Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent interactive foot pump suitable for post-operative arthritis surgery. Background Art

[0002] After joint surgery (such as knee replacement, hip replacement, etc.), the patient's recovery process is crucial and faces many challenges. On the one hand, long-term bed rest after surgery significantly slows blood circulation in the lower limbs and greatly increases the risk of deep vein thrombosis (DVT). On the other hand, the recovery of joint function requires patients to perform a series of specific rehabilitation exercises, such as toe hooks and leg lifts, to enhance muscle strength, improve joint mobility, and further promote blood circulation to assist in the healing and recovery of the surgical site.

[0003] At present, the foot pumps commonly used in clinical practice have played a certain role in preventing DVT, but they have significant defects. First, their functions are single and only focus on pressure massage of the soles of the feet. They fail to organically combine with the rehabilitation training of hooking feet and raising legs, which is necessary for patients after joint surgery, and cannot provide comprehensive rehabilitation support for patients. Secondly, the existing foot pumps lack an effective monitoring and feedback mechanism for patients' rehabilitation training movements. In the actual rehabilitation process, it is difficult for medical staff to accurately grasp the key information such as the accuracy, standardization, number and amplitude of patients' hooking feet and raising legs, which makes it impossible for them to give patients targeted guidance and adjust rehabilitation plans in time, greatly affecting the rehabilitation effect and treatment process. Furthermore, patients after joint surgery usually experience discomfort symptoms such as swelling and pain in their limbs, and the physical conditions, surgical sites and recovery conditions of different patients vary greatly. However, the existing foot pumps perform poorly in terms of wearing comfort and personalized adaptation. For example, the fixing method is not flexible enough and cannot be adjusted according to the degree of limb swelling; the pressure and temperature regulation is not accurate enough to meet the diverse needs of patients at different stages after surgery, resulting in low patient compliance and difficulty in continuous and effective thrombosis prevention and rehabilitation training.

[0004] In summary, the development of an intelligent interactive foot pump that can overcome the above problems and integrate thrombosis prevention, rehabilitation training assistance, motion monitoring and feedback, and comfortable personalized adaptation has important clinical significance and practical needs for the rehabilitation of patients after joint surgery. Summary of the invention

[0005] In view of this, the present invention aims to propose an intelligent interactive foot pump suitable for post-operative arthritis surgery, by setting an integrated structure including sole support, pressure regulation, temperature regulation, elastic drawstring, control circuit board, shell and comfortable lining, wherein the pressure regulation component accurately controls the sole pressure, the temperature regulation component maintains a suitable temperature, the elastic drawstring component assists and monitors rehabilitation movements, the control circuit board coordinates the operation of various components, the shell component ensures the stability and sealing of the equipment, and the comfortable lining improves wearing comfort, so as to solve the problems of existing foot pumps in post-operative arthritis surgery, such as single function, lack of motion monitoring feedback, insufficient comfort and personalization, and difficulty for medical staff to accurately manage the patient's rehabilitation process.

[0006] The present invention is achieved through the following technical solutions:

[0007] A smart interactive foot pump suitable for post-arthritis surgery includes a sole support structure, a pressure regulating component is fixedly arranged at the rear end of the sole support structure, a temperature regulating component is fixedly arranged on the upper surface of the sole support structure, an elastic drawstring component is fixedly arranged at the upper edge of the front end of the sole support structure, and a control circuit board is fixedly arranged on the outer side of the sole support structure. The control circuit board is connected to the pressure regulating component, the temperature regulating component and the elastic drawstring component through lines.

[0008] Furthermore, the bottom of the sole supporting structure is provided with anti-slip patterns, the upper surface of the sole supporting structure is provided with circular grooves, the bottom of the grooves is provided with ventilation holes, the edge of the sole supporting structure is surrounded by a flexible rubber sealing edge, and the interior of the sole supporting structure is provided with a wire groove, a fixing column and a battery fixing frame.

[0009] Furthermore, the pressure regulating assembly includes a high-precision pressure sensor arranged in the groove, a micro air pump installed at the bottom of the rear end of the sole support structure and connected through a shock-absorbing rubber pad, a gas shunt tube connected to the air outlet of the micro air pump, and an air bag distributed on the upper surface of the sole support structure and connected to the branch interface of the gas shunt tube.

[0010] Furthermore, the temperature adjustment component includes a thermoelectric cooling sheet evenly distributed in the groove below the pressure sensor and bonded to the sole support structure through a thermally conductive silicone sheet, a heating wire wound in the wire groove, a temperature sensor installed in the groove close to the thermoelectric cooling sheet and the heating wire, and a heat sink installed on the outside of the bottom of the sole support structure and connected to the cold surface of the thermoelectric cooling sheet, and the wire groove is filled with insulating thermally conductive material.

[0011] Furthermore, the elastic drawstring assembly includes a drawstring, one end of which is fixed to the upper edge of the front end of the sole support structure through a metal ring, and the other end of the drawstring passes through a drawstring adjustment buckle with a scale mark, and the drawstring adjustment buckle is connected to a fixing strap with Velcro at one end, and an acceleration sensor and a gyroscope sensor are respectively installed at the connection between the drawstring and the sole support structure and the drawstring adjustment buckle.

[0012] Furthermore, the control circuit board includes a microprocessor, a signal processing module, a pressure control module, a temperature control module, a wireless communication module and a power management module.

[0013] Furthermore, a shell assembly is fixedly arranged on the top of the sole supporting structure, and the shell assembly includes an ergonomically designed upper cover with a transparent observation window and a lower cover with a card slot, a protrusion and a sealing groove inside. The upper cover and the lower cover are connected by screws, and the flexible rubber sealing edge is fixedly arranged inside the sealing groove.

[0014] Furthermore, a lining component is fixedly arranged inside the outer shell component, and the lining component includes an insole fixed to the upper surface of the sole support structure by glue, massage protrusions arranged on the surface of the insole, and a buffer pad adhered to the inner edge of the outer shell component and the contact part with the patient's limbs.

At the same time, the equipment can receive updated data, maintain the optimal state of performance and data accuracy, and improve the overall rehabilitation service level.

[0035] like Figure 1-6 As shown, an embodiment of the present invention is: an intelligent interactive foot pump suitable for post-arthritis surgery, mainly composed of a sole support structure 1, a pressure regulating component 2, a temperature regulating component 3, an elastic drawstring component 4, a control circuit board 5, a shell component 6 and a comfortable lining component 7.

[0036] The sole support structure 1 is the basic bearing component of the entire sole pump, and the anti-slip texture on the bottom (the depth of the texture is 0.5

[0037] -1 mm) can effectively prevent the patient from slipping during use of the foot pump, ensuring safe use. The circular groove 101 (groove depth of about 3-5 mm, diameter of 10-15 mm) distributed on the upper surface is used to place the pressure sensor and some temperature adjustment components. The vent 102 (diameter 1-2 mm) at the bottom of the groove ensures gas circulation, which is conducive to uniform regulation of pressure and temperature. The flexible rubber sealing edge 103 (width 3-5 mm, height 4-6 mm) surrounding the edge fits tightly with the outer shell component 6 to prevent dust and moisture from entering, and at the same time plays a buffering role to avoid pressure on the patient's feet. The internal wire groove 104 (wire groove width 2-3 mm, depth 1-2 mm) is used to regularly arrange various lines, the fixing column 105 (diameter 3-5 mm, height 5-8 mm) is used to firmly install the control circuit board 5, and the battery fixing frame 106 is made of plastic material and is used to stably fix the rechargeable lithium battery (battery capacity 1000-2000 mAh) to ensure that the battery provides stable power for the entire device, and the positive and negative poles of the battery are reliably connected to the power management module 506 of the control circuit board 5 through wires.

[0038] In the pressure regulating component 2, a high-precision pressure sensor 201 (a semiconductor pressure sensor is used, with a diameter of 5-8 mm and a thickness of 2-3 mm) is installed in the circular groove 101 of the sole support structure 1 and is tightly fixed with special glue. Its signal output line is connected to the signal processing module 502 of the control circuit board 5 through the wire groove 104 of the sole support structure 1 to ensure accurate perception of plantar pressure changes and stable data transmission. The micro air pump 202 (driven by a brushless DC motor, with an overall size of 40-60 mm long × 30-40 mm wide × 20-30 mm high) is installed at the bottom of the rear end of the sole support structure 1 and is connected to the sole support structure 1 through a shock-absorbing rubber pad 205 (thickness 3-5 mm) to reduce the impact of vibration on the patient and interference with other components. The air filter 206 connected to the air inlet can effectively filter impurities in the air to ensure that the air entering the airbag is clean. The air outlet is connected to the gas diversion tube 203 (made of medical silicone, with an inner diameter of 3

[0039] -5 mm, outer diameter 4-6 mm), the branch interface 207 of the gas shunt tube is connected to the airbag 204 distributed on the upper surface of the sole support structure 1 through a sealing joint. The airbag (made of high-strength, soft medical rubber material, with a wall thickness of 1-2 mm) is composed of multiple independent small air chambers, which are designed according to the pressure distribution area of ​​the sole. After inflation, it can fit closely to different parts of the sole, achieve precise pressure massage, prevent thrombosis, and can adjust the pressure distribution in real time according to the patient's rehabilitation training movements such as hooking the foot and raising the leg.

[0040] In the temperature regulating component 3, the thermoelectric cooling sheet 301 (made of semiconductor thermoelectric material, with dimensions of 20-30 mm long × 15-20 mm wide × 3-5 mm high, 3-5 pieces in total) is evenly distributed in the circular groove 101 and is located below the pressure sensor 201. It is tightly fitted with the sole supporting structure 1 through a thermally conductive silicone sheet 305 (1-2 mm thick) to ensure good heat conduction effect. Its cold surface dissipates heat through an aluminum alloy heat sink 304 (wavy, 2-3 mm thick, and 50-100 square centimeters in surface area). The heat sink is installed on the outside of the bottom of the sole supporting structure 1, fixed with screws and coated with thermally conductive silicone grease to enhance the heat dissipation effect. The heating wire 302 (made of nickel-chromium alloy) is wound in the wire groove 104 of the sole support structure 1, and the wire groove is filled with high-temperature resistant insulating thermal conductive material 306 to ensure that the heat generated by the heating wire is evenly transferred to the upper surface of the sole support structure 1. The heating wire is connected to the temperature control module 504 of the control circuit board 5 through a wire, and the wire is wrapped with a high-temperature resistant insulating sleeve to prevent short circuit and leakage. The temperature sensor 303 (a high-precision thermistor sensor, cylindrical in shape, 3-5 mm in diameter, 5-8 mm in length, 3-5 in total) is installed in the circular groove 101 near the thermoelectric cooling plate 301 and the heating wire 302 to monitor the temperature change of the sole support structure 1 in real time. Its signal output line is connected to the temperature control module 504 through the wire groove 104, and is arranged separately from the signal output line of the pressure sensor 201 to avoid signal interference. The temperature control module 504 uses a PID control algorithm to accurately control the working state of the thermoelectric cooling plate 301 and the heating wire 302 according to the preset temperature range (35°C-42°C) and feedback data, so as to provide patients with a suitable warm environment, promote blood circulation and relieve pain.

[0041] The elastic drawstring assembly 4 includes two high-strength medical elastic drawstrings 401 (length 300-500 mm, diameter 3-5 mm), one end of which is fixed to the upper edge of the front end of the sole support structure 1 through a metal ring 404 (diameter 5-8 mm), and the metal ring is integrally molded with the sole support structure 1 by injection molding to ensure a firm connection and flexible rotation of the drawstring. The other end of the drawstring passes through a drawstring adjustment buckle 402 (plastic material, adjustment range 200-400 mm), and the drawstring adjustment buckle is connected to a cotton fixing belt 403 (width 20-30 mm, length 400-600 mm), and a Velcro 405 is provided at one end of the fixing belt, which is convenient for the patient to wrap the fixing belt around the calf or thigh and fix it, providing appropriate resistance and auxiliary support when hooking the foot and lifting the leg, while ensuring comfort. A miniature MEMS acceleration sensor 406 and a gyroscope sensor 407 (with dimensions of 5-8 mm in length × 3-5 mm in width × 2-3 mm in height) are installed at the connection between the drawstring 401 and the sole support structure 1 and the drawstring adjustment buckle 402, respectively. They are connected to the signal processing module 502 of the control circuit board 5 through a thin data cable (outer diameter 1-2 mm). The data cable is arranged along the drawstring 401 and the wire groove 104 to avoid being exposed and affecting its use. The sensor can accurately collect the drawstring movement data, provide data support for the microprocessor (MCU) 501 to analyze the patient's rehabilitation training movements, realize real-time monitoring and feedback guidance, and help patients correct irregular movements.

[0042] The control circuit board 5 is made by multi-layer printed circuit board (PCB) technology, with a size of 60-80 mm long × 40-60 mm wide. It is fixed on the fixing column 105 of the sole support structure 1 by screws, and integrates the main functional modules such as microprocessor (MCU) 501 (using high-performance ARM core processor), signal processing module 502, pressure control module 503, temperature control module 504, wireless communication module 505 (using Bluetooth and Wi-Fi dual-mode communication chip) and power management module 506. The microprocessor (MCU) 501 is responsible for the control logic and data processing of the entire foot pump, coordinates the work of each module, collects, analyzes and sends control instructions for data from each sensor, and is the core of the system. The signal processing module 502 amplifies, filters and converts the sensor signal into analog and digital signals and transmits it to the microprocessor (MCU) 501. The pressure control module 503 controls the micro air pump 202 to work according to the instructions of the microprocessor (MCU) 501 to achieve precise adjustment of the foot pressure. The temperature control module 504 controls the operation of the thermoelectric cooling sheet 301 and the heating wire 302 according to the feedback data of the temperature sensor 303 to maintain a suitable temperature. The wireless communication module 505 realizes the data transmission between the foot pump and external devices (such as the patient's smartphone, hospital rehabilitation management system). The patient can view the working status, set parameters and receive rehabilitation training suggestions through the smartphone APP. Medical staff can remotely monitor the patient's usage and obtain rehabilitation data in order to adjust the treatment plan and rehabilitation training plan. The power management module 506 is responsible for power management and distribution, including charging control, battery power monitoring and low power alarm functions to ensure stable power supply for the equipment.

[0043] The shell assembly 6 includes an ergonomically designed upper cover 601 with a transparent observation window 603 (made of polycarbonate material, 2-3 mm thick) and a lower cover 602 with a card slot 604, a protrusion 605 and a sealing groove 606 inside. The upper cover and the lower cover are connected by screws (specification M3-M4). The sealing groove 606 is used to install a flexible rubber sealing edge 103 to ensure the overall firmness and sealing of the shell and protect the internal components. At the same time, the ergonomic design makes it more comfortable for patients to wear. The transparent observation window 603 is convenient for patients to view the internal working conditions of the foot pump and for medical staff to perform equipment maintenance inspections.

[0044] The comfort lining component 7 contains an insole 701 (made of medical silicone material, 3-5 mm thick) fixed to the upper surface of the sole support structure 1 by glue. The surface of the insole is designed with massage protrusions 703, which are arranged according to the distribution of acupuncture points on the sole of the foot. When the patient uses the foot pump, the acupuncture points on the sole of the foot can be massaged to promote blood circulation and relieve fatigue and pain. The buffer pad 702 (made of highly elastic polyurethane foam material, 4-6 mm thick) pasted on the inner edge of the shell component 6 and the contact part of the patient's limbs can effectively reduce the pressure and friction of the shell on the patient's limbs, improve wearing comfort, ensure that the patient can use the foot pump for a long time and stably for rehabilitation training, and improve the effect and compliance of rehabilitation training.

[0045] In actual use, after the patient undergoes joint surgery, the medical staff first sets the initial parameters of the foot pump through a smartphone APP or a hospital rehabilitation management system according to the patient's surgery type, physical condition, and rehabilitation stage, such as the pressure adjustment range, temperature setting value, rehabilitation training plan (including the target number, frequency, and amplitude of the toe hook and leg lift movements, etc.) and basic patient information. After the settings are completed, the information is transmitted to the microprocessor (MCU) 501 on the control circuit board 5 of the foot pump through the wireless communication module 505, and the microprocessor (MCU) 501 initializes the configuration of each functional module according to the preset parameters. The patient puts the foot into the foot pump so that the sole is in full contact with the insole 701, and then uses the fixing belt 403 of the elastic drawstring assembly 4 to fix the foot pump on the calf, and adjusts the length of the drawstring 401 to a suitable position through the drawstring adjustment buckle 402 to ensure that it is firmly fixed and comfortable. After turning on the power switch of the foot pump, the intelligent pressure regulation system and the intelligent temperature regulation system are first started, and the pressure sensor 201 and the temperature sensor 303 monitor the data in real time and transmit it to the control circuit board 5. Each control module controls the micro air pump 202, the thermoelectric cooling sheet 301 and the heating wire 302 to work according to the data and preset parameters, so that the sole of the foot is subjected to appropriate pressure massage and temperature stimulation, promoting blood circulation and relieving pain. When the patient performs the rehabilitation training of hooking the foot and raising the leg, the elastic drawstring assembly 4 plays a role, the drawstring 401 generates resistance to assist the action, and the acceleration sensor 406 and the gyroscope sensor 407 collect the drawstring movement data and transmit it to the control circuit board 5. The microprocessor (MCU) 501 compares and analyzes the data with the preset standard action model to evaluate the accuracy and standardization of the action. If a deviation is found, the wireless communication module 505 sends guidance information to the patient's smartphone APP, telling the patient how to adjust the action in voice or text form, such as "hook the foot angle a little larger, keep the foot hooking at a constant speed", etc. At the same time, the microprocessor (MCU) 501 can also dynamically adjust the parameters of the pressure regulation system and the temperature regulation system according to the action situation to better meet the needs of rehabilitation training. During use, the control circuit board 5 of the foot pump transmits the patient's use data to the smartphone APP or the hospital rehabilitation management system in real time through the wireless communication module 505. Medical staff can monitor remotely. If abnormal rehabilitation data is found, such as sudden changes in pressure, abnormal temperature, substandard movements, etc., they can communicate with the patient in time and adjust the rehabilitation training plan or foot pump parameters to ensure a safe and effective rehabilitation process. After the patient has finished using it, turn off the power switch, untie the fixing belt 403, take out the foot, clean and maintain the foot pump, regularly check the wear of each component, and replace it in time if damaged to ensure normal use next time, so as to provide patients with continuous reliable rehabilitation support.

[0046] When implementing this embodiment, the following steps are performed:

[0047] Wearing the device

[0048] First, the rear end of the sole support structure 1 is placed under the sole of the patient's foot, so that the upper surface of the sole support structure 1 is in full contact with the sole, ensuring that the pressure sensor 201 and the temperature adjustment component 3 and other components can accurately sense the state of the sole. Then, the fixing belt 403 of the elastic drawstring assembly 4 is wrapped around the appropriate position of the calf or thigh (determined according to the patient's surgical site and rehabilitation needs, generally within 10-15 cm above and below the knee), and the Velcro 405 is firmly pasted, but avoids too tight compression on the limbs. Next, adjust the drawstring adjustment buckle 402, and adjust the high-strength medical elastic drawstring 401 to a suitable length (usually between 30-50 cm) according to the patient's comfort and limb activity needs, ensuring that the drawstring 401 can provide appropriate resistance-assisted training when performing hooking and leg lifting movements, and will not restrict the normal progress of the movement. During the entire rehabilitation training process, it is necessary to ensure that the position of the foot pump is stable, and there will be no obvious displacement or shaking, so as to ensure that each component can accurately collect data and perform corresponding functions, and provide stable and effective rehabilitation support for patients.

[0049] Training parameter settings

[0050] After turning on the device, enter the parameter setting interface through the smartphone APP connected to the foot pump wirelessly. First, enter the patient's personal information, including name, age, gender, surgery type, surgery time, physical condition (such as whether there are underlying diseases such as hypertension and diabetes), and other detailed information. This information will be stored in the data storage and transmission module of the control circuit board 5 (similar to the corresponding module in the above device) to provide basic data support for subsequent personalized rehabilitation training.

[0051] Then, according to the patient's specific condition and rehabilitation stage, choose the appropriate initial training program. For example, for patients in the early postoperative period, a milder rehabilitation training mode can be selected, with the pressure adjustment set at a lower level (the airbag pressure is generally between 20-30 mmHg), the temperature set at 35-37°C, and the amplitude and frequency of the foot-twisting and leg-lifting movements are also relatively low (the foot-twisting angle is 10-20 degrees, the leg-lifting height is 10-15 cm, and 5-10 times per minute); for patients in the middle stage of rehabilitation, gradually increase the pressure (airbag pressure 30-40 mmHg), temperature (37-39°C), and the amplitude and frequency of the movements (foot-twisting angle 20-30 degrees, leg-lifting height 15-20 cm, 10-15 times per minute); for patients in the late stage of rehabilitation, further increase the training intensity to approach the normal activity level (airbag pressure 40-50 mmHg, temperature 39-42°C, foot-twisting angle 30-40 degrees, leg-lifting height 20-25 cm, 15-20 times per minute). At the same time, parameters such as training time (generally 20-30 minutes per training, 2-3 times a day), rest interval, etc. can also be set. These initial setting information will be transmitted to the microprocessor (MCU) 501 on the control circuit board 5 of the foot pump through the wireless communication module 505. The microprocessor (MCU) 501 initializes the pressure control module 503, the temperature control module 504 and other related functional modules according to these preset parameters to ensure that the foot pump can work according to the personalized needs of the patient.

[0052] Stress and temperature regulation training

[0053] Before the pressure regulating component 2 is started, the microprocessor (MCU) 501 sends an initialization instruction to the micro air pump 202 according to the preset training parameters. The micro air pump 202 is started according to the instruction and inflates the air bag 204 through the gas shunt tube 203. The pressure sensor 201 monitors the pressure of the sole of the foot in real time, and transmits the pressure data to the signal processing module 502 on the control circuit board 5. The signal processing module 502 amplifies, filters and converts the pressure data into analog and digital data, and then transmits it to the microprocessor (MCU) 501. The microprocessor (MCU) 501 accurately controls the inflation volume and inflation speed of the micro air pump 202 according to the preset pressure parameters and feedback data, so that the sole of the foot is subjected to moderate pressure massage, the pressure distribution is uniform and meets the personalized needs of the patient, effectively promotes the blood circulation of the sole of the foot, and prevents thrombosis. For example, when the patient's foot curls and the pressure on the front of the sole increases, the microprocessor (MCU) 501 will correspondingly increase the inflation speed and amount of the airbags in the front of the sole to maintain a stable massage pressure while avoiding discomfort to the patient due to sudden changes in pressure; when lifting the legs, the air pump will also adaptively fine-tune the pressure of each airbag according to the overall pressure change to ensure that the sole of the foot can receive uniform and appropriate pressure massage throughout the rehabilitation training process. This pressure regulation mechanism that is closely integrated with rehabilitation training movements can better promote blood circulation, enhance the effect of rehabilitation training, and provide strong support for the rehabilitation of patients after arthritis surgery.

[0054] At the same time, the temperature adjustment component 3 also starts working. The temperature sensor 303 monitors the temperature of the sole support structure 1 and transmits the temperature data to the temperature control module 504. The temperature control module 504 uses the PID control algorithm to control the working state of the thermoelectric cooling sheet 301 and the heating wire 302 according to the preset temperature range (such as 35-42°C) and the feedback data. When the temperature is lower than the preset lower limit, the heating wire 302 starts working, generates heat and transmits it to the sole through the sole support structure 1; when the temperature is higher than the preset upper limit, the thermoelectric cooling sheet 301 starts the cooling function to reduce the temperature. During the whole process, the temperature control module 504 continuously adjusts the power of the thermoelectric cooling sheet 301 and the heating wire 302 to keep the temperature of the sole support structure 1 within a suitable range, providing a comfortable warm environment for the patient, further promoting blood circulation and relieving pain, especially in a cold environment or when the patient's limb blood circulation is poor, the heating function can effectively improve the blood circulation of the sole, improve the patient's comfort and rehabilitation effect.

[0055] Assisted training of toe hook and leg lift

[0056] When the patient starts to perform rehabilitation training of toe hooking and leg lifting, the elastic pull rope assembly 4 comes into play. During the toe hooking action, the patient's feet are hooked upwards, and the elastic pull rope 401 is stretched, generating resistance in the opposite direction of the toe hooking. The acceleration sensor 406 and the gyroscope sensor 407 installed on the elastic pull rope 401 monitor the changes in the motion state of the pull rope in real time, including parameters such as acceleration, angular velocity and angle, and transmit these data to the signal processing module 502 on the control circuit board 5 through the data line. After the signal processing module 502 processes the data, it is transmitted to the microprocessor (MCU) 501. The microprocessor (MCU) 501 compares and analyzes these data with the preset standard toe hooking action model to evaluate the accuracy and standardization of the patient's toe hooking action. If it is found that the patient's foot-hooking action has deviations, such as too small an angle, too fast or uneven speed, etc., the microprocessor (MCU) 501 will send the corresponding guidance information to the patient's smartphone APP through the wireless communication module 505, and tell the patient how to adjust the foot-hooking action in the form of voice prompts or text displays, such as "hook the foot at a larger angle and keep hooking the foot at a constant speed." At the same time, the microprocessor (MCU) 501 can also dynamically adjust the working parameters of the pressure regulation system and the temperature regulation system according to the patient's foot-hooking action to better adapt to the patient's physical changes and needs during rehabilitation training. In the leg-lifting action, the elastic pull rope 401 also generates corresponding tension according to the height and speed of the patient's leg-lifting to help the patient stabilize the leg-lifting action. At the same time, the action monitoring sensor transmits data to the microprocessor (MCU) 501, and the microprocessor (MCU) 501 performs similar analysis and feedback to ensure that the patient's leg-lifting action is standardized and effective, promote the contraction of the thigh muscles and blood circulation, and enhance the stability and mobility of the joints.

[0057] Training data collection and analysis

[0058] During the whole training process, the pressure sensor 201 continuously collects the plantar pressure data, the temperature sensor 303 monitors the temperature data of the sole support structure 1 in real time, and the acceleration sensor 406 and the gyroscope sensor 407 continuously collect the motion parameter data of the hooking and leg lifting movements. These data are firstly amplified, filtered and analog-to-digital converted (if necessary) at their respective sensor ends, and then transmitted to the signal processing module 502 on the control circuit board 5 by wired or wireless means (such as wireless communication technologies such as Bluetooth or low-power Wi-Fi). The signal processing module 502 further processes these data, such as removing noise interference, data fusion (integrating data from different sensors to obtain more comprehensive information), feature extraction (extracting key parameters that can reflect the patient's rehabilitation status and movement characteristics), etc., and then transmits the processed signals to the microprocessor (MCU) 501.

[0059] The microprocessor (MCU) 501 performs a comprehensive analysis of all received data and compares it with the preset normal rehabilitation mode database. The normal rehabilitation mode database is established through the accumulation of data from a large number of patients undergoing joint surgery during rehabilitation, and contains standard parameter ranges for various rehabilitation training movements at different stages, such as the amplitude, speed, acceleration, plantar pressure distribution, temperature change curve, etc. when hooking the foot and lifting the leg. The microprocessor (MCU) 501 determines through comparative analysis whether the patient's rehabilitation movements are accurate and coordinated, whether the pressure and temperature regulation are appropriate, whether the body condition is stable, etc., and generates a training result evaluation report based on the analysis results, which is stored in the data storage and transmission module 506 of the control circuit board 5, and can also be displayed on the smartphone APP for patients or medical staff to view through the wireless communication module 505.

[0060] Human-computer interaction and training feedback

[0061] Smartphone APP plays an important role in human-computer interaction during the training process. The APP interface displays the patient's training progress (such as completed training time, remaining time, completed number of toe hooks and leg lifts, target number, etc.), physiological data feedback (such as intuitive charts or numerical information such as plantar pressure change curves, temperature change curves, movement amplitude and speed charts), and training result evaluation reports (such as the analysis results of indicators such as the accuracy and coordination of the patient's toe hooks and leg lifts, as well as the pressure and temperature regulation effects in the form of text and charts), so that patients and medical staff can intuitively understand the training situation.

[0062] The voice prompt and interaction function of the APP synthesizes voice prompt information according to the instructions of the microprocessor (MCU) 501. Before the training begins, the voice prompts the patient to wear the foot pump correctly and adjust the position of the elastic drawstring assembly 4; during the training process, the real-time voice guides the patient to hook the foot and lift the leg. When the patient's movements are wrong or do not meet the requirements, the voice prompts to correct the movements, such as "Your leg lifting speed is too fast, please slow down and keep steady"; after the training, the voice broadcasts the training results and suggestions, such as "This training is completed, your foot hooking coordination has improved, but the plantar pressure in some areas needs to be further optimized and adjusted." In addition, the voice interaction function also has a voice recognition function. Patients can perform some basic operations through voice commands, such as pausing / continuing training, adjusting pressure or temperature parameters, viewing training data, etc., to improve the convenience and humanization of equipment operation.

[0063] Training completion and data transmission

[0064] When the patient completes the scheduled training time or number of training sessions, the foot pump automatically stops working and issues a voice prompt "This training session has ended" through the smartphone APP. At this time, the data storage and transmission module 506 of the control circuit board 5 organizes and stores all physiological data collected during this training (including pressure sensor data, temperature sensor data, motion monitoring sensor data, etc.), training parameters (pressure setting, temperature setting, training mode, amplitude and frequency of toe hooking and leg lifting movements, etc.), and training result evaluation reports generated by the microprocessor (MCU) 501, and classifies and archives them according to patient information and training time, and stores them in the device's built-in storage medium (such as a flash memory chip, etc.). Data storage uses encryption technology to ensure the security of patient information and data integrity, making it convenient for medical staff to retrieve and analyze patients' rehabilitation training data at any time to develop personalized rehabilitation treatment plans or conduct rehabilitation effect evaluations.

[0065] At the same time, the device uploads these data to the hospital's telemedicine server or the medical staff's mobile terminal device (such as a smart phone, tablet computer, etc.) in real time through the wireless communication module 505. During the transmission process, the data will be compressed and encrypted to improve transmission efficiency and ensure data security. In this way, even if the medical staff is not with the patient, they can timely grasp the patient's rehabilitation progress through remote data monitoring, which provides the possibility for remote rehabilitation guidance, breaks the limitations of time and space, improves the utilization efficiency of medical resources, and enables patients to enjoy professional rehabilitation medical services in a home or community environment, promoting the continuity and comprehensiveness of rehabilitation treatment.

[0066] The technical effects of this embodiment are as follows:

[0067] Accurate rehabilitation function realization

[0068] Through the coordinated cooperation of the pressure regulating component 2, the temperature regulating component 3 and the elastic drawstring component 4, and the intelligent regulation of the control circuit board 5, accurate and effective rehabilitation support can be provided for patients after arthritis surgery. The pressure regulating component 2 accurately controls the inflation volume and pressure distribution of the airbag 204, performs personalized pressure massage according to the needs of different areas of the patient's sole, simulates the force of the sole of the foot during normal walking or exercise, promotes blood circulation, prevents thrombosis, and accelerates postoperative rehabilitation. For example, for areas where local swelling of the sole of the foot is more obvious after surgery, the inflation pressure of the corresponding airbag can be increased by controlling the circuit board 5, and the area can be accurately massaged to improve local blood circulation and reduce swelling symptoms. The temperature regulating component 3 accurately maintains the appropriate temperature of the sole support structure 1, and dynamically adjusts it according to the patient's body sensation and rehabilitation needs within the range of 35℃-42℃, creating a comfortable warm environment for the sole, which helps vasodilation, further enhances the blood circulation effect, relieves pain and swelling of the limbs after surgery, and improves the patient's tolerance and compliance to rehabilitation training. The elastic rope assembly 4 provides just the right resistance assistance and standardized guidance for the patient's foot hooking and leg lifting movements. The acceleration sensor 406 and gyroscope sensor 407 installed therein accurately monitor the movement details, including movement speed, angle, acceleration and other parameters, so that the patient can gradually restore the range of motion and muscle strength of the joints during the training process, and at the same time develop correct exercise habits to avoid secondary injuries or poor rehabilitation effects caused by incorrect movements. This precise rehabilitation function design is targeted at the specific needs of patients after joint surgery, and works in combination from multiple aspects to provide strong guarantees for the patient's rehabilitation process.

[0069] Multi-dimensional data collection and analysis

[0070] It integrates a variety of advanced sensors such as high-precision pressure sensor 201, temperature sensor 303, acceleration sensor 406 and gyroscope sensor 407 to collect key data of patients in the process of using the foot pump. The pressure sensor 201 obtains the distribution and change data of the pressure on the sole of the foot in real time and accurately, reflecting the force on the sole of the patient in different postures and movements, and provides a direct basis for evaluating the effect of rehabilitation training and adjusting pressure parameters. The temperature sensor 303 accurately monitors the temperature change of the sole support structure 1 to ensure the accurate operation of the temperature regulation system. At the same time, the temperature data can also be used as an important indicator for evaluating the comfort and physical condition of the patient. The acceleration sensor 406 and the gyroscope sensor 407 collect detailed motion parameters of the patient's hooking and leg lifting movements, and quantify the movement from multiple dimensions such as the amplitude, speed, direction and acceleration of the movement. These rich multi-dimensional data are deeply analyzed by the microprocessor (MCU) 501 of the control circuit board 5, and compared with the preset joint surgery rehabilitation standard database. The database is built based on a large amount of clinical data and rehabilitation cases, covering the normal rehabilitation index range of patients with different types of surgery and different rehabilitation stages, such as the trend of plantar pressure changes, the range of joint movement angles, the muscle strength growth curve, and the temperature adaptation range, etc. Based on this precise data analysis, it is possible to comprehensively and accurately evaluate the patient's rehabilitation status, including whether the rehabilitation progress is in line with expectations, whether the current rehabilitation training program needs to be adjusted, and whether there are potential rehabilitation risks, so as to formulate a more scientific and personalized rehabilitation training plan for the patient and improve the pertinence and effectiveness of rehabilitation treatment.

[0071] Personalized rehabilitation training and real-time feedback

[0072] Relying on the powerful data processing capability and intelligent algorithm of the microprocessor (MCU) 501 in the control circuit board 5, combined with the flexible use of the normal rehabilitation mode database, it is possible to tailor a personalized rehabilitation training program according to the unique condition, physical condition and rehabilitation progress of each patient. During the patient's rehabilitation training, the microprocessor (MCU) 501 monitors the data from each sensor in real time, and quickly analyzes and judges the patient's movement accuracy, coordination, and adaptability of plantar pressure and temperature. For example, when it is found that the patient's angle is not standard or the speed is too fast in the foot-hooking action, the microprocessor (MCU) 501 will immediately send instructions to the patient's smartphone APP through the wireless communication module 505, and the APP will inform the patient how to adjust the action in the form of voice prompts or animation demonstrations, such as "Please increase the foot-hooking angle by 10 degrees and keep the foot-hooking at a constant speed". At the same time, the microprocessor (MCU) 501 will also dynamically adjust the working parameters of the pressure regulating component 2 and the temperature regulating component 3 according to the patient's movement performance, so as to better adapt to the patient's physical needs in the current training state, such as appropriately increasing the plantar pressure stimulation to enhance the muscle training effect, or fine-tuning the temperature to improve the patient's comfort, thereby optimizing the rehabilitation training experience. This personalized training and real-time feedback mechanism allows patients to understand their performance in a timely manner during each training session and make improvements based on the precise guidance of the equipment, which greatly improves the efficiency of patients in mastering correct rehabilitation techniques, significantly accelerates the rehabilitation process, makes rehabilitation treatment more in line with the individual needs of patients, and improves treatment effects and patient satisfaction.

[0073] Telemedicine and data sharing

[0074] The data storage and transmission module 506 in the control circuit board 5 has a powerful wireless transmission capability and an efficient data storage management function, and successfully realizes seamless data sharing between the foot pump and the telemedicine server or the mobile terminal device of the medical staff. No matter where the medical staff is, as long as they use the authorized mobile terminal or the hospital's telemedicine platform, they can view the patient's training data in real time, including detailed pressure change curves, temperature records, the number of completed movements and quality assessment information, as well as the patient's rehabilitation progress, such as the improvement trend of joint mobility, the degree of muscle strength recovery, etc. This feature greatly facilitates the management and tracking of patients by medical staff, breaks the time and space limitations of traditional rehabilitation treatment, and improves the efficiency and quality of medical services. For example, for patients who continue rehabilitation training at home after being discharged from the hospital, medical staff can timely discover problems in the patient's rehabilitation process based on the remotely acquired data, such as decreased training compliance, abnormal fluctuations in rehabilitation indicators, etc., and give patients timely guidance and intervention through telephone, video calls or remote adjustment of foot pump parameters to ensure the continuity and stability of rehabilitation treatment. At the same time, the device can also receive updated data from the remote server, such as the latest rehabilitation training program, the optimized normal rehabilitation mode database, and the upgrade package of the equipment software system, etc., to ensure that the performance of the foot pump is always at the leading level, and the accuracy and reliability of the data are continuously improved, so as to provide patients with better quality and cutting-edge rehabilitation services, and promote the development of postoperative rehabilitation treatment of joints in a more intelligent and efficient direction.
