An electrically-powered device assembly designed for professional use in a clinical setting to spot-check (user-initiated) measure and display multiple patient physiological parameters [e.g., electrocardiogram (ECG), noninvasive blood pressure (NIBP), pulse rate, temperature, haemoglobin oxygen saturation (SpO2), blood glucose]; it has no continuous monitoring capability or programmable alarm features. 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, SpO2 probe, spirometer), and potentially in vitro diagnostic [IVD] analysers (e.g., clinical chemistry analyser, urine analyser).
