Background technique

Peritoneal dialysis, as one of the renal replacement therapies for patients with uremia, has been widely used clinically. At the same time, there are also certain risks and hidden dangers in the process of changing fluids. There are two main aspects: 1. Catheter pulling: the process of changing fluids Among them, due to the effect of gravity, it is easy to cause the catheter to be pulled. At present, many peritoneal dialysis centers in China use iron clips or adhesive plasters to fix them. Good control; 2. After the peritoneal dialysis fluid and the short peritoneal dialysis tube are connected, the protection of the joint is currently divided into two types by many peritoneal dialysis centers in China: one is wrapped with a small handkerchief or gauze, and there are Failure to replace and clean in time may lead to problems such as bacterial growth and high cost of gauze; the other type is protected by the outer packaging of iodophor caps, but patients need to keep them reasonably, and the peritoneal dialysis center cannot provide backup for patients.
