Description

Technical Field

[0001] The present invention relates to a wearable device for outputting a magnetic field and a method for positioning an electromagnetic conversion unit thereof. Background Art

[0002] At present, transcranial magnetic stimulation technology has been widely used and applied in various fields such as neuropsychiatry, rehabilitation, and pediatrics. This technology can be used to treat patients with diseases such as depression and sleep disorders, and the non-drug transcranial magnetic stimulation treatment method has achieved gratifying results clinically.

[0003] The Chinese invention patent with the authorization announcement number CN 206964885 U discloses a magnetic output device of a transcranial magnetic stimulation device, including a housing, a base, a belt, and a ferrule. The housing is fixed on the upper surface of the base. A circular groove is provided on the upper surface of the housing, and a cylindrical knob is provided at the center of the groove. The knob vertically penetrates through the center of the housing through a lead screw. A wiring port is provided at one end of the outer surface of the housing. A coil core is provided inside the housing, and a plurality of turns of copper wire are wound around the surface of the coil core. A through hole is provided at the center of the coil core, and the lead screw passes through the through hole. A cavity is provided inside the base, and two protrusions are symmetrically provided at both ends of the outer surface of the base. The coil of this magnetic output device can adjust the size of the magnetic field by moving the coil core up and down through the lead screw, improving the focusing of the magnetic field. By sliding the base on the belt, the position of the coil core can be adjusted, thereby adjusting the position of the magnetic field.

[0004] However, when adjusting the position of the coil core in the above-mentioned magnetic output device of the transcranial magnetic stimulation device, the movement trajectory of the coil core is restricted by the belt, and the position of the coil core cannot be adjusted in all directions. This results in a small flexibility in the installation position of this magnetic output device and a small adjustable range of the output magnetic field orientation, and cannot well meet the needs of users. Therefore, it is necessary to design a head-mounted magnetic field output device with a larger adjustable range of the output magnetic field orientation. Summary of the Invention

[0028] The following will make a detailed description of the wearable device for outputting magnetic field of the present invention with reference to the drawings.

[0029] Embodiment 1 of the wearable device for outputting magnetic field of the present invention is as Figures 1 to 3As shown, it includes a wearable device 7 for electromagnetic conversion unit, which conforms to the shape of the human head (in other embodiments, the wearable device for electromagnetic conversion unit can also be set to conform to the shapes of the human chest, abdomen and limbs), is a wearable structure, worn on the human head and attached to the user's body surface. It also includes an electromagnetic conversion unit 4 (in other embodiments, multiple electromagnetic conversion units can also be provided as needed), which is used to be attached to the wearable device 7 for electromagnetic conversion unit to apply a magnetic field to the treatment target area in the human body. Magic tapes are all provided on the outer surface of the wearable device 7 for electromagnetic conversion unit, and magic tapes matching those on the wearable device 7 for electromagnetic conversion unit are provided on the electromagnetic conversion unit 4. The electromagnetic conversion unit 4 is arranged on the outer surface of the wearable device 7 for electromagnetic conversion unit through the magic tapes. Such a setting can arbitrarily adjust the position of the electromagnetic conversion unit 4 as needed, and the adjustment process is simple and convenient.

[0030] It also includes an excitation device (in other embodiments, multiple excitation devices can also be provided). The excitation device generates a driving excitation current with sufficient strength and adjustable one or more of intensity, pulse width and interval time, and outputs it to the electromagnetic conversion unit 4. The excitation device is composed of a control unit 5, an energy storage unit 2, a power release unit 3, an input unit 6 and a power supply unit 1. The control unit 5 is used for the coordinated control of each unit, and uses a single-chip microcomputer or an FPGA as the core device. The energy storage unit 2 is used to store and accumulate electric energy for high-voltage and large-current release, and uses devices such as capacitors and supercapacitors as basic energy storage components. The power release unit 3 is used to apply the electric energy of the energy storage unit 2 to the electromagnetic conversion unit 4 in the form of high voltage and large current under the instruction of the control unit 5, and uses high-power MOS transistors, high-power thyristors, etc. as basic components. The input unit 6 is used to receive external information and instructions, uses serial communication, is externally connected to a PC or a keyboard. The power supply unit 1 is used to supply electric energy to each power-consuming unit. The working modes of the excitation device are typical mode, automatic mode and self-defined mode; in the typical mode, the signals of the excitation device are applied to the applicable electromagnetic conversion unit 4 in a combination of one or more intensities, pulse widths and interval times preset for typical symptoms; in the automatic mode, the signals of the excitation device automatically select the maximum intensity that an individual can bear according to the optimized pulse width, interval time and the number of electromagnetic conversion units, and apply it to the electromagnetic conversion unit 4; in the self-defined mode, the signals of the excitation device are applied to the set electromagnetic conversion unit 4 in a combination of intensity, pulse width and interval time set by people.

[0031] The electromagnetic conversion unit 4 is composed of a coil and a magnetic conductor at the center or outside of the coil. The coil is a circular coil 8, which is wound circularly. The electromagnetic conversion units 4 are arranged in pairs, and the magnetic field directions of the individual electromagnetic conversion units 4 in each pair of electromagnetic conversion units are the same, and they are arranged relatively left and right on the outer surface of the electromagnetic conversion unit wearing device 7. The electromagnetic conversion unit 4 is wound circularly. When current passes through the coil, according to Ampere's law, a magnetic field passing through the center of the coil is generated inside the coil. (In other embodiments, when the coil of the electromagnetic conversion device is wound in a figure-eight shape, when current passes through the coil, according to Ampere's law, magnetic fields with opposite directions are generated in the two circular holes of the figure-eight coil at the same time. The path of the magnetic force lines will penetrate into one loop of the figure-eight coil and exit from the other loop.)

[0032] The electromagnetic conversion unit wearing device 7 is used to determine the type, quantity, and distribution of the electromagnetic conversion units 4 according to the intensity, direction, position, and size of the magnetic field required for treatment, and install them on the electromagnetic conversion unit wearing device 7 to form an integral body, and attach it to the human treatment area in a wearable manner.

[0033] The electromagnetic conversion unit wearing device 7 is also provided with positioning coordinates for displaying and prompting the placement position of the electromagnetic conversion units 4. The positioning coordinates are marked on the electromagnetic conversion unit wearing device 7 and are realized by the grid where the longitude line 11 and the latitude line 12 intersect; wearing marks (not shown in the figure) are provided on the front and rear of the outer surface of the electromagnetic conversion unit wearing device 7. A buckle strap (not shown in the figure) for adjusting the tightness is also provided on the outer surface of the electromagnetic conversion unit wearing device 7. After wearing, adjust the tightness of the buckle strap to fix the electromagnetic conversion unit wearing device 7 on the patient's head. The electromagnetic conversion unit wearing device 7 is customized according to the user's body size, and the manufacturing method can be made by processes such as 3D printing, textile, cutting and sewing.

[0034] Taking the example of releasing 100V, 10A, for 0.1 second, with an interval of 0.9 second, its working process is as follows: The control unit 5 first sends an instruction of 100V voltage to the energy storage unit 2 and monitors the energy storage situation. The energy storage unit 2 boosts the electrical energy transmitted by the power supply unit 1 to 100V, charges the capacitor to store electrical energy, and transmits it to the electrical energy release unit 3. Under the instruction of the control unit 5, the electrical energy release unit 3 conducts the electrical energy transmitted by the energy storage unit 2 with a current of 10A for 0.1 second to apply to the magnetic field output unit 4, and then closes for 0.9 seconds. After receiving the electrical energy of 100V, 10A, and 0.1 second, the magnetic field output unit 4 generates a magnetic field of corresponding intensity; during the 0.1 second when the electrical energy release unit 3 is conducting, the energy storage unit 2 is in a discharging state, and during the 0.9 second when the electrical energy release unit 3 is closed, the energy storage unit 2 is in a charging state.

[0035] Figure 3The schematic diagram of the coil magnetic field of the magnetic field output unit 4 in Embodiment 1 of the wearable device for outputting the magnetic field of the present invention is shown. To enable a certain magnetic field intensity to be achieved in the treatment area, two magnetic field output units 4 are arranged opposite to each other left and right, and it is ensured that the magnetic field directions generated by the two circular coils 8 are the same. The dotted lines therein are the directions of the magnetic force lines. When the current is Figure 3 in the direction of the arrow, the magnetic force lines all enter from the left end and exit from the right end of the two circular coils 8, and magnetic force lines with a direction from left to right are formed between the two circular coils 8. When a person's head is exactly in the middle of the two circular coils 8, the magnetic force lines just pass through the head. If the lesion area is exactly on the path where the magnetic force lines pass through, a magnetic field is formed within the lesion area.

[0036] When the wearable device for outputting the magnetic field of the present invention is in use, first put the electromagnetic conversion unit wearing device 7 on the patient's head, and then select the setting position of the electromagnetic conversion unit 4 according to the position of the patient's lesion area. When setting the electromagnetic conversion unit 4, it only needs to be pasted at the corresponding position on the electromagnetic conversion unit wearing device 7.

[0037] The wearable device for outputting the magnetic field of the present invention is provided with a hook surface or a loop surface on the entire outer surface of the electromagnetic conversion unit wearing device 7, and a loop surface or a hook surface that adheres to the hook and loop fastener on the outer surface of the electromagnetic conversion unit wearing device 7 is provided on the electromagnetic conversion unit 4. The setting position of the electromagnetic conversion unit 4 on the electromagnetic conversion unit wearing device 7 can be adjusted arbitrarily as needed, the adjustable range of the azimuth of the output magnetic field is increased, and the operation is simple.

[0038] As Figures 4 to 5 shown, the difference between Embodiment 2 of the wearable device for outputting the magnetic field of the present invention and the above Embodiment 1 is only that the electromagnetic conversion unit is an 8-shaped electromagnetic conversion unit 9, and the coil arranged therein is an 8-shaped coil 10. The joint part of the two annular structures of the 8-shaped electromagnetic conversion unit 9 is movable, and the plane between the two annulars can form an angle of at least 120 degrees with the joint part as the axis. When in use, adjust the angle between the two annular structures to adapt to the curvature of the body surface. The 8-shaped electromagnetic conversion unit 9 can be pasted and set at the corresponding position on the electromagnetic conversion unit wearing device 7 according to the patient's lesion area. The number of the 8-shaped electromagnetic conversion units 9 can be set as needed and does not have to be set in pairs. When the current direction is Figure 5 in the direction of the arrow shown, the current flowing into the left coil passes clockwise, generating a magnetic field with a direction from outside to inside, and when the current flows into the right coil, it passes counterclockwise, generating a magnetic field with a direction from inside to outside. Since the two coils of the 8-shaped coil 10 are adjacent, when the current direction is as Figure 5When the direction is as shown by the arrow, as known above, in the left coil, the direction of the magnetic lines of force is from top to bottom, and in the right coil, the direction of the magnetic lines of force is from bottom to top; since the two coils are adjacent, the magnetic lines of force pass through from the left coil from top to bottom and emerge from the right coil from bottom to top, that is, the circular magnetic lines of force shown in the figure are formed. When the plane formed by the figure-eight coil 10 approaches a person's head, the above-mentioned circular magnetic lines of force just pass through the person's head. If the lesion area is exactly on the path where the magnetic lines of force pass through, a magnetic field is formed within the lesion area.

[0039] In other embodiments, the outer surface of the electromagnetic conversion unit wearing device may not be provided with warp threads, weft threads, wearing marks, and buckles. At this time, the positioning effect of the wearing body is relatively poor.

[0040] In other embodiments, the winding shape of the coil can also be set as needed without necessarily being wound into a circular or figure-eight shape. For example, it can be wound into an oval shape.

[0041] In other embodiments, the input unit itself can also have input command buttons without the need to externally connect a computer.

[0042] In other embodiments, the electromagnetic conversion unit can also be adhesively attached to the electromagnetic conversion unit wearing device through double-sided tape.

[0043] The present invention also provides a method for positioning an electromagnetic conversion unit of a wearable device for outputting a magnetic field as described above, including the following steps:

[0044] Step 1, establish a three-dimensional model of the user and determine the position of the user's treatment target in the three-dimensional model;

[0045] Step 2, determine whether the treatment target position is in the central area of the user's body;

[0046] If the treatment target position is in the central area of the user's body, establish a first configuration plan for the electromagnetic conversion unit. The first configuration plan for the electromagnetic conversion unit is to select one or more pairs of circularly wound electromagnetic conversion units, and the two electromagnetic conversion units in each pair are symmetrically arranged on the outer surface of the electromagnetic conversion unit wearing device with the treatment target position as the center, and output the first configuration plan for the electromagnetic conversion unit;

[0047] If the treatment target position is not in the central area, establish a second configuration plan for the electromagnetic conversion unit. The second configuration plan for the electromagnetic conversion unit is to select one or more figure-eight wound electromagnetic conversion units, and the figure-eight wound electromagnetic conversion units are arranged on the outer surface of the electromagnetic conversion unit wearing device at a position close to the treatment target, and output the second configuration plan for the electromagnetic conversion unit;

[0048] Step 3: Based on the electromagnetic conversion unit configuration scheme output by the three-dimensional model and the position of the treatment target in the three-dimensional model, determine the position on the human body where the actual electromagnetic conversion unit wearing device should be worn, as well as the configuration scheme and setting position of the electromagnetic conversion unit on the electromagnetic conversion unit wearing device.

[0049] The electromagnetic conversion unit positioning method of the wearable device applied to output magnetic fields in the present invention can accurately position the wearing position of the electromagnetic conversion unit wearing device and the position where the electromagnetic conversion unit is set on the electromagnetic conversion unit wearing device, improving the treatment effect.

[0050] Although the present invention has been described in detail with general descriptions and specific embodiments above, some modifications or improvements can be made to it based on the present invention, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
