1. An electronic medical fluid transfer device comprising:
a fluid transfer module comprising a first inlet fluid connector, a second outlet fluid connector, and a pumping region;
a sensor configured to detect whether a region of at least one of vacuum, partial vacuum, or gas is present in the fluid transfer module;
an electromechanical driver configured to be mechanically linked to and control the pumping region according to an operational parameter, wherein the operational parameter comprises one of: speed of the electromechanical driver, or acceleration of the electromechanical driver; and
one or more computer processors configured to communicate electronically with the sensor and the electromechanical driver to:
determine the operational parameter based on a viscosity of medical fluid to be transferred; and
adjust the operational parameter based on output of the sensor.
