Fluid Mixing Control Device for a Multi-Fluid Delivery System
First Claim
1. A fluid delivery system for use in medical procedures to deliver multiple injection fluids to a patient, comprising:
- a first pump device for delivering a first of the multiple injection fluids to the patient;
a second pump device for delivering a second of the multiple injection fluids to the patient;
a control unit controlling the first pump device and the second device;
an interactive visual display electronically linked to the control unit for a user to select discrete mixture ratios 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 first pump device and the second pump device, comprising;
a housing; and
an actuator associated with the housing and controlling discrete flow rates of the selected discrete mixture ratios of the first and the second of the multiple injection fluids to the patient; and
wherein selection of a discrete mixture ratio by a user 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, andwherein 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.

Abstract
A fluid delivery system for use in medical procedures includes multiple fluid pump devices to deliver multiple injection fluids to a patient. The system includes a control unit controlling the fluid pump devices. An interactive visual display may be provided and electronically linked to the control unit so a user may select discrete mixture ratios of the first and the second of the multiple injection fluids to be delivered to the patient. A manual control device is operatively associated with the fluid pump devices and includes a housing and an actuator associated with the housing. Actuation of the actuator controls discrete flow rates of the selected discrete mixture ratio of the first and the second of the multiple injection fluids to the patient.
