Document Type and Number:

Japanese Patent JP2695879

Kind Code:

B2

Abstract:

A mechanical drive system for use in driving a disposable cassette containing a reciprocating fluid pump and active valves from a main pump unit. The system uses a single power module cam (580) to drive both the reciprocating pump and the valves to eliminate the possibility of a timing error between the operation of the reciprocating pump and the valves. The power module cam (580) has a cam groove (590) which drives a pump actuator (540) and a bottom can surface (592) which drives two valve actuators (620).
