[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1-7 As shown, the present invention provides a technical solution: a replaceable dressing film, comprising a dressing film, wherein the skin contact layer of the dressing film is medical silicone gel, and the protective layer is release paper.

[0033] A process for manufacturing replaceable dressing films includes the following steps:

[0034] S1: The output of material preparation and quality inspection serves as the input for base film treatment and bio-adhesive coating;

[0035] S2: The output of the base film treatment and bio-adhesive coating serves as the input for composite and molding;

[0036] S3: The output of the composite and molding process serves as the input for sterilization and detection;

[0037] S4: The output of sterilization and testing serves as the input for coating and packaging.

[0038] Preferably, the material preparation and quality inspection includes raw material preparation, and the material preparation and quality inspection further includes quality inspection. The material is a three-layer structure elastic dressing film, which includes a skin contact layer and a protective layer and is malleable within a temperature range of 80-100 degrees Celsius.

[0039] Specifically, material preparation and quality inspection serve as the starting point of the entire processing technology. Ensuring that all raw materials used meet medical-grade standards and product usage requirements guarantees the safety, effectiveness, and comfort of the final product. At the same time, accurate raw material specifications are a prerequisite for the smooth progress of subsequent processing steps and can reduce the defect rate.

[0040] Furthermore, the base film treatment and bio-adhesive coating includes base mold punching, and the base film treatment and bio-adhesive coating is provided with gel coating.

[0041] Specifically, the base film is a three-layer elastic dressing film. Using precision laser drilling or mechanical die punching equipment, a uniformly distributed array of micropores is punched into the base film. The numerous micropores allow air to circulate freely, preventing the skin from being in a humid and stuffy environment due to prolonged closure, greatly reducing the risk of allergies, itching, and eczema. The porous structure also makes the film more elastic, reduces the rigidity of the material, makes it softer, and better conforms to shape, making it almost imperceptible when worn, thus improving comfort. The gel uses medical-grade silicone gel, which has the characteristics of low irritation, low risk of allergies, good breathability, and high softness, and can significantly reduce local pressure and frictional heat.

[0042] Furthermore, the composite and molding process includes functional layer composites, which are covered with woven or mesh structure materials.

[0043] Specifically, the use of woven or mesh-like materials in the functional layer composite can improve breathability, enhance the stability of medical silicone gel on the base film while ensuring comfort and softness, improve support capacity, prevent gel deformation, help protect and fix the silicone gel so that it is not easy to fall off, and keep the area in contact with the skin dry. This can prolong the effective adhesion time of the film and prevent the decrease in adhesion or skin problems caused by moisture.

[0044] Furthermore, the lamination and molding process includes die-cutting and trimming, and further encompasses release film lamination and roller-assisted molding. The fixture table 3 and the rubber ring 1 are matched with the arc shape of the dressing film. A special-shaped dressing film 2 is provided between the fixture table 3 and the rubber ring 1 for auxiliary molding. A heating mold that matches the inner arc shape of the dressing film is selected, and the dressing film is placed on the heating mold. Pressure is applied to the dressing film within a temperature range of 80-100 degrees Celsius to perform thermoforming, so that it is highly consistent with the arc surface of the fixture table 3.

[0045] Specifically, die-cutting and trimming remove excess material around the edges. Trimming ensures that the edges of the base film are neat and burr-free, reducing discomfort or scratches to the skin during use or wear. This creates the final appearance and size of the dressing film, perfectly matching the contact surface or breast curve of the breast enhancement device, thus improving the wearer's comfort.

[0046] Furthermore, sterilization and testing include sterilization treatment and sterilization testing, which in turn include appearance testing and performance testing.

[0047] Specifically, sterilization ensures the sterility of the dressing / film product, preventing the introduction of pathogens during use and thus avoiding infection. Sterilization testing detects any residues, ensuring they remain within safe limits. Appearance and performance testing eliminate cosmetic defects and verify core functions. Visual inspection and imaging technology identify and remove products with cosmetic defects such as impurities, bubbles, adhesive residue, dimensional deviations, and scratches, ensuring product cleanliness and aesthetics. Sampling tests are conducted on key performance aspects such as breathability and comfort to ensure the product meets design standards and effectively and safely fulfills its intended physiological or corrective functions.

[0048] Furthermore, the film and packaging include surface film, and the film and packaging further encompass aseptic packaging.

[0049] Specifically, surface coating provides a smooth, flat surface that is easy to print on. Aseptic packaging, by packaging in a sterile environment and using coating materials that provide an effective barrier, can effectively prevent the invasion of microorganisms, reduce the risk of contamination during operation, and ensure the safety and effectiveness of dressings.

[0050] Furthermore, the lamination and packaging process includes packaging integrity testing and packaging seal testing, which employs a vacuum decay test.

[0051] Specifically, packaging integrity testing and packaging seal testing ensure the physical integrity of the product and prevent gas, liquid, or microorganisms from entering the interior through the edges of the packaging. Vacuum decay testing assesses the sealing performance of the packaging by measuring the rate at which the vacuum level inside the packaging decreases, preventing microbial intrusion and maintaining sterility.

[0052] Furthermore, the lamination and packaging include auxiliary markings, which are printed directly on the outside of the lamination using a printer.

[0053] Specifically, auxiliary labels can clearly indicate the product name, model, specifications, production date, expiration date, batch number, instructions for use, precautions, and manufacturer information, providing users with necessary product identification and traceability information.

[0054] Furthermore, the film coating and packaging process includes finished product warehousing, and the finished product warehousing is equipped with integrated temperature and humidity sensors.

[0055] Specifically, temperature and humidity sensors can continuously record temperature and humidity data in the warehouse, ensuring that environmental conditions meet product storage requirements, ensuring that products maintain their original quality during storage, extending shelf life, and ensuring that products meet usage requirements.

[0056] Working Principle: First, material preparation and quality inspection ensure the biocompatibility, safety, and dimensional accuracy of all raw materials from the source. Second, the base film treatment and bio-adhesive coating involve precision microporous array processing of the base film. These micropores allow free air circulation, effectively preventing the skin from being in a closed, humid environment, thus significantly reducing the risk of skin allergies, itching, or eczema. In the lamination and molding process, a layer of woven or mesh functional layer is laminated with the adhesive-coated base film to enhance stability and support. Die-cutting and edge trimming processes ensure smooth and neat product edges. Sterilization and testing ensure that all microorganisms are completely eliminated through reliable sterilization treatment, ensuring the product's sterile state and eliminating the risk of infection due to the introduction of pathogens during use. Finally, surface coating and sterile barrier packaging in a sterile environment create a sealed microenvironment, blocking the intrusion of external microorganisms and contaminants. Auxiliary labeling provides clear product information and usage instructions, while temperature and humidity sensors can monitor environmental data in real time, ensuring the product is stored under suitable conditions.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
