Problems solved by technology

Since the hemodialysis catheter needs to be fixed on the patient for a long time, the connection tube is relatively short for convenience. However, when the patient is undergoing hemodialysis, the short connection tube often affects the fixation of the hemodialysis catheter. In severe cases, the insertion port may be infected. bring pain to the patient

Abstract

A hemodialysis catheter comprises a catheter body, a connection seat, a fixing clamp, two extension pipes, catheter clamps, extension pipe connectors, lengthened fixing pipes, heparin caps and a tip end. The hemodialysis catheter is characterized in that the lower end of the catheter body is the tip end, the upper end of the catheter body is connected with a single hole formed in the lower end of the connection seat, and two holes formed in the upper end of the connection seat are connected with the two extension pipes respectively; the catheter clamps are arranged on the extension pipes, the extension pipe connectors are arranged at the other ends of the extension pipes, and the extension pipes are connected with the lengthened fixing pipes through the extension pipe connectors; the heparin caps cover the other ends of the lengthened fixing pipes. The hemodialysis catheter has the advantages that operation is convenient, firmness is good, safety and reliability are achieved, the lengthened fixing pipes externally connected with a dialysis pipeline can be frequently changed, fixing of the hemodialysis catheter can not be affected, the possibility of infection of an insertion opening can also be lowered, the condition that the extension pipes are damaged in the dialysis process and need to be replaced is avoided, and the pain of a patient is relieved.

Description

Technical field: [0001] The invention and a hemodialysis catheter belong to the technical field of medical instruments. Background technique: [0002] With the increasing number of maintenance hemodialysis patients and the continuous extension of life expectancy of hemodialysis patients, long-term hemodialysis catheters have gradually become one of the commonly used vascular access for hemodialysis patients, and their clinical application is becoming more and more extensive. At present, known hemodialysis catheters are mainly composed of venous catheters, three-way connectors, fixing sleeves, connecting tubes, plastic clips, connecting pipe joints, and connecting pipe joint caps. Since the hemodialysis catheter needs to be fixed on the patient for a long time, the connection tube is relatively short for convenience. However, when the patient is undergoing hemodialysis, the short connection tube often affects the fixation of the hemodialysis catheter. In severe cases, the ins...
