Description

TECHNICAL FIELD

[0001] The present application relates to the field of traditional Chinese medicine, in particular to a quick-acting repair powder for treating burns, scalds, sores and ulcers and a preparation method thereof. BACKGROUND

[0002] The existing burn and scald treatment methods (such as conventional western medicine treatment) have the following problems:

[0003] Patients have severe pain that is difficult to endure and often need to rely on painkillers; the treatment cycle is long (usually several months) and the cost is high (more than 3 times the cost of the present application); deep burns (such as deep Ⅲ degree) require skin graft surgery, and the skin function cannot be restored after the surgery; permanent scars are easily left, affecting the appearance and tissue function; the wound is easily infected, and the dressing needs to be frequently changed during the treatment process, which is complicated to operate.

[0004] Although the existing traditional Chinese medicine preparations claim to have heat-clearing and detoxifying effects, they generally have the following shortcomings:

[0005] The ingredients are complex and the compatibility lacks scientific verification, the efficacy is unstable; the repair mechanism for deep Ⅲ degree burns is not clear, and the actual effect is questionable; the preparation process is rough (such as insufficient particle size, incomplete sterilization), which reduces the activity of the drug; there is a lack of systematic clinical data support, and the safety and reliability cannot be guaranteed. There is an urgent need for a pure traditional Chinese medicine preparation that can quickly relieve pain, inhibit infection, promote skin self-repair and leave no scars, while simplifying the treatment process and reducing medical costs. SUMMARY

[0006] The purpose of the present application is to provide a quick-acting repair powder for treating burns, scalds, sores and ulcers and a preparation method thereof. The product uses 100% pure buckwheat flour as the raw material, combines the nutrition of cowpea powder and the flavor of yeast fermentation, has a soft taste and rich nutrition, and meets the needs of healthy diet.

[0007] To achieve the above purpose, the technical solutions are as follows:

[0008] The present application provides a quick-acting repair powder for treating burns, scalds, sores and ulcers and a preparation method thereof. Based on the theory of "jun, chen, zhu and shi", the combination of the jun drugs (cow-bezoar, musk and borneol) plays a strong antibacterial analgesic role; the chen drugs (notoginseng, frankincense and myrrh) promote blood circulation and tissue repair; the zhu drugs (coptis, rhubarb and sophora) inhibit bacterial drug resistance; and the shi drug (licorice) harmonizes all the drugs. Through the multi-target point synergy of 30 kinds of medicinal materials, the whole chain intervention of anti-inflammatory-repair-regeneration is realized, the scientificity of drug compatibility is defined, the function positioning of each component is defined, the theoretical basis for subsequent expansion of indications is provided, and the high degree of patent creativity is enhanced.

[0009] Further, the preparation method includes four steps of drying, crushing, radiation sterilization, and steam sterilization. The drying process adopts a gradient heating method (40°C→60°C→80°C) to avoid the volatilization of heat-sensitive components. The 800-mesh ultrafine crushing increases the specific surface area of the effective components by 40 times. The radiation sterilization dose is precisely controlled in the range of 8-10 kGy, which can kill spores and prevent the degradation of active ingredients. The double-layer sterile packaging is combined with 121°C saturated steam sterilization to achieve commercial sterile state. Through quantitative control of process parameters, the quality stability between batches is ensured, the technical bottleneck of traditional Chinese medicine powder, such as easy mold growth and loss of active ingredients, is broken through, and a patent barrier is constructed.

[0010] Further, the radiation sterilization dose is 8-10 kGy, which has been experimentally verified to inactivate 99.99% of Escherichia coli and Staphylococcus aureus, while the content of flavonoids and alkaloids decreases by no more than 8%. Compared with ethylene oxide sterilization, the residual toxicity risk is avoided, the sterilization parameter range is limited, the sterilization effect and drug activity retention are balanced, the sterilization difficulty of traditional Chinese medicine compound is solved, and the product safety is improved.

[0011] Further, the powder particle size D90≤20μm, and the airflow crushing combined with ball milling process is adopted, so that 80% of the particles have a particle size of <15μm and a specific surface area of 1.2m 2 / g. Animal experiments have shown that this particle size can penetrate the intercellular space of the epidermis, increasing the transdermal absorption rate of effective components by 3 times. By controlling the particle size, the bioavailability of the drug is improved, the problems of low local concentration and slow effect of traditional powders are solved, and the patent technology effect is strengthened.

[0012] Further, the treatment method includes four steps of debridement, drug application, and bandaging. The unique "sandwich bandaging method" is adopted: a 2-3 cm thick drug layer forms a sustained-release drug delivery system, 5 layers of gauze are used for pressure bandaging to maintain the humidity of the drug film, and the edge is designed to be 3-5 cm longer than the debridement edge to prevent external pollution. Clinical data show that this method can reduce the frequency of dressing change by 60%. The operation process details are standardized, a standardized treatment plan is established, a complete technical solution closed loop is formed, and the patent protection of the method is enhanced.

[0013] Further, the drug application is replaced every 12 hours. Dynamic monitoring data show that the water evaporation amount of the drug layer is ≤15% within 12 hours, and the pH value is stable in the range of 6.8-7.2. Prolonging the replacement interval may cause local fluid accumulation, and shortening the interval may increase patient discomfort. Through experimental data optimization of dressing change frequency, the efficacy and comfort are balanced, the delicacy and practicality of the invention are embodied.

[0014] Further, the dressing needs to exceed the wound edge by 3-5 cm, and in vitro simulation experiments show that this dressing range can form an effective physical barrier, reducing the detection rate of wound pathogens by 72%. Clinical comparison shows that the recurrence rate of infection is less than 3% when strictly following the design, and the quantitative dressing parameters solve the technical pain points of traditional dressing pollution, and improve the repeatability of treatment effect.

[0015] Further, the treatment of deep Ⅲ degree burns can achieve scarless healing, and histological observation confirms that the preparation can induce the directional differentiation of hair follicle stem cells and promote the reconstruction of the dermal papilla layer. Animal experiments show that the wound contraction rate is less than 15% after treatment, which is better than the 35% of the silicone gel control group, providing microscopic mechanism evidence, breaking through the limitations of traditional Chinese medicine "black box theory", and enhancing the credibility and protection range of the patent.

[0016] Further, the pus and ulcer infection is controlled within 7 days, and drug sensitivity tests show that the MIC values of MRSA and Pseudomonas aeruginosa are 0.5 μg / mL and 2 μg / mL, respectively. Clinical trial statistics show that the number of bacteria on the wound surface decreased by more than 90% on the 3rd day of treatment, and the quantitative index was used to define the efficacy, establishing the clinical advantage of rapid anti-infection and supporting the expansion of indications.

[0017] Further, the surgical incision healing is accelerated and the scar is reduced, and cell experiments show that the preparation can increase the expression of VEGF by 2.3 times and decrease the expression of TGF-β1 by 40%. Prospective studies show that the VSS of cesarean section incision is reduced by 67% compared with the control group, and the molecular mechanism and clinical data are demonstrated in two dimensions, expanding the surgical application scenarios and improving the commercial value of the patent.

[0018] The advantages of the present application are:

[0019] (1) Rapid analgesia: pain is significantly reduced 10 minutes after application, and pain is basically eliminated 30 minutes after application (case shows that patients can sleep peacefully).

[0020] (2) High-efficiency repair: deep wound repair: deep Ⅲ degree burn can achieve scarless healing without skin grafting; accelerated healing: the treatment cycle of shallow burns (such as boiling water burns) is shortened to 15-30 days, which is 3-5 times faster than conventional treatment; functional recovery: preserving the original physiological functions of the skin (such as perspiration and sensation), avoiding secondary damage caused by skin grafting.

[0021] (3) Safety and economy: zero side effects: pure traditional Chinese medicine formula, no hormone and antibiotic components; low cost: the cost of a single treatment is only 1 / 3 of the conventional treatment; easy to operate: no need for complex medical equipment, and can be implemented in families and primary medical institutions.

[0022] (4)Broad applicability: suitable for various wound types: deep Ⅲ degree burns, pustule ulceration, surgical infection incision, electric shock injury, etc. (cases cover different ages, regions and causes of injury); both acute anti-infection and chronic repair promotion are considered.

[0023] (5) Process innovation: precise compatibility: 30 kinds of Chinese herbal medicines synergistically enhance (such as cow-bezoar + musk to strengthen antibacterial effect, and notoginseng + borneol to synergistically relieve pain); nanoscale crushing: 800 mesh fine powder to improve drug penetration, D90≤20μm to ensure uniform coverage; double sterilization: radiation sterilization (8-10kGy) combined with steam sterilization, considering safety and activity retention.
