However, the subclavian semi-permanent hemodialysis tube is easily in contact with water during daily shower, and the contact between the water during shower and the puncture site can easily cause infection at the puncture site. Since the subclavian semi-permanent hemodialysis tube is inserted into the deep vein, if infected, the subclavian semi-permanent hemodialysis tube needs to be removed and replaced, and severe infection can even cause death.

[0004] The patent with publication number CN220070307U discloses a hemodialysis tube airtight protection bag, which includes a patch and a bag body. The hemodialysis tube exposed outside the human body is placed in the bag body through the bag opening to protect the hemodialysis tube from contamination. However, since the space in the bag body is relatively large, the hemodialysis tube is easily shaken in the bag body during shower. If the patient moves too much, the end of the hemodialysis tube can swing away from the patient and hit the bag body, and the hemodialysis tube can exert a force away from the patient on the bag body, which can easily cause the bag body to fall off the patient, resulting in the hemodialysis tube being separated from the bag body.
