The VasoGuard is a family of products designed for non-invasive peripheral vascular diagnostic testing. It uses Doppler probes and photoplethysmography (PPG) sensors positioned on the body to measure physiologic signals and report data to the interpreting clinician. The system consists of up to 10 independent pneumatic pressure channels, up to five PPG ports, up to three Doppler ports that support 4MHz and 8MHz continuous wave (CW) Doppler probes, and a touchless temperature sensor. Model V10: 10 Pressure Channels / 5 PPG / 3 Doppler
A graphic recorder designed for determining and registering volume variations in the extremities (legs/toes and/or arms/fingers) as modified by the circulation of blood through them. It typically consists of flow and/or volume sensors and transducers attached to an electronic unit, which processes the data and displays the results. It may operate using one of several methods including venous occlusion (pneumatic), photoelectric, electrical impedance, or strain gauge. The device is typically used in peripheral vascular diagnostic investigations [e.g., for deep vein thrombosis (DVT) or arterial occlusive disease].
