A mains electricity (AC-powered) device assembly, sometimes with a rechargeable battery, designed to electronically measure and display multiple patient physiological parameters [e.g., blood pressure, blood glucose, pulse rate, temperature, haemoglobin oxygen saturation (SpO2), and possibly calculate mean arterial pressure (MAP)] for intermittent spot-check measuring in the home. It typically includes a main analysis unit with a visual display, and ports for input of the system's measuring components (e.g., thermometer, blood pressure cuff, blood glucose meter) or external devices (e.g., USB cable). It may be used in a healthcare facility or in the home.
