Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a restraint device for the arm on the side of an arteriovenous fistula. Background Technology

[0002] Hemodialysis is a life-sustaining treatment for patients with kidney failure. Arteriovenous fistula (AVF) is currently the most commonly used and least complication-prone vascular access method recognized in clinical practice. Each hemodialysis treatment lasts for four hours, during which the arm on the side with the fistula must be immobilized. This is difficult to maintain even for conscious adult patients, let alone young children, elderly patients, and patients with mental disorders. If the arm is bent, there is a risk of hematoma and dislodgement of the puncture needle.

[0003] Currently, most arteriovenous fistula (AF) arm restraint devices designed for clinical use are simple protective restraint devices, only restraining the forearm and wrist, and posing a risk of compressing the AF. More complex restraint devices are quite heavy. How to ensure patient safety and comfort while also facilitating operation by medical staff during dialysis is an urgent clinical problem to be solved.
