Abstract
An apparatus for administering a volumetric flow of parenteral liquids into a patient's system, in which the quantity of liquid flowing into the system may be easily adjusted, is disclosed. The apparatus includes two separate hydrostatic head pressure systems. The first head pressure is from a container, through a metering device with an adjustable fixed orifice to a regulator located a fixed distance below the container. The second head is from the regulator, which is designed to prevent air flow through it, to the patient. Several embodiments of the metering device and of the regulator are disclosed.
