A hemodialysis professional nurse needs to evaluate the condition of the blood vessel of a patient in detail and select a proper internal fistula puncture method. The scientific and standard puncture method can reduce puncture complications, prolong the service life of the puncture method and improve the dialysis quality of patients. This requires that the hemodialysis room nurse must have a very hard technique for lancing, and the improvement of lancing technique can only be summarized by constant practice plus failed experience. For a novice nurse who just enters the hemodialysis room, it is impossible to take the patient as a practice and the puncture technique can only be improved by means of a training model.
