Problems solved by technology

[0003] Peritoneal dialysis is the main method of renal replacement therapy for children with renal failure. The volume of peritoneal dialysis for children is different due to their different body weights. Children’s dialysate is often perfused at 30-50ml / kg. At present, the specifications of peritoneal dialysis are limited, and there is no suitable for children. Various specifications; at present, peritoneal dialysis uses weighing method to calculate the amount of dialysate, and there are certain errors

Abstract

The invention provides a measurable peritoneal dialysis in-vitro connecting device, and relates to the technical field of tectorial membrane dialysis. The measurable peritoneal dialysis in-vitro connecting device comprises a perfusion tube, a liquid discharging tube, a peritoneal dialysis catheter connector and a discharged liquid collecting bag; both the perfusion tube and the liquid dischargingtube are connected with the peritoneal dialysis catheter connector; one end, far from the peritoneal dialysis catheter connector, of the liquid discharging tube is connected with a drainage liquid collecting bag; and a perfusion connector communicated with dialysate is arranged at the end, away from the peritoneal dialysis catheter connector, of the perfusion tube, a first metering container is arranged on the perfusion tube, and the two ends of the first metering container are communicated with the perfusion tube. The technical effect of small dialysate amount metering error is achieved.

Description

technical field [0001] The invention relates to the technical field of membrane-covered dialysis, in particular to a meterable external connection device 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. Solute moves to the side of low concentration (diffusion); water moves from the side of low osmosis to the side of high osmosis (osmosis). The peritoneal dialysis solution is constantly replaced to achieve the purpose of removing metabolites and toxic substances in the body and correcting water and electrolyte balance disorders. [0003] Peritoneal dialysis is the main method of renal replacement therapy for children with renal failure. The volume of peritoneal dialysis for children is different due to their different body weights. ...
