Abstract
A device (1) for monitoring a vital sign of a living subject, comprising a measuring unit (2) for measuring at least one physical quantity indicative of said vital sign at an area (8) overlying an artery (7) of the subject, which measuring unit (2) is provided on a carrier (3) to be worn by the subject during operation, and a processing unit (4) for processing the measured physical quantity into a value for the vital sign, which device (1) is provided with at least one detector (5) for detecting the position of the measuring unit (2) relative to the artery (7) of the subject during operation and for actuating a feedback signal (Ufeedback) in dependence on this position. The user can move the device (1) relative to the artery (7) until the feedback signal (Ufeedback) is given, and thus a correct positioning of the measuring unit (2) relative to the artery (7) is achieved in an easy manner.
