Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine, and in particular to a formula and a preparation process of a Sanfu plaster. Background Art

[0002] Patches have a long history of use both at home and abroad. According to records, the ancient Egyptians and Babylonians used ointments made from plant, animal or mineral extracts. Ancient China also has a history of using natural herbal ingredients as medicinal plasters.

[0003] Among all the topical analgesics in my country, patches are the most commonly used type, accounting for more than 80% of the market share. According to a research report by the China Research Institute of Industry, the plaster patch market is growing rapidly worldwide. In 2022, the global market will be $9.12 billion, a year-on-year increase of 4.5%. At the same time, the size of the Chinese market will increase by 8.8% year-on-year, with a market share of about 11.44 billion. The market is showing a rapid and steady growth trend, especially the domestic market growth trend is more obvious, especially with the continuous emergence of new varieties such as functional patches and smart patches, making the market prospects broader. Correspondingly, the market share of traditional Chinese medicine patches has shown a significant growth trend, which can maintain an annual growth rate of about 10%.

[0004] There are various Sanfutie products on the market, and the problems of these products are as follows: the particle size of the medicinal materials is not enough, which can easily irritate the skin when used, and the efficacy is poor. Using Chinese medicine concentrate as the main ingredient cannot control the efficacy well, and the product is prone to breed bacteria and cause secondary infection. The ingredients are relatively single and cannot cope with various ranges well. Precious Chinese herbal medicines are added at will, and the actual efficacy does not achieve the expected effect. The use of some raw materials is harmful to the human body. As a patch that needs to be used multiple times, this situation may cause adverse reactions in users. The ointment matrix is ​​poorly selected, and it is easy to dry and crack after long-term storage. Summary of the invention

[0005] The purpose of the present invention is to provide a formula and preparation process of Sanfu plaster, aiming to solve the problem that the existing Sanfu plaster ointment base is poor and prone to cracking after long-term storage.

[0009] Adding glycerin, propylene glycol, sodium carboxymethylcellulose, the vaseline base, alcohol and the sodium carboxymethylcellulose solution to the first mixed raw material in sequence and stirring them respectively to obtain a semi-finished product;

[0010] The semi-finished product is placed in a mold for shaping, a stainless steel ball is placed in the middle, and then a medical non-woven fabric is placed therein to obtain a Sanfu patch.

[0011] Among them, in "preparing 1% sodium carboxymethyl cellulose solution, vaseline matrix, mineral powder, Chinese medicinal material powder and ginger juice", the 1% sodium carboxymethyl cellulose solution is prepared by soaking 600 parts of water in 6 parts of sodium carboxymethyl cellulose; the vaseline matrix is ​​prepared by heating and melting vaseline and yellow beeswax and then stirring; the mineral powder is prepared by crushing and sieving sulfate ore; the Chinese medicinal material powder is prepared by respectively crushing and sieving white mustard, vinegar Corydalis yanhusuo, vinegar kansui, asarum and cinnamon; the ginger juice is prepared by squeezing fresh ginger.

[0012] Among them, in “adding glycerol, propylene glycol, sodium carboxymethyl cellulose, the vaseline base, alcohol and the sodium carboxymethyl cellulose solution to the first mixed raw material in sequence and stirring them respectively to obtain a semi-finished product”, the stirring time after adding the glycerol is 10 min; the stirring time after adding the propylene glycol is 10 min; the stirring time after adding the sodium carboxymethyl cellulose is 10 min; the stirring time after adding the vaseline base is 10 min; the stirring time after adding the alcohol is 10 min; the stirring time after adding the sodium carboxymethyl cellulose solution is 30 min.

[0013] Among them, in "the stirring time after adding the vaseline base is 10 minutes", the temperature maintained when adding the vaseline and stirring is 50°C.

[0014] In the second aspect, a formula for a Sanfu plaster is used in the preparation process of the Sanfu plaster described in the first aspect, comprising 9600-10800 parts of sulfate ore powder, 380-494 parts of white mustard powder, 1050-1140 parts of vinegar Corydalis powder, 500-570 parts of vinegar Kansui powder, 480-570 parts of asarum powder, 240-286 parts of cinnamon powder, 260-286 parts of ginger juice, 900-1050 parts of glycerin, 750-900 parts of propylene glycol, 18 parts of vanillyl butyl ether, 36 parts of water-soluble azone, 96 parts of sodium carboxymethyl cellulose, 816 parts of vaseline, 84 parts of yellow beeswax, 600 parts of water, and 150 parts of 95% alcohol.

[0015] The preparation process of a Sanfu plaster of the present invention comprises the following steps: preparing a 1% sodium carboxymethylcellulose solution, a vaseline matrix, ore powder, Chinese medicinal material powder and ginger juice; adding the Chinese medicinal material powder, the ginger juice and the sulfate ore powder into a stirring tank and stirring to obtain a first mixed raw material; adding glycerin, propylene glycol, sodium carboxymethylcellulose, the vaseline matrix, alcohol and the sodium carboxymethylcellulose solution into the first mixed raw material in sequence and stirring them respectively to obtain a semi-finished product; placing the semi-finished product into a mold for shaping, placing a stainless steel ball in the middle, and then placing a medical non-woven fabric to obtain the Sanfu plaster.

[0091] Beneficial effects:

[0092] 1. The present invention is based on the traditional Sanfutie and adds the sulphate ore powder which is unique to Zhuang medicine, so as to achieve the effect of strengthening the physical fitness and harmonizing yin and yang.

[0093] 2. The present invention adds water-soluble azone and vanillyl butyl ether as auxiliary materials, which can effectively make the application site warm, promote blood flow and skin absorption of drugs, and improve the product efficacy.

[0094] 3. The invention adds ginger juice, which has a good effect of warming the middle and regulating qi, can well promote drug absorption, effectively promote the rise of yang qi in the patient's body, and achieve a therapeutic effect.

[0095] Fourth, the addition of 95% ethanol in the present invention can effectively prevent the growth of microorganisms and extend the shelf life of the product to a certain extent.

[0096] The above disclosure is only a preferred embodiment of the formula and preparation process of the Sanfu plaster of the present invention. Of course, it cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention are still within the scope of the invention.
