Pulsatile fluid pump system

A pulsatile fluid pump system comprising:

• a pump-valving assembly including a chamber and a set of ports;
• a diaphragm assembly coupled to the chamber and including an edge-mounted flexible diaphragm;
• wherein the diaphragm assembly and the pump-valving assembly are configured (i) as an integral pump assembly surrounded by a flange having a pair of opposed sides and (ii) to implement pumping when the diaphragm assembly is reciprocated in an axial direction;
• a control housing configured to removably and slideably receive the integral pump assembly on an exposed surface of the control housing and to couple to the integral pump assembly when the integral pump assembly is caused to slide along the exposed surface of the control housing in a direction transverse to the axial direction, the control housing including:
• a channel having a pair of opposed sides configured to receive the flange when the control housing is slideably coupled to the integral pump assembly, and to prevent rotation of the diaphragm assembly while the control housing is coupled to the integral pump assembly;
• a push rod configured to removably and slideably couple mechanically to the diaphragm assembly when the control housing is slideably coupled to the integral pump assembly;
• a linear motor coupled to the push rod and configured to reciprocate the push rod in the axial direction;
• and a controller system electrically coupled to the linear motor and configured to cause a desired operation of the linear motor.
