Description

Hemodialysis long-term catheter Technical Field The utility model relates to the technical field of medical appliances, in particular to a hemodialysis long-term catheter. Background Hemodialysis long-term catheter is a medical device for long-term hemodialysis treatment. It is mainly used for establishing vascular access for patients with renal failure and other patients who need long-term hemodialysis. Such catheters are typically made of flexible medical materials, with one end inserted into the central vein of the patient and the other end used externally to connect the dialysis machine. Compared with the temporary dialysis catheter, the hemodialysis catheter can be used for a longer time, and can ensure that a patient can perform hemodialysis stably for a longer time. In the process of using the hemodialysis long-term catheter, two branch pipes connected to the hemodialysis long-term catheter are exposed, and the situation that the two branch pipes are mutually wound easily occurs, so that the use of the hemodialysis long-term catheter is affected. Disclosure of utility model The utility model aims to provide a hemodialysis long-term catheter, which solves the problem that in the prior art, the two branch pipes are easy to intertwine.
