Technical Field

The utility model relates to the technical field of catheter fixing, in particular to a hemodialysis catheter fixing device.

Background

Hemodialysis is one of the renal replacement therapy modes for patients with acute and chronic renal failure. The method comprises the steps of draining in-vivo blood to the outside of the body, passing through a dialyzer consisting of innumerable hollow fibers, wherein the blood and electrolyte solution (dialysate) with similar concentration of the body are in and out of the hollow fibers, and carrying out substance exchange by dispersion/convection to remove metabolic wastes in the body and maintain the balance of the electrolyte and acid and alkali; at the same time, the whole process of removing excessive water from the body and reinfusion of the purified blood is called hemodialysis.

The catheter fixing device is generally used for fixing and limiting a catheter used for dialysis in hemodialysis, and the currently used catheter fixing device generally uses adhesive tape to adhere the catheter to the skin of a patient, but the method cannot be used when the skin is allergic to the adhesive tape, and when the catheter is pulled, the catheter is bent, so that the hemodialysis process is influenced.
