Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a hemodialysis catheter fixing and anti-falling device. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and passes it through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution containing electrolytes at concentrations similar to those in the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection. This removes metabolic waste from the body, maintains electrolyte and acid-base balance, removes excess water from the body, and returns the purified blood. The entire process is called hemodialysis.

[0003] However, the existing hemodialysis catheter fixing and anti-falling device has the following disadvantages:

[0004] (1) During the dialysis process, the dialysis tube may fall off due to the insertion port being too long, which may reduce the dialysis efficiency;

[0005] (2) It is inconvenient to adjust the height of the dialysis tubing according to needs during use, resulting in poor flexibility of the device.

[0006] Therefore, the utility model provides a device for fixing and preventing a hemodialysis catheter from falling off. Utility Model Content
