ABOUT THIS PRODUCT:
This set-up shows how blood flow studies are performed using Doppler ultrasound (Doppler sonograph). On a realistic arm dummy, the differences between continuous (venous) and pulsating (arterial) flow are shown as well as the difference in flow through a normal blood vessel and a stenosis.
Benefits: • Ideal experiment for medical students to learn the principles of Doppler sonography
• True to life with an arm model with blood vessels and stenosis
• Experiment components can also be used for other experiments relevant for medical students
• Display of measurement values as with a diagnostic system
Tasks: • Analyze blood flow and search positive and negative flow components. Explain the differences.
• Locate the built-in stenosis and compare the spectral distribution upstream and downstream of the stenosis.
• Examine and compare the three pulse modes of the pump.
