Abstract
A fluid flow control system includes a disposable cartridge which is receivable in a shifting carrier body portion of a control module. The disposable cartridge houses a disposable pump and a pressure transducer element which are fluidly interconnected by an internal fluid flow circuit formed in part by an elastomeric separating sheet within the cartridge. Following loading of the cartridge, shifting of the carrier body portion automatically results in a drive connection to the pump, the positioning of various flow control valves within the cartridge and the seating of the pressure transducer element to the control module. External flow lines are readily placed in fluid communication with the internal fluid flow circuit through exterior connection ports provided on the cartridge.
