Abstract
An electronic method and apparatus for evaluation of the quality of drop detection in apparatus for parenteral administration of medical fluids, wherein the waveforms of electrical signals representing drop flow detection are evaluated for conformity with both prescribed amplitude and time duration characteristics. Separate counters record the total number of drop events evaluated and the portion of the total which are determined to be non-conforming, and the latter counter triggers alarms if a predetermined limit is exceeded within a prescribed number of total events.
