Description

Technical Field

[0001] The invention relates to the technical field, specifically to a lumbar vertebrae external-use plaster with the function of promoting blood circulation and unblocking meridians and a preparation process thereof. Background Art

[0002] The present invention relates to the technical field of lumbar spine diseases (such as lumbar disc herniation, lumbar muscle strain, chronic low back pain, etc.) with a high incidence rate in the population, seriously affecting the quality of life and working ability of patients. Current clinical treatments are mainly oral analgesics, physical rehabilitation and surgery, but there are problems such as limited efficacy, obvious side effects or poor patient compliance. Therefore, safe, effective and convenient topical treatments have attracted widespread attention.

[0003] As a treatment method that combines traditional Chinese medicine with modern formulation technology, Chinese herbal topical plasters have the advantages of transdermal absorption, concentrated site of action, minimal adverse reactions, and ease of use for patients. In the existing technology, common lumbar topical plasters often use a single or small amount of Chinese herbal ingredients, or are mainly composed of over-the-counter drugs. Although they can temporarily relieve pain, their efficacy in promoting blood circulation, reducing swelling and relieving pain, improving local microcirculation, and promoting tissue repair is less than ideal. At the same time, some products have poor matrix adhesion, uneven distribution of ingredients, and poor ventilation, which can easily cause skin irritation and allergies, affecting patients' long-term and standardized medication use.

[0004] The existing technical solutions have the technical problems of single formula and matrix-free patch, which leads to loose adhesion and poor efficacy. Invention content

[0005] In response to the deficiencies in the prior art, the present invention provides a lumbar external-use plaster with the function of promoting blood circulation and unblocking meridians and its preparation process, which solves the technical problems of the prior art solutions such as single formula and lack of a matrix, resulting in loose adhesion and poor efficacy.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a lumbar vertebrae external plaster with the function of promoting blood circulation and unblocking meridians, comprising a patch layer, a drug layer and a coating layer arranged in sequence, wherein the patch layer is a non-woven fabric or a polyurethane film, and the drug layer comprises the following Chinese herbal extracts and excipients in parts by weight: 5-15 parts of Atractylodes lancea, 3-10 parts of Chuanxiong, 2-8 parts of Carthamus tinctorius, 3-8 parts of Angelica sinensis, 1-5 parts of frankincense, 1-5 parts of myrrh, 2-8 parts of Panax notoginseng, 0.5-2 parts of menthol, 10- The invention discloses a paste comprising the following steps: the paste comprises: a paste comprising: a patch layer, ...

[0045] In parts by weight, the components of the drug layer in the lumbar vertebrae external plaster are preferably:

[0046] 10 parts of Atractylodes lancea, 6 parts of Chuanxiong, 5 parts of Carthamus tinctorius, 5 parts of Angelica sinensis, 3 parts of Frankincense, 3 parts of Myrrh, 5 parts of Panax notoginseng, 1 part of Menthol, 20 parts of Honey, 35 parts of Vaseline, 6 parts of auxiliary agents (2 parts of Sheep Oil, 1 part of Borneol, 1 part of Camphor, 2 parts of Zinc Oxide), the patch layer has a gram weight of 50g / m 2 Highly breathable medical non-woven fabric, the coating layer is ethylene-vinyl acetate copolymer film and is covered with a silicone oil paper protective layer.

[0047] Take the above-mentioned formula amounts of Atractylodes lancea, Chuanxiong rhizome, safflower, Chinese angelica, frankincense, myrrh, and Panax notoginseng, clean and remove impurities, and dry at room temperature. Grind the safflower into a fine powder after drying in the shade. Slice the remaining herbs and pulverize them into 100 mesh fine powders. Grind the frankincense and myrrh directly into a fine powder for later use.

[0048] Mix all the Chinese medicinal powders in proportion and thoroughly mix them. Place the mixed powders in a vacuum drying oven and dry them at 60°C for 6 hours to control the moisture content to ≤8%. Cool them for later use.

[0049] Weigh honey and vaseline, place in a water bath (about 60°C), heat and stir until the mixture is fully integrated and fluid. Slowly pour the pre-mixed Chinese medicine powder into the ointment base in batches, stirring at low speed with a blender until it is initially mixed into an ointment.

[0050] Then add menthol (dissolved in a small amount of ethanol in advance), mutton fat, borneol, camphor, and zinc oxide, and stir at variable speed for 30 minutes to ensure that the medicine is evenly distributed and the paste is fine without obvious particles.

[0051] Stop heating and cool the ointment to room temperature. Use a high-precision scraper device to evenly apply the ointment on the non-woven fabric patch layer, and control the thickness to 1.2mm. Place the coated ointment in a clean and ventilated environment to cool naturally for 30 minutes, or cool and solidify in a refrigerated environment at 4°C. Cover the surface of the ointment with an ethylene-vinyl acetate copolymer film and a protective layer of silicone oil paper to ensure the hygiene and easy peeling of the ointment during storage and use. After cooling and shaping, cut according to specifications (such as 7cm×10cm per piece), package and seal individually to obtain the finished product.

[0052] For local application to treat lumbar conditions such as lumbar disc herniation, chronic low back pain, and lumbar muscle strain. Remove the protective layer and apply directly to the affected area. Change the patch daily for a course of 7-14 days. It effectively relieves lower back pain, improves local blood circulation, and promotes recovery.

[0053] The plaster obtained by the above preparation method has good adhesion and is not easy to fall off. The drug ingredients are evenly distributed and the transdermal absorption effect is ideal. It is highly safe for external use, durable in storage and resistant to deterioration. It can significantly relieve discomfort such as waist pain and swelling, and has obvious effects of promoting blood circulation, removing blood stasis, unblocking meridians and relieving pain, and provides good user experience.

[0054] If personalized adjustments are required, the ratio of Chinese medicine and ointment base can be appropriately adjusted according to different symptoms, but the overall process flow and key parameters remain unchanged to ensure the stability of product performance and efficacy.
