Abstract
Description
Technical Field
[0001] This invention relates to a three-pole wound shield self-rescue kit, belonging to the field of trauma emergency technology. Background Technology
[0002] Existing emergency wound dressings and first aid kits mainly come in the following forms:
[0003] (1) Ordinary sterile gauze with tape / bandage: only has the functions of absorbing exudate, covering the wound and simple fixation;
[0004] (2) Band-aid type small dressings: only suitable for small wounds, with a single function;
[0005] (3) Traditional oil gauze / Vaseline gauze: Oily medicine is applied to prevent adhesion, but the oil is directly exposed and is easy to dry, evaporate and run off;
[0006] (4) Ordinary elastic bandages: require separate scissors for cutting and tape for fixing, which is cumbersome to operate.
[0007] Main drawbacks of existing technology:
[0008] (1) Single function: Ordinary dressings only have a single covering / absorption function and lack a multi-functional layered design of "isolation and antibacterial - antibacterial repair - self-adhesive fixation", making it difficult to meet the wound care needs in complex and harsh environments such as outdoors and battlefields.
[0009] (2) Oil-based products are prone to failure: Traditional oil-based antibacterial / repairing solutions are directly applied or simply soaked in dressings. When exposed to air, the oil is prone to drying, evaporation, and loss, which leads to premature failure of the antibacterial and repairing ingredients and makes it difficult to exert a stable effect over a longer period of time.
[0010] (3) Inconvenient to operate: Traditional bandaging requires cutting the bandage with scissors and preparing additional fixing tape. In single-person self-rescue and emergency situations (outdoor, home, battlefield), the operation is cumbersome and time-consuming, and non-professionals cannot complete it in a standardized manner.
[0011] (4) Lack of standard procedures: There are no step-by-step, standardized self-rescue bandaging methods. Ordinary people are prone to problems such as bandaging too tightly / too loosely, dressing displacement, and secondary contamination when in an emergency.
[0012] Therefore, the present invention proposes a new solution. Summary of the Invention
[0013] The main purpose of this invention is to address the shortcomings of existing technologies by providing a three-pole wound shield self-rescue kit.
[0014] The objective of this invention can be achieved by adopting the following technical solution:
[0015] A three-dimensional wound shield self-rescue kit includes:
[0016] It contacts the wound layer, adheres to the wound surface, and can provide physical isolation, bacterial inhibition, and absorption of exudate;
[0017] The intermediate functional layer, consisting of a mesh-like oil film made of antibacterial oil and bandage dressing, is breathable and can lock in fluid for slow release and provide antibacterial repair to the wound.
[0018] The outer layer has elastic self-adhesive properties for securing the entire structure.
[0019] The contact wound layer and the outer layer are an integral composite structure, and the intermediate functional layer is located between the contact wound layer and the outer layer.
[0020] Furthermore, the composition ratio of the antibacterial oil is as follows: 50%-60% sesame extract, 20%-30% walnut extract, 5%-10% camellia oil extract, 3%-4% olive oil extract, 2%-5% saffron extract, and 1%-5% cuttlebone extract.
[0021] Furthermore, the method for preparing the antibacterial oil is as follows:
[0022] Step 1: Mix the sesame extract, camellia oil extract, and olive oil extract at a constant temperature of 40℃ on low speed for 20 minutes until well combined.
[0023] Step 2: After cooling to room temperature, add walnut extract and perform static fusion at room temperature. Then add saffron extract and cuttlebone extract, and heat the temperature to 120℃-140℃ and maintain pressure for 6 hours.
[0024] Step 3: After cooling to room temperature, filter the solution using a 100-mesh steel sieve to obtain the antibacterial oil.
[0025] Preferably, the wound-contacting layer is 100% combed degreased cotton fiber medical gauze.
[0026] Preferably, the outer layer is a polypropylene fiber self-adhesive bandage.
[0027] Preferably, when the microfibers of the self-adhesive bandage are heated at high temperature, the fibers naturally curl up to form several small hooks, so that the fibers can hook onto each other.
[0028] Furthermore, the structure of the mesh oil film is that the antibacterial oil is coated on the outer surface of the bandage dressing, while retaining the original mesh of the internal fibrous fabric of the bandage dressing to form a breathable channel.
[0029] A method for using a three-pronged wound shield self-rescue kit includes the following steps:
[0030] Step 1: Clean the wound;
[0031] Step 2: Align the contact layer with the wound surface and apply it.
[0032] Step 3: Wrap and stick the outer layer together, then tear off the outer layer.
[0033] Preferably, the outer layer is longer than the contact wound layer and the intermediate functional layer.
[0034] Beneficial technical effects of the present invention: A three-pole wound shield self-rescue kit according to the present invention:
[0035] 1. It provides a composite structure integrating three functional layers: a contact wound layer, an intermediate functional layer, and an outer layer, which simultaneously achieves the triple functions of isolation and antibacterial action, antibacterial repair, and elastic self-adhesive fixation.
[0036] 2. By setting up a mesh-like oil film, the antibacterial oil can be stably coated and locked inside the dressing, solving the problems of oil drying and loss and failure, and will not affect breathability to avoid wound soaking.
[0037] 3. By integrating the contact wound layer with the outer layer, the bandage retains its elastic self-adhesive and tear-free properties, enabling quick and standardized bandaging by a single person. Detailed Implementation

[0078] Antibacterial oil components / formulation
[0079] Ingredient ratio:
[0080] Sesame extract 50%-60%, walnut extract 20%-30%, camellia oil extract 5%-10%, olive oil extract 3%-4%, saffron extract 2%-5%, cuttlebone extract 1%-5%;
[0081] Preparation method: soaking, low temperature, pressurization, filtration:
[0082] Sesame oil, camellia oil, and olive oil are mixed at a constant temperature of 40℃ and low speed for 20 minutes. Then, the pre-treated walnut mixture is added and blended at room temperature. Next, coarse saffron powder and fine cuttlebone powder are added and heated to 120℃-140℃ and maintained under pressure for 6 hours. Finally, after cooling to room temperature, they are stored or packaged using a 100-mesh steel sieve.
[0083] Material, pore size, and wrapping method of mesh oil coating:
[0084] Oil-net dressing: Liquid repair solution is sprayed onto a special compatible bandage dressing to form a stable oil-net sealing material, giving the bandage three functions: pressure, antibacterial, and anti-adhesion.
[0085] Covering method:
[0086] During the fiber embedding and coating stage, the antibacterial oil enters the capillary gaps between individual fibers inside the special material bandage dressing. The antibacterial oil coats the outer surface of each fiber, and the micro-tension and micro-pressure inherent in the bandage dressing itself locks in the antibacterial oil, forming a continuous oil phase thin layer on the outer wall of the fiber. The pores of the fiber material fabric between the bandage dressings retain hollow channels and are not completely blocked by the oil. Its microstructure is: the fiber is wrapped by the oil film, and the mesh channels are retained; the oil "coats the fiber" rather than "fills the pores".
[0087] The essence of embedding: capillary action + wetting and adsorption. The oil adheres to the fiber surface and fills the tiny gaps between the fibers, without completely saturating the yarn, thus preventing the entire bandage from becoming oil-soaked.
[0088] After the antibacterial oil is sprayed, it forms a mesh-like oil film based on the mesh of the elastic bandage fabric: ① The oil film covers individual fibers, and the gaps between the fibers retain ventilation channels, allowing moisture to escape from the wound and preventing wound maceration; ② The mesh-like oil film is flexible, and when the bandage is stretched and deformed, the oil mesh extends synchronously with the fibers and will not crack or fall off; ③ The mesh-like oil film isolates the bandage fibers, preventing the bandage yarn fibers from falling off and embedding into the open wound; at the same time, the oil film does not adhere to newly formed granulation tissue, and will not tear the wound when changing dressings or removing the bandage.
[0089] The function of the reticulated oil film:
[0090] ① Isolation: The oil mesh prevents the bandage yarn fibers from directly contacting the inner sterile gauze, thus avoiding fiber shedding and residue on the wound surface;
[0091] ②Slow release: The oil film is loaded with antibacterial active ingredients, which are slowly released to achieve antibacterial effect;
[0092] ③ Anti-adhesion: The oil phase isolation layer will not tear the gauze and new granulation tissue when changing dressings and removing bandages.
