The new Dopplex Assist bi-lateral package has been introduced to simplify the purchasing process. The package includes all the sensors, probes, electric pump and cuffs for rapid bi-lateral measurements of lower limb arterial and venous disease with the Dopplex AR2 software and cables now included. The Dopplex Vascular Assist package is configured as a single channel system for measurements using Doppler, PPG and PVR. The standard power source is the Electric Pump. It is ideal for comprehensive measurements in the primary and secondary care settings. It can also be configured as a bi-lateral unit by the addition of extra sensors and cuffs. The Dopplex Assist - Spectral Package allows the user to record Doppler waveforms and measure systolic pressures. Using the integral patient database the measurements can be stored and printed at a later date or at a different location.
