Claim 8:
9. A method of enabling medical fluid transfer between a source container and a destination container, the method comprising the steps of:
providing an electronic medical fluid transfer device comprising a computer processor, the computer processor being configured to control a first electromechanical driver and a second electromechanical driver;
providing a fluid transfer module comprising a multidirectional fluid control valve, the multidirectional fluid control valve comprising:
an inlet port,
an outlet port,
an intermediate pumping region, and
a rotatable driving interface being configured to interface with the first electromechanical driver;

instructing a user to removably attach the fluid transfer module to the electronic medical fluid transfer device;
providing one or more instructions or algorithms in the electronic medical fluid transfer device to enable the computer processor to:
position the multidirectional fluid control valve to provide a fluid pathway between the source container and the intermediate pumping region;
actuate the intermediate pumping region with the second electromechanical driver to draw medical fluid from the source container and into the intermediate pumping region; and

providing an electronic sensor being configured to detect if the medical fluid within the fluid transfer module comprises one or more regions of air, vacuum, or partial vacuum;
wherein the computer processor is configured to perform a purge process based upon information detected regarding the region of air, vacuum, or partial vacuum, and wherein the purge process comprises the steps of actuating the intermediate pumping region to return at least a portion of the medical fluid to the source container and then actuating the intermediate pumping region to draw medical fluid from the source container.
