.

A static position of the at least one applicator may be provided by a positioning member. The positioning member can be, for example, an arm or an adjustable flexible belt. The positioning member may ensure intimate attachment of the applicator within proximity of the body region or alternatively direct contact with the patient. Direct contact with the patient may include direct contact with the patient's skin, i.e., contact of the patient's skin with an applicator comprising a coil, or contact of the applicator with the patient's skin through clothing or any remote object. there is. Alternatively, the positioning member may hold the applicator containing the coil out of contact with the patient's skin.

The positioning member may include a buckle for adjusting the length of the belt. The applicator may be placed within a predefined location of the belt. Alternatively, the applicator may be shaped to be movable along the positioning member, for example the shape of the applicator may preferably be concave, eg V-shaped or U-shaped. The positioning member may itself be inserted into the concave portion of the applicator. The position of the applicator can be adjusted by limited movement along the positioning member, since the positioning member can be used as a guide member. However, the applicator may not be fixed in a specific static location. The position of the applicator can be dynamically adjusted during treatment according to the patient's needs. The position of the applicator may be adjusted manually by the operator or automatically by the treatment device. In one exemplary embodiment, multiple applicators may be used to treat larger body regions, such as the buttocks, abdomen or thighs, or pair muscles.

The positioning member may be rigid, and the applicator may be suspended from the positioning member. The positioning arm may include a plurality of movable members, which may be articulated. Motion of the at least one movable member may be translational and/or rotational. The positioning arm may include a joint providing at least one degree of freedom for the at least one positioning arm. In a more preferred embodiment, the positioning arm includes a plurality of degrees of freedom, for example two, three or more degrees of freedom. An example of such a positioning arm may be an open kinematic chain comprising at least two, more preferably four, even more preferably six degrees of freedom. The fixed frame of the open kinematic chain may be the body of the treatment device. The endpoints of the kinematic chain can be applicators and/or coils.

3A shows an exemplary embodiment of a treatment device 13 comprising a positioning arm 14 for positioning an applicator (not shown). The treatment device 13 may include a wheel 15 for moving the treatment device. The wheel can be propelled. A plurality of wheels may preferably be outside the bottom projection of the body of the treatment device to provide enhanced stability of the treatment device.

Figure 3b shows a positioning arm 14 comprising a movable link 16 connected by a joint 17 allowing two, four and most preferably six degrees of freedom. Three of these joints may be locked by a locking mechanism such as a screw mechanism. The positioning arm may include a support member for attaching the connecting tube to the positioning arm. The support member may hold the connecting tube in a direction parallel to the positioning arm.

A positioning arm 14 is attached to a treatment device 13 (not shown) at a first end of the positioning arm 18 . In an exemplary embodiment, the positioning arm is attached to the circumferential side of the case of the treatment device. The positioning arm further comprises a hollow sleeve 19 at the second end 20 . The sleeve 18 includes a gap 21 for removably attaching the applicator 6 to the positioning arm 14 .

The positioning arm may include a member 43 for guiding the connecting tube.

3c shows an applicator 6 that can be removably attached to the positioning arm 14 . Connection of the applicator 6 to the positioning arm is made possible by a locking mechanism. The applicator 6 includes a latching member 22 that is biased by an elastic member. The latching member 22 is configured to fit into the gap 20 in the hollow sleeve 18 at the second end of the positioning arm. Applicator 6 is attached to positioning arm 12 by inserting applicator 6 into sleeve 18 and locking latching member 22 in gap 20 . The applicator may be removed by pressing the latching member and pulling the applicator from the sleeve.

4A and 4B show an exemplary embodiment of a circuit for providing high power pulses to a coil. The proposed circuit involves charging an energy storage device, e.g., a capacitor, from an energy source, repeatedly switching a switching device, e.g., a switch, and discharging the capacitor with a coil to generate a time-varying magnetic field. . Either the energy source or the switch, or alternatively both the energy source and the switch, may be regulated by the control unit 42 . The control unit 42 may adjust and/or enable adjustment of the parameters described herein to generate a time-varying magnetic field for treatment. The control unit 42 can disable generation of the magnetic field by the coil. Adjustment can be done by a pre-established protocol via the HMI or by the operator/end user of the device.

Referring to FIG. 4A , a circuit for providing high power pulses to a treatment device includes a series connection to a switch 23 and a coil 24 . Switch 23 and coil 24 are connected together in parallel with capacitor 25. Capacitor 25 is charged by energy source 26, and capacitor 25 is then discharged through switch 23 to coil 24.

During the second half cycle of the LC resonance, the polarity on capacitor 25 is reversed compared to energy source 26 . In this second half cycle, there is a conflict between the energy source 26 where the voltage on its positive and negative terminals is typically several thousand volts. Capacitor 25 is also charged with positive and negative voltages, typically thousands of volts. As a result, there is twice the voltage of the energy source 26 in the circuit. Thus, the energy source 26 and all connected parts within the circuit are designed for high voltage loads. Therefore, a protection resistor and/or protection circuit 27 must be placed between the energy source 26 and the capacitor 25.

4B shows circuitry for providing high power pulses for improved functioning of the treatment device. Coil 28 and capacitor 29 are connected in series and placed in parallel to switch 30. Capacitor 29 is charged through coil 28. A controlled shorting of the energy source 31 takes place via the switch 30 to provide the energy pulse. In this way, high voltage loading at the terminals of the energy source 31 during the second half-cycle of the LC resonance associated with known devices is avoided. The voltage on the terminals of the energy source 31 during the second half cycle of the LC resonance is the same voltage as the voltage drop on the switch 30 .

The capacitance of the capacitor is in the range of 5 nF to 100 mF, preferably in the range of 25 nF to 50 mF, more preferably in the range of 100 nF to 10 mF, even more preferably in the range of 1 μF to 1 mF, and most preferably in the range of 5 to 10 mF. It may be in the range of 500 μF.

The capacitor may be charged to a voltage of at least 100, 250, 500, 1000, 1500, 2500 V or more.

The capacitor can provide a current pulse discharge of at least 100, 250, 500, 750, 1000, 1500, 2000 A or more. The current may correspond to the value of the peak magnetic flux density of the magnetic field generated by the coil.

Switch 30 may be any kind of switch such as a diode, MOSFET, JFET, IGBT, BJT, thyristor or combination thereof. Depending on the type of component, the load on the energy source 31 is reduced to a few volts, for example 1-10 volts. As a result, there is no need to protect the energy source 31 from high voltage loads, for example thousands of volts. The use of protection resistors and/or protection circuitry is reduced or eliminated. This design simplifies the circuitry used, increases the efficiency of energy use, and provides higher safety.

The inductance of the coil is up to 1 H, or in the range of 1 nH to 500 mH, or in the range of 1 nH to 50 mH, preferably in the range of 50 nH to 10 mH, more preferably in the range of 500 nH to 1 mH, most preferably may range from 1 to 500 μH.

The dimensions of r and R can be used to achieve a convenient shape of the generated magnetic field.

The total coil surface is up to 8000 cm ² , or in the range of 5 to 8000 cm ² , preferably in the range of 10 to 2000 cm ² , more preferably in the range of 20 to 1000 cm ² , most preferably in the range of 50 to 500 cm ² range can be

The core area A1 may range from 0.01% to 99% of the total coil surface. Alternatively, the core area (A1) is in the range of 0.05% to 95%, preferably in the range of 0.5 to 90%, more preferably in the range of 1 to 75%, more preferably in the range of 5% to 60% of the total coil surface, Most preferably it may be in the range of 10% to 40%.

The total weight of the coil may range from 1 gram to 50 kg. The total weight of the coil is preferably in the range of 10 grams to 25 kg, more preferably in the range of 0.1 to 15 kg, even more preferably in the range of 0.5 to 10 kg, most preferably in the kilogram level, for example, It may be 1 kg, 2 kg, 3 kg, 5 kg or more.

Winding magnetic fluence is defined by Equation 2.

where WMF is the winding magnetic fluence [T·cm ² ]; B _PP is the maximum peak-to-peak magnetic flux density generated by coil [T]; A ₂ is the winding area of the coil [cm ² ].

The coil has at least 5, 10, 15 or 20 T cm ² , or in the range of 5 to 40000 T cm ² or in the range of 40 to 40 000 T cm ² , or in the range of 40 to 20 000 T cm ² , preferably is in the range of 50 to 10000 T cm ² or in the range of 75 to 7500 T cm ² , more preferably in the range of 100 to 5000 T cm ² or in the range of 150 to 2750 T cm ² , even more preferably in the range of 200 to 2750 T cm 2 .

According to some embodiments, the coil may have a round, circular, elliptical, square, rectangular or any other shape. Alternatively, the coil may be a solenoid.

6 shows the exponential voltage drop in a capacitor. Energy savings during treatment may be characterized by a reduced voltage drop in the capacitor between the first, second and subsequent resonant oscillation maxima. The magnitude of individual voltage oscillations decays exponentially until energy balance is established. This makes it possible to increase the maximum possible frequency/repetition rate of the magnetic pulse since the frequency/repetition rate depends on the rate at which the capacitor can be recharged. Because the capacitor is recharged by the amount of energy lost during the previous pulse, it is possible to increase the frequency/repetition rate of the therapy device up to hundreds of magnetic pulses per second without the need to increase the input power. The voltage drop between any successive amplitudes is not higher than 45, 40, 30, 21, 14 or 7%.

The treatment device may include at least one sensor for measuring an operating parameter such as voltage, current or phase. A control unit of the treatment device may evaluate one or more signals from the sensors. The control unit may start and/or stop treatment in response to signal values from the sensors.

The burst time (T ₃ ) is equal to T ₁ + T ₂ . T ₂ may last for a period of at least one magnetic pulse in the train. A train contains a plurality of pulses, ie at least two pulses. Bursts can be repeatedly applied to the patient. The burst repetition rate may be in the range of 100 Hz to 0.01 Hz, more preferably in the range of 50 Hz to 0.02 Hz or most preferably in the range of 10 Hz to 0.05 Hz.

Alternatively, at least one capacitor may provide energy to the plurality of coils. Alternatively, both circuits may include a common power supply.

Circuit 32 can generate a time-varying magnetic field independently of circuit 37 . While the second circuit is turned off, the treatment device may generate a magnetic field by one circuit, that is, circuit 32 may generate a magnetic field while circuit 37 is turned off, or circuit 32 may generate a magnetic field while circuit 37 is turned off. Circuit 37 may generate a magnetic field while is turned off.

The control unit makes it possible to assemble the magnetic pulses into various shapes (eg triangular, rectangular, trapezoidal, exponential). The impulse frequency of the impulse may range from hundreds of Hz to hundreds of kHz, more preferably from a few kHz to tens of kHz, and most preferably up to 10 kHz.

The impulse duration may range from 3 μs to 10 ms or more, or alternatively from 3 μs to 3 ms or alternatively from 3 μs to 1 ms. The impulse duration may be less than 3, 10, 50, 200, 300, 400, 500, 625, 1000, 2000 or 3000 μs, for example. Alternatively, the impulse duration may be in the range of ms. The total power consumption may be less than 1.3 kW, for example at least 150, 250 or 500 W, to generate a magnetic flux density sufficient to induce at least muscle contraction. The energy conversion efficiency may be at least 10, 25, 50, 80% or more.

The derivative of magnetic flux density is defined by Equation 3.

where dB is the magnetic flux density derivative [T]; dt is the time derivative [s]. The maximum value of the flux density derivative is at most 5 MT/s, preferably 0.3 to 800 kT/s, 0.5 to 400 kT/s, 1 to 300 kT/s, 1.5 to 250 kT/s, 2 to 200 kT/s , 2.5 to 150 kT/s, 4 to 150 kT/s, 5 to 150 kT/s. In exemplary applications, the maximum value of the magnetic flux density derivative may be at least 0.3, 0.5, 1, 2.5, 3.2, 5, 8, 10, 17, 30 or 60 kT/s. The value of the magnetic flux density derivative may correspond to an induced current in tissue.

The magnetic flux density derivative can be determined within an entire period of the magnetic signal and/or within any segment of the magnetic signal.

The device may enable continuous therapy and continuous magnetic therapy, wherein the set of magnetic flux densities and frequencies/repetition rates of the magnetic pulses are independent of the duration of the therapy and the operating temperature on the casing of the device operating at an ambient temperature of 30 °C. 60 °C, preferably 56 °C, more preferably 51 °C, even more preferably 48 °C, most preferably 43 °C.

The treatment device may include a communication module coupled with the control unit. The communication module may collect service data of the treatment device, such as number of pulses, hardware or software errors, and the like. The communication module can communicate with a remote control station, eg a server, central computer or main control center, via a datalink. The datalink may be any kind of communication link, such as a wireless Internet connection, IRDC, Bluetooth, dial-up connection, wireless such as Wi-Fi, GSM, PCS, or wired such as Ethernet. Data can be processed by software and displayed for further analysis. Data may be displayed in a mobile application. Alternatively, service data may be evaluated and any notifications provided to the end user of the treatment device. In an exemplary application, the data may correspond to treatment credits (corresponding to the treatment device or to wear and tear on its parts) and may be deducted after each treatment. The treatment device may be disabled from generating a magnetic field after credits are exhausted. Alternatively, the treatment device may be disabled from generating the magnetic field after reaching a predetermined number of treatments.

An electrical current can be induced within the treated biological structure during pulsed magnetic therapy. Due to the high value of the magnetic flux density, more specifically biological structures can be targeted and treated. The distribution of the magnetic field is uniform in biological structures. Particles (eg atoms, ions, molecules, etc.) within biological structures are affected by magnetic fields and the permeability of cell membranes may also increase.

Due to the increased permeability of cell membranes, pulsed magnetic fields can induce the following effects: at least muscle contraction; a decrease in adipose tissue-volume and/or number of adipocytes, including an increase in apoptosis index; cellulite reduction; neogenesis and/or remodeling of collagen and/or elastin fibers, ie increasing collagen and/or elastin; improving skin elasticity and/or skin texture; skin sagging relief; waist reduction. Additional magnetic therapy may improve circulation of blood and/or lymph and improve local and/or adipose tissue metabolism. Treatment with time-varying magnetic fields may also cause muscle hypertrophy and/or hyperplasia; reduce rectus abdominis muscle separation (abdominal separation); increase fat and/or basal metabolism; and/or reduce visceral fat. The treatment effect is contouring, circumferential reduction, core strengthening, body contouring, body shaping, core shaping, muscle shaping, muscle shaping, skin sagging reduction, muscle strengthening, muscle elasticity, muscle firming, muscle increase, muscle sagging relief , for example may be known as butt lifting. Additionally, treatment with a time-varying magnetic field can cause body shaping to enhance the visual appearance of the treated body region. Body shaping may include muscle hypertrophy, muscle hyperplasia, cellulite reduction, and/or fat cell reduction.

In another aspect, an improvement in the function and/or appearance of a muscle may be achieved, with results similar to physical exercise. This result can be achieved by application of high magnetic flux densities to body regions and induction of at least muscle contractions. A higher value of the applied magnetic flux density may result in a stronger muscle contraction. Repetitive application can be more efficient than standard workouts in fitness because fitness machines only strengthen isolated muscles. This result can be achieved in a very short period of time with minimal treatment time.

According to the method, the factors that improve the visual appearance of the body include treatment of the major muscles, eg, the gluteus maximus; treatment of the inner muscle, which can be made possible by high values of magnetic flux density; non-contact application of magnetic flux density, which can also be applied through clothing; stronger muscle contraction due to higher values of magnetic flux density; higher quality of muscle targeting; treatment may not be affected by minor shifts during treatment; treatment time duration may be shortened due to higher values of flux density and/or higher repetition rates; Including that delay cannot occur.

According to an exemplary application, treatment may be initiated by turning on the treatment device. An applicator comprising a coil may be placed on the patient. The magnetic flux density can be set as the highest magnetic flux density value acceptable to the patient. The highest magnetic flux density value acceptable to the patient may be a value that is sufficient to induce muscle contraction and may not cause pain to the patient. Also, the exact treatment location can be found by the operator. The precise treatment location can be found by moving the at least one applicator over the target area of the patient's body. Alternatively, a plurality of applicators may be moved simultaneously to establish a precise treatment position. The exact treatment location is the location where the induced current causes the strongest muscle contraction. At least one applicator may be held by the positioning member in a static position relative to the patient. Treatment can be initiated, i.e., a time-varying magnetic field applied to the body region for a predetermined treatment period.

In a preferred application, the magnetic field generated by the treatment device is applied to a body prone to fat accumulation and/or cellulite, such as the thighs, saddleback, buttocks, abdomen, tummy area or bra fat area or arms. can be applied to the area. Fat accumulation can be influenced by the number and/or volume of fat cells. The plurality of coils may apply a time-varying magnetic field to different body regions or to different locations of one large body region, such as the abdomen or buttocks.

The magnetic field can treat peripheral nerves within the treated body area. Alternatively, peripheral motor neurons affecting hundreds of muscle fibers can be selectively targeted. Muscle contractions of entire muscle groups stimulated by specific nerves or plexuses may also be evoked.

Due to the high magnetic flux density of the generated magnetic field, supermaximal muscle contraction can occur. Supermaximal contractions cannot be achieved spontaneously. Muscles can naturally change as they adapt to the muscle stress caused by supermaximal contractions. Thus, muscle strength and/or volume may increase. Increases in muscle strength and/or volume may be achieved by muscle fiber hypertrophy and/or muscle fiber hyperplasia. Muscle tension may also increase. These structural changes can last longer than regular exercise.

One application of time-varying magnetic fields to enhance the visual appearance of body regions may be the treatment of muscles with magnetic flux density to reduce cellulite. The magnetic flux density can be transmitted through the skin to the nerve root plate and/or innervating at least one muscle fiber. An electrical current can be induced within the target biological structure to cause at least muscle contraction. At least muscle contraction can cause movement of the epidermis, corresponding to the skin and all biological structures. In addition, at least muscle contraction can improve blood circulation either by itself or through the movement of the muscle muscle in the vicinity including the fibrous septum. Additionally, since muscle contraction can move the fibrous septa, blood and/or lymph circulation can be improved in the epidermis corresponding to these layers. In addition, local and/or adipose tissue metabolism may be improved.

By this method, muscle contraction induced by the applied magnetic flux density may help to tone the muscle to provide a more attractive appearance. As the muscle structure is treated by the time-varying magnetic field, the entire limb can be moved due to the high power of magnetic therapy. Nonetheless, the method is not limited to applications for extremities, and the method can be used for any muscle, such as the gluteus maximus muscle or any muscle/fast muscle for inducing body contouring and/or body shaping effects and fat burning. can be cured Additionally, shortened and/or stretched muscles can be stretched. The patient's physical fitness may also be improved.

The treatment may include at least 500 magnetic pulses per treatment, or at least 1000 magnetic pulses per treatment may also be applied. Alternatively, the treatment may include at least 2000, preferably at least 5000, more preferably at least 10000, even more preferably at least 20000 pulses and most preferably at least 50000 pulses per treatment. A treatment can include up to 200000 pulses per treatment.

According to one application, a time-varying magnetic field can be applied to various pulse sequences called protocols. A protocol may include multiple sections including trains and bursts. A section may include a specific train period, burst period or section period. Sections include treatment parameters such as repetition rate; number of impulses in the train; It is possible to vary the duration of the burst or the modulation of the time-varying magnetic field, ie change the treatment parameters over time, alternatively the sections can be repeated or alternated. Amplitude modulation of the time-varying magnetic field, i.e. modulation of magnetic flux density, may be used. Modulation of magnetic flux density can be interpreted as changing the amplitude of a magnetic pulse to create an envelope. Different envelopes are perceived differently by patients. Treatment results may vary depending on the protocol. The protocol may include at least two bursts or sections that differ from each other in flux density, repetition rate or impulse duration.

The train includes a plurality of subsequent magnetic pulses, ie at least two pulses. A burst includes one train and a time when no magnetic field is generated. A burst consists of a first time period and a second time period. At least one muscle contraction may occur during the first period of time. The train may last at least 4, 8, 25, 100, 200, 250, 300, 500 ms or 1, 2, 4, 5, 7.5, 10, 12.5, 15 seconds or more. Trains can likewise last for tens of seconds. Exemplary treatments may include at least 2, 5, 10, 25, 50, 100, 250 or 500 bursts. Alternatively, the treatment ranges from 15 to 25000, preferably from 40 to 10000, more preferably from 75 to 2500, even more preferably from 150 to 1500, most preferably from 300 to 750. Can contain ranges or multiple bursts up to 100000. The time between two subsequent trains may be at least 5, 10, 50, 100, 200, 500, 750 ms. Alternatively, the time between two subsequent trains, i.e., the second period of time, may last for several tens of seconds, such as 1, 2, 2.5, 5, 7.5, 10, 15, 20 seconds or more.

The repetition rate in subsequent bursts may incrementally increase/decrease in increments of at least 1, 2, 5 Hz or more. Alternatively, the flux density may be changed in subsequent bursts, such as by incrementally increasing/decreasing in increments of at least 1, 2, 5% or more of the previous burst.

A trapezoidal envelope is a train of pulses of three sub-periods, where the first sub-period T _R is a time during which the magnetic flux density increases, referred to as an increasing transient time, ie the amplitude of the magnetic flux density can increase. The second sub-period T _H is a time with the maximum magnetic flux density, that is, the amplitude of the magnetic flux density may be constant. At least two magnetic pulses are generated during time T _H , and preferably a plurality of magnetic pulses are generated.

The section duration may range from 3 to 10 seconds or up to 30 seconds. A section may preferably be repeated at least 2 times, more preferably 5, 10 or up to 30 times.

After the amplitude of the magnetic flux density reaches the maximum value, a magnetic field may be generated for a time within a range of 0.5 to 3 seconds with a constant amplitude. The magnetic flux density amplitude may then decrease to zero for a time in the range of 0.5 to 4 seconds. Then, a relaxation period may follow for a time ranging from 1 to 5 seconds, ie no time-varying magnetic field may be applied to the patient. The total time period of the burst may range from 2.25 to 13 seconds. The section duration may be in the range of 30 to 150 seconds.

The third section may include a repetition rate in the range of 25 to 60 Hz. The train can be modulated with a trapezoidal envelope in the amplitude of the magnetic flux density. A trapezoidal envelope may include increasing the transient time period in the range of 250 to 1000 ms. After the amplitude of the magnetic flux density reaches the maximum value, a magnetic field may be generated for a time within a range of 0.5 to 5 seconds with a constant amplitude. The magnetic flux density may then decrease to zero for a time in the range of 0.5 to 4 seconds. Then, a relaxation period may follow for a time ranging from 2 to 10 seconds, ie no magnetic field may be applied to the patient. The total time period of the burst may range from 3.25 to 20 seconds. The section duration may range from 50 to 250 seconds.

Magnetic treatment may be combined with adjuvant treatment methods. Examples of adjuvant treatment include the application of mechanical waves, such as acoustic waves, ultrasound or shock wave therapy; or electromagnetic waves, for example radiofrequency or diathermy therapy or light therapy, such as intense pulsed light or laser therapy; or mechanical treatment such as positive or negative pressure, rollerballs, massage, etc.; or heat treatment, such as cold therapy, or electrotherapy methods; or mesotherapy methods and/or any combination thereof. The combined method of using magnetic fields and any adjuvant treatment methods can be applied to the patient by one applicator, for example coils and different energy sources (cooling, mechanical, optical and/or RF waves) in one applicator. There may be. The magnetic field may be generated by a treatment device that is separate from other treatment devices that provide an assistive treatment method. The first applicator may include a coil and a second applicator containing an adjuvant treatment may be attached to the first applicator or vice versa. Alternatively, a first applicator comprising a coil and a second applicator comprising an adjuvant treatment may be attached to a common mechanical holder such as a platform.

Depending on the method mentioned, treatment may be continuous, pulsed, random or burst, but is not limited thereto. The impulse can be, but is not limited to, single phase, multiphase, biphasic and/or static magnetic fields. In preferred applications, the magnetic impulse can be in the biphasic regime, i.e. it consists of two phases, preferably positive and negative.
