-15- Pump-Actuated Sequencing Valve and System Abstract A pump-actuated sequencing valve for sequentially administering, to a patient, two fluids contained in separate respective reser- voirs, wherein the fluid is pumped from a first one of the two reservoirs by means of a pump associated therewith. The valve comprises a first portion connected to the first reservoir, a second portion connected to the second reser- voir, and a third portion connected between the first and second portions, on the one hand, and the patient, on the other hand. The second por- tion includes a ball valve which is pressure- responsive to operation of the pump for blocking flow of fluid to and from the second reservoir, thus blocking both forward flow from the second reservoir and backflow from the sequencing valve toward the second reservoir. The sequencing valve is, preferably, employed in a pump-actuated sequencing system which includes a further valve disposed between the second reservoir and the second portion, and control means responsive to non-operation/operation of the pump for auto- matically opening/closing the further valve so as to permit/block flow of fluid from the second reservoir to the sequencing valve.
