Description

Technical Field

[0001] This invention relates to the field of rehabilitation and physiotherapy equipment technology, specifically to a heated glove for treating osteoarthritis patients based on a pulsed electromagnetic field. Background Technology

[0002] As an important component of rehabilitation therapy, hand osteoarthritis assistive treatment devices are widely used in daily heat therapy relief, home rehabilitation, and hand joint warming care for osteoarthritis patients. When finger joints are in pain, stiffness, and limited mobility, there are high requirements for the location, fit, and comfort of the heat therapy application.

[0003] In existing technologies, such as AOBOCO's "Heated Gloves for Arthritis Hands," a glove-like covering structure is used. When in use, hands are inserted into the heated gloves, and the built-in heating unit provides overall heating to the palms, fingers, and wrists. Continuous heat therapy can be achieved through temperature and timer controls. These products typically cover multiple joints on the hands with a large, fixed heating area to relieve stiffness, promote local circulation, and improve hand discomfort. Their core function is to provide wearable, comprehensive heat therapy for the hands and joints, meeting the daily heat therapy needs of osteoarthritis and similar hand discomfort.

[0004] However, in actual use of the aforementioned heated gloves, because their heating areas are usually fixed and covered, it is difficult to ensure that multiple heating points fit well with the corresponding finger joints while maintaining a comfortable hand position, especially when there are differences in the degree of finger flexion, stiffness, or joint position. This limits the targeted heating effect on the joints. Furthermore, when multiple segmented heat therapies are required, these products typically require continuous wear with frequent heating cycles or repositioning, making it difficult to achieve simultaneous contact and disengagement of heating points on multiple joints. This affects the adaptability to different patients' finger conditions and the convenience of multi-joint cyclic heating. Therefore, it is necessary to propose a heated glove for osteoarthritis patients based on pulsed electromagnetic fields to solve these problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a heated glove for treating osteoarthritis patients based on a pulsed electromagnetic field. This glove uses a transmission component to simultaneously push multiple heating elements towards the finger joints, allowing patients to receive multiple segmented heating treatments as needed without repeated removal and re-wearing. Furthermore, it allows the heating elements to be promptly moved away from the joints during treatment breaks, thus resolving the problem of existing treatment gloves failing to simultaneously accommodate the different finger conditions of patients and provide convenient, cyclical heating for multiple joints.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A heated glove for treating osteoarthritis patients based on pulsed electromagnetic fields, comprising a glove body, wherein the finger portion of the glove body is provided with a plurality of heating components for heating the finger joints, and a transmission component is provided between the heating components for synchronously driving the heating components to move under conditions that adapt to finger bending. The top of the finger portion of the glove body is provided with a driving component for synchronously driving the transmission component to move. The driving component includes a trapezoidal plate, and a fixing block is fixedly connected to the top of the finger portion of the glove body. The fixing block has a through groove, and symmetrically arranged trapezoidal sliders are slidably fitted in the through groove along the direction of the through groove. The side walls of the trapezoidal sliders that are close to each other have sliding grooves, and the trapezoidal plate and its adjacent sliding groove are slidably fitted. A transmission rod is fixedly connected to the side wall of each trapezoidal slider, and the other end of the transmission rod is rotatably fitted with the transmission component. A spring is provided between the side walls of adjacent transmission rods that are close to each other. The top of the back of the glove body is provided with a power component for synchronously pulling all the trapezoidal plates.

[0007] The technical principles of the above solution are as follows: After the patient puts on the glove, their fingers can initially remain in a naturally bent or comfortable position. At this time, the heating components, in coordination with the transmission and drive components, are positioned away from the joints and do not continuously press against the fingers. Because the transmission component adapts to finger bending, each finger, regardless of its degree of bending, can still drive the corresponding heating component to maintain a movement relationship matching the joint position. When treatment is needed, the drive component synchronously pulls the drive components at each finger location, which in turn drives the transmission component, causing multiple heating components to simultaneously approach and adhere to the corresponding finger joints for concentrated heating of multiple joint areas. When treatment is paused, the drive component loses its tension, and under the reset action of the spring, it drives the transmission component to move in the opposite direction, causing multiple heating components to simultaneously move away from the joints. Thus, the patient can repeatedly perform cyclical treatments of applying heat and removing the glove as needed without removing the glove.

[0008] The above approach has the following beneficial effects: 1. This invention uses a transmission component to simultaneously push multiple heating components toward the joints under conditions that are adapted to the bending state of the fingers. This allows different patients to achieve simultaneous heating of multiple joints while maintaining a relatively comfortable finger posture, even if there are differences in the degree of finger bending and stiffness. This improves the adaptability of the device to different finger states and the targeted nature of the treatment.

[0009] 2. This invention uses a power component to synchronously drive the heating components of multiple fingers to move closer to or further away from the joints, so that patients can start multi-joint heating treatment as needed without repeatedly taking off the glove or adjusting each finger individually after wearing the glove. The pressure is also released synchronously during the pause phase, thereby improving the convenience of segmented cyclical treatment.

[0010] 3. When treatment is paused, the present invention can use a spring to drive the transmission component to reset, so that multiple heating components can move away from the finger joints at the same time. This not only helps to reduce the local pressure and stuffiness caused by the continuous contact of the heating components, but also makes it easy to switch between treatment and rest states multiple times during the same wearing process, thereby improving the overall comfort of use.

[0011] Furthermore, the heating assembly includes a controller and several positioning rods. One end of each positioning rod is fixedly connected to the side wall of the finger part of the glove body. Each positioning rod is slidably fitted with a pressure plate. Each pressure plate has a metal coil embedded in it. A heating film is fixedly connected to one side wall of each pressure plate. The other side wall of each pressure plate is fixedly connected to its adjacent transmission assembly. The heating film and the metal coil are electrically connected to the controller.

[0012] Beneficial effects: The positioning rod guides the pressure plate, ensuring a stable movement direction and reducing deviation as it approaches the joint. Simultaneously, integrating the heating film and metal coil into the pressure plate facilitates simultaneous local heating and pulsed electromagnetic field therapy as the plate approaches the joint, improving the integration and stability of the treatment components at a single joint. The metal coil, driven by a controller, generates a pulsed electromagnetic field with a frequency of 10-30Hz, which works synergistically with the heat field generated by the heating film on the finger joint. This heat therapy promotes local blood circulation, while the pulsed electromagnetic field inhibits inflammation and relieves pain.

[0013] This invention integrates a metal coil and a heating film onto the same pressure plate, which is synchronously driven by a transmission component to adhere to the joint. Compared to existing pulsed electromagnetic field therapy devices that require the patient to maintain a fixed posture, this solution can continuously provide stable pulsed electromagnetic field stimulation while the patient's fingers are in natural movement, achieving a synergistic effect of thermotherapy and magnetotherapy, and enhancing anti-inflammatory and analgesic effects.

[0014] Furthermore, the transmission assembly includes a second rotating shaft that is rotatably engaged with the end of the transmission rod away from the trapezoidal slider. The second rotating shaft is fixedly connected to a second rotating rod, and the other end of the second rotating rod is rotatably engaged with a first rotating shaft. The first rotating shaft is fixedly connected to a first rotating rod, and the second rotating shaft is rotatably engaged with a third rotating rod. The other end of the third rotating rod is fixedly connected to a third rotating shaft. The positioning rods coaxially pass through the adjacent first rotating shaft, second rotating shaft, and third rotating shaft, as well as the end of the first rotating rod away from the first rotating shaft, and are all slidably engaged with them. One side wall of the first rotating shaft, second rotating shaft, and third rotating shaft is fixedly connected to the adjacent pressure plate.

[0015] Beneficial effects: The transmission components can correspond to the movement of the distal, middle and proximal segments of the finger, allowing the pressure plate to move as a whole with the joint position even when the finger is bent, thereby improving the adaptability to different finger postures and the accuracy of joint correspondence.

[0016] Furthermore, the finger section sidewalls of the glove body are provided with locking components for locking the first, second, and third rotating shafts. The locking components include locking blocks that are fixedly connected to the side of the pressure plate, and several half-tooth rings that are fixedly connected to the finger section sidewalls of the glove body. The locking blocks engage with their adjacent half-tooth rings.

[0017] Beneficial effects: By cooperating with the locking block and the semi-tooth ring, the first, second and third rotation axes can be restricted after the pressure plate is close to the joint, so that the corresponding joints can maintain a more stable posture during treatment. This not only helps to reduce painful movement of the diseased joint, but also reduces the displacement of the pressure plate and treatment piece relative to the joint, thus improving the stability of the treatment process.

[0018] Furthermore, the power assembly includes an automatic reel fixedly connected to the back of the glove body. The automatic reel is fixedly connected to several traction ropes, the other end of which is fixedly connected to an adjacent trapezoidal plate. The automatic reel is electrically connected to the controller.

[0019] Beneficial effects: By centrally winding multiple traction ropes with an automatic reel, the trapezoidal plate movements of each finger can be pulled simultaneously at one time, avoiding the tedious operation caused by adjusting each finger individually. This allows multiple joint positions to enter the treatment state more quickly and facilitates the controller to uniformly coordinate the start and stop of the automatic reel, heating film, and metal coil.

[0020] Furthermore, each traction rope is equipped with a guide wheel that rotates, and the axle of the guide wheel is perpendicular to the top of the glove body and is fixedly connected to the glove body.

[0021] Beneficial effects: By setting guide wheels on the traction rope path, the traction force output by the automatic reel can be converted into a tension force that is more suitable for the direction of force on the trapezoidal plate, reducing the skewing and friction jamming caused when the traction rope is pulled directly, making the trapezoidal plate move more smoothly, and thus improving the consistency of each pressure plate when it approaches the joint synchronously.

[0022] Furthermore, the positioning rods are all located on the side wall of the finger part of the glove body, corresponding to the finger joints.

[0023] Beneficial effects: By setting the positioning rod at the position corresponding to the finger joint, the movement path of the pressure plate can directly correspond to the distal interphalangeal joint, proximal interphalangeal joint, and metacarpophalangeal joint area, reducing the possibility of the pressure plate deviating from the treatment target area. This makes it easier for the heating film and metal coil to concentrate their effect on the joint when they are close, thus improving the local treatment targeting.

[0024] Furthermore, a limit plate is fixedly connected to the end of the positioning rod away from the glove body.

[0025] Beneficial effects: By setting a limiting plate at the end of the positioning rod away from the glove body, the risk of the pressure plate, rotating shaft and rotating rod coming off when sliding back and forth along the positioning rod can be limited, so that the transmission components can maintain a stable connection during repeated tightening and resetting, thereby improving the reliability and safety of the whole structure.

[0026] Furthermore, a heating ring is fixedly connected to the part of the glove body near the wrist.

[0027] Beneficial effects: By adding a heating ring to the wrist area, heat therapy can be applied to the wrist joint while simultaneously heating the finger joints. It also provides auxiliary insulation, reducing heat loss caused by cold air entering the glove body through the wrist area. This helps maintain the overall warmth of the hand, thereby improving comfort and the continuous treatment experience during wear.

[0028] Furthermore, the area where the glove body and the pressure plate are in contact is made of a thermally conductive and insulating silicone layer.

[0029] Beneficial effects: By setting the area where the glove body and the pressure plate are in contact with a thermally conductive and insulating silicone layer, it is not only beneficial for the transfer of heat from the pressure plate side to the finger joints, but also improves the contact flexibility when the pressure plate is close, reducing the discomfort caused by hard pressure. At the same time, the non-metallic insulating material also helps to reduce the impact on the working state of the metal coil. Attached Figure Description

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

Therefore, they should not be construed as limitations on the invention.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] The following detailed description illustrates the specific implementation method: Example 1:

[0039] As attached Figure 1 and Figure 2 As shown: A heated glove for treating osteoarthritis patients based on pulsed electromagnetic fields includes a glove body 1. The finger section sidewalls of the glove body 1 are provided with a plurality of heating components for heating the finger joints. A transmission component is provided between the heating components for synchronously driving the heating components to move under the condition of adapting to finger bending. The top of the finger section of the glove body 1 is provided with a drive component for synchronously driving the transmission component to move.

[0040] like Figure 1 and Figure 3As shown, the drive assembly includes a trapezoidal plate 5, a fixing block 2 is glued to the top of the finger part of the glove body 1, the fixing block 2 has a through groove 3, and symmetrically arranged trapezoidal sliders 4 are slidably engaged in the through groove 3 along the direction of the through groove 3. The side walls of the trapezoidal sliders 4 that are close to each other have sliding grooves 6, and the trapezoidal plate 5 and its adjacent sliding grooves 6 are slidably engaged. The side walls of the trapezoidal sliders 4 are bolted with transmission rods 7, and the other end of the transmission rods 7 is rotatably engaged with the transmission assembly. A spring 22 is provided between the side walls of adjacent transmission rods 7 that are close to each other.

[0041] Specifically, when the trapezoidal plate 5 is pulled along the side away from the transmission rod 7 under the action of external force, the two sides of the trapezoidal plate 5 and the adjacent slide groove 6 continue to maintain sliding engagement. Since the trapezoidal plate 5 and the slide groove 6 form an inclined guiding relationship, the movement of the trapezoidal plate 5 will generate opposing component forces on the two trapezoidal sliders 4, causing the two trapezoidal sliders 4 to slide along the through groove 3 in a direction closer to each other, thereby driving the two transmission rods 7 fixed on the side wall of the trapezoidal slider 4 to move synchronously towards each other; when the trapezoidal plate 5 loses its tension, the spring 22 set between the adjacent transmission rods 7 rebounds, pushes the two transmission rods 7 apart again, and drives the trapezoidal sliders 4 to reset along the through groove 3.

[0042] The heating assembly includes a controller and several positioning rods 14. One end of each positioning rod 14 is bonded to the side wall of the finger part of the glove body 1. Each positioning rod 14 is located on the side wall of the finger part of the glove body 1 at a position corresponding to the finger joint. Each positioning rod 14 is coaxially slidably fitted with a pressure plate 11. Each positioning rod 14 is bonded to a limit plate 15 at the end away from the glove body 1.

[0043] Each pressure plate 11 has a metal coil embedded in it. A heating film is glued to one side wall of each pressure plate 11. The other side wall of each pressure plate 11 is bolted to its adjacent transmission component. The heating film and the metal coil are electrically connected to the controller.

[0044] Specifically, in this embodiment, taking the index finger as an example, three positioning rods 14 are provided on each of the left and right sides of the index finger, and three pressure plates 11 are distributed along the positioning rods 14, corresponding to the distal interphalangeal joint, proximal interphalangeal joint and metacarpophalangeal joint respectively, with the pressure plates 11 on the left and right sides facing each other.

[0045] Since a heating film is fixed on the side of the pressure plate 11 facing the index finger, and a metal coil is embedded inside the pressure plate 11, the heating film and the metal coil are opened and closed by the controller. When the pressure plate 11 moves closer to the side of the index finger joint under the subsequent transmission action, the heating film can be closer to the joint to transfer heat, and the metal coil also moves closer to the diseased joint with the pressure plate 11, so that heating and pulsed electromagnetic field therapy can be carried out synchronously under the control of the controller.

[0046] After the controller synchronously activates the heating film and metal coil, the heating film generates a localized thermal field of 40-45℃, promoting blood circulation around the joint and relieving stiffness. Simultaneously, the metal coil, driven by the controller, generates a pulsed electromagnetic field with a frequency of 10-30Hz and a magnetic field strength of 5-15mT. This pulsed electromagnetic field can penetrate tissue and act on the synovium and chondrocytes through electromagnetic induction, promoting the binding of calcium ions and calmodulin, thereby inhibiting the inflammatory response and relieving pain at the molecular level. The synergistic effect of thermotherapy and magnetotherapy can exert therapeutic effects at both the physical and molecular levels.

[0047] Since the thumb has fewer joints than the other four fingers, one less pressure plate 11 and positioning rod 14 can be used, and the overall working principle is the same as that of the index finger.

[0048] like Figure 1 and Figure 2 As shown, the transmission assembly includes a second rotating shaft 9 that is rotatably engaged with the end of the transmission rod 7 away from the trapezoidal slider 4. A second rotating rod 19 is welded to the second rotating shaft 9. A first rotating shaft 8 is rotatably engaged with the other end of the second rotating rod 19. A first rotating rod 18 is welded to the first rotating shaft 8. A third rotating rod 20 is rotatably engaged with the second rotating shaft 9. A third rotating shaft 10 is welded to the other end of the third rotating rod 20. The positioning rods 14 coaxially pass through the adjacent first rotating shaft 8, second rotating shaft 9, and third rotating shaft 10, as well as the end of the first rotating rod 18 away from the first rotating shaft 8, and are all slidably engaged with them. One side wall of the first rotating shaft 8, second rotating shaft 9, and third rotating shaft 10 is bolted to the adjacent pressure plate 11.

[0049] Specifically, taking the index finger as an example, the first pivot 8 corresponds to the side of the distal interphalangeal joint, the second pivot 9 corresponds to the side of the proximal interphalangeal joint, and the third pivot 10 corresponds to the side of the metacarpophalangeal joint. The first pivot 18, the second pivot 19, and the third pivot 20 are distributed along the outer sides of the distal phalanx, the middle phalanx, and the proximal phalanx of the index finger, respectively.

[0050] When the index finger is naturally bent, each phalanx drives the first rotating rod 18, the second rotating rod 19, and the third rotating rod 20 to move, which in turn drives the first rotating shaft 8, the second rotating shaft 9, and the third rotating shaft 10 to rotate, so that the transmission assembly can move in accordance with the current bending posture of the index finger. At the same time, the first rotating shaft 8, the second rotating shaft 9, the third rotating shaft 10, and the end of the first rotating rod 18 are all slidably engaged with the positioning rod 14, so that while adapting to the bending of the finger, the entire assembly can move along the positioning rod 14 toward or away from the side of the index finger, leaving a travel space for the pressure plate 11 to approach the joint. During treatment, the entire assembly moves along the positioning rod 14 toward the side of the index finger and drives the pressure plate 11 to approach its adjacent joints. When treatment is stopped, the assembly moves away.

[0051] like Figure 1 and Figure 2As shown, the finger section sidewalls of the glove body 1 are provided with locking components for locking the first rotating shaft 8, the second rotating shaft 9 and the third rotating shaft 10.

[0052] The locking assembly includes a locking block 12 integrally formed on the side of the pressure plate 11, and several half-tooth rings 13 are glued to the side wall of the finger part of the glove body 1, and the locking block 12 engages with its adjacent half-tooth ring 13.

[0053] Specifically, in the initial state, when the pressure plate 11 is away from the side wall of the finger, the locking block 12 is not engaged with the semi-gear ring 13. When the pressure plate 11 moves towards the side of the index finger along the positioning rod 14 under the drive of the transmission component, the locking block 12 on the side of the pressure plate 11 will gradually enter the tooth groove range of its adjacent semi-gear ring 13 and form an effective engagement. At this time, the rotation of the first rotating shaft 8, the second rotating shaft 9, and the third rotating shaft 10 is restricted, and the first rotating rod 18, the second rotating rod 19, and the third rotating rod 20 no longer follow the large swing of the index finger's phalanges, thereby forming a limiting support for the distal interphalangeal joint, the proximal interphalangeal joint, and the metacarpophalangeal joint. Conversely, when the transmission component drives the pressure plate 11 to move away from the side of the index finger along the positioning rod 14, the locking block 12 exits the effective engagement range of the semi-gear ring 13, the segmented skeleton returns to a movable state, and the index finger can bend again.

[0054] like Figure 4 As shown, the top of the back of the glove body 1 is equipped with a power component for synchronously pulling all the trapezoidal plates 5.

[0055] The power assembly includes an automatic winder 16 bonded to the back of the glove body 1. The automatic winder 16 is bonded with several traction ropes 17. The other end of each traction rope 17 is bonded to an adjacent trapezoidal plate 5. The automatic winder 16 is electrically connected to a controller. Each traction rope 17 is rotatably fitted with a guide wheel 21. The axle of each guide wheel 21 is perpendicular to the top of the glove body 1 and bonded to the glove body 1.

[0056] Specifically, after the patient puts on the glove body 1, they can first adjust their fingers to a more comfortable bent position. At this time, the automatic winding device 16 is not wound up, the traction rope 17 is in a relaxed or slightly tensioned state, the trapezoidal slider 4 and the transmission rod 7 are kept open under the action of the spring 22, and there is a gap between the pressure plate 11 and the side of the finger, so the finger can move freely.

[0057] During treatment, the controller activates the automatic winding device 16 to simultaneously wind up all the traction ropes 17. After being turned by the guide wheel 21, the traction ropes 17 pull each trapezoidal plate 5 in a more stable direction, causing the transmission rods 7 on both sides to drive the transmission components and the pressure plate 11 to move along the positioning rod 14 towards the side of the finger joint. After the pressure plate 11 is close to the joint, the heating film and the metal coil simultaneously approach the affected joint, and the locking block 12 and the half-tooth ring 13 form an effective engagement, limiting and supporting the corresponding finger joint. Subsequently, the controller simultaneously activates the heating film and the metal coil to perform treatment. After the treatment, the automatic winding device 16 releases the rope, the spring 22 pushes the trapezoidal slider 4 and the transmission rod 7 to reset, the pressure plate 11 retracts from the joint, the locking block 12 exits the effective engagement range, and the finger returns to a state of free movement.

[0058] In this embodiment, the automatic winding device 16 drives the drive assembly and transmission assembly to synchronously drive the pressure plates 11 on the sides of each finger toward the joint, so that the heating film and metal coil can stably adhere to the joint when the finger is in a comfortable position. During treatment, the locking assembly provides limiting support to the joint, and the pressure can be released in time after treatment, thus taking into account the local treatment effect, joint stability and wearing comfort.

[0059] Example 2:

[0060] The difference from Embodiment 1 is that a heating ring (not shown in the figure) is attached to the part of the glove body 1 near the wrist, and the area where the glove body 1 and the pressure plate 11 are in contact is made of thermally conductive and insulating silicone layer.

[0061] Specifically, the heating ring located near the wrist of the glove body 1 can provide auxiliary heating around the wrist under the control of the controller, thereby reducing heat loss from the wrist opening. At the same time, after the area where the glove body 1 and the pressure plate 11 are in contact is made of thermally conductive and insulating silicone, the heat generated by the heating film when the pressure plate 11 is close to the fingers is more easily transferred to the side of the joint. In addition, the thermally conductive and insulating silicone layer can buffer the local hardness caused by the pressure plate 11 pressing against the fingers, improve wearing comfort, and reduce the impact on the operation of the metal coil.

[0062] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
