In summary, the waterproof film for the infusion port provided in this embodiment can provide reliable waterproof protection for the needle and the medical film outside the infusion port, and meet the patient's needs for cleaning the body during the needle retention period. Moreover, the structure and production process of the waterproof film for the infusion port are simple, the cost of use is low, and it will not excessively increase the economic burden on patients.

[0039] For example, Figure 1 and Figure 2 As shown, the waterproof cover 10 includes a protruding portion 11 and a connecting portion 12 connected to each other, the outer adhesive portion 30 is connected to the connection between the protruding portion 11 and the connecting portion 12, and the opening end of the waterproof cover 10 is arranged at one end of the connecting portion 12 away from the protruding portion 11.

[0040] Furthermore, the connection part 12 is configured as a flexible structure. When in use, the needle is first inserted into the waterproof cover 10, so that the inner adhesive part 20 is arranged around the outer periphery of the original medical film, and then the inner adhesive part 20 is pasted on the patient's skin to achieve the first layer of waterproofing; then the connection part 12 is bent, so that the outer adhesive part 30 is arranged around the outer periphery of the inner adhesive part 20, and then the outer adhesive part 30 is pasted on the patient's skin to achieve the second layer of waterproofing.

[0041] Exemplarily, the connecting portion 12 is made of sterile soft silicone or sterile soft plastic.

[0042] Exemplarily, the connecting portion 12 is configured as a transparent or translucent structure so that the patient can observe the medical film and the needle in the waterproof cover 10 .

[0043] Exemplarily, the raised portion 11 is configured as a transparent or semi-transparent structure so that the patient can observe the medical film and the needle in the waterproof cover 10 .

[0044] Exemplarily, the raised portion 11 is configured as a rigid structure, the height of which exceeds the length of the needle protruding from the patient's skin, so as to prevent the needle from being bumped and play a role in shielding the needle.

[0045] Exemplarily, the protrusion 11 is made of sterile hard plastic or resin material.

[0046] Exemplarily, both the inner adhesive portion 20 and the outer adhesive portion 30 are configured as flexible structures to adapt to the uneven body surface of the patient, improve the fit with the patient's skin, and ensure waterproof performance.

[0047] Optionally, the inner adhesive portion 20 and the outer adhesive portion 30 are made of waterproof material, specifically waterproof tape, to ensure waterproof performance.

[0048] Exemplarily, the inner adhesive portion 20 and the outer adhesive portion 30 have the same shape, and the inner diameter of the outer adhesive portion 30 is larger than the outer diameter of the inner adhesive portion 20. Figure 2 As shown, the inner adhesive portion 20 and the outer adhesive portion 30 are both configured as annular structures, and the shape of the inner adhesive portion 20 is adapted to the circular medical film.

[0049] For example, Figure 1 and Figure 2 As shown, the waterproof film for the infusion port also includes an inner release paper 40, which is attached to and completely covers the sticky side of the inner adhesive portion 20.
