Description

Technical Field

[0001] The utility model relates to the field of medical dressings, in particular to a dressing for peritoneal dialysis. Background Art

[0002] Peritoneal dialysis is a dialysis method that uses the body's own peritoneum as a dialysis membrane.

The screw barrel 4 rotates on the threaded barrel 7 at the same time. When the dressing body 1 is applied, the catheter is passed through the incision 2 of the dressing body 1 until it reaches the central opening of the dressing body 1. The sealing pad 14 on the incision 2 can prevent the catheter from moving out of the incision 2 by itself. The heightened baffle 16 on the dressing body 1 can prevent the catheter from bending from the end and squeezing the dressing body 1, resulting in a poor dressing effect. When the dressing is completed, the elastic band 13 is wrapped around the patient to enhance the fit between the dressing body 1 and the tunnel opening and prevent the dressing body 1 from slipping.
