In addition, the three sides of the support layer 21, the heat-resistant layer 22 and the wear-resistant layer 23 except the top are hot-pressed and fixed to the front of the dialysis cardboard 10. The three sides of the support layer 21, the heat-resistant layer 22 and the wear-resistant layer 23 are hot-pressed and fixed to the front of the dialysis cardboard 10 layer by layer at different positions, so that the sealing of the side of the packaging layer 20 is stronger, preventing the packaging layer 20 from being torn by external force and causing damage.

[0021] Please refer to Figure 1 and Figure 2The sealing assembly 30 includes a first elongation layer 31, a first adhesive layer 32, a second elongation layer 33, a second adhesive layer 34, a third elongation layer 35, a third adhesive layer 36, and an extension member 37. The first elongation layer 31 is fixedly arranged on the top of the support layer 21, the first adhesive layer 32 is arranged on the top of the dialysis paperboard 10, and the first elongation layer 31 is adhered to the front of the first adhesive layer 32, the second elongation layer 33 is fixedly arranged on the top of the heat-resistant layer 22, the second adhesive layer 34 is fixedly arranged on the top of the first adhesive layer 32, the second elongation layer 33 is adhered to the front of the second adhesive layer 34, and the third elongation layer 35 is fixedly arranged on the wear-resistant layer 23. The third adhesive layer 36 is fixedly arranged on the top of the second adhesive layer 34, the third elongation layer 35 is adhered to the front of the third adhesive layer 36, the first elongation layer 31 is fixedly connected to the second elongation layer 33, and the second elongation layer 33 is fixedly connected to the third elongation layer 35. The first elongation layer 31, the second elongation layer 33 and the third elongation layer 35 on the top of the support layer 21, the heat-resistant layer 22 and the wear-resistant layer 23 are respectively adhered to the first adhesive layer 32, the second adhesive layer 34 and the third adhesive layer 36 at different positions, so that the sealing part of the packaging layer 20 can be sealed layer by layer, the seal is tighter, and the tear resistance of the packaging layer 20 is improved.

[0022] Please refer to Figures 1-4 The extension member 37 is arranged on the top of the third extension layer 35. The extension member 37 includes an extension belt 371, a fourth adhesive layer 372, and an anti-slip strip 373. The extension belt 371 is fixedly arranged on the top of the third extension layer 35, and one end of the extension belt 371 extends into the back of the dialysis cardboard 10. The fourth adhesive layer 372 is fixedly arranged on the top of the dialysis cardboard 10, and one end of the extension belt 371 is adhered to the top of the extension belt 371. Multiple anti-slip strips 373 are fixedly arranged on the front of the extension belt 371, and multiple anti-slip strips 373 are equidistantly arranged in parallel at one end of the extension belt 371. The extension tape 371 is bent and extends into the back of the dialysis cardboard 10. One end of the extension tape 371 is fixed to the back of the dialysis cardboard 10 in conjunction with the fourth adhesive layer 372. When the extension tape 371 is torn, it becomes the portion from which the third elongation layer 35 extends. This facilitates the user to forcefully tear the first elongation layer 31, the second elongation layer 33, and the third elongation layer 35, which are fixed together, off the first adhesive layer 32, the second adhesive layer 34, and the third adhesive layer 36, thereby opening the sealed packaging layer 20 and removing the medical device. The multiple anti-slip strips 373 provide an anti-slip function, making it easier to apply force when tearing.

[0023] This application can explain its functional principles through the following operation methods:

[0024] During use, the support layer 21 on the front of the dialysis cardboard 10 provides support, the heat-resistant layer 22 can withstand the high-temperature sterilization process, and the wear-resistant layer 23 is arranged on the outermost side to play a protective role to ensure the integrity and functionality of the medical device. The support layer 21, the heat-resistant layer 22 and the wear-resistant layer 23 are sealed layer by layer on the three sides except the top. External bacteria and air need to pass through triple sealing to enter the interior of the packaging layer 20, thereby improving the sealing of the sides of the packaging layer 20. The first elongation layer 31, the second elongation layer 33 and the third elongation layer 35 on the top of the support layer 21, the heat-resistant layer 22 and the wear-resistant layer 23 are respectively adhered to the first adhesive layer 32, the second adhesive layer 34 and the third adhesive layer 36 at different positions, so that the packaging layer 20 The top is sealed multiple times to improve the sealing performance and prevent the packaging layer 20 from being easily torn by external forces, which would affect the transportation process of the medical devices. One end of the extension tape 371 on the top of the third extension layer 35 is bent around the back of the dialysis cardboard 10 and adhered to the fourth adhesive layer 372. When it is necessary to tear the packaging layer 20, press the multiple anti-slip strips 373 at one end of the extension tape 371 with your hand to tear the extension tape 371 off the fourth adhesive layer 372. Then, press the extension tape 371 again to tear the third extension layer 35, the second extension layer 33 and the first extension layer 31 off the third adhesive layer 36, the second adhesive layer 34 and the first adhesive layer 32 in sequence, so that the packaging layer 20 is opened and the medical devices inside can be taken out.

Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.
