Description

Technical Field

[0001] The invention relates to the field of medical auxiliary instruments, and in particular to an acupuncture needle magnetizing device with magnetic strength detection function. Background Art

[0002] Acupuncture is a unique method of treating diseases in China. The magnetic round needle was developed by famous Chinese acupuncture experts from the round needle of the "Nine Needles" used in ancient acupuncture. Its magnetic head contains magnetism, which can produce a localized magnetic field on the skin. In addition, tapping the meridians and acupoints can dredge the meridians of the whole body and adjust the human body. By tapping the skin, it can also produce special stimulation to the nervous system, relieve mental tension, relax psychological pressure, and relax muscles to achieve the purpose of eliminating fatigue.

[0003] In order to ensure that the effect of the magnetic needle can remain stable, it is necessary to magnetize the magnetic needle regularly. Since the magnetization operation of the magnetic needle requires manual operation, operational errors may occur during the magnetization process, such as the magnetization time is too long, or the magnetization intensity is too high. In order to ensure the normal use of the magnetic needle, demagnetization is required, usually by adding an additional demagnetization coil for demagnetization, or by heating the magnetic needle for physical demagnetization. The installation of a demagnetization coil will increase the overall volume, and the heating demagnetization operation will cause the magnetic needle to overheat, which not only affects the material strength of the magnetic needle, but also needs to wait for cooling after heating before it can be used normally.

[0010] As an improvement of the above technical solution, both side ends of the contact electrode are provided with recessed parts, and when the contact electrode is inserted into the inside of the side groove, the recessed parts fit the surface of the electrode column or the electrode head.

[0011] As an improvement of the above technical solution, the limit block and the contact electrode are arc-shaped and fit the inner wall of the adjusting cylinder.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In order to ensure that the effect of the magnetic needle can remain stable, it is necessary to magnetize the magnetic needle regularly. Since the magnetization operation of the magnetic needle requires manual operation, operational errors may occur during the magnetization process, such as the magnetization time is too long, or the magnetization intensity is too high. In order to ensure the normal use of the magnetic needle, demagnetization is required, usually by adding an additional demagnetization coil for demagnetization, or by heating the magnetic needle for physical demagnetization. The installation of a demagnetization coil will increase the overall volume, and the heating demagnetization operation will cause the magnetic needle to overheat, which not only affects the material strength of the magnetic needle, but also needs to wait for cooling after heating before it can be used normally.

[0021] To solve the above problems, see Figures 1 to 7 , provides an acupuncture needle magnetizing device with magnetic strength detection, including: a base 10 and a storage tube 30 rotatably arranged on the upper end of the base 10.

[0022] Specifically, a power supply module is provided inside the base 10, and an electrode column 22 and an electrode head 23 electrically connected to the power supply module are provided on the inner side of the base 10. An electromagnetic coil 34 is embedded in the inner wall of the storage tube 30, and the electromagnetic coil 34 has two contact electrodes 33. A through inner cavity three 31 is opened at the center position of the storage tube 30, and a magnetic field sensor 32 is detachably connected to the opening at the lower end of the inner cavity three 31. The contact electrode 33 is inserted into the interior of the base 10, and the storage tube 30 is rotated until the contact electrode 33 that switches contact with the electrode column 22 and the electrode head 23 makes the internal magnetic field direction opposite.

[0023] The power supply module provides overall power supply, and the power supply current is conducted to the contact electrode 33 through the electrode column 22 and the electrode head 23, and then transmitted to the electromagnetic coil 34 by the contact electrode 33. The electromagnetic coil 34 forms a magnetic field for magnetization operation. During the magnetization process, the magnetic needle needs to be placed inside the storage tube 30. During the operation, the strength of the magnetic field is detected by the magnetic field sensor 32. When the magnetic strength of the magnetic needle is too high due to erroneous operation, the storage tube 30 is rotated so that the contact electrodes 33 connected to the electrode column 22 and the electrode head 23 are opposite. In this way, when power is turned on in the front and back states, the current flows in opposite directions, and the magnetic field generated when it passes through the electromagnetic coil 34 is also opposite. In this case, if the position of the magnetic needle remains unchanged, the originally charged magnetism will be partially offset, thereby weakening the magnetic strength of the over-charged part. When it returns to the normal range of use, the power supply can be disconnected.

[0024] In the above scheme, only the magnetization and demagnetization state of the magnetic needle can be adjusted, but the magnetization intensity during the magnetization process cannot be adjusted. In order to ensure the adjustability of the electromagnetic intensity, please refer to Figures 1 to 4 The power supply module includes a rheostat and a power supply board 12 arranged inside the base 10. The base 10 has an inner cavity 11 running through one end. The rheostat is arranged inside the inner cavity 11. The electrode column 22 is electrically connected to the rheostat. The other end of the rheostat is electrically connected to the power supply board 12. The power supply board 12 is electrically connected to an electrode wire 121, and the electrode wire 121 is electrically connected to the electrode head 23.

[0025] The current is adjusted by a rheostat, which is connected to the rheostat through the electrode column 22, and the rheostat is connected to the power supply board 12. The electrode line 121 is separately connected to the power supply board 12 and the electrode head 23, forming a complete current flow direction. The current flows from the rheostat and the electrode column 22 through the electromagnetic coil 34, and then returns to the electrode head 23 and the electrode line 121 to flow to the power supply board 12. Since the voltage of the power supply board 12 itself remains unchanged, it is only necessary to adjust the resistance of the rheostat to adjust the current in the circuit. Different currents will cause the magnetic field generated by the electromagnetic coil 34 to change, thereby achieving the purpose of controlling the magnetization intensity.

[0026] In one embodiment, see Figure 1 , Figure 2 and Figure 8 A mounting groove is formed at one end of the base 10 away from the inner cavity 11, and a power supply board 12 is arranged inside the mounting groove. A bottom cover 101 is detachably fixed at the notch of the mounting groove.

[0027] The bottom is closed by the bottom cover 101, and the power supply board 12 is arranged inside. When a fault occurs, the bottom cover 101 can be removed to inspect the power supply board 12.

[0028] For further controllability of the rheostat adjustment, see Figures 1 to 8 The variable resistor includes an adjusting cylinder 20 threadedly connected to the inner wall of the inner cavity 11, a barrier cylinder 13 detachably fixed to the bottom of the inner cavity 11, and a resistance wire 132 wound on the outside of the barrier cylinder 13, one end of the resistance wire 132 is connected to the power supply board 12 through a wire, an electrode column 22 and an electrode head 23 are fixed to the inner wall of the adjusting cylinder 20, and a contact electrode 33 is inserted into the interior of the adjusting cylinder 20. A protrusion 221 is integrally formed at one end of the electrode column 22 close to the bottom of the inner cavity 11, and the protrusion 221 is close to the resistance wire 132. An inner cavity 131 passing through both ends is opened inside the barrier cylinder 13, and the electrode wire 121 penetrates into the inner cavity 131 and penetrates to the other end of the base 10 to be electrically connected to the power supply board 12. When the adjusting cylinder 20 rotates, the electrode column 22 spirally rotates along the cross-section of the resistance wire 132 to adjust the resistance on the path through which the current passes.

[0029] The adjustment function on the outside is provided by the adjustment cylinder 20 connected by a thread. When the adjustment cylinder 20 is rotated, the electrode column 22 fixed on the inner wall of the adjustment cylinder 20 will rotate along with it. Since the electrode column 22 is in close contact with the protrusion 221 of the resistance wire 132, when the electrode column 22 rotates, the protrusion 221 will rotate along the outer spiral of the barrier cylinder 13. During the rotation process, the length of the resistance wire 132 between the protrusion 221 and the power supply board 12 will change. If the length of the resistance wire 132 between the two increases, the resistance connected to the circuit will increase. When the length of the resistance wire 132 is reduced, the resistance connected to the circuit is reduced. During the rotation, the electrode head 23 at the end of the electrode wire 121 will rotate accordingly, so the electrode wire 121 will also be pulled. In this case, the electrode wire 121 may be in a tangled state, but because the electrode wire 121 is inserted into the inner cavity 131, the electrode wire 121 will not affect the resistance wire 132 and the electrode column 22. It is only necessary to set the length of the electrode wire 121 to a slightly longer state and keep the electrode wire 121 in a relaxed state. Figure 3 The curved design.

[0030] In the above solution, the connection between the electrode column 22, the electrode head 23 and the contact electrode 33 may be loose or have poor contact. In order to strengthen the connection between the structural parts, please refer to Figures 1 to 4At least two groups of limit blocks 21 are provided on the inner wall of the adjustment cylinder 20. A penetrating electrode groove 211 is provided on the surface of the limit block 21 on one side facing the electrode column 22 and the electrode head 23. The electrode column 22 and the electrode head 23 are vertically inserted into the electrode groove 211. A side groove 212 penetrating to the other side is provided on one side of the limit block 21. The contact electrode 33 is a horizontally arranged arc-shaped block structure. One side of the contact electrode 33 is inserted into the side groove 212. The storage cylinder 30 is rotated until the contact electrode 33 is inserted into the side groove 212 in the opposite direction, and the contacting electrode column 22 and the electrode head 23 are switched so that the internal magnetic field direction is opposite.

[0031] The electrode column 22 and the electrode head 23 are restricted inside the electrode groove 211, and position restrictions are formed by opening side grooves 212 on both sides. Firstly, the contact electrode 33 can be positioned, and secondly, the position of the contact electrode 33 is restricted, thereby ensuring that the contact electrode 33 can accurately contact the electrode column 22 and the electrode head 23, and ensuring the tightness of the connection between them.

[0032] In addition, in order to enhance the connection effect after insertion, insulating rubber can be provided on the inner wall of the side groove 212, and the internal height of the groove opening of the side groove 212 should be slightly lower than the contact electrode 33, and the entrance can be the same as or slightly larger than the contact electrode 33. When the contact electrode 33 is inserted into the interior, the protruding positions blocked on both sides will be squeezed open, and the resilience of the rubber will fit the contact electrode 33, thereby ensuring the tightness of the connection.

[0033] In order to further facilitate the disassembly of the adjustment tube 20 and the storage tube 30, please refer to Figures 1 to 11 The limit block 21 and the contact electrode 33 are arc-shaped and fit the inner wall of the adjustment tube 20. The side groove 212 and the center position of the contact electrode 33 are on the same horizontal plane. The arc length of the contact electrode 33 is smaller than the arc length of the line connecting the edges of the same side of the two limit blocks 21 along the inner wall of the adjustment tube 20.

[0034] When the contact electrode 33 is inserted into the side groove 212, in addition to forming a circuit path, it also forms a position restriction on the top storage tube 30, thereby ensuring the stability of the structural connection. In this solution, hard plastic can also be set on the upper and lower sides of the limit block 21 to enhance its strength and avoid the weight of the entire storage tube 30 being pressed on the limit block 21.

[0035] During the rotation process, when the contact electrode 33 rotates out from the inside of the side groove 212, the top storage tube 30 has no connection. In this case, the storage tube 30 can be directly removed. If the rotation continues, the contact electrode 33 will be inserted into the side groove 212 on the other side, thereby forming a switch in the current direction and completing the position restriction of the storage tube 30.

[0036] In order to further strengthen the tightness of the connection between the contact electrode 33 and the electrode column 22 and the electrode head 23, please refer to Figure 4 as well as Figures 9 to 11 Both side ends of the contact electrode 33 are provided with recessed portions 331 . When the contact electrode 33 is inserted into the side groove 212 , the recessed portions 331 fit the surface of the electrode column 22 or the electrode head 23 .

[0037] By contacting the electrode column 22 or the electrode head 23 with the recessed portion 331, a larger contact area can be formed, and since the contact position is not a single-surface contact but a multiple-surface contact, when shaking occurs, there is mutual restriction between the multiple surfaces, thereby further strengthening the connection effect between the structures. In addition, grooves can be opened on the surface of the electrode column 22 or the electrode head 23, and the recessed portion 331 can be snapped into the opened groove, thereby further strengthening the connection between the structural parts.

[0038] To ensure the normal power supply of the magnetic field sensor 32, please refer to Figure 2 and Figure 3 A power supply line 122 is connected to the side of the magnetic field sensor 32 away from the inner cavity three 31 , and the other end of the power supply line 122 penetrates into the inner cavity two 131 and passes through to the other end of the base 10 to be electrically connected to the power supply board 12 .

[0039] Similar to the electrode head 23, a separate power supply line 122 is led out for power supply. The difference is that the connection line led out of the electrode head 23 is a single electrode line 121, while the connection line led out of the magnetic field sensor 32 is a complete power supply line 122, which can be powered independently. Similarly, the power supply line 122 needs to be set as follows Figure 3 The state shown in the figure is that it is set in a bent state. This design can provide a certain rotation range for the power line 122 to be twisted due to the rotation of the storage tube 30, thereby avoiding the power line 122 from twisting and breaking due to excessive rotation.

[0040] In the above schemes, the specific power supply method of the power supply board 12 is not involved. In the generation of the magnetic field, if the current is low, the magnetic field strength may be insufficient and the magnetic field that can be magnetized cannot be generated normally. The current of the battery is usually low. In order to ensure the current strength, please refer to Figure 1 , Figure 2 and Fig.10 A charging port 102 and a display screen 103 are detachably fixed to the outer side of the base 10 , and both the charging port 102 and the display screen 103 are electrically connected to the power supply board 12 .

[0041] That is, the external power supply is connected through the charging port 102, and the power supply board 12 is used to convert the AC power flowing into the outside into DC power, and provide voltage stabilization and filtering functions to ensure that the current connected to the electromagnetic coil 34 is stable DC power, thereby ensuring the use of the equipment.

[0042] To further ensure the disassembly of the structural parts, please refer to Figures 2 to 5 The storage tube 30 includes two concentrically nested limiting tubes 302, and the bottom of the limiting tube 302 is integrally formed with a bottom plate 301. The electromagnetic coil 34 is arranged in the gap between the two limiting tubes 302. The end of the electromagnetic coil 34 passes through the other end of the bottom plate 301 and is connected to the contact electrode 33. The contact electrode 33 is fixedly connected to the bottom plate 301. The end of the limiting tube 302 away from the bottom plate 301 is detachably fixed with a top cover 35.

[0043] That is, the electromagnetic coil 34 is directly placed in the gap between the limiting cylinders 302, and its lower end directly penetrates to the outside of the bottom plate 301. When disassembling, it is only necessary to remove the top cover 35 on the limiting cylinder 302, and then remove the connection between the contact electrode 33 and the electromagnetic coil 34.

[0044] The fixing method between the contact electrode 33 and the base plate 301 and between the contact electrode 33 and the electromagnetic coil 34 is an existing solution and is not described in detail in this embodiment. It can usually be fixed by an insert-type snap-on method or a screw-positioning method. The connection between the electromagnetic coil 34 and the contact electrode 33 can be fixed by an insert-type method, and the screw can be inserted into the radial position for fixing.

[0045] To further ensure the stability of the position of the acupuncture needles during the magnetization process, please refer to Fig.12 and Fig.13 Specifically, the inner wall of the storage tube 30 is integrally formed with a plurality of limiting tubes 36, and the limiting tubes 36 are used to insert and store the magnetic round needles.

[0046] The position is limited by inserting the magnetic round needle into the interior of the limiting tube 36. The limiting tube 36 can be made of a rubber-type material, which has a certain strength and can provide elastic deformation ability to rebound, thereby tightly locking the position of the magnetic round needle.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
