Background

Hemodialysis is a common treatment method for treating patients with acute and chronic renal failure. Hemodialysis is to lead the blood of a patient out of the body through a puncture needle, a dialysis catheter and/or a blood path pipe, remove metabolic wastes in the blood through the dialysis of a hemodialyzer and then return the blood to the patient. In the process, blood circulates in an extracorporeal blood path tube and a dialyzer at the speed of 250-350 ml/min, as each hemodialysis treatment time needs 4-5 hours, the CRRT treatment time is longer, the blood path is a life line of a hemodialysis patient, the dialysis treatment of the patient using the internal fistula needs to puncture 2 needles per time, and the puncture part is the limb part of the patient, the fixation of the extracorporeal blood path tube, the puncture needle and the catheter is very important, if the blood path tube and the puncture needle or the central venous catheter cannot be fixed properly, the connection part of the blood path tube and the puncture needle or the central venous catheter is easy to be separated, so that a large amount of blood flows out of the blood path tube, and serious consequences are caused.

At present, the blood vessel is generally fixed on the skin, clothes or quilt of a patient by using a common medical adhesive plaster or other medical adhesive plasters clinically. The hemodialysis takes long time, generally 4-5 hours each time, and the fixed adhesive tape can be loosened by the patient during the activities such as turning over and the like in the dialysis process. Because the blood vessel is filled with blood, the blood vessel has a certain weight, and once the fixed adhesive tape is loosened, the blood vessel, the puncture needle or the dialysis catheter can be separated. Adverse events resulting therefrom occur occasionally, and serious persons may threaten the life of the patient. In addition, the conventional fixing means has the following problems: the adhesive plaster is easy to loosen due to the increase of the secretion of skin grease, the fixation is not firm, and the venous catheter is pulled; the adhesive substance on the adhesive plaster or the adhesive sticker is in direct contact with the catheter, often adheres to the catheter, is easy to adhere to dirt, dander and bacteria, is difficult to remove and increases the infection risk.
