Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rehabilitation medicine, in particular to a self-rehabilitation body position method for preventing and relieving lower limb venous congestion. BACKGROUND

[0002] Lower limb venous congestion is a common pathophysiological state in clinical practice, especially in professional groups who need to maintain standing or sitting posture for a long time, pregnant women, and individuals with reduced function of the venous system. The root cause is that the continuous effect of gravity increases the resistance of blood and interstitial fluid in the lower limbs to the heart, and the intravenous pressure continues to rise, thereby causing a series of discomfort symptoms such as leg swelling, acid swelling, fatigue, and so on. Long-term existence is also an important inducement for varicose veins, skin nutrition disorders, and even deep venous thrombosis.

[0003] In the field of non-medical daily health management, it is a generally recognized concept to improve lower limb circulation by changing body position. Existing technical information, such as extensive health popularization, usually gives principle suggestions such as "try to elevate the legs when resting" or "elevate the feet". However, these common-sense, fragmented information has significant limitations: first, its content often stays at the general concept level, lacking a set of clear, standardized, and standardizable implementation step guidelines, such as how to start, how to specifically place the limbs, what kind of accurate mechanical state should be achieved, and how long the reasonable time should be maintained. The ambiguity in operation leads to unstable implementation results, making it difficult to achieve predictable and repetitive physiological improvement. Second, existing common sense defaults and almost exclusively points to the elevation of both legs in the supine position, ignoring the actual needs brought by different use scenarios (such as habitual side-lying sleep at night) and individual physical condition differences (such as waist discomfort limiting long-term supine position), resulting in insufficient applicability and compliance of the method for some groups. Third, existing suggestions usually regard body position management as a completely static passive intervention, failing to organically combine with physiological mechanisms that can actively enhance venous return power (such as muscle pump action), thereby limiting the maximization of its circulation promotion efficiency. In addition, existing common sense generally lacks pre-existing safety prompts for specific health conditions of users, failing to incorporate individual risk assessment into the necessary steps of method implementation. SUMMARY

[0004] Therefore, the embodiment of the present application provides a self-rehabilitation body position method for preventing and relieving lower limb venous congestion to solve or improve the technical problems in the prior art.

[0005] The technical solution of the embodiment of the present application is as follows: a self-rehabilitation body position method for preventing and relieving lower limb venous congestion, comprising the following steps: S1, preparation step: the user lies in a supine position on a support plane; S2, a body position adjusting step: the user supports both lower limbs with the help of a lower limb support body, so that both lower limbs are lifted from the ankle joint to the hip joint region and maintained at a position higher than the user's heart level, forming a stable supine lower limb lifting body position, to guide the venous blood and lymph of the lower limbs to flow back to the heart by gravity; S3, a maintaining step: maintaining the supine lower limb lifting body position for a predetermined duration, to achieve sustained decompression of the lower limb venous system and promote fluid circulation.

[0006] Among them, the lower limb support body is configured to provide stable support in a non-hollow structure or a hollow structure with ventilation and heat dissipation function.

[0007] As an improvement, the method further includes an alternative body position step suitable for a lateral position: when the user chooses a lateral position, the upper single lower limb is placed on a lower limb support body, so that the side lower limb is lifted from the ankle joint to the hip joint region and maintained at a position higher than the heart level, forming a lateral single limb lifting body position.

[0008] As an improvement, in the lateral single limb lifting body position, the other side lower limb on the lower side can be naturally flexed to maintain the balance and stability of the body in the lateral position.

[0009] As an improvement, in the S2 step, the lifting position is such that the longitudinal axis of the lower limbs forms an angle with the horizontal plane between 45 degrees and 90 degrees.

[0010] As an improvement, the predetermined duration in the S3 step is greater than 15 minutes.

[0011] As an improvement, when the maintaining step is performed, the user simultaneously performs active ankle pump exercise, which includes alternating flexion and extension and circumferential movement of the ankle joint, to further enhance the pumping effect of venous return through rhythmic contraction and relaxation of calf muscles.

[0012] As an improvement, before performing the S1 step, a step S0 is further included: a health status evaluation step, specifically, if the user is known to have severe heart failure, uncontrolled hypertension or glaucoma, the user needs to consult a doctor before implementing the method.

[0013] Compared with the prior art, the beneficial effects of the present application are: by providing systematic and standardized operation steps, the specific process from preparation, body position adjustment to maintenance is clarified, the problems of unclear operation guidance and unstable effect in the prior art are overcome, and standardized intervention for lower limb venous congestion prevention and relief is realized. Secondly, on the basis of the standard supine lifting position, the alternative implementation mode of lateral single limb lifting is introduced, which effectively solves the problems of insufficient applicability and poor compliance caused by single posture in the existing method. In addition, by combining static body position lifting with active ankle pump movement, the synergistic effect of muscle pump effect and gravity guidance is utilized to significantly enhance the kinetic efficiency of venous and lymphatic return, making up for the functional limitations of the prior art which only relies on passive position. At the same time, the pre-step of health status assessment is added, which provides safety warning and physician consultation for specific groups such as heart failure, uncontrolled hypertension and glaucoma, etc., improving the overall safety and risk control ability of the method, and realizing the technical effect of effective self-rehabilitation under the premise of ensuring user safety.

[0020] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0021] The present application proposes an autonomous rehabilitation body position method for preventing and relieving lower limb venous congestion, comprising the following steps: S1, preparation step: the user lies flat in a supine position on a support plane; S2, body position adjusting step: the user supports the lower limbs by means of a lower limb support body, so that the lower limbs are lifted as a whole from the ankle joint to the hip joint region and maintained at a position higher than the user's heart level, forming a stable supine lower limb lifting body position, so as to guide the heart return of lower limb venous blood and lymph by gravity; S3, maintaining step: maintaining the supine lower limb lifting body position for a predetermined duration to achieve continuous decompression of the lower limb venous system and promote fluid circulation.

[0022] Among them, the lower limb support body is configured to provide a stable support non-hollow structure or a hollow structure with ventilation and heat dissipation function.

[0023] It is noted that the autonomous rehabilitation body position method refers to a self-management approach in which the user adjusts the body posture without direct intervention from professional medical personnel, through self-operation or auxiliary tools, to prevent or alleviate specific physiological discomfort. This method emphasizes the active participation and self-execution of the user. The support plane refers to the horizontal or approximately horizontal surface that the user's body contacts when adjusting the body position, such as a bed surface, yoga mat, or ground. This plane provides the user with basic support. The lower limb support body refers to an auxiliary device used to support the user's both lower limbs or a single lower limb. This support body is designed to provide stable support to ensure that the lower limbs maintain a fixed posture during lifting. Its structure can be a solid-filled non-hollow structure to provide uniform support force, or a hollow structure with holes or grids to promote air circulation and reduce local heat accumulation. The supine lower limb lifting body position refers to a specific body posture formed when the user is in a supine position, with both lower limbs from the ankle joint to the hip joint region being lifted as a whole and maintained at a position higher than the heart level. This body position aims to utilize the effect of gravity to promote the heart-directed return flow of venous blood and lymph in the lower limbs. The preset duration refers to the length of time the user maintains the specific body position after adjusting the body position. This time length can be set according to individual needs, rehabilitation goals, or professional recommendations to ensure that the body position intervention achieves the expected physiological effect.

[0024] The method provided by the embodiment includes the following steps in the specific implementation process: First, a preliminary step S1 is performed. In this step, the user is guided to lie in a supine position on a support plane. The support plane can be a bed, sofa, yoga mat, or ground, etc., and its selection depends on the user's personal preference and environmental conditions. The user should ensure that the body trunk and head are stably supported to provide a stable foundation for subsequent lower limb lifting operations.

[0025] Secondly, a body position adjustment step S2 is performed. In this step, the user supports both lower limbs with a lower limb support body. The lower limb support body can be a specially designed leg lifting pad, a stack of pillows, a folded blanket, or any object that can provide stable support. Through the support body, both lower limbs from the ankle joint to the hip joint region are lifted as a whole. The lifting height is adjusted to maintain both lower limbs at a position higher than the user's heart level. This lifting operation is used to utilize the effect of gravity to promote the heart-directed return flow of venous blood and lymph in the lower limbs, thereby reducing the pressure on the lower limb venous system. Thus, a stable supine lower limb lifting body position is formed.

[0026] Further, the lower limb support body is configured to provide a stable support structure. As an implementation, the support body adopts a non-hollow structure, such as a solid pad made of high-density foam, memory foam, or inflatable material. Such a structure can provide uniform and firm support, ensuring that the lower limbs are not easily displaced during lifting. As another implementation, the support body adopts a hollow structure with ventilation and heat dissipation functions, such as a grid material, a structure with ventilation holes, or a frame structure. Such a structure, while providing the necessary support, helps to circulate air, reducing the stuffy feeling in the contact area between the lower limbs and the support body, and improving the comfort of use.

[0027] Finally, a maintenance step S3 is performed. In this step, the user maintains the supine lower limb lifting body position described above for a predetermined duration. This duration can be set according to the individual's tolerance and rehabilitation needs, for example, it can be several minutes to several tens of minutes. By maintaining this position, the lower limb venous system can be continuously decompressed, and the body fluid circulation is continuously promoted, thereby achieving the purpose of preventing and relieving lower limb venous congestion.

[0028] The method provided by the embodiment forms a systematic and standardized self-rehabilitation process through explicit preparation, body position adjustment and maintenance steps. The method uses the lower limb support body to lift both lower limbs above the heart level, effectively uses gravity to promote the venous blood and lymph of the lower limbs to flow back to the heart, thereby achieving continuous decompression of the lower limb venous system and promoting body fluid circulation. This scheme overcomes the limitations of non-standard operation and uncertain effect in the prior art, and provides a standardized technical solution with strong operability and clear effect for preventing and relieving lower limb venous congestion.

[0029] In some embodiments of the above-mentioned application, a method for lifting both lower limbs in a supine position to promote venous return is proposed. However, in actual application, some users may have difficulty maintaining a supine position due to personal habits, physical conditions, or discomfort from maintaining a single position for a long time, thereby limiting the applicability and compliance of the rehabilitation body position method.

[0030] To this end, the application further provides a self-rehabilitation body position method for preventing and relieving lower limb venous congestion, which further includes an alternative body position step suitable for a lateral position: when the user chooses a lateral position, the upper single lower limb is placed on a lower limb support body, so that the side lower limb from the ankle joint to the hip joint region is lifted and maintained at a position higher than the heart level, forming a lateral single limb lifting position.

[0031] The alternative body position step for side-lying position is used to provide an additional rehabilitation body position option for the user other than supine position. Considering that some users might prefer side-lying due to physiological habit, comfort requirement, or specific health condition, this alternative body position step greatly expands the applicability of the method to a wider range of users and scenarios. When the user chooses side-lying position, the upper single lower limb is placed on a lower limb support. In side-lying position, the user typically has one side of the body in contact with the support plane and the other side of the body facing upwards. The present solution explicitly instructs to elevate the "upper single lower limb". This is because the lower limb on the lower side is usually compressed by the body and its elevation operation is relatively complex, while the upper lower limb is more convenient to elevate and can effectively utilize gravity. The lower limb support can be the same or similar structure as the support used in supine position, for example, a wedge-shaped pillow, a specially designed leg support cushion, or a stack of ordinary pillows that can provide stable support. The side lower limb is elevated from the ankle joint to the hip joint region and maintained at a position higher than the heart level, ensuring that the elevated single lower limb in side-lying position also achieves the same venous return effect as in supine position. By elevating the entire lower limb (from the ankle joint to the hip joint) above the heart level, gravity can be effectively utilized to promote the return of venous blood and lymph to the heart, reducing the pressure on the lower limbs. The height of the elevation should be sufficient to raise the lowest point of the lower limb (usually the ankle joint) above the heart level to ensure the effectiveness of gravity. The final side-lying single-limb elevation position is formed, which is the final state of this alternative step, which maintains the comfort of the user in side-lying position while effectively elevating the single lower limb, thereby achieving the purpose of preventing and relieving venous congestion.

[0032] By introducing the alternative body position step for side-lying position, the present method effectively solves the discomfort or compliance problems of some users who have been in supine position for a long time. When the user chooses side-lying position, by placing the upper single lower limb on the lower limb support and elevating it to a position higher than the heart level, the gravity can continue to be utilized to promote the return of venous blood and lymph to the heart of the side lower limb, thereby significantly improving the comfort and applicability of the rehabilitation body position method without sacrificing the rehabilitation effect. This flexibility allows the user to choose the most comfortable body position according to their own habits and needs, thereby improving the compliance of the rehabilitation program and ensuring the continuity and effectiveness of preventing and relieving venous congestion in the lower limbs.

[0033] In some embodiments of the present application, an alternative body position procedure is proposed for the side-lying position, i.e. when the user chooses the side-lying position, the lower limb on the upper side is placed on a lower limb support, so that the lower limb on the upper side is lifted from the ankle joint to the hip joint area and maintained at a position higher than the heart level, forming a side-lying single-limb lifting body position. However, in actual operation, lifting only one lower limb may cause the body to be difficult to maintain stable balance in the side-lying position, thereby affecting the comfort and continuity of the rehabilitation body position.

[0034] To this end, the present application further proposes that in the above-mentioned side-lying single-limb lifting body position, the lower limb on the lower side can be naturally flexed to maintain the balance and stability of the body in the side-lying position.

[0035] Specifically, when the user is in the side-lying single-limb lifting body position, the lower limb on the lower side of the body, i.e. the lower limb that is not lifted, is not forcibly straightened or fixed, but is allowed to naturally bend according to the user's comfort. This natural flexion can refer to the bending of the knee joint and / or the hip joint, which can be achieved by the user's autonomous adjustment or by placing soft pads, pillows or other aids under the knee or hip of the lower limb on the lower side, so that the flexion posture is naturally formed in a relaxed state. By allowing the lower limb on the lower side to naturally flex, the contact area of the body with the support plane (such as the bed surface) can be increased, and the distribution of the body's center of gravity can be adjusted, thereby providing a more stable support point. This posture helps to prevent the body from tilting forward or backward when lying on the side, reduces muscle tension, improves the comfort and safety of the body position, and enables the user to maintain the rehabilitation body position for a longer period of time.

[0036] By the above technical solution, the method effectively solves the problem of insufficient body balance that may occur in the side-lying single-limb lifting body position. When one lower limb is lifted, the natural flexion of the other lower limb can increase the contact area of the body with the support surface and optimize the distribution of the body's center of gravity, thereby providing a more stable support. This not only significantly improves the stability and comfort of the user in the side-lying position, reduces muscle tension or discomfort caused by unstable posture, but also enables the user to maintain the rehabilitation body position for a longer period of time, thereby ensuring the continuity and effectiveness of the prevention and relief of venous stasis.

[0037] In some embodiments of the present application, a method is proposed for promoting venous return by lifting the lower limbs to utilize gravity. However, in actual operation, if the lifting angle is not appropriate, the gravity guiding effect may not be good, and the venous stasis cannot be fully relieved, or the lifting angle may be too high, which may increase the discomfort of the user, and even affect the smoothness of blood circulation, thereby limiting the application effect of the method.

[0038] To this end, the present application further proposes that in the S2 step, the position of the lifting is such that the angle between the longitudinal axis of the lower limbs and the horizontal plane is between 45 degrees and 90 degrees. Specifically, the angle between the longitudinal axis of the lower limbs and the horizontal plane refers to the angle between the line connecting the ankle joint to the hip joint of the user (representing the overall longitudinal axis of the lower limbs) and the support plane in which the user lies in the supine position (representing the horizontal plane). This angle is a key parameter for measuring the lifting height of the lower limbs, and directly affects the driving force of gravity on the venous blood return. Limiting the angle to between 45 degrees and 90 degrees serves to ensure that the lifting of the lower limbs can effectively utilize gravity to promote the centripetal return of venous and lymphatic fluids, while avoiding the problem of insufficient effect due to too low lifting angle, or discomfort or excessive pressure on the joints due to too high lifting angle. For example, when the angle is close to 90 degrees, the lower limbs are almost perpendicular to the horizontal plane, and the gravity effect is the largest, but it may cause a greater burden on the knee and hip joints, and long-term maintenance may be uncomfortable; when the angle is close to 45 degrees, the gravity effect is moderate, the comfort is higher, and the return can still be effectively promoted. The angle can be achieved by adjusting the height, shape or inclination of the lower limb support body, for example, using wedge-shaped pads, height-adjustable supports or inflatable supports.

[0039] By precisely limiting the angle between the longitudinal axis of the lower limbs and the horizontal plane to between 45 degrees and 90 degrees, the present method can provide an optimized gravity gradient to ensure that the venous blood and lymphatic fluid of the lower limbs can be efficiently and continuously returned to the heart, thereby significantly enhancing the decompression effect of the venous system. This specific angle range ensures effective promotion of fluid circulation while taking into account the comfort and safety of the user, avoiding the problem of insufficient effect due to insufficient lifting or discomfort due to excessive lifting. Therefore, this solution not only improves the effectiveness of the rehabilitation position method, but also improves the user's compliance, allowing them to maintain the position for a longer period of time, thereby achieving more persistent and significant prevention and relief of lower limb venous congestion.

[0040] In some embodiments of the present application described above, the venous return and lymphatic circulation of the lower limbs are promoted by maintaining the supine lower limb lifting position for a predetermined duration. However, if the predetermined duration is set too short, it may result in insufficient decompression of the venous system of the lower limbs, and the improvement of fluid circulation is not obvious, thereby affecting the persistence and effectiveness of the rehabilitation effect.

[0041] To this end, the present application further proposes that the predetermined duration in the S3 step is greater than 15 minutes.

[0042] The preset duration in the S3 step is greater than 15 minutes, which is used to ensure that the user needs to maintain the body position for at least 15 minutes after completing the lower limb lifting position adjustment. This time setting is used to ensure that the venous blood and lymph fluid in the lower limbs has enough time to fully return to the heart under the action of gravity, and the interstitial fluid in the lower limb tissue is effectively drained. For example, the duration can be further set to 20 minutes, 30 minutes or more according to the specific situation and rehabilitation needs of the individual. By maintaining the lifting for a longer time, the venous pressure in the lower limbs can be effectively reduced, edema can be reduced, and a foundation can be laid for subsequent rehabilitation activities.

[0043] By setting the maintenance time of the supine lower limb lifting position to be greater than 15 minutes, the venous system of the lower limbs can obtain sufficient and continuous decompression effect. The longer duration makes the process of venous blood and lymph fluid returning to the heart under the guidance of gravity more thorough, effectively avoiding the problem of insufficient or short-term effect caused by maintaining the time too short. This helps to more deeply relieve the venous congestion in the lower limbs, reduce edema, and promote the effective circulation of interstitial fluid, thereby improving the long-term efficacy and stability of the method in preventing and relieving venous congestion in the lower limbs.

[0044] In some embodiments of the present application described above, the lower limbs are lifted to promote venous return by gravity, but passive lifting may not be able to fully activate the lower limb muscle pump, resulting in room for improvement in the efficiency of venous return, especially for users who need more powerful circulation.

[0045] To this end, the present application further proposes that the user synchronously performs active ankle pump movements while performing the above-mentioned maintenance step. The ankle pump movement includes alternating flexion and extension and circumferential movement of the ankle joint to further enhance the pumping effect of venous return by rhythmic contraction and relaxation of the calf muscles.

[0046] Wherein, synchronously performing active ankle pump movements means that the user consciously and actively performs ankle joint activities while maintaining the lower limb lifting position. This synchronization ensures that additional muscle pump action can be provided immediately on the basis of gravity-guided venous return, thereby avoiding the slowing of local blood flow that can be caused by long-term passive position. The initiative emphasizes that the user produces mechanical pressure through muscle contraction, rather than relying on external force, which helps to exercise the lower limb muscles and improve their ability to promote venous return.

[0047] The ankle pump exercise specifically includes alternating dorsiflexion and circumduction of the ankle joint. Alternating dorsiflexion refers to the rhythmic reciprocating movement of the ankle joint between dorsiflexion (toe pointing upwards, towards the calf) and plantar flexion (toe pointing downwards, away from the calf). For example, the user can slowly point the toes as high as possible, hold for a few seconds, then slowly straighten the toes as much as possible, hold for a few seconds, and repeat. Circumduction refers to the circular movement of the ankle joint, i.e. the toe makes a circle around the ankle joint, either clockwise or counterclockwise. These two movements can comprehensively and effectively activate the deep and superficial muscle groups of the lower leg, such as the gastrocnemius and soleus muscles, ensuring sufficient compression of the deep veins of the lower extremities.

[0048] The pumping effect of venous return is further enhanced by the rhythmic contraction and relaxation of the calf muscles. When the calf muscles perform alternating dorsiflexion and circumduction, their regular contractions squeeze the deep venous vessels in the muscles, pushing the venous blood upwards towards the heart. When the muscles relax, the venous vessel pressure decreases, and the venous blood below is pushed by gravity and residual pressure to supplement the emptied venous segment through the one-way action of the venous valve. This cycle of "contraction-relaxation-filling" forms an effective "muscle pump", significantly accelerating the centripetal return of venous blood.

[0049] By synchronously performing active ankle pump exercise during the maintenance of the lower limb lifting position, the calf muscle pump can be effectively activated to produce rhythmic contraction and relaxation. This active muscle activity cooperates with the gravitational guidance effect provided by the lower limb lifting to significantly enhance the centripetal flow efficiency of the venous blood and lymph in the lower extremities. Compared with simple passive lifting, this scheme can more effectively overcome the resistance caused by venous valve dysfunction or slow blood flow, effectively reduce venous stasis, accelerate the removal of metabolic waste, and thus more comprehensively and effectively prevent and relieve lower extremity venous congestion, improving the rehabilitation effect. In addition, active muscle movement helps maintain muscle tension, prevent muscle atrophy, and improve local blood circulation, further consolidating the rehabilitation effect.

[0050] In some embodiments of the present application described above, a method for preventing and relieving lower extremity venous congestion by adjusting body position is proposed. However, in actual application, if the user has certain specific health conditions, such as severe cardiovascular disease or eye disease, direct lower limb lifting may pose potential health risks, even exacerbate the original condition, thereby affecting the rehabilitation effect and user safety.

[0051] To this end, the present application further proposes that before performing the S1 step, a step S0 of health status assessment is further included, specifically, if the user is known to have severe cardiac dysfunction, uncontrolled hypertension or glaucoma, the user needs to consult a doctor before implementing the method.

[0052] The S0 health status evaluation step is used to ensure the safety and applicability of the rehabilitation body position method. This step is performed before the user starts the lower limb lifting body position, identifying specific groups of people who may face health risks due to body position adjustment. Specifically, if the user is known to have severe cardiac insufficiency, i.e., there is a significant obstacle to the heart's pumping function, lower limb lifting can cause a sudden increase in cardiac volume, thereby increasing the heart's load and causing or exacerbating adverse reactions such as heart failure. If the user has uncontrolled hypertension, i.e., their arterial blood pressure is persistently abnormally high and has not been effectively intervened by medication or lifestyle, lower limb lifting can further affect the stable regulation of blood pressure, even increasing brain blood vessel pressure in extreme cases. In addition, if the user has glaucoma, an eye disease characterized by elevated intraocular pressure, lower limb lifting can cause increased blood flow to the head, potentially increasing intraocular pressure and further damaging the optic nerve. Therefore, for any of the above conditions, the user must consult a professional physician's opinion before implementation, and the physician will evaluate the user's specific condition to determine whether they are suitable for the rehabilitation body position or under what conditions and in what way to perform it, in order to maximize the user's health and safety.

[0053] By introducing the health status evaluation step, the invention effectively solves the potential health risks when implementing the lower limb lifting body position rehabilitation method. This evaluation step serves as a front safety barrier, allowing for the timely identification of specific groups of people who are not suitable or need to be cautious in performing the body position adjustment, such as users with severe cardiac insufficiency, uncontrolled hypertension, or glaucoma. By requiring these users to be guided by a professional physician, the method avoids the potential increase in heart load, blood pressure fluctuations, or intraocular pressure caused by blind operation, thereby significantly improving the safety of the rehabilitation process. Not only does it protect the user's physical health, but it also ensures the effectiveness and applicability of the rehabilitation body position method, allowing it to be safely promoted to a wider population, while avoiding potential medical risks and complications, achieving a comprehensive consideration of the user's health and responsible self-rehabilitation.

[0054] The above technical solutions are further described below through a specific example: User A has been standing for a long time, often feeling sore, heavy, and slightly swollen in both lower limbs, suspecting a problem of lower limb venous stasis. To self-rehabilitate, user A decides to use the body position method.

[0055] First, before implementing the method, user A performed the health status evaluation step. User A confirmed that he did not have known diseases such as severe cardiac insufficiency, uncontrolled hypertension, or glaucoma, so he did not need to consult a physician and could safely proceed with the subsequent operations. This front evaluation step avoids the risks that may arise from performing operations in inappropriate situations, demonstrating the safety considerations of the solution.

[0056] Subsequently, user A enters a preparatory step, lying on a stable support plane, such as a bed or a yoga mat, in a supine position. This position provides a stable basis for the subsequent elevation of the lower limbs.

[0057] Next is the body position adjustment step. User A uses a specially designed lower limb support, which is a wedge-shaped cushion with a certain slope, and its internal structure is non-hollow design, which can provide uniform and stable support. User A places both lower limbs from ankle joint to hip joint region on the support, so that both lower limbs are elevated and maintained at a position higher than the heart level of user A. By adjusting the position of the support, ensure that the included angle between the longitudinal axis of the lower limbs and the horizontal plane is about 45 degrees, which can effectively utilize gravity to promote the venous blood and lymph of the lower limbs to flow back to the heart, and avoid the discomfort caused by too high angle. This clear support method and angle setting overcomes the limitation of the existing suggestions that the support method and elevation angle are described vaguely, ensuring the standardization and effectiveness of the operation.

[0058] After forming a stable supine lower limb elevation body position, user A enters the maintenance step. User A maintains this position for 20 minutes, which is longer than 15 minutes, which is sufficient to achieve sustained decompression of the lower limb venous system and promote fluid circulation. During this maintenance process, user A synchronously performs active ankle pump exercise. The exercise includes alternating flexion and extension and circumferential movement of the ankle joint, i.e. lifting the toes up, stepping down, and rotating the ankle joint clockwise and counterclockwise. Through the rhythmic contraction and relaxation of the calf muscles, the ankle pump exercise further enhances the pumping effect of venous return, which cooperates with the static body position elevation to significantly improve the blood return efficiency. This combination of static position and active exercise makes up for the shortcomings of existing methods that only focus on static position, maximizing the rehabilitation effect.

[0059] In some cases, if user A chooses a lateral position due to personal habits or physical condition limitations (such as waist discomfort), the method also provides an alternative body position step. User A can lie on the support plane in a lateral position, and place the upper single lower limb on another lower limb support, so that the side lower limb from ankle joint to hip joint region is elevated and maintained at a position higher than the heart level, forming a lateral single limb elevation body position. In this lateral single limb elevation body position, the other side lower limb on the lower side can be naturally flexed to maintain the balance and stability of the body in the lateral position. This adaptive body position scheme expands the applicability of the method, solving the problem of lack of clear solution for lateral position in existing technology.

[0060] Through the above systematic and standardized steps, user A can independently, safely and effectively prevent and alleviate lower limb venous congestion, which is better than the fragmented operation of elevating the lower limbs based on experience alone.

[0061] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of various changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.

Claims

1. A self-rehabilitation body position method for preventing and relieving lower limb venous congestion, characterized in that, Includes the following steps: S1. Preparatory steps: The user lies supine on the support surface; S2. Posture adjustment steps: The user uses a lower limb support to support both lower limbs, so that both lower limbs are raised from the ankle joint to the hip joint area and maintained at a position higher than the user's heart level, forming a stable supine lower limb raised position, so as to use gravity to guide the venous blood and lymph fluid of the lower limbs to return to the heart. S3. Maintenance Step: Maintain the supine lower limb elevated position for a preset duration to achieve continuous decompression of the lower limb venous system and promote fluid circulation; The lower limb support is configured as a non-perforated structure that can provide stable support or a perforated structure with ventilation and heat dissipation functions.

2. The autonomous rehabilitation body position method for preventing and relieving lower extremity venous congestion according to claim 1, characterized in that, The method also includes an alternative positioning step suitable for the lateral decubitus position: when the user selects the lateral decubitus position, the upper lower limb is placed on a lower limb support, so that the lower limb is raised from the ankle joint to the hip joint area and maintained in a position above the level of the heart, forming a lateral decubitus single limb elevation position.

3. The autonomous rehabilitation body position method for preventing and relieving lower extremity venous congestion according to claim 2, characterized in that, In the lateral single-limb elevation position, the lower limb on the opposite side can be naturally flexed to maintain the body's balance and stability in the lateral position.

4. The self-rehabilitation posture method for preventing and alleviating lower extremity venous congestion according to claim 1, characterized in that, In step S2, the lifting position is such that the angle between the longitudinal axis of both lower limbs and the horizontal plane is between 45 degrees and 90 degrees.

5. A self-rehabilitation posture method for preventing and alleviating lower extremity venous congestion according to claim 1, characterized in that, The preset duration in step S3 is greater than 15 minutes.

6. A self-rehabilitation posture method for preventing and alleviating lower extremity venous congestion according to claim 1 or 2, characterized in that, While performing the maintenance steps, the user simultaneously performs active ankle pumping movements, which include alternating flexion, extension, and circumduction of the ankle joint to further enhance the pumping effect of venous return through rhythmic contraction and relaxation of the calf muscles.

7. A self-rehabilitation posture method for preventing and alleviating lower extremity venous congestion according to claim 1, characterized in that, Before performing step S1, there is also a step S0: a health status assessment step, specifically, if the user is known to have severe heart failure, uncontrolled hypertension, or glaucoma, they should consult a doctor before implementing this method.
