[0002] Light-cured technology is a method that uses specific wavelength ultraviolet or visible light radiation to excite the photosensitizer and monomer molecules to undergo photochemical reactions. This method makes the material link from the easily flowing small molecule state to the not easily flowing macromolecular aggregate. In the medical field, light-cured technology is widely used in the manufacture of materials with excellent physical properties and biocompatibility, such as dental filling materials, medical coatings and surgical membranes. The main advantages of this technology include fast curing speed, mild reaction conditions, stable product performance, etc. In summary, the light-cured iodine-containing surgical membrane structure is based on the application advantages of light-cured technology and iodine-containing materials in the medical field, aiming to optimize the preparation process, improve the performance and stability of the surgical membrane, to meet the demand of high-performance surgical membrane in the medical field. With the continuous progress of science and technology and the rapid development of the medical field, the research and application of light-cured iodine-containing surgical membrane structure will have broad prospects and important practical significance.

[0003] Therefore, the traditional surgical membrane has the problems of high sensitization and no antibacterial performance. UTILITY MODEL CONTENT

[0004] Therefore, the utility model provides a light-cured iodine-containing surgical membrane structure, aiming at solving the problems of high sensitization and no antibacterial performance of the traditional surgical membrane.

[0005] The utility model is realized as follows:

[0006] The utility model provides a light-cured iodine-containing surgical membrane structure, wherein, including the release base material layer, the use base material layer, the iodine-containing adhesive layer who sets gradually layer by layer, wherein, the iodine-containing adhesive layer connects the use base material layer with release base material layer, the iodine-containing adhesive layer is mixed by povidone iodine and light-cured UV acrylic acid hot melt adhesive, the iodine-containing adhesive layer is used for improving the antibacterial performance and light-cured characteristics of light-cured iodine-containing surgical membrane, the use base material layer selects PE film or polyurethane film, and be used to provide certain tensile strength and barrier property, the release base material layer includes glassine or white silica, and the release base material layer is used to transfer the mixed iodine-containing adhesive and protect the iodine-containing adhesive layer.

[0007] The technical effect of the light-cured iodine-containing surgical membrane structure is as follows: the iodine-containing adhesive layer is formed by mixing povidone iodine and light-cured UV acrylic hot melt adhesive, the light-cured technology can quickly realize the curing of the material under mild conditions, thereby improving the production efficiency; at the same time, the light-cured process also helps to improve the uniformity and stability of the material, so that the performance of the surgical membrane is more reliable. In addition, the iodine-containing material has excellent antibacterial performance and can effectively kill or inhibit the growth of bacteria, thereby reducing the risk of infection at the surgical site. Therefore, the introduction of iodine-containing material into the surgical membrane can improve the anti-infection ability of the surgical membrane and help to promote the healing of the surgical site.

[0008] On the basis of the above technical scheme, the light-cured iodine-containing surgical membrane structure of the utility model can also be improved as follows:

[0009] Among them, the antibacterial component in the iodine-containing adhesive layer is povidone iodine.

[0010] Further, the glue in the iodine-containing adhesive layer adopts light-cured UV acrylic hot melt adhesive.

[0011] Further, the release substrate layer and the use substrate layer are respectively arranged on both sides of the iodine-containing adhesive layer and are connected by the adhesion of the iodine-containing adhesive layer.

[0012] The mixing ratio of povidone iodine and light-cured UV acrylic hot melt adhesive in the iodine-containing adhesive layer can be adjusted according to specific needs to optimize the antibacterial effect and physical properties after curing. For example, increasing the proportion of povidone iodine can enhance the antibacterial performance, but may affect the adhesion after light curing; on the contrary, increasing the proportion of UV acrylic hot melt adhesive can improve the adhesion after curing and the adhesion strength of the use substrate.

[0013] The PE film or PU film of the use substrate layer can be surface treated, such as corona treatment, plasma treatment or coating adhesive, etc., to increase the bonding strength between the cured layer and the use substrate layer.

[0014] The thickness of the iodine-containing adhesive layer can be adjusted according to the expected antibacterial effect and light-cured degree. A thinner cured layer helps to improve the light-cured degree, but may reduce the antibacterial performance due to insufficient overall effective iodine; while a thicker cured layer can provide more stable antibacterial effect, but the curing degree will be reduced. Therefore, by accurately controlling the thickness of the cured layer, the best performance balance can be achieved.

[0015] The surgical membrane structure needs to be strictly sterilized before use to ensure its safety in surgery. Sterilization can be carried out by gamma ray sterilization to meet the sterilization requirements of hospitals and operating rooms.

[0016] Rapid curing is achieved by irradiation with a specific wavelength of ultraviolet light source. The curing time is generally between a few seconds to tens of seconds, depending on the thickness of the curing layer and the intensity of the ultraviolet light source.

[0017] The surgical film structure can be easily peeled off from the surgical area after the operation is completed, leaving no residue. Due to the tensile strength and barrier properties of the use substrate layer, the surgical film structure will not tear during peeling, ensuring the convenience and safety of use.

[0018] Compared with the prior art, the beneficial effects of the light-cured iodine-containing surgical film structure provided by the utility model are: the iodine-containing adhesive layer is composed of povidone iodine and light-cured UV acrylic hot melt adhesive, the use of light-curing technology can quickly realize the curing of the material under mild conditions, thereby improving the production efficiency; at the same time, the light-curing process also helps to improve the uniformity and stability of the material, making the performance of the surgical film more reliable. And the iodine-containing material has excellent antibacterial performance, can effectively kill or inhibit the growth of bacteria, thereby reducing the risk of infection at the surgical site. Therefore, the introduction of iodine-containing material into the surgical film can improve the anti-infection ability of the surgical film and help to promote the healing of the surgical site. It can solve the problems of unstable material performance and low antibacterial performance of traditional iodine-containing surgical film. BRIEF DESCRIPTION OF DRAWINGS
