Background

A long-term central venous catheter for dialysis is one of the life lines of hemodialysis patients. The central venous catheter is easy to cause catheter intracavity infection. The mechanism of infection is mainly that staphylococcus aureus at the skin part is attached to the opening part of the catheter and migrates to cause the colonization of the lumen, and the infection is caused by the hemodialysis later, which is very easy to cause the fatal complications of bacteremia, leukemia, lung abscess, infective endocarditis, and the like. For the treatment, the focus is prevention, which can only enhance the disinfection of skin and catheter ports, and only pull out the catheter or replace the catheter in situ when infection occurs, which brings great economic burden to patients and national medical insurance.

The existing catheter only uses a heparin cap after dialysis is finished, the interval between the end of the dialysis and the next dialysis is 3 days, and no barrier for preventing infection exists in the three days except for a sterile dressing wrapped outside the catheter, so that bacteria such as staphylococcus epidermidis and the like can not be effectively prevented from entering the catheter through a catheter port, and further catheter infection is caused.
