Description

Technical Field

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

[0002] As an important joint for movement, the knee joint is prone to discomfort such as aversion to cold, chills, and stiffness due to invasion of cold pathogens, stagnation of Qi in the meridians, and insufficient Yang Qi. Long-term cold stagnation and meridian obstruction can also lead to poor blood circulation in the joint, exacerbating problems such as difficulty in flexion and extension, and worsening with exposure to cold. These problems are particularly common among middle-aged and elderly people, those who sit or stand for long periods, those working in cold and damp environments, and those who work outdoors in autumn and winter. Current technologies for warming and protecting the knee joint with traditional Chinese medicine mainly include oral preparations, topical ointments, soaking preparations, and specialized therapeutic topical medications. While each has some conditioning effect, they all have significant technical shortcomings and cannot meet the daily needs for warming, dispelling cold, and gentle protection of the knee joint.

[0003] Oral warming and dispelling Chinese herbal medicines exert their 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 burden the gastrointestinal tract, liver, and kidneys with metabolic stress, and may cause potential internal side effects such as abdominal distension and aversion to cold. Therefore, they are not suitable for daily gentle warming and nourishing of the superficial cold stagnation of the knee joint.

[0004] Topical ointments are a commonly used form of warming and regulating the knee joint in clinical practice. They are mostly based on oils, rubber, etc., and are made into ointments containing warming and dispelling Chinese herbal ingredients and applied to the knee joint. However, due to the stickiness and semi-solid nature of the base itself, these ointments are prone to migration and falling off during knee flexion and extension. They not only easily stain clothes but are also difficult to clean, resulting in a poor user experience. At the same time, the effective ingredients in ointments are mostly released in a single saturation, and the absorption by the stratum corneum of the skin is limited, so the efficacy decays rapidly. They usually need to be replaced every 4-8 hours, and the duration of efficacy is short, so they cannot achieve long-term warming and protective effects. For example, the invention patent application with publication number CN102362997A discloses a thick paste-like medicine made from more than ten kinds of medicinal materials such as Erythrina bark, Clematis armandii, Lycopodium clavatum, raw Aconitum carmichaelii, and raw Aconitum kusnezoffii, combined with rice vinegar. It needs to be applied to the knee joint and used in conjunction with alcohol moxibustion to complete the treatment. Because the medicine is a thick paste-like ointment, the thickness of the application is up to 1 cm, which easily sticks to the skin and stains clothes. After use, it also requires tedious cleaning, and the operation is highly professional, so it cannot be used for daily warming and nourishing.

[0005] Immersion preparations, such as foot bath warming formulas, can achieve whole-body warming and cold dispelling through the absorption of Chinese medicine ingredients by the skin of the feet. However, the effect is mainly concentrated on the feet, with very poor targeting of the knee joint. In addition, containers and hot water are required, so they can only be used in fixed indoor settings and cannot be operated in daily activities, thus limiting their use. Furthermore, the warming effect of short-term immersion is difficult to sustain on the knee joint, and cannot meet the daily needs for cold protection. 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 process of the knee brace for warming and strengthening the knee provided in Embodiment 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 warming and strengthening the knees provided in Example 1 of this invention is made from the following raw materials in parts by weight: 25 parts of dried mugwort leaves, 10 parts of white chrysanthemum, 10 parts of longan shell, and 5 parts of Sichuan pepper.

[0020] The formula contains 25 parts of aged mugwort leaves, which are pungent, bitter, and warm in nature. It 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 unblocking the meridians of the knee joint and dispelling superficial cold pathogens. After aging, the mugwort leaves become milder and less drying, avoiding excessive warming that could damage the skin. Its warming properties directly warm the local meridians of the knee joint, dispelling superficial cold pathogens that obstruct the knee area, thus fundamentally improving problems such as knee coldness, stiffness after prolonged sitting, and aversion to cold. Its pungent and dispersing properties unblock the qi and blood vessels in the knee area, relieving mild, dull pain and limited range of motion caused by cold stagnation. Simultaneously, its volatile oil components are gently released, making it suitable for external use as a knee brace worn close to the body. The medicinal effects are activated by body temperature, achieving long-lasting warming and nourishing without being harsh, making it suitable for daily long-term wear.

[0021] Five parts of Sichuan pepper, pungent and warm in nature, enters the spleen, stomach, and kidney meridians. It serves as an auxiliary warming and unblocking herb in the formula. The dosage is small but the effect is specific. Its pungent and warm nature can assist the aged mugwort leaves in enhancing the warming and dispelling cold power, directly targeting the cold stagnation in the knee joint. At the same time, it can promote qi circulation, warm the middle and relieve pain, alleviating the mild swelling and pain in the knee joint and tightness in the meridians caused by cold pathogens blocking the meridians. The aromatic and penetrating nature of Sichuan pepper is stronger, which can promote the local qi circulation in the knee joint, making it easier for the warming and unblocking power of the aged mugwort leaves to penetrate, helping the cold pathogens to dissipate with the qi. The combination of the two, one as the main and one as the auxiliary, makes the warming, dispelling cold, unblocking the meridians and relieving pain more synergistic. Moreover, the dosage is controlled to avoid excessive warming and drying, which may cause local dryness and heat.

[0022] Ten parts of longan shell, sweet in taste and warm in nature, enter the heart and spleen meridians. It is a mild adjuvant in the formula, taking into account both the function of regulating qi and protecting the skin. Its warm nature is gentle and does not have a strong warming effect. It can relieve local qi stagnation in the knee joint. Combined with dried mugwort leaves and Sichuan pepper, the warming effect is more gentle, avoiding skin discomfort caused by the direct penetration of warming drugs into the meridians. At the same time, longan shell can nourish the skin and reduce the irritation of the pungent and warm nature of dried mugwort leaves and Sichuan pepper on the skin of the knee joint, improving the comfort of wearing the knee brace. It is especially suitable for sensitive skin and long-term use by middle-aged and elderly people. In addition, its texture is light and soft. After being chopped and put into the medicine bag, it can increase the fluffiness and make the medicine bag fit the knee joint better, improving the wearing experience.

[0023] White chrysanthemum (10 parts), sweet and bitter in taste, slightly cold in nature, enters the lung and liver meridians. It serves as the guiding herb in the formula, harmonizing the other herbs and also acting as an adjuvant. Its slightly cold nature neutralizes the warming and drying properties of dried mugwort and Sichuan pepper, preventing localized dryness and itching of the knee joint due to prolonged warming, ensuring the entire formula is warm without being drying and has a mild medicinal effect. At the same time, white chrysanthemum's light and refreshing properties clear and dredge the meridians, relieving stiffness in the knee joint caused by cold stagnation and qi stagnation, and assisting in clearing the meridians in the knee area, allowing for smoother blood and qi circulation. Combined with warming and dredging herbs, it forms a combination of warming and clearing, dispelling cold pathogens and dredging the meridians, preventing stagnation in the meridians after the cold stagnation is relieved. In addition, its light fragrance neutralizes the pungent aroma of mugwort and Sichuan pepper, making the herbal packet more mellow and enhancing the user experience.

[0024] This embodiment provides a knee brace for warming and strengthening the knee with a traditional Chinese medicine composition, including a knee brace body and a drug-containing part disposed on the knee joint of the knee brace body. The drug-containing part is filled with traditional Chinese medicine powder made from the warming and strengthening knee traditional Chinese medicine composition. The drug-containing part is a non-woven fabric medicine bag that is detachably connected to the inside of the knee brace body. The non-woven fabric medicine bag is a breathable and leak-proof medical-grade non-woven fabric.

[0025] Before using the knee brace provided in this embodiment, which is a traditional Chinese medicine composition for warming 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. The packet is then securely attached. 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 of 4-8 hours is recommended, but intermittent wear is also possible as needed. Because the effects of the herbal powder are released slowly, a single herbal medicine packet is recommended to be used continuously for 2-3 days. Once the medicinal smell fades, it can be removed and replaced with a new herbal medicine packet. After removing the herbal 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, these ointments tend to migrate and fall 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, which 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. Furthermore, the active ingredients in ointments are released in a single saturation, and the efficacy diminishes after 4-8 hours, requiring frequent replacement, which can pull on the skin and cause discomfort. This knee brace, on the other hand, uses a slow and continuous release of herbal powder. Relying on body temperature and the sealed environment of the knee brace, the active ingredients can be released stably for 2-3 days, extending 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:

[0026] like Figure 1 As shown, a preparation process for a knee brace that strengthens and warms the knee is characterized by the following steps: S1: Selected raw materials include dried mugwort leaves, white chrysanthemum, longan shells, and Sichuan pepper. Moldy, insect-infested, odorous, impurities, and non-medicinal parts are removed. After rinsing with clean water to remove mud and surface dust, the raw materials are drained. Heavy metal and pesticide residue testing of the raw materials meets GB2762 and GB2763 standards. Manual removal of moldy, insect-infested, odorous, impurities, and non-medicinal parts removes deteriorated or ineffective portions of the raw materials, as well as impurities with no medicinal value. This ensures that only qualified, effective, and pure medicinal raw materials enter subsequent processes, avoiding the dilution of effective components by ineffective impurities and guaranteeing the efficacy concentration and stability of the herbal 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 herbal powders, thus avoiding knee irritation during use. The product is designed for close-fitting use on the knee joint, preventing contamination of equipment during crushing and drying, and avoiding clumping caused by dirt mixing with raw materials. This ensures smooth operation of subsequent processes. Draining excess water prevents the raw materials from becoming too moist, which could lead to sticking to the screen or clumping during crushing. The product is tested for heavy metals (lead, mercury, cadmium, etc.) and pesticide residues, meeting GB2762 and GB2763 standards. This safety control is based on the product's close-fitting nature and long-term external skin contact. Excessive levels of heavy metals and pesticide residues can be absorbed in trace amounts through long-term skin contact, posing potential health risks. Passing national standard safety testing completely eliminates these risks, ensuring the product meets the safety requirements for external use and is suitable for long-term use by people with different skin types (including sensitive skin and the elderly).

[0027] S2: After cleaning all the raw materials in step S1, mix them together and chop them to obtain Chinese herbal powder with a particle size of 0.5-1cm. Chopping slightly breaks down the tissue structure of the herbs, making it easier for the volatile oils of Artemisia argyi, the aromatic components of Sichuan pepper, and the soothing components of chrysanthemum to be slowly released by body temperature when the knee brace is worn. This ensures a warming effect without causing a strong odor or irritation due to rapid release of the components. Controlling the particle size to 0.5-1cm balances efficacy and wearing comfort. The 0.5-1cm powder has a loose texture and will not harden or press on the knee joint after being placed in the herbal pack, allowing for a comfortable flexion and extension without any foreign body sensation. The moderate particle size of 0.5-1cm reduces leakage and dust caused by excessively fine powder, and prevents the herbal powder from directly contacting the skin through the non-woven fabric and irritating it.

[0028] 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 use... 60Sterilization was performed using Co-γ rays at a dose of 5 kGy. After sterilization, no pathogenic bacteria were detected, and the total number of molds and yeasts met the relevant safety requirements for food contact fillers. A low-temperature drying process of 45℃ was used to maximize the retention of volatile active ingredients in the raw materials (volatile oils and aromatic warming components from dried mugwort leaves, Sichuan pepper, and white chrysanthemum), avoiding decomposition and inactivation due to high temperatures. The powder was spread in a 2cm layer with hot air circulation, ensuring even heating and moisture distribution throughout the layer, preventing localized under-drying or over-drying, ensuring consistent moisture content across the entire batch, and preventing clumping and adhesion caused by thick-layer drying. Moisture content was controlled to ≤12% to inhibit moisture absorption, mold growth, and clumping during subsequent sealing, storage, and application, preventing spoilage and off-odors caused by excessive moisture. Commonly used national standards were employed. 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.

[0029] S4: The sterilized Chinese herbal 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 a Chinese herbal medicine bag. The filling amount of each non-woven fabric medicine bag is 50g. The medical-grade non-woven fabric has the characteristics of being breathable but not permeable to residue, soft and skin-friendly, and non-irritating. It can not only allow the aromatic and warming components of mugwort and Sichuan pepper to be slowly released and reach the knee, but also completely block the leakage of Chinese herbal medicine powder and avoid staining the skin and clothing.

[0030] 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 warming and strengthening knee brace.
