﹤Biotech & Biomed Innovation﹥Arteriovenous Fistula Inspecting Device
Kaohsiung Medical University / Prof. Wen-Hsien Ho
Pain Points Solved
- Conventional arteriovenous fistula stenosis assessment often relies on clinical experience or additional imaging examinations, which may delay the detection of vascular narrowing and interrupt scheduled hemodialysis treatments.
-
This technology utilizes artificial intelligence and acoustic blood-flow analysis to provide rapid, non-invasive screening before dialysis. With a diagnostic accuracy of 95%, it enables early intervention, reduces emergency procedures, and lowers healthcare burdens.
Technology Introduction
End-stage renal disease (ESRD) requires routine pathological examination to ensure dialysis fistula function. By measuring and recording arteriovenous blood flow before hemodialysis, quantifying minute features in blood flow sounds, extracting their acoustic characteristics, comparing them with normal blood flow sounds, and applying artificial intelligence methods, we then obtain the degree of vascular stenosis. The accuracy of the deep learning model reaches 95%. The device can be applied in the following areas:
1. Dialysis room for kidney dialysis patients.
2. Long-term care facilities for kidney dialysis patients.
3. Home care for kidney dialysis patients.

Application Examples
- The device can be deployed in hospital dialysis units and dialysis centers to routinely monitor arteriovenous fistula function before treatment, enabling early detection of stenosis and improving dialysis safety and quality.
-
It is also suitable for long-term care facilities and home-care settings, providing continuous fistula monitoring for ESRD patients and supporting remote healthcare management to reduce the risk of unexpected vascular occlusion.
