Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation training device technology, and in particular relates to a finger rehabilitation training device for stroke patients. Background Technology

[0002] Stroke, a serious cerebrovascular disease that severely endangers human health, often leaves stroke patients with varying degrees of limb dysfunction after their condition stabilizes. Finger dysfunction is particularly common and significantly impacts patients' daily lives. Dexterous finger movement is fundamental for fine motor skills such as grasping and pinching; therefore, helping stroke patients restore finger function is a crucial aspect of rehabilitation therapy.

[0003] Currently, there are many types of equipment available for finger rehabilitation training in clinical practice for stroke patients, such as simple grip balls and grip rings. However, these traditional training devices have several limitations. Grip balls and grip rings provide relatively uniform resistance, making it impossible to flexibly adjust the training intensity according to different rehabilitation stages and individual differences. For patients in the early stages of rehabilitation with weak finger strength, excessive resistance may prevent training from proceeding smoothly or even cause secondary injury; while for patients in the later stages of rehabilitation with some recovery in finger strength, the fixed resistance is insufficient to meet the needs of further intensive training.

[0004] Therefore, developing a finger rehabilitation trainer for stroke patients that can provide finger grip strength training at different intensities and has a scientifically sound resistance adjustment mechanism is of significant practical importance and application value for improving the targeting and effectiveness of finger rehabilitation training for stroke patients. To this end, we provide a finger rehabilitation trainer for stroke patients to address the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a finger rehabilitation trainer for stroke patients. By combining the training component and the resistance adjustment component, it solves the problem that existing rehabilitation trainers have a single resistance and cannot flexibly adjust the training intensity according to the different rehabilitation stages and individual differences of patients.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a finger rehabilitation training device for stroke patients, comprising a training component and a resistance adjustment component. The resistance adjustment component is fixedly connected to the inner cavity of the training component. The training component includes a vertical tube, with support plates fixedly connected to both its upper and lower ends. A movable plate is slidably connected between the upper and lower support plates. A spring is fixedly connected to the inner wall of the movable plate, and the other end of the spring is fixedly connected to the surface of the resistance adjustment component. A rubber sleeve is fitted onto the surface of the movable plate, with both its upper and lower ends fixedly connected to the support plates. The resistance adjustment component includes a drive shaft disposed within the inner cavity of the vertical tube. The bottom of the drive shaft is fixedly connected to the support plate via a bearing. A driving bevel gear is fixedly connected to the surface of the drive shaft, and a driven bevel gear meshes with the surface of the driving bevel gear. A lead screw is fixedly connected to the surface of the driven bevel gear, and a threaded tube is threaded onto the surface of the lead screw. The other end of the threaded tube extends through to the outside of the vertical tube and is fixedly connected to a connecting plate. The surface of the connecting plate is fixedly connected to the other end of the spring.

[0008] The present invention is further provided that a throttle is fixedly connected to the top of the transmission shaft, and the surface of the throttle is provided with anti-slip texture. The throttle makes it convenient for users to operate, and the anti-slip texture on the surface increases the friction when gripping, preventing the hand from slipping during the adjustment of resistance, and improving the convenience and stability of operation.

[0009] The present invention is further configured such that the surface of the rubber sleeve is provided with anti-slip ridges, and the top of the support plate is provided with a circular hole for the transmission shaft to pass through. The anti-slip ridges further enhance the friction when the fingers grip the sleeve, preventing the hand from slipping during training. The circular hole in the top support plate provides space for the transmission shaft to pass through, ensuring its normal rotation.

[0010] The present invention is further configured such that a through hole for the spiral tube is opened on the surface of the vertical tube, and limit holes are opened at both the upper and lower ends of the through hole. The through hole provides a moving channel for the spiral tube, and the limit holes at the upper and lower ends cooperate with the limit rod to restrict the movement direction of the spiral tube, prevent it from deviating or rotating during movement, and ensure the accuracy of resistance adjustment.

[0011] The present invention is further configured such that a limiting rod is provided in the inner cavity of the limiting hole, and the other end of the limiting rod is fixedly connected to the surface of the screw tube. The limiting rod slides in the limiting hole and is fixedly connected to the screw tube, playing a guiding and limiting role, ensuring that the screw tube moves smoothly along a straight line, and making the resistance adjustment process more stable and reliable.

[0012] The present invention is further configured such that a bearing is fixedly connected to the surface of the lead screw, and the surface of the bearing is fixedly connected to the inner wall of the vertical pipe through a bearing seat. The bearing seat is installed on the inner wall of the vertical pipe, which on the one hand provides support for the lead screw, making its rotation smoother, and on the other hand reduces friction when the lead screw rotates, thereby improving transmission efficiency.

[0013] The present invention is further configured such that sliders are fixedly connected to the top and bottom of the movable plate, and grooves are provided on the opposite side of the upper and lower support plates. The end of the slider away from the movable plate extends into the inner cavity of the groove and is slidably connected to the inner cavity of the groove. The slider and the groove cooperate to restrict the movement direction of the movable plate, so that it can only slide in the vertical direction, thereby enhancing the stability of the movable plate when it moves and ensuring the smoothness of the training process.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model can flexibly adjust the intensity of finger grip strength training according to the physical condition and individual differences of stroke patients at different stages of rehabilitation. In the early stage of rehabilitation, the resistance can be adjusted to a low level to avoid training difficulties or secondary injuries to patients with weak finger strength due to excessive resistance, thus ensuring training safety. As the rehabilitation process progresses and the patient's finger strength increases, the resistance can be gradually increased to meet the needs of further intensive training, realizing systematic training from basic recovery to functional improvement, and significantly improving the pertinence and effectiveness of rehabilitation training.

[0016] 2. The vertical tube and upper and lower support plates of this utility model form a stable frame. The sliding connection design of the movable plate in between, combined with the elasticity of the spring, provides stable support for finger training. The resistance adjustment component converts the rotation of the handle into the linear movement of the screw tube through the transmission of components such as the transmission shaft, bevel gear set and lead screw, thereby adjusting the spring tension to change the resistance. The whole process is simple to operate. Patients or medical staff only need to turn the handle to complete the resistance adjustment. No complicated operation is required, which is convenient for daily training. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figure 1-5 This utility model relates to a finger rehabilitation training device for stroke patients, comprising a training component 1 and a resistance adjustment component 2. The resistance adjustment component 2 is fixedly connected to the inner cavity of the training component 1. The training component 1 includes a vertical tube 11, with support plates 12 fixedly connected to both the upper and lower ends of the vertical tube 11. A movable plate 13 is slidably connected between the upper and lower support plates 12. A spring 14 is fixedly connected to the inner wall of the movable plate 13, and the other end of the spring 14 is fixedly connected to the surface of the resistance adjustment component 2. A rubber sleeve 15 is fitted onto the surface of the movable plate 13, with both the upper and lower ends of the rubber sleeve 15 connected to the support plates 12. The plate 12 is fixedly connected. The resistance adjustment assembly 2 includes a drive shaft 21 disposed in the inner cavity of the vertical tube 11. The bottom of the drive shaft 21 is fixedly connected to the support plate 12 through a bearing. A driving bevel gear 22 is fixedly connected to the surface of the drive shaft 21. A driven bevel gear 23 meshes with the surface of the driving bevel gear 22. A lead screw 24 is fixedly connected to the surface of the driven bevel gear 23. A screw tube 25 is threadedly connected to the surface of the lead screw 24. The other end of the screw tube 25 extends through to the outside of the vertical tube 11 and is fixedly connected to a connecting plate 26. The surface of the connecting plate 26 is fixedly connected to the other end of the spring 14.

[0027] Specifically: The vertical tube 11 is set vertically to provide stable longitudinal support for the overall structure. The two support plates 12 are parallel to each other, forming a stable frame structure. The movable plate 13 set between the upper and lower support plates 12 can slide vertically between them. Its sliding connection allows the movable plate 13 to move flexibly when subjected to external force. The elastic characteristics of the spring 14 are one of the key components for realizing the change of training resistance. The other end of the spring 14 is fixedly connected to the surface of the resistance adjustment component 2, thereby establishing a linkage relationship between the training component 1 and the resistance adjustment component 2. The rubber sleeve 15 is soft and has good friction, which not only provides a comfortable grip for the patient's fingers, but also has both ends fixedly connected to the support plate 12, further enhancing the stability and sealing of the overall structure. In the resistance adjustment component 2, when the lead screw 24 rotates, the screw tube 25 will move linearly along the axis of the lead screw 24 under the cooperation of the driving bevel gear 22 and the driven bevel gear 23. The connecting plate 26 transmits the linear movement of the screw tube 25 to the spring 14, thereby realizing the adjustment of the tension of the spring 14 and achieving the purpose of changing the training resistance.

[0028] Example 2

[0029] Please see Figure 1-5 Based on Embodiment 1, a throttle 27 is fixedly connected to the top of the drive shaft 21. The surface of the throttle 27 is provided with anti-slip texture. The surface of the rubber sleeve 15 is provided with anti-slip ridges. The top of the support plate 12 located at the top is provided with a round hole through the drive shaft 21. The surface of the vertical tube 11 is provided with a through hole 16 through the screw tube 25. Limiting holes 17 are provided at both the upper and lower ends of the through hole 16. A limiting rod 28 is provided in the inner cavity of the limiting hole 17. The other end of the limiting rod 28 is fixedly connected to the surface of the screw tube 25. A bearing is fixedly connected to the surface of the lead screw 24. The surface of the bearing is fixedly connected to the inner wall of the vertical tube 11 through the bearing seat. A slider 18 is fixedly connected to the top and bottom of the movable plate 13. A sliding groove 19 is provided on the opposite side of the upper and lower support plates 12. The end of the slider 18 away from the movable plate 13 extends into the inner cavity of the sliding groove 19 and slides in connection with the inner cavity of the sliding groove 19.

[0030] Specifically: the throttle 27 facilitates user operation; the anti-slip texture on the surface increases friction during grip, preventing slippage during resistance adjustment and improving operational convenience and stability; the anti-slip ridges further enhance finger grip friction, preventing hand slippage during training; the round hole in the top support plate 12 provides passage for the drive shaft 21, ensuring its normal rotation; the through hole 16 provides a movement channel for the solenoid 25; the limiting holes 17 at the upper and lower ends cooperate with the limiting rod 28 to restrict the movement direction of the solenoid 25, preventing it from shifting or rotating during movement and ensuring resistance. To ensure the accuracy of force adjustment, the limiting rod 28 slides within the limiting hole 17 and is fixedly connected to the solenoid 25, serving as a guide and limiting element. This ensures that the solenoid 25 moves smoothly along a straight line, making the resistance adjustment process more stable and reliable. The bearing seat is installed on the inner wall of the vertical tube 11, providing support for the lead screw 24 to make its rotation smoother, and reducing friction during the rotation of the lead screw 24 to improve transmission efficiency. The slider 18 cooperates with the slide groove 19 to restrict the movement direction of the movable plate 13, allowing it to slide only in the vertical direction, enhancing the stability of the movable plate 13 during movement, and ensuring the smoothness of the training process.

[0031] The working principle of this utility model is as follows: The user rotates the handle 27 at the top of the transmission shaft 21, causing the transmission shaft 21 to rotate, which in turn causes the active bevel gear 22 fixed on the transmission shaft 21 to rotate. The active bevel gear 22 meshes with the driven bevel gear 23, transmitting power to the driven bevel gear 23. The driven bevel gear 23 drives the lead screw 24 to rotate. Since the lead screw 24 is threadedly connected to the screw tube 25, the rotation of the lead screw 24 is converted into linear movement of the screw tube 25 along the axis of the lead screw 24. The screw tube 25 pulls the spring 14 through the connecting plate 26, changing the degree of tension of the spring 14, thereby adjusting the training resistance. When the patient performs finger rehabilitation training, he holds the rubber sleeve 15 on the movable plate 13 and applies gripping force to make the movable plate 13 slide between the upper and lower support plates 12 inside the vertical tube 11. The spring 14 provides corresponding resistance to achieve the purpose of exercising finger strength.

[0032] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
