ABSTRACT:
For controlling the cuff pressure in a blood pressure measuring device, the volume flow between a pump for filling the cuff and a valve for emptying the cuff on the one hand and the cuff on the other hand is detected by a flow sensor whose output signal is integrated by means of an integration circuit for producing an actual volume value. A computer unit for controlling the pump and the valve produces the control signals on the basis of this volume value formed by integration as well as on the basis of at least one quantity representative of the pressure/volume dependence of the cuff pressure.
