What is a handheld Doppler used for?

Introduction

A handheld Doppler device, commonly referred to as a Doppler ultrasound, is a critical tool in medical diagnostics. It leverages the Doppler effect to measure the movement of objects, primarily blood within arteries and veins, using sound waves. This article elucidates the principles, applications, and specific solutions offered by Leis Company.

Principles of Handheld Doppler

The handheld Doppler device operates on the Doppler effect principle, where the frequency of sound waves changes relative to the motion of an object. These devices typically emit ultrasound waves in the range of 2 to 10 MHz. As sound waves reflect off moving blood cells, the frequency shift is measured, allowing for the determination of blood flow velocity.

Applications in Medical Diagnostics

Handheld Dopplers are predominantly used in the following medical diagnostic applications:

1. Fetal Heart Monitoring

In obstetrics, handheld Dopplers are frequently used for monitoring the fetal heartbeat. These devices offer a non-invasive means to assess fetal health, crucial during prenatal visits.

2. Vascular Health Assessment

Handheld Dopplers evaluate blood flow in peripheral arteries and veins, aiding in the diagnosis of peripheral artery disease (PAD) and venous insufficiency. This is vital for patients with diabetes or those at risk of vascular complications.

3. Cardiovascular Examination

These devices aid in identifying abnormal blood flow patterns, which can indicate conditions like valvular heart diseases or congenital heart defects. Doppler readings provide data on flow velocities, aiding in comprehensive cardiac assessments.
