Description

Technical Field

[0001] This invention relates to a medical monitoring device, specifically a wearable device for dynamic detection of lower limb edema. Background Technology

[0002] Lower extremity edema is a common sign of various clinical diseases, such as heart failure, chronic kidney disease, cirrhosis, deep vein thrombosis of the lower extremities, and lymphedema. Edema fluid tends to accumulate in areas with looser interstitial spaces and greater influence from gravity; therefore, the thighs, calves, ankles, and around the knees are the main areas prone to lower extremity edema. Medical assessment of the severity of edema in these areas can effectively reflect the patient's pathological state and disease progression, providing important information for guiding clinical treatment and predicting prognosis. Therefore, accurate and timely assessment of lower extremity edema is crucial for implementing effective medical interventions.

[0003] Currently, the most common clinical method for assessing lower extremity edema is to use a leg circumference measuring tape to intermittently measure multiple fixed locations on both lower limbs (such as the ankle, the thickest part of the calf, the knee joint, and the thigh). The occurrence and resolution of edema are determined by recording and comparing changes in leg circumference at different time points. This method is intuitive and low-cost, and is widely used in short-term inpatient or outpatient assessments. However, the aforementioned traditional measurement method still has some insurmountable drawbacks in practical application.

[0004] First, leg circumference measurement is a cumbersome procedure that relies entirely on manual intervention. Each measurement requires the patient or medical staff to manually locate the measurement point, wrap the measuring tape around the leg, and read the data, a time-consuming and laborious process. Second, data loss and forgetting are prone to occur, especially when patients are not under the supervision of a medical institution (such as during home rehabilitation or daily outings). Patients may find it difficult to strictly follow medical advice to measure their leg circumference on time and frequently, resulting in some edema events not being recorded or key changes in the early stages of edema not being detected in time, thus delaying intervention. Third, there is a lack of continuous and dynamic monitoring capabilities. The degree of edema in patients at different stages of the disease may fluctuate or gradually change, while intermittent measurements can only obtain data fragments at discrete points in time, making it easy to miss key edema changes and failing to reflect the complete trend and real-time status of edema development. This limits medical staff's systematic evaluation of the patient's condition evolution and treatment effectiveness, and is also not conducive to the development of personalized rehabilitation plans.

[0005] In summary, existing methods for assessing lower limb edema based on leg circumference measuring scales have significant shortcomings in terms of convenience, patient compliance, and real-time monitoring. Therefore, designing a technical solution suitable for daily patient wear and capable of real-time dynamic monitoring of lower limb edema has become an urgent technical problem to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to address the problems existing in the above-mentioned background technology by proposing a daily wearable dynamic detection device for lower limb edema. This device can be worn on the lower limbs daily and achieves real-time dynamic monitoring of lower limb edema by positioning and wrapping around the knee and multiple monitoring components that are positioned and wrapped around target parts of the lower limbs (thigh, calf, ankle, etc.).

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A daily wearable device for dynamic detection of lower limb edema includes a monitoring and reminder component, a knee-mounted component, and at least two limb-mounted components worn on the thigh and / or calf. The knee-wearing component includes a knee wrap, a knee monitoring airbag, and a base monitor. The knee monitoring airbag is configured as a ring-shaped airbag located inside the knee wrap and adapted to the circumference of the patella. The base monitor is located outside the knee wrap and includes a controller module, a miniature air pump a, a pressure sensor a, and a battery. The miniature air pump a is connected to the knee monitoring airbag through an air delivery channel, and the sensing end of the pressure sensor a is placed inside the knee monitoring airbag. The limb wearing component includes a ring-shaped wrapping strap, a positioning monitoring airbag, and a branch monitor. The ring-shaped wrapping strap is adjustable in tightness to fit different leg sizes. The positioning monitoring airbag is configured as a flat airbag located inside the ring-shaped wrapping strap and arranged along the length of the ring-shaped wrapping strap. The branch monitor is located outside the ring-shaped wrapping strap and is equipped with a miniature air pump b and an air pressure sensor b. The miniature air pump b is connected to the positioning monitoring airbag through an air delivery passage, and the sensing end of the air pressure sensor b is placed inside the positioning monitoring airbag. Each limb wearable component's branch monitor is connected to the base monitor via an external signal line. The miniature air pump a, air pressure sensor a, miniature air pump b, and air pressure sensor b are all connected to the controller module via circuitry. The monitoring and reminder component includes an independent wearable piece for wearing on easily observable parts of the body. The independent wearable piece is equipped with a reminder. The controller module is equipped with a wireless communication module, and the reminder establishes a signal connection with the base monitor through the wireless communication module.

[0008] Compared with existing technologies, the wearable lower limb edema dynamic detection device that adopts the above-mentioned technical solution has the following beneficial effects: By combining multiple limb-mounted components (covering the thigh, calf, etc.) with a knee-mounted component, it can be directly worn on the lower limbs. Patients can wear it for extended periods during daily activities, enabling real-time, continuous monitoring of multiple edema-prone areas in the lower limbs. Automatic inflation and pressure detection replace manual measurement, reducing the need for frequent manual operation by patients and healthcare workers, lowering dependence on manual operation and the risk of forgetfulness. It also overcomes the shortcomings of traditional intermittent measurements, allowing for real-time monitoring of current edema levels and continuous changes and trends, providing more comprehensive data support and guidance for assessing disease progression and developing treatment strategies. Employing a distributed structure of "base monitor + multiple branch monitors," each limb-mounted component is connected to the base monitor via an external signal line. This allows for flexible addition or removal of monitoring sites as needed (e.g., monitoring only the calf, or simultaneously monitoring the thigh, calf, and ankle), while also facilitating the inspection, replacement, or cleaning of individual components.

[0009] By using a ring-shaped airbag (knee) and a flat airbag (thigh, calf, or ankle) to fit specific anatomical locations, combined with a pressure sensor, the changes in tissue circumference can be accurately and quantitatively detected. This eliminates the instability caused by positioning deviations, reading errors, or differences in techniques between different operators during manual measurement, and significantly improves the accuracy and repeatability of edema assessment.

[0010] The monitoring and alerting component can visualize the current degree of edema in various parts of the body through an alert device on an independent wearable device. When the degree of lower limb edema reaches a preset threshold or the rate of change is abnormal, it can receive feedback signals from the monitor via wireless communication and actively send alert signals to inform the patient or medical staff in a timely manner, which is conducive to taking intervention measures as early as possible.

[0011] Within the scope of practical application and reasonable functional upgrades, the wireless communication module configured in the controller module can transmit real-time collected air pressure data (reflecting changes in leg circumference) to mobile phones, nursing terminals, or cloud platforms, enabling remote viewing, storage, and analysis of the data; at the same time, the monitoring and reminder component can be worn independently on an easily observable part (such as the wrist), allowing patients to be informed of their status in a timely manner, and medical staff can also be informed of abnormal situations remotely, improving the efficiency of medical collaboration.

[0012] Preferably, the knee wrap includes a front knee surround, an upper knee strap, and a lower knee strap. The annular airbag and the base monitor are both located on the front knee surround. The upper knee strap and the lower knee strap each include connecting straps a extending from the front knee surround to both sides. The two opposite connecting straps a form an annular wrap structure that tightens and wraps the leg. The annular wrap includes a base strap and connecting straps b extending from the base strap to both sides. The two connecting straps b form an annular wrap structure that tightens and wraps the leg. The positioning and monitoring airbag extends from the base strap to the connecting strap b, and the branch monitor is located on the base strap.

[0013] Preferably, the base monitor includes a base housing a and a cover a. The base housing a is fixedly mounted on the knee wrapping strap. The controller module, the micro air pump a, the air pressure sensor a, and the battery are integrated in the base housing a. The cover a is provided with an interactive control component, which is electrically connected to the controller module. The branch monitor includes a base housing b and a cover b. The base housing b is fixedly mounted on the ring wrapping strap. The micro air pump b and the air pressure sensor b are integrated in the base housing b.

[0014] Preferably, each branch monitor is fixedly connected to an external signal line, which has a flexible and skin-friendly coating. One end of the external signal line is connected to the circuit of the miniature air pump b and the air pressure sensor b, and the other end is provided with a docking end. Both the base monitor and the branch monitor are provided with docking ports, which are connected to the controller module circuit. The docking end and the docking port are detachably connected to realize the series connection of the knee wearing component and multiple limb wearing components.

[0015] The basal monitor and branch monitors, as well as the individual branch monitors, are connected via a detachable series circuit, enhancing the device's flexibility and ease of use. The skin-friendly, flexible external signal cable reduces the feeling of foreign objects during wear, improving patient comfort and compliance during long-term use. The external signal cable connection scheme allows for quick assembly and disassembly of the knee-mounted component and multiple limb-mounted components, facilitating adjustments to the monitoring location according to actual needs and simplifying the device's donning, doffing, storage, and cleaning maintenance.

[0016] Preferably, both the base monitor and the branch monitor are equipped with a temperature sensor for monitoring skin surface temperature. The sensing end of the temperature sensor of the base monitor is located on the inner wall of the knee wrapping band, and the sensing end of the temperature sensor of the branch monitor is located on the inner wall of the ring wrapping band.

[0017] Preferably, both the base monitor and the branch monitor are equipped with temperature sensors for monitoring skin surface temperature; In the base monitor, the temperature sensor is installed in the base housing a, and the sensing end of the temperature sensor is located on the inner wall of the knee wrapping band.

The interactive control includes a function button a for controlling the edema monitoring mode and a function button b for controlling the temperature monitoring mode. Function buttons a and b are respectively equipped with indicator lights.

[0018] By integrating temperature sensors into the inner wall of the wearable components in the knee and limbs, skin surface temperature can be collected simultaneously while monitoring edema, enabling dynamic multi-parameter assessment and helping to differentiate between different pathological types such as inflammatory, venous, or lymphoid edema. Interactive control buttons and indicator lights allow for separate activation and deactivation of edema and temperature monitoring modes, providing intuitive operation and visual status updates to meet individualized monitoring needs.

An anti-slip skin-friendly layer is attached to the inner side of the elastic tightening parts. The anti-slip skin-friendly layer is configured as self-adhesive silicone or silicone pressure-sensitive adhesive.

[0021] By incorporating elastic constriction sections on both sides of the positioning and monitoring airbag, the fit and constriction stability of the ring-shaped wrapping strap are improved for different leg shapes, preventing slippage during wear, ensuring accurate airbag positioning, and guaranteeing a better fit between the airbag and the skin. An anti-slip, skin-friendly layer on the inner side enhances the anti-slip effect while reducing friction and irritation to the skin, improving comfort during long-term wear.

The information displayed on the prompt panel includes: a numbered area corresponding to the number of the knee-wearing component and each limb-wearing component, and displays the degree of edema monitored by the knee-wearing component or limb-wearing component corresponding to this numbered area.

[0024] The easily removable silicone wristband-style individual wearable device enhances patient convenience and compliance in daily use. The information panel can number and differentiate the knee and other limb wearable components, displaying numerical or visual information on the degree of edema. This allows patients and healthcare professionals to easily identify the edema status of different monitoring sites, facilitating rapid location of abnormal areas and improving the readability of monitoring data and the efficiency of clinical decision-making.
