1. A device for performing repeated measurements and tracking of a distinctive blood pressure level in a blood vessel in a body part, wherein the device comprises,a pressure control unit for controlling a pressure providing device to apply an external pressure to the body part,a detector unit for detecting appearance of a physical characteristic indicative of the distinctive blood pressure level, whereinthe device is configured to:

  • (i) control the pressure control unit to change the external pressure in a first direction until the physical characteristic has been detected;

    (ii) in response to the detection of the physical characteristic, measure the external pressure between the body part and the pressure providing device by use of a pressure sensor connected to the pressure providing device so as to provide a measure of the distinctive blood pressure level;

    (iii) in response to the detection of the physical characteristic, control the pressure control unit to change the external pressure in the direction opposite to the first direction until the physical characteristic is no longer detected; and

    (iv) cyclically repeat (i), (ii) and (iii) to produce a signal that tracks the distinctive blood pressure level over time.
