Background

An arteriovenous internal fistula is an arteriovenous internal surgical operation which is mainly used for hemodialysis treatment, in particular to a small blood vessel anastomosis operation, wherein an artery at the position of a forearm close to a wrist and an adjacent vein are sutured, so that arterial blood flows in the anastomosed vein to form the arteriovenous internal fistula. The arteriovenous internal fistula blood vessel can provide sufficient blood for hemodialysis treatment, and guarantee is provided for the sufficiency of the hemodialysis treatment. The maintenance work after arteriovenous internal fistula puncture is particularly important: 1. after each dialysis, the gauze roll is pressed to stop bleeding for 15-20 minutes, and if no bleeding occurs at the puncture position, the pressing can be removed; a little blood seeps, the compression force is reduced, the compression is continued for 30-60 minutes, and the blood seepage condition can be continued to be prolonged. For patients with hypotension, the compression force should not be too large, and the compression time should not exceed 20 minutes. 2. After dialysis is finished for 24 hours, hot compress can be carried out on blood vessels at the punctured positions, and medicines for softening the blood vessels are used for protecting internal fistula blood vessels. 3. The internal fistula part can be worn on the wrist guard to protect the internal fistula, avoid colliding with, prevent internal fistula blood vessel excessive expansion simultaneously.

The existing fixator only fixes the arm of the patient to avoid movement, but in actual operation, the arm of the patient possibly moves involuntarily in a sleeping state, so that a dialysis pipeline on the arm of the patient is easy to be broken, and the patient can puncture the side limb to move to cause the puncture point to bleed and extravasate, so that the expected treatment amount cannot be finished, and the treatment effect is influenced.
