Abstract
Description
Technical Field
[0001] This utility model relates to the field of coated paper technology, specifically to a puncture-resistant medical coated paper. Background Technology
[0002] Medical adhesive-coated paper is a widely used material in the medical field. The adhesive generally has good biocompatibility, ensuring that it will not have adverse effects on the human body. Its applications are wide-ranging; for example, in wound care, it can be used as the main material for bandages, adhering to the skin around the wound to protect it, prevent infection, and promote healing.
[0003] Medical coated paper typically consists of a paper substrate and a medical adhesive coated on it. Although medical coated paper is widely used in wound dressing, medical device fixation, and other applications, existing medical coated paper has insufficient puncture resistance. It is easily damaged when accidentally punctured by a sharp object, causing its protective function to fail and failing to meet the stringent safety and reliability requirements in medical procedures. Therefore, we propose a puncture-resistant medical coated paper. Utility Model Content

[0014] Furthermore, the thickness of the elastomeric coating is 50-100 μm, and the elastomeric coating is a polymeric elastic coating containing nano-silica.
[0015] Furthermore, the substrate layer is woven from a mixture of high-density cellulose fibers and polyester fibers, and the basis weight of the substrate layer is 80 g / m². 2 .

[0017] Furthermore, the mesh size of the glass fiber mesh layer is 180-220 mesh, and the diameter of the glass fibers in the glass fiber mesh layer is 10 μm.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

The antibacterial layer inhibits bacteria, while the ridges and ventilation grooves of the breathable layer facilitate airflow. The materials used in each layer of this design are carefully selected to meet medical requirements for safety, reliability, and breathability. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] This embodiment provides a technical solution:
[0031] Please see Figures 1-6 As shown, a puncture-resistant medical coated paper includes a release paper layer 1, with multiple coated paper components 2 on the top of the release paper layer 1; the coated paper components 2 include a substrate layer 20, a reinforcing layer 21, an antibacterial layer 22, a breathable layer 23, and a coated layer 24 arranged sequentially from top to bottom; the substrate layer 20 has an elastomer coating 200 on its top; the reinforcing layer 21 has a mesh structure; the bottom of the breathable layer 23 has multiple protruding ribs 230 fixed thereon, and a breathable groove 231 is formed between two adjacent protruding ribs 230; a glass fiber mesh layer 240 is embedded in the coated layer 24, and the glass fiber mesh layer 240 has a mesh structure.
[0032] In this embodiment, the adhesive layer 24 is a medical-grade polyurethane colloid, which is applied to the bottom of the breathable layer 23 using a coating process. The polyurethane colloid has strong adhesion, firmly bonding the breathable layer to other layers and improving the overall structural stability. The uniform coating process ensures consistent coating thickness, enhancing aesthetics and durability.
[0033] In this embodiment, the reinforcing layer 21 is bonded to the substrate layer 20 and the antibacterial layer 22, and the breathable layer 23 is bonded to the antibacterial layer 22. The bonding process ensures a tight bond between the layers, reduces the risk of delamination, and improves durability.
[0034] In this embodiment, the thickness of the elastomer coating 200 is 50-100 μm, and the elastomer coating 200 is a polymeric elastic coating containing nano-silica. The preferred thickness of the elastomer coating 200 is 80 μm, a design that ensures sufficient elasticity while avoiding the bulkiness caused by excessive thickness. The polymeric elastic coating possesses good elasticity and flexibility, resisting external pressure and deformation. The presence of nano-silica improves the coating's wear resistance, aging resistance, and hardness, extending its service life.
[0035] In this embodiment, the substrate layer 20 is woven from a mixture of high-density cellulose fibers and polyester fibers, and the basis weight of the substrate layer 20 is 80 g / m². 2 The hybrid weaving process gives the substrate layer 20 high strength and toughness, making it less prone to tearing or damage and improving its puncture resistance.
[0036] In this embodiment, the antibacterial layer 22 is made of silver ions for antibacterial purposes, and the nano-silver particles in the antibacterial layer 22 have a particle size of 8μm. Silver ions have a broad-spectrum antibacterial effect and can effectively kill or inhibit the growth of a variety of bacteria and viruses; the design of the nano-silver particles with a particle size of 8μm improves the antibacterial effect and penetration ability of the antibacterial layer 22.
[0037] In this embodiment, the glass fiber mesh layer 240 has a mesh size of 180-220, and the glass fibers in the glass fiber mesh layer 240 have a diameter of 10 μm. A preferred mesh size for the glass fiber mesh layer 240 is 200 mesh. This design ensures the uniformity and stability of the glass fiber mesh layer 240, while the 10 μm design improves the strength and toughness of the glass fiber mesh layer 240.
[0038] It should be added that the release paper layer 1 is made of release paper, which is a special kind of paper. One side of it is coated with anti-sticking substances such as silicone oil, which gives the other side good isolation properties. This prevents sticky materials, such as glue and self-adhesive, from easily sticking to it, making subsequent separation operations convenient. In this embodiment, the use of release paper layer 1 makes it convenient to fix multiple glued paper components 2 at the same time and facilitates the separation of glued paper components 2 later.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
