Actuator apparatus for a prepackaged fluid processing module having pump and valve elements operable in response to applied pressures

Fluid processing apparatus for use in conjunction with a disposable flow module of the type including a housing having a bottom panel and at least one side panel, and a fluid-impervious sheet member within the housing overlying the bottom panel, the bottom panel including an outwardly depressed portion forming in conjunction with the overlying sheet member a fluid circuit, said fluid processing apparatus comprising:

• an actuator station for receiving and fixedly positioning said processing module housing;
• an actuator head within said actuator station arranged for movement between a position operatively engaging said bottom panel of said housing, and a position non-engaged to said bottom panel, said actuator head including at least one pressure actuator port;
• and
• means for establishing a pressure differential at said actuator port when said actuator head is engaged to establish fluid flow through said fluid circuit.
