Description

Technical Field

[0001] The invention relates to the technical field of ointments and plasters, and in particular to a Chinese medicine plaster for neck, shoulder, waist and leg pain and a preparation method thereof. Background Art

[0002] In today's society, neck, shoulder, waist and leg pain has become an extremely common health problem, seriously affecting people's quality of life and daily activities. With the changes in modern lifestyles, factors such as long-term desk work, long periods of sitting, frequent use of electronic devices and an aging population have caused the incidence of neck, shoulder, waist and leg pain to continue to rise.

[0003] From the perspective of pathogenesis, pain in the neck, shoulders, waist and legs is the result of the combined effects of multiple factors. In the neck, maintaining a bad posture for a long time, such as looking down at a mobile phone or computer for a long time, will cause excessive tension in the neck muscles, changes in the physiological curvature of the cervical spine, and then compress the surrounding nerves and blood vessels, causing neck pain and stiffness, and may also be accompanied by symptoms such as headaches, dizziness, and numbness of the upper limbs. Shoulder pain is often associated with periarthritis of the shoulder, which is mostly caused by degeneration, trauma, and strain of the soft tissue of the shoulder, causing inflammation of the shoulder muscles, tendons, bursae and other tissues, affecting the normal movement of the shoulder joint. For the waist, lumbar muscle strain is one of the common causes. Long-term bending over, standing for a long time, and other bad postures keep the waist muscles in a tense state for a long time, causing fatigue damage; lumbar disc herniation is due to the degeneration and damage of the lumbar disc, which causes the nucleus pulposus of the disc to protrude, compressing the surrounding nerve tissue, causing low back pain, numbness and pain in the lower limbs and other symptoms. Leg pain may be caused by radiating pain from lumbar lesions, or it may be caused by problems in the lower limb joints themselves, such as wear and tear and inflammation of the hip, knee, and ankle joints, causing joint pain and limited movement.

[0004] At present, there are many methods for treating neck, shoulder, waist and leg pain. In terms of drug treatment, oral drugs include non-steroidal anti-inflammatory drugs, muscle relaxants, analgesics, etc., but these drugs may have side effects such as gastrointestinal irritation and liver and kidney damage. External drugs such as some analgesic creams, latex agents, etc., although easy to use, may be insufficient in the depth and persistence of pain relief. Physical therapy methods, such as massage, massage, acupuncture, etc., although they can relieve pain and improve local blood circulation to a certain extent, require professional operation, and the treatment cycle is long, and patients need to spend more time and energy. Surgical treatment has the problems of high risk, high cost, long postoperative recovery time, and not all patients are suitable for surgery. Therefore, it is of great practical significance to develop a product for treating neck, shoulder, waist and leg pain that is convenient to use, has significant efficacy and is highly safe. The neck, shoulder, waist and leg pain patch of the present invention is developed based on such background, and is intended to provide a new and effective treatment option for the majority of neck, shoulder, waist and leg pain patients. Summary of the invention

[0005] The invention aims to solve the shortcomings of the prior art and proposes a Chinese medicine patch for neck, shoulder, waist and leg pain, the medicine composition of which includes white mustard seeds, kudzu root, sappan wood, clematis root, asarum, notopterygium root and ligusticum chuanxiong.

[0007] A preparation method of a Chinese medicine plaster for neck, shoulder, waist and leg pain, Step 1, selection of medicinal materials: According to the formula ratio, select high-quality white mustard seeds, kudzu root, rhizoma sappani, radix clematis, asarum, notopterygium wilfordii, and rhizoma chuanxiong; when selecting medicinal materials, ensure that the medicinal materials are free of mold and insect infestation, and meet the medicinal standards; Step 2, pretreatment of medicinal materials: preliminarily clean the selected medicinal materials to remove impurities. For some rhizomes, wash and dry them. For medicinal materials with fluff or easy-to-shed skin, handle them with care to avoid loss of active ingredients or introduction of impurities during the processing; Step 3, grinding medicinal materials: using grinding equipment to put the pre-treated medicinal materials into a grinder for grinding; grinding until it meets the requirements for paste production, so that the paste produced later is fine and uniform, which is conducive to the release of drug ingredients and skin absorption; Step 4, paste preparation: Mix the screened powders in a specific ratio. You can use a stirring device; set the appropriate stirring speed and time to fully mix the powders to ensure that the proportion of the drug ingredients in each part of the paste is accurate and consistent; prepare an appropriate amount of matrix material, heat the matrix material to an appropriate temperature to melt it into a liquid state, and then slowly add the mixed powders to the melted matrix while stirring continuously to fully blend the powders and the matrix to form a uniform paste; Step 5, spreading: After the temperature of the paste drops slightly, use a plaster spreading device to evenly spread the paste on a breathable and flexible patch material to make a pain patch base.

[0008] Step 6, stick the release paper on the base of the pain patch to protect the stickiness of the plaster. Tear it off from the bottom of the plaster when using it.

[0009] Preferably, after grinding, the powder is screened through a sieve to remove coarse particles that are not fully ground, ensuring that the fineness of all powders reaches 80-100 mesh.

[0010] Preferably, the matrix material is heated to a temperature of 160-170°C.

[0011] Preferably, the matrix material can be selected from substances such as vaseline and lanolin which have good adhesion and moisturizing properties.

[0013] Preferably, the thickness of the paste should be well controlled during application. Generally, the thickness of each paste is 0.6 mm to ensure that the drug content is accurate and the paste is not easy to fall off or flow during application.

[0014] Preferably, in step S6, before the release paper is pasted, a steel ball is placed on the base of the pain patch to facilitate pressing and finding acupoints, and the steel ball is also pasted between the release paper and the base of the pain patch.

[0015] The specific pharmacology of the above technical scheme is that the prescription is mainly composed of drugs with strong pungent, salty, warm and dispersing power. Pueraria root is pungent and dispersing, penetrating the surface, and is good at relieving the blockage of meridian qi and relieving the strong pain in the neck and back. White mustard and asarum are pungent, dispersing, warm and unblocking in nature and flavor, and are suitable for Yin sores caused by cold stagnation and phlegm stagnation, slow swelling without head, soreness without heat, and numbness of limbs and joint pain caused by damp phlegm flowing into the meridians. Qianghuo and Chuanxiong can both be pungent, dispersing, warm and unblocking, and can not only promote blood circulation and remove blood stasis to dredge the meridians, but also disperse the wind, cold and dampness in the surface, and can promote qi and resolve stagnation to relieve pain; they can be used for the surface symptoms of wind, cold and dampness, chest and flank pain, heart and abdomen pain caused by blood stasis and qi stagnation, and soreness and pain in limbs caused by injuries.

[0023] Figure 1 The invention discloses a preparation process of a Chinese medicine plaster for neck, shoulder, waist and leg pains. DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Referring to the figures, this embodiment provides a Chinese medicine patch for neck, shoulder, waist and leg pain, the drug composition of which includes white mustard seeds, kudzu root, rhizoma celadonis, radix clematis, asarum, notopterygium wilfordii and rhizoma ligusticum.

[0026] Furthermore, the white mustard seeds are 25g, the kudzu root is 10g, the rhizome of sappan is 7g, the radix clematis is 10g, the asarum is 15g, the notopterygium is 17g, and the rhizome of ligusticum is 15g.

[0027] A preparation method of a Chinese medicine plaster for neck, shoulder, waist and leg pain, Step 1, selection of medicinal materials: According to the formula ratio, select high-quality white mustard seeds, kudzu root, rhizoma sappani, radix clematis, asarum, notopterygium wilfordii, and rhizoma chuanxiong; when selecting medicinal materials, ensure that the medicinal materials are free of mold and insect infestation, and meet the medicinal standards; Step 2, pretreatment of medicinal materials: preliminarily clean the selected medicinal materials to remove impurities, such as dirt and dust. For some rhizomes, wash and dry them. For medicinal materials with fluff or easy-to-shed skin, handle them with care, such as Asarum, to avoid loss of active ingredients or introduction of impurities during the processing; Step 3, grinding of medicinal materials: use grinding equipment to put the pretreated medicinal materials into the grinder for grinding; grind until they meet the requirements of paste production, so that the subsequent paste is delicate and uniform, which is conducive to the release of drug ingredients and absorption by the skin; in this grinding process, the grinding speed and time must be controlled to ensure that the medicinal materials can be ground into fine powder, while avoiding overheating of the medicinal materials due to excessive grinding and affecting the efficacy. For example, for harder textures of Sophora japonica and Clematis chinensis, the grinding time can be appropriately extended, but attention must be paid to monitoring the temperature. For medicinal materials with relatively high oil content such as Chuanxiong, care must be taken to prevent the heat generated by grinding from causing the oil component to seep out and affecting the uniformity of the powder; Step 4, paste preparation: Mix the screened powders in a specific ratio. You can use a stirring device; set the appropriate stirring speed and time to fully mix the powders to ensure that the proportion of the drug ingredients in each part of the paste is accurate and consistent; prepare an appropriate amount of matrix material, heat the matrix material to an appropriate temperature to melt it into a liquid state, and then slowly add the mixed powders to the melted matrix while stirring continuously to fully blend the powders and the matrix to form a uniform paste; Step 5, spreading: After the temperature of the paste drops slightly, use a plaster spreading device to evenly spread the paste on a breathable and flexible patch material to make a pain patch base.

[0028] Step 6, stick the release paper on the base of the pain patch to protect the stickiness of the plaster. Tear it off from the bottom of the plaster when using it.

[0029] Furthermore, after grinding, the powder is screened through a sieve to remove coarse particles that are not fully ground, ensuring that the fineness of all powders reaches 80-100 mesh.

[0030] Furthermore, the matrix material is heated to a temperature of 160-170°C.

[0031] Furthermore, the matrix material can be selected from substances having good adhesion and moisturizing properties such as vaseline and lanolin.

[0032] Furthermore, the coating equipment is an automatic plaster coating machine, and the patch material is a non-woven fabric or a medical adhesive tape.

[0033] Furthermore, the thickness of the paste should be well controlled during application. Generally, the thickness of each paste is 0.6 mm, ensuring that the drug content is accurate and that it is not easy to fall off or flow during application.

[0034] Furthermore, in step 6, before the release paper is pasted, a steel ball is placed on the base of the pain patch to facilitate pressing and finding acupuncture points, and the steel ball is also pasted between the release paper and the base of the pain patch. When in use, the Chinese medicine patch with the steel ball is pasted on the acupuncture points of the human body, and pressure stimulation can be exerted through external force to clean the corresponding acupuncture points. The corresponding acupuncture points are rubbed with the thumbs in turn, each for 1 to 2 minutes, from small to large, and from light to heavy, to explore sensitive points.

[0035] The specific use steps of the above embodiment include the following steps: S1, the patient cleans the skin of the painful area; S2, tear open the pain patch package and stick it on the painful area, making sure it is firmly applied; S3, according to the dosage and usage regulations, apply one patch a day, each patch should be applied for about 8 hours, use according to the course of treatment, and observe the taboos and precautions during the application period.
