The main advantages of central venous catheter are: 1. It is the lifeline of hemodialysis patients; 2. It is a transitional measure before internal fistula establishment and internal fistula embolism or infection; 3. It is a temporary access for emergency dialysis patients; 4. It is a temporary access for peritoneal dialysis patients after peritoneal infection.
[0003] At present, in the blood purification standard procedure, for patients using central venous catheter, two nurses operate respectively. After investigation, in actual operation, many dialysis centers have difficulty in double operation, which greatly increases the risk of catheter infection. When performing hemodialysis treatment, the connection head of central venous catheter and hemodialysis pipeline is wrapped and fixed with sterile gauze. However, the sterile gauze is opaque, and when the connection head of central venous catheter and hemodialysis pipeline bleeds, it cannot be found in time. Moreover, the sterile gauze needs to be manually wrapped by nurses. Due to observation needs, nurses need to frequently open the gauze, which is complicated to operate. In addition, it is easy to cause wear of catheter scale mark, and cannot guarantee the accuracy of heparin dosage when sealing the tube.
[0004] Therefore, a catheter fixer for hemodialysis is proposed to solve the existing problems. UTILITY MODEL CONTENT
