[0018] The main benefits of this application are:

[0019] 1. When the finger is bent, the first and second elastic metal plates can change with the direction of the user's finger bending. Under the action of the force in the opposite direction of the bending arc, it achieves the exercise effect. When the user's finger is bent to its own limit, the first and second elastic metal plates restore the user's finger to the starting position under the action of the restoring force. The overall structure is simple and easy to operate. It can be worn in daily life without affecting the user's daily operation. At the same time, ordinary daily hand movements can meet the exercise requirements. In addition, the overall structure has the advantages of being waterproof, drop-resistant and lightweight during wear, improving the user experience while realizing autonomous control of exercise.

[0020] 2. The degree of finger movement can be determined by monitoring the pressure values ​​of the first and second pressure sensors. When the values ​​monitored by the first and second pressure sensors increase and then decrease, it can also indicate one exercise session. Depending on the actual situation, the values ​​of the first and second pressure sensors can be selected as the effective exercise threshold. That is, when the values ​​monitored by the first and second pressure sensors exceed the set threshold, it indicates that the exercise is effective. After receiving the data, the controller will display it to the user on the screen. The user can then observe the exercise status on the screen, which can monitor the user's exercise status to ensure that daily exercise meets the training intensity prescribed by the doctor.

[0021] 3. The ventilation holes on the first, second, and third finger sleeves allow for ventilation to prevent the fingers from getting stuffy and causing adverse effects. The ventilation holes also increase the deformation range of the first, second, and third finger sleeves to fit the fingers of different users. At the same time, the device allows users to effectively perceive the outside world by touching it with their fingers, ensuring feedback of sensory signals.

[0041] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 11One or more embodiments provide an assistive rehabilitation device for hand dysfunction, comprising: a housing 100, wristbands 101 disposed on both sides of the housing 100, and a cavity 102 and a slot formed inside the housing 100; a finger rehabilitation assembly 200, comprising a first elastic metal sheet 201 and a first finger sleeve 202, the first finger sleeve 202 having a first perforation 203 and a first opening 204 inside, the first perforation 203 for a finger to pass through, one end of the first elastic metal sheet 201 extending into the cavity 102, and the other end of the first elastic metal sheet 201 extending into the first opening 204 and connecting to the inner wall of the opening; and a thumb rehabilitation assembly 300, comprising an insert 30 1. A second elastic metal sheet 302 and a second finger sleeve 303, the second finger sleeve 303 having a second through hole 304 and a second opening 305 inside, the second through hole 304 for the thumb to pass through, one end of the second elastic metal sheet 302 extending into the interior of the second opening 305 and connecting with the inner wall of the second opening 305, the surface of the second elastic metal sheet 302 having a fixing elongated hole 306, the insert 301 being inserted into the slot, the insert 301 having an installation hole inside, and also including an installation rod 307, one end of the installation rod 307 being threadedly connected to the fixing elongated hole 306 and the installation hole in sequence, the first elastic metal sheet 201 and the second elastic metal sheet 302 having a pressed bending arc, and one end of the first elastic metal sheet 201 having a raised arc.

[0042] In this embodiment, the user inserts the corresponding finger into the first perforation 203 and the second perforation 304 of the corresponding first finger sleeve 202 and second finger sleeve 303. Then, the user wears the housing 100 on their wrist via the wristband 101. Next, one end of the first elastic metal piece 201 is inserted into the cavity 102, and the insert block 301 is inserted into the slot. One end of the mounting rod 307 is connected sequentially to the fixing elongated hole 306 and the mounting hole. The second elastic metal piece 302 can be adjusted to fit the user's thumb length by the number of rotations of the mounting rod 307 and the threaded connection position between the mounting rod 307 and the fixing elongated hole 306. When the user bends their finger during wear, the first elastic metal piece 201 and the second elastic metal piece 302... The metal plate 302 can change according to the bending direction of the user's finger. Since the first elastic metal plate 201 and the second elastic metal plate 302 apply force in the opposite direction of the bending arc, the user's finger will have a training effect under the action of the force in the opposite direction of the bending arc during the bending process. When the user's finger bends to its own limit, the first elastic metal plate 201 and the second elastic metal plate 302 will restore the user's finger to the starting position under the action of the restoring force. It should be noted that multiple dividing posts 106 are provided in the cavity 102. The dividing posts 106 divide the space in the cavity 102 to limit the first elastic metal plate 201 and ensure the stability of the insertion and exit displacement of the first elastic metal plate 201.

[0043] In this embodiment, the materials of the first elastic metal sheet 201 and the second elastic metal sheet 302 can be stainless steel or titanium alloy, etc. The first elastic metal sheet 201 and the second elastic metal sheet 302 need to be pre-pressed to have an initial bending arc, and the bending arc direction is the same as the finger bending direction. The thickness, width, or material of the first elastic metal sheet 201 and the second elastic metal sheet 302 can be adjusted according to the actual situation to achieve the assistance provided by the first elastic metal sheet 201 and the second elastic metal sheet 302. The use of the finger rehabilitation component 200 is applicable to the four limbs other than the thumb, while the thumb rehabilitation component 300 is applicable to all five fingers, and the number can be adjusted according to the usage. The accompanying drawings of this application illustrate four fingers. The number of components 200 can be adjusted according to actual needs, allowing for the use of various structures for all five fingers. The total number of finger rehabilitation components 200 and thumb rehabilitation components 300 is preferably three, used for the thumb, index finger, and middle finger. The number can be increased or decreased as needed. Note that if only the thumb is used, the device lacks wrist support functionality. The fingertip area requires relatively less support; therefore, the distal ends (finger tips) of the first elastic metal sheet 201 and the second elastic metal sheet 302 can be narrowed, grooved at the edges, and internally grooved to reduce rebound force. The connection between the mounting rod 307 and the fixing elongated hole 306 and the mounting hole is preferably a threaded connection, including but not limited to the above-mentioned connection methods.

[0044] Please see Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 10 and Figure 11 In some embodiments, a first pressure sensor 103 is provided on the inner wall of the cavity 102, and the surface of the first pressure sensor 103 abuts against one end of the first elastic metal sheet 201. A second pressure sensor 308 is provided on the surface of the mounting rod 307. A controller 104 and a display screen 105 are provided inside the housing 100. The first pressure sensor 103, the second pressure sensor 308, and the display screen 105 are all communicatively connected to the controller 104. The housing also includes a terminal, which includes a display and a wireless communication device. The display and the wireless communication device are electrically connected, and the wireless communication device is communicatively connected to the controller 104. A player is provided inside the housing 100, and the player is communicatively connected to the controller 104. The first pressure sensor 103 is a thin-film pressure position sensor, the second pressure sensor 308 is a resistive thin-film pressure sensor, and one end of the first elastic metal sheet 201 has a raised arc.

[0045] In this embodiment, the curved arc of one end of the first elastic metal sheet 201 abuts against the surface of the first pressure sensor 103. When the user's finger bends, the first elastic metal sheet 201 will move outward from the cavity 102. When the user returns to the initial position, the first elastic metal sheet 201 will continue to move inward from the cavity 102. During this process, the contact position between the first elastic metal sheet 201 and the first pressure sensor 103 will change, thereby indicating the pressure. The degree of finger movement can be determined by the position of the first elastic metal sheet 201 in the cavity 102. As the second elastic metal sheet 302 deforms with the user's thumb, it will apply pressure to the second pressure sensor 308. The change in pressure value is linearly related to the bending angle of the second elastic metal sheet 302. That is, the greater the pressure detected by the second pressure sensor 308, the greater the bending angle of the second elastic metal sheet 302, thus allowing a direct indication of the degree of finger movement.

[0046] In this embodiment, the user's finger movement can be determined by monitoring the pressure values ​​monitored by the first pressure sensor 103 and the second pressure sensor 308. The values ​​monitored by the first pressure sensor 103 and the second pressure sensor 308 are transmitted to the controller 104. When the values ​​monitored by the first pressure sensor 103 and the second pressure sensor 308 show an increase followed by a decrease, it can also indicate one exercise session. After receiving the data, the controller 104 displays it to the user on the display screen 105. The user can then observe the exercise status by observing the display screen 105. At the same time, the display screen 105 can display information such as time and date, and can play relevant music and other information to relieve the user's mental stress. Simultaneously, the controller 104 transmits relevant information to the wireless communication device, displaying the user's exercise status on the display. The first pressure sensor can be selected according to the actual situation. The values ​​of force sensor 103 and second pressure sensor 308 are used as the effective training threshold. That is, when the values ​​monitored by the first pressure sensor 103 and the second pressure sensor 308 exceed the set threshold, it indicates that the exercise is effective. Ordinary daily hand movements can meet the training requirements, such as grasping objects, playing with a mobile phone, and dressing. These actions will cause the user's fingers to bend, thereby achieving the exercise. By recording the exercise and the number of effective exercises, the training intensity can be monitored according to the doctor's orders or the training provided by medical staff. It should be noted that because the condition of patients with hand dysfunction varies, the actual value of the effective training threshold is adjusted according to the actual situation. The adjustment can be made by observing the user's finger bending. When the bending angle meets the effective exercise angle judged by medical staff, it is also indicated that it is an effective training threshold. The threshold setting is adjusted according to the actual situation.

[0047] It should be noted that the specific models and specifications of the first pressure sensor 103, the second pressure sensor 308, the display screen 105, the player, the controller 104, the wireless communication device, and the display in this disclosure need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here. Its power supply and its principle are clear to those skilled in the art, so they will not be described in detail here.

[0048] Please see Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 11 In some embodiments, a joint pad 400 is also included. The joint pad 400 includes a fixing plate 401, a rod 402, a limiting plate 403, and a pad member 404. The rod 402 is disposed on the top of the fixing plate 401, and the pad member 404 is disposed on the bottom of the fixing plate 401. The limiting plate 403 has a limiting groove and a limiting hole inside. The limiting groove and the limiting hole match each other. The shape and size of the limiting groove match the shape and size of the fixing plate 401. The fixing plate 401 is located inside the limiting plate 403. The bottom of the limiting plate 403 is connected to the top of the pad member 404. The first elastic metal sheet 201 and the second elastic metal sheet 302 both have fixing holes 405 inside. There are multiple fixing holes 405. The rod 402 can pass through the fixing holes 405.

[0049] In this embodiment, the fixing plate 401 and the insert rod 402 adopt an integral molding structure, connecting the fixing plate 401, the limiting plate 403, and the pad 404 into a whole. During the connection process, it is necessary to ensure that the fixing plate 401 is placed in the limiting groove, the insert rod 402 passes through the limiting hole, the joint pad 400 is placed in the fixing hole 405, and one end of the insert rod 402 passes through the fixing hole 405 to realize the connection between the joint pad 400 and the first elastic metal sheet 201 and the second elastic metal sheet 302. The joint pad 400 on the first elastic metal sheet 201 is installed at the metacarpophalangeal joint and the proximal interphalangeal joint. There are multiple fixing holes 405 to accommodate different finger sizes. The joint pad 400 on the second elastic metal sheet 302 is installed at the first metacarpophalangeal joint of the thumb. It should be noted that the connection between the joint pad 400 and the first elastic metal sheet 201 or the second elastic metal sheet 302 can be adjusted to an adhesive method according to the actual situation, which is also the subject of protection of this application.

[0050] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 11In some embodiments, a third finger sleeve 500 is also included. The third finger sleeve 500 has a third perforation 501 and a through hole 502 inside. The third perforation 501 is for the finger to pass through, and the through hole 502 is for the first elastic metal sheet 201 to pass through. The first finger sleeve 202, the second finger sleeve 303 and the third finger sleeve 500 all have ventilation holes 600 inside.

[0051] In this embodiment, the first finger sleeve 202, the second finger sleeve 303, and the third finger sleeve 500 are all made of elastic material and can deform to fix the user's finger. To improve the positional stability of the first elastic metal piece 201, it can pass through the through hole 502 before the first elastic metal piece 201 is connected to the first finger sleeve 202. When wearing it, the user can pass their finger through the first through hole 203 and the third through hole 501 of the third finger sleeve 500 and the first finger sleeve 202 in sequence. The ventilation holes 600 on the first finger sleeve 202, the second finger sleeve 303, and the third finger sleeve 500 can allow for ventilation to avoid the adverse effects of the fingers being stuffy.

[0052] It should be noted that the first elastic metal sheet 201 slides within the cavity 102. As the user's finger bends, the first elastic metal sheet 201 will flow out of the cavity 102, and the flow limit distance will not cause the first elastic metal sheet 201 to flow out completely. The first elastic metal sheet 201 and the second elastic metal sheet 302 have advantages such as small size, few parts, waterproof, drop-resistant and lightweight during use. Furthermore, the actual size of the finger rehabilitation component 200 and the thumb rehabilitation component 300 can be customized according to the user's size to meet different user needs. Moreover, this device does not need to distinguish between left and right hands. To meet the use of left and right hands, the position of the thumb rehabilitation component can be adjusted. It should be noted that the slots are symmetrically opened with respect to the center line of the housing 100.

[0053] Specifically, the working principle of the assistive rehabilitation device for hand dysfunction provided in this application is as follows:

[0054] The user inserts the corresponding finger into the first perforation 203, second perforation 304, and third perforation 501 of the corresponding first finger sleeve 202, second finger sleeve 303, and third finger sleeve 500. Then, the user wears the housing 100 on the wrist via the wristband 101. The first elastic metal piece 201 is then inserted through one side of the cavity 102 and exits through the other side. The joint pad insert is then inserted into the fixing hole, and the first elastic metal piece 201 is passed through the through hole 502 and the first opening 204 in sequence, thus completing the wearing of the finger rehabilitation component 200. The insert block 301 is then inserted into the slot, and one end of the mounting rod 307 is connected to the fixing elongated hole 306 and the mounting hole in sequence. The connection position between the mounting rod 307 and the fixing elongated hole 306 can be adjusted to adapt the second elastic metal piece 302 to the length of the user's thumb.

[0055] When the user bends their fingers during wear, the first elastic metal plate 201 and the second elastic metal plate 302 can change with the direction of the user's finger bending. Since the first elastic metal plate 201 and the second elastic metal plate 302 will apply force in the opposite direction of the bending arc, the user's finger will have an exercise effect under the action of the force in the opposite direction of the bending arc. When the user's finger bends to its own limit, the first elastic metal plate 201 and the second elastic metal plate 302 will restore the user's finger to the starting position under the action of the restoring force.

[0056] The user's finger movement can be determined by monitoring the pressure values ​​of the first pressure sensor 103 and the second pressure sensor 308. The values ​​monitored by the first pressure sensor 103 and the second pressure sensor 308 are transmitted to the controller 104. When the values ​​monitored by the first pressure sensor 103 and the second pressure sensor 308 show an increase followed by a decrease, it also indicates one exercise session. After receiving the data, the controller 104 displays it to the user on the display screen 105. The user can then observe the exercise status by observing the display screen 105. At the same time, the display screen 105 can display information such as time and date, and can also play relevant music and other information to relieve the user's mental stress. Simultaneously, the controller 104 transmits relevant information to the wireless communication device, displaying the user's exercise status on the monitor. Depending on the actual situation, the values ​​of the first pressure sensor 103 and the second pressure sensor 308 can be selected as the effective exercise threshold. That is, when the values ​​monitored by the first pressure sensor 103 and the second pressure sensor 308 exceed the set threshold, it indicates that the exercise is effective. Ordinary daily hand movements can meet the exercise requirements, such as grasping objects, playing with a mobile phone, and dressing. These actions will cause the user's fingers to bend, thereby achieving exercise. By recording the exercise and the number of effective exercises, the training intensity can be monitored according to the doctor's orders or the training intensity provided by medical staff.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
