AI Technical Summary

Technical Problem

The existing nephrology peritoneal dialysis tubes are prone to blockage due to the deposition of proteins, blood components and minerals on the tube wall. The existing removal methods are highly dependent on drugs, complex operations, and cannot prevent the removal of early microscopic deposits.

Method used

A nephrological peritoneal dialysis tube anti-blocking device is designed. The built-in propeller blade rotation shaft forms a directional vortex to accelerate the flow of liquid, and is equipped with a synchronous rotation of brush ring to remove sediment. The micro motor drives the rotation shaft to rotate to achieve the main animal cleaning and removal of clogging.

Benefits of technology

Effectively prevent proteins, blood components and minerals from precipitating on the tube wall, simplify the operation process, preventively remove early sediments, reduce the risk of catheter blockage, and improve treatment safety and reliability.

Abstract

The invention relates to the technical field of peritoneal dialysis in the nephrology department, and discloses a peritoneal dialysis catheter anti-blocking device in the nephrology department, the peritoneal dialysis catheter anti-blocking device comprises a peritoneal dialysis catheter, an inflow tube and an anti-blocking mechanism are fixedly installed outside the peritoneal dialysis catheter, a rotating shaft is rotatably connected to the interior of a drainage tube, and propeller blades are fixedly installed outside the rotating shaft. An equipment box is fixedly mounted on the right side of the drainage tube, and a micro motor is fixedly mounted in the equipment box. According to the anti-blocking device for the peritoneal dialysis catheter in the nephrology department, when the micro motor drives the rotating shaft to rotate, the propeller blades slowly stir dialysate in the peritoneal dialysis catheter, and a directional vortex is formed; according to the design, liquid flowing is accelerated, protein, blood components and mineral substances are effectively prevented from being adsorbed or precipitated on the tube wall, the problem of blockage caused by standing is solved, meanwhile, the process does not need to depend on drugs, the operation process is simplified, early-stage tiny sediments can be preventively removed, and the catheter is kept unobstructed.
