Background
The current prerequisite for long-term hemodialysis is the establishment of a stable and effective vascular access that can be relied on as a life line for hemodialysis patients. For patients who have serious illness and cannot tolerate operation, have poor cardiac function and cannot tolerate arteriovenous internal fistula shunt, or need to use a transition passage for dialysis in the mature period of the arteriovenous internal fistula, implanting a semi-permanent dialysis catheter through an internal jugular vein is a better choice.
The dialysis catheter is applied to clinic since 1960, and the technology is mature at present. Compared with a temporary catheter, the semi-permanent dialysis catheter has the advantages of low infection risk, long-term use, reduction of hospitalization time and the like; compared with arteriovenous internal fistula and artificial blood vessel transplantation, the artificial blood vessel fistula has the advantages of being capable of being used quickly, not increasing cardiac load, not causing puncture pain and the like. However, at the same time, the semipermanent dialysis catheter has a serious defect that the external connecting tube is always hung on the body surface of a patient, and the catheter is large in size and cannot be detached; and when some special cases, for example; 1. after a patient dies, the pipeline needs to be pulled out due to the requirement of a part of family members on the integrity of the remains of the patient, but the clinical semi-permanent catheter needs to be pulled out by two doctors, and if the catheter is pulled out at night, only one on-duty doctor is difficult to complete the operation; and the whole removal wound is large, if DIC occurs, the semi-permanent catheter tunnel continuously seeps blood and is difficult to press, and the chest hematoma affects the beauty; 2, when an external connecting pipe is polluted or the integrity is damaged, the semi-permanent catheter is communicated with a deep vein, so that the risk of blood infection is extremely high, systemic bacteremia, sepsis, infective endocarditis and even infective shock occur, and the patient has poor prognosis and even dies due to infection. In view of the defects, the device is simple to operate, can conveniently clamp the catheter in time, further resists infection or pulls out and changes the catheter and other operation nursing, ensures the sealing property and integrity, and finally greatly expands the use safety of the semi-permanent dialysis catheter.
