Abstract:
Process for the measurement of the aggregation of blood platelets or the coagulation of blood, in which process the blood flows through an aperture (29), containing a part (28), whereby the clogging of the aperture is measured, characterized in that the drop in pressure (.DELTA.P) occurring during the clogging is measured at specific time intervals (dt) at the aperture (29), and the volume flow (I) is changed in such a manner that it corresponds to a predetermined function, which simulates the flow resistance (R.sub.v) of a capillary, preceding the aperture (29), or that during the predetermined time interval (dt) the pressure (.DELTA.P) is held constant and thereafter, when the volume flow (I) has decreased by an amount, is readjusted until it matches the function.
