Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical supplies, in particular to a neck catheter fixing device for long-term hemodialysis. Background Art
[0002] Hemodialysis (HD) 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 through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) containing a concentration similar to that of the body are exchanged inside and outside the hollow fibers through diffusion, ultrafiltration, adsorption and convection principles to remove metabolic waste from the body, maintain electrolyte and acid-base balance, remove excess water from the body, and return the purified blood. The whole process is called hemodialysis.
[0003] Hemodialysis can help patients with uremia to excrete toxins and excess water from their bodies. It is divided into long-term hemodialysis and temporary hemodialysis. For long-term hemodialysis, the internal jugular vein is the most commonly used catheterization location. It is simple to use and can be maintained for a long time, making it suitable for patients on long-term hemodialysis. The method of fixing the neck catheter is generally to wrap the tube head with gauze and then stick the tape on the patient. The tube needs to be disinfected before the dialysis operation. If the tape is fixed too tightly, it is not easy to open and the tube will be pulled. If the tape is fixed too loosely, the gauze will easily fall off and the tube head will be exposed. At the same time, the tube head of the long-term catheter is not firmly fixed, so the catheter will repeatedly go in and out with the patient's activities. For patients who are allergic to tape, the tape will cause an allergic reaction such as a rash. Utility Model Content
