The deep venous catheter is also called a Central Venous Catheter (CVC), which is one of intravascular tubes and is placed in a large vein. It has four models of single cavity, double cavity, three cavity and four cavities. Deep venous catheters are widely used in clinical settings. For example, regular hemodialysis patient carries out 3 ~ 4 times weekly hemodialysis, to the poor patient that can not use arteriovenous internal fistula of some vascular elasticity, the pipe becomes its only lifeline of living, because interim ductus venosus patency, fixity are relatively poor, and life is short, and it is higher to take place the infection rate, so all use semi-permanent two-chamber dark ductus venosus to carry out hemodialysis treatment to regular dialysis patient clinically. Clinically, the dialysis catheter commonly used is a double-cavity deep venous catheter with a polyester sleeve, a catheter port is connected with a blood pipeline, threaded grooves are formed in the outer portion of the catheter port, blood traces are left on the catheter port after the catheter port is used, and after the catheter port is disinfected and wiped, a disposable plastic screw cap or a heparin cap is adopted to screw the catheter port in a spiral mode to prevent air from entering the catheter port.
Infection of deep venous catheters is one of the most common complications of maintenance hemodialysis, and the post-infection results severely threaten the health of patients, shorten the survival time of patients and reduce the quality of life of patients. Currently, the disinfection methods generally used in clinic are roughly divided into: an iodophor cotton swab wipes around the external thread of the pipe orifice, an alcohol cotton sheet wipes, a forceps clamp cotton ball wipes and the like.
