Description

Dialysis catheter structure for nephrology department

Technical Field

The utility model belongs to the technical field of medical instrument production, especially, relate to a nephrology dept is with dialysis catheter structure.

Background

Dialysis is a separation and purification technique that separates small molecules from biological macromolecules by the principle of diffusion of small molecules through a semi-permeable membrane into water (or buffer). Dialysis is a treatment method in which components (solutes or moisture) in a body fluid are discharged to the outside of the body through a semipermeable membrane, and is generally classified into hemodialysis and peritoneal dialysis. Dialysis is a form of kidney replacement therapy, primarily for uremic patients, where vascular access is first required. The blood and electrolyte solution with similar organism concentration are arranged inside and outside one hollow fiber through a dialyzer consisting of a plurality of hollow fibers, and the substance exchange is carried out through dispersion and convection, thereby removing the metabolic waste in the body and maintaining the balance of the electrolyte and acid and alkali; at the same time, the excess water in the body is removed, and the whole process of purified blood reinfusion is called hemodialysis.

As is well known, hemodialysis patient needs blood to complete dialysis under extracorporeal circulation when carrying out hemodialysis, the dialysis catheter is put into human blood vessel in the time of dialysis, blood is drained out, wherein it is more commonly used that, the femoral vein catheterization or internal jugular vein catheterization, the length of dialysis catheter is limited, sometimes the dialysis catheter needs to be connected when the distance between dialysis machine and sick bed is far away, the dialysis catheter that needs to be connected must be firm, even can not appear the fracture under the effect of external force, just so safety, can not influence the normal progress of patient's dialysis, but because most of present junctions only with threaded connection, because patient's activity or junction nurse is not screwed up when operating and is led to the junction to break off, lead to a large amount of hemorrhage, even endanger patient's life also takes place occasionally.

Therefore, the problem to be solved is urgently solved in the current stage!
