Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a fixed headband for an intra-cervical double-lumen high-flow pipeline. Background Art

[0002] The blood in the body is drained out of the body and passed through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) 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, thereby removing metabolic waste from the body and maintaining electrolyte and acid-base balance. At the same time, the body's excess water is removed and the purified blood is returned. The entire process is called hemodialysis. During hemodialysis, the hemodialysis line is usually connected to the patient's vein through a double-lumen high-flow line.

[0003] When the existing intrajugular double-lumen high-flow tubing is in use, the lower end of the tubing is fixed by gluing, which causes the upper end of the double-lumen high-flow tubing to sag and move drastically, which can easily cause the patient's cannula to shift, bend, or even fall out, thereby affecting the quality and effect of hemodialysis.
