A mains-electricity (AC-powered) device intended to interface between an air compressor and a vascular cuff to regulate rapid inflation of the cuff during procedures to assess vascular health (e.g., venous insufficiency, maximum venous outflow, arterial inflow). Intended to be used by a healthcare professional in a clinical setting, it consists of a compact unit with display/controls, pressure regulator, and tubing to connect to the cuff. It is intended to regulate inflation to a preselected target pressure, to maintain that pressure, and subsequently deflate the cuff; it may be intended to be used with a timer for automatically-triggered inflation.
