Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] An angiopoietic stent for hemodialysis, such as Figure 1 to Figure 6 As shown, it includes a vein built-in stent 1 placed in the vein and a blood vessel protection sleeve 11 placed outside the vein. The blood vessel protection sleeve 11 is sleeved on the vein built-in stent 1. The first puncture hole 10 of the vascular protection sleeve 11 is provided with a second puncture hole 111 at the position facing the first puncture hole 10, and the blood vessel pro...

Abstract

The invention discloses a method for using an angioleakage-improved bracket for hemodialysis. The usage method includes the following steps: disinfection, implantation of a venous built-in bracket, implantation of a blood vessel protection sleeve, fixation, dialysis, and maintenance of the bracket. The use method of the improved stent of the present invention separates the arteries and veins, reduces the blood shunted from the arteries to the veins, reduces the pressure of the return venous blood vessels, and effectively prevents the expansion of some blood vessel segments; The vascular protection sleeve has a tooth-shaped structure, which can directly seal the venous incision, or simply suture it, and then use the protective sleeve to seal the venous incision; reduce the complexity of the doctor's operation and save operation time; The reserved fixed puncture hole, combined with the buttonhole puncture method and blunt needle application, can easily form a puncture fistula, which can not only reduce the damage to blood vessels caused by vascular puncture, but also reduce the pain of patients and the difficulty of vascular puncture for nurses.

Description

technical field [0001] The invention relates to a method for using a stent, in particular to a method for using an angioleakage stent for hemodialysis. Background technique [0002] Angiostomy is the use of vascular surgery to artificially establish a short circuit between arteries and veins. There are mainly two methods: autologous angiostomy and artificial angiostomy. The main purpose is to arterialize the veins to ensure blood flow. The dialysis process has sufficient blood flow and the convenience of vascular puncture. However, the existing technical operations also cause various complications during treatment, such as thrombosis, steal syndrome, non-thrombotic stenosis, hemangioma, swollen hand syndrome, and high-output heart failure. In view of the above problems, we provide a hemodialysis angiostomy method and stent application technology, which not only maintains the advantages of the original technology, but also reduces damage to blood vessels, effectively protect...
