Background

Hemodialysis (HD) is one of the alternative treatments for the kidney of patients with acute and chronic renal failure. The blood and electrolyte solution (dialysate) with similar concentration of organism are arranged inside and outside one hollow fiber by draining the blood in vivo to the outside of the body through a dialyzer consisting of a plurality of hollow fibers, and the material exchange is carried out by dispersion/convection, thereby removing the metabolic waste in the body and maintaining the balance of electrolyte and acid-base; meanwhile, excessive water in the body is removed, and the whole process of purified blood reinfusion is called hemodialysis; the existing hemodialysis puncture needle has certain disadvantages when in use. Firstly, when a user carries out dialysis treatment, the user may need to stop dialysis midway due to special reasons, and generally adopted methods are that dialysis is stopped firstly, a dialysis needle is pulled out, and then a process of dialysis is carried out by inserting the puncture needle once after problems are solved, so that a lot of pain is brought to the user; secondly, the traditional hemodialysis pjncture needle adopts the sticky tape fixed at the fixed infusion blood transfusion, very unstable to, patient's frequency of using the dialysis treatment can be along with patient's health is higher and higher, often the user probably dialyses oneself in daily life, but the back is inserted to traditional hemodialysis pjncture needle, the user can be because worry that the syringe needle drops, dares not to remove the arm easily, can cause muscle soreness and other problems for a long time, these all bring certain influence for the user, for this reason, we provide a hemodialysis pjncture needle that has the fixing.
