Background Arteriovenous fistula is an arteriovenous internal surgical operation and is mainly used for hemodialysis treatment. An arteriovenous fistula is one of surgical operations, is mainly used for hemodialysis treatment, is a minor operation of vascular anastomosis, and is characterized in that an artery close to a wrist part of a forearm and an adjacent vein are sutured, arterial blood flows in the anastomosed vein to form an arteriovenous fistula, and blood vessels of the arteriovenous fistula can provide sufficient blood for hemodialysis treatment and guarantee for the sufficiency of dialysis treatment. An arteriovenous internal fistula is a life line of a patient with renal failure, and the smoothness of the internal fistula directly determines whether the patient with renal failure is successful in dialysis and the quality of the dialysis. Before making hemodialysis, a patient with renal failure usually needs to rely on a medical staff to assist in judging the patency condition of the arteriovenous fistula through a common stethoscope, and the larger the vascular tremolo smelled by the arteriovenous fistula, the better the patency is. Because the auscultation position of the common stethoscope is planar, the laminating degree with the wrist of a patient is lower, the audible vascular tremolo is smaller or the vascular tremolo is not heard, so that medical staff can not timely grasp the condition of the arteriovenous fistula, further treatment of the patient is prevented, meanwhile, the arm thickness condition of each patient is different, and the laminating degree needs to be adjusted according to the condition of each patient so as to meet the auscultation requirements of different patients.
