ABSTRACT:
A fluid-transfer system has two pistons movable within a barrel so that the ends of the piston faces can move together or apart, the barrel having at least two openings therein for transfer of fluid into and out of said barrel. The pistons can be controlled manually, mechanically or by computer to draw fluid from one or more reservoirs into the barrel and transfer the selected fluid in selected quantity into a chamber for storage or for reaction or analysis. The system is particularly useful for transfer of fluid from a selected chamber to another selected chamber, for mixing fluids, and for carrying out multiple tests on blood taken from a patient or from a plurality of patients under the control of a computer, which can accept programs for carrying out specific procedures.
