Fluid mixing control device for a multi-fluid delivery system

摘要

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.

1. A fluid delivery system for use in medical procedures to deliver multiple injection fluids to a patient, the system 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 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 first pump device and the second pump device, the manual control device comprising:
a housing; andan 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.
