Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a fixing belt for peritoneal dialysis. Background Art

[0002] During peritoneal dialysis treatment, the fixation of the dialysis tube is an important part to ensure the smooth progress of the dialysis process. At present, the commonly used method of fixing the dialysis tube is mainly to use tape for adhesion fixation. First of all, the durability of tape fixation is poor. Due to the material and stickiness of the tape itself, its adhesion will gradually weaken over time, causing the dialysis tube to easily shift or even fall off. This not only affects the continuity of dialysis treatment, but may also cause a series of complications, such as infection, bleeding, etc. Secondly, when the tape is torn off, some adhesive will often remain on the patient's body surface, which may cause skin allergic reactions, such as redness, swelling, itching, etc.

[0003] Therefore, the utility model provides a fixing belt for peritoneal dialysis to solve the above problems. Utility Model Content
