Description

Technical Field

[0001] The embodiments of the present application relate to the field of smart medical care, and more specifically, the present invention relates to a method for home monitoring of lymphedema and related equipment. Background Art

[0002] The most common cause of secondary lymphedema is cancer and its treatment. Upper limb lymphedema is often secondary to breast cancer surgery (13.5% to 41.1%), and lower limb lymphedema is often secondary to gynecological tumor surgery (5.00% to 66.67%). Patients will experience limb numbness, appearance changes, fatigue, repeated infections, limb dysfunction, and even mental anxiety and depression, which bring great pain to patients. Because lymphedema is chronic, progressive, and requires lifelong treatment, it is reported that 15% to 54% of breast cancer survivors develop lymphedema within 3 years after surgery. Once the clinical manifestations are obvious, the prognosis of treatment is poor, and there is a tendency to gradually worsen, leading to irreversible fibrotic changes in the tissue. Therefore, it is necessary to monitor such patients and identify the occurrence of lymphedema as early as possible.

[0003] At present, the simple and easy way to monitor lymphedema at home is to use a tape measure to measure the circumference of different parts of the bilateral limbs. This measurement method is convenient, but the accuracy is affected by many factors such as the position and tightness of the tape measure, and the accuracy is poor. For monitoring body fluid composition, human body composition meters are often used in clinical practice, but the instrument is large and expensive, and is often used in medical institutions, which is not convenient for patients to use at home. How to monitor whether patients implement exercise plans on time, whether exercises are in place, and whether limbs have adverse symptoms? There is no convenient way to conduct detailed monitoring, and it is often necessary to follow up through medical institutions or patients actively seek medical treatment and self-report.

[0043] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0044] In order to solve the current common home monitoring methods, such as measuring limb circumference with a tape measure, which is convenient but greatly affected by human factors and difficult to ensure high accuracy. The body fluid composition monitoring instruments used in clinical practice are accurate, but the equipment is expensive and not suitable for patients to use at home, which makes it difficult for patients to conveniently perform long-term and stable self-monitoring at home. Figure 1 , is a schematic flow chart of a method for home monitoring of lymphedema provided in an embodiment of the present application, which may specifically include: steps S110 to S130.

[0045] S110, obtaining circumference data of the patient's affected limb through a monitoring ring, wherein the monitoring ring includes a wristband with an adjustable length, and the wristband can be extended or retracted at an adjustable position.

[0046] It is understood that the core component of the method is a "monitoring ring" which features an adjustable length wristband. The wristband can be extended and retracted to accommodate limb circumferences of different sizes. The monitoring ring can be adjusted according to the size of the limb to measure the circumference of the limb.

[0047] For example, the patient wears the monitoring ring on the affected limb at home every day, selects a fixed position (such as the upper arm or mid-thigh), and adjusts the wristband to the appropriate tightness. Once the wristband is adjusted to the appropriate tightness, the monitoring ring will automatically record the circumference change data of the affected limb. This can be achieved through a simple electronic sensor or a mechanical telescopic system. Thus, in this way, the circumference data of the affected limb can be recorded more accurately, and the operation is simple and fast, suitable for patients to use at home, and avoids the errors caused by inaccurate position or inconsistent tightness in traditional tape measurements.

[0048] For example, a patient who has undergone breast cancer surgery wears a monitoring ring at home every day to measure the circumference of her upper arm. Assume that the circumference data recorded by the patient multiple times within a week are relatively stable, but after the eighth day, the circumference gradually increases. This change may indicate an early sign of lymphedema, and the patient can take timely measures.

[0049] S120, when it is determined that the monitoring ring is retracted to an appropriate length, obtaining the circumference and bioresistivity data of the patient's affected limb at the wearing position of the monitoring ring.

[0050] It is understood that in addition to measuring the circumference, the monitoring ring can also obtain bioresistivity data of the patient's affected limb. Bioresistivity is a technology that analyzes the water content of tissue by measuring its electrical resistance. The more water, the lower the resistance. Lymphedema is swelling caused by the retention of lymph fluid, so changes in the resistivity of the affected limb can reflect the accumulation of fluid in the body.

[0051] Exemplarily, the monitoring ring has built-in electrodes, which, when worn on a limb, can generate a weak current that is conducted through the limb tissue and measures its resistance value. After the monitoring ring is worn on the limb, the system automatically starts the resistivity measurement function and records the bioresistivity data of the affected limb. As a result, the measurement of bioresistivity can provide deeper information, not only limited to changes in the circumference of the limb's appearance, but also reflecting the retention of fluid in the limb. In this way, combined with the circumference data, the condition of lymphedema can be more comprehensively assessed.

[0052] For example, if a patient's circumference does not change much, but the resistivity data shows a gradual decrease in limb resistance, this may indicate that although there is no obvious change in appearance, fluid has begun to accumulate in the body and lymphedema is in the early stages of development. The doctor can recommend preventive treatment for the patient based on this data.

[0053] S130, analyzing the lymphedema condition of the patient's affected limb based on the circumference data and bioresistivity data of the patient's affected limb.

[0054] It can be understood that by collecting circumference data and bioresistivity data, the system can conduct a comprehensive analysis of the lymphedema condition.

[0055] Exemplarily, the system combines the two data, calculates the changes in the water content of the limbs through a built-in algorithm, and determines whether there is lymph retention. Certain thresholds can be preset in the system. For example, when the circumference increases beyond a certain range or the resistivity decreases to a certain value, the system automatically reminds the patient that there may be signs of lymphedema. The system can feed back the results to the patient, reminding them whether further medical intervention is needed, or prompting them whether rehabilitation training is on time and effectively. As a result, this method of data integration and analysis can detect signs of lymphedema early and issue warnings before symptoms are obvious. Patients do not need to wait for obvious swelling to appear, so they can take intervention measures more promptly to delay or avoid worsening of the disease.

[0056] For example, when the system detects that the patient's circumference has not changed significantly but the resistivity continues to decrease, the system will issue an early warning and the patient can go to the hospital for a follow-up visit in time. This will be more effective and the prognosis will be more ideal than waiting until the limbs are severely swollen before treatment.

[0057] In summary, the lymphedema home monitoring method provided in the embodiment of the present application obtains the circumference data of the patient's affected limb through a monitoring ring, and the monitoring ring includes a wristband with an adjustable length, and the wristband can be extended or retracted at the adjustable position; when the monitoring ring is determined to be retracted to an appropriate length, the circumference and bioresistivity data of the patient's affected limb at the wearing position of the monitoring ring are obtained; based on the circumference data and bioresistivity data of the patient's affected limb, the lymphedema condition of the patient's affected limb is analyzed. As a result, the patient does not need to go to the hospital frequently, and can realize self-monitoring of lymphedema by wearing a monitoring ring. This greatly improves the quality of life of patients, especially for patients with chronic diseases. Through the dual data of circumference and bioresistivity, the system can detect early signs of lymphedema earlier and avoid worsening of the disease. Compared with traditional soft tape measurement or monitoring of a single indicator, the dual detection method combining circumference and bioresistivity can significantly improve the accuracy of monitoring and avoid misjudgment or missed diagnosis.

[0058] According to some embodiments, further comprising:

[0059] Sending the measured circumference data and bioresistivity data of the patient's affected limb and / or the lymphedema condition obtained through analysis to a medical terminal associated with the patient;

[0060] Receive a guidance message from the medical terminal to the patient.

[0061] It is understandable that after the patient's affected limb data (circumference data, bioresistivity data, etc.) is acquired by the monitoring ring, the system transmits the data to the medical staff's terminal via wireless communication (such as Wi-Fi, Bluetooth or cellular network).

[0062] Exemplarily, the data processing system in the monitoring ring sends the collected patient's affected limb circumference and bioresistivity data to the medical terminal associated with the patient at a certain time interval (for example, once a day or once a week). The medical terminal can be a doctor's computer, tablet or dedicated health management platform. Medical staff can view the patient's physical data in real time or regularly through the terminal, and judge whether the patient has early symptoms of lymphedema or the risk of recurrence based on the results of data analysis. Thus, through the patient's circumference and bioresistivity data transmitted remotely, medical staff can monitor the patient during home rehabilitation, and once a problem is found, timely feedback can be given to avoid worsening of the patient's symptoms. Through the guidance message of the medical terminal, the patient can get clear treatment advice to ensure that the rehabilitation plan is completed on time and scientifically, and reduce rehabilitation failures caused by personal management errors. Patients do not have to go to the hospital for follow-up visits frequently. Remote monitoring and medical guidance functions reduce the time and economic burden of both doctors and patients, and improve rehabilitation efficiency.

[0063] For example, a patient with lower limb lymphedema received rehabilitation treatment after gynecological tumor surgery. In the second month of rehabilitation, the doctor found that the patient's circumference gradually increased and the resistivity dropped significantly through the monitoring data of the monitoring ring. The doctor sent a message through the system and recommended that the patient go to the hospital for further fluid management treatment. This process ensures early intervention and avoids the deterioration of lymphedema.

[0064] In some examples, the guidance message includes a suggested exercise plan, and the method further includes:

[0065] Monitor the patient's movement intensity through an accelerometer;

[0066] When the exercise intensity is less than the minimum exercise intensity within a preset period, an exercise reminder message is generated;

[0067] Based on daily monitoring data, the changes in lymphedema of the affected limb after the patient completes the recommended exercise plan are analyzed, and the exercise plan is adjusted according to the changes in lymphedema.

[0068] It is understood that the accelerometer can be used to monitor the patient's exercise intensity in real time, so as to determine whether the patient has completed the recommended amount of exercise as planned. These sensors can be embedded in a monitoring ring or worn on the patient's sports equipment (such as a bracelet, shoes, etc.).

[0069] Exemplarily, the acceleration sensor obtains exercise intensity data by measuring the speed and frequency of the patient's limb movements. The sensor can measure the acceleration of the limbs and convert these data into specific exercise intensity values. During the patient's daily activities and exercise, the sensor continuously monitors the exercise intensity and transmits the data to the monitoring system to ensure that the exercise complies with the recommended plan. Therefore, through the monitoring of the acceleration sensor, the system can accurately record the patient's exercise status and determine whether the recommended exercise intensity and duration are reached. This avoids the situation where the patient may affect the recovery of lymphedema due to insufficient or excessive exercise.

[0070] For example, a breast cancer patient who has just undergone surgery needs to do 30 minutes of moderate-intensity arm exercise every day according to the doctor's advice. The accelerometer can monitor whether the patient has completed this amount of exercise. If the patient's exercise intensity is low on that day, the system will identify insufficient exercise.

[0071] It is understandable that if the patient's exercise intensity does not reach the minimum exercise intensity standard within a preset period (such as one day or one week), the system will generate a prompt message to remind the patient to perform rehabilitation exercises in a timely manner.

[0072] Exemplarily, the doctor or system will set a minimum exercise intensity standard based on the patient's physical condition, such as requiring at least 30 minutes of walking or limb training on a certain day. When the system detects that the patient's exercise intensity is lower than the set value, the system will generate an exercise reminder message and send a reminder to the patient through the patient's mobile device or monitoring ring. For example, a message may pop up on the phone to remind the patient to complete the planned exercise. As a result, this function can ensure that patients maintain sufficient exercise in their daily lives. The timeliness of exercise reminders also helps patients maintain good exercise habits.

[0073] For example, a patient was unable to complete his exercise plan due to busy work. The system detected through the acceleration sensor that the patient did not exercise enough throughout the day, and then sent a message to the patient's mobile phone at 5 pm to remind him to do 30 minutes of arm exercises.

[0074] It is understandable that the system not only monitors the patient's movements, but also uses daily data analysis to determine whether there is any change in the lymphedema of the affected limb after the patient completes the exercise plan, thereby evaluating whether the exercise is effective for rehabilitation.

[0075] Exemplarily, after the patient completes the recommended exercise plan, the system will combine the patient's circumference data and bioresistivity data during or after exercise to analyze the effect of exercise on lymphedema. For example, whether the circumference of the affected limb decreases or the resistivity increases after exercise, which means that the fluid drainage effect is better. Based on data analysis, the system can give feedback to inform the patient whether the exercise has produced a positive effect. If the exercise plan does not achieve the expected results, the system will further adjust the recommendations. Therefore, by analyzing the changes in lymphedema after exercise, the system can help doctors or patients better understand the effectiveness of rehabilitation exercises, thereby optimizing personalized treatment plans. Patients can see more clearly the direct effect of exercise on rehabilitation, which increases their motivation to continue exercising.

[0076] For example, a patient completed the 30 minutes of exercise recommended by the doctor on time every day. Through comparative analysis of the data before and after the exercise, the system found that the patient's resistivity increased and the circumference of the affected limb decreased, indicating that exercise helps the discharge of fluid and the rehabilitation effect is good.

[0077] It is understandable that if the system analyzes that the changes in the patient's lymphedema do not match the exercise plan, or the rehabilitation effect is not good, the system will dynamically adjust the patient's exercise plan and provide a new exercise plan.

[0078] For example, based on the patient's rehabilitation progress, the system will recommend adjusting the exercise plan. The adjustments may include increasing the duration of exercise, increasing the intensity of exercise, or changing the type of exercise. The adjustment plan automatically generated by the system can be submitted to the doctor, and the doctor can also make further personalized adjustments to the exercise plan to ensure that it meets the patient's actual situation. As a result, this flexible plan adjustment mechanism makes the rehabilitation process more personalized, and can be dynamically optimized according to the specific situation of each patient, ensuring that the patient's rehabilitation path is more effective and avoiding over-exercise or under-exercise.

[0079] For example, after a patient has exercised for a week, the system finds that although the patient's exercise intensity has reached the standard, the improvement of lymphedema is not significant and the bioresistance has not changed much. The system analysis believes that the patient needs stronger exercise stimulation, so it recommends increasing the daily exercise time to 40 minutes and prompts the doctor to conduct further evaluation.

[0080] In some examples, when determining that the monitoring ring is retracted to an appropriate length, obtaining the circumference and bioresistivity data of the patient's affected limb at the wearing position of the monitoring ring includes:

[0081] When the monitoring ring retraction resistance reaches the preset resistance, determine that the monitoring ring is retracted to an appropriate length;

[0082] When it is determined that the monitoring ring is retracted to an appropriate length, the circumference and bioresistivity data of the patient's affected limb at the wearing position of the monitoring ring are obtained.

[0083] It can be understood that the core of this step is to determine whether the appropriate length is reached by the change in resistance during the retraction of the monitoring ring. The appropriate length means that the monitoring ring is in proper contact with the patient's affected limb, neither too tight to cause discomfort nor too loose to affect the measurement accuracy. During the retraction of the monitoring ring, the system monitors the change in resistance during retraction in real time through the built-in resistance sensor. When the resistance value reaches or exceeds the preset standard value, the system determines that the monitoring ring has been retracted to a tightness suitable for measurement. The preset resistance value is usually set by the doctor or the system according to the condition of the patient's limb. For example, a certain resistance value may indicate that the monitoring ring fits the limb appropriately, does not cause excessive pressure on the patient, and can also ensure the accurate collection of bioresistivity data. Therefore, through real-time monitoring of resistance, the system ensures that the monitoring ring is at an optimal tightness, avoiding errors that may be caused by traditional manual adjustment. This improves the stability and accuracy of the measurement data, especially for bioresistivity, a measurement indicator that is sensitive to contact conditions. Suppose a patient with lower limb lymphedema wears a monitoring ring and the system detects that the resistance is gradually increasing. When the resistance reaches the preset Newton, the system automatically stops retracting, and it is considered that the monitoring ring is at an appropriate tightness and bioresistivity measurement can be performed. The preset resistance setting is intended to ensure that the monitoring ring fits tightly with the affected limb, and the specific value is not limited here.

[0084] It is understandable that when the system determines that the monitoring ring has been retracted to the appropriate length, the next step is to collect bioresistance data of the patient's affected limb. This is an important indicator for evaluating lymphedema, because bioresistance can reflect the accumulation of fluid in the tissue. The electrodes built into the monitoring ring will begin to measure the bioresistance of the affected limb tissue after the ring is fully in contact with the limb. The system can calculate the resistance value through the conduction of microcurrent between tissues. When the electrode is in good contact with the limb, the system measures and records the resistivity data. At this time, the measurement is at the optimal tightness of the monitoring ring, so the resistivity data is more accurate and can better reflect the water content of the limb. Therefore, the design ensures that the tightness of the monitoring ring is moderate when measuring the bioresistance, thereby reducing the error caused by poor contact or over-tightening. Accurate bioresistance data helps to evaluate the fluid accumulation of the patient's affected limb and help medical staff judge the progression of lymphedema. For example, after a patient's monitoring ring is adjusted to the appropriate tightness, the system starts to collect bioresistance data, and the resistance value of the affected limb is measured to be lower than the previous data. This indicates that fluid retention in his limbs is increasing and lymphedema is worsening.

[0085] It is understandable that through this design combining resistance adjustment with bioresistivity measurement, the system achieves more accurate measurement and ensures data acquisition under optimal conditions. This design not only improves the scientific nature of the measurement, but also improves the convenience of home use for patients. By real-time monitoring of the retraction resistance of the monitoring ring, the system can ensure that the contact between the monitoring ring and the patient's limb is in the best state, thereby improving the accuracy of bioresistivity measurement. This method eliminates the need for patients to manually adjust the tightness of the monitoring ring, simplifies the operation steps, and the patient only needs to wear the monitoring ring, and the system will automatically adjust to the appropriate state for measurement. The resistance preset value can be adjusted according to the limb conditions of different patients to ensure that it is suitable for patients of various body shapes and limb conditions, thereby improving the adaptability of the system. For example, a breast cancer patient with upper limb lymphedema after surgery uses a monitoring ring for bioresistivity measurement every day. After the system automatically adjusts to the appropriate tightness, it accurately measures the resistance value of the affected limb and finds that its resistivity gradually increases within a week, showing that fluid retention is reduced and the rehabilitation effect is good. This automated adjustment avoids human errors and improves the patient's home rehabilitation experience.

[0086] In some examples, a section of the monitoring ring is set as a display screen, and the display screen is located on one side of the inner wall of the monitoring ring and has sensors distributed thereon, and when it is determined that the monitoring ring is retracted to an appropriate length, the circumference and bioresistivity data of the patient's affected limb at the wearing position of the monitoring ring are obtained, including:

[0087] When it is detected that all sensors are contacted or covered, determining that the monitoring ring is retracted to a suitable length;

[0088] When it is determined that the monitoring ring is retracted to an appropriate length, the circumference and bioresistivity data of the patient's affected limb at the wearing position of the monitoring ring are obtained.

[0089] It is understandable that the inner wall of the monitoring ring is distributed with sensors, which can monitor in real time whether it is contacted or covered by the surface of the patient's limb. By detecting the signals of these sensors, the system can determine whether the monitoring ring is retracted to a suitable tightness to ensure the accuracy of the bioresistivity measurement. Multiple sensors are arranged on one side of the inner wall of the monitoring ring, and these sensors can sense whether it is in contact with the patient's skin. When the monitoring ring is retracted, the sensors contact the surface of the limb one by one. The system determines whether the current monitoring ring is in close contact with the patient's limb through the feedback signal of the sensor. If all sensors detect that they are covered by the skin, the system believes that the monitoring ring has been retracted to a suitable length, the contact is good, and it is ready for the next measurement. At the same time, the display screen can feedback the status of the sensor to the patient, informing the patient whether the appropriate wearing tightness has been reached. If the sensor is in poor contact, the display screen can remind the patient to adjust the wearing position of the monitoring ring. Therefore, this design ensures that the tightness of the monitoring ring is moderate and improves the accuracy of the measurement through the combined detection of multiple sensors. In particular, the contact situation is judged by the signals of all sensors, avoiding the measurement error caused by local poor contact. In addition, the feedback from the display screen allows patients to understand the wearing situation more intuitively, increasing the convenience of use.

[0090] It is understandable that after the sensor detects that the monitoring ring is in full contact with the limb, the system determines that the monitoring ring is retracted to the appropriate length. At this point, the system can start to obtain the bioresistivity data of the patient's affected limb. Once all sensors detect that they are covered by skin, the system automatically locks the current tightness and stops further retraction. This ensures that the limb is wrapped just right, not too tight or too loose. After determining that the tightness is appropriate, the electrodes built into the monitoring ring begin to measure the bioresistivity data of the affected limb. Through the conduction of weak current between the skin and tissue, the system can obtain accurate resistivity values. The resistivity data is recorded and processed to determine the progression of lymphedema. If the resistivity is low, it means that the fluid content in the tissue is high, which may indicate the aggravation of lymphedema. This method ensures that the contact conditions of the monitoring ring are optimal when the bioresistivity measurement is performed. This reduces the error caused by poor contact and ensures the accuracy of the measurement data. At the same time, the patient only needs to wear the monitoring ring, and there is no need to manually adjust the tightness. The system will automatically detect and control, which greatly improves the ease of use. For example, when a patient with lower limb lymphedema uses a monitoring ring, all sensors detect limb contact, and the system determines that the monitoring ring is in the proper position. The system then automatically measures the bioresistance of the patient's affected limb and finds that the resistivity has decreased, indicating possible fluid retention. The doctor adjusts the patient's rehabilitation plan based on this data.

[0091] It is understandable that, combined with the feedback mechanism of the sensor and the prompt function of the display screen, the system improves the accuracy of bioresistivity measurement by automatically adjusting the tightness of the monitoring ring. The key advantage of this design is that it can judge the wearing condition of the monitoring ring in real time and provide feedback through the display screen to ensure that the wearer can easily understand and operate it. Through the sensor to detect the contact of the limbs in real time, the system can automatically adjust the tightness of the monitoring ring to ensure that it is in the best measurement state and avoid errors that may be caused by manual adjustment. The coverage detection of the sensor ensures that all measurement points are in good contact with the limbs, ensuring the accuracy of the bioresistivity data, thereby improving the early identification and monitoring capabilities of lymphedema. The display screen can intuitively feedback the wearing condition of the monitoring ring, help patients better understand the operation process, improve user experience, and make home rehabilitation monitoring more convenient. For example, when a patient with upper limb lymphedema wore a monitoring ring, the sensor detected that some areas were not in close contact with the limbs, and the display screen prompted the patient to readjust the wearing position. After the patient adjusted according to the prompts, all sensors detected good contact, the system started bioresistivity measurement, and finally generated an accurate rehabilitation report for the patient.

[0092] In some examples, this also includes:

[0093] The patient wears the monitoring ring while holding the smart mobile communication terminal;

[0094] Determine the wearing position data of the monitoring ring on the patient's affected limb based on the distance between the monitoring ring and the worn monitoring ring detected by the intelligent mobile communication terminal;

[0095] Based on the wearing position data, a comparison analysis result of the affected limb is generated when it is detected that the patient monitors the circumference data and bioresistivity data of the affected limb of the patient at the same wearing position again.

[0096] It is understandable that when the patient holds the intelligent mobile communication terminal, the system detects the wearing position of the monitoring ring through the terminal device. This design uses the positioning function of the terminal device (such as Bluetooth, near field communication, or Wi-Fi, etc.) to determine the position of the monitoring ring relative to the terminal, thereby determining the wearing point of the monitoring ring on the affected limb. When the patient holds the intelligent terminal and wears the monitoring ring, the intelligent terminal can detect the distance and position of the monitoring ring through wireless communication technology (such as Bluetooth). Through this distance information, the system can infer the specific wearing position of the monitoring ring on the patient's limb (such as the middle of the upper arm, lower arm, etc.). Based on the distance data obtained by the intelligent terminal, the system will record the wearing position of the current measurement and use it as the reference data for subsequent comparison. At each measurement, the system will automatically check and confirm the wearing position to ensure that each measurement is performed at the same position. Through the positioning of the intelligent mobile communication terminal, the system can accurately calibrate the wearing position of each monitoring ring, avoiding the problem of inconsistent wearing positions when the patient is measured multiple times. This provides a unified benchmark for historical data comparison to ensure the accuracy of measurement and the consistency of data. Suppose a patient who has undergone breast cancer surgery measures the circumference and bioresistivity of the upper arm through a monitoring ring every day. The system detected the location of the monitoring ring in the middle of her upper arm through the smartphone in her hand. The next time she measures, the system will remind the patient to make sure the monitoring ring is worn in the same position to ensure comparability of the data before and after.

[0097] Exemplarily, when the system detects that the patient is measured again at the same wearing position within a predetermined time (for example, within a week or a month), the system can generate a horizontal comparison result of the historical data based on the same position data. At the same time, the system can also compare the data of the contralateral limb (i.e., the healthy limb) at the same position for bilateral comparative analysis. After recording the wearing position data of the patient for multiple measurements, the system can compare the multiple measurement results at the same position. For example, the system compares the circumference and bioresistivity data during the two measurements to determine the change trend of the patient's limbs. The system can also record the bilateral limb data at the same position at the same time, and further analyze the degree of lymphedema by comparing the data of the affected limb and the healthy limb. If the bilateral difference is obvious, it indicates that the affected limb has edema. When it is detected that the patient is measured again within the predetermined time, the system will automatically generate a comparison report, including a trend chart of the change of historical data and a difference analysis between the affected limb and the contralateral limb. Through this comparison mechanism, the system can not only help patients track their own rehabilitation progress, but also detect abnormal changes in the affected limb as early as possible by comparing with the healthy limb, and provide more accurate rehabilitation monitoring. This not only ensures the horizontal comparability of the data, but also can effectively detect the dynamic changes of the disease. For example, after a patient with lower limb lymphedema underwent multiple measurements, the system recorded that she wore the monitoring ring in the middle of the thigh. The system compared her data over the past month and found that the circumference gradually increased, while the bioresistance decreased, indicating that the lymphedema worsened. At the same time, the system also compared the circumference of the affected limb with the circumference of the affected limb measured historically, and found that the circumference of the affected limb was significantly larger than the circumference of the affected limb previously recorded, further indicating that the condition has worsened.

[0098] It is understandable that through the linkage between the smart terminal and the monitoring ring, the system can ensure that the wearing position is consistent each time during measurement, avoiding measurement errors caused by inconsistent positions. At the same time, combined with historical data and data comparison of the contralateral limbs, the system can provide patients with more comprehensive and accurate rehabilitation monitoring and disease assessment. Through the distance positioning of the smart terminal and the monitoring ring, the system ensures that each measurement is performed at the same position, avoiding errors caused by multiple measurement data due to different positions. The system generates historical comparison results based on multiple measurement data at the same position, so that patients can clearly understand the dynamic changes in their own rehabilitation process. Through comparative analysis of bilateral limbs, the system can detect abnormalities early and provide patients with a comprehensive evaluation of bilateral data to help early intervention and treatment. For example, after a patient with upper limb lymphedema received rehabilitation training, the system automatically recorded her multiple measurement data. Through historical comparison analysis, the system found that the circumference data of her affected limb gradually decreased and the resistivity increased, indicating that the rehabilitation effect was good. At the same time, the system also generated a comparative analysis of the healthy limbs, showing that the difference between the two limbs was decreasing, further proving the effect of rehabilitation training.

[0099] In some examples, this also includes:

[0100] The patient wears the monitoring ring while holding the smart mobile communication terminal;

[0101] Determine the wearing position data of the monitoring ring on the patient's affected limb based on the distance between the monitoring ring and the worn monitoring ring detected by the intelligent mobile communication terminal;

[0102] Based on the wearing position data, when it is detected that the patient monitors the circumference data and bioresistivity data of the affected limb at the same wearing position again within a predetermined time, a comparison analysis result between the affected limb and the healthy limb is generated.

[0103] Exemplarily, by shortening the preset time setting, the system can identify that the patient has monitored the left and right limbs separately in a short period of time. If the system detects that the patient wears the monitoring ring in a short period of time and measures the left and right limbs respectively, the system will automatically determine that the measurement is a bilateral comparison monitoring. The system sets a shorter time window (for example, a few minutes or less) to identify whether the patient has measured both limbs in a short period of time. The system records the changes in the wearing position of each monitoring ring through the distance sensing or other positioning technology of the smart mobile terminal. If within the preset time window, the system detects that the monitoring ring is measured on the left and right limbs successively, the system will automatically identify this monitoring as a bilateral comparison measurement, rather than two unilateral independent measurements. By shortening the preset time, the system can quickly identify that the patient is measuring both limbs in the same monitoring, thereby focusing the comparison analysis on the comparison of bilateral data. This mechanism can ensure that the measurement data of both limbs are carried out under the same time conditions, reducing the impact of physiological changes caused by too long time intervals on data comparison. Suppose a patient with lymphedema wears a monitoring ring in a short period of time to measure the circumference and bioresistivity of the left and right limbs in the same monitoring. The system detects that the time between the two measurements is very close and determines that this is a two-sided comparison measurement, and then generates a two-sided comparison analysis result.

[0104] See also Figure 2 , an embodiment of the lymphedema home monitoring device in the embodiment of the present application may include:

[0105] A monitoring unit 21, used to obtain the circumference data of the patient's affected limb through a monitoring ring, wherein the monitoring ring includes a wristband with adjustable length, and the wristband can be extended or retracted at an adjustable position;

[0106] An acquisition unit 22 is used to acquire the circumference and bioresistivity data of the affected limb of the patient at the wearing position of the monitoring ring when determining that the monitoring ring is retracted to an appropriate length;

[0107] The analyzing unit 23 is used to analyze the lymphedema condition of the patient's affected limb based on the circumference data and bioresistivity data of the patient's affected limb.

[0108] In summary, the lymphedema home monitoring device provided in the embodiment of the present application obtains the circumference data of the patient's affected limb through a monitoring ring, and the monitoring ring includes a wristband with an adjustable length, and the wristband can be extended or retracted at the adjustable position; when the monitoring ring is determined to be retracted to an appropriate length, the circumference and bioresistivity data of the patient's affected limb at the wearing position of the monitoring ring are obtained; based on the circumference data and bioresistivity data of the patient's affected limb, the lymphedema condition of the patient's affected limb is analyzed. As a result, the patient does not need to go to the hospital frequently, and can realize self-monitoring of lymphedema by wearing a monitoring ring. This greatly improves the quality of life of patients, especially for patients with chronic diseases. Through the dual data of circumference and bioresistivity, the system can detect early signs of lymphedema earlier and avoid worsening of the disease. Compared with traditional soft tape measurement or monitoring of a single indicator, the dual detection method combining circumference and bioresistivity can significantly improve the accuracy of monitoring and avoid misjudgment or missed diagnosis.
