Abstract

Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a femoral vein catheter fixing device for hemodialysis. Background Art
[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. In order to avoid the pain of needle sticks for every dialysis, deep venous catheterization is usually used. Because the femoral vein has a large lumen, is far away from the atrium, is a positive pressure vein, has a high safety factor, has no important tissue structures around it, is less difficult to puncture, and has a high success rate, femoral vein puncture catheterization is often selected as a type of deep venous catheterization. Femoral vein catheterization is a catheterization method that inserts a catheter from the tip of the femoral vein into the central vein through puncture. Femoral vein catheterization can reduce the number of times the intravenous syringe punctures the vein, which is beneficial to protecting the patient's skin, and can reduce the stimulation of drugs on blood vessels, which is beneficial to the absorption of drugs. It is very suitable for patients who need long-term infusion or have more serious conditions.
[0003] However, the inventors of the present application have discovered through clinical research that the rear end of the main femoral vein catheter currently used in the market is connected to two catheters, one at the arterial end (red) and the other at the venous end (blue), which is not convenient for fixation in the femoral triangle. In addition, since the femoral vein catheter is left in place for a long time, it is easy to cause pressure damage on the patient's skin when left in place for a long time, thereby increasing the patient's pain. Therefore, there is an urgent need to improve this situation. Utility Model Content
