Fluid mixing control device for a multi-fluid delivery system

A fluid delivery system for use in medical procedures to deliver multiple injection fluids to a patient, the system comprising:

• a powered fluid injector for delivering a first of the multiple injection fluids to the patient;
• a fluid pump device for delivering a second of the multiple injection fluids to the patient;
• a control unit controlling the powered fluid injector and the fluid pump device;
• an interactive visual display comprising a menu with a plurality of discrete mixture ratios, the interactive visual display electronically linked to the control unit for a user to select a single discrete mixture ratio of the first and the second of the multiple injection fluids to be delivered to the patient;
• and
• a manual control device operatively associated with the powered fluid injector and the fluid pump device, the manual control device comprising:
• a housing;
• and
• an actuator associated with the housing and controlling discrete flow rates of the selected discrete mixture ratio of the first and the second of the multiple injection fluids to the patient;
• wherein selection of the discrete mixture ratio by the user on the menu of the interactive visual display initiates an output signal to the control unit to deliver the first and the second of the multiple injection fluids in the selected discrete mixture ratio of the first and the second of the multiple injection fluids to the patient, and
• wherein actuation of the actuator initiates flow rate output signals to the control unit to control the discrete flow rates of the selected discrete mixture ratio of the first and the second of the multiple injection fluids to the patient.
