[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] In a first typical embodiment of this application, according to some specific embodiments of this application, this application provides a self-adhesive, breathable radionuclide scar repair patch, such as... Figure 1 As shown, it includes a waterproof layer 1, an active layer 2 and an adhesive layer 3. The adhesive layer 3 is connected to one side of the waterproof layer 1, and the active layer 2 is disposed inside the waterproof layer 1. Along the thickness direction of the waterproof layer 1, a first vent hole 10 is provided inside the waterproof layer 1, and the active layer 2 is disposed away from the first vent hole 10.
[0026] In the above-described solution, the self-adhesive breathable radionuclide scar repair patch of this utility model includes a waterproof layer 1, an active layer 2, and an adhesive layer 3. The active layer 2 contains a radionuclide for scar repair. The adhesive layer 3 is connected to one side of the waterproof layer 1, securing the radionuclide scar repair patch to the body. This makes application convenient, reduces application time and difficulty, and avoids radiation exposure risks for medical personnel. The active layer 2 is located within the waterproof layer 1, and the waterproof layer 1 protects the active layer 2, preventing radionuclide leakage. Along the thickness direction of the waterproof layer 1, a first vent 10 is provided within the waterproof layer 1. The first vent 10 increases the breathability of the radionuclide scar repair patch, improving application comfort. To prevent leakage of the active layer 2 through the first vent 10, the active layer 2 is positioned away from the first vent 10.
[0027] According to some specific embodiments of this application, the diameter of the first vent 10 is 0.01mm-0.5mm.
[0028] Optionally, the diameter of the first vent 10 can be 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.08mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, or 0.5mm, etc.
[0029] By limiting the diameter of the first ventilation hole 10 to a reasonable range, it is beneficial to improve the breathability of the radionuclide scar repair patch, while avoiding the pore size being too large, occupying too much area, affecting the arrangement of the active layer 2, and thus affecting the repair effect.
[0030] According to some specific embodiments of this application, the cross-section of the first vent 10 can be circular, elliptical, or square, preferably circular, depending on actual usage needs. Any three vents connected together form an equilateral triangle to achieve maximum air permeability.
[0031] According to some specific embodiments of this application, a plurality of first vent holes 10 are arranged in an array, and the distance between two adjacent first vent holes 10 is 1mm-10mm.
[0032] Optionally, the distance between two adjacent first vent holes 10 can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm, etc.
[0033] In the above scheme, by arranging multiple first ventilation holes 10 in an array, an all-round breathability effect can be achieved, further improving the breathability of the radionuclide scar repair patch. Furthermore, by limiting the spacing between two adjacent first ventilation holes 10 within a reasonable range, it is more conducive to improving breathability. Through the layout that is conducive to the active layer 2, the repair effect is improved.
[0034] According to some specific embodiments of this application, such as Figure 2 As shown, the distance a between the edge of the first vent 10 and the sidewall of the adjacent active layer 2 is 0.1mm-0.5mm.
[0035] Optionally, the distance 'a' between the edge of the first vent 10 and the sidewall of the adjacent active layer 2 can be 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, or 0.5mm, etc.
[0036] In the above scheme, by limiting the distance 'a' between the edge of the first vent 10 and the sidewall of the adjacent active layer 2 to a reasonable range, the waterproof layer 1 can ensure the all-round sealing of the active layer 2, and prevent radionuclide leakage due to the design of the first vent 10.
[0037] According to some specific embodiments of this application, the active layer 2 is a mixture of a carrier and a nuclide, wherein the carrier includes silicone material or polyurethane material; the active layer 2 is adhered to the waterproof layer 1 or chemically cross-linked into an integral structure.
[0038] Nuclide includes 24 Na、 32 P, 38 Cl、 40 K, 41 Ar、 42 K, 76 As、 86 Ru、 89 Sr、 90 Sr、 90 Y、 106 Ru、 106 Rh、 166 Ho、 177 Lu、 188 Re、 210 Tl、 131 I, 125 I, 103 One or more of Pd.
[0039] In the above scheme, the active layer 2 is a mixture of carrier and nuclide. The carrier can disperse and support the nuclide, ensuring its uniform distribution and preventing displacement, migration, or leakage. To make the active layer 2 more stable within the waterproof layer 1, silicone or polyurethane materials can be used as carrier materials. These materials can adhere to the waterproof layer 1 or be chemically cross-linked into an integrated structure, thereby achieving better stability.
[0040] According to some specific embodiments of this application, the waterproof layer 1 is made of silicone or polyurethane material; the adhesive layer 3 is made of silicone gel.
[0041] In the above scheme, by selecting a suitable type of waterproof layer 1 material, a better waterproof effect can be achieved, and it can also play a certain role in adhesion. The adhesive layer 3 is specifically made of silicone gel. Silicone gel has stable physicochemical properties, is not significantly affected by temperature, has good adhesion and sealing performance, and also has good self-healing properties, which can improve the repair effect of the radionuclide scar repair patch.
[0042] According to some specific embodiments of this application, the distance between the upper surface of the active layer 2 and the upper surface of the waterproof layer 1 is 0.1mm-1mm; and / or, the distance between the lower surface of the active layer 2 and the lower surface of the waterproof layer 1 is 0.1mm-1mm.
[0043] Optionally, the distance between the upper surface of the active layer 2 and the upper surface of the waterproof layer 1 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm; the distance between the lower surface of the active layer 2 and the lower surface of the waterproof layer 1 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm.
[0044] In the above scheme, by limiting the distance between the upper surface of the active layer 2 and the upper surface of the waterproof layer 1 and the distance between the lower surface of the active layer 2 and the lower surface of the waterproof layer 1 to a reasonable range, the active layer 2 can be more tightly wrapped by the waterproof layer 1, preventing leakage.
[0045] According to some specific embodiments of this application, such as Figure 1 and Figure 3 As shown, the adhesive layer 3 has a second vent 30 at a position corresponding to the first vent 10, which communicates with the first vent 10.
[0046] In the above scheme, by opening a second vent 30 at the position corresponding to the first vent 10 on the adhesive layer 3, which communicates with the first vent 10, the breathability of the radionuclide scar repair patch can be further improved.
[0047] According to some specific embodiments of this application, the thickness of the active layer 2 is 0.1mm-1mm; the thickness of the waterproof layer 1 is 0.3mm-3mm; and the thickness of the adhesive layer 3 is 0.1mm-0.5mm.
[0048] Optionally, the thickness of the active layer 2 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm; the thickness of the waterproof layer 1 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.5mm, 2mm, 2.5mm or 3mm; and the thickness of the adhesive layer 3 can be 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm or 0.5mm.
[0049] In the above scheme, by limiting the thickness of the active layer 2, the waterproof layer 1 and the adhesive layer 3 to a reasonable range, the layers can play a better synergistic role, thereby improving the breathability and repair effect of the radionuclide scar repair patch.
[0050] In a second typical embodiment of this application, according to some specific embodiments of this application, this application also provides a method for preparing a self-adhesive breathable radionuclide scar repair patch, comprising the following steps:
[0051] First, a waterproof layer material is applied as a waterproof layer base. An adhesive layer is applied to one side of the waterproof layer base. An active layer material is applied to the side of the waterproof layer base away from the adhesive layer. After the active layer material dries, an active layer is formed. A first perforator arranged in an array is used on the active layer to penetrate the active layer and pass through the adhesive layer to form a ventilation channel.
[0052] Then cover the active layer with a waterproof layer material, covering the active layer and the ventilation holes;
