ABSTRACT:
A control apparatus for a parenteral administration set which includes a calibrated rate control clamp for determining the time period over which the contents of a standard supply container of physiological liquid is delivered. The clamp selectively constricts the tubing interconnecting the supply container with a patient and the constriction is correlated with a calibrated scale. A spring device is provided to assure that the constriction is removed responsive to loosening of the clamp. This provides for an easy and rapid setting of a given time period over which the known volume of the liquid in the supply container is infused into the patient.
