[0036] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] The embodiment of the present invention provides a finger rehabilitation treatment device, such as Figure 1-17As shown, the finger rehabilitation treatment device includes: an arm sleeve 1, a connecting arm plate 2 and a palm plate 3, the arm sleeve 1 is used to be mounted on the forearm, the connecting arm plate 2 is installed on the outer side of the arm sleeve 1 by a lifting mechanism and extends in the direction of the palm, the palm plate 3 is fixedly installed on the side of the connecting arm plate 2 extending in the direction of the palm, and its position corresponds to the palm; a finger movable mechanism, the finger movable mechanism is installed on the palm plate 3, and is arranged according to the finger distribution method; the finger movable mechanism includes a mounting sleeve 4, a telescopic plate 5, a joint movable plate 6, a finger sleeve connecting plate 7, a connecting column 8, a finger sleeve 9 and an elastically adjustable contraction mechanism, the mounting sleeve 4 is fixedly installed on the outer edge of the palm plate 3, the The telescopic plate 5 is slidably installed in the mounting sleeve 4 for adjustment according to the length of the finger. The joint movable piece 6 is hingedly installed on one end of the telescopic plate 5 located outside the mounting sleeve 4. The mounting sleeve 4, the telescopic plate 5, and the joint movable piece 6 are arranged according to the finger distribution method. The finger sleeve connecting piece 7 is fixedly installed on the joint movable piece 6. The connecting column 8 is fixedly installed on the finger sleeve connecting piece 7. The finger sleeve 9 is fixedly installed on the connecting column 8 for finger insertion. The finger sleeve connecting piece 7, the connecting column 8, and the finger sleeve 9 are sequentially arranged along the joint movable piece 6 toward the arm sleeve 1. The elastic adjustable contraction mechanism is arranged on the telescopic plate 5 and the joint movable piece 6 for adjusting the treatment intensity.

[0038] In this embodiment, when the finger rehabilitation treatment device is used, the arm sleeve 1 is first put on the forearm to ensure stability and comfort; then, the height is adjusted by connecting the lifting mechanism on the arm support plate 2 to meet the needs of different patients. At this time, the palm plate 3 is located above the palm; then, the patient inserts their respective fingers into the corresponding finger sleeves 9, and the finger sleeves 9 are connected to the joint movable plate 6 through the connecting column 8 and the finger sleeve connecting plate 7. According to the length of the finger, the position of the telescopic plate 5 in the mounting sleeve 4 can be slidably adjusted to achieve the best adaptation effect.

[0039] During the treatment process, the bending of the finger drives the finger sleeve 9, the connecting column 8, the finger sleeve connecting plate 7 and the joint movable plate 6 to move. The joint movable plate 6 rotates along the telescopic plate 5 to pull the elastic adjustable contraction mechanism. When the finger is reset, the elastic adjustable contraction mechanism pulls the finger to reset. The elastic adjustable contraction mechanism applies appropriate force to the telescopic plate 5 and the joint movable plate 6, thereby performing finger reset and traction treatment. The treatment intensity can be independently adjusted according to the specific situation of each finger to ensure that the treatment process is both effective and comfortable.

[0040] This finger rehabilitation therapy device achieves precise control of the finger treatment force by introducing an elastic adjustable contraction mechanism. This improvement solves the problem of uneven force applied to different parts of multiple fingers in traditional devices, and can independently adjust the treatment force according to the rehabilitation needs of different fingers, avoiding the situation where the local fingers of the hand are over- or under-forced. This not only improves the pertinence and effectiveness of the treatment, but also reduces the discomfort of the patient during the treatment process, and also achieves adaptation to fingers of different lengths through the sliding adjustment function of the telescopic plate 5.

[0041] In a further preferred embodiment of the present invention, a positioning bolt 10 is installed on the installation sleeve 4, and the end of the positioning bolt 10 is in conflict with the telescopic plate 5 to fix the length of the installation sleeve 4 and the telescopic plate 5.

[0042] In this embodiment, after completing the sliding adjustment of the telescopic plate 5 in the mounting sleeve 4, the user can rotate the positioning bolt 10 so that its end is tightly in contact with the telescopic plate 5, thereby fixing the relative position between the two.

[0043] In a further preferred embodiment of the present invention, a joint limiting plate 11 is fixedly installed on the other side of the joint movable plate 6 relative to the finger sleeve connecting plate 7. When the telescopic plate 5 and the joint movable plate 6 are parallel, the joint limiting plate 11 is in contact with the surface of the telescopic plate 5. When the joint movable plate 6 is deflected along the telescopic plate 5, the joint limiting plate 11 is separated from the surface of the telescopic plate 5.

[0044] In this embodiment, a joint stopper 11 is fixedly mounted on the other side of the joint movable sheet 6 relative to the finger sleeve connecting sheet 7. During the treatment process, when the telescopic plate 5 and the joint movable sheet 6 are in a parallel state, the joint stopper 11 contacts the surface of the telescopic plate 5 to form a natural stop point. As the finger bends and stretches, the joint movable sheet 6 deflects along the telescopic plate 5, at which time the joint stopper 11 separates from the surface of the telescopic plate 5, allowing the finger to move within a certain range.

[0045] The introduction of the joint limiting piece 11 limits the deflection range of the joint movable piece 6, which can ensure that the finger will not be excessively or improperly moved during the treatment process, thereby reducing the risk of injury. This improvement not only improves the safety of treatment, but also helps to protect the finger joints and avoid secondary injuries caused by excessive movement.

[0046] In a further preferred embodiment of the present invention, the elastic force adjustable contraction mechanism includes a joint shaft 12, a rectangular sliding cavity 13, a rectangular slider 14, a return spring 15, a pressure regulating bolt 16, a connecting end plate 17, a rope threading tube 18, a rope threading hole 19, a pull rope 20 and a positioning bolt 21, the joint shaft 12 is fixedly installed on the telescopic plate 5, and the joint shaft 12 is rotatably connected to the joint movable plate 6, the rectangular sliding cavity 13 is opened on the joint movable plate 6, the rectangular slider 14 is slidably installed in the rectangular sliding cavity 13, the return spring 15 is arranged in the rectangular sliding cavity 13, the two ends of the return spring 15 are respectively in conflict with the inner wall of the rectangular sliding cavity 13 and the rectangular slider 14, the pressure regulating bolt 16 is threadedly installed on the side of the joint movable plate 6 away from the telescopic plate 5, and the end of the pressure regulating bolt 16 extends to The rectangular sliding cavity 13 is in conflict with the rectangular sliding block 14, and is used to adjust the initial position of the rectangular sliding block 14 in the rectangular sliding cavity 13 and adjust the compression degree of the reset spring 15. The connecting end piece 17 is fixedly mounted on one end of the joint shaft 12, and the rope threading tube 18 is fixedly mounted on the connecting end piece 17. The rope threading hole 19 is opened on the joint movable plate 6 and is connected to the rectangular sliding cavity 13. The position of the rope threading hole 19 is arranged corresponding to the rope threading tube 18. The pull rope 20 is penetrated through the rectangular sliding cavity 13, the rope threading tube 18 and the rope threading hole 19. One end of the pull rope 20 located in the rectangular sliding cavity 13 penetrates the reset spring 15 and is fixedly connected to the rectangular sliding block 14. The positioning bolt 21 is threadedly mounted on the rope threading tube 18, and the end of the positioning bolt 21 is in conflict with the pull rope 20.

[0047] In this embodiment, the elastic force adjustable retracting mechanism of the finger rehabilitation treatment device is used more accurately. First, the joint shaft 12 is fixedly mounted on the telescopic plate 5 and is rotationally connected with the joint movable plate 6 to ensure the natural bending and extension of the finger during the rehabilitation process. The rectangular sliding cavity 13 is opened on the joint movable plate 6, and the rectangular slider 14 is slidably mounted in the rectangular sliding cavity 13. The reset spring 15 is arranged in the rectangular sliding cavity 13 to provide an initial reset force for the rectangular slider 14. The user can adjust the position of the pressure regulating bolt 16 on the joint movable plate 6 by rotating it, thereby changing the initial position of the rectangular slider 14 in the rectangular sliding cavity 13, and then adjusting the compression degree of the reset spring 15, and at the same time adjusting the length of the pull rope 20 to achieve precise control of the treatment intensity.

[0048] A pull rope 20 passes through the rectangular sliding cavity 13, the rope threading tube 18 and the rope threading hole 19, one end of which is fixedly connected to the rectangular sliding block 14, and the other end is fixed to the rope threading tube 18 by a positioning bolt 21.

[0049] During use, since the pressure-adjusting bolt 16 needs to be adjusted, the positioning bolt 21 needs to be brought in to allow the pull rope 20 to slide freely for adjustment. After the pressure-adjusting bolt 16 is adjusted, the length of the pull rope 20 between the rectangular slider 14 and the rope threading tube 18 is determined, and the positioning bolt 21 can be re-tightened at this time.

[0050] During the treatment process, as the fingers bend and extend, the joint movable piece 6 rotates along the joint axis 12, and the joint axis 12 is fixed to the telescopic plate 5, thereby keeping the joint axis 12, the connecting end piece 17 and the rope threading tube 18 in position. When the joint movable piece 6 rotates, since the pull rope 20 and the rope threading tube 18 are fixed by the positioning bolt 21, the length is fixed, so the pull rope 20 gradually slides out of the joint movable piece 6 along the rope threading hole 19. At this time, the pull rope 20 pulls the rectangular slider 14 to slide along the rectangular sliding cavity 13 and compresses the reset spring 15. Since the positions of the rectangular slider 14 adjusted by the pressure-adjusting bolts 16 at different fingers are different, the initial compression force of the reset spring 15 of different fingers is different, thereby solving the problem that the traditional method cannot adjust the strength of different fingers.

[0051] In a further preferred embodiment of the present invention, five finger movable mechanisms are provided, and the five finger movable mechanisms are distributed along the outer edge of the palm plate 3 according to the finger arrangement.

[0052] In this embodiment, the finger rehabilitation treatment device is provided with five finger movable mechanisms, which are distributed along the outer edge of the palm plate 3 according to the natural arrangement of the fingers, so that the device can provide rehabilitation training for five fingers at the same time, greatly improving the rehabilitation efficiency. This design allows each finger to receive independent and targeted rehabilitation training. During use, the patient can put his or her fingers into the corresponding finger movable mechanisms respectively, and then adjust the elastic force of each mechanism to adjust the contraction mechanism to set the appropriate rehabilitation strength for each finger.

[0053] In a further preferred embodiment of the present invention, the lifting mechanism includes a rectangular guide column 22, a connecting tube 23, an adjusting nut 24 and a lifting stud 25. The rectangular guide column 22 is slidably installed on the connecting arm plate 2, one end of the rectangular guide column 22 is fixedly connected to the outer surface of the arm sleeve 1, the connecting tube 23 is rotatably installed on the connecting arm plate 2, the connecting tube 23 is arranged parallel to the rectangular guide column 22, the adjusting nut 24 is fixedly installed on one end of the connecting tube 23, the lifting stud 25 is threadedly installed in the adjusting nut 24, and the lifting stud 25 slides through the connecting tube 23 and then the other end is fixedly connected to the outer surface of the arm sleeve 1.

[0054] In this embodiment, the lifting mechanism of the finger rehabilitation therapy device realizes precise height adjustment of the finger rehabilitation part through the cooperation of the rectangular guide column 22, the connecting tube 23, the adjusting nut 24 and the lifting stud 25. First, the rectangular guide column 22 is slidably installed on the connecting arm plate 2, and one end of it is fixedly connected to the outer surface of the arm sleeve 1, ensuring the stability of the arm sleeve 1 during the lifting process. Then, the connecting tube 23 is rotatably installed on the connecting arm plate 2, and is arranged parallel to the rectangular guide column 22, providing a rotation and sliding track for the lifting stud 25. The adjusting nut 24 is fixedly installed at one end of the connecting tube 23, and the lifting stud 25 is threadedly installed in the adjusting nut 24, and one end of it is fixedly connected to the outer surface of the arm sleeve 1 after sliding through the connecting tube 23.

[0055] During use, the user can rotate the adjustment nut 24 to make the adjustment nut 24 slide up and down along the lifting stud 25. At the same time, the adjustment nut 24 drives the connecting tube 23 to rotate, ensuring the connection with the connecting arm plate 2, thereby driving the connecting arm plate 2 and the finger movable mechanism connected thereto to move up and down, and adjusting the distance between the arm sleeve 1 and the arm. Due to the limiting effect of the rectangular guide column 22, the connecting arm plate 2 can maintain stable linear motion during the lifting process, avoiding shaking and deviation. By adjusting the height of the lifting mechanism, the user can easily adjust the finger movable mechanism to the rehabilitation position that best suits him or her, thereby improving the comfort and effectiveness of rehabilitation.

[0056] In a further preferred embodiment of the present invention, the diameter of the arm cuff 1 gradually decreases from the arm to the palm side, the diameter of one side of the arm cuff 1 located on the palm plate 3 is smaller than the other side, and both ends of the arm cuff 1 are expanded outward.

[0057] In this embodiment, the diameter of the arm cuff 1 gradually decreases from the arm to the palm side. This design makes the arm cuff 1 more convenient to wear; both ends of the arm cuff 1 are expanded outward to facilitate insertion during use and protect the user's arm, thereby reducing friction and discomfort between the arm and the device.

[0058] In a further preferred embodiment of the present invention, the inner side of the finger sleeve 9 is a smooth surface, the connecting column 8 is elastic, and at least two connecting columns 8 are provided.

[0059] In this embodiment, the inner side of the finger sleeve 9 of the finger rehabilitation device is a smooth surface, so that the finger can slide easily when it is inserted into the finger sleeve 9, reducing friction and resistance, thereby improving the wearing comfort. At the same time, the connecting column 8, as a bridge between the finger sleeve 9 and the palm plate 3 or other connecting parts, is not only elastic, but also has at least two, which is elastic and convenient for special people and use during insertion, while ensuring the stability and flexibility of the finger sleeve 9 during wearing and use.

[0060] In a further preferred embodiment of the present invention, the side where the telescopic plate 5 is connected to the joint movable piece 6 extends outward and is concave inward respectively, and the telescopic plate 5 and the joint movable piece 6 on one side of the finger sleeve 9 both have curved surfaces for bending.

[0061] In this embodiment, the side where the telescopic plate 5 is connected to the joint movable sheet 6 is designed with an outwardly extending part and an inwardly concave part, respectively. Such a design is intended to better cooperate and ensure that the connection between the two is both stable and flexible. At the same time, the telescopic plate 5 and the joint movable sheet 6 are located on one side of the finger sleeve 9, and both have curved surfaces for bending. Such a design allows the fingers to bend and stretch more naturally during rehabilitation training, thereby simulating real finger movements and improving the rehabilitation effect. When the user is doing rehabilitation training, he only needs to put the finger sleeve 9 on his finger, and by adjusting the telescopic length of the telescopic plate 5, he can achieve precise control of the finger joint movement.

[0062] In a further preferred embodiment of the present invention, the mounting sleeve 4 and the telescopic plate 5 are both rectangular structures, and the palm plate 3 is an arc-shaped plate.

Side sliders 34 are fixedly installed at both ends of the rectangular sliding rod 32, and the side sliders 34 are in sliding contact with both sides of the connecting arm plate 2, further enhancing the stability of the sliding. Synchronous rods 35 are fixedly installed on both side sliders 34, and these synchronous rods 35 extend to the top of the palm plate 3, and an arc-shaped rope threading piece 36 is fixedly installed together. A rope column 37 is fixedly installed on the joint movable piece 6, and a rope threading seat 38 is fixedly installed on the mounting sleeve 4, and the two are located on the same straight line. The arc-shaped rope-threading piece 36 and the rope-threading seat 38 are both provided with rope-threading holes 2 39, and the rope column 37 is fixedly installed with a pull rope 2 40, which passes through the rope-threading holes 2 39 on the arc-shaped rope-threading piece 36 and the rope-threading seat 38. The user can adjust the tension of the pull rope 2 40 by adjusting the positioning bolt 3 41 on the arc-shaped rope-threading piece 36 so that its end contacts the pull rope 2 40. This design allows the user to flexibly adjust the connection tightness between the joint movable piece 6 and the mounting sleeve 4 according to personal needs or training intensity, so as to obtain a better training effect.

[0069] When each finger is bent, the joint movable piece 6 deflects, and the rope column 37 pulls the draw rope 2 40, and the draw rope 2 40 drives the arc-shaped rope-threading piece 36 to slide through the action of the positioning bolt 3 41, and the arc-shaped rope-threading piece 36 drives the synchronization rod 35, the side slider 34 and the rectangular slide bar 32 to slide. At this time, the rectangular slide bar 32 slides along the guide cylinder 31 and compresses the reset spring 2 33, ensuring that the entire finger exerts force synchronously. The reset spring 2 33 is the main force-bearing member, and the reset spring 1 15 is mainly used for fine-tuning. When the finger bends and causes the rectangular slide bar 32 to slide, the reset spring 2 33 will be compressed and store energy. When the finger is relaxed or straightened, the reset spring 2 33 will release the stored energy and push the rectangular slide bar 32 back to the initial position, thereby driving the entire device to return to its initial state;

[0070] Since the arc-shaped rope-threading piece 36 is connected to the joint movable piece 6 of each finger through the synchronization rod 35, when any finger is bent, it will drive the synchronous sliding and resetting of the entire device, thereby ensuring the synchronous force of each finger during the rehabilitation training process, and improving the comprehensiveness and effectiveness of the rehabilitation training.

[0071] In another embodiment of the present invention, a boosting mechanism is provided on the connecting arm plate 2, and the boosting mechanism includes a boosting box 42 fixedly mounted on the connecting arm plate 2, and the same boosting pipe 43 is fixedly mounted on the boosting box 42 and the arm sleeve 1, and the boosting pipe 43 is communicated with the inner cavity of the sac cavity 27 and the boosting box 42, and an air pressure balance hole 44 is opened on the other side of the boosting box 42 corresponding to the boosting pipe 43, and a movable screw 45 is rotatably installed in the boosting box 42, and the movable screw 45 is set in the direction of the boosting pipe 43 and the air pressure balance hole 44, and a piston plate 46 threadedly mounted on the movable screw 45 is slidably installed in the boosting box 42, and a circular gear 47 is fixedly mounted on one end of the movable screw 45, and a meshing drive rack 48 is provided below the circular gear 47, and the drive rack 48 is fixedly connected to the corresponding synchronization rod 35.

[0072] In this embodiment, when in use, the synchronizing rod 35 is fixedly connected to the driving rack 48, so that the bending action of the finger can drive the movement of the driving rack 48. The movement of the driving rack 48 drives the circular gear 47 meshing with it to rotate, and the rotation of the circular gear 47 drives the moving screw 45 to rotate in the booster box 42.

[0073] As the moving screw 45 rotates, the piston plate 46 threaded thereon begins to slide in the boost box 42. This sliding process changes the volume of the inner cavity of the boost box 42, thereby producing a change in air pressure. At the same time, the boost pipe 43 connects the inner cavity of the boost box 42 with the capsule cavity 27 in the arm sleeve 1, so the change in air pressure in the boost box 42 will directly affect the air pressure in the capsule cavity 27. When the piston plate 46 moves toward the boost pipe 43, the volume of the inner cavity of the boost box 42 decreases, the air pressure increases, and then the high-pressure gas is sent into the capsule cavity 27 through the boost pipe 43, so that the arm sleeve 1 wraps the arm more tightly, enhancing the effect and stability of the rehabilitation training. On the contrary, when the piston plate 46 moves toward the air pressure balance hole 44, the volume of the inner cavity of the boost box 42 increases, the air pressure decreases, and the gas in the capsule cavity 27 is discharged through the boost pipe 43, so that the arm sleeve 1 wraps the arm loosely.

[0074] In addition, the arrangement of the air pressure balance hole 44 ensures that the boost box 42 can maintain air pressure balance with the outside world during the movement of the piston plate 46, thereby avoiding safety hazards caused by excessively high or low air pressure. The user can indirectly control the moving distance and speed of the piston plate 46 by controlling the bending degree and speed of the finger, thereby achieving precise adjustment of the air pressure in the capsule cavity 27.

[0075] The design of the booster mechanism enables the finger rehabilitation device to automatically adjust the wrapping tightness of the arm sleeve 1 to the arm according to the bending action of the finger. This design not only improves the flexibility and adaptability of the device, but also enables the user to choose the most suitable wrapping tightness according to personal needs or training intensity. By accurately adjusting the air pressure in the bladder cavity 27, the user can better control the force applied to the arm during rehabilitation training, thereby improving the pertinence and effectiveness of rehabilitation training. The booster mechanism also provides another pressure for weight-bearing training.

[0076] In another embodiment of the present invention, an elastic finger-picking piece 49 is fixedly installed in the finger cot 9. The elastic finger-picking piece 49 is made of elastic material. The elastic finger-picking piece 49 includes a smooth section 50, a front guide section 51, a rear guide section 52 and a finger-picking section 53. The front guide section 51 and the rear guide section 52 are respectively fixedly installed at both ends of the smooth section 50. The finger-picking section 53 is fixedly installed at one end of the front guide section 51 away from the smooth section 50. The finger-picking section 53 is fixedly connected to the bottom inner wall of the finger cot 9, and the rear guide section 52 is in sliding contact with the bottom inner wall of the finger cot 9. The surface of the finger-picking section 53 has anti-slip stripes 54 for finger gripping.

[0077] In this embodiment, an elastic finger pick 49 is added inside the finger sleeve 9, which is located at the finger pad. The elastic finger pick 49 is made of elastic material and has excellent flexibility and durability. It mainly consists of four parts: a smooth section 50, a front guide section 51, a rear guide section 52 and a finger pick section 53.

[0078] When in use, the user inserts a finger into the finger sleeve 9, and the fingertip of the finger first contacts the rear guide section 52. As the finger is further inserted, the fingertip gradually transitions to the finger picking section 53 along the guidance of the smooth section 50 and the front guide section 51.

[0079] The finger gripping section 53 is the core part of the elastic finger gripping sheet 49. It is fixedly mounted on the bottom inner wall of the finger cot 9, corresponding to the finger pad, and is designed with anti-slip stripes 54 to enhance the friction between the finger pad and the finger gripping section 53, so that the finger can be gripped more firmly. When the user needs to bend the finger with force, the finger gripping section 53 can be gripped to provide additional assistance. At the same time, the rear guide section 52 maintains sliding contact with the bottom inner wall of the finger cot 9, ensuring that the finger can move smoothly during the bending process without excessive resistance.

[0080] By designing such an elastic finger-picking piece 49, we provide users with a more comfortable and convenient rehabilitation training experience. Users can pinch the finger-picking section 53 at any time according to their needs to enhance the bending strength of the fingers, thereby performing rehabilitation training more effectively.

[0081] To sum up, compared with related technologies, this device achieves precise control of finger treatment force by introducing an elastic adjustable contraction mechanism, solves the problem of uneven force on different parts of multiple fingers in traditional devices, and can independently adjust the treatment force according to the rehabilitation needs of different fingers, avoiding the situation where local fingers of the hand apply too much or too little force. This not only improves the targetedness and effectiveness of the treatment, but also reduces the discomfort of patients during the treatment process.
