An electrically-powered device intended to receive data relating to multiple vital physiological parameters [e.g., electrocardiogram (ECG), noninvasive blood pressure (NIBP), pulse rate, temperature, haemoglobin oxygen saturation (SpO2)] from an appropriate sensor, and wirelessly transmit the data to a parent device (e.g., monitor and/or an off-the-shelf computer/tablet) with appropriate software installed; it may in addition be intended to provide electrical energy to the connected probe/electrode.
