Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a wearable arteriovenous fistula monitoring device. Background Art
[0002] Arteriovenous fistula is one of the surgical operations, mainly used for hemodialysis treatment. Arteriovenous fistula is a minor vascular anastomosis operation. The artery near the wrist of the forearm and the adjacent vein are sutured so that arterial blood flows in the anastomosed vein, forming an arteriovenous fistula. This arteriovenous fistula is similar to an artificial blood vessel and is an extremely important lifeline for the patient. The blood vessels of the arteriovenous fistula can provide sufficient blood for hemodialysis treatment and provide guarantee for the adequacy of dialysis treatment. Therefore, medical staff often need to monitor the flow of the blood vessels of the arteriovenous fistula to determine whether the blood vessels of the arteriovenous fistula are flowing normally and the circulation situation. Once blockage or slow flow occurs, emergency treatment is required. However, after the patient returns home after dialysis, the patient does not have the corresponding home detection device, so the circulation situation of the arteriovenous fistula cannot be detected, which poses certain safety risks.
