Abstract: A pump set for use with a pumping apparatus includes tubing for carrying a liquid. A valve mechanism is mounted to the tubing between an inlet section and a pump engagement section. The valve mechanism includes a first port connected to the inlet section of the tubing, a second port connected to the pump engagement section of the tubing, and a valve disposed between the first and second ports. The valve includes a stem rotatably mounted within a stem holder. The stem includes a flow passage extending through the stem and having an open V shape whereby a narrow open end of the flow passage communicates with the first port and a wide open end of the flow passage communicates with the second port to place the inlet section of the tubing in communication with the pump engagement section of the tubing.

Abstract: An apparatus and method for delivering liquid to a subject using a pumping device of a flow control apparatus. The method includes recognizing a pump set including a liquid container with a volume of liquid mounted to the flow control apparatus whereby the pump set is positioned to be acted on by the pumping device to deliver aliquots of liquid through the pump set. Operation of the pumping device is initiated to draw a prescribed volume of the liquid from the liquid container for a duration of time. A single aliquot of the volume of liquid is delivered from the liquid container to the subject. Operation of the pumping device is paused for a predetermined period of time before delivering another single aliquot of the volume of liquid from the liquid container to the subject.
