Abstract
Accurate manual adjustment of a desired delivered flow rate in an intravenous liquid injection system is expedited and simplified. A programmable counter, fed by a pulse train of known repetition rate, is pre-set in accordance with the volume of liquid to be delivered, the size of the individual liquid drops, and the desired length of time during which the liquid is to be delivered. The counter provides a pulsed visible and/or audible indication at the drip rate determined by the pre-set conditions. The operator, upon comparison of the actual drip rate with the pulsed indication rate, can readily adjust the drip rate to coincide with the indications. The apparatus may include a pulse per unit time readout capability.
