Description

Hemodialysis pipe is applied ointment or plaster Technical Field The invention relates to the technical field of hemodialysis, in particular to a hemodialysis catheter application. Background Hemodialysis is a core treatment means for maintaining life of end-stage renal patients, and a central venous indwelling catheter is a clinical main hemodialysis vascular access and needs to be reserved in a body for a long time to ensure that dialysis treatment is continuously carried out. The hemodialysis catheter is applied as a key medical consumable for fixing an extracorporeal catheter, protecting skin puncture points and isolating external pollution, directly influences catheter retention safety, treatment continuity and comfort level of daily activities of patients, and is an indispensable matching product in clinical care of hemodialysis. The hemodialysis catheter application which is used conventionally in clinic mostly adopts an integral adhesive tape to directly attach the catheter on the surface of skin, and has the defects that the catheter is in direct contact with the skin to produce repeated grinding, so that discomfort and even damage to the skin are easily caused, the outer end of the catheter is free of a closed protection structure, the outer end of the catheter is exposed for a long time and is easily subjected to external collision and friction to cause interface damage or infection induction, the double-cavity catheter is not restricted by separation, the mutual contact and shaking are easy to shift and twist, and the adhesive surface of the application is stuck on a large area, so that pain is obvious during tearing. Disclosure of Invention The present invention has been made in view of the above-mentioned problems occurring in the prior art. In order to solve the technical problems, the invention provides the technical scheme that the hemodialysis catheter application comprises sterile cotton, an adhesive tape arranged on the outer wall of the sterile cotton and a sterile ring arranged on the outer wall of the sterile cotton and used for limiting a catheter, wherein the sterile ring is provided with two fixing patches arranged on the outer wall of the sterile cotton and a sterile sleeve arranged on the outer wall of the sterile cotton.
