Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a multi-frequency adjustable pulse magnetic field stimulator. Background Technology

[0002] Magnetic field stimulators, also known as transcranial magnetic field stimulators, are mainly used for central and peripheral nerve stimulation. They can also be used in neurophysiological examinations, rehabilitation neurological function assessments, psychiatric and neurological motor nerve function assessments, and therapeutic research.

[0003] When using a magnetic therapy device, the patient needs to wear the magnetic therapy cap on their head. However, if the patient gets up or moves their body during the wearing process, the connection between the magnetic therapy cap's connector and plug may become loose, which may cause the magnetic therapy cap to lose power or become loose, affecting the patient's treatment effect.

[0004] Therefore, we propose a multi-frequency adjustable pulsed magnetic field stimulator to address the problems mentioned above. Utility Model Content

[0025] The wire harness assembly 7 includes a fixed shaft 71 rotatably connected to the rear side of the inner cavity of the groove near one side and a rotating toothed roller fixedly mounted on the fixed shaft 71. Both sides of the rotating toothed roller are engaged with L-shaped toothed plates 72. An L-shaped connecting rod 73 is fixedly mounted on one side of the L-shaped toothed plate 72, and the front end of the L-shaped connecting rod 73 moves through the inner cavity of the L-shaped groove and is fixedly mounted with a sliding block 75.

The arc-shaped clamping plates 77 are respectively fitted to the adjacent connectors 4.

[0026] Specifically, when connector 4 is inserted into the outer periphery of plug 6, with the cooperation of wire harness assembly 7, the outer periphery of connector 4 can be restrained by arc-shaped clamp 77 through the cooperation of telescopic rod A761 and spring A762, which can improve the stability of connector 4 inserted into the outer periphery of plug 6, thereby preventing power failure of magnetic therapy cap 3 during use and improving the therapeutic effect of the device.

[0027] Several telescopic rods A761 are fixedly installed on the opposite side of the movable plate 76. The opposite ends of the telescopic rods A761 are fixedly connected to the top and bottom of the adjacent groove cavity, respectively. Springs A762 are movably sleeved on the outer periphery of the telescopic rods A761, and the two ends of the springs A762 are fixedly connected to the adjacent movable plate 76 and the groove cavity, respectively.

[0028] Specifically, by setting the telescopic rod A761 and the spring A762, the arc-shaped clamp 77 can be tightly limited to the joint 4.

[0029] Locking casters 11 are fixedly installed on the bottom of the main body 1 of the magnetic therapy device near all four sides. Handles 13 are fixedly installed on the other side of the main body 1 near the front and rear sides. Two winding racks 12 are fixedly installed on one side of the main body 1 near the top, and the winding racks 12 are arranged vertically.

[0031] Example 2

[0032] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 2 , Figure 4 and Figure 5The protective component 5 includes a protective shield 51 that moves through the inner cavity of the rectangular groove and a magnetic block A52 fixedly installed on the front side near the bottom of the protective shield 51. A magnetic block B53 is fixedly installed on the front side near the bottom of the magnetic block A52. A magnetic block D55 and a magnetic block C54 are fixedly installed at the top and bottom of the inner cavity of the groove, respectively. Magnetic blocks B53 and C54 have different magnetic properties, and magnetic blocks D55 and A52 have different magnetic properties.

[0033] Specifically, when protecting the plug 6, the protective cover 51 can be moved downwards, and the magnetic block B53 and magnetic block C54 fixed on the protective cover 51 can be magnetically attracted to each other. This can prevent foreign objects from being inserted into the inner cavity of the plug 6, which would damage it and cause the plug 6 to become unusable in the future.

[0034] Limiting grooves 512 are provided on both sides of the inner cavity of the rectangular groove. Limiting blocks 511 are fixedly installed on both sides of the protective shield 51 near the top. The limiting blocks 511 are slidably connected in the inner cavity of the adjacent limiting grooves 512. Rolling balls 513 are movably installed in the inner cavity of the limiting blocks 511. Rolling grooves 514 are provided on the side of the inner cavity of the limiting grooves 512 that are far apart. The rolling balls 513 are slidably connected in the inner cavity of the adjacent rolling grooves 514.

[0035] By setting the ball bearings 513 and the grooves 514, the protective cover 51 can be moved smoothly.

[0036] Working principle: When using this utility model, if it is necessary to insert the connector 4 into the outer periphery of the plug 6, the operator can push the protective cover 51 upwards, causing the magnetic block A52 and magnetic block D55 fixed on the protective cover 51 to attract each other magnetically. At this time, the operator can insert the connector 4 into the outer periphery of the plug 6. During the insertion process, pushing the sliding block 75 upwards will cause the L-shaped connecting rod 73 fixed on the sliding block 75 to connect and move the adjacent L-shaped rack plate 72 upwards. The rotating toothed roller and the adjacent L-shaped rack plate 72 move upwards. When used in conjunction with 2, the two arc-shaped clamps 77 can be moved to opposite sides, and then the connector 4 can be inserted into the outer periphery of the plug 6. When the sliding block 75 is released, the arc-shaped clamps 77 can be attached to the outer periphery of the connector 4 in conjunction with the telescopic rod A761 and the spring A762, which can prevent the connector 4 from accidentally falling off during use. When not in use, the protective cover 51 can be moved downward to attach the magnetic block B53 and the magnetic block C54 and fix them magnetically, which can protect the plug 6 and prevent foreign objects from being inserted into the inner cavity of the plug 6.
