Description

Technical Field

[0001] This invention relates to a traditional Chinese medicine external application pack, and more particularly to a traditional Chinese medicine external application pack for the prevention and treatment of fat liquefaction in surgical incisions. Background Technology

[0002] With the continuous improvement of people's living standards, obesity is showing a rapid growth trend and becoming prevalent across all age groups. High-risk factors for fat liquefaction include both patient-related factors and medical-related factors. Patient-related factors are uncontrollable, such as obesity, diabetes, and hypoalbuminemia; medical-related factors are relatively controllable. Therefore, obesity and diabetes are inextricably linked to the occurrence of fat liquefaction.

[0003] In nearly 30 years of clinical practice, I have observed a growing number of patients with high-risk factors for obesity and diabetes who require surgery, posing a greater challenge to my clinical work. The incidence of surgical incision fat liquefaction is increasing, commonly occurring 5 to 7 days post-surgery. Retrospective analysis of fat liquefaction cases reveals that the majority occur in patients with high-risk factors for fat liquefaction. While the surgery is successfully completed, wound healing becomes the biggest post-operative hurdle, highlighting the urgent need for an effective drug to prevent and treat fat liquefaction.

[0004] There are very few existing traditional Chinese medicine liquids or ointments, such as Kangfuxin Liquid and Compound Phellodendron Amurense Ointment (in plastic bottles), as well as a gel (in bags) with epidermal growth factor as the main ingredient. Its primary purpose is to promote granulation tissue growth and wound healing, but clinical efficacy reports vary. At the same time, there is a lack of topical medications for the prevention and treatment of lipolysis, and finished powdered external application packs containing pure traditional Chinese medicine ingredients are even more scarce.

[0005] For over 20 years, I have used self-made gauze bags or non-woven bags to wrap traditional Chinese medicine powder and apply it externally to abdominal incisions in nearly 1,000 patients to prevent and treat fat liquefaction problems in surgical incisions in patients with high-risk factors. The success rate is approximately 95%, and the clinical results are very satisfactory. However, this self-made external medication requires the patient's family to purchase the traditional Chinese medicine, grind it into powder, and when changing the dressing, the clinician needs to put the powder into a gauze bag or non-woven bag. The powder is prone to spillage during bagging, the non-woven bags are not very clean, and the gauze bags need to be sewn by the doctor. The entire process is cumbersome and has many drawbacks. Summary of the Invention

[0006] The present invention aims to provide a traditional Chinese medicine external application pack for the prevention and treatment of surgical incision fat liquefaction, in order to solve the current problem of the lack of traditional Chinese medicine external application packs for the treatment and prevention of surgical incision fat liquefaction.

[0007] To achieve the above objectives, the specific plan is as follows:

[0008] A traditional Chinese medicine external application pack for the prevention and treatment of surgical incision fat liquefaction includes a bag body and adhesive edges. The bag body includes a support layer and a breathable layer. The breathable layer has several air vents, and the support layer has adhesive edges around its perimeter. The breathable layer is fixed to the support layer by pressing together with the sealing edges, forming a medicine-filling cavity. The medicine-filling cavity is filled with a mixture of traditional Chinese medicine powder. The mixture of traditional Chinese medicine powder includes 2 parts by weight of raw rhubarb and 1 part by weight of Glauber's salt.

[0009] Furthermore, it also includes a Class A external dressing pack measuring 15cm in length and 6cm in width, and a Class B external dressing pack measuring 20cm in length and 6cm in width.

[0010] Furthermore, the support layer is made of medical-grade polyester fiber material; the breathable layer is made of 50 g / m² non-woven fabric; the adhesive edge is medical pressure-sensitive adhesive with a width of 0.5 cm, and a release paper is covered on the outside of the pressure-sensitive adhesive, with the edge of the release paper extending 0.5 cm beyond the pressure-sensitive adhesive.

[0011] In summary, the present invention has the following advantages over the prior art:

[0012] (1) Existing Chinese herbal liquids or ointments on the market are mainly aimed at promoting the formation of granulation tissue in surgical incisions. However, there are no clear reports on their effects on preventing and treating surgical incision fat liquefaction. Based on classic prescriptions and years of clinical experience, a Chinese herbal external application pack for the prevention and treatment of surgical incision fat liquefaction has been invented. This pack provides a preventive and therapeutic effect on fat liquefaction in patients with high-risk factors for fat liquefaction after surgery, which can reduce the incidence of fat liquefaction, reduce the occurrence of surgical complications, and alleviate the patient's pain.

[0013] (2) In my clinical work over the past 20 years, I have used self-made gauze bags or non-woven bags to wrap Chinese medicine powder. This requires patients' families to purchase the Chinese medicine, grind it into powder, and when changing dressings, clinicians need to put the Chinese medicine powder into gauze bags or non-woven bags. The Chinese medicine powder is easy to spill when filling the bags, the non-woven bags are not clean, and the gauze bags need to be sewn by doctors. The operation is cumbersome and the whole process has many drawbacks. Chinese medicine packs can be applied to the surface of surgical incisions. They are easy to use. Just open the packaging and place it directly on the surface of the surgical incision. They are clean and hygienic, and improve the quality and efficiency of medical care.

[0014] (3) Surgical incisions include transverse incisions, longitudinal incisions and oblique incisions. Therefore, designing two types of Chinese medicine external application packs, A and B, is suitable for clinical use.

[0015] (4) The external application material facilitates the penetration of Chinese medicine powder into the skin, thereby improving the efficacy and comfort of the medicine.

[0016] (5) The packaging quantity is economical and practical: Based on clinical experience, each cardboard box contains 3 Chinese medicine external application packs, which are suitable for use every other day until the sutures are removed and the patient is discharged.

[0017] (6) To prevent the Chinese medicine powder from deteriorating, each Chinese medicine bag is vacuum-packed with a transparent bag attached, and a desiccant packet is placed inside each cardboard box. Attached Figure Description

[0027] Based on classic prescriptions and combined with years of clinical experience, we provide a traditional Chinese medicine external application pack for the prevention and treatment of surgical incision fat liquefaction. The efficacy of the raw materials used is as follows:

[0028] Raw rhubarb, also known as Huang Liang, has the effects of purging accumulations, clearing heat and purging fire, cooling blood and detoxifying. It is often used to treat heat toxicity, break up accumulations, and promote blood circulation. It is used to treat constipation due to excess heat, delirium, food stagnation and abdominal distension, early stage of dysentery, tenesmus, amenorrhea due to blood stasis, abdominal masses, epidemic febrile diseases, sudden red and painful eyes, hematemesis, epistaxis, jaundice, edema, urinary tract infections, carbuncles, boils, and burns.

[0029] Glauber's salt, also known as mirabilite, has the effects of purging and relieving constipation, clearing heat and reducing swelling, and softening and dispersing nodules. It is often used to treat symptoms such as heat accumulation, abdominal distension and constipation, phlegm accumulation, red mouth and eye obstruction, erysipelas, and carbuncles.

[0030] Although the combination of these two herbs originates from the "Major Purgative Decoction" in the *Treatise on Cold Damage*, in modern clinical practice it has transcended the original formula and become an independent and extremely commonly used combination. Its core lies in the synergistic effect of "purgation," especially in surgery and external treatments. Usage: Grind the two herbs into powder, mix them in a 2:1 ratio, wrap in gauze, and apply externally to the affected area. Mechanism: Effectively reduces edema and inflammation around the incision site, improves local circulation, reduces the incidence of fat liquefaction, or promotes the healing of incisions with fat liquefaction. Therefore, this classic Chinese medicine formula is applied to clinical practice.

[0031] See Figures 1-3As shown, this invention provides a traditional Chinese medicine external application pack for the prevention and treatment of surgical incision fat liquefaction, hereinafter referred to as the external application pack. It includes a bag body and adhesive edges. The bag body consists of a support layer and a breathable layer. The breathable layer has several breathable holes. The support layer has adhesive edges around its perimeter, which can adhere to the skin surface to fix the external application pack. The breathable layer is fixed to the support layer by pressing together with the sealing edge, forming a medicine-filling cavity. The medicine-filling cavity is filled with the aforementioned traditional Chinese medicine mixed powder, thus ultimately forming the traditional Chinese medicine external application pack for the prevention and treatment of surgical incision fat liquefaction as described in this invention.

[0032] Example 1: Preparation of Traditional Chinese Medicine External Application Pack

[0033] I. Selection and Processing of Raw Materials

[0034] Raw material selection: Raw rhubarb and Glauber's salt are selected strictly in accordance with pharmaceutical standards. Raw rhubarb must be of high quality, with a yellowish-brown cross-section, firm texture, and a fragrant aroma, ensuring that its effective ingredient content meets standards. Glauber's salt should be selected as a colorless, transparent or off-white crystalline powder, free of impurities and odors, to avoid affecting efficacy due to raw material quality issues.

[0035] Pulverization: Selected raw rhubarb and Glauber's salt are separately pulverized in an ultra-fine pulverizer. The resulting powder particles are 100-120 mesh.

[0036] Mixing ratio: Mix raw rhubarb and Glauber's salt in a 2:1 mass ratio. Pour the pulverized raw rhubarb powder and Glauber's salt powder into a three-dimensional motion mixer, set the mixer speed to 20 r / min, and the mixing time to 20 minutes to ensure that the two powders are mixed evenly and to avoid uneven distribution of components that may affect the efficacy.

[0037] II. Bag preparation:

[0038] Class A external dressing (15cm long);

[0039] Class B external dressing (20cm long);

[0040] Material Cutting: The support layer is made of medical-grade polyester fiber, which has good strength and stability. The support layer material is cut according to the dimensions of Class A external dressings (15cm long, 6cm wide) and Class B external dressings (20cm long, 6cm wide). The breathable layer is made of 50g / m² non-woven fabric, also cut to the corresponding dimensions. Air vents are created on the breathable layer using laser perforation technology. The vents have a diameter of 0.5mm and a spacing of 1cm, evenly distributed in an array to ensure breathability while preventing leakage of the herbal powder.

[0041] Bag assembly: Stack the cut support layer and breathable layer, with the support layer on the outside and the breathable layer on the inside. Use medical-grade sutures and overlock stitch to sew the edges together, forming the basic shape of the medicine-filling cavity. Leave a 5cm opening on one side for filling with traditional Chinese medicine powder.

[0042] Adhesive edge setup: Medical pressure-sensitive adhesive is adhered to the outer perimeter of the support layer to form an adhesive edge. The width of the pressure-sensitive adhesive is 0.5cm, and a release paper is placed over the pressure-sensitive adhesive, with the edge of the release paper extending 0.5cm beyond the pressure-sensitive adhesive for easy removal during use.

[0043] III. Loading and Sealing

[0044] Quantitative filling: An automatic quantitative filling machine is used to accurately fill the mixed Chinese herbal powder into the filling cavity of the bag. Each Class A external application pack contains 90g of medicine (60g raw rhubarb and 30g Glauber's salt), and each Class B external application pack contains 120g of medicine (80g raw rhubarb and 40g Glauber's salt). The filling error is controlled within ±0.2g to ensure consistent efficacy of each external application pack.

[0045] Sealing process: After filling, the pre-reserved opening is sealed using hot-press sealing technology. The hot-press temperature is set to 120℃, the pressure to 0.5MPa, and the sealing time to 3 seconds to ensure a tight seal and prevent the Chinese medicine powder from getting damp or leaking. A 0.5cm wide sealing edge is formed at the seal, and the sealing edge is flat and wrinkle-free.

[0046] IV. Outer Packaging

[0047] Individual vacuum packaging: The prepared individual external dressing packets are placed in transparent composite vacuum bags and vacuum-packed using a vacuum packaging machine to prevent the Chinese medicine powder from deteriorating due to contact with air. The top and bottom edges of the vacuum bag are serrated with a 1cm spacing between the serrations for easy tearing when changing the dressing.

[0048] Cardboard Box Packaging: Produce corresponding cardboard boxes according to the dimensions of the Class A and Class B outer packaging packages. Class A boxes are 18cm long, 8cm wide, and 5cm thick; Class B boxes are 24cm long, 10cm wide, and 8cm thick. Place three vacuum-packed outer packaging packages inside each box, along with a small packet of 5g silica gel desiccant. Seal the box and label the surface with the product name, specifications, production date, shelf life, ingredients, and usage instructions.

[0049] Example 2: How to use a traditional Chinese medicine external application pack

[0050] (1) Patient assessment: Before use, medical staff need to assess the patient's surgical incision, including the type of incision (transverse incision, longitudinal incision, oblique incision), incision length, healing status, and whether the patient has a history of allergy to raw rhubarb, Glauber's salt, or the external dressing material. If the patient has a history of allergy, this external dressing is prohibited from use; if the incision has obvious infection, excessive bleeding, etc., appropriate treatment should be given first, and use should be considered after the condition stabilizes.

[0051] (2) Selection of external dressing: Select the appropriate external dressing according to the type and length of the incision. When the incision length is less than 15cm, select a Class A external dressing; when the incision length is greater than 15cm, select a Class B external dressing. At the same time, check whether the outer packaging of the external dressing is intact and whether the vacuum packaging is leaking. If there is any damage or leakage in the packaging, do not use it.

[0052] (3) Environment and tool preparation: Prepare sterile operating trays, saline, sterile gauze, iodine and other items required for dressing change. Ensure that the dressing change environment is clean and dry, with the temperature controlled at 22-25℃ and the humidity controlled at 50%-60%, to reduce the contamination of the incision by the external environment.

[0053] (4) Incision cleaning and disinfection: Medical staff, following the aseptic operation procedure, wear sterile gloves and first gently wipe the surgical incision and surrounding skin with saline cotton balls (within a radius of 5cm centered on the incision) to remove secretions and dirt from the surface of the incision. Then, disinfect the incision and surrounding skin with iodine cotton balls. The disinfection range is also centered on the incision with a radius of 5cm. The disinfection sequence is to wipe in a spiral motion from the incision to the surrounding skin. Disinfect twice in total. After each disinfection, wait for the iodine to dry naturally.

[0054] (5) Placement of the dressing: Tear off the serrated edge of the vacuum bag of the dressing, open the vacuum bag, take out the dressing, and then tear off the release paper from the adhesive edges around the support layer of the dressing. Place the dressing with the breathable layer facing the surgical incision, accurately covering the incision, ensuring that the dressing completely covers the incision and is centered. Then gently press around the dressing to make the adhesive edges fit tightly against the patient's skin, fixing the dressing in place and preventing it from shifting.

[0055] (6) Fixation check: After the external dressing is placed, check whether it is firmly fixed and whether there are any signs of loosening. At the same time, ask the patient if there is any local discomfort, such as itching, increased pain, etc. If the patient experiences discomfort, the external dressing should be removed in time, the cause should be investigated and appropriate treatment should be given. Each external dressing is generally applied for 24 hours. After the external dressing is placed, use an abdominal binder to further fix the external dressing to prevent it from shifting or falling off due to the patient turning over at night.

[0056] During the external application period, medical staff need to regularly observe the patient's surgical incision, including whether there is any seepage, bleeding, redness, swelling, fever, or other symptoms, as well as whether the external dressing is damaged or the herbal powder is leaking. At the same time, they should monitor the patient's body temperature, blood routine, and other indicators to promptly detect any potential complications.

[0057] (7) Dressing change procedure: Dressings should be changed every other day. That is, after 24 hours of external application, the dressing should be removed, the incision should be cleaned and disinfected, and then a new dressing should be applied. The dressing should be changed until the patient is discharged after the surgical incision is sutured. If the incision is found to be healing well and there are no signs of fat liquefaction during the dressing change process, the dressing change frequency can be appropriately reduced according to the doctor's judgment. If fat liquefaction is found in the incision, the dressing change frequency should be increased, and the patient's condition should be closely observed. If necessary, the treatment plan should be adjusted.

[0058] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
