Abstract

The invention belongs to the technical field of peritoneal dialysis, and particularly relates to a novel peritoneal dialysis tube. The novel peritoneal dialysis tube comprises a peritoneal dialysis tube body and two sleeve rings which are arranged on the peritoneal dialysis tube body, the peritoneal dialysis tube body is divided into a tube internally abdominal inner section, a subcutaneous tunnelsection and an externally abdominal outer section by the two sleeve rings, wherein the peritoneal dialysis tube body is prepared from a crosslinked polyolefin material, the sleeve rings are preparedfrom a polyester material, and the peritoneal dialysis tube body is of an integrally shaped structure. The novel peritoneal dialysis tube has the advantages that the peritoneal dialysis tube is prepared from the crosslinked polyolefin material with the mass percentage of n -hexane leeching matter lower than 0.5, the small amount of molecular foreign matters which are introduced into the body is greatly reduced, and therefore the inducing rate of peritonitis in the peritoneal dialysis process is reduced, the sleeve rings are prepared by adopting the polyester material, a fine filament meshed structure of the material allows body tissues to adhere faster and deeper, therefore the peritoneal dialysis tube is effectively fixed, and the infection and discomfort caused by catheter displacement are reduced.

Description

technical field [0001] The invention belongs to the technical field of peritoneal dialysis, in particular to a novel peritoneal dialysis tube. Background technique [0002] There are three commonly used treatment methods for renal failure (uremia): hemodialysis, peritoneal dialysis, and kidney transplantation. Peritoneal dialysis uses the peritoneum as an exchange medium to expel waste, toxins, and excess water from the body. Patients using peritoneal dialysis technology can maintain their lives, and peritoneal dialysis can last for more than 20 years in western developed countries. At the same time, peritoneal dialysis is a new technology being promoted in our country, which is suitable for our national conditions. The peritoneal dialysis catheter is a catheter used in peritoneal dialysis technology for exchanging fluids inside and outside the body, and needs to be placed in the peritoneal cavity of the human body. [0003] The material of existing peritoneal dialysis tub...
