Clinical Evaluation Study of a Device for Detecting Arteriovenous Fistula Vascular Function

Recruiting

• Conditions: Early Detection of Complications of Arteriovenous Fistula; Voiceprint; Arteriovenous Fistula Flow Monitoring

• Registration Number: NCT05531825
• Lead Sponsor: Ai Peng

Brief Summary

Evaluation on the reliability, practicability and safety of a wearable device for measuring arteriovenous fistula function based on voice print.

Detailed Description

Arteriovenous fistula is the lifeline of maintenance hemodialysis patients. At present, there is a lack of a simple wearable real-time evaluation technology and device for arteriovenous fistula, which can help doctors find and deal with the complications of arteriovenous fistula timely and accurately. This study proposes an innovative design based on PVDF piezoelectric membrane by combining all kinds of technologies including NB-iot/4G transmission mode to realize real-time monitoring and feedback of the health status of arteriovenous fistula vessels, so that the use time of arteriovenous fistula can be prolonged and the survival rate of dialysis patients can also be improved.
