The BV-520E Vascular Doppler is a handheld 8MHz digital ultrasonic blood-flow detector designed for non-invasive assessment of peripheral arterial and venous blood flow. Its 8.0MHz Doppler probe detects vascular blood-flow signals and provides blood-flow velocity measurements, making the compact device suitable for peripheral vascular assessment in clinical and professional healthcare environments.
The BV-520E uses an 8.0MHz ±10% ultrasonic Doppler frequency to detect blood-flow conditions in peripheral vessels. The device can assist trained healthcare professionals in distinguishing arterial and venous flow through characteristic Doppler sounds and evaluating blood-flow velocity.
Its compact design, rechargeable lithium-ion battery, built-in speaker, and 2.4-inch display make the BV-520E digital vascular Doppler convenient for portable examinations.

Clear Arterial and Venous Blood-Flow Signals
The BV-520E assists trained professionals in differentiating arterial and venous blood-flow signals by their characteristic acoustic patterns.
Arterial flow generally produces a stronger, rhythmic Doppler sound with cyclical peaks and valleys, while venous flow tends to produce a softer and more continuous sound pattern. The device’s audio output and signal display help the operator evaluate detected vascular signals during examination.
Important:Â
The BV-520E is intended for use by appropriately trained healthcare professionals. It should not be used as a substitute for clinical diagnosis or other required diagnostic testing.

Clinical and Professional Applications
Vascular Surgery
The BV-520E can assist healthcare professionals in evaluating peripheral vascular blood-flow signals when assessing conditions involving limb vessels. It may be used to help identify changes associated with arterial narrowing or obstruction and to monitor peripheral venous blood-flow characteristics.
Cardiothoracic Surgery
The handheld Doppler can assist with locating peripheral blood vessels and evaluating detectable blood-flow signals during relevant clinical procedures.
Burn and Plastic Surgery
The device can be used for peripheral vascular assessment before and after procedures involving tissue or flap transplantation, helping trained professionals evaluate detectable vascular reperfusion signals.
Orthopedic and Trauma Surgery
The BV-520E can assist in checking detectable blood-flow signals following vascular anastomosis procedures involving the limbs.
Microsurgery
For microsurgical procedures involving fingers and toes, the device can be used to assess blood-flow signals and vascular anastomosis conditions before and after surgery.
Urology and Andrology
The BV-520E can be used by qualified professionals to evaluate blood-flow velocity signals from penile arteries as part of appropriate clinical vascular assessment.
