[0027] Magnetic stimulation therapy is a medical device that uses magnetic fields for non-invasive treatment. It can be used for the diagnosis and treatment of neurological and mental diseases. Its working principle is to generate induced current in human tissues through rapidly changing magnetic fields, which stimulate nerve cells and thus regulate nerve activity.

[0028] A magnetic stimulation therapy device may include a magnetic stimulation unit and a coil assembly. The coil assembly may be electrically connected to the magnetic stimulation unit for applying magnetic stimulation to target areas of the patient, such as the pelvic floor, head, sacral nerves, or other peripheral muscles and nerves. The magnetic stimulation unit discharges onto the stimulation coils to generate a pulsed magnetic field. The magnetic stimulation therapy device may also include a liquid-cooled unit, connected to the coil assembly, for supplying a cooling medium to the coil assembly via a liquid circuit for cooling.

[0029] When medical magnetic stimulation devices are in operation, the stimulation coil outputs magnetic pulses according to parameters. During this process, a large current pulse flows through the stimulation coil, causing its temperature to rise. Therefore, magnetic stimulation devices typically include a liquid cooling system to cool the stimulation coil through the circulation of cooling water. In related technologies, the stimulation coil and magnetic core are usually encapsulated in a housing and installed under a sofa seat. Cooling water enters the housing through an inlet and flows over the coil surface to cool the high-temperature coil. However, the water pressure generated during coil operation and the encapsulation process of the coil components can affect the sealing of the housing, making it prone to cooling water leakage.

[0030] The existing technology has the following drawbacks: 1) If the cooling water leaks, the amount of water in the water tank of the cooling system will decrease. When the water level drops to a certain level, the cooling system will issue an alarm. At this time, the user needs to confirm the cause of the alarm. However, it is difficult to quickly confirm whether the problem with the cooling system is caused by the cooling water leak in the relevant technology.

[0031] 2) If there is a cooling water leak, it is also impossible to quickly identify the area where the cooling water flows after the leak, thus making it impossible to promptly identify whether the cooling water has flowed out of the shell and into the sofa, which could lead to a short circuit or even a safety hazard.

[0032] In this regard, this utility model proposes a medical device for magnetic stimulation, such as a pelvic floor magnetic stimulator, a transcranial magnetic stimulator, or a multi-purpose magnetic stimulator, etc., which is not limited here.

[0033] Reference Figures 1 to 6 In one embodiment of the present invention, the medical device includes a magnetic stimulation body 10, the magnetic stimulation body 10 includes a first housing 11 and a coil assembly 12, the coil assembly 12 can be encapsulated inside the first housing 11; a second housing 20 is used to accommodate the magnetic stimulation body 10, the second housing 20 and the first housing 11 surround to form a storage cavity 20a, the storage cavity 20a is used to accommodate cooling medium leaking from the magnetic stimulation body 10.

[0034] In this embodiment, the first housing 11 may include at least one component. The first housing 11 is the outer shell of the coil assembly 12. The overall shape of the outer shell can match the shape of the coil assembly 12 of the magnetic stimulation body 10. Specifically, the shape of the outer shell can match the double "U" shape of the coil assembly 12 to ensure the reliability and compactness of the overall structure of the magnetic stimulation body 10. Of course, for other considerations, the shape of the outer shell and the coil assembly 12 can also be designed to be different, which is not limited here.

[0035] The coil assembly 12 can adopt a conventional magnetic stimulation coil structure or an unconventional improved magnetic stimulation coil structure. There is no limitation here. The present invention will be described in detail later with the improved magnetic stimulation coil structure.

[0036] The second housing 20 may have an open structure to form a receiving groove 20b for mounting the magnetic stimulation body 10. The receiving groove 20b and the first housing 11 enclose a storage cavity 20a. Alternatively, the second housing 20 may be formed as a closed hollow structure, or together with the magnetic stimulation body 10, it may form a closed hollow structure. No limitation is made here.

[0037] It should be noted that the treatment principle of the magnetic stimulation medical device is that, according to Faraday's law of electromagnetic induction, the coil assembly 12 generates a time-varying magnetic field (pulse magnetic field) after being energized. The magnetic field penetrates the skin, skull or other tissues and induces eddy currents (induced currents) in the conductive nerve tissue of the target area (such as the cerebral cortex, peripheral nerves, pelvic floor muscles), thereby activating or inhibiting neuronal activity.

[0038] It is understood that this utility model improves the cooling system structure of the stimulation coil 122 of the medical device. By setting a second housing 20 to form a storage cavity 20a with the first housing 11 of the coil assembly 12, it is used to receive and store the coolant leaking from the first housing 11, which greatly improves the sealing performance of the magnetic stimulation structure of the medical device and effectively prevents the coolant from leaking to other parts of the medical device.

[0039] In one embodiment, reference is made to Figures 1 to 6 When the second housing 20 adopts an open structure, the second housing 20 is provided with the aforementioned receiving groove 20b for accommodating the magnetic stimulation body 10. The bottom wall and part of the side wall of the receiving groove 20b, together with the bottom wall and part of the side wall of the first housing 11, form a storage cavity 20a. In this way, it is possible to receive and store leaked coolant, while facilitating manufacturing and assembly, and the overall magnetic stimulation structure is also more compact.

[0040] Furthermore, mainly referring to Figure 4A portion of the bottom wall of the base 111 of the first housing 11 can contact the bottom wall of the receiving groove 20b to divide the storage cavity 20a into a first inner cavity 20a1, a second inner cavity 20a2, and a third inner cavity 20a3. The first inner cavity 20a1 and the third inner cavity 20a3 are located on opposite sides of the second housing 20 and are respectively formed by portions of the side walls and bottom walls of the second housing 20 and the first housing 11. The second inner cavity 20a2 is located in the middle of the second housing 20 and is formed by portions of the bottom wall of the second housing 20 and the first housing 11. In this way, while achieving the water storage function, the structural strength, stability, and compactness of the medical device can be further improved.

[0041] To further improve the structural compactness and stability of this medical device, the main references are... Figure 2 and Figure 4 In this embodiment, the receiving groove 20b may include a supporting portion 20b1 and a receiving portion 20b2 communicating with the supporting portion 20b1. The magnetic stimulation body 10 is divided into a first portion 101 and a second portion 102. The length of the supporting portion 20b1 is greater than the length of the receiving portion 20b2 (the length direction is...). Figure 4 (as shown in the horizontal direction) to form a support arm at the connection between the two, the support portion 20b1 is used to accommodate and support the first portion 101 of the magnetic stimulation body 10 and to cover the opening of the receiving portion 20b2 with the magnetic stimulation body 10, and the receiving portion 20b2 is used to accommodate the second portion 102 of the magnetic stimulation body 10 and to surround the second portion 102 to form a storage cavity 20a.

[0042] To ensure the effectiveness of magnetic stimulation and further improve the ease of assembly and the compactness of the structure, in one embodiment, reference is made to... Figures 1 to 6 The coil assembly 12 may include a magnetic core 121 and a coil 122. The magnetic core 121 includes two adjacent U-shaped magnetic blocks, and the coil 122 surrounds the adjacent part of the two U-shaped magnetic blocks. The first housing 11 includes a base 111 and a cover plate 112. The shape of the base 111 is adapted to the shape of the bottom of the two adjacent U-shaped magnetic blocks to form an encapsulation groove for accommodating the coil assembly 12. The cover plate 112 covers the encapsulation groove.

[0043] Specifically, the shape of the base 111 of the magnetic stimulation body 10 is adapted to the bottom shape of the two U-shaped magnetic cores 121 after potting and shaping. The base 111 of this shape has a gap between the bottom and the second housing 20 to form a storage cavity 20a to store coolant.

[0044] In this embodiment, the cover plate 112 can be a coil circuit board electrically connected to the coil 122. A temperature sensor is integrated on the coil circuit board to detect the internal temperature of the magnetic stimulation body 10. The coil circuit board is suitable for electrical connection to the stimulation host. This significantly improves the compactness of the magnetic stimulation structure of the medical device, while simultaneously enabling real-time monitoring of the internal coolant temperature of the magnetic stimulation body 10, which is beneficial for improving the therapeutic effect and stability of the medical device.

[0045] In this embodiment, the cover plate 112 is sealed with a coil monitoring circuit board, mainly for temperature detection. The circuit board with a temperature sensor is directly used as the cover plate 112 for the coil 122. The cover plate 112 can be sealed with the first housing 11 by epoxy resin, which improves the strength of the cover plate 112 and protects the temperature sensor from damage by external forces.

[0046] After the magnetic stimulation body 10 is assembled, it is installed inside the second housing 20, which provides secondary protection. After the magnetic stimulation body 10 is installed inside the second housing 20, it is secured with several M4×12 Phillips head screws. Then, epoxy resin is injected onto the surface of the magnetic stimulation body 10. The cover plate 112 is then snapped onto the second housing 20 and secured with several M3×8 Phillips head screws.

[0047] Of course, in some other embodiments, the cover plate 112 may also be made of plastic or metal, and the specific material is not limited here.

[0048] To facilitate the arrangement of the wires connecting the coil assembly 12 and the installation of coolant inlet and outlet pipes, thereby improving the integrity of the magnetic stimulation structure of the medical device, in one embodiment, refer to Figures 1 to 6 The second housing 20 and the first housing 11 may also enclose a wiring cavity 20c that is separated from the storage cavity 20a. The wiring cavity 20c is used to accommodate pipes and cables.

[0049] To further enhance the leakage prevention effect of the magnetic stimulation structure of the medical device, based on the above embodiment, the storage cavity 20a and the wiring cavity 20c can be separated by a baffle 201. The baffle 201 is connected to or integrally formed with the side wall of the storage cavity 20a. That is, the baffle 201 can be part of the side wall or fixed to the side wall by welding or bonding. The baffle 201 extends along the bottom direction of the first part 101 close to the magnetic stimulation body 10 to abut against the first housing 11, so as to support the end of the magnetic stimulation body 10 and increase the volume of the storage cavity 20a.

[0050] Specifically, the water storage capacity of the storage chamber 20a can be set to around 800ml. If the cooling system alarms due to coolant leakage, an alarm signal will be issued when the leakage reaches around 600ml. This will alert the user to address the coolant leakage issue before the leakage exceeds the maximum load of the storage chamber 20a, preventing excessive leakage from causing further coolant leaks.

[0051] In one embodiment, primarily referring to Figure 3 The medical device may also include a leak-proof component 30, and the second housing 20 has a detection hole 20d that communicates with the storage cavity 20a. The detection hole 20d is sealed by the leak-proof component 30.

[0052] In this embodiment, the leak-proof component 30 may include a sealing post and a shielding plate connected to the sealing post. The sealing post is inserted into the detection hole 20d, and the shielding plate covers the detection hole 20d. The leak-proof component 30 may be made of a flexible material such as silicone.

[0053] The medical device of this utility model is provided with a detection hole 20d, which is sealed by a leak-proof component 30. If the cooling system triggers a liquid level alarm, the user can remove the leak-proof component 30 to quickly confirm whether the liquid level alarm is caused by a coolant leak. This greatly improves the convenience of checking whether the cooling medium in the coil assembly 12 has leaked, and can quickly locate the cause of the fault or quickly eliminate one of the causes of the liquid level alarm, so that the user can repair the medical device in time or take other fault location measures in time.

[0054] To achieve a circulating supply of coolant to the magnetic stimulation body 10 and thus enhance the therapeutic effect, in one embodiment, the following is mainly referred to Figures 5 to 7 The medical device may further include a liquid cooling unit 40, which is connected to the magnetic stimulation subject 10 via a liquid supply line 50 and is used to supply cooling medium to the magnetic stimulation subject 10. A first liquid level sensor is provided in the storage chamber 20a for detecting the liquid level in the storage chamber 20a, and the first liquid level sensor is electrically connected to the liquid cooling unit 40. The first liquid level sensor monitors the coolant level in the storage chamber 20a in real time, allowing the liquid cooling unit 40 to determine whether coolant leakage has occurred in the magnetic stimulation subject 10 and to assess the extent of the leakage.

[0055] In this embodiment, the liquid supply pipeline 50 may be a circulating liquid supply pipeline including an inlet pipeline 51 and an outlet pipeline 52. The first housing 11 is provided with an inlet for allowing the inlet pipeline 51 to pass through and an outlet for allowing the outlet pipeline 52 to pass through on the side near the wiring cavity 20c. The first housing 11 is provided with an inlet pipe interface 511 and an outlet pipe interface 521. The inlet pipe interface 511 may be located at the end of the first housing 11 away from the inlet, and the outlet pipe interface 521 may be located at the end of the first housing 11 near the outlet.

[0056] Under normal circumstances, the coolant flows through the inlet pipe 51 to the inlet port 511, then diffuses from the inlet port 511 towards the surface of the coil 122, flows on the surface of the coil 122, and then enters the outlet port 521 before flowing out through the outlet pipe 52, thus achieving a circulating supply of coolant. The design of the inlet port 511 allows the coolant to be directly delivered to the rear end of the coil 122 by the inlet pipe 51, avoiding the insufficient water flow dynamics at the rear end of the liquid path in related technologies, and solving the problem of poor coolant flow due to air bubbles at the rear end of the liquid path.

[0057] Additionally, the magnetic stimulation body 10 may also be provided with a coil port for the lead wire of the coil 122 to pass through, the coil port including the inlet port and the outlet port of the coil 122. In this embodiment, silicone can be used to seal the coil port and the aforementioned pipe interfaces and other openings to prevent coolant from overflowing from locations other than the guide port on the water outlet connector.

[0058] In this embodiment, when the first liquid level detector detects that the water volume in the storage chamber 20a has reached a preset value or the water level has risen to a preset value, it sends a feedback to the liquid cooling host 40. The liquid cooling host 40 can issue an audible or visual warning to alert the user that there is a coolant leak and that the coolant has flowed into the storage chamber 20a. The preset value can be set to a range greater than 0 and less than 650 ml (the capacity of the liquid storage tank 41 described below).

[0059] In related technologies, when the cooling system issues an alarm, maintenance personnel need to disassemble the rear cover of the liquid cooling unit to drain the water from the tank. They then need to observe the remaining water level through a sight glass located at the corresponding position on the rear cover. If the water level drops, it indicates a cooling water leak. This confirmation method is cumbersome, complex, and inefficient. If a drop in the water level sight glass indicates a cooling water leak, determining the direction of the leak requires disassembling the housing of the coil assembly 12; otherwise, it's impossible to determine whether the cooling water is flowing into the housing or into the interior of the unit.

[0060] In view of this, the present invention has made further improvements: In one embodiment, primarily referring to Figure 6 and Figure 7 The liquid cooling host 40 may include a controller, a liquid storage tank 41, and a second liquid level sensor 42 disposed in the liquid storage tank 41. The liquid storage tank 41 is connected to the magnetic stimulation body 10 through a liquid supply pipeline 50. The second liquid level sensor 42 is electrically connected to the controller and is used to detect the liquid level of the liquid storage tank 41. The capacity of the storage cavity 20a is greater than or equal to the volume of the liquid storage tank 41 above the liquid level alarm line of the second liquid level sensor 42.

[0061] In this embodiment, the coolant circulates between the storage tank 41 and the magnetic stimulation unit 10 through the supply pipe 50. When the liquid level in the storage tank 41 is lower than a preset value, the liquid cooling unit 40 can issue an alarm. Since the capacity of the storage tank 41 above the liquid level alarm line is less than or equal to the capacity of the water storage chamber, the water storage chamber can store water up to the point where a coolant leak occurs when the outer casing seal of the coil assembly 12 fails. In other words, this setting ensures that no coolant will flow outside the storage chamber 20a before the alarm is issued, thus solving the problems of short circuits and corrosion of the internal wiring of the sofa after coolant leakage in a low-cost manner, thereby avoiding safety hazards.

[0062] This utility model also proposes a magnetic stimulation therapy device, referring to... Figures 1 to 7 The magnetic stimulation therapy device includes a medical device for magnetic stimulation, a liquid-cooled main unit 40, and a stimulation main unit. The medical device for magnetic stimulation includes a magnetic stimulation body 10 and a second housing 20. The magnetic stimulation body 10 includes a first housing 11 and a coil assembly 12, the coil assembly 12 being encapsulated within the first housing 11. The second housing 20 is used to house the magnetic stimulation body 10, and the second housing 20 and the first housing 11 form a storage cavity 20a, which is used to house cooling medium leaking from the magnetic stimulation body 10. The second housing 20 is provided with a receiving groove 20b for housing the magnetic stimulation body 10, and the bottom of the receiving groove 20b... The wall and part of the sidewalls of the first housing 11 are arranged to form a storage cavity 20a. Part of the bottom wall of the first housing 11 contacts the bottom wall of the receiving groove 20b to divide the storage cavity into a first inner cavity 20a1, a second inner cavity 20a2, and a third inner cavity 20a3.
