Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training. More specifically, the present invention relates to a wrist function trainer and a wrist training method. Background Art

[0002] A wrist function trainer is an apparatus composed of a group of cylinders of different sizes with grips on one or both sides (as shown in Figure 1 ). The surface of the cylinder is wrapped with a sticky nylon belt. The patient can hold the grip and roll the cylinder back and forth on the plane covered with the sticky nylon belt, which is mainly used for training the muscle strength of the wrist flexion and extension muscle groups and the range of joint motion.

[0003] However, the adhesive substance of the existing wrist function trainer is easy to get dirty and not easy to clean and replace. Moreover, the adhesive force is fixed, which is not friendly to individual differences, resulting in poor rehabilitation training effect. In addition, the viscosity of the wrist function trainer used for a long time may decrease, further reducing the training effect. Summary of the Invention

[0004] To solve the above technical problem of the poor rehabilitation training effect of the existing wrist function trainer, the present invention provides solutions in the following aspects.

[0005] In a first aspect, the present invention provides a wrist function trainer, including: a training platform and a training component, there is a magnetic force action between the training platform and the training component to enable a user to perform wrist training on the training platform using the training component; a control module is built in the training platform, and the control module is used to control the magnitude of the magnetic force; and a sensor installed on the training platform, the sensor is connected to the control module and is used to collect training data during the user's training process.

[0006] Further, the training component includes a rolling component and a lifting component, the sensor includes a displacement sensor and a distance sensor, and an electromagnet module is also built in the training platform, and the electromagnet module is connected to the control module.

[0007] Further, the wrist function trainer further includes a display screen, and the display screen is communicatively connected to the control module and is used to display the user's training results.

[0008] In a second aspect, the present invention provides a wrist training method based on the wrist function trainer described in the first aspect, including: determining an initial magnetic force or an initial gear for the user's training according to the input information; obtaining training data during the user's training process, the training data including the number of training times and the training distance; and in response to the training data meeting a preset condition, adjusting the initial magnetic force or the initial gear.

[0009] Further, in response to the training data satisfying a preset condition, adjusting the initial magnetic force or the initial gear position includes: in response to reaching a preset number of training times, and a preset ratio of the training distances corresponding to the preset number of training times being greater than a preset training distance, increasing the training gear position or increasing the initial magnetic force to a specified value.

[0010] Further, the preset number of training times, the preset ratio, and the preset training distance are fixed values or determined by historical training data.

[0011] Further, determining the initial magnetic force or the initial gear position for the user's training according to the input information includes: determining the initial magnetic force or the initial gear position according to the input training method and training gear position.

[0012] Further, it further includes: in response to the user completing the training, outputting a training result, where the training result includes a training method, a training gear position, and a training distance.

And during the training process, the training gear position or magnetic force can be further adjusted according to the actual wrist condition of the user, further improving the rehabilitation effect and safety of wrist training. Further, since the wrist function trainer of the present invention can adjust the magnitude of the magnetic force, it avoids the problem of decreased adhesion caused by long-term use of the existing wrist function trainer, improving the service life and training effect of the wrist function trainer; in addition, the wrist function trainer of the present invention is also easy to clean and manage, and has stronger versatility.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0025] Next, the specific implementation manners of the present invention will be described in detail with reference to the accompanying drawings.

[0026] Figure 2 schematically shows a wrist function trainer according to an embodiment of the present invention.

[0027] In a first aspect, the present invention provides a wrist function trainer, as Figure 2 shown, the wrist function trainer of the present invention includes a training platform and a training component, and there is a magnetic force between the training platform and the training component to enable a user to perform wrist function training on the training platform by using the training component.

[0028] Specifically, an electromagnet module is provided on the training tabletop of the training platform. Sensors are distributed above the training tabletop, and a control module is provided below the training tabletop. Among them, both the electromagnet module and the sensors are connected to the control module. Specifically, the control module is used to output currents of different magnitudes, thereby controlling the magnitude of the magnetic force output by the electromagnet module; a layer of magnet is provided outside the training component, so as to match with the electromagnet module to generate a magnetic force effect, so that the user can use the training component to perform wrist training on the training platform; the sensors are used to collect the training data of the user, so as to adjust the training gear or the magnitude of the magnetic force of the user during training according to the training data.

[0029] In this embodiment, the training component includes a lifting component and a rolling component. Among them, the lifting component corresponds to the lifting training in the training method, and the rolling component corresponds to the rolling training in the training method. Further, the sensors include a displacement sensor and a distance sensor. Among them, the displacement sensor is used to collect the distances (including the leftmost distance, the rightmost distance, and the total rolling distance) of the user during rolling training, and the distance sensor is used to collect the height of the user during lifting training. In an alternative embodiment, an angle sensor may also be included to detect the angle change during rolling training.

[0030] By controlling the magnitude of the magnetic force between the training platform and the training component, different magnetic forces can be set for different users. For example, a larger magnetic force is set for users with better wrist functions, and correspondingly, a smaller magnetic force is set for users with poorer wrist functions, solving the problem that the existing wrist function trainer has a fixed adhesion and does not have targeted training, enabling users to obtain effective wrist training, thereby improving the effect of users' wrist training. Further, due to the use of magnetic force, compared with the sticky nylon belt, the wrist function trainer of the present invention is easier to clean, and the magnetic force will not change due to the service life. Even if it changes, it can be adjusted through the electromagnet module, ensuring the training effect and extending the service life of the wrist function trainer. Further, the present invention adjusts the current training gear or magnetic force of the user according to the training data during the user's training. Since the training data can truly reflect the actual situation of the user's wrist, therefore, by adjusting the current training gear or training magnetic force according to the actual situation of the user, the user can perform more effective wrist training, while ensuring the safety of the user and improving the training effect of the user.

[0031] In one embodiment, the wrist function trainer of the present invention further includes a display screen, which is connected to the control module and is used to display the training results of the user. By displaying the training results of the user, the training achievements of the user can be intuitively and clearly understood, so as to adjust or make suggestions for the next wrist training.

[0032] In one embodiment, both the lifting training and the rolling training of the wrist function trainer of the present invention have 5 gears. Specifically, the first gear of the lifting training is 1 kg (lifting force), the second gear is 2 kg, the third gear is 3 kg, the fourth gear is 4 kg, and the fifth gear is 5 kg; the first gear of the rolling training is 0.5 kg, the second gear is 1 kg, the third gear is 1.5 kg, the fourth gear is 2 kg, and the fifth gear is 2.5 kg; in an alternative embodiment, the number of gears and the corresponding forces can be set according to actual needs. In addition, more accurate and higher-precision magnetic force values can also be directly set, and those skilled in the art can make such settings according to actual needs.

[0033] In one embodiment, the wrist function trainer of the present invention further includes a storage box (as Figure 3 shown) for storing various training components to facilitate management and storage and prevent loss.

[0034] Specifically, during the rolling training, the position of the rolling component is initialized (the rolling component is placed at a preset initial position), and then the user uses the rolling component for training. The data of each rolling training is recorded, that is, the left rolling distance G1 is recorded when the rolling component turns left, and the right rolling distance G2 is recorded when it turns right. The total rolling distance L (L = 2 * G1 + 2 * G2) is calculated.

[0035] Further, during the wrist training, the position of the lifting component is initialized (the rolling component is placed at a preset initial position), and then the user uses the lifting component for training. The data of each lifting training, namely the lifting height and the number of lifts, is recorded.

[0036] Figure 4 Schematically shows a wrist training method according to an embodiment of the present invention.

[0037] In a second aspect, the present invention provides a wrist training method for the above-mentioned wrist function trainer, as Figure 4 shown. The method of the present invention includes:

[0038] S101. Determine the initial magnetic force or the initial gear for the user's training according to the input information.

[0039] In one embodiment, the initial gear or the initial magnetic force can be determined according to the input training method and training gear. Among them, the training methods include lifting training and rolling training. Different training methods use different training components and have different focuses on wrist training, all of which need to be selected according to the actual situation of the user. In addition, the training gear can be preliminarily determined according to the actual situation of the user (it can be determined by a rehabilitation therapist). In an alternative embodiment, the corresponding initial gear or magnetic force can also be directly matched according to the personal situation of the user.

[0040] S102. Obtain the training data during the user's training process.

[0041] In one embodiment, the training data includes the number of training sessions and the training distance. Among them, the training distance includes at least one of the lifting height, the leftmost distance, the rightmost distance, and the total rolling distance.

[0042] Specifically, if it is a lifting training, the training data may include the number of training sessions (i.e., the number of times leaving the training platform) and the lifting height. The lifting height can be collected by a distance sensor. Among them, the lifting distance reflects the strength of the user's wrist, and the number of lifts reflects the intensity of the lifting training. If it is a rolling training, the training data may include the number of training sessions (rolling once when reaching the initial position 2 times), the leftmost distance (the distance rolled to the leftmost side), the rightmost distance (the distance rolled to the rightmost side), and the total rolling distance (L = 2*G1 + 2*G2, where G1 is the left rolling distance and G2 is the right rolling distance), which can be collected by a displacement sensor. Among them, the leftmost distance and the rightmost distance reflect the twisting of the user's wrist, and the total rolling distance and / or the number of training sessions reflect the intensity of the rolling training.

[0043] S103. In response to the training data satisfying a preset condition, adjust the initial magnetic force or the initial gear.

[0044] In this embodiment, when the user reaches the preset number of training sessions at the current gear or magnetic force, and a preset proportion of the training distances corresponding to the preset number of training sessions are all greater than the preset training distance, increase the training gear or increase the initial magnetic force to a specified value;

[0045] Specifically, when the user performs lifting training, if the user has trained for the preset number of times at the current gear or magnetic force, and among the lifting heights corresponding to these preset number of times, a preset proportion of the heights are all greater than the preset height, increase one training gear or increase the magnetic force, and the user performs lifting training according to the adjusted gear or magnetic force. The above parameters can be fixed values or determined by historical training data. In this embodiment, the preset number of times is 20 times, the preset proportion is 90%, and the preset height is 12 cm. In an alternative embodiment, those skilled in the art can set these parameters according to actual needs.

[0046] To make this application clearer, the above parameters are used for illustration. For example, if a user has trained 20 times in gear 1, and if the lifting height in 19 out of these 20 times is greater than 12 cm, then the user will train in gear 2. It can be understood that if a user has trained 20 times in the current gear or with magnetic force, and most of the lifting distances are relatively high (reaching the preset lifting distance), it indicates that the user has relatively good wrist strength. If the user continues to train with the magnetic force corresponding to the current gear, the training intensity at this time will not achieve an ideal effect for the user. Therefore, by increasing the training gear or magnetic force, the training intensity of the user is increased, so that the user can conduct more effective training, thereby improving the training effect.

[0047] In an alternative embodiment, if a user has trained 20 times in the current gear, and most of the lifting heights do not reach the preset distance (e.g., 6 cm), or if the user has trained less than 10 times and the lifting heights are all relatively low (less than 6 cm), it indicates that the training intensity of the current gear is relatively high for the user, that is, the current gear exceeds the user's ability to continuously conduct wrist training (the initial gear setting is too high). At this time, the gear should be lowered by one level or the magnetic force should be reduced to avoid the adverse effects brought by the user continuously training with a gear or magnetic force that exceeds their own ability (that is, not only will the training not achieve the desired effect, but it may also cause problems such as muscle damage). By adjusting the user's training gear or magnetic force according to the actual situation of the user, the training safety and training effect of the user can be ensured.

[0048] In one embodiment, when a user conducts rolling training, if the user has trained a preset number of times in the current gear or with magnetic force, and among these preset number of times, the leftmost distance and the rightmost distance corresponding to a preset proportion of the times are both greater than the preset distance, then the training gear is increased by one level or the magnetic force is increased, and the user conducts rolling training according to the adjusted gear or magnetic force. In this embodiment, the preset number of times is 20 times, the preset proportion is 90%, and the preset distance is 6 cm. In alternative embodiments, those skilled in the art can set these parameters according to actual needs.

[0049] To make this application clearer, the above parameters are used for illustration. For example, if a user has trained 20 times in gear 1, and if the leftmost distance in 19 out of these 20 times of training is greater than 6 cm, and the rightmost distance is also greater than 6 cm, then the user will conduct rolling training in gear 2. It can be understood that if a user has trained 20 times in the current gear, and most of the distances are relatively high (reaching the preset rolling distance), it indicates that the user has relatively good wrist twisting ability. If the user continues to train with the magnetic force corresponding to the current gear, the training intensity at this time will not achieve a very good effect for the user. Therefore, by increasing the training gear or magnetic force, the training intensity of the user is increased, so that the user can conduct more effective training, thereby improving the training effect.

[0050] In an alternative embodiment, if the user trains 20 times at the current gear, and most of the rolling distances (the leftmost distance and the rightmost distance) do not reach the preset distance (e.g., 3 cm), or if the user trains less than 10 times and the rolling distances are all low (below 3 cm), it indicates that the training intensity at the current gear is relatively large for the user, that is, the current gear exceeds the user's ability to continuously perform wrist training (the initial gear is set too high). At this time, the gear should be lowered by one level to avoid the adverse effects caused by the user continuously training at a gear beyond their ability. By adjusting the user's training gear or magnetic force according to the actual situation of the user, the training safety and training effect of the user can be ensured. In an alternative embodiment, it can also be judged according to the total rolling distance.

[0051] It can be understood that when the highest gear is reached and the above preset conditions are met, the highest gear is maintained. In addition, if the training is manually paused during the training and then continued, a prompt will be given to ask whether to continue the training at the current gear.

[0052] By selecting the training gear and training method according to the user's situation at the beginning of the training, the problem of training with the same intensity (adhesion force) regardless of the user's wrist condition is avoided, thus improving the effect of the user's wrist training; by collecting the training data during the user's training process to adjust the user's training gear or magnetic force, the user can perform effective wrist training according to the magnetic force or gear that more meets their needs, thereby improving the training effect and ensuring the training safety. Moreover, this adjustment is based on the actual wrist condition of the user, which is more objective than judging according to experience and is a real-time adjustment during the training process. Therefore, the training effect and safety are further improved.

[0053] In one embodiment, it further includes: in response to the completion of the user's training, outputting the training result, and the training result can be displayed through a display screen to intuitively show the user's training achievements. The training result can include the training method, training gear, training distance, and training times. For example, the user's training method is: lifting training, the training gear is: 2nd gear, the maximum lifting height is: 15 cm, and the training times are: 46 times (stopped when the training time is reached). In addition, data such as the average lifting height can also be displayed, and those skilled in the art can select according to actual needs.

[0054] In one embodiment, the training result further includes training suggestions. Specifically, the training suggestions include training methods, the training gear or magnetic force for the next training. It can be understood that the training method in the training suggestions is the same as the currently adopted training method. For example, if the currently adopted training method is lifting training, then the training method in the corresponding training suggestions is also lifting training. For the training gear or magnetic force for the next training, it can be determined according to the current training data or the current training data and historical training data. Specifically, the training gear or magnetic force can be determined according to the current training data and the previous training data.

[0055] In one embodiment, if the adopted training is lifting training, the calculation expression for the magnetic force for the next training is:

[0056]

[0057] In the formula, F represents the magnetic force for the next training, F 0 represents the current magnetic force, k is a value between 0 and 1, r 1 is the lifting distance growth rate, r 2 is the lifting times growth rate.

[0058] Among them, calculate the difference between the average value of the lifting distance in the current training and the average value of the lifting distance in the previous training, and then divide it by the average value of the lifting distance in the previous training, that is, the lifting distance growth rate can be obtained; further, calculate the difference between the number of lifting times in the current training and the number of lifting times in the previous training, and then divide it by the number of lifting times in the previous training, that is, the lifting times growth rate can be obtained; further, k is a correction coefficient, which can be adjusted according to the user's physical recovery situation and training goals. In one embodiment, k can take 0.6, or it can be selected according to the user's self-assessment of their own situation.

[0059] In one embodiment, if the adopted training is rolling training, the calculation expression for the magnetic force for the next training is:

[0060]

[0061] In the formula, F represents the magnetic force for the next training, F 0 represents the current magnetic force, k is a value between 0 and 1, r 1 is the total rolling distance growth rate, r 2 is the rolling times growth rate.

[0062] Similarly, calculate the difference between the average value of the total rolling distance in the current training and the average value of the total rolling distance in the previous training, and then compare it with the average value of the total rolling distance in the previous training, so as to obtain the growth rate of the total rolling distance; further, calculate the difference between the number of rolling times in the current training and the number of rolling times in the previous training, and then compare it with the number of rolling times in the previous training, so as to obtain the growth rate of the number of rolling times; further, k is a correction coefficient, which can be adjusted according to the user's physical recovery situation and training goals. In one embodiment, k can be taken as 0.6, or it can be selected according to the user's self-assessment of their own situation.

[0063] The calculated magnetic force can be directly mapped to the magnetic force corresponding to the gear. If the corresponding magnetic force is not found in the gear, it can be determined according to the relationship between the difference between the magnetic force of the next training and the magnetic force corresponding to the current gear and the preset threshold. Specifically, if the difference between the magnetic force of the next training and the magnetic force corresponding to the current gear is greater than or equal to the preset threshold, increase one gear; if the difference between the magnetic force of the next training and the magnetic force corresponding to the current gear is less than the preset threshold, keep the current gear.

[0064] Through the training suggestions given based on the current training data and historical training data, users can start effective training at the beginning of the next training, rather than continuously training according to the current training gear or magnetic force, avoiding the time for adjusting the training gear and improving the training efficiency.

[0065] Although this specification has shown and described multiple embodiments of the present invention, it is obvious to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art will think of many changes, alterations, and alternative ways without departing from the spirit and concept of the present invention. It should be understood that various alternative solutions to the embodiments of the present invention described herein can be adopted in the practice of the present invention.
