Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a foot trainer for assisting patients in performing ankle pump exercises. Background Art

[0002] In the field of modern medical rehabilitation, ankle pump exercises play a crucial role in preventing and improving various diseases and postoperative recovery. Especially for groups such as long-term bedridden patients, postoperative rehabilitation patients, and the elderly, regular and standard ankle pump exercises can effectively promote blood circulation in the lower extremities, prevent deep vein thrombosis, and assist in limb function recovery.

[0003] However, many foot trainers on the market for assisting patients in performing ankle pump exercises have exposed numerous problems in actual applications. On the one hand, from the perspective of patient compliance, a large number of patients cannot reach the ideal training quantity. The lack of an effective guidance mechanism makes it easy for patients to give up halfway and difficult to adhere to the established training frequency. Especially for the elderly patient group, with the decline of physical functions and hearing loss as they age, it is difficult for them to hear the instructions or prompts from conventional training devices clearly. When there is no one to supervise at all times, it is very easy to miss the training time or simply ignore the training tasks.

[0004] Furthermore, insufficient muscle strength is also a key problem affecting the compliance of elderly patients. Due to weak muscle strength, they often have difficulty in performing autonomous ankle pump exercises. Even with the help of existing foot trainers, they may be afraid of and resistant to training due to the difficulty of initial exertion and easy fatigue during the exercise process, and thus are unwilling to cooperate.

[0005] On the other hand, in terms of training standardization, many existing foot trainers fail to solve the problem of non-standard patient movements well. The physical conditions and motor abilities of different patients vary. A training device with a single fixed mode is difficult to adapt to individual differences and cannot accurately assist patients in completing ankle pump movement amplitudes, speeds, and intensities that meet medical requirements. For example, some training devices cannot give personalized feedback and adjustment based on the real-time movement performance of patients, resulting in situations where patients may still have incorrect movements or improper exertion even when using the training device, greatly reducing the training effect and even potentially causing additional discomfort or injury due to incorrect movements.

[0006] In view of the above various situations, there is an urgent need for a foot trainer for assisting patients in performing ankle pump exercises. Summary of the Invention

Detailed implementation manners

[0028] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, with reference to the accompanying drawings and preferred embodiments, describe in detail the specific implementation manners, structures, features and their effects of the present invention.

[0029] As Figures 1-4 shown, a foot trainer for assisting a patient in performing ankle pump exercises includes a substrate 11, a training plate 2 and an angle adjustment mechanism 3; the substrate 11 is used for placing the calf, the training plate 2 is vertically installed on the substrate 11 and is used for placing the foot, and the training plate 2 is rotatably arranged with the substrate 11 to assist the patient in performing ankle pump exercises;

[0030] The angle adjustment mechanism 3 is arranged on one side of the training board 2 and is used to connect the training board 2 and the base plate 11. The angle adjustment mechanism 3 is provided with multiple rotation angle levels, and the multiple rotation angle levels are used to adjust the rotation angle of the training board 2. When a patient performs ankle pump exercises, the calf can be placed on the base plate 11 and the foot can be placed on the training board 2. By adjusting the angle adjustment mechanism 3, the training board 2 can be adjusted to a suitable rotation angle. Then, the patient can actively or passively rotate the training board 2 around the base plate 11 to complete the ankle pump exercise. By setting multiple rotation levels, the foot trainer can meet the specific needs of different patients. Due to differences in the condition, physical condition or rehabilitation stage of different patients, different ankle pump exercise angles may be required. The multiple rotation levels enable the trainer to flexibly adapt to these differences and provide personalized rehabilitation programs for patients. The multiple rotation levels mean that the rotation angle of the training board 2 can be more precisely controlled. This helps to ensure that the patient's movements are in place during the execution of the ankle pump exercise, avoid incorrect exertion, and thus improve the training effect. Precise control also helps to reduce potential injuries caused by improper movements.

[0031] In one embodiment, the angle adjustment mechanism 3 includes a mounting seat 31, a rotating seat 32, an adjustment seat 33 and a clamping block 34. The mounting seat 31 is fixedly arranged on the base plate 11. From the outer ring to the inner ring of the mounting seat 31, the mounting seat 31, the rotating seat 32 and the adjustment seat 33 are coaxially connected in sequence. The rotating seat 32 is also provided with a connecting portion 321, and the connecting portion 321 is fixedly connected to the training board 2. The adjustment seat 33 is provided with a number of rotating grooves 331 with gradually increasing rotation ranges on the adjacent surface to the rotating seat 32. The clamping block 34 is arranged on the rotating seat 32 and selectively slides in the rotating grooves 331. Along the axial direction of the mounting seat 31, the adjustment seat 33 moves relative to the rotating seat 32 to change the matching relationship of the clamping block 34 between a number of rotating grooves 331 at different rotation angles. When it is necessary to adjust the rotation angle of the training board 2, it can be achieved by changing the position of the adjustment seat 33 relative to the rotating seat 32. After the clamping block 34 is pulled out from the current clamping groove, it is axially moved along the mounting seat 31 to an appropriate rotation angle and the clamping block 34 is inserted again, so that the clamping block 34 slides from the current rotating groove 331 to another rotating groove 331. Since the rotation ranges of different rotating grooves 331 are different, the position of the clamping block 34 in different rotating grooves 331 determines the rotation angle of the training board 2. It can assist the patient to perform standardized ankle pump exercises with a personal rotation angle.

[0032] In one embodiment, a fixing mechanism 4 is further included. The fixing mechanism 4 is used to fix the adjusting seat 33 on the mounting seat 31. The fixing mechanism 4 includes an embedding block 41, a telescopic block 42 and a locking block 43. The embedding block 41 is fixedly arranged on the adjusting seat 33 and is clamped with the corresponding structure on the mounting seat 31 to limit the axial movement of the adjusting seat 33 on the mounting seat 31, that is, to prevent the adjusting seat 33 from rotating together with the training board 2 when the training board 2 rotates, thus resulting in inaccurate rotation angle of the rotation groove 331. The telescopic block 42 is installed on the mounting seat 31 and has a certain telescopic ability. The telescopic block 42 is to adapt to the needs of the adjusting seat 33 during axial movement, ensure that the locking block 43 can move along with the movement of the adjusting seat 33, and at the same time maintain the locking ability for the adjusting seat 33. That is, when the adjusting seat 33 is adjusted in angle by moving axially on the mounting seat 31, the adjusting seat 33 will move relative to the locking block 43. Therefore, it is necessary to ensure that the locking block 43 can be locked with the mounting seat 31 through the telescopic block 42. The locking block 43 is installed on the telescopic block 42 and is used to temporarily fix the adjusting seat 33 on the mounting seat 31. After the adjusting block adjusts the rotation angle, the adjusting seat 33 is fixed to the mounting seat 31, so that when the rotating seat 32 rotates, it can rotate accurately according to the rotation angle of the rotation groove 331.

[0033] In one embodiment, the clamping block 34 moves up and down relative to the mounting seat 31. When the adjusting seat 33 moves axially, the clamping block 34 extends out of the rotation groove 331, so that the clamping block 34 can smoothly adjust the rotation angle. After the angle of the adjusting seat 33 is adjusted, the clamping block 34 moves downward from the mounting seat 31 and is clamped in the clamping groove. When the training board 2 performs ankle pump exercises, the clamping block 34 can only rotate within the rotation range of the clamping groove, that is, the rotation angle of the training board 2 is limited by the angle range of the rotation groove 331, so that the ankle pump exercise meets the requirements of norms and standards.

[0034] In one embodiment, a driving assembly 5 and a clutch assembly 6 are further included. One end of the training board 2 far from the angle adjusting mechanism 3 is rotatably connected to the base plate 11 through a rotating shaft 12. The driving assembly 5 is used to drive the rotating shaft 12 to rotate passively. The clutch assembly 6 is installed between the driving assembly 5 and the rotating shaft 12 and is used to separate the passive drive of the driving assembly 5. The clutch assembly 6 includes a first bearing 61, a second bearing 62 and a fixing member 63. The first bearing 61 and the second bearing 62 are coaxially connected to the rotating shaft 12 and the output shaft of the driving assembly 5 respectively. The second bearing 62 is sleeved on the outer ring of the first bearing 61 to realize the relative rotation between the driving assembly 5 and the rotating shaft 12. The fixing member 63 is used to fix the first bearing 61 and the second bearing 62 to realize the synchronous movement between the driving assembly 5 and the rotating shaft 12.

[0035] In the initial state, the clutch assembly 6 is in a disengaged state, that is, the first bearing 61 and the second bearing 62 can rotate relative to each other. At this time, even if the driving assembly 5 is started, the training board 2 will not be directly driven to rotate because there is no fixed connection between the rotating shaft 12 and the output shaft of the driving assembly 5. In this mode, patients with better foot strength can choose the active training mode. In the active training mode, the rotating shaft 12 rotates relative to the base plate 11 by the strength of the foot. At this time, the clutch assembly 6 remains in the disengaged state, that is, the first rotating shaft 12 and the second rotating shaft 12 can move relative to each other, and the driving assembly 5 does not participate in the rotation. At this time, the rotation of the training board 2 is not affected by the driving assembly 5;

[0036] For passive movement, when it is necessary for the driving assembly 5 to provide power to drive the training board 2 to rotate, first lock the first bearing 61 and the second bearing 62 through the fixing member 63 to achieve the synchronous movement of the output shaft of the driving assembly 5 and the rotating shaft 12, and then start the driving assembly 5. The output shaft transmits the power to the rotating shaft 12, thereby driving the training board 2 to perform ankle pump exercise. This mode is suitable for the elderly and those who need assistance due to insufficient foot strength;

[0037] In addition, the training board 2 should also be provided with straps for fixing the feet to better adapt to the ankle pump exercise with the feet fitting the training board 2;

[0038] When it is necessary to switch between the passive rotation mode and the active driving mode, only the state of the clutch assembly 6 needs to be adjusted. By releasing or locking the fixing member 63, it is possible to easily switch between the two modes, and the fastener is realized by the prior art, such as using pin, buckle and other technologies;

[0039] The foot trainer of this embodiment not only provides two rotation modes of active and passive, but also retains the ability to manually adjust the angle, greatly improving the flexibility and adaptability of training. Patients can choose the appropriate training mode according to their own rehabilitation needs and physical conditions, so as to more effectively promote the execution of ankle pump exercise and the rehabilitation process.

[0040] In one embodiment, a detection board 13 is further vertically disposed on the substrate 11. The detection board 13 is located at the bottom of the training board 2. A pressure sensor 7 is disposed on the detection board 13. The pressure sensor 7 is used to detect the pressure generated when the training board 2 rotates. When the patient performs ankle pump exercises, the training board 2 will swing around its rotation axis 12 with the substrate 11. During this process, the bottom of the training board 2 will contact the detection board 13 and apply different magnitudes of pressure at different angles. The pressure sensor 7 can sense these pressure changes in real time and convert them into electrical signals. These electrical signals are then transmitted to the control system. The control system can obtain key indicators such as the pressure distribution, peak pressure, and average pressure of the training board 2 at different angles through processing and analysis of the received electrical signals. Based on the collected data, the rehabilitation therapist or the patient can understand the training effect in real time and make corresponding adjustments as needed. For example, if it is found that the pressure at a certain angle is insufficient, the training intensity or the angle adjustment mechanism 3 can be adjusted to ensure the best effect of the ankle pump exercise.

[0041] In one embodiment, a control system is further included. The pressure sensor 7 is connected to the control system. The pressure sensor 7 is used to record the pressure generated when the training board 2 rotates and upload it to the control system. The control system further includes a timing module and a buzzer module. The timing module times the time when the pressure is generated and uploads it to the control system. The control system is provided with a time threshold. After the timed time exceeds the threshold, the control system controls the buzzer module to emit a beep. When the patient uses the foot trainer to perform ankle pump exercises, the training board 2 will rotate around a specific rotation axis 12. When the training board 2 rotates, it will abut against the detection board 13. Thus, the pressure sensor 7 can monitor the pressure generated when the training board 2 rotates in real time and upload its data to the control system. The control system receives the pressure sensor 7 and conducts analysis. Further, the number of pressure sensors 7 is two. One is located at the upper end of the detection board 13, and the other is located at the lower end of the detection board 13. When the foot performs a straightening movement, the training board 2 rotates backward and abuts against the upper end of the detection board 13. The pressure sensor 7 at the upper part detects the pressure generated during straightening and uploads it to the control system. The timing module continuously times the sensor that generates pressure in the abutting state. When the timed time exceeds the set threshold, the control system controls the buzzer module to emit a beeping sound, indicating that the current foot straightening movement angle, strength, and duration have been completed, indicating to the patient that they can perform the tightening action of the foot. The tightening action causes the training board 2 to move forward. At this time, the lower part of the training board 2 touches the sensor at the lower part of the detection board 13. Similarly, based on the detection principle of the straightening movement, until the buzzer module emits an alarm sound, at this time, a complete and standard ankle pump exercise is completed.

[0042] In one embodiment, the control system is provided with an input module for inputting the rotation angle of the training board 2. The driving component 5 is electrically connected to the control system, and the control system controls the driving component 5 to rotate reciprocally according to the angle of the input module to achieve the passive movement of the training board 2. The user sets training parameters through the input module, such as the rotation angle of the training board 2, the training time, etc. The control system sends a control instruction to the driving component 5 through the electrical connection. The driving component 5 is a motor, a hydraulic cylinder or other types of brakes, and it starts to work according to the received instruction to drive the training board 2 to rotate reciprocally at the set angle; under the action of the driving component 5, the training board 2 rotates passively at the preset angle, thereby assisting the patient to perform ankle pump exercises. This passive movement mode is particularly suitable for patients with insufficient muscle strength or those who need additional assistance. By setting the specific rotation angle through the input module, the patient can perform personalized training according to their individual rehabilitation needs and muscle strength level, improving the pertinence and effectiveness of the training; for patients with insufficient muscle strength or those who need additional assistance, the passive movement function provided by the driving component 5 can greatly reduce their burden, help them complete ankle pump exercises, and promote the rehabilitation process.

[0043] In one embodiment, the control system is further provided with a counting module for recording the number of ankle pump exercises. The user (patient or medical staff) sets training parameters through the input module, such as the rotation angle of the training board 2, the training time, etc. At the same time, the control system initializes the counting module, clears the number of ankle pump exercises to zero, and prepares to start a new training session. The patient starts to use the foot trainer to perform ankle pump exercises. If the trainer is designed in the passive mode, the driving component 5 will automatically drive the training board 2 to rotate according to the preset parameters; if it is in the autonomous mode, the patient needs to rotate the training board 2 by themselves; the control system receives the data from the pressure sensor 7 and the angle detector and makes a comprehensive judgment. If the training board 2 reaches the preset angle requirement within the set time and the pressure data also meets the specified range, it is judged as a valid ankle pump exercise. After this judgment is made as a valid exercise, the counting module automatically increases the record of the number of ankle pump exercises, providing a reliable basis for subsequent data analysis and training plan adjustment.

[0044] In one embodiment, the connecting portion 321 is located in the middle of the training board 2. When the rotation point is located in the middle of the training board 2, the patient can achieve a larger range of ankle joint movement with a smaller lever arm. That is, the longer the lever arm, the smaller the required force; conversely, the shorter the lever arm, the greater the required force. Therefore, the middle rotation point makes the training board 2 more efficient when rotating; the design of the middle rotation point makes the training board 2 more balanced when rotating, reducing the additional resistance generated by the gravity effect, helping the patient to complete the ankle pump exercise more easily, reducing the discomfort during the exercise, and the middle rotation point design can more accurately simulate the natural movement pattern of the ankle joint. This enables the patient to move the ankle joint more naturally during the ankle pump exercise, thereby exercising the relevant muscle groups more effectively. This design helps to improve the training effect and promote the rehabilitation of the ankle joint; while the traditional bottom rotation point design may cause unnecessary torque and shear force during the training, increasing the risk of sports injury; and the middle rotation point design can disperse these forces more effectively, reducing the injury risk; since the middle rotation point design can more accurately simulate the natural movement pattern of the ankle joint, the patient can exercise the relevant muscle groups more effectively during the ankle pump exercise, improving the training effect.

[0045] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments with the same changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
