Description

Technical Field

[0001] The present invention relates to the technical field of medical detection, and in particular to a device for evaluating limb function of stroke patients. Background Art

[0002] Stroke, also known as apoplexy or cerebrovascular accident, is a sudden localized brain dysfunction caused by cerebrovascular disease, which usually lasts for more than 24 hours and may even lead to death. The symptoms of stroke vary, depending on the location and extent of the lesion. For example, sudden numbness of the face or hands and feet, temporary slurred speech or difficulty in speaking, limb weakness, difficulty in movement, or even paralysis and other limb function problems.

[0003] In the prior art, an evaluation device is used to evaluate the patient's limb function, so as to determine the incidence and recovery of the patient's stroke; however, the evaluation device in the prior art can only realize a separate motor function evaluation of the patient's arm or leg, but cannot evaluate the arm and leg together, thereby lacking an evaluation of the patient's overall motor coordination, making the evaluation lack of comprehensiveness and accuracy.

[0004] In summary, how to solve the problem that the evaluation device in the prior art can only evaluate the motor function of the patient's arm or leg separately, but cannot evaluate the arm and leg together, thus lacking the evaluation of the patient's overall motor coordination, making the evaluation lack of comprehensiveness and accuracy has become a difficult problem that needs to be solved in the current field. Therefore, it is necessary to propose a more comprehensive limb function evaluation device for stroke patients. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a limb function evaluation device for stroke patients. Through the design of the pedal, the motor function of the patient's lower limbs can be effectively evaluated, and through the design of the rotating disk and the handle, the motor function of the patient's upper limbs can be effectively evaluated. Through the ingenious mechanical structure design, the movement of the patient's lower limbs is associated with the movement of the patient's upper limbs, thereby being able to detect the movement of each part of the patient separately while also detecting the patient's overall limb coordination.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: A limb function assessment device for stroke patients, comprising a base and a seat placed next to the base, a first support plate fixedly connected to the top of the base, a first rotating shaft rotatably engaged with the first support plate, one end of the first rotating shaft is coaxially fixedly connected to a gear ring, and an L-shaped connecting rod is coaxially fixedly connected to the end of the first rotating shaft away from the gear ring; a second support plate is symmetrically fixedly connected to the top of the base, and a second rotating shaft is rotatably engaged with the second support plate; a pedal is fixedly connected to one end of the second rotating shaft, and a gear is coaxially fixedly connected to the other end of the second rotating shaft; the gears are all meshed with the gear ring.

[0007] A bracket is also fixedly connected to the top of the base, and a rotating rod is rotatably cooperated on the bracket. A rotating disk is coaxially fixedly connected to the top of the rotating rod, and a plurality of handles are fixedly connected to the top of the rotating disk; an eccentric wheel is coaxially fixedly connected to the end of the rotating rod away from the rotating disk, a hinged rod is hinged on the eccentric wheel, and the end of the hinged rod away from the rotating disk is hinged to the connecting rod; a monitoring component for monitoring the speed of movement of the rotating disk is provided on the rotating disk; an identification component for facial feature recognition and a driving component for providing power to the first rotating shaft are provided on the bracket.

[0008] The technical principles of the above scheme are as follows:

[0009] The patient places his feet on the pedals, and uses his left foot to step on the left pedal downward, which will cause the left pedal to rotate downward. At the same time, the left gear will rotate counterclockwise, thereby driving the gear ring to rotate counterclockwise, thereby driving the right gear to rotate clockwise, causing the right pedal to rotate upward; at this time, the patient uses his right foot to step on the right pedal downward, which will cause the right pedal to rotate downward, causing the gear ring to change its rotation direction, thereby driving the left gear to change its rotation direction, and at this time the left pedal will rotate upward; this process is repeated to evaluate the limb function of the patient's legs and ankles; at the same time, the reciprocating rotation of the gear ring will drive the connecting rod to swing up and down, thereby causing the articulated rod to drive the eccentric wheel to rotate; the eccentric wheel will drive the rotating disk and the handle to rotate; the patient holds the handle tightly, thereby evaluating the limb function of the patient's arms and hands; conversely, the patient can also use his upper limbs to drive the rotating disk to rotate, thereby driving the pedals to move.

[0010] The patient can also use the driving assembly to drive the first rotating shaft to reciprocate, thereby allowing the pedal and the rotating disk to operate automatically, driving their own limb movements, achieving passive evaluation, and conducting rehabilitation training in this way.

[0011] The above scheme has the following beneficial effects:

[0012] 1. The present invention enables patients to self-assess their lower limbs through the design of the pedals. When assessing the legs, the assessment devices in the prior art can often only assess one side, or move both feet up and down together. Unlike the prior art, the pedals in the present invention can assess both legs of the patient at the same time, and adopt a staggered operation mode, so that the movement of the pedals on both sides is more in line with the normal walking, riding or going up and down stairs posture of the human body, so that the patient can better adapt to the assessment content, thereby producing a better assessment effect. Moreover, the pedals do not simply move up and down, but rotate, so that while bending and stretching the patient's thigh and calf, the patient's ankle is also rotated. According to the bending smoothness of the thigh and calf, the limb function of the patient's thigh and calf can be effectively judged. Combined with the rotation smoothness of the ankle and the fit between the sole of the foot and the pedal, the limb function of the patient's ankle can be effectively judged.

[0013] 2. The present invention enables patients to achieve self-assessment of their upper limbs through the design of a rotating disk and a handle. When evaluating arms, the evaluation devices in the prior art often use lifting equipment to allow the patient to lift both arms upward or bend downward. Unlike the prior art, the present invention adopts the design of a rotating disk and a handle to allow the patient's arms on both sides to reciprocate and straighten and contract. If the patient's left side is straightened, the right side is contracted. When the patient's arms are evaluated, the upper limbs will rotate left and right as the arms on both sides are alternately extended and retracted. Therefore, while the patient's arms are evaluated, the patient's upper limbs can also be evaluated. At the same time, the design of the handle enables the patient's hands to be better gripped, and when the rotating disk rotates, the patient's wrists will rotate in different directions according to the different positions of the handle, thereby achieving the evaluation of the patient's wrists, thereby effectively improving the comprehensiveness of the limb function evaluation.

[0014] 3. The present invention can effectively transmit the force generated by the pedal to the connecting rod and the hinged rod through the design of gears and gear rings, and then drive the rotating disk to rotate through the eccentric wheel and the rotating rod. There is no need to design an additional driving device. Only the patient's own strength is used to simultaneously realize the limb function evaluation of the patient's lower limbs and upper limbs, which can effectively reduce the overall manufacturing cost of the device; the upper limb evaluation is associated with the lower limb evaluation; the patient can perform a separate upper limb evaluation, a separate lower limb evaluation, and a joint evaluation of the upper and lower limbs, thereby meeting the pertinence and comprehensiveness of the evaluation and improving the evaluation experience and evaluation effect.

[0015] Furthermore, the identification component includes a controller and a camera, the camera is fixedly connected to the side wall of the bracket, and the controller is used to control the opening and closing of the camera.

[0016] Beneficial effects: The camera is used to identify the facial features of the patient during the evaluation process. The doctor can analyze the patient's facial features to determine whether the patient has a crooked mouth corner or facial twitching. If so, it means that the patient has a serious stroke. At the same time, the facial expression of the patient during the limb function evaluation can be analyzed to determine whether the patient has difficulty in exerting force, thereby assisting the doctor in judging the patient's limb function.

[0017] Furthermore, one end of the first rotating shaft close to the bracket passes through the bracket and is rotatably matched with the bracket.

[0018] Beneficial effect: When the first rotating shaft rotates, the bracket will provide support for the first rotating shaft, thereby making the rotation of the first rotating shaft more stable, thereby achieving a better transmission effect and improving the coordination of upper limb assessment and lower limb assessment.

[0019] Furthermore, the driving assembly includes a driving member detachably connected to the side wall of the bracket, the output shaft of the driving member is detachably connected to the first rotating shaft passing through one end of the bracket, and the controller is used to control the operation of the driving member, thereby driving the first rotating shaft to reciprocate.

[0020] Beneficial effects: When the patient has difficulty in moving on his own, the driving member can be started through the controller, and the output shaft of the driving member will drive the first rotating shaft to rotate reciprocatingly; thereby, the pedal and the rotating disk can operate autonomously, thereby driving the patient's lower and upper limbs to move, realizing passive evaluation and rehabilitation training functions.

[0021] Furthermore, the monitoring component includes a rotation speed sensor embedded in the rotating disk, and the controller is used to receive the rotation speed value collected by the rotation speed sensor.

[0022] Beneficial effect: When the patient conducts self-assessment, the faster the rotating disk rotates, the greater the speed value collected by the speed sensor. The greater the speed value, the stronger the patient's motor ability and the better the recovery.

[0023] Furthermore, an emergency stop button is embedded in the top of the handle, and the controller is used to receive the emergency stop signal of the emergency stop button, thereby controlling the driving component to shut down.

[0024] Beneficial effects: When the patient wants to stop the passive assessment or rehabilitation training immediately, he can press the emergency stop button to immediately terminate the passive assessment or rehabilitation training, thereby improving the practicality and safety of the device.

[0025] Further, the grip is wavy.

[0026] Beneficial effects: The wavy design allows the handle to better fit the curve of the hand, allowing patients to hold the handle better, thereby optimizing the evaluation results and rehabilitation training effects.

[0027] Furthermore, a protective box for protecting the gears and gear rings is fixedly connected to the top of the base.

[0028] Beneficial effects: The protective box can prevent debris from affecting the operation of the gears and the gear rings, improve the operating stability of the gears and the gear rings, while also preventing patients from being hurt and improving the overall aesthetics of the device.

[0029] Furthermore, straps are fixedly connected to both sides of the pedal.

[0030] Beneficial effects: When patients undergo limb function assessment or rehabilitation training, using straps to bind the patient's feet to the pedals can effectively improve the fit between the patient's feet and the pedals, thereby improving the effectiveness and safety of limb function assessment and rehabilitation training.

[0031] Furthermore, an anti-skid layer is fixedly connected to the surface of the pedal.

[0032] Beneficial effects: The design of the anti-slip layer can increase the friction between the soles of the patients' feet and the pedals, thereby further improving the effect and safety of limb function assessment and rehabilitation training.

[0033] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is further described in detail through specific implementation methods:

[0039] Embodiment 1:

[0040] like Figure 1-Figure 3 As shown, a limb function assessment device for stroke patients includes a base 1 and a seat placed in front of the base 1 (not shown in the figure), a first support plate 2 is fixedly connected with bolts on the top of the base 1, a first rotating shaft 3 is rotatably engaged with the first support plate 2, one end of the first rotating shaft 3 is coaxially bolted with a gear ring 4, and the end of the first rotating shaft 3 away from the gear ring 4 is coaxially bolted with an L-shaped connecting rod 9; a second support plate 5 is symmetrically bolted with bolts on the top of the base 1, and a second rotating shaft 6 is rotatably engaged with the second support plate 5; a pedal 8 is fixedly connected with bolts on one end of the second rotating shaft 6, and a gear 7 is coaxially bolted with the other end of the second rotating shaft 6; the gear 7 is meshed with the gear ring 4.

[0041] A bracket 12 is also bolted to the top of the base 1, and a rotating rod 11 is rotatably mounted on the bracket 12. A rotating disk 13 is coaxially and integrally formed on the top of the rotating rod 11, and a plurality of handles 14 are bolted to the top of the rotating disk 13; an eccentric wheel 16 is coaxially bolted to the end of the rotating rod 11 away from the rotating disk 13, and a hinged rod 10 is hinged to the eccentric wheel 16, and the end of the hinged rod 10 away from the eccentric wheel 16 is hinged to the connecting rod 9; a monitoring component for monitoring the speed of movement of the rotating disk 13 is provided on the rotating disk 13; and an identification component for facial feature recognition and a driving component for providing power to the first rotating shaft 3 are provided on the bracket 12.

[0042] The identification component includes a controller and a camera 15 . The camera 15 is fixedly connected to the side wall of the bracket 12 by bolts. The controller is used to control the opening and closing of the camera 15 .

[0043] like Figure 3 As shown, the right end of the first rotating shaft 3 passes through the bracket 12 and rotates with the bracket 12, so that the first rotating shaft 3 can rotate more stably.

[0044] The driving assembly includes a driving member detachably connected to the side wall of the bracket 12 by bolts, and the output shaft of the driving member is detachably connected to the first rotating shaft 3 passing through one end of the bracket 12 by bolts, and the controller is used to control the operation of the driving member, thereby driving the first rotating shaft 3 to reciprocate. In this embodiment, the driving member is a servo motor 18.

[0045] The monitoring component includes a rotation speed sensor embedded in the rotating disk 13, and the controller is used to receive the rotation speed value collected by the rotation speed sensor.

[0046] The specific implementation process is as follows:

[0047] When performing the self-assessment, first, the patient sits on the chair, places the patient's feet on the pedals 8, and holds the handles 14 tightly with the patient's hands.

[0048] by Figure 1 For example, when the patient uses his left foot to step on the left pedal 8 downward, the left pedal 8 will rotate downward, and the left second shaft 6 will rotate with the rotation of the left pedal 8, thereby driving the left gear 7 to rotate counterclockwise. Since the gear 7 and the gear ring 4 are meshed, the left gear 7 will drive the gear ring 4 to rotate counterclockwise, and the gear ring 4 will then drive the right gear 7 to rotate clockwise, causing the right pedal 8 to rotate upward, thereby lifting the patient's right leg; at this time, the patient uses his right foot to step on the right pedal 8 downward, and the right pedal 8 will rotate downward, causing the gear ring 4 to change its rotation direction, thereby driving the left gear 7 to change its rotation direction, and at this time the left pedal 8 will rotate upward; this is repeated, thereby realizing the evaluation of the patient's leg and ankle limb function.

[0049] At the same time, the reciprocating rotation of the gear ring 4 will drive the first rotating shaft 3 to rotate reciprocally; the first rotating shaft 3 will drive the connecting rod 9 to swing up and down; the L-shaped design of the connecting rod 9 can better be hinged with the articulated rod 10, thereby facilitating the movement of the articulated rod 10; since the two ends of the articulated rod 10 are respectively hinged to the connecting rod 9 and the eccentric wheel 16, the connecting rod 9 will cause the articulated rod 10 to move up and down, and since the rotating rod 11 and the bracket 12 rotate in coordination, the eccentric wheel 16 and the rotating rod 11 are bolted, therefore, the up and down movement of the articulated rod 10 will push and pull the eccentric wheel 16, thereby driving the eccentric wheel 16 to rotate, and the eccentric wheel 16 will drive the rotating rod 11 and the rotating disk 13 to rotate; thereby realizing the evaluation of the limb function of the patient's arm and hand; conversely, the patient can also use the upper limbs to drive the rotating disk 13 to rotate, thereby driving the pedal 8 to move, and then performing the limb function evaluation of the lower limbs.

[0050] During the patient's self-assessment, if the rotating disk 13 rotates faster, the speed value collected by the speed sensor will be larger, and the larger the speed value, the stronger the patient's motor ability and the better the rehabilitation; the controller will transmit the speed value of the rotating disk 13 to the patient's and the doctor's mobile phones, so that the patient and the doctor can understand the patient's limb function and rehabilitation through the speed value of the rotating disk 13. And because the pedal 8 swings up and down once, the gear ring 4 rotates back and forth for a cycle, so that the connecting rod 9 swings up and down once, and the rotating disk 13 rotates one circle; therefore, whether only upper limb training or lower limb training is performed, the patient's limb function and rehabilitation can be understood through the speed value of the rotating disk 13.

[0051] When the patient has difficulty in moving on his own, the servo motor 18 can also be started through the controller. The output shaft of the servo motor 18 will drive the first rotating shaft 3 to rotate back and forth, so that the pedal 8 and the rotating disk 13 can operate autonomously, thereby driving the patient's lower limbs and upper limbs to move, realizing passive evaluation and rehabilitation training functions.

[0052] During the patient's limb function assessment and rehabilitation training, the camera 15 collects the patient's facial feature images during the assessment process and transmits them to the doctor's mobile phone through the controller. The doctor analyzes the patient's facial feature images to determine whether the patient has crooked mouth corners and facial twitching. If so, it means that the patient's stroke is more serious and requires further examination and treatment. At the same time, the doctor can also analyze the patient's facial expressions during the limb function assessment to determine whether the patient has difficulty in exerting force, thereby assisting the doctor in judging the patient's limb function. If the patient's facial expression is relaxed, it is judged that the patient has smooth force and good limb function; otherwise, it is judged that the patient has difficulty exerting force and poor limb function.

[0053] Through the design of the pedal 8, the patient can realize self-assessment of the lower limbs; when the assessment device in the prior art assesses the legs, it can often only assess one side, or move both feet up and down together. Unlike the prior art, the pedal 8 in this embodiment can assess both legs of the patient at the same time, and adopts a staggered operation mode, so that the movement of the pedals 8 on both sides is more in line with the normal posture of human body walking, riding or going up and down stairs, so that the patient can better adapt to the assessment content, thereby producing a better assessment effect. Moreover, the pedal 8 does not simply move up and down, but rotates, so that the patient can bend and stretch the thigh and calf while rotating his own ankle. According to the bending smoothness of the thigh and calf, the limb function of the patient's thigh and calf can be effectively judged, and combined with the rotation smoothness of the ankle and the fit between the sole of the foot and the pedal 8, the limb function of the patient's ankle can be effectively judged.

[0054] Through the design of the rotating disk 13 and the handle 14, the patient can achieve self-assessment of the upper limbs; when the assessment device in the prior art assesses the arms, it often uses a lifting device to make the patient lift both arms upward or bend downward together. Different from the prior art, the present embodiment adopts the design of the rotating disk 13 and the handle 14, so that the patient's arms on both sides can be reciprocatedly extended, contracted and swung left and right, and if the patient's left arm is straightened, the right arm is contracted, so that while the patient is assessing his arms, the patient's shoulders and waist will rotate left and right as the arms on both sides are alternately extended and retracted back and forth, so that while the patient's arms are being assessed, the patient's upper limbs can also be assessed. At the same time, the design of the handle 14 enables the patient's hands to be better gripped, and when the rotating disk 13 rotates, the patient's wrists will rotate in different directions depending on the position of the handle 14, thereby achieving the assessment of the patient's wrists, thereby effectively improving the comprehensiveness of the limb function assessment.

[0055] Through the design of the gear 7 and the gear ring 4, the force generated by the pedal 8 can be effectively transmitted to the connecting rod 9 and the hinged rod 10, and then through the transmission of the eccentric wheel 16 and the rotating rod 11, the rotating disk 13 can be driven to rotate. There is no need to design an additional driving device. Only the patient's own strength can be used to simultaneously realize the limb function evaluation of the patient's lower limbs and upper limbs, which can effectively reduce the overall manufacturing cost of the device; the upper limb evaluation is associated with the lower limb evaluation; the patient can perform a separate upper limb evaluation, a separate lower limb evaluation, and a joint evaluation of the upper and lower limbs, and can also only perform an evaluation of one side of the arm or leg, thereby meeting the targeted and comprehensive nature of the evaluation and improving the evaluation experience and evaluation effect.

[0056] Embodiment 2:

[0057] like Figure 2 and Figure 3As shown, different from the above-mentioned embodiment, an emergency stop button is embedded in the top of the handle 14, and the controller is used to receive the emergency stop signal of the emergency stop button, and then control the driving member to close.

[0058] The specific implementation process is as follows: when the patient wants to stop passive assessment or rehabilitation training immediately, he can press the emergency stop button to immediately terminate the limb function assessment or rehabilitation training, thereby improving the practicality and safety of the device.

[0059] Embodiment 3:

[0060] like Figure 2 and Figure 3 As shown, different from the above-mentioned embodiment, the handle 14 is wavy.

[0061] The specific implementation process is as follows: The wavy design enables the handle 14 to better fit the curve of the hand, allowing the patient to better hold the handle 14, thereby optimizing the evaluation effect and rehabilitation training effect.

[0062] Embodiment 4:

[0063] like Figure 3 As shown, different from the above-mentioned embodiment, a protection box 17 for protecting the gear 7 and the gear ring 4 is also bolted and fixedly connected to the top of the base 1 .

[0064] The specific implementation process is as follows: the protection box 17 can prevent debris from affecting the operation of the gear 7 and the gear ring 4, improve the operating stability of the gear 7 and the gear ring 4, while also avoiding harm to the patient and improving the overall aesthetics of the device.

[0065] Embodiment 5:

[0066] like Figure 3 As shown, different from the above-mentioned embodiment, both sides of the pedal 8 are fixedly bonded with straps.

[0067] The specific implementation process is as follows: when the patient undergoes limb function assessment or rehabilitation training, the patient's foot is bound to the pedal 8 using a strap, which can effectively improve the fit between the patient's foot and the pedal 8, and improve the effect and safety of the limb function assessment and rehabilitation training.

[0068] Example 6

[0069] like Figure 1 As shown, different from the above-mentioned embodiment, a non-slip layer is fixedly bonded to the surface of the pedal 8 .

[0070] The specific implementation process is as follows: The design of the anti-slip layer can increase the friction between the sole of the patient's foot and the pedal 8, thereby further improving the effect and safety of limb function assessment and rehabilitation training.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
