Abstract

The invention provides a peritoneal dialysis external catheter structure convenient to use. The peritoneal dialysis external catheter structure convenient to use comprises a fixing piece attached to the abdomen of a patient; and the guide pipe structure comprises an installation pipe, and the installation pipe is installed in the fixing piece. According to the peritoneal dialysis external catheter structure convenient to use, by arranging the catheter structure, the abdomen of a patient is mainly connected with dialysis equipment, so that dialysate can be input into the body of the patient, the mounting tube is arranged on the fixing piece, and the fixing piece is effectively and tightly mounted at the abdomen of the patient through the fixing band, so that the patient can be conveniently and rapidly fixed. The catheter structure is stably mounted, so that the mounting tube and the access tube can move along with the movement of the body of the patient, the situation that the access tube falls off from the abdomen of the patient can be well avoided, meanwhile, the length of the catheter structure is kept unchanged, and the patient has a large movement range.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an easy-to-use external catheter structure for peritoneal dialysis. Background technique [0002] Peritoneal dialysis uses the characteristics of the peritoneum as a semi-permeable membrane to pour the prepared dialysate regularly and regularly into the peritoneal cavity of the patient through the catheter through the action of gravity. The solute moves to the low concentration side; the water moves from the low osmotic side to the high osmotic side, and the peritoneal dialysate is constantly replaced to achieve the purpose of removing metabolites and toxic substances in the body and correcting water and electrolyte balance disorders. [0003] When performing abdominal dialysis on a patient, it is necessary to use an external dialysis catheter to connect to the dialysis equipment. When the external dialysis catheter is used, one end of the external dialysis catheter is plugged in...
