Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine technology, and more specifically to a cold-dispelling and dampness-removing patch. Background Technology

[0002] In daily life, "cold and dampness invasion" is a common cause of bodily discomfort. Prolonged exposure to damp and cold environments, insufficient warmth in winter, and consumption of raw or cold foods can all lead to the retention of cold and dampness in the body, causing symptoms such as joint pain, muscle aches, and abdominal pain. The incidence of cold and dampness-related discomfort is particularly high among middle-aged and elderly people, manual laborers, and office workers who sit for long periods, significantly impacting their quality of life.

[0003] Currently available topical patches for relieving cold have many shortcomings:

[0004] 1. Simple heating mechanism: Most products rely solely on the pungent stimulation of Chinese herbal ingredients to generate surface warmth (such as simply containing ginger or capsaicin), or only generate physical heat through the oxidation of iron powder. The former has a short duration of warmth (usually 2-3 hours), while the latter has no pharmacological conditioning effect of Chinese herbal medicine, and the effect of dispelling cold and dampness is limited.

[0005] 2. Imbalanced formula design: Some products only focus on "dispelling evil" (dispelling cold and dampness) and lack "strengthening" ingredients (such as tonifying the liver and kidneys and strengthening muscles and bones), resulting in recurring symptoms; other products have mixed ingredients and do not distinguish between "cold-dampness syndrome" and "damp-heat syndrome". People with damp-heat constitution are prone to adverse reactions such as redness, swelling and itching after misuse.

[0006] 3. Insufficient safety performance: Some products do not take skin irritation into account, do not specify allergy testing requirements, or do not limit contraindications (such as applicable scope for pregnant women and infants), which increases the risk of use;

[0007] 4. Poor drug penetration: Most Chinese medicine ingredients are added in the form of raw powder without being optimized by extraction process, making it difficult for the effective ingredients to be absorbed through the skin, resulting in the problem of "feeling heat after application but no relief of symptoms".

[0008] Therefore, there is an urgent need to develop a topical patch that combines the classic compatibility theory of traditional Chinese medicine with modern materials science and transdermal technology. This patch can exert the pharmacological effects of dispelling cold and dampness, promoting blood circulation and relieving pain from multiple targets, and can also continuously provide heat energy through physical means to promote drug penetration, thereby achieving rapid onset and long-lasting effects. Summary of the Invention

[0009] In view of this, the present invention provides a cold-dispelling and dampness-removing patch that can exert pharmacological effects of dispelling cold and dampness, promoting blood circulation and relieving pain from multiple targets, and can also continuously provide heat energy through physical means to promote drug penetration, thereby achieving rapid onset and long-lasting effect.

[0010] To achieve the above objectives, the present invention provides the following technical solution, including spunlace fabric, a drug core layer, a drug core rubber ring, and an adhesive backing;

[0011] The core layer, the adhesive layer coated with medical pressure-sensitive adhesive, and the anti-adhesive layer covering the adhesive layer;

[0012] The core layer consists of a core Chinese medicine component and an synergistic auxiliary component.

[0013] The core Chinese herbal ingredients consist of Angelica pubescens, Taxillus chinensis, Ligusticum chuanxiong, stir-fried Sichuan pepper, and Artemisia argyi.

[0014] The synergistic auxiliary component consists of ginger powder, tourmaline, and wood vinegar powder;

[0015] The manufacturing process of the cold-dispelling and dampness-removing patch includes the following steps:

[0016] S1 selects high-quality materials;

[0017] S2 grinding and pulverizing;

[0018] S3 is mixed in proportion;

[0019] S4 package;

[0020] S5 pre-assembled;

[0021] S6 sealed packaging.

[0022] Preferably, in the above S1 screening of high-quality materials, according to the preset quality ratio, high-quality, mold-free, and conforming to the relevant quality standards of the Chinese Pharmacopoeia, including superior Angelica pubescens, Taxillus chinensis, Ligusticum chuanxiong, roasted Sichuan pepper, Artemisia argyi, as well as food-grade or pharmaceutical-grade ginger powder, tourmaline powder, and wood vinegar powder are selected respectively.

[0023] Preferably, in the above S2 grinding and pulverizing process, Angelica pubescens, Taxillus chinensis, Ligusticum chuanxiong, roasted Sichuan pepper, and Artemisia argyi are cleaned, dried, and then pulverized and ground separately, then passed through a 150-mesh sieve, and then the tourmaline and wood vinegar powder are pulverized into an ultrafine powder state using an ultra-micro pulverizer.

[0024] Preferably, in the above S3, the ground and sieved medicinal powder, pulverized tourmaline, wood vinegar powder and ginger powder are mixed in proportion to obtain a mixed Chinese medicine powder. Then, it is dried at 45-55℃ and relative humidity below 30% for 4-6 hours to reduce its moisture content to below 8% to obtain the final medicinal powder.

[0025] Preferably, in the above-mentioned S4 encapsulation, the obtained dried drug powder is quantitatively filled into a circular drug bag made of breathable hydroentangled fabric and encapsulated into a drug core.

[0026] Preferably, in the above-mentioned S5 pre-assembly molding, a low-allergenic medical spunlace fabric is selected as the substrate, and a medical acrylate pressure-sensitive adhesive is uniformly coated on one side to form an adhesive layer, and then dried and cured in a dryer at 60-70°C.

[0027] Preferably, in the above-mentioned S6 sealing packaging, the drug core made in S4 is fixed to the central area of ​​the adhesive-coated hydroentangled fabric substrate made in S5, the composite is then cut to the specified size, and finally, release paper or release film is covered on the outside of the adhesive layer as an anti-sticking layer, and then it is placed in an aluminum foil composite film bag and vacuumed or nitrogen-filled and sealed.

[0028] Preferably, the mass ratio of each raw material component in the above-mentioned core layer is as follows: Angelica pubescens 12-18 parts, Taxillus chinensis 12-18 parts, Ligusticum chuanxiong 10-14 parts, roasted Sichuan pepper 6-10 parts, Artemisia argyi 12-18 parts, ginger powder 6-9 parts, tourmaline powder 4-7 parts, and wood vinegar powder 3-5 parts.

[0029] The effects of Angelica pubescens are pungent and bitter, warm and relieve pain, and it is good at removing wind, cold and dampness from the lower body and relieving numbness and pain.

[0030] The effects of mulberry mistletoe are to dispel wind and dampness, tonify the liver and kidneys, and strengthen muscles and bones. When combined with angelica pubescens, it can eliminate pathogens and support the body's resistance, addressing both the symptoms and the root cause.

[0031] The effects of Chuanxiong are to invigorate blood circulation, promote qi circulation, dispel wind and relieve pain. It is a "qi-regulating medicine in the blood" that can promote the circulation of qi and blood to help the medicine reach its full potential.

[0032] The stir-fried Sichuan peppercorns are characterized by their strong hot and intense properties, warming the middle jiao (spleen and stomach), dispelling cold, eliminating dampness, and relieving pain. When applied externally, they can produce a significant spicy and warming sensation.

[0033] The mugwort described here has a pure yang nature, which can warm and unblock the twelve meridians, dispel cold and relieve pain, making it a core material for traditional moxibustion.

[0034] The ginger powder has the effects of being pungent and warm, dispersing cold, and its gingerol components can stimulate the skin and promote local microcirculation and drug penetration.

[0035] The tourmaline is used to continuously release far-infrared rays, which resonate with human tissue to generate heat and achieve a deep physical warming effect.

[0036] The wood vinegar powder has the effects of being weakly acidic and having small molecular properties, which can gently soften the stratum corneum, inhibit bacteria and reduce inflammation, and promote the transdermal absorption of other active ingredients.

[0037] The pungent and hot properties of Sichuan pepper, mugwort, and ginger powder, combined with the physical heat energy of tourmaline, powerfully dispel cold and dampness.

[0038] The combination of the qi-regulating and blood-activating effects of Chuanxiong and the capillary dilation caused by its warming effect significantly improves local blood circulation, achieving the goal of "no pain when there is free flow".

[0039] The Angelica pubescens and Taxillus chinensis, while dispelling wind and dampness, strengthen muscles and bones, improve blood circulation, and work together to relieve pain and repair tissues.

[0040] The wood vinegar powder's penetration-enhancing effect, combined with its warming and blood-activating effects, creates a virtuous cycle, significantly improving the overall bioavailability and onset speed of the formula.

[0041] Preferably, the precautions for using the above-mentioned cold-dispelling and dampness-removing patches include:

[0042] 1) A skin allergy test must be performed before use: Apply a corner of the patch to the inside of the wrist or behind the ear and observe for half an hour. If there is no redness, swelling, itching, papules or other reactions, it can be used normally.

[0043] 2) Strictly differentiate and use according to syndrome differentiation: This product is suitable for "cold-damp syndrome" with symptoms such as pain aggravated by cold and relieved by warmth, local non-redness and heat, pale tongue with white and greasy coating; it is contraindicated for "damp-heat syndrome" or "heat arthralgia" with local redness, swelling, heat and pain;

[0044] 3) Clear contraindications: Do not apply to areas of skin with broken skin, ulcers, acute eczema, or dermatitis; pregnant women, breastfeeding women, infants, and those with known allergies to any of the ingredients are prohibited from use.

[0045] 4) Monitoring during use: The application time should not exceed 24 hours. If persistent and severe burning pain, itching or rash occurs during use, remove the patch immediately and wash with clean water. Seek medical attention if necessary.

[0046] 5) Adjunctive therapy: This product is for external use and cannot replace oral medication. For severe or persistent diseases, comprehensive treatment should be carried out under the guidance of a physician.

[0047] Preferably, in the above-mentioned cold-dispelling and dampness-removing patch, the overall dimensions of the finished patch are 13cm in length and 10cm in width; wherein, the medicated core layer is encapsulated in a circle, the medicated core weighs 3g, has a diameter of 5.5cm, and is located in the central area of ​​the patch.

[0059] The cold-dispelling and dampness-removing patch disclosed in this invention...

[0060] Example 1

[0061] Ingredients: Accurately weigh the following ingredients (by weight): 15 parts Angelica pubescens, 15 parts Taxillus chinensis, 12 parts Ligusticum chuanxiong, 8 parts roasted Sichuan pepper, 15 parts Artemisia argyi, 8 parts ginger powder, 5 parts tourmaline powder (8000 mesh), and 4 parts wood vinegar powder (300 mesh).

[0062] Pretreatment and pulverization: Angelica pubescens, Taxillus chinensis, Ligusticum chuanxiong, roasted Sichuan pepper, and Artemisia argyi were washed and ground separately, then dried at 60℃ until the moisture content was <10%. They were then added to an ultrafine pulverizer along with ginger powder, pulverized, and passed through a 180-mesh sieve to obtain mixed fine powder A.

[0063] Mixing and Drying: Place the fine powder A, tourmaline powder, and wood vinegar powder into a mixer and mix for 45 minutes until completely homogeneous. Transfer the homogeneous powder to a drying tray and place it in a drying oven at 50°C and <30% humidity for 5 hours. The final moisture content is measured to be 7.2%, yielding dried mixed powder B.

[0064] Core making: Using a circular mold and breathable spunlace fabric, dry mixed medicine powder B is quantitatively filled (each patch contains 3g of medicine powder) and heat-pressed into a circular medicine core package with a diameter of 5.5cm.

[0065] Adhesive Coating and Lamination: An acrylic pressure-sensitive adhesive is uniformly coated onto the medical spunlace fabric (substrate) and cured in a 65°C dryer to form an adhesive layer. The drug core pack is then centered and fixed onto the non-adhesive side of the coated spunlace fabric.

[0066] Cutting and Packaging: Cut the laminated material into 13cm x 10cm rectangular patches and cover the adhesive side with release paper. Pack the patches into aluminized bags (13cm x 17cm), vacuum-seal them.

[0067] Beneficial effects

[0068] Compared with existing technologies, the cold-dispelling and dampness-removing patch provided by this invention has the following significant beneficial effects:

[0069] 1. Scientifically designed formula, addressing both the symptoms and root cause: Primarily composed of Angelica pubescens and Artemisia argyi, specifically targeting the elimination of cold and dampness through the patch; Taxillus chinensis tonifies the liver and kidneys to strengthen the body's foundation, Ligusticum chuanxiong invigorates blood and promotes qi circulation to unblock the meridians, and roasted Sichuan pepper enhances the dispelling of cold and pain relief; ginger powder promotes heat and penetration, tourmaline provides a sustained physical heat source, and wood vinegar powder reduces inflammation and promotes penetration; all these are used as adjuvants. The entire formula closely addresses the pathogenesis of "cold and dampness," integrating the elimination of pathogens, strengthening of the body's resistance, unblocking of meridians, and pain relief.

[0070] 2. Multiple warming effects superimposed: It creates a dual heating mode that combines "chemical heat" (the stimulating components of Sichuan pepper, ginger, and mugwort) with "physical heat" (far-infrared rays from tourmaline). Chemical heat takes effect quickly, while physical heat penetrates deeply and lasts longer. The two work together to more effectively dilate local blood vessels, accelerate blood circulation, and fundamentally dispel cold pathogens.

[0071] 3. Significantly promotes transdermal absorption: On the one hand, the warming effect and the blood-activating effect of Ligusticum chuanxiong can significantly increase skin blood flow and pore opening; on the other hand, the weak acidity and small molecule properties of wood vinegar powder can gently alter the barrier function of the stratum corneum. The synergistic effect of these two factors greatly enhances the transdermal absorption rate and amount of active ingredients in traditional Chinese medicine.

[0072] 4. Safe and convenient to use: Made with hypoallergenic medical adhesive and breathable substrate, ensuring comfortable application; all components are natural or recognized safe physical materials, making it highly safe for external use on intact skin. Individually packaged for hygiene, portability, and easy storage, making it ideal for daily family health care and supplementary treatment.

[0073] 5. Long-lasting and stable therapeutic effect: Through process control, the fineness and dryness of the powder are ensured, making it easy for the active ingredients to be released slowly and continuously; the far-infrared emission function of tourmaline is long-lasting, which can provide long-term thermal support for the drug's action, thereby extending the effective action time of a single application.
