Abstract: The present invention relates to a device for measuring physiological signals of an object, for instance a human body of a patient. The device is provided with measuring means for measuring the physiological signals and with signal processing means for at least partially processing the measured physiological signals. According to the invention the device (1) comprises a first housing part (2) to which the measuring means (4A-4F) are attached. The device also comprises a second housing part (3) in which the signal processing means are accommodated. The housing parts (2, 3) are electrically connectable by means of a releasable coupling.
