Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rehabilitation medical equipment, and in particular to a finger-adaptive visual hand rehabilitation trainer. Background Technology
[0002] Hand dysfunction is common in patients with stroke, hand injury, and neurological diseases. The recovery of hand strength and dexterity is crucial for patients' ability to live independently. Therefore, there is a particular need for a finger-adaptive visual hand rehabilitation trainer.
[0003] However, existing hand rehabilitation trainers, such as traditional hand grip strengtheners, can usually only provide a single overall resistance and cannot provide individual training and resistance adjustment for each finger. This makes it difficult to meet the different rehabilitation needs of different fingers. Furthermore, existing rehabilitation trainers lack real-time data monitoring functions and cannot quantify and evaluate training effects.
[0004] To address the aforementioned issues, a search revealed a patent (CN207755706U) disclosed as a finger muscle strength rehabilitation training device. The patent states that "most current devices for finger muscle strength rehabilitation training require users to exert force with their fingers themselves. However, these devices generally do not consider the special circumstances of users requiring finger muscle strength rehabilitation training. For example, some patients with severe finger muscle weakness, after receiving treatment, may experience difficulty using such devices because their finger muscle strength cannot recover quickly, and they require adequate rest. This makes it difficult for them to use the devices effectively, hindering their rehabilitation training." The device also fails to provide a comfortable user experience for patients, thus affecting their experience and the effectiveness of the training. Furthermore, some patients lack awareness of safety precautions during rehabilitation training, leading to secondary injuries due to overexertion. Therefore, this invention provides a finger muscle strength rehabilitation training device to overcome the shortcomings of existing devices. The user can use the reciprocating swing of the arm to drive the fingers to complete the curling and extending training movements. In this way, some more severe patients do not need to use their finger strength to complete the training movements, thus avoiding the inconvenience caused by most existing devices still requiring the patient to use their fingers for training. However, it cannot provide individual training and resistance adjustment for each finger, making it difficult to meet the different rehabilitation needs of different fingers.
[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content
[0006] The purpose of this invention is to provide a finger-adaptive visual hand rehabilitation trainer to solve the problems mentioned in the background art. Traditional hand grip strengtheners can usually only provide a single overall resistance and cannot provide individual training and resistance adjustment for each finger, making it difficult to meet the different rehabilitation needs of different fingers. Secondly, existing rehabilitation trainers lack real-time data monitoring functions and cannot quantify and evaluate the training effect.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a finger-adaptive visual hand rehabilitation trainer, comprising a base, a fixed cylinder fixedly installed at one end of the base, a knob bearing mounted at one end of the fixed cylinder, a screw fixedly connected to the lower end of the knob, a movable cylinder threadedly connected to the outer wall of the screw, a first spring fixedly connected to the upper surface of the movable cylinder, a limit groove formed in the inner wall of the fixed cylinder, a limit block fixedly installed on the outer wall of the movable cylinder, a connecting shell fixedly installed on the upper surface of the knob, a second spring fixedly installed inside the connecting shell, a movable block fixedly connected to the other end of the second spring, a limit rod fixedly connected to one end of the movable block, a first connecting rope fixedly connected to the lower surface of the movable cylinder, a finger sleeve fixedly connected to the other end of the first connecting rope, a finger ring pressure sensor fixedly installed on the inner wall of the finger sleeve, and a second connecting rope fixedly connected to the outer wall of the finger sleeve.
[0008] Preferably, the two ends of the first spring are fixedly connected to the fixed cylinder and the movable cylinder respectively, and the movable cylinder forms a telescopic structure with the fixed cylinder through the first spring.
[0009] Preferably, the limiting block forms a sliding structure with the fixed cylinder through the limiting groove, and a graduated ring is fixedly installed on the outer wall of the fixed cylinder.
[0010] Preferably, the movable block forms a telescopic structure with the connecting shell via a second spring.
[0011] Preferably, the first connecting rope and the second connecting rope are elastic ropes.
[0012] Preferably, the upper surface of the fixed cylinder is provided with limiting holes, which are equally spaced on the upper surface of the fixed cylinder.
[0013] Preferably, the other end of the second connecting rope is fixedly connected to a first magnetic block, a second magnetic block is magnetically connected to one side surface of the first magnetic block, and a guide ball is fixedly connected to one side surface of the second magnetic block.
[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This finger-adaptive visual hand rehabilitation trainer, through the configuration of a base, fixed cylinder, knob, screw, moving cylinder, first spring, limiting groove, limiting block, connecting shell, second spring, moving block, limiting rod, limiting hole, first connecting rope, and finger sleeve, allows for adjustment of resistance to the fingers. Before rehabilitation training, pulling the limiting rod and rotating the knob causes the screw to rotate, and the moving cylinder, threaded to the screw, moves within the fixed cylinder under the limitation of the limiting block. After adjusting the moving cylinder to the appropriate position, releasing the limiting rod causes one end of the limiting rod to engage with the limiting groove, fixing the position of the moving cylinder. This allows for adjustment of the resistance to each finger. The resistance required for each finger can be individually adjusted before training, meeting the needs of different patients and different rehabilitation stages for finger resistance training. Each finger sleeve has a built-in ring pressure sensor, which can collect real-time force data of the fingers during training and transmit the data to a microprocessor. After processing and analyzing the data, the microprocessor transmits the data to a mobile app via Bluetooth or other wireless communication modules. The mobile app receives data from the trainer and generates detailed training reports. These reports include parameters such as the force curve of each finger during each training session, average grip strength, maximum grip strength, training duration, and number of repetitions. Simultaneously, the app can compare and analyze these parameters based on a preset rehabilitation plan and the patient's rehabilitation progress, assess the rehabilitation effect, and provide personalized training suggestions and guidance for adjusting the rehabilitation plan for both patients and medical staff.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 This utility model provides a technical solution: a finger-adaptive visual hand rehabilitation trainer, including a base 1, a fixed cylinder 2 fixedly installed at one end of the base 1, a knob 3 bearing installed at one end of the fixed cylinder 2, a screw 4 fixedly connected to the lower end of the knob 3, a movable cylinder 5 threadedly connected to the outer wall of the screw 4, a first spring 6 fixedly connected to the upper surface of the movable cylinder 5, a limit groove 7 formed on the inner wall of the fixed cylinder 2, a limit block 8 fixedly installed on the outer wall of the movable cylinder 5, and a connecting shell 9 fixedly installed on the upper surface of the knob 3. A second spring 10 is fixedly installed, and a moving block 11 is fixedly connected to the other end of the second spring 10. A limit rod 12 is fixedly connected to one end of the moving block 11. A first connecting rope 14 is fixedly connected to the lower surface of the moving cylinder 5. A finger sleeve 15 is fixedly connected to the other end of the first connecting rope 14. A finger ring pressure sensor 16 is fixedly installed on the inner wall of the finger sleeve 15. A second connecting rope 17 is fixedly connected to the outer wall of the finger sleeve 15. The system is connected to the base 1, fixed cylinder 2, knob 3, screw 4, moving cylinder 5, first spring 6, limit groove 7, limit block 8, and connecting shell 9. The second spring 10, moving block 11, limiting rod 12, limiting hole 13, first connecting rope 14, and finger sleeve 15 are configured such that before rehabilitation training, pulling the limiting rod 12 and rotating the knob 3 will cause the screw 4 to rotate. At this time, the moving cylinder 5, which is threaded to the screw 4, will move in the fixed cylinder 2 under the limitation of the limiting block 8. After adjusting the moving cylinder 5 to the appropriate position, the limiting rod 12 is released. At this time, under the action of the second spring 10, the moving block 11 will take one end of the limiting rod 12 and lock it into the limiting groove 7, which can adjust the position of the moving cylinder 5. The ring is fixed in place, allowing for adjustment of the resistance to the fingers. Before training, the resistance required for each finger can be adjusted individually, meeting the needs of different patients and different stages of rehabilitation for finger resistance training. Secondly, the finger ring pressure sensor 16 can collect the force data of the fingers during training in real time. The opening design of the finger sleeve 15 allows it to be worn on different joints of the fingers. Since the force exertion mode and load of the finger flexor muscles are different when worn on different joints, the strength of different finger flexor muscles can be trained in a targeted manner, achieving a more precise rehabilitation training effect.
[0023] Furthermore, each finger sleeve 15 has an embedded finger ring pressure sensor 16 (range 0-20N) to detect the torque value (N·cm) of each finger when gripping. The calculation formula is: torque = pressure × lever arm (base radius 50mm, the base 1 has an integrated LCD screen fixedly installed on the top, which can display the torque value of the five fingers and the total grip force in real time, and the data is synchronously transmitted to the mobile APP to generate training curves).
[0024] Furthermore, the two ends of the first spring 6 are fixedly connected to the fixed cylinder 2 and the movable cylinder 5 respectively. The movable cylinder 5 forms a telescopic structure with the fixed cylinder 2 through the first spring 6. Through the setting of the first spring 6, the first spring 6 can provide elastic force and resistance.
[0025] Furthermore, the limiting block 8 forms a sliding structure with the fixed cylinder 2 through the limiting groove 7. A scale ring is fixedly installed on the outer wall of the fixed cylinder 2. With the setting of the limiting groove 7 and the limiting block 8, the limiting block 8 will slide in the limiting groove 7 when the moving cylinder 5 moves in the fixed cylinder 2. The limiting block 8 can limit the movement of the moving cylinder 5.
[0026] Furthermore, the movable block 11 forms a telescopic structure with the connecting shell 9 through the second spring 10. With the setting of the second spring 10, when the limiting rod 12 is not under force, the second spring 10 can allow the movable block 11 to carry one end of the limiting rod 12 into the limiting hole 13.
[0027] Furthermore, the first connecting rope 14 and the second connecting rope 17 are elastic ropes. Through the setting of the second connecting rope 17, the second connecting rope 17 can connect the finger ring pressure sensor 16 and the guide ball 20 together, so that the pressure sensor 16 can collect the force data of the finger during the training process in real time.
[0028] Furthermore, a limiting hole 13 is provided on the upper surface of the fixed cylinder 2. The limiting holes 13 are provided at equal intervals on the upper surface of the fixed cylinder 2. By setting the limiting holes 13, the limiting rod 12 can be inserted into the limiting holes 13 at different positions, thereby fixing the moving cylinder 5 in the required position.
[0029] Furthermore, the other end of the second connecting rope 17 is fixedly connected to a first magnetic block 18. A second magnetic block 19 is magnetically connected to one side surface of the first magnetic block 18, and a guide ball 20 is fixedly connected to one side surface of the second magnetic block 19. Through the arrangement of the first magnetic block 18, the second magnetic block 19, and the guide ball 20, the connection between the ring pressure sensor and the guide ball 20 is made possible by the first magnetic block 18 and the second magnetic block 19, which facilitates the replacement of the guide ball 20. During training, the guide ball 20 can be quickly installed through the first magnetic block 18 and the second magnetic block 19. When gripping, pressure needs to be applied to the guide ball 20 to guide the patient to focus on the direction of force and avoid finger deflection. After the guide ball 20 is disassembled, it can be replaced with a guide ball of a different size according to the size of the hand. At the same time, it can also be switched to the regular grip strength training mode.
[0030] Working principle: Before rehabilitation training, pull the limiting rod 12 and turn the knob 3. The knob 3 will rotate the screw 4. At this time, the moving cylinder 5, which is threaded to the screw 4, will move in the fixed cylinder 2 under the limitation of the limiting block 8. After adjusting the moving cylinder 5 to the appropriate position, release the limiting rod 12. At this time, under the action of the second spring 10, the moving block 11 will take one end of the limiting rod 12 and lock it into the limiting groove 7, which can fix the position of the moving cylinder 5. The model of the finger ring pressure sensor 16 is MPX5700.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
