Joint support device with electrode pad unit

Abstract

The present application discloses a joint support device having an electrode pad unit, which can be placed against at least one human joint and can match the human joint in both a bent and unbent state. The device comprises a covering structure, a control device, and at least one electrode pad unit. The covering structure can be worn on the human joint, with the electrode pad unit disposed on its inner side and the control device disposed on its outer side. The control device can transmit current to the electrode pad unit, enabling the electrode pad unit to output current to stimulate and / or heat the muscles. When the human joint moves, the force generated by the covering structure can force the electrode pad unit to adhere tightly to the skin surface. In this way, the electrode pad unit will not become loose due to frequent movement of the human joint.

Description

Technical Field

[0001] The present application relates to the field of joint support devices, and in particular to a joint support device having at least one electrode pad and an inflatable airbag. Background Art

[0002] Traditionally, someone who has injured their knee, ankle, shoulder, elbow, wrist, or back may seek different treatments to reduce the swelling and pain caused by the injury. For example, the patient may need to wear a brace to limit the movement of the injured area, use compression therapy to reduce fluid retention and swelling, or use electrotherapy to relieve pain and stimulate healing.

[0003] However, using different treatment methods can take up a significant amount of time and cause significant inconvenience to patients. Therefore, based on our long-term service in the technical field of this application and our continued focus on the development of related technologies, we have drawn attention to the following areas of improvement in conventional physical therapy devices, which have not only attracted our attention but have also been addressed in this application. The improvements in conventional physical therapy devices are described below.

[0004] First, traditional physical therapy devices such as body joint support equipment often have large dimensions and must be placed in a fixed location, so they are not very convenient to use. Secondly, when a user is alone, it is difficult to accurately stick the electrodes on the body joint support equipment to their own body parts, such as the back of the shoulder, lower back or waist. Furthermore, traditional electrodes are only adhered to the skin by colloid, without any other fixing means or mechanism. Therefore, when the patient is in a state of exercise, as the patient's limb movements are frequent or excessive, it is very easy for the surface of the traditional electrode to become inconsistent with the patient's skin, or even for the traditional electrode to fall off. Moreover, when the traditional electrode is not completely attached to the human skin, it will cause poor conduction, which will not only make the patient feel acupuncture pain, but also lose the therapeutic effect. Finally, when the traditional electrode is attached to the human body's waist, ankles, knees, elbows, shoulders and other joints, it is difficult for the traditional electrode to adhere completely, and it is even very likely to fall off. The main reason is that the skin at the aforementioned joints changes position greatly during physical activities and is more prone to violent shaking. For example, when traditional electrodes are attached to the ankles, walking or running will cause the skin at the corresponding ankles to frequently stretch and contract, making it easy for the traditional electrodes to fall off the ankle skin.

[0005] In summary, patients currently spend a lot of time and money seeking different treatment methods, and conventional physical therapy devices are unable to meet the needs of the above users. Therefore, this application aims to effectively solve the above problems and provide users with a more convenient joint support device. Summary of the Invention

[0048] The following embodiments will further illustrate the relevant technical contents of this application in detail, but the disclosed contents are not intended to limit the scope of protection of this application.

[0049] The present application relates to a joint support device with an electrode pad unit. In a first embodiment, as shown in Figures 1 to 3 , the joint support device E includes a covering structure 1 that can be placed against or against at least one human joint and configured to accommodate the joint in both a flexed and unflexed state. The covering structure 1 can be secured to the joint via at least one adjustment strap 15 and / or the covering structure's own elasticity. Because the covering structure 1 applies pressure to the joint, it can support and assist in maintaining one or more joints in a stable static position, for example, by maintaining a user's elbow in a stable flexed position. Furthermore, the covering structure 1 can better support and assist in maintaining the joint within a limited range during movement. For example, the covering structure 1 can prevent the user's feet from excessively turning outward when walking (i.e., preventing them from walking with their feet splayed out). Furthermore, the elasticity of the covering structure 1 can be used to apply a restoring force to the joints of the human body when the user is moving (e.g., walking), thereby supporting and helping the joints return to their natural and normal range of motion. For example, when the user walks, the sole of the foot bends, and the covering structure 1 bends with it. At this time, the restoring force of the covering structure 1 will restore the foot to a non-bent state, thereby supporting and helping the sole of the foot return to a nearly straight (equivalent to horizontal) state. The inner side of the covering structure 1 or one of its covering bodies 11 refers to the surface of the skin that faces the joint when the joint support device E is applied to the joint; the outer side of the covering structure 1 or the covering body 11 refers to the surface of the skin that faces away from the joint when the joint support device E is applied to the joint.

[0050] Please refer to Figures 1 to 3. In some embodiments, the joint support device E can include a covering structure 1, at least one electrode pad unit 2 and a control device 3, wherein the covering structure 1 can be worn and covered on the joints of the human body, such as: waist, ankles, knees, elbows, shoulders, etc., and the force generated by itself can make its inner side stick to the skin surface of the human joint.

[0051] Referring again to FIG. 2 , the covering structure 1 includes a covering body 11 , at least one airbag 13 , at least one inflatable device 14 , and at least one adjustment strap 15 ( FIG. 2 is an embodiment in which two adjustment straps 15 are provided). The covering body 11 is composed of at least a first sheet 111 and a second sheet 112 , but the present invention is not limited thereto. In other embodiments of the present application, the airbag 13 can be omitted. Instead, the inner side of the covering body 11 is tightly pressed against the skin surface at the human joint by the tension and pressure generated when the two adjustment straps 15 are tightened and fixed to the second sheet 112 . In some embodiments, the covering body 11 can be a single sheet or composed of three or more layers. The inner surfaces of the first sheet 111 and the second sheet 112 mentioned herein refer to surfaces facing each other when the first sheet 111 and the second sheet 112 are assembled; the outer surfaces of the first sheet 111 and the second sheet 112 mentioned herein refer to surfaces facing away from each other when the first sheet 111 and the second sheet 112 are assembled.

[0052] As described above, the covering body 11 is flexible or elastic and can be bent to cover and / or wrap around at least one human joint, such as the user's knee. The outer surface of the first sheet 111 can serve as the inner surface of the covering body 11. In some embodiments, the first sheet 111 can include a first material, or can be made entirely of the first material, or the outer surface of the first sheet 111 can be covered by the first material. The first material can be a fabric or a material with fabric characteristics to provide better skin comfort when placed against the skin. The outer surface of the second sheet 112 can serve as the outer surface of the covering body 11. The second material can be made of a second material with a higher hardness than the first material, such as a plastic material, to provide greater structural strength than the first sheet 111. In some embodiments, at least one additional component or film layer (e.g., a waterproof layer) can be added to the outer surface of the second sheet 112 based on actual product requirements. The first and second sheets 11 and 112 can be integrally connected by adhesive or other fixing means along their entire or partial peripheries. The unsealed portions between the first and second sheets 11 and 112 define a space for accommodating the components of the joint support device E. Referring again to Figures 1 to 3 , in some embodiments, the airbag 13 can be located between the first and second sheets 111 and 112 (i.e., within the covering body 11 ). When inflated, the airbag 13 can expand toward the inner side of the covering body 11 . For example, when the covering body 11 is wrapped around a user's knee and the airbag 13 expands along the inner side, the force generated by the airbag 13 causes the first sheet 111 (i.e., the inner side of the covering body 11 ) to press against the skin surface of the knee, allowing the first sheet 111 to adhere to the skin surface. Furthermore, the inflator 14 can be connected to the airbag 13 .

[0053] Referring to Figures 1, 2, 5, and 6, in some embodiments, the inflation device 14 includes an inflation portion 140 and an air valve 141. The air valve 141 is in communication with the airbag 13 and can be fixed to the covering structure 1. The inflation portion 140 can be a manual inflation pump, but is not limited thereto. In other embodiments of the present application, the inflation portion 140 can also be an electric inflation pump. Furthermore, the inflation portion 140 can be directly connected to the air valve 141, so that the inflation portion 140 can inflate or deflate the airbag 13, thereby changing the expanded or deflated size of the airbag 13. In some embodiments, the air valve 141 is provided with a spring and an opening and closing mechanism driven by the spring. When the inflatable portion 140 is connected to the air valve 141, it compresses the spring to open the opening and closing mechanism, causing the inflatable valve 141 to be in an open state, allowing the inflatable portion 140 to inflate the airbag 13. When the inflatable portion 140 is separated from the air valve 141, the spring is released and returns to its original uncompressed state, locking the opening and closing mechanism and causing the inflatable valve 141 to be closed. However, the present application is not limited to this. In other embodiments, the inflatable device 14 may further include at least one tube, one end of which may be connected to the air valve 141 or pass through the second plate 112 to connect to the airbag 13, and the other end of which may be connected to the inflatable portion 140, so that the inflatable portion 140 can inflate or deflate the airbag 13 to change the degree of expansion or deflation of the airbag 13. After inflation is completed, the tube can be removed from the air valve 141 , that is, the covering structure 1 only has the air valve 141 but no tube, so that the user will not be disturbed by the tube or the inflatable portion 140 during exercise.

[0054] Referring again to FIG. 6 , in some embodiments, the inflator 14 may further include a switching assembly 144 for switching the air valve 141. When the air valve 141 does not have the aforementioned spring-driven opening and closing mechanism, the switching assembly 144 can switch the air valve 141 between an open and a closed state. In other words, the switching assembly 144 can replace the aforementioned spring-driven opening and closing mechanism. In some embodiments, when the air valve 141 has the aforementioned spring-driven opening and closing mechanism, the switching assembly 144 can override or control the spring-driven opening and closing mechanism. When the air valve 141 has the aforementioned spring-driven opening and closing mechanism, when one end of the inflatable portion 140 or the tube body is not assembled to the air valve 141, the switching assembly 144 can also be switched to press the spring, placing the air valve 141 in an open state. Alternatively, when one end of the inflatable portion 140 or the tube body is assembled to the air valve 141, the switching assembly 144 can also prevent the spring from being pressed, placing the air valve 141 in a closed state. When one end of the inflatable portion 140 or the tube body is connected to the air valve 141, the air valve 141 is opened by the connection relationship of the inflatable portion 140 or the tube body, or by control of the switching assembly 144, and the inflatable portion 140 can then inflate the airbag 13. Furthermore, the user can operate the switch assembly 144 to switch, or remove the inflatable portion 140 or the tube to close the air valve 141, thereby preventing the air in the airbag 13 from flowing out through the air valve 141. In some embodiments, the air valve 141 and the switch assembly 144 can be integrated into a Schrader valve structure to reduce the overall weight of the joint support device E.

[0055] Referring again to Figures 1 and 2 , one end of each adjustment strap 15 is connected to the outer surface of the second sheet 112, which serves as the outer surface of the covering body 11. The other end of each adjustment strap 15 is provided with a fixing portion 151. Each fixing portion 151 can be fixed to the outer surface of the second sheet 112, serving as the outer surface of the covering body 11. When each adjustment strap 15 is tightened and fixed to the outer surface of the covering body 11, the fixing portion 151 can be positioned so that the inner surface of the covering body 11 rests against the skin of a human joint, such as a knee. In some embodiments, the fixing portion 151 can be at least one fastening element, such as a Velcro fastener, a button, or a hook. The outer surface of the covering body 11 can be provided with a fixing structure corresponding to and capable of securing the fixing portion 151, such that the fixing portion 151 can be fixed to the outer surface of the covering body 11 via the fixing structure.

[0056] Referring again to Figures 2 and 3 , in some embodiments, the covering structure 1 includes at least two adjustment straps 15, one of which is longer than the other. The first length of the longer adjustment strap 15, from one end connected to the outer surface of the second sheet 112 to the free end of the fixing portion 151 thereof, is between 57.6 and 70.4 centimeters, preferably between 62.7 and 65.3 centimeters. Furthermore, the second length of the shorter adjustment strap 15, from one end to the free end of the fixing portion 151 thereof, is between 51.3 and 62.7 centimeters, preferably between 55.9 and 58.1 centimeters.

[0057] Referring again to Figures 2 and 3 , in some embodiments, the maximum heights of the first and second plates 111, 112, along their longitudinal axes are 31.1 to 37.9 centimeters, preferably 33.8 to 35.2 centimeters. The second plate 112 comprises a first extension 1121, a second extension 1122, a third extension 1123, and a fourth extension 1124. The first extension 1121 and the second extension 1122 are positioned opposite each other, while the third extension 1123 and the fourth extension 1124 are positioned opposite each other. The end of the longer adjustment strap 15 connected to the second plate 112 corresponds to the first extension 1121, while the end of the shorter adjustment strap 15 connected to the second plate 112 corresponds to the third extension 1123. In some embodiments, a third length from the free end of the first extension portion 1121, along a direction perpendicular or substantially perpendicular to the longitudinal axis of the second sheet 112, to the free end of the second extension portion 1122 is between 50.0 and 58.2 centimeters, preferably between 53.0 and 55.2 centimeters. A fourth length from the free end of the third extension portion 1123, along a direction perpendicular or substantially perpendicular to the longitudinal axis of the second sheet 112, to the free end of the fourth extension portion 1124 is between 44.3 and 52.1 centimeters, preferably between 47.2 and 49.2 centimeters. In some embodiments, the third length is between 43.0 and 50.0 centimeters, preferably between 45.6 and 47.4 centimeters; and the fourth length is between 37.7 and 44.3 centimeters, preferably between 40.2 and 41.8 centimeters.

[0058] Referring again to FIG. 2 , the first sheet 111 has a fifth extension portion 1111, a sixth extension portion 1112, a seventh extension portion 1113, and an eighth extension portion 1114, wherein the fifth extension portion 1111, the sixth extension portion 1112, the seventh extension portion 1113, and the eighth extension portion 1114 correspond to the first extension portion 1121, the second extension portion 1122, the third extension portion 1123, and the fourth extension portion 1124, respectively, and the fifth extension portion 1111 and the sixth extension portion 1112 are located opposite to each other, while the seventh extension portion 1113 and the eighth extension portion 1114 are located opposite to each other. In some embodiments, a fifth length from the free end of the fifth extension portion 1111, along a direction perpendicular or substantially perpendicular to the longitudinal axis of the first sheet 111, to the free end of the sixth extension portion 1112 is between 50.0 and 58.2 centimeters, preferably, the third length is between 53.0 and 55.2 centimeters. A sixth length from the free end of the seventh extension portion 1113, along a direction perpendicular or substantially perpendicular to the longitudinal axis of the first sheet 111, to the free end of the eighth extension portion 1114 is between 44.3 and 52.1 centimeters, preferably, the sixth length is between 47.2 and 49.2 centimeters. In some embodiments, the fifth length is between 43.0 and 50.0 centimeters, preferably between 45.6 and 47.4 centimeters; and the sixth length is between 37.7 and 44.3 centimeters, preferably between 40.2 and 41.8 centimeters.

[0059] Referring again to Figures 2 and 3 , at least one electrode pad unit 2 can be disposed on the outer surface of the first sheet 111 (i.e., the inner surface of the covering structure 1 ), and can include various conductive materials such as conductive fibers, conductive films, or conductive cloth. In some embodiments, the electrode pad unit 2 can be electrically connected to the control device 3 via wires 21 . The control device 3 can be a low-frequency therapy device (also known as a transcutaneous electrical nerve stimulator, TENS), an electrical muscle stimulation device (EMS), or the like. Each electrode pad unit 2 can receive an electronic stimulation signal (current pulse signal) from the control device 3 and output electrical stimulation to the user's joint (e.g., knee) covered by the covering structure 1 to achieve an electrotherapy and / or thermal therapy effect.

[0060] Please refer to Figure 4. The control device 3 can be fixed to the outer surface of the second sheet 112 (i.e., the outer surface of the covering body 11), and it includes at least a DC power supply unit 31 (such as a dry battery), a control unit 32 and a pulse output circuit 33, wherein the DC power supply unit 31 can provide the power required for the operation of the control device 3, and the control unit 32 can generate and transmit a plurality of control signals to the pulse output circuit 33, so that after receiving the power of the DC power supply unit 31, the pulse output circuit 33 can form a current pulse signal of a predetermined waveform according to the content of each of the control signals, and at least one current pulse signal can be transmitted to the electrode pad unit 2 via the wire 21, so that the electrode pad unit 2 can receive each of the current pulse signals and output a current pulse in response to the current pulse signal, thereby stimulating and / or outputting current to heat the user's muscles covered by the joint support device E. Furthermore, the control device 3 is provided with at least one button, so that a user can operate each of the buttons to cause the control device 3 to start and / or stop outputting current pulses, and / or output current pulses of varying magnitudes and / or frequencies. In some embodiments, the control device 3 is capable of receiving wireless signals, such as Bluetooth and / or WiFi signals, so that a user can control the control device 3 to start and / or stop outputting current pulses, and / or output current pulses of varying magnitudes and / or frequencies, by operating a wireless controller.

[0061] Please refer to Figure 5. When the user bends the covering structure 1 to wrap it around at least one human joint, for example, the knee, the upper half of the covering structure 1 can cover the thigh area connected to and adjacent to the knee, the middle area of ​​the covering structure 1 will cover the knee, and the lower half of the covering structure 1 can cover the calf area connected to and adjacent to the knee. Afterwards, the user can pull a single or multiple adjustment straps 15 so that the inner side of the covering structure 1 together with the electrode pad unit 2 can be bent and attached to the skin surface at the aforementioned position. When the knee moves, the inner sides of the upper and lower halves of the covering structure 1 bend toward each other. Therefore, in some embodiments, the covering structure 1 includes at least one support member 16 whose angle can be adjusted. Each of the support members 16 can be made of metal (e.g., aluminum, titanium, stainless steel, etc.), carbon fiber, other materials with high rigidity and / or high tensile strength, so that it can be disposed in the covering structure 1 and provide support to the human joint covered by the covering structure 1 through its rigidity and / or high tensile strength and adjustable fixed configuration. The support member 16 includes at least two plates 161, which can be opposite to each other and are designed to be locked at a specific angle. Each of the plates 161 can be adjusted by the user through an angle adjustment component 162. One end of each of the plates 161 can be connected to the angle adjustment assembly 162, so that the angle adjustment assembly 162 can hinge one end of each of the plates 161 to each other, and according to the needs of the user, each of the plates 161 can be fixed at an intersection angle that the user deems appropriate. The angle adjustment assembly 162 is provided with an angle scale unit and a locking unit, wherein the angle scale unit can be operated by the user to adjust and display the angle between each of the plates 161. Therefore, the user can choose the angle that he deems appropriate according to his own needs, for example, an angle that allows each of the plates 161 to support the human joints but does not hinder the movement of the human joints; the locking unit can lock each of the plates 161 at the angle selected by the user. The other end of each plate 161 away from the angle adjustment component 162, that is, the two ends of the support member 16, can be respectively accommodated in a slot 17 provided on the outer surface of the enclosure 11, and can be restricted in movement by each corresponding slot 17. In this way, the support member 16 capable of adjusting the angle can effectively provide support for the human joint. In some embodiments, the slot 17 can be a covering structure formed by other components covering the outer surface of the enclosure 11, or a covering structure integrally formed on the outer surface of the enclosure 11, and a space is formed between the covering structure and the outer surface of the enclosure 11 to accommodate the other end of the plate 161.In some embodiments, one end of the adjustment strap 15 connected to the outer surface of the second sheet 112 can be fixed to the aforementioned covering structure, and the covering structure can be made of fabric, plastic, or other materials, and its structure and strength are sufficient to withstand the regular pulling force applied by the user. In some embodiments, the other end of the plate 161 can be provided with an opening to reduce the weight of the plate 161 and / or to enable the plate 161 to be connected to the connecting structure formed in the narrow slot 17 to improve the fixation between the plate 161 and the narrow slot 17. After completing the aforementioned pulling operation of each of the adjustment straps 15, the user can operate the inflation device 14 to inflate the airbag 13. Without causing discomfort to the user, the inflated airbag 13 can force the electrode pad unit 2 to be tightly attached to the skin surface. When a user uses the joint support device E on a joint (e.g., a knee) while walking or running, the covering body 11 bends with the movement of the knee, and the airbag 13 also deforms. At this time, the air in the airbag 13 cannot be discharged and is retained within the airbag 13. Therefore, the air continuously applies pressure to the first sheet 111 through the airbag 13, allowing the first sheet 111 and the electrode pad unit 2 thereon to tightly adhere to the skin surface of the knee wrapped by the joint support device E. This prevents the electrode pad unit 2 from detaching due to frequent knee movement. Furthermore, as the airbag 13 expands, the covering structure 1 can reduce the fluid accumulated around the joint through its pressure, achieving an effect equivalent to compression therapy. Generally speaking, compression therapy applies pressure to the affected area (e.g., the leg) to slowly stretch the vein walls and improve blood circulation. Therefore, the user can adjust the inflation of the airbag 13 according to the severity of the blood flow constriction to change the pressure applied by the covering structure 1 on the skin.

[0062] In some embodiments, the configuration and shape of the covering structure 1 can be changed according to the contour of the human joint. Please refer to Figure 6. When the human joint that needs care is the ankle, the covering structure 1 can cover the ankle joint, as well as part of the calf and sole adjacent to the ankle joint. In addition, two electrode pad units 2 can be provided on the inner side of the covering structure 1, one electrode pad unit 2 corresponding to the inner ankle area, and the other electrode pad unit 2 corresponding to the outer ankle area. However, in other embodiments of the present application, the position of each of the electrode pad units 2 can be changed according to product requirements and is not limited to the position drawn in Figure 6. In addition, the control device 3 can be fixed on the covering structure 1 and can transmit electrical stimulation signals (current pulse signals) to each of the electrode pad units 2. When the covering structure 1 has been covered to the ankle, the control device 3 will be located on the outside of the calf. Taking Figure 6 as an example, the control device 3 is located on the right outside of the right calf. In this way, when the user walks, the control device 3 can be prevented from being touched or hit by the left calf to avoid one or more buttons on the control device 3 being accidentally touched or causing discomfort to the user while walking, but the present application is not limited to this.

[0063] Continuing from the above, please refer to Figure 6 again. The airbag 13 can be set in the covering structure 1 and will not be exposed. In order to avoid the diagram being too complicated, only one airbag 13 is drawn in Figure 6, but ideally, the covering structure 1 can be provided with two airbags 13, and each of the airbags 13 will correspond to the position of each of the electrode pad units 2 respectively. In this way, when each of the airbags 13 is inflated, it can force each of the electrode pad units 2 to be closely attached to the skin surface to maintain good electrotherapy and thermal therapy effects. In addition, after the covering structure 1 covers the ankle, the adjustment strap 15 can be wrapped around the outer side of the covering structure 1 to fix the covering structure 1. In this embodiment, the adjustment strap 15 can first wrap around the ankle joint and then wrap around the instep toward the inner side of the sole without wrapping the heel. The aforementioned wrapping method can provide better stability for the ankle, but is not limited to this. As long as the adjustment strap 15 can stabilize the covering structure 1 in its current position and does not disengage due to the user's movements, it falls within the scope of protection of this application. Furthermore, according to the user's needs, if the covering structure 1 needs to maintain a specific joint state, for example, to keep an injured joint bent or straight within a limited range, the covering structure 1 can also be provided with a metal or semi-rigid rod so that after the covering structure 1 is wrapped around the human joint, the joint can be stably maintained in the desired specific state and limited range through the aforementioned rod.

[0064] In some embodiments, as shown in Figures 7 and 8, the covering structure 1 can be made of at least one elastic material (e.g., nylon plus latex) and be cylindrical in shape, forming a sleeve space 10 therein, and can be fitted over a human joint, such as an ankle. Furthermore, one or more electrode pad units 2 can be disposed inside the covering structure 1, and the control device 3 can be fixed to the covering structure 1. Because the diameter of the covering structure 1 in its unstretched state is smaller than the outer diameter of the human joint where the joint support device E is to be worn, when the joint support device E is worn over a human joint (e.g., an ankle), the covering structure 1 is stretched by the human joint, and the force generated by its own elasticity causes its inner surface to contact the skin surface of the joint. Thus, the covering structure 1 not only deforms to accommodate the flexion of the ankle but also forces the electrode pad units 2 to closely contact the skin surface.

[0065] In embodiments where the covering structure 1 is made of at least one elastic material, because the covering structure 1 achieves a close fit against the skin surface through elasticity, the covering structure 1 can change its shape or contour to accommodate different human joints. Furthermore, the covering structure 1 can be manufactured into specific shapes and contours, or include other components to create configurations that conform to different human joints. For example, the joint support device E shown in FIG. 9 is designed to fit over the elbow joint; the joint support device E shown in FIG. 10 is designed to fit over the shoulder joint; the joint support device E shown in FIG. 11 is designed to fit over the knee joint; and the joint support device E shown in FIG. 12 is designed to fit over the wrist joint. In some embodiments, the joint support device E can be applied to other parts of the body beyond the joints. For example, as shown in FIG. 13 , the joint support device E is designed to fit over the calf. As shown in FIG. 14 , the joint support device E is designed to wrap around the user's waist and includes at least one airbag 13, one or more electrode pad units 2, and an inflatable device 14. Each electrode pad unit 2 can be positioned above or in front of a corresponding airbag 13, so that after the airbag 13 is inflated by the inflatable device 14, the expansion of the airbag 13 causes each electrode pad unit 2 to be tightly pressed against the user's skin. In some embodiments, when the joint support device E is wrapped around the user's waist, the airbag 13 and electrode pad unit 2 can also correspond to the lower back region associated with the waist to alleviate symptoms associated with lower back pain. However, the present application is not limited to this, and the airbag 13 and electrode pad unit 2 can be positioned anywhere on the joint support device E according to the user's actual needs. In some embodiments, the inflatable device 14 can include at least one manual or electric air pump.

[0066] Through the above structure, when the user is alone, he can easily adjust the position of the electrode pad unit 2 by pulling the covering structure 1, so that the electrode pad unit 2 can be moved to the position where electrotherapy and / or thermal therapy is required, greatly improving the convenience of use.

[0067] Furthermore, the control device 3 can be positioned on the covering structure 1 via a positioning member H. The positioning member H has a release / locking mechanism L. The release / locking mechanism L can secure the control device 3 to the positioning member H and can also release the control device 3 from the positioning member H (i.e., the control device 3 can be detached from the positioning member H). In this way, when a user needs to wash the covering structure 1, the control device 3 can be removed from the positioning member H to prevent damage to the control device 3. In some embodiments, the release / locking mechanism L can be a harness with a buckle. In addition, the positioning member H can be provided with a conductive portion to transfer the power generated by the control device 3 and / or the portable battery unit thereon / therein to each of the electrode pad units 2, so that each of the electrode pad units 2 can provide electrotherapy and / or thermal therapy.

[0068] Various aspects of the positioning member H are now described. Please refer to Figures 15 to 18. In some embodiments, the positioning member H includes a substrate H11, a positioning body H12, an inner plate H13, a plurality of conductive parts H14 and a plurality of wire connecting parts H15, wherein the substrate H11 and the positioning body H12 can be assembled with each other, and at least one Velcro is provided on the rear side of the substrate H11 so that it can be attached to the covering structure 1; the positioning body H12 can be made of at least one elastic material, and a receiving groove H120 is provided on the front side thereof; the inner plate H13 will be located at the bottom of the receiving groove H120, and the inner diameter of the receiving groove H120 will be slightly smaller than the control groove H120. The outer diameter of the control device 3 (for example, its inner diameter can be approximately 0.1% to 5% smaller than the outer diameter of the control device 3). When the control device 3 is placed in the accommodating groove H120, the groove wall of the accommodating groove H120 can expand slightly due to its own elasticity and cover the outer periphery of the control device 3 tightly to form the release / locking mechanism L, so that the control device 3 is positioned on the positioning body H12; when the control device 3 is pulled outward, as long as the aforementioned pulling force is greater than the fixing force (i.e., friction force or clamping force) applied to the control device 3 by the groove wall of the accommodating groove H120 (release / locking mechanism L), the control device 3 can be separated from the release / locking mechanism L.

[0069] Continuing from the above, referring again to Figures 15 to 18, the conductive portions H14 can extend into the receiving groove H120 and sequentially pass through the inner plate H13 and the bottom of the receiving groove H120 to the substrate H11. The wire connecting portions H15 are located between the positioning body H12 and the substrate H11 and are electrically connected to the corresponding conductive portions H14. Each of the wire connecting portions H15 can be electrically connected to at least one external wire (e.g., wire 21). In addition, a plurality of power conducting portions 35 are provided on the rear side of the control device 3. When the control device 3 is placed in the receiving groove H120, each of the power conducting portions 35 is electrically connected to each of the corresponding conductive portions H14, so that the current (current pulse signal) output by the control device 3 can be transmitted sequentially through the power conducting portion 35 and the conductive portion H14 to the wire connecting portion H15. However, in other embodiments of the present application, the conductive portion H14 and the wire connecting portion H15 can be integrated into a single component (equivalent to omitting the wire connecting portion H15 ), so that each conductive portion H14 can be electrically connected to an external wire.

[0070] In addition to the aforementioned release / lock mechanism L, as shown in Figures 19-21 , in some embodiments, the positioning member H includes a base plate H21, a positioning body H22, and a plurality of conductive portions H24. The base plate H21 and positioning body H22 can be assembled into a single unit, and the conductive portions H24 can be fixed to the positioning body H22. Furthermore, the positioning body H22 has at least one protruding rail H211 protruding from the front side, which serves as the release / lock mechanism L. The control device 3 has at least one recess 37 on its rear side, and the width and / or length of each recess 37 is slightly smaller than the width and / or length of each protruding rail H211, for example, by 0.1% to 5% less than the width of each protruding rail H211. When the control device 3 is assembled to the positioning member H, each protruding rail H211 fits into its corresponding recess 37, and the power conducting portion 35 is electrically connected to the corresponding conductive portion H24. Then, when the control device 3 is pulled outward, the control device 3 can be separated from the release / locking mechanism L as long as the pulling force is greater than the clamping force between the groove 37 and the protruding rail H211.

[0071] Please refer to Figures 22 to 24. In some embodiments, the positioning member H includes at least one substrate H31, a positioning body H32, and a plurality of conductive portions H34. The front side of each substrate H31 can be attached to the rear side of the positioning body H32, and the rear side of each substrate H31 can be attached to a connecting plate H30 (e.g., at least one Velcro). The positioning body H32, the substrate H31, and the connecting plate H30 can be assembled into one by a plurality of fasteners H36. A accommodating groove H320 is provided on the front side of the positioning body H32, and the control device 3 can be placed in the accommodating groove H320, and the groove wall of the accommodating groove H320 will form the release / locking mechanism L; the base plate H31 is not covered by the positioning body H32 and is further provided with at least one fixing component H37 (such as a button). The fixing component H37 can be interlocked with another corresponding fixing component on the covering structure 1, so that the positioning member H can be more firmly positioned on the covering structure 1.

[0072] As described above, when the control device 3 is fixed to the positioning member H, the user can move and walk freely without causing the control device 3 to fall off. Whether the user is working or exercising, the release / locking mechanism L is sufficient to firmly fix the control device 3 on the covering structure 1 and prevent the control device 3 from falling off the covering structure 1.

[0073] Furthermore, when the user needs to clean the covering structure 1, the release / locking mechanism L can be unlocked before the covering structure 1 is washed, allowing the control device 3 to be separated from the retaining member H, thereby preventing the components within the control device 3 from being damaged by water. Furthermore, the release / locking mechanism L can be directly disposed on the covering structure 1 (i.e., not indirectly disposed on the covering structure 1 via the retaining member H) and electrically connected to one or more electrode pad units 2 to transmit current to the one or more electrode pad units 2.

[0074] Referring to FIG. 25A , in some embodiments, the electrode pad unit 2 can be provided with an electrotherapy unit EU. The electrotherapy unit EU comprises a conductive layer 211 and, optionally, a covering layer 212 and a connecting layer 213. The conductive layer 211 can be made of conductive fiber, conductive film, conductive cloth, aluminum foil, a mixture thereof, or other conductive materials. The optional covering layer 212 (e.g., a layer of fabric or a layer of conductive gel) is provided on one side of the conductive layer 211, while the connecting layer 213 is provided on the other side of the conductive layer 211. The conductive layer 211 can be electrically connected to a metal member 22, and the metal member 22 can be electrically connected to an electrical wire 21. In this embodiment, the electrical wire 21 is secured to the metal member 22 by wrapping it with an insulating tape 217. Furthermore, the connecting layer 213 (e.g., adhesive) can be fixed to the first sheet 111. When the user uses the joint support device E, the conductive layer 211 or the covering layer 212 (if the electrode pad unit 2 is provided with a covering layer 212) can be attached to the skin surface of the human joint. After the wire 21 is electrically connected to the control device 3, it can receive power from the control device 3 (e.g., a TENS or EMS device), allowing the electrode pad unit 2 to output electrical stimulation to the user's joint to achieve an electrotherapy effect. However, the electrode pad unit 2 is not limited to the aforementioned structure. In other embodiments of the present application, the covering layer 212 can be omitted, allowing the conductive layer 211 to directly contact the skin. The connecting layer 213 can be a fabric (e.g., non-woven fabric, cotton fabric), and can be connected to a conductive sheet (e.g., aluminum foil) to better bond to the first sheet 111.

[0075] Referring to FIG. 25B , in some embodiments, the electrode pad unit 2 can be provided with a heat therapy unit HU. The heat therapy unit HU can be composed of two insulating layers 218 (e.g., non-woven fabric) and a heating layer 219. The heating layer 219 can be made of a metal material (e.g., iron-chromium-aluminum alloy wire, nickel-chromium alloy wire), graphene, carbon fiber, or other electrothermal materials to generate heat when current passes through it. The heating layer 219 is located between the two insulating layers 218, and the outer surface of one insulating layer 218 can be fixed to the opposing first sheet 111. The heating layer 219 can be electrically connected to the metal part 22 to receive electricity from the control device 3 through an electric wire 21, thereby causing the electrode pad unit 2 to generate heat and dissipate it through each of the insulating layers 218 to heat the user's joints, thereby relaxing the blood vessels and promoting local blood circulation to increase the metabolic rate, thereby accelerating the excretion of inflammatory substances from the human body to improve the self-repair ability of muscle tissue. At the same time, hot compress (thermotherapy) can also increase the elasticity of human soft tissue to reduce muscle spasms, thereby alleviating the pain suffered by the human body and relaxing the mood. However, in other embodiments of the present application, the electrode pad unit 2 can also omit the insulating layer 218, and the heating layer 219 can directly contact the skin.

[0076] Please refer to Figure 25C. In some embodiments, the electrode pad unit 2 can be an electrotherapy / thermal therapy hybrid unit, which can be formed by superimposing the aforementioned electrotherapy unit EU and thermal therapy unit HU. For example, a heating layer 219 is arranged between two insulating layers 218, and the outer surface of one of the insulating layers 218 can be covered with a conductive layer 211 (such as conductive fiber). The heating layer 219 and the conductive layer 211 can receive electricity from the control device 3 through the same or different metal parts 22, wherein the conductive layer 211 can output electrical stimulation to the user's human joints, and the heating layer 219 can generate heat, and the heat is passed through the insulating layer 218 and the conductive layer 211 to heat the user's human joints.

[0077] The above description is only a preferred feasible embodiment of the present application and does not limit the scope of protection of the claims of the present application. Therefore, any equivalent changes that a person skilled in the art can think of without creative work based on the technical content disclosed in the present application should be included in the scope of protection of the claims of the present application.
