Description

Technical Field

[0001] This invention relates to the field of pharmaceutical technology, and in particular to a traditional Chinese medicine composition for dispelling dampness and strengthening the knees, as well as knee braces using the same composition and their preparation process. Background Technology

[0002] The knee joint, as an important joint for movement, is prone to discomfort such as heaviness, soreness, and coldness due to spleen deficiency and dampness accumulation, or invasion of cold and dampness. Prolonged exposure can lead to impaired joint movement and affect daily activities. These problems are particularly common among middle-aged and elderly people, those who sit or stand for long periods, and those working in cold and damp environments. Current traditional Chinese medicine treatments for the knee joint mainly involve oral preparations, topical ointments, and soaking preparations. While each has some therapeutic effect, they all have significant technical limitations and cannot fully meet the daily needs for knee joint maintenance and strengthening.

[0003] Oral Chinese medicine preparations exert systemic conditioning effects through gastrointestinal absorption. However, the concentration of their active ingredients reaching the knee joint after being metabolized by the liver and kidneys is extremely low, resulting in poor targeting. Furthermore, long-term use can easily cause metabolic burden on the gastrointestinal tract, liver, and kidneys, and there are potential oral side effects. Therefore, they are not suitable for daily gentle conditioning of dampness and heaviness in the knee joint.

[0004] Topical ointments are a common form of knee joint treatment in clinical practice. They typically use oils or rubber as a base, with herbal ingredients applied to the knee joint. However, due to the stickiness and semi-solid nature of the base, these ointments are prone to migration and detachment during knee flexion and extension, easily staining clothing and being difficult to clean, resulting in a poor user experience. Furthermore, the active ingredients in these ointments are often released only once, with limited absorption by the skin's stratum corneum, leading to rapid efficacy decay. They typically need to be replaced every 4-8 hours, resulting in a short duration of effect and failing to provide long-term treatment. For example, patent application CN102362997A discloses a thick paste-like medicine made from more than ten herbs, including Erythrina bark, Clematis armandii, Lycopodium clavatum, raw Aconitum carmichaelii, and raw Aconitum kusnezoffii, combined with rice vinegar. This medicine needs to be applied to the knee joint and used in conjunction with alcohol moxibustion for treatment. Because the medicine is a thick paste, the application thickness reaches 1 cm, easily sticking to the skin and staining clothing, requiring tedious cleaning after use.

[0005] Soaking preparations, such as foot bath formulas, can remove dampness from the whole body by absorbing the Chinese medicine ingredients through the skin of the feet. However, the main area of ​​action is concentrated on the feet, and they are not very effective for the knee joint. In addition, containers and hot water are required, so they can only be used in fixed indoor settings and cannot be used in daily activities. Their use is limited and they are not suitable for the daily maintenance needs of the knee joint due to dampness. Summary of the Invention

Attached Figure Description

[0016] The invention, its features, shape, and advantages will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings. Like reference numerals denote like parts throughout the drawings. The drawings are not intentionally drawn to scale; the focus is on illustrating the spirit of the invention.

[0017] Figure 1 This is a wireframe flowchart of the preparation method of the traditional Chinese medicine composition for removing dampness and strengthening the knees provided in Example 2 of the present invention. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but these are not intended to limit the scope of the invention. Example 1:

[0019] The traditional Chinese medicine composition for removing dampness and strengthening the knees provided in Example 1 of this invention is made from the following raw materials in parts by weight: 18 parts of Artemisia argyi, 12 parts of Poria cocos, 12 parts of roasted Coix lacryma-jobi, 6 parts of dried ginger, and 6 parts of dried tangerine peel.

[0020] Artemisia argyi (18 parts), with a pungent and bitter taste and warm nature, enters the liver, spleen, and kidney meridians. As the principal herb in the formula and used in the largest quantity, it is the core ingredient for warming and dispersing cold and dampness in the knee and unblocking the meridians of the joints. Its warming properties can directly warm the local meridians of the knee joint, dispel the cold and dampness obstructing the knee, and improve the knee joint's fear of cold, coldness, and heaviness when bending and stretching from the root. Its pungent and dispersing properties can dredge the qi, blood, and tendons of the knee, relieving the joint soreness and dull pain caused by dampness obstruction. At the same time, the warming properties of Artemisia argyi can help the spleen yang to transport and transform, indirectly enhancing the spleen and stomach's ability to remove dampness. It takes into account both dispersing local cold and dampness externally and helping to remove dampness from the root internally. It also contains volatile oil active ingredients, making it suitable for wearing close to the body on the knee. It releases its medicinal effects slowly through body temperature, and is gentle and non-harsh, making it suitable for daily maintenance.

[0021] Poria cocos (12 parts) is sweet and bland in taste, neutral in nature, and enters the heart, spleen, and kidney meridians. It is the core spleen-strengthening and dampness-removing herb in the formula, mainly focusing on strengthening the spleen and replenishing qi, and promoting diuresis and eliminating dampness. The spleen is responsible for transporting and transforming water and dampness. Dampness in the knee joint often stems from spleen deficiency and abnormal water and dampness metabolism, which then flows down to the joint. Poria cocos is sweet and nourishing, and promotes diuresis and eliminates dampness. It can not only replenish the qi of the spleen and stomach and enhance the core function of the spleen and stomach in transporting and transforming water and dampness, thus preventing the generation of dampness from the root, but also excrete the water and dampness retained in the body through urination. Moreover, its medicinal properties are mild, removing dampness without harming the spleen yang. When combined with Artemisia argyi, it strengthens the spleen and stomach internally to remove the source of dampness, and disperses cold and dampness in the knee externally, achieving synergistic effect of removing dampness from both internal and external sources.

[0022] 12 portions of roasted Job's tears, sweet and bland in taste, and cool in nature, are roasted to reduce their coldness and enhance their spleen-strengthening effect. They enter the spleen, stomach, and lung meridians. When combined with Poria cocos, they form a dual-herb formula to strengthen the spleen and dispel dampness. The dosage of both is the same, which strengthens the core effect of dispelling dampness. Roasted Job's tears have the dual effects of strengthening the spleen and promoting diuresis and dispelling dampness. They can assist Poria cocos in strengthening the spleen and stomach, and can also reach the joints directly, draining dampness and turbidity from the knee joint, relieving swelling, soreness, and limited mobility caused by dampness. At the same time, their sweet taste can nourish the tendons and veins, taking into account both dispelling dampness and strengthening tendons and knees. When combined with Poria cocos, the spleen-strengthening and dampness-dispelling effects are more gentle and lasting. Moreover, roasting makes them more compatible with the digestive characteristics of the spleen and stomach, avoiding the cold nature of raw Job's tears from damaging the spleen yang.

[0023] Six parts dried ginger, pungent and hot in nature, enters the spleen, stomach, heart, and lung meridians. It serves as an adjuvant in the formula to warm the yang, dispel cold, and assist the spleen in its function. The dosage is small but the effect is specific. Its warming nature can tonify the spleen yang. When the spleen yang is warmed, its ability to transform and transport water and dampness is stronger. It internally assists the spleen-strengthening and dampness-removing effects of Poria and roasted coix seed. At the same time, it can work together with mugwort to warm and dispel cold and dampness in the knee. One warms the spleen yang and the other warms the meridians. The two warm the yang and dispel cold from the inside and outside, solving the core problem of cold and dampness binding and obstructing the knee meridians. This allows the dampness to be more easily transformed and expelled without the support of cold stagnation. The warming nature of dried ginger can also neutralize the slightly cooling nature of roasted coix seed, making the whole formula mild and without any imbalance of cold or heat, making it suitable for long-term daily maintenance.

[0024] Six parts of dried tangerine peel, with a pungent and bitter taste and warm nature, enters the spleen and lung meridians. It serves as the guiding herb in the formula, regulating qi and resolving dampness, and harmonizing the other herbs. It also has the function of assisting and guiding. Its pungent and bitter properties can regulate qi, strengthen the spleen, dry dampness, and harmonize the middle jiao. It addresses the problem of qi stagnation and dampness obstruction that easily occurs during the process of eliminating dampness due to spleen deficiency. The spleen and stomach need smooth qi to transport and transform water and dampness. If qi stagnates, dampness will accumulate. Dried tangerine peel can soothe the qi of the spleen and stomach, allowing the spleen-strengthening and dampness-resolving effects of Poria and roasted coix seed to be better exerted. At the same time, it can dry dampness and resolve turbidity, and help clear dampness in the spleen, stomach, and joints. In addition, dried tangerine peel can harmonize the properties of all the herbs in the formula, moderate the warming and invigorating properties of mugwort and dried ginger, and avoid excessive warming and drying. It also connects the effects of spleen-strengthening herbs and warming and invigorating herbs, so that the spleen-strengthening and dampness-resolving effects and the warming and invigorating effects of strengthening the knees can work smoothly and synergistically. This makes the whole formula nourishing without stagnation, warming without drying, and removing dampness without harming the body's vital energy.

[0025] This embodiment provides a knee brace for removing dampness and strengthening the knee with a traditional Chinese medicine composition, including a knee brace body and a drug receiving part disposed on the knee joint of the knee brace body. The drug receiving part is filled with traditional Chinese medicine powder made of the traditional Chinese medicine composition for removing dampness and strengthening the knee. The drug receiving part is a non-woven fabric medicine bag that can be detachably connected to the inside of the knee brace body. The non-woven fabric medicine bag is a breathable and powder-proof medical-grade non-woven fabric.

[0026] Before using the knee brace provided in this embodiment, which is a traditional Chinese medicine composition for removing dampness and strengthening the knee, the prepared medical-grade non-woven fabric herbal medicine packet is embedded into the medicine receiving part of the knee brace corresponding to the knee joint area. It is then fitted and fixed in place. The knee brace with the medicine packet is then worn directly on the knee joint. The elasticity of the knee brace is adjusted to ensure a close fit to the leg and to accommodate natural flexion and extension of the knee joint. It can be worn all day, during daily work, walking, prolonged sitting, and sleep. A single continuous wear time is recommended to be 4-8 hours, or it can be worn intermittently as needed. Because the effects of the herbal powder are released slowly, a single medicine packet is recommended to be used continuously for 3-5 days. Once the medicinal smell fades, it can be removed and replaced with a new medicine packet. After removing the medicine packet, the knee brace itself can be washed, dried, and reused. Compared to existing oral preparations, which can easily cause metabolic burden on the gastrointestinal tract, liver, and kidneys with long-term use and have potential side effects such as abdominal distension, diarrhea, and liver and kidney damage, this knee brace is an external topical medication that does not go through gastrointestinal tract and liver and kidney metabolism, has no systemic absorption burden, and has no oral side effects. Compared to existing topical ointments, which are based on oils and rubber and have strong adhesion, easily migrating and falling off during knee flexion and extension, staining clothes and sheets and being difficult to clean, requiring tedious cleaning after use, this knee brace uses a medical-grade non-woven fabric sealed medicine pack. It is breathable but not powder-permeable, non-sticky, and non-greasy, and does not come into contact with the skin or adhere to clothing, completely solving the problem of staining. No cleaning is required after use. In addition, the active ingredients of ointments are released in a single saturation, and the efficacy diminishes after 4-8 hours, requiring frequent replacement. Moreover, the skin may be pulled and irritated during replacement. This knee brace contains herbal powder that releases slowly and continuously. Relying on body temperature and the sealed environment of the knee brace, the active ingredients can be released stably for 3-5 days, increasing the duration of efficacy several times, and eliminating the need for frequent replacement. Compared to existing foot bath preparations, which require containers and hot water and can only be used in fixed indoor settings, with each soak lasting only 15-20 minutes, making it difficult to achieve long-term conditioning effects and integrate into daily work, outings, and other scenarios, this knee brace can be worn all day long and is unrestricted in all scenarios such as work, travel, prolonged sitting, and sleep. Example 2:

[0027] like Figure 1 As shown, a preparation process for a traditional Chinese medicine composition for dispelling dampness and strengthening the knees is characterized by comprising the following steps: S1: Select raw materials including mugwort leaves, poria cocos, roasted coix seed, dried ginger, and dried tangerine peel. Remove moldy, insect-infested, odorous, impurities, and non-medicinal parts. Rinse with clean water to remove mud and surface dust, then drain. Test the raw materials for heavy metals and pesticide residues, ensuring they meet GB2762 and GB2763 standards. Manually removing moldy, insect-infested, odorous, impurities, and non-medicinal parts removes deteriorated or ineffective parts of the raw materials, as well as impurities with no medicinal value (such as withered branches of mugwort leaves and hardened outer skin of poria cocos). This ensures that only qualified, effective, and pure medicinal raw materials enter subsequent processes, avoiding the dilution of effective ingredient content by ineffective impurities and guaranteeing the efficacy concentration and stability of the Chinese medicine powder from the source. Rinsing with clean water removes mud, dust, and other external contaminants from the surface of the raw materials, improving the hygiene and cleanliness of the finished product and preventing mud and dust from mixing into subsequent Chinese medicine powders. To avoid irritating the skin of the knee joint during use, and to prevent contamination of the equipment during crushing and drying, or the formation of clumps by mixing with raw materials, ensuring the smooth progress of subsequent processes, the product is designed to prevent excessive moisture content in the raw materials, which could lead to sticking to the screen or clumping during subsequent crushing. The product is tested for heavy metals (lead, mercury, cadmium, etc.) and pesticide residues, and complies with GB2762 and GB2763 standards. This safety control is based on the product's characteristic of being worn close to the knee joint and in long-term external contact with the skin. If heavy metals and pesticide residues exceed the standards, long-term skin contact can lead to trace amounts being absorbed by the body, posing potential health risks. Passing national standard safety testing completely eliminates such risks, ensuring the product meets the safety requirements for external care and is suitable for long-term use by people with different skin types (including sensitive skin and the elderly).

[0028] S2: Mix all the raw materials purified in step S1 and then pulverize them. Pass the mixture through a 20-mesh sieve and retain it through a 40-mesh sieve to obtain a traditional Chinese medicine powder with a particle size of 20-40 mesh. Mixing and pulverizing all the purified raw materials of Artemisia argyi, Poria cocos, roasted Coix seed, dried ginger, and dried tangerine peel breaks down the plant cell walls of each raw material, allowing the volatile components (Artemisia argyi volatile oil) and water-soluble components (Poria cocos polysaccharides, dried ginger gingerol) to be fully exposed. This solves the problem of the difficulty in releasing effective components when the raw materials are intact. Simultaneously, pulverizing after mixing ensures that the effective components of the five herbs are evenly distributed in the powder, guaranteeing a consistent efficacy ratio in each portion of the powder and avoiding localized concentration of single herb components. This ensures a balanced and synergistic effect when the knee brace is used. The particle size control, including passing through a 20-mesh sieve and retaining a 40-mesh sieve, avoids defects such as powder that is too fine or too coarse. This is suitable for drug delivery methods that are wrapped in medical-grade non-woven fabric and placed against the knee joint. It eliminates powder that is too fine (>40 mesh) to prevent easy leakage and dust generation, and avoids fine powder adhering to the skin through the non-woven fabric and causing irritation during use. It also prevents fine powder from clumping during drying and packaging, ensuring the breathability of the drug pack. It avoids particles that are too coarse (<20 mesh) to prevent the hard texture of coarse particles from causing pressure on the knee joint when wearing the drug pack, thus improving wearing comfort.

[0029] S3: Spread the Chinese herbal powder obtained in step S2 into a 2cm thick layer, place it in a hot air circulating low-temperature drying device, control the temperature at 45℃, and dry until the moisture content of the Chinese herbal powder is ≤12%; then sterilize it by irradiation with 60Co-γ rays at a dose of 5kGy. After sterilization, pathogenic bacteria should not be detected, and the total number of molds and yeasts should meet the relevant safety requirements for food contact fillers; the 45℃ low-temperature drying is used to maximize the retention of volatile effective components (volatile oil of Artemisia argyi and volatile oil of dried tangerine peel) and active components (Poria cocos polysaccharide and gingerol of dried ginger) in the raw materials, and avoid high Temperature control prevents the decomposition and inactivation of ingredients, ensuring that the efficacy of the herbal powder in dispelling dampness and strengthening the knees is not diminished, meeting the need for slow-release efficacy in external knee braces. A 2cm layer of powder, combined with hot air circulation, ensures even heating and moisture distribution throughout the layer, preventing localized insufficient or excessive drying and guaranteeing consistent moisture content across the entire batch. This also prevents clumping and sticking caused by thick layers of drying. Moisture content is controlled to ≤12% to inhibit moisture absorption, mold growth, and clumping during subsequent sealing, storage, and wear, preventing spoilage and unpleasant odors caused by excessive moisture. The formula uses commonly used national standards. 60 Co-γ ray irradiation sterilization can kill pathogenic bacteria, molds, yeasts and other microorganisms in Chinese medicine powders without destroying the effective components or introducing any chemical residues. After sterilization, the test requirements are that pathogenic bacteria must not be detected and the total number of molds and yeasts must meet the standards for food contact fillers.

[0030] S4: The sterilized Chinese medicine powder from step S3 is filled into a medical-grade non-woven fabric medicine bag according to the preset filling amount, and sealed to obtain the Chinese medicine medicine bag. The filling amount of each non-woven fabric medicine bag is 18g. The powder filling according to the preset filling amount of 18g per bag is a precise dosage design based on the compatibility ratio of the dampness-removing and knee-strengthening formula and the efficacy requirements of local drug administration to the knee joint. This ensures that the effective ingredient content of a single medicine bag can meet the maintenance needs for 3-5 days, while avoiding excessive dosage that would make the medicine bag too thick and affect wearing comfort. The use of medical-grade non-woven fabric as the medicine bag carrier is suitable for the external use needs of knee braces, taking into account both drug release and user experience.

[0031] S5: Fix the Chinese medicine pack obtained in step S4 into the medicine receiving part of the knee brace body corresponding to the knee joint, thus completing the preparation of the dampness-removing and knee-strengthening knee brace.
