Arm Phantom Set

The Arm Phantom Set is a replica model of a human arm with ultrasonic Doppler probe and phantom fluid for simulating blood, enabling Doppler sonographic examinations of blood vessels. The model features a variety of tubing (simulating blood vessels), including one tube which simulates a blood vessel stricture or stenosis. When used in tandem with compatible equipment, examinations typical of those used in vascular diagnosis can be simulated. Doppler spectra are measured for the flow through arteries and veins with both a pulsing flow (like a heart beat) and continuous flow, allowing sounds typical of Doppler sonography to be heard. Changes in the spectra and the Doppler sound due a stenosis (stricture) in the elbow can be demonstrated, and when used with a pulsing flow, the calculation of the flow index and resistance index are possible with this replica model.
