1. An administration device for administration of a liquid drug over an extended time period to a patient, comprising:

  • an administration unit;

    a housing that houses the administration unit, the housing being adapted to be carried by the patient over the extended time period;

    a controller unit adapted to control operation of the administration unit, the controller unit further adapted to receive an alarm triggering signal;

    an alarming unit that is coupled to the controller unit, the alarming unit adapted to generate an alarm signal on reception of the alarm triggering signal by the controller unit; and

    a patient state monitor that includes a motion-sensitive sensor unit, the motion-sensitive sensor unit being reactive on patient motion, the patient state monitor being adapted to process a sensor signal (SS) generated by the motion-sensitive sensor unit, and a counter unit adapted to generate the alarm triggering signal and to transmit the alarm triggering signal to the controller unit if processing of the sensor signal (SS) indicates a patient motion level is below a predefined motion level, the predefined motion level being defined by a length of time-periods without patient motion that can be expected for a conscious human.
