Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an ankle pump exercise training method and device. Background Art

[0002] Ankle pump exercises are a fundamental training method for postoperative rehabilitation and chronic diseases (such as lower extremity deep vein thrombosis, rheumatoid arthritis, and long-term bedridden patients). Through periodic ankle flexion and extension (dorsiflexion, plantar flexion) and circumduction movements, they can promote lower limb blood circulation and prevent muscle atrophy and joint stiffness, much like a pump. However, related ankle pump exercise training has the following drawbacks:

[0003] (1) Difficulty in quantifying exercise: In clinical practice, the number of movements and the range of motion often rely on the patient's subjective report or manual counting, which can easily lead to data deviation and make it impossible to accurately assess the rehabilitation effect.

[0004] (2) Insufficient personalized adaptation: There are individual differences in muscle strength and joint range of motion among patients, but traditional equipment lacks resistance adjustment and range of motion grading functions, which can easily lead to insufficient training intensity or excessive fatigue.

[0005] (3) Lack of standardized movement: Patients often fail to perform ankle pump movements properly due to pain or insufficient muscle strength (such as insufficient flexion and extension angles). Related equipment cannot monitor the movement trajectory in real time, making it difficult to ensure the effectiveness of functional training.

[0006] (4) Delayed warning of fatigue risk: Excessive exercise may induce local inflammation or edema, and sports injuries cannot be warned in time.

[0007] (5) The contradiction between portability and compliance: Traditional training equipment is bulky and difficult to store, which limits patients' use at home or in the ward and affects long-term rehabilitation compliance. Summary of the Invention

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0066] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "located in," and "located in" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections, mechanical connections or chemical connections, direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0067] Some embodiments of the present invention disclose an ankle pump exercise training method for postoperative rehabilitation and lower limb rehabilitation training for patients with chronic diseases. The ankle pump exercise includes ankle flexion and extension exercises and ankle circumduction exercises. The ankle flexion and extension exercises include ankle dorsiflexion exercises and ankle plantarflexion exercises. One or more movements need to be repeated periodically during training.

[0068] For example, when a patient extends their foot, from the patient's perspective, ankle dorsiflexion involves slowly pointing the toes upwards from the heel, ensuring the toes point towards the patient, holding this position for 5 seconds. Ankle plantar flexion involves pressing the toes downwards from the heel, maximizing the downward pointing, and holding for 5 seconds. Ankle circumduction involves making a 360-degree circle around the heel, maximizing the range of motion, performing each circle clockwise and counterclockwise for 10 seconds. It should be noted that the 5-second and 10-second intervals are merely examples and not intended to limit this application; other variations are also possible.

[0069] like Figure 1 As shown, this ankle pump exercise training method is applied to the processor and specifically includes the following steps:

[0070] Obtain standard parameters from patients when performing pre-defined standard ankle flexion-extension and ankle circumduction movements;

[0071] Obtain training parameters from patients during ankle flexion-extension and ankle circumduction exercises;

[0072] Based on the standard and training parameters of ankle flexion and extension movements, determine whether the training movements of ankle flexion and extension movements are qualified, and count the qualified ankle flexion and extension training movements.

[0073] Based on the standard and training parameters of ankle circling movements, we determine whether the training movements of ankle circling movements are qualified, and count the qualified ankle circling movement training movements.

[0074] The ankle pump exercise training method in this embodiment can preset different standards for ankle flexion-extension and ankle circumduction exercises according to the patient's physical differences, improving personalized adaptation and avoiding undertraining or overtraining. Furthermore, this ankle pump exercise training method can accurately quantify the range of motion and number of repetitions while ensuring proper movement, improving functional training effects and facilitating rehabilitation outcome assessment.

[0075] The following is Figure 3 and Figure 4 The illustrated scheme, comprising a locator, a telescopic measuring element, and an array of infrared sensors, calculates the horizontal position, circumferential radius, and circumferential period by detecting changes in the position of the toes in three-dimensional space. Calibration requires precise measurement and setting of the maximum horizontal position of standard dorsiflexion, the maximum horizontal position of standard plantar flexion, the maximum circumferential radius, and the standard circumferential period; the counting depends on whether the toes reach the preset spatial position.

[0076] The following ankle flexion-extension and ankle circumduction movements are all performed with the locator aligned with the patient's heel. A coordinate system is established with the locator (heel) as the center point. The Z-axis is perpendicular to the horizontal bed surface, the Y-axis is along the horizontal direction of the ankle flexion-extension movement, that is, the Y-axis is along the horizontal front-back direction, and the X-axis is along the horizontal left-right direction.

[0077] When a patient performs ankle dorsiflexion, the movement is in the horizontal direction toward the patient (i.e., backward). When a patient performs ankle plantarflexion, the movement is in the horizontal direction away from the patient (i.e., forward).

[0078] In some embodiments, standard parameters are obtained when a patient performs a preset standard ankle flexion and extension movement, including:

[0079] The maximum horizontal position of standard dorsiflexion and the maximum horizontal position of standard plantarflexion are obtained by measuring the patient's ankle dorsiflexion and plantarflexion movements using a telescopic measuring device. The horizontal position is the length on the Y-axis.

[0080] Obtain training parameters from patients during ankle flexion and extension exercises, including:

[0081] The system obtains the movement trajectory of the toes in real time by an array of infrared sensors during ankle dorsiflexion and plantarflexion exercises. The maximum horizontal position of dorsiflexion and plantarflexion exercises is obtained by analyzing the position coordinates of the movement trajectory.

[0082] The trajectory of the toe is calculated in real-time from the data processed by the Kalman filter algorithm, yielding the position coordinates at different time points. The Kalman filter is a recursive filtering algorithm capable of real-time processing and fusion of sensor data. It continuously optimizes the estimation of the foot's position through two steps: prediction and update. In the prediction step, the position at the next moment is predicted based on the toe's position and movement state at the previous moment. In the update step, newly measured sensor data is compared with the predicted value, and the position estimate is adjusted according to the error. In this way, the Kalman filter can effectively eliminate measurement noise and interference, improving the accuracy and stability of positioning.

[0083] Based on the standard and training parameters of ankle flexion and extension movements, the adequacy of ankle flexion and extension training movements is determined. The number of adequacy ankle flexion and extension training movements is counted, including:

[0084] When the maximum horizontal position of dorsiflexion training is greater than or equal to the maximum horizontal position of standard dorsiflexion (first preset percentage), and the maximum horizontal position of plantarflexion training is greater than or equal to the maximum horizontal position of standard plantarflexion (second preset percentage), the ankle flexion and extension exercise is considered a qualified movement, and the count is incremented by 1. The first preset percentage and the second preset percentage may be the same or different. For example, if the first preset percentage and the second preset percentage are 80%, this 80% is merely an example and not intended to limit this application; other percentages are also possible.

[0085] In some embodiments, the amplitude attenuation of ankle flexion and extension movements can be dynamically monitored. The ankle joint exercise training method further includes: when the maximum horizontal position of dorsiflexion training is less than the maximum horizontal position of standard dorsiflexion by a first preset percentage, and / or the maximum horizontal position of plantarflexion training is less than the maximum horizontal position of standard plantarflexion by a second preset percentage, fatigue counting is performed, and when the fatigue count reaches a threshold, a fatigue warning is triggered.

[0086] In some embodiments, the ankle joint exercise training method further includes synchronizing the standard parameters and training parameters of ankle flexion and extension movements, the judgment results of whether the training movements of ankle flexion and extension movements are qualified, and their counts to a mobile terminal to facilitate the tracking and management of rehabilitation progress.

[0087] In some embodiments, standard parameters are obtained when a patient performs a preset standard ankle circumduction motion, including:

[0088] The system obtains the movement trajectory and movement time of the toes in real time by an array of infrared sensors when the patient performs a preset standard ankle joint circumduction exercise. The maximum circumduction radius is obtained based on the position coordinates of the movement trajectory, and the standard circumduction cycle is obtained based on the movement time.

[0089] Obtain training parameters from patients during ankle circumduction exercises, including:

[0090] The system obtains the movement trajectory and movement time of the toes in real time by an array of infrared sensors during the patient's ankle joint circumduction training. The average circumduction radius is obtained based on the position coordinates of the movement trajectory, and the training circumduction cycle is obtained based on the movement time.

[0091] Based on the standard and training parameters of ankle circling movements, the qualification of ankle circling movement training exercises is determined, and the number of qualified ankle circling movement training exercises is counted, including:

[0092] When the movement trajectory of the toes is a closed loop, the average circumferential radius is greater than or equal to the maximum circumferential radius of the third preset percentage, and the training circumferential cycle is within the standard circumferential cycle range of the preset multiple, the training action of ankle joint circumferential movement is a qualified action, and the count is incremented by 1.

[0093] The third preset percentage may be the same as or different from the first and second preset percentages. For example, the third preset percentage may be 80%, and the training orbital period may be ∈ [0.9T, 1.1T], where T is the standard orbital period. It should be noted that 80%, 0.9T and 1.1T are just examples and are not intended to limit this application. They may also be other values.

[0094] In some embodiments, when the patient performs ankle circumduction movements, an array of infrared sensors tracks the position coordinates (x, y, y) of the toes at different time points in real time. i ,y i This constitutes the movement trajectory of the ankle joint in a circular motion.

[0095] Radius calculation: Calculate the radius of each trajectory point with the heel as the center point. These radius values ​​reflect the distance between the toes and the center point at different positions.

[0096] Average orbital radius calculation: To determine whether the orbital radius meets the condition, the average orbital radius of all trajectory points can be calculated. Where n is the number of trajectory points, and the average orbital radius r ― It can be used as a feature of the overall radius of the orbital motion.

[0097] Judgment condition: The calculated average radius of circumference r ― Compare with the maximum orbital radius R to determine if r is satisfied. ― If the condition ≥0.8R is met, then the effective radius of the orbital motion is considered to meet the requirements.

[0098] In some embodiments, the amplitude decay of ankle joint circumduction can be dynamically monitored. Therefore, the ankle joint exercise training method further includes: when the average circumduction radius is less than the maximum circumduction radius of the third preset percentage, and / or the training circumduction cycle is not within the range of the standard circumduction cycle of the preset multiple, fatigue counting is performed, and when the fatigue count reaches the threshold, a fatigue warning is triggered.

[0099] In some embodiments, the ankle joint exercise training method further includes: synchronizing the standard parameters and training parameters of ankle joint circumduction, the judgment results of whether the ankle joint circumduction training movements are qualified and their counts to the matching mobile terminal, so as to facilitate the tracking and management of rehabilitation progress.

[0100] The following is a pressure sensor solution that relies on detecting the pressure distribution, intensity, and changes generated when the sole of the foot contacts the pressure sensor to infer movement. Calibration requires recording standard pressure characteristics for dorsiflexion, plantarflexion, and circumduction. Counting depends on whether the preset standard pressure characteristics for dorsiflexion, plantarflexion, and circumduction are reproduced. This pressure sensor solution focuses more on the continuous contact mechanics between the sole of the foot and the pressure sensor, rather than discrete spatial coordinates. It is minimally affected by ambient light, smoke, or obstructions from bed sheets. Compared to infrared sensor solutions, this pressure sensor solution includes temporal information about the movement (how the pressure changes), making it easier to determine whether the movement is complete and smooth. Infrared sensor solutions mainly focus on whether a preset spatial position has been reached, thus providing a more direct assessment of movement completeness. In addition, the requirement for absolute accuracy of foot position is reduced. As long as the sole of the foot is roughly within the pressure sensor area, the solution focuses on the relative pressure distribution and change patterns. The dependence on whether the heel is precisely aligned with the locator is lower than that of the infrared sensor solution, reducing the requirement for absolute positioning accuracy.

[0101] Therefore, in some embodiments, standard parameters are obtained when the patient performs preset standard ankle flexion-extension and ankle circumduction movements, including:

[0102] The system acquires real-time pressure characteristics of the sole of the foot during the patient's performance of preset standard ankle dorsiflexion, plantar flexion, and circumduction movements using pressure sensors. The pressure characteristics include the movement trajectory of the center point of pressure on the sole of the foot and the pressure peak and variation curves in different areas of the sole.

[0103] Obtain training parameters from patients during ankle flexion-extension and ankle circumduction exercises, including:

[0104] The system acquires real-time pressure characteristics of the sole of the foot during ankle dorsiflexion, plantar flexion, and circumduction exercises, captured by pressure sensors.

[0105] When patients perform ankle dorsiflexion exercises, they should point their toes as far as possible in the direction of their body. The pressure sensor will detect that the center of pressure moves backward (towards the heel), resulting in a significant increase in pressure in the heel area and a relative decrease in pressure in the forefoot area.

[0106] When the patient performs plantar flexion of the ankle joint and points the toes downward as much as possible, the pressure sensor detects that the center of pressure moves forward (in the direction of the forefoot), and the pressure in the forefoot area (especially below the metatarsal heads) increases significantly, while the pressure in the heel area may decrease relatively.

[0107] Based on the standard and training parameters of ankle flexion and extension movements, the adequacy of ankle flexion and extension training movements is determined. The number of adequacy ankle flexion and extension training movements is counted, including:

[0108] When the matching degree between the dorsiflexion training pressure characteristic and the standard dorsiflexion pressure characteristic reaches a first preset value, and the matching degree between the plantarflexion training pressure characteristic and the standard plantarflexion pressure characteristic reaches a second preset value, the ankle flexion and extension exercise is considered a qualified movement, and the count is incremented by 1. The first and second preset values ​​may be the same or different; for example, if the first and second preset values ​​are both 90%, this 90% is merely an example and not intended to limit this application; other values ​​are also possible.

[0109] Based on the standard and training parameters of ankle circling movements, the qualification of ankle circling movement training exercises is determined, and the number of qualified ankle circling movement training exercises is counted, including:

[0110] When the matching degree between the circumferential training pressure feature and the circumferential standard pressure feature reaches a third preset value, the ankle joint circumferential movement training action is considered a qualified action, and the count is incremented by 1. The third preset value may be the same as or different from the first and second preset values. For example, the third preset value may be 90%. This 90% is merely an example and not intended to limit this application; other values ​​are also possible.

[0111] In some embodiments, pressure characteristics can reveal whether the patient is compensating with incorrect muscle groups (such as overuse of the toes), which is difficult to achieve directly using infrared methods. Therefore, this ankle pump exercise training method also includes analyzing the uniformity of force exertion based on the pressure characteristics of dorsiflexion training, plantar flexion training, and circumduction training. For example, whether the force exertion during dorsiflexion is mainly generated by the ankle (the pressure change mainly shifts between the heel and the forefoot), rather than relying excessively on toe gripping (leading to abnormally high local pressure in the forefoot).

[0112] This embodiment uses pressure characteristics to determine whether the training movements of ankle joint circumduction are qualified. It can completely change the discrete point accumulation logic and realize the direct evaluation of the quality of continuous, smooth and complete circumduction training movements. It can comprehensively judge the amplitude, standardization, smoothness and force uniformity, which is more in line with the essential requirements of circumduction.

[0113] In some embodiments, the ankle pump exercise training method further includes:

[0114] Record the number of repetitions and the sequence of at least one of the following ankle movements during training: ankle dorsiflexion, ankle plantarflexion, and ankle circumduction. Compare this data with a pre-set set of quasi-training movements to obtain an evaluation of training completeness. The pre-set quasi-training movements include the number of repetitions and the sequence of at least one of the following three movements: ankle dorsiflexion, ankle plantarflexion, and ankle circumduction. Understandably, "at least one" can refer to one type, two types, or any number of movements.

[0115] like Figure 2 As shown, some embodiments of the present invention also disclose an ankle pump exercise training device, comprising:

[0116] one or more processors;

[0117] A storage device for storing one or more programs, which, when executed by one or more processors, cause the one or more processors to implement the ankle pump exercise training method as described in any of the above embodiments.

[0118] In some embodiments, such as Figure 3 and Figure 4 As shown, the ankle pump exercise training device also includes a first telescopic measuring element 10, a second telescopic measuring element 11, a locator 12, a first infrared sensor 13, and a second infrared sensor 14, as detailed below:

[0119] The first telescopic measuring element 10 is telescopic in the horizontal direction (i.e., Y-axis) of the ankle dorsiflexion movement. The first telescopic measuring element 10 is used to measure the maximum horizontal position (i.e., the length on the Y-axis) reached by the patient when performing a preset standard ankle dorsiflexion movement.

[0120] The extension direction of the second telescopic measuring element 11 is in the horizontal direction of the ankle plantar flexion movement (i.e., the Y-axis). The second telescopic measuring element 11 is used to measure the maximum horizontal position (i.e., the length on the Y-axis) reached by the patient when performing a preset standard ankle plantar flexion movement.

[0121] The first telescopic measuring element 10 and the second telescopic measuring element 11 are both on the Y-axis. The locator 12 is located at the connection between the first telescopic measuring element 10 and the second telescopic measuring element 11. The locator 12 is used to locate the patient's heel, and the locator 12 (or the heel) is the center of the coordinate system.

[0122] The first infrared sensor 13 is located at the end of the first telescopic measuring member 10, and the second infrared sensor 14 is located at the end of the second telescopic measuring member 11. The detection range formed by the first infrared sensor 13 and the second infrared sensor 14 is a surface that covers the range of movement of the toe. The first infrared sensor 13 and the second infrared sensor 14 are respectively connected to the processor for real-time detection of the infrared signal reflected by the toe and conversion into an electrical signal, which is then analyzed by the processor to obtain the movement trajectory of the toe.

[0123] For example, the first telescopic measuring element 10 and the second telescopic measuring element 11 are telescopic scales, and the positioner 12 is an alignment light source that can emit stable visible light. The telescopic scale and alignment light source here are just examples and are not intended to limit this application. They can also be other types.

[0124] In some embodiments, the ankle pump exercise training device further includes a third retractable measuring element 15, a fourth telescopic measuring element 16, a third infrared sensor 17, and a fourth infrared sensor 18, as detailed below:

[0125] The first telescopic measuring element 10, the second telescopic measuring element 11, the third telescopic measuring element 15, and the fourth telescopic measuring element 16 are on the same horizontal plane. The first telescopic measuring element 10 and the second telescopic measuring element 11 are on the same Y-axis, and the third telescopic measuring element 15 and the fourth telescopic measuring element 16 are on the same X-axis. The third infrared sensor 17 is located at the end of the third telescopic measuring element 15, and the fourth infrared sensor 18 is located at the end of the fourth telescopic measuring element 16.

[0126] Specifically, the first infrared sensor 13 and the second infrared sensor 14 (or the first infrared sensor 13, the second infrared sensor 14, the third infrared sensor 17, and the fourth infrared sensor 18) form an array. The first infrared sensor 13 and the second infrared sensor 14 can detect the infrared signals reflected by the toes in real time and convert them into electrical signals. The signal intensity detected by each sensor is related to the position and distance of the toes. By analyzing these signals, the processor can determine the position coordinates of the toes in space, and thus analyze the movement trajectory of the toes based on the position coordinates, thereby further obtaining the maximum horizontal position for dorsiflexion training, the maximum horizontal position for plantarflexion training, and the circumferential radius.

[0127] For example, the first infrared sensor 13, the second infrared sensor 14, the third infrared sensor 17 and the fourth infrared sensor 18 are reflective active infrared sensing devices, with the transmitter and receiver located at the same end, generating electrical signals by detecting changes in the infrared signal reflected from the toes.

[0128] In some embodiments, such as Figure 3 and Figure 4 As shown, the ankle pump exercise training device also includes a fixing mechanism 19 and a support mechanism 20. The fixing mechanism 19 is used to fix it to an external fastener, and the connection between the first telescopic measuring element 10 and the second telescopic measuring element 11 is rotatably connected to the other end of the support mechanism 20.

[0129] Specifically, before training, the fixation mechanism 19 is fixed to an external fastener (such as the foot of the bed). The patient's foot is placed 22-28 cm below the first telescopic measuring element 10 and the second telescopic measuring element 11 (or the first telescopic measuring element 10, the second telescopic measuring element 11, the third telescopic measuring element 15, and the fourth telescopic measuring element 16). The first telescopic measuring element 10 and the second telescopic measuring element 11 rotate to correspond to the direction of ankle dorsiflexion and ankle plantarflexion. The locator 12 is aligned with the patient's heel. The patient performs a preset standard ankle flexion and extension movement and an ankle circumduction movement. This preset standard can be changed according to the patient's physical condition or the doctor's requirements. At the same time, the first telescopic measuring element 10 and the second telescopic measuring element 11 measure the maximum horizontal position of the standard dorsiflexion and the maximum horizontal position of the standard plantarflexion by telescopic movement, and input the data into the processor. Furthermore, the processor uses the signals fed back by the first infrared sensor 13 and the second infrared sensor 14 (or the first infrared sensor 13, the second infrared sensor 14, the third infrared sensor 17 and the fourth infrared sensor 18) to track the movement trajectory and movement time of the toes of the patient in real time when performing a preset standard ankle joint circumduction movement. The processor obtains the maximum circumduction radius based on the position coordinates of the movement trajectory and the standard circumduction cycle based on the movement time.

[0130] After presetting the maximum horizontal position of standard dorsiflexion, the maximum horizontal position of standard plantarflexion, the maximum circumduction radius, and the standard circumduction cycle, training begins. The patient performs ankle dorsiflexion, plantarflexion, and circumduction exercises independently. The processor uses signals from the first infrared sensor 13 and the second infrared sensor 14 (or the first infrared sensor 13, the second infrared sensor 14, the third infrared sensor 17, and the fourth infrared sensor 18) to track the movement trajectory of the toes during ankle dorsiflexion and plantarflexion exercises in real time. The processor analyzes the position coordinates of the movement trajectory to obtain the maximum horizontal position of dorsiflexion and plantarflexion exercises. When the maximum horizontal position of dorsiflexion is greater than or equal to the first preset percentage of the maximum horizontal position of standard dorsiflexion, and the maximum horizontal position of plantarflexion is greater than or equal to the second preset percentage of the maximum horizontal position of standard plantarflexion, the ankle flexion and extension exercise is considered a qualified exercise, and the count is incremented by 1. In addition, the processor uses signals fed back from the first infrared sensor 13 and the second infrared sensor 14 (or the first infrared sensor 13, the second infrared sensor 14, the third infrared sensor 17, and the fourth infrared sensor 18) to track the movement trajectory and movement time of the toes during ankle joint circumduction training in real time. The processor obtains the average circumduction radius based on the position coordinates of the movement trajectory and the training circumduction cycle based on the movement time. When the movement trajectory of the toes is a closed loop, the average circumduction radius is greater than or equal to the maximum circumduction radius of the third preset percentage, and the training circumduction cycle is within the standard circumduction cycle range of a preset multiple, the ankle joint circumduction training action is considered a qualified action, and the count is incremented by 1. This scheme can accurately quantify the range of motion and number of movements while ensuring the standardization of the action, improving the functional training effect, facilitating the evaluation of rehabilitation effect, and the counting error rate of this scheme is ≤±3%.

[0131] In some embodiments, the telescopic measuring element is a sliding telescopic or rotating telescopic element, such as a telescopic ruler made of a rigid material (such as metal), with a scale of 0-28cm, three telescopic sections, supporting three length adjustments, each section being 9cm and the last section being 10cm. This is just an example and is not intended to limit this application; other elements may also be used.

[0132] In some embodiments, the ankle pump exercise training device further includes an adjustment mechanism 21, wherein the connection between the first telescopic measuring element 10 and the second telescopic measuring element 11 (or the first telescopic measuring element 10, the second telescopic measuring element 11, the third telescopic measuring element 15 and the fourth telescopic measuring element 16) is rotatably connected to the other end of the support mechanism 20 through the adjustment mechanism 21, and the adjustment mechanism 21 is used to adjust the orientation of the telescopic measuring element.

[0133] For example, such as Figure 5As shown, the steering mechanism 21 is a universal joint, which comprises a first U-shaped fork 211, a second U-shaped fork 212, a cross shaft 213, a bearing 214, and a first locking member 215. The first U-shaped fork 211 and the second U-shaped fork 212 are connected together by the cross shaft 213. Bearings 214 are respectively installed at the ends of the cross shaft 213. The first locking member 215 is used to lock the cross shaft 213 at both ends of the first U-shaped fork 211 and / or the second U-shaped fork 212. The first U-shaped fork 211 is rotatably connected to the other end of the support mechanism 20, and the second U-shaped fork 212 is fixedly connected to the connection between the first telescopic measuring member 10 and the second telescopic measuring member 11. When the shaft at either end rotates, it will drive the other shaft to rotate. At the same time, due to the presence of the bearing 214, it can swing around the center of the cross shaft 213 in a certain angle direction, realizing stepless adjustment. For example, the first locking element 215 is a bolt, and the first U-shaped shaft fork 211 and / or the second U-shaped shaft fork 212 have threaded holes at both ends. The bolt locks the cross shaft 213 through frictional contact with the cross shaft 213. In actual operation, when it is necessary to adjust the direction, the bolt can be loosened to separate it from the cross shaft 213. After adjusting the direction by rotation, the bolt can be tightened again to make it frictionally contact the cross shaft 213.

[0134] In some embodiments, such as Figure 3 and Figure 4 As shown, the infrared sensor is rotatably connected to the end of the telescopic measuring component, allowing adjustment of the infrared sensor's detection angle. For example, the first infrared sensor 13 and the end of the first telescopic measuring component 10 are rotatably connected via a shaft 22. Figure 3 Taking the indicated orientation as an example, the first infrared sensor 13 can rotate up and down around the axis 22.

[0135] In some embodiments, such as Figure 3 and Figure 4 As shown, the fixing mechanism 19 is a fixing clip that can be clipped to the foot of the bed or other places. The fixing clip and foot of the bed mentioned here are just examples and are not intended to limit this application. Others are also possible.

[0136] In some embodiments, such as Figure 3 and Figure 4As shown, to achieve portability, the support mechanism 20 is a foldable support rod. The structure is lightweight, easy to store and carry, and suitable for use at home and in hospital wards, thereby improving patient compliance. Specifically, the support rod includes at least two rod segments. Understandably, the at least two segments can be two, three, or any number of segments. A folding structure is provided between each pair of rod segments. The folding structure includes a first connector 201, a second connector 202, and a second locking member 203. The first connector 201 is connected to one of the rod segments, and the second connector 202 is connected to the other rod segment. The first connector 201 and the second connector 202 are respectively provided with mutually cooperating latches, such as mutually meshing toothed latches. The second locking member 203 is used to pass through the first connector 201 and lock onto the second connector 202. For example, the second locking member 203 is a bolt. The second connector 202 is provided with a threaded hole. Through the cooperation of the bolt and the threaded hole, the mutually cooperating latches between the first connector 201 and the second connector 202 can be locked, thereby fixing the folding angle.

[0137] In actual operation, the folding structure has a first state and a second state. In the first state, the connection between the second locking member 203 and the second connecting member 202 is released, and there is a gap between the latch of the first connecting member 201 and the latch of the second connecting member 202, so that the folding angle can be adjusted arbitrarily. In the second state, the latch of the first connecting member 201 and the latch of the second connecting member 202 cooperate with each other to lock together, and the second locking member 203 passes through the first connecting member 201 and locks onto the second connecting member 202 to fix the folding angle.

[0138] The user can loosen the bolts to create a gap between the latches of the first connector 201 and the second connector 202, allowing for arbitrary adjustment of the folding angle. Once the folding angle is determined, the latches of the first connector 201 and the second connector 202 are engaged and locked together. The bolt passes through the first connector 201 and locks onto the threaded hole of the second connector 202 to fix the folding angle.

[0139] In some other embodiments, the support mechanism 20 includes at least two freely assembleable support modules. In other embodiments, the support mechanism 20 is a multi-joint hinge structure, specifically employing a double-hinge + slide rail system.

[0140] In some embodiments, the processor is mounted on the fixed mechanism 19 or the support mechanism 20, and the processor is communicatively connected to each infrared sensor. For example, the processor is an MCU (Microcontroller Unit). The MCU used here is merely an example and is not intended to limit this application; other types of processors are also possible. It should be noted that the communication connection described throughout this document refers to either a wired electrical connection or a wireless communication connection.

[0141] In some embodiments, such as Figure 4As shown, the ankle pump exercise training device also includes a temperature-measuring infrared sensor 23. The temperature-measuring infrared sensor 23 is located at the other end of the support mechanism 20 or at the bottom of the connection between the first telescopic measuring element 10 and the second telescopic measuring element 11. The temperature-measuring infrared sensor 23 is communicatively connected to the processor. The temperature-measuring infrared sensor 23 is used to detect infrared radiation from the patient's dorsum of the foot to generate a sensing signal. The processor is also used to process the sensing signal to obtain the patient's body temperature, thereby providing timely warnings of potential sports injuries such as local inflammation or edema caused by excessive exercise, achieving fatigue risk warning, and ensuring patient safety. For example, the temperature-measuring infrared sensor 23 can be a passive infrared sensor.

[0142] In some embodiments, such as Figure 3 and Figure 4 As shown, the ankle pump exercise training device also includes a display 24, which is mounted on the fixing mechanism 19 or the support mechanism 20. The processor is communicatively connected to the display 24. Understandably, the processor and storage device are integrated with the display 24, or the processor and storage device are set separately from the display 24. The display 24 is used to display at least one of the following: the patient's body temperature, standard parameters of ankle flexion and extension, training parameters of ankle flexion and extension, standard parameters of ankle circumduction, training parameters of ankle circumduction, number of ankle flexion and extension movements, and number of ankle circumduction movements. Understandably, at least one can be one, two, or three items.

[0143] In some embodiments, such as Figure 3 and Figure 4 As shown, the ankle pump exercise training device also includes a reset unit 25, which is mounted on the fixing mechanism 19 or the support mechanism 20. The reset unit 25 is communicatively connected to the processor and is used to reset the data processed by the processor, facilitating reprocessing for each training session. For example, the reset unit 25 may be a reset button, or it may be integrated with the display 24, and triggered by touch operation on the display 24.

[0144] In some embodiments, such as Figure 3 and Figure 4As shown, the ankle pump exercise training device also includes a first switch unit 26 and a second switch unit 27. The first switch unit 26 and the second switch unit 27 are mounted on the fixing mechanism 19 or the support mechanism 20. The first switch unit 26 is used to control the switching of the first infrared sensor 13 and the second infrared sensor 14 (or the first infrared sensor 13, the second infrared sensor 14, the third infrared sensor 17, and the fourth infrared sensor 18). The second switch unit 27 is used to control the switching of the temperature measuring infrared sensor 23. For example, the first switch unit 26 and the second switch unit 27 can be buttons, or the first switch unit 26, the second switch unit 27, and the display 24 can be integrated into one unit, and the first switch unit 26 and the second switch unit 27 can be controlled by touch operation on the display 24.

[0145] In some embodiments, such as Figure 3 and Figure 4 As shown, the ankle pump exercise training device also includes a prompter 28, which is mounted on the fixing mechanism 19 or the support mechanism 20. The prompter 28 is communicatively connected to the processor. When the processor receives a signal, it triggers the prompter 28 to provide a reminder, including an audible and visual reminder. For example, the prompter 28 can be an audible and visual alarm, or it can provide a reminder through a screen display on the monitor 24 and / or sound.

[0146] The above describes the design for the positioner 12, the telescopic measuring element, and the array-type infrared sensor. The following describes the design for the pressure sensor 29, as detailed below:

[0147] like Figure 6 As shown, in some other embodiments, the ankle pump exercise training device also includes a pressure sensor 29, which is communicatively connected to the processor. The pressure sensor 29 is used to capture pressure information of the sole of the foot in real time, so that the processor can analyze the pressure information to obtain pressure characteristics.

[0148] In some embodiments, the ankle pump exercise training device further includes a fixing mechanism 19 and a support mechanism 20. The fixing mechanism 19 is used to fix it to an external fastener, and the pressure sensor 29 is rotatably connected to the other end of the support mechanism 20.

[0149] Specifically, before training, the fixation mechanism 19 is fixed to an external fastener (such as the foot of the bed), and the patient's foot is naturally placed flat on the pressure sensor 29. The patient performs preset standard ankle dorsiflexion, ankle plantarflexion, and ankle circumduction movements. These preset standards can be changed according to the patient's physical condition or the doctor's requirements. At the same time, the pressure sensor 29 captures the pressure information of the foot in real time and uploads the pressure information to the processor. The processor analyzes the pressure information to obtain the standard pressure characteristics of dorsiflexion, plantarflexion, and circumduction.

[0150] After pre-setting the standard pressure characteristics for dorsiflexion, plantar flexion, and circumduction, training begins. Patients perform ankle dorsiflexion, plantar flexion, and circumduction exercises independently. Pressure sensor 29 captures real-time pressure information from the sole of the foot and uploads it to the processor. The processor analyzes the pressure information to obtain the pressure characteristics for dorsiflexion, plantar flexion, and circumduction training. When the matching degree between the dorsiflexion training pressure characteristic and the standard dorsiflexion pressure characteristic reaches a first preset value, and the matching degree between the plantar flexion training pressure characteristic and the standard plantar flexion pressure characteristic reaches a second preset value, the ankle flexion-extension exercise is considered a qualified movement, and the count is incremented by 1. When the matching degree between the circumduction training pressure characteristic and the standard circumduction pressure characteristic reaches a third preset value, the ankle circumduction exercise is considered a qualified movement, and the count is incremented by 1. This method ensures standardized movements while achieving precise quantification of movement range and number of repetitions, improving functional training effectiveness, facilitating rehabilitation effect assessment, and the counting error rate of this method is ≤±3%.

[0151] In some embodiments, such as Figure 6 As shown, the ankle pump exercise training device also includes an adjustment mechanism 21. The pressure sensor 29 is rotatably connected to the other end of the support mechanism 20 through the adjustment mechanism 21. The adjustment mechanism 21 is used to adjust the orientation of the pressure sensor 29.

[0152] For example, such as Figure 5 As shown, the steering mechanism 21 is a universal joint, which comprises a first U-shaped fork 211, a second U-shaped fork 212, a cross shaft 213, bearings 214, and a first locking member 215. The first U-shaped fork 211 and the second U-shaped fork 212 are connected together by the cross shaft 213. Bearings 214 are respectively installed at the ends of the cross shaft 213. The first locking member 215 is used to lock the cross shaft 213 at both ends of the first U-shaped fork 211 and / or the second U-shaped fork 212. The first U-shaped fork 211 is rotatably connected to the other end of the support mechanism 20, and the second U-shaped fork 212 is fixedly connected to the pressure sensor 29. When the shaft at either end rotates, it will drive the other shaft to rotate. At the same time, due to the presence of the bearings 214, it can swing around the center of the cross shaft 213 at a certain angle, realizing stepless adjustment. For example, the first locking element 215 is a bolt, and the first U-shaped shaft fork 211 and / or the second U-shaped shaft fork 212 have threaded holes at both ends. The bolt locks the cross shaft 213 through frictional contact with the cross shaft 213. In actual operation, when it is necessary to adjust the direction, the bolt can be loosened to separate it from the cross shaft 213. After adjusting the direction by rotation, the bolt can be tightened again to make it frictionally contact the cross shaft 213.

[0153] In some embodiments, such as Figure 6As shown, the fixing mechanism 19 is a fixing clip that can be clipped to the foot of the bed or other places. The fixing clip and foot of the bed mentioned here are just examples and are not intended to limit this application. Others are also possible.

A folding structure is provided between each pair of rod segments. The folding structure includes a first connector 201, a second connector 202, and a second locking member 203. The first connector 201 is connected to one of the rod segments, and the second connector 202 is connected to the other rod segment. The first connector 201 and the second connector 202 are respectively provided with mutually cooperating latches, such as mutually meshing toothed latches. The second locking member 203 is used to pass through the first connector 201 and lock onto the second connector 202. For example, the second locking member 203 is a bolt. The second connector 202 is provided with a threaded hole. Through the cooperation of the bolt and the threaded hole, the mutually cooperating latches between the first connector 201 and the second connector 202 can be locked, thereby fixing the folding angle.

[0155] In actual operation, the folding structure has a first state and a second state. In the first state, the connection between the second locking member 203 and the second connecting member 202 is released, and there is a gap between the latch of the first connecting member 201 and the latch of the second connecting member 202, so that the folding angle can be adjusted arbitrarily. In the second state, the latch of the first connecting member 201 and the latch of the second connecting member 202 cooperate with each other to lock together, and the second locking member 203 passes through the first connecting member 201 and locks onto the second connecting member 202 to fix the folding angle.

[0156] The user can loosen the bolts to create a gap between the latches of the first connector 201 and the second connector 202, allowing for arbitrary adjustment of the folding angle. Once the folding angle is determined, the latches of the first connector 201 and the second connector 202 are engaged and locked together. The bolt passes through the first connector 201 and locks onto the threaded hole of the second connector 202 to fix the folding angle.
