Description

Technical Field

[0001] The utility model relates to the technical field of medical hydrogel films, in particular to a sterile medical hydrogel film. Background Art

[0002] Medical hydrogel patch is a patch structure that uses medical hydrogel as the main material. Medical hydrogel is semi-permeable and has the effects of blocking bacteria, preventing wound infection, and allowing oxygen and water to pass through.

[0003] During the use of medical hydrogel films, the medical hydrogel films rely on isolation materials to prevent direct contact with bacteria. However, the sides of the medical hydrogel films do not have structures that can prevent contact with bacteria. This may cause bacteria to enter through the sides of the medical hydrogel films, affecting the safety of the medical hydrogel films. Utility Model Content

[0005] A sterile medical hydrogel patch comprises a main body, wherein the upper and lower sides of the main body are both bonded with protective layers, and the four sides of the two protective layers facing each other are bonded together;

[0006] The main body includes a protective layer, a first connecting layer, a core layer, a second connecting layer, and a surface layer. The top surface of the protective layer is bonded to the bottom surface of the first connecting layer, the top surface of the first connecting layer is fixedly connected to the bottom surface of the core layer, the top surface of the core layer is fixedly connected to the bottom surface of the second connecting layer, and the top surface of the second connecting layer is fixedly connected to the bottom surface of the surface layer.

[0007] Through the above technical solution, the basic use functions of the device are guaranteed.

[0008] Furthermore, the two protective layers are both made of polyethylene.

[0009] Furthermore, the first connecting layer and the second connecting layer are both made of adhesive-coated polyurethane.

[0010] Furthermore, the core layer is made of medical hydrogel.

[0011] Furthermore, the material of the protective layer is release paper.

[0012] Furthermore, the surface layer is made of non-woven fabric.

[0013] Through the above technical solution, the device has the effect of being breathable and isolating bacteria.

[0014] Furthermore, the upper sides of the left and right sides of the upper protective layer are fixedly connected to the first pull paper, and the lower sides of the left and right sides of the lower protective layer are fixedly connected to the second pull paper.

[0015] The above technical solution can make the device more convenient to use, reduce the difficulty of using the device, and increase the applicability of the device.

[0016] The technical effects and advantages of this utility model are:

[0017] The utility model utilizes the relative wrapping arrangement of two protective layers to ensure that the core layer in the main body will not be affected by the breeding of bacteria, and utilizes the arrangement of the surface layer non-woven fabric to ensure the relative breathability and bacteria isolation effect of the core layer, thereby ensuring the overall sterility effect of the device. Through the above structure, the device can avoid the problem of bacteria entering through the side, and can ensure that the entire device will not be invaded by bacteria, thereby ensuring the safety of the device and ensuring the sterility of the device by isolating bacteria.

[0018] The utility model utilizes the arrangement of the protection layer, the shield layer, the first connection layer, the core layer, the second connection layer and the surface layer to ensure better use of the device and enable the structure inside the device to better play its role.

[0028] like Figure 1-5 As shown, a sterile medical hydrogel film includes a main body 1, with protective layers 2 bonded to both the upper and lower sides of the main body 1, and the four sides of the two protective layers 2 are bonded together;

[0029] The main body 1 includes a protective layer 3, a first connecting layer 4, a core layer 5, a second connecting layer 6, and a surface layer 7. The top surface of the protective layer 3 is bonded to the bottom surface of the first connecting layer 4, the top surface of the first connecting layer 4 is fixedly connected to the bottom surface of the core layer 5, the top surface of the core layer 5 is fixedly connected to the bottom surface of the second connecting layer 6, and the top surface of the second connecting layer 6 is fixedly connected to the bottom surface of the surface layer 7. The relative wrapping arrangement of the two protective layers 2 can ensure that the core layer 5 in the main body 1 will not be affected by the growth of bacteria, and the non-woven fabric arrangement of the surface layer 7 can also ensure the relative breathability and bacteria isolation effect of the core layer 5, thereby ensuring the overall sterility effect of the device. Through the above structure, the device can avoid the problem of bacteria entering through the side, can ensure that the device as a whole will not be invaded by bacteria, ensure the safety of the device, and ensure the sterility of the device by isolating bacteria.

The arrangement of the protective layer 2, the protective layer 3, the first connecting layer 4, the core layer 5, the second connecting layer 6, and the surface layer 7 can ensure better use of the device and enable the structure inside the device to better function.

[0031] like Figure 2-5 As shown, in some embodiments, the upper sides of the left and right sides of the upper protective layer 2 are fixedly connected with the first paper pull 8, and the length of the first paper pull 8 is longer than the second paper pull 9, which can ensure that the two paper pulls have a certain length difference, thereby improving the performance of the device. The lower sides of the left and right sides of the lower protective layer 2 are fixedly connected with the second paper pull 9. The arrangement of the first paper pull 8 and the second paper pull 9 can make the device more convenient to use, reduce the difficulty of using the device, and increase the applicability of the device.
