Abstract

The invention provides a novel peritoneal dialysis catheter which comprises an anti-blocking pipeline capable of being filled with a fluid inside and a fluid filling device used for filling the anti-blocking pipeline with fluid. One end of the anti-blocking pipeline is sealed and fixed to a dialysis section, the other end of the anti-blocking pipeline is communicated with the fluid filling deviceoutside the dialysis section, and the anti-blocking pipeline comprises an expansion bag positioned beside a dialysis hole and a flow pipe for communication with the expansion bag with the fluid filling device. The expansion bag is volumetrically inflatable when filled with the fluid. Compared with the prior art, the novel peritoneal dialysis catheter has the advantages of being ingenious in structure, good in anti-blocking effect, easy to insert in or extract out of a patient, good in operation safety and capable of achieving rapid postoperative recovery of the patient, can effectively solve the problem of deviation of the position of the dialysis catheter, can also well extract ascites in the abdominal cavity, and has more thorough dialysis effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, relates to a novel peritoneal dialysis catheter and a method for using the same. Background technique [0002] At present, the more effective treatment method for patients with renal function decline is dialysis therapy, which is a treatment method that allows the components in body fluid to be excreted from the body through a semipermeable membrane. [0003] Peritoneal dialysis is a dialysis method that uses the body's own peritoneum as a dialysis membrane. Its principle is to exchange solutes and water between the dialysate poured into the peritoneal cavity and the plasma components in the capillaries on the other side of the peritoneum to remove residual in the body. Metabolites and excess water, while supplementing the necessary substances for the body through the dialysate, through continuous renewal of the dialysate, to achieve the purpose of kidney replacemen...
