[0002] Stroke, also known as "cerebrovascular accident", is an acute cerebrovascular disease. It is a group of diseases that cause brain tissue damage due to sudden rupture of brain blood vessels or blood vessel blockage that prevents blood from flowing into the brain, including ischemic and hemorrhagic strokes. With the improvement of the living standards of Chinese residents, the changes in people's daily lifestyles, and the accelerated pace of modern work and life, stroke has become a disease with high incidence, high disability rate, and high mortality rate, which seriously endangers human health. Developed countries have conducted extensive research on this disease as early as the 1970s. Although my country started late, it attaches great importance to it. In order to effectively improve the patient's condition and accelerate his recovery so that he can return to his family and society as soon as possible, the Chinese medical community has conducted in-depth research on the rehabilitation treatment of stroke, and has achieved certain results. After rehabilitation training, the identification and measurement of the existing abilities of stroke patients is the stroke rehabilitation assessment.

DETAILED DESCRIPTION

[0043] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figures 1 to 11 A hand rehabilitation assessment device for stroke patients, comprising an arm support 1, a sector plate 2, a hand support 3, an assessment device 1 4, an assessment device 2 5 and an assessment device 3 6. Specifically, the arm support 1 is concave in shape, and a protective layer is embedded in its inner wall. The protective layer is a cushion, which can protect the patient's hand. This design can ensure that the patient's hand is fully protected and supported during the rehabilitation assessment process. The cushion is made of a soft material, which can reduce the pressure and friction on the patient's hand and reduce the risk of discomfort or secondary injury that may occur during the rehabilitation process. A notch 31 corresponding to the two sides is provided on the side of the hand support 3 close to the sector plate 2 to facilitate the user's hand to be placed.

[0045] like Figures 1 to 6As shown, the assessment device 4 is installed on the support arm 1 and the fan-shaped plate 2. The assessment device 4 includes a mounting plate 401, a mounting seat 402 and a slider 403 fixed on the upper and lower sides of the mounting plate 401, and a first piston structure arranged on the fan-shaped plate 2 and connected to the slider 403. A second piston structure used in conjunction with the first piston structure is installed on the outer wall of the support arm 1, and a connecting pipe 407 is fixedly connected between the first piston structure and the second piston structure; a slide groove 21 adapted to the slider 403 is provided inside the fan-shaped plate 2, and the slider 403 is slidably connected to the slide groove 21. The sliding displacement of the slider 403 in the slide groove 21 can accurately reflect the left and right flexibility of the patient's palm. The sliding connection between the slider 403 and the slide groove 21 ensures the accuracy and stability of the evaluation.

[0046] like Figure 3 As shown, a telescopic member is provided between the fan-shaped plate 2 and the hand support 3, wherein the telescopic member is composed of a telescopic rod 411 and a positioning rod 413 which are telescopically connected, an adjustment hole 412 is provided inside the telescopic rod 411, and the positioning rod 413 is plugged into the adjustment hole 412. The fan-shaped plate 2 is located between the support arm 1 and the hand support 3, and its position is lower than the support arm 1 and the hand support 3. This design enables the fan-shaped plate 2 to serve as a transition area, and the position and angle of the hand support 3 can be adjusted in cooperation with the telescopic member according to the different stages and needs of the patient's rehabilitation. In this way, the assessment device can adapt to the process of gradual recovery of the patient's hand function, and provide a more flexible and personalized rehabilitation assessment plan.

[0047] It should be noted that there are multiple adjustment holes 412 on the telescopic rod 411 connected to the handle 3, and the multiple adjustment holes 412 are ring-shaped and are arranged in sequence and equidistantly, so that the two sides of the handle 3 can be alternately replaced and fixed.

[0048] like Figures 3 to 6 As shown, a universal joint 410 is installed on one side of the mounting seat 402 away from the support arm 3, and a fixed shaft 7 fixed to the lower surface of the support arm 1 is installed on the other side of the universal joint 410. Specifically, the first piston structure is composed of a first piston cylinder 404 and a first piston rod 405. The first piston cylinder 404 is fixed in the slide groove 21, one end of the first piston rod 405 extends into the first piston cylinder 404, and the other end thereof is fixed to the outer surface of the slider 403. The second piston structure is composed of a second piston cylinder 406 and a second piston rod 408. The bottom end of the second piston rod 408 extends into the second piston cylinder 406, and the outer surface of the second piston rod 408 is provided with a scale line 4081. The top end of the second piston rod 408 is rotatably installed with an elastic clamp 409. The design of the elastic clamp 409 enables the second piston rod 408 to remain stable when in a fixed position, thereby avoiding evaluation errors or safety issues caused by accidental movement.

[0049] In this embodiment, the connection design between the first piston structure and the second piston structure enables the displacement of the slider 403 to be converted into the lifting and lowering of the second piston rod 408, and then the displacement is accurately read through the scale line 4081 to provide quantitative data for evaluation.

[0050] In this embodiment, Figure 1 , Figure 2 , Figures 7 to 10 As shown, the evaluation device 2 5 includes a fixed structure 501, a wrist strap 502 and a finger ring 503 arranged on the support handle 3, and a mounting rope 504 connected to the fixed structure 501 can be detachably mounted on the finger ring 503; Figure 1 As shown, the hand support 3 is provided with two sides, and the assessment device 25 is provided on one side of the hand support 3, and five tension blocks 8 are fixed on the other side of the hand support 3, and the outer surfaces of the five tension blocks 8 are all sleeved and installed with pads 81, and the fixed structure 501 includes a mounting frame 5011, a clamping ring 5012 and a connecting belt 5013, the clamping ring 5012 is fixed to the mounting frame 5011, one side of the connecting belt 5013 is sleeved with the outer surface of the mounting frame 5011, and the other side of the connecting belt 5013 is sutured and fixed to the wrist strap 502. The fixed structure 501 achieves stable fixation of the wrist strap 502 and the finger ring 503 through the combination of the mounting frame 5011, the clamping ring 5012 and the connecting belt 5013. This design not only ensures the safety of the patient during the assessment process, but also provides sufficient flexibility to adapt to hands of different sizes and shapes.

[0051] like Fig.10 As shown, a limiting ball 5041 is fixed to one end of the installation rope 504 near the installation frame 5011, which is clamped with a clamping ring 5012; an adjusting ring 5042 for adjusting the length is clamped and installed on the outer surface of one end of the installation rope 504 near the limiting ball 5041; and a mounting hole 505 is provided inside the finger ring 503. The limiting ball 5041 and the adjusting ring 5042 on the installation rope 504 allow medical staff to adjust the length of the rope according to the specific conditions of the patient, thereby further ensuring the accuracy of the assessment and the comfort of the patient.

[0052] It should be noted that the design of the wrist strap 502 and the finger ring 503 enables the assessment device 25 to comprehensively assess the flexibility and strength of the patient's wrist and fingers. This is crucial for hand rehabilitation of stroke patients, and helps medical staff understand the patient's rehabilitation progress and develop a personalized rehabilitation plan. In addition, the design of the fixing structure 501 and the installation rope 504 of the assessment device 25 makes the entire device easy to wear and disassemble. This not only facilitates the operation of medical staff, but also improves the user experience of patients.

[0053] like Figure 1 , Figures 9 to 11As shown, the evaluation device 3 6 is arranged on the support handle 3 and used in conjunction with the evaluation device 2 5. The evaluation device 3 6 includes a bottom shell 601, a middle shell 602 and a top shell 603 which are sequentially arranged from bottom to top, and a test structure 604 arranged inside the bottom shell 601. A pointer 605 used in conjunction with the test structure 604 is rotatably mounted on the middle shell 602. The test structure 604 includes a rotating shaft 6041 rotatably mounted at the center of the inner bottom wall of the bottom shell 601, a gear 6042 fixed to the outer surface of the rotating shaft 6041, a connecting seat 6043 slidably arranged inside the bottom shell 601, a rack 6044 fixed to the outer surface of the connecting seat 6043 and connected to the gear 6042, two positioning seats 6045 fixed to the inner bottom wall of the bottom shell 601, and a sleeve rod 6046 fixed between the two positioning seats 6045. A connecting ring 6041 is fixed on one side of the connecting seat 6043. 048, two symmetrically distributed return springs 6047 are hooked and installed between the connecting ring 6048 and the sleeve rod 6046, and a connecting rope 606 extending to the outside of the bottom shell 601 and connected to the finger ring 503 is rotatably installed on the side of the connecting seat 6043 away from the gear 6042; the test structure 604 in the evaluation device three 6 can accurately measure and record the strength and flexibility of the hand during movement through the cooperation of the gear 6042 and the rack 6044, and the sliding of the connecting seat 6043 on the guide rod 6049. This precise evaluation capability helps medical staff to more accurately understand the patient's rehabilitation progress and thus formulate a more effective rehabilitation plan. Among them, a guide rod 6049 that runs through the inside of the connecting seat 6043 is fixedly installed inside the bottom shell 601. The bottom shell 601 can be detachably installed on the hand support 3. The top shell 603 is transparent for patients to observe.

[0054] Specifically, the rotating pointer 605 on the middle shell 602 is used in conjunction with the test structure 604 to provide an intuitive feedback mechanism for medical staff. By observing the indicated position of the pointer 605, medical staff can quickly understand the patient's hand movement without complex calculations or analysis. The connection design of the connecting rope 606 and the finger ring 503 enables the assessment device 36 to dynamically adjust with the movement of the patient's hand. This design not only improves the accuracy of the assessment, but also enables the assessment device to adapt to the rehabilitation needs of different patients, enhancing its versatility and practicality.

[0055] When the present embodiment is in use, the overall design structure of the assessment device three 6 is compact, and the connections between the various components are tight and stable. This design not only improves the accuracy and stability of the assessment, but also makes the maintenance and upkeep of the device during long-term use relatively simple. Medical staff can easily disassemble and reassemble the device to carry out necessary cleaning and disinfection. The synergistic effect with the assessment device two 5 and the coordinated use of the assessment device three 6 and the assessment device two 5 achieve the comprehensiveness and accuracy of the patient's hand rehabilitation assessment. The assessment device two 5 is responsible for fixing and supporting the hand, while the assessment device three 6 is responsible for measuring and recording the data of the hand movement. The two complement each other and together provide strong support for the patient's rehabilitation assessment.

[0056] In summary, the design of using the assessment device 3 6 in conjunction with the assessment device 2 5 brings many benefits, including accurate assessment, intuitive feedback, dynamic assessment and adaptability, the buffering effect of the return spring 6047, compact structure and easy maintenance, and synergy with the assessment device 2 5. These benefits jointly promote the accuracy and efficiency of hand rehabilitation assessment for stroke patients and improve the rehabilitation experience and satisfaction of patients.

[0057] Another technical problem to be solved by the present invention is to provide a method for hand rehabilitation assessment of stroke patients, comprising the following steps:

[0058] 1) First, the patient's arm is supported by the support arm 1, and the support hand 3 is rotated to the side of the tension block 8. The patient spreads his fingers and puts them into the support hand 3. At this time, the left and right flexibility of the patient's palm is tested by the assessment device 4. During the test, the left and right swings of the patient's palm drive the slider 403 to slide in the slide groove 21. When the slider 403 moves, it drives the first piston rod 405 to extend into the first piston cylinder 404 to pump air, and the gas is transported to the second piston cylinder 406 through the connecting pipe 407. At this time, the second piston rod 408 located in the second piston cylinder 406 is lifted by force, and the left and right flexibility of the patient's palm can be assessed through the scale line 4081 on the second piston rod 408;

[0059] After the palm flexibility assessment is completed, the second piston rod 408 is moved downward to allow the elastic clamp 409 to be clamped into the second piston cylinder 406, thereby fixing the assessment device 14;

[0060] When conducting finger rehabilitation test, the hand support 3 is rotated to the other side, and then the wrist strap 502 is fixed on the patient's wrist. This step can realize two sets of test evaluations. First, the palm of the arm faces downward, and the length of the installation rope 504 is adjusted by the adjustment ring 5042. Then the finger ring 503 is put on the patient's finger in turn. At this time, the patient bends his finger and drives the connecting seat 6043 through the connecting rope 606. The displacement of the connecting seat 6043 drives the rotating shaft 6041 through the engagement of the rack 6044 and the gear 6042. The rotating shaft 6041 rotates to drive the pointer 605. By observing the corresponding value of the pointer 605, an evaluation can be performed. When the palm faces upward, this test method can not only test the flexibility of the front and back sides of the palm, but also evaluate and detect the flexibility of the front side of the wrist.

[0061] The assessment device made by this method brings many benefits, such as comprehensive assessment of hand function, personalized test settings, intuitive and easy-to-read assessment results, easy operation and maintenance, improved patient participation, enhanced targeted rehabilitation plans, and promoted doctor-patient communication. These benefits jointly promote the rehabilitation process of patients' hand functions and improve the efficiency and accuracy of rehabilitation assessment.

[0062] The working principle of the above embodiment is:

[0063] When the present invention is used, the patient's arm is first supported by the support arm 1, and the support hand 3 is rotated to one side of the tension block 8. The patient spreads his fingers and puts them into the support hand 3. At this time, the left and right flexibility of the patient's palm is tested by the evaluation device 4. During the test, the left and right swings of the patient's palm drive the slider 403 to slide and move in the slide groove 21. When the slider 403 moves, it drives the first piston rod 405 to extend into the first piston cylinder 404 to pump air, and the gas is transported to the second piston cylinder 406 through the connecting pipe 407. At this time, the second piston rod 408 located in the second piston cylinder 406 is lifted by force, and the left and right flexibility of the patient's palm can be evaluated through the scale line 4081 on the second piston rod 408.

[0064] After the palm flexibility assessment is completed, the second piston rod 408 is moved downward to allow the elastic clamp 409 to be clamped into the second piston cylinder 406, thereby fixing the assessment device 14;

[0065] When conducting finger rehabilitation test, the hand support 3 is rotated to the other side, and then the wrist strap 502 is fixed on the patient's wrist. This step can realize two sets of test evaluations. First, the palm of the arm is facing downward, and the length of the installation rope 504 is adjusted by the adjustment ring 5042. Then, the finger ring 503 is put on the patient's finger in turn. At this time, the patient bends the finger, and the connecting seat 6043 is driven by the connecting rope 606. The displacement of the connecting seat 6043 drives the rotating shaft 6041 through the meshing of the rack 6044 and the gear 6042. The rotating shaft 6041 rotates to drive the pointer 605. By observing the value corresponding to the pointer 605, the evaluation can be performed;
