An apparatus for monitoring one or more human physiological functions such as pulse rate, body temperature and body hydration levels is disclosed. In particular, a pulse monitoring apparatus is disclosed which is incorporated in a wristwatch (10). The apparatus comprises an ultrasonic transducer assembly (12) which measures blood velocity in the radial artery utilising the doppler effect and provides output signals which are processed by processing circuitry (35) to give an output which is utilised to indicate the pulse rate on a watch display (37) in place of or in addition to a time display. The ultrasonic transducer assembly (12) is attached to the wrist band (13), and is moveable along the latter relative to the indicating assembly (11) for accommodating wrists of differing size. |
