Description

Technical Field

[0001] The invention belongs to the technical field of magnetic therapy equipment, and in particular relates to a self-service magnetic therapy device. Background Art

[0002] The application background technology of existing pulsed magnetic therapy devices in orthopedic high-frequency treatment rooms is mainly based on the biological effect mechanism of pulsed electromagnetic fields (PEMF). It mainly stimulates bone cell metabolism and calcium ion channel activity through pulsed magnetic fields of specific frequency and intensity, promotes osteoblast proliferation and callus formation, and thus accelerates fracture healing. Pulsed magnetic therapy devices are usually composed of a magnetic field generator, a control module, and a targeted treatment head. They use a multi-coil array design to enhance the penetration depth of the magnetic field and optimize the energy output efficiency through real-time impedance matching technology. The clinical application of pulsed magnetic therapy devices is concentrated on orthopedic diseases such as osteoporosis, fracture repair, and arthritis.

[0003] The pulse magnetic therapy device includes a U-shaped magnetic therapy head, which needs to be covered by medical staff on the patient's flat limbs when in use. In actual operation, the patient's treatment part is first set on the supporting structure, and then the treatment head is set to the joint position for treatment. However, the existing treatment head is heavy, and medical staff will consume a lot of physical strength and energy in the process of placing and repeatedly adjusting the covering position of the U-shaped magnetic therapy head to accurately cover different affected parts.

[0004] Therefore, there is a need for a pulse magnetic therapy device that can quickly and effectively place a treatment head on an affected area, and the pulse magnetic therapy device is specifically a self-service magnetic therapy device. Summary of the invention

[0005] In order to overcome the problem of the inconvenience of placement and positioning of the current U-shaped magnetic therapy head during use, it is expected to set up a mobile device for carrying the treatment head. By moving the device to the patient's position and simply adjusting the body position, the treatment head can be set to the structure of the affected part. Specifically, by connecting the U-shaped magnetic therapy head with a retractable structure, the horizontal height range that the U-shaped magnetic therapy head can be in is limited; and then by connecting the retractable structure with a track, the horizontal position of the U-shaped magnetic therapy head when the height is fixed is further limited, thereby effectively limiting the movement path of the U-shaped magnetic therapy head in the treatment channel; at the same time, by setting a support platform below the U-shaped magnetic therapy head and corresponding to the position of the slide rail, the U-shaped magnetic therapy head will inevitably cover the patient's limbs on the support platform when it falls. Finally, through the setting of this device, the U-shaped magnetic therapy head can be very conveniently moved to the patient's position, and the patient's joints can be set to the support platform. After adjusting the horizontal position of the U-shaped magnetic therapy head, it will directly fall to the affected part. It is very simple and convenient to use. Specifically, the present invention adopts the following technical solutions: A self-service magnetic therapy device, comprising: A support frame is movable, and the support frame includes a lower support portion and an upper support portion connected thereto; A U-shaped magnetic therapy head, arranged on the upper support portion, the U-shaped magnetic therapy head can change position between the lower support portion and the upper support portion in both horizontal and vertical directions; A support platform, arranged on the lower support portion, capable of changing its position in a vertical direction; After the U-shaped magnetic therapy head is adjusted in the horizontal and vertical directions, the U-shaped magnetic therapy head can be placed above the support platform after the vertical adjustment, and a treatment channel is formed between the U-shaped magnetic therapy head and the support platform.

[0006] Furthermore, a connection structure for connecting the lower support portion and the upper support portion is provided only on one side thereof.

[0007] Through the above-mentioned arrangement, the magnetic therapy machine can be moved to the vicinity of the patient, and the patient's limbs can be sent to the support table through the hollow space without a connecting structure. The vertical height of the support table is then adjusted to allow the patient to maintain an optimal and comfortable placement position. The horizontal position of the U-shaped magnetic therapy head is then adjusted to above the patient's affected area. Finally, the U-shaped magnetic therapy head is moved downward to cover the affected area. The affected area is set between the U-shaped magnetic therapy head and the support table to form a treatment channel for treatment.

[0008] Furthermore, the symmetry plane of the U-shaped magnetic therapy head is always in the same plane as the symmetry plane of the support platform; this arrangement allows the U-shaped magnetic therapy head to be placed above the support platform by moving in only two directions, making adjustment simple and convenient. Furthermore, a positioning groove for placing the patient's limb is provided on the support platform, and the symmetry plane of the positioning groove is the same as the symmetry plane of the support platform.

[0009] Furthermore, the upper support portion includes a sliding rail and a telescopic portion 1 that are slidably connected, the end of the telescopic portion 1 that faces away from the sliding rail is connected to the U-shaped magnetic therapy head, the movement direction of the telescopic portion 1 along the sliding rail is parallel to the axial direction of the treatment channel, and when the length of the telescopic portion 1 is fixed, the sliding rail limits the radial movement of the U-shaped magnetic therapy head in the treatment channel to maintain the continuous existence of the treatment channel. The telescopic portion 1 provides the U-shaped magnetic therapy head with the freedom to move along the central axis of the telescopic portion 1, and the sliding rail provides the U-shaped magnetic therapy head with the freedom to move along the central axis of the treatment channel. When the U-shaped magnetic therapy head moves to the top of the support table to construct a treatment channel, the movement of the U-shaped magnetic therapy head along the central axis of the telescopic portion 1 that continues to approach the lower support portion is limited by the positive pressure between the support table, and the movement of the U-shaped magnetic therapy head along the central axis of the treatment channel is limited by the friction between the support table.

[0010] Furthermore, the telescopic part 1 is a lockable gas spring. When the U-shaped magnetic therapy head overcomes gravity and moves toward the slide rail under the drive of an external force, the axial length of the telescopic part 1 is shortened; when the U-shaped magnetic therapy head is not subjected to an external force, the telescopic part 1 maintains its own axial length. When the medical staff moves the U-shaped magnetic therapy head in the axial direction of the telescopic part 1, it can stop at any height within the travel range by breaking away from the contact with the U-shaped magnetic therapy head. Therefore, the medical staff can first raise the U-shaped magnetic therapy head, and after the patient places the limb at the top of the support platform at a position corresponding to the U-shaped magnetic therapy head, the U-shaped magnetic therapy head can be driven downward to connect with the support platform.

[0011] Furthermore, the end of the U-shaped magnetic therapy head facing the support table is provided with a fitting cavity, and the inner wall of the fitting cavity is provided with a pulse layer; the end of the support table facing the U-shaped magnetic therapy head is provided with a positioning groove, and when the U-shaped magnetic therapy head moves to a working position, the fitting cavity and the positioning groove are closed and form the treatment channel. Correspondingly, the U-shaped magnetic therapy head and the support table can respectively move to an initial position, and the U-shaped magnetic therapy head does not contact the support table when it is in the initial position. The positioning groove is on the path of the fitting cavity moving along the central axis of the telescopic part one, so when the patient's limb is placed in the positioning groove, the U-shaped magnetic therapy head moving to the working position can directly cover the fitting cavity on the patient's limb to prevent squeezing injury to the patient's limb during the closing process of the fitting cavity and the positioning groove. At the same time, there is no need to adjust the corresponding relationship between the patient's limb position and the U-shaped magnetic therapy head, which is conducive to improving operation efficiency.

[0012] Furthermore, the lower support portion includes a base plate and a load-bearing member, the bottom end of the load-bearing member is connected to the base plate, and the top end of the load-bearing member is connected to the slide rail; the outer wall of the load-bearing member facing away from the U-shaped magnetic therapy head is symmetrically provided with a plurality of connecting bolts and the same number of connecting holes, and the axial direction of the connecting bolts is parallel to the axial direction of the connecting holes; when the connecting bolts and the connecting holes are respectively connected to the connecting holes and connecting bolts of another pulse magnetic therapy machine, the radial movement of the two pulse magnetic therapy machines along the connecting bolts is restricted.

[0013] Furthermore, the outer wall of the load-bearing member facing away from the U-shaped magnetic therapy head is symmetrically provided with grooves and bosses, the bosses are penetrated by a pin hole, and a latch is provided for movement in the pin hole; when two pulse magnetic therapy machines are connected to the connecting hole through a connecting bolt, the grooves and bosses of the two pulse magnetic therapy machines cooperate with each other and the pin holes are aligned and connected; when the latch is simultaneously sleeved in the pin holes of the two pulse magnetic therapy machines, the axial movement of the two pulse magnetic therapy machines along the connecting bolt is restricted.

[0014] Furthermore, a second telescopic portion is provided between the support platform and the bottom plate, and two axial ends of the second telescopic portion are respectively connected to the support platform and the bottom plate.

[0015] Furthermore, the load-bearing member is arranged on one side of the central axis of the treatment channel. When the patient's limb approaches the support platform from the other side of the central axis of the treatment channel and finally falls into the positioning groove on the support platform, the load-bearing member does not hinder the movement of the patient's limb.

[0016] Furthermore, the bottom plate is provided with a plurality of universal wheels, and the universal wheels are evenly distributed on the outer wall of the bottom plate away from the support platform.

[0017] Furthermore, the length of the slide rail is greater than the length of the support platform, the number of telescopic parts 1 arranged on the slide rail is at least one, and each telescopic part 1 is connected to a U-shaped magnetic therapy head.

[0018] Beneficial effects of the present invention: By setting up a U-shaped magnetic therapy head and a telescopic part 1, the movement stroke of the U-shaped magnetic therapy head in the vertical direction can be limited, and the U-shaped magnetic therapy head can be stopped at any height within the stroke. A slide rail and a lower support part supporting the position of the slide rail are also provided. The slide rail is slidably connected to the telescopic part 1, further limiting the movement stroke of the U-shaped magnetic therapy head in the horizontal plane when the vertical height is fixed, thereby effectively limiting the U-shaped magnetic therapy head above the support table, and cooperating with the support table to construct a treatment channel.

[0019] By providing a connection structure for connecting the lower support part and the upper support part only on one side thereof, the limb can be placed very conveniently in an unobstructed space on the side opposite to the connection structure.

[0020] By setting up a support platform with adjustable height and a positioning slot on the support platform, and setting the symmetry plane of the positioning slot to always be in the same plane as the symmetry plane of the U-shaped magnetic therapy head, the optimal comfortable height of the patient's limb can be achieved after the limb is set. Then, the patient only needs to place the limb in the positioning slot on the support platform, and the U-shaped magnetic therapy head can be moved above the support platform by adjusting in two directions.

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below through specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation methods. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] A self-help magnetic therapy device, such as Figure 1-8As shown, it includes: a self-service magnetic therapy device, including a support frame 1, which can move, and the support frame 1 includes a connected lower support part 12 and an upper support part 11, and a connection structure for connecting the lower support part 12 and the upper support part 11 is only set on one side of the lower support part 12 and the upper support part 11; a U-shaped magnetic therapy head 2 is arranged on the upper support part 11, and the U-shaped magnetic therapy head 2 can change its position between the lower support part 12 and the upper support part 11 along both horizontal and vertical directions; a support platform 3 is arranged on the lower support part 12, and can change its position in the vertical direction; after the U-shaped magnetic therapy head 2 is adjusted in the horizontal and vertical directions, the U-shaped magnetic therapy head 2 can be placed above the support platform 3 after the vertical adjustment, and a treatment channel 4 is formed between the U-shaped magnetic therapy head 2 and the support platform 3.

[0024] Furthermore, the symmetry plane of the U-shaped magnetic therapy head 2 is always in the same plane as the symmetry plane of the support platform 3; this arrangement allows the U-shaped magnetic therapy head 2 to be placed above the support platform 3 by moving in only two directions, and the adjustment is simple and convenient. Furthermore, a positioning groove 31 for placing the patient's limb is provided on the support platform 3, and the symmetry plane of the positioning groove 31 is the same as the symmetry plane of the support platform 3.

[0025] In some embodiments of the present application, Figure 1-8 As shown, the upper support part 11 includes a sliding rail 111 and a telescopic part 112 that are slidably connected. The end of the telescopic part 112 that is away from the sliding rail 111 is connected to the U-shaped magnetic therapy head 2, and the movement direction of the telescopic part 112 along the sliding rail 111 is parallel to the axial direction of the treatment channel 4. When the length of the telescopic part 112 is fixed, especially when the U-shaped magnetic therapy head 2 and the support platform 3 form the treatment channel 4 and the patient's limb is placed in the treatment channel 4, the sliding rail 111 limits the movement of the U-shaped magnetic therapy head 2 in the radial direction of the treatment channel 4 to maintain the continuous existence of the treatment channel 4. The telescopic part 112 provides the U-shaped magnetic therapy head 2 with the degree of freedom to move along the central axis of the telescopic part 112, and the sliding rail 111 provides the U-shaped magnetic therapy head 2 with the degree of freedom to move along the central axis of the treatment channel 4. The degree of freedom provided by the sliding rail 111 to the U-shaped magnetic therapy head 2 facilitates medical staff to push the U-shaped magnetic therapy head 2 to move along the patient's limb to adjust the treatment position. When the support platform 3 is in contact with the U-shaped magnetic therapy head 2, the movement of the U-shaped magnetic therapy head 2 along the central axis of the telescopic part 112 to continue approaching the lower support part 12 is limited by the positive pressure between the support platform 3, and the movement of the U-shaped magnetic therapy head 2 along the central axis of the treatment channel 4 is limited by the friction between the support platform 3. In this state, the only direct movement that the U-shaped magnetic therapy head 2 can perform is to move away from the support platform 3 along the central axis of the telescopic part 112, but when the U-shaped magnetic therapy head 2 is out of contact with the support platform 3, the treatment channel 4 does not exist immediately. Therefore, when the treatment channel 4 exists, the spatial position relationship of the U-shaped magnetic therapy head 2 is locked.

[0026] In some embodiments of the present application, Figure 1-8 As shown, the telescopic part 112 is a lockable gas spring. As a prior art, the lockable gas spring can stop at any length on the telescopic stroke. The specific structure of the lockable gas spring is not shown in the attached figure. When the U-shaped magnetic therapy head 2 overcomes gravity and moves toward the slide rail 111 under the drive of an external force, the axial length of the telescopic part 112 is shortened; when the U-shaped magnetic therapy head 2 is not subjected to external force, the telescopic part 112 maintains its own axial length. When the medical staff moves the U-shaped magnetic therapy head 2 in the axial direction of the telescopic part 112, it can stop at any height within the stroke by breaking away from the contact with the U-shaped magnetic therapy head 2. Therefore, the medical staff can first raise the U-shaped magnetic therapy head 2, and after the patient places the limb on the top of the support platform 3 at a position corresponding to the U-shaped magnetic therapy head 2, the U-shaped magnetic therapy head 2 is driven downward to connect with the support platform 3.

[0027] In some embodiments of the present application, Figure 1-8 As shown, the end of the U-shaped magnetic therapy head 2 facing the support platform 3 is provided with a fitting cavity 21, and the inner wall of the fitting cavity 21 is provided with a pulse layer; the end of the support platform 3 facing the U-shaped magnetic therapy head 2 is provided with a positioning groove 31, and when the U-shaped magnetic therapy head 2 moves to a working position, the fitting cavity 21 and the positioning groove 31 are closed to form a treatment channel 4. Correspondingly, the U-shaped magnetic therapy head 2 and the support platform 3 can move to an initial position respectively, and the U-shaped magnetic therapy head 2 does not contact the support platform 3 when it is in the initial position. The positioning groove 31 is on the path of the fitting cavity 21 moving along the central axis of the telescopic part 112, so when the patient's limb is placed in the positioning groove 31, the U-shaped magnetic therapy head 2 moving to the working position can directly cover the fitting cavity 21 on the patient's limb, preventing the fitting cavity 21 and the positioning groove 31 from causing squeezing injury to the patient's limb during the closing process, and at the same time, there is no need to adjust the corresponding relationship between the patient's limb position and the U-shaped magnetic therapy head 2, which is conducive to improving the operation efficiency. The U-shaped magnetic therapy head 2 releases low-frequency pulses to the patient's limbs through the fitting cavity 21, thereby assisting in the treatment of osteoporosis, fracture repair, arthritis and other orthopedic diseases. The U-shaped magnetic therapy head 2 is connected to an external instrument through a wire, and medical staff control the start and stop and pulse frequency of the U-shaped magnetic therapy head 2 through the external instrument. The specific structure and working principle of the U-shaped magnetic therapy head 2 and the external instrument connected to the U-shaped magnetic therapy head 2 are not shown as prior art.

[0028] In some embodiments of the present application, Figure 1-8As shown, the lower support portion 12 includes a base plate 121, and a load-bearing member 122 is arranged on the connecting structure. The bottom end of the load-bearing member 122 is connected to the base plate 121, and the top end of the load-bearing member 122 is connected to the slide rail 111. By arranging the load-bearing member 122, the entire structure can be maintained stable, and the entire structure will not be deformed due to the arrangement of the connecting structure only on one side. After the load-bearing member 122 is arranged, the effect of facilitating the arrangement of the affected limb while maintaining the stability of the entire device can be achieved.

[0029] Furthermore, the weight of the bottom plate 121 can be increased, for example, by setting a water tank or a metal block on the bottom plate 121. By increasing the weight of the bottom plate 121, the risk of the entire structure tilting or falling can be avoided, and together with the load-bearing member 122, the risk of tipping due to the unilateral setting of the connecting structure can be solved.

[0030] In some embodiments of the present application, in order to achieve the purpose of treating two limbs or two patients, the load-bearing member 122 is symmetrically provided with a plurality of connecting bolts 1221 and the same number of connecting holes 1222 on the outer wall away from the U-shaped magnetic therapy head 2, and the axial direction of the connecting bolts 1221 is parallel to the axial direction of the connecting holes 1222; when the connecting bolts 1221 and the connecting holes 1222 are respectively connected to the connecting holes 1222 and the connecting bolts 1221 of another pulse magnetic therapy machine, the radial movement of the two pulse magnetic therapy machines along the connecting bolts 1221 is restricted. Figure 1-8 As shown, the outer wall of the load-bearing member 122 facing away from the U-shaped magnetic therapy head 2 is symmetrically provided with a groove 1223 and a boss 1224, and the boss 1224 is penetrated by a pin hole 1225, and a latch 1226 is provided to move in the pin hole 1225; when two pulse magnetic therapy machines are connected to the connecting hole 1222 through the connecting bolt 1221, the grooves 1223 and the boss 1224 of the two pulse magnetic therapy machines cooperate with each other and the pin holes 1225 are aligned and connected; when the latch 1226 is simultaneously sleeved in the pin holes 1225 of the two pulse magnetic therapy machines, the axial movement of the two pulse magnetic therapy machines along the connecting bolt 1221 is restricted. When the axial and radial movements of the two magnetic therapy machines on the connecting bolt 1221 are both restricted, the connection relationship between the two magnetic therapy machines is stable. This arrangement can well achieve the purpose of multi-limb treatment. Furthermore, the connecting structure is arranged between the lower support part 12 and the upper support part 11, and its width is half of the width of the base plate 121. This arrangement allows the operator to observe two affected limbs at the same time, especially when treating two affected limbs of the same patient.

[0031] In some embodiments of the present application, Figure 1-8As shown, a second telescopic part 32 is provided between the support platform 3 and the bottom plate 121. The two axial ends of the second telescopic part 32 are respectively connected to the support platform 3 and the bottom plate 121. The second telescopic part 32 is specifically a hydraulic telescopic rod, and the axial distance between the two ends of the hydraulic telescopic rod can be adjusted. As a prior art, its specific structure is not shown in the drawing part.

[0032] During use, as Figure 1-8 shown, since the load-bearing member 122 is arranged on one side of the central axis of the treatment channel 4. During the process that the patient's limb approaches the support platform 3 from the other side of the central axis of the treatment channel 4 and finally falls into the positioning groove 31 on the support platform 3, the load-bearing member 122 does not obstruct the movement of the patient's limb. When two pulse therapy machines are connected through the load-bearing member 122, the patient can place the limbs on both sides of the connected load-bearing member 122 without any obstruction on the support platform 3 in the initial position, lift the patient's limb to an appropriate height by adjusting the axial length of the second telescopic part 32, and finally lower the U-shaped magnetic therapy head 2 so that the positioning groove 31 and the fitting cavity 21 surround the treatment position of the patient's limb.

[0033] In some embodiments of the present application, as Figure 1-8 shown, the bottom plate 121 is provided with a plurality of universal wheels 1211. The universal wheels 1211 are evenly distributed on the outer wall of the bottom plate 121 facing away from the support platform 3. Medical staff can flexibly move the pulsed magnetic therapy device in the treatment environment based on the setting of the universal wheels 1211.

[0034] In some embodiments of the present application, in order to meet the magnetic therapy treatment of multiple affected parts of a single affected limb, a plurality of U-shaped magnetic therapy heads 2 moving along the slide rail 111 can be arranged on the slide rail 111; as Figure 1-8 shown, the length of the slide rail 111 is greater than the length of the support platform 3. The number of the first telescopic parts 112 arranged on the slide rail 111 is at least one. The end of the first telescopic part 112 facing the upper support part 11 is connected with a slider 1121 and is slidably connected to the slide rail 111 through the slider 1121. Medical staff can place one or more first telescopic parts 112 into the slide rail 111 through the slider 1121 according to actual treatment needs. Each first telescopic part 112 is connected to a U-shaped magnetic therapy head 2. When two adjacent U-shaped magnetic therapy heads 2 move along the slide rail 111 and contact, the fitting cavities 21 of the two U-shaped magnetic therapy heads 2 are communicated and can completely cover the limb. This setting can meet the simultaneous treatment of multiple affected parts of a single limb.
