Fluid mixing control device for a multi-fluid delivery system

摘要

The control device is used to control delivery of fluids from a multi-fluid delivery system during a medical injection procedure. The fluid delivery system includes an injector used to deliver injection fluids to a patient. The control device is operatively associated with the injector for controlling discrete flow rates of injection fluids delivered to the patient. The control device includes a housing, first and second actuators associated with the housing, and an electronic substrate disposed within the housing and having a conductive pattern. The first actuator is operatively associated with the conductive pattern. The conductive pattern includes a plurality of predetermined digital values corresponding to discrete flow rates of injection fluids to be delivered by the injector. The second actuator is operatively associated with the electronic substrate and initiates output signals to the injector corresponding to desired mixture ratios of the injection fluids to be delivered by the injector.

1. A fluid delivery system for use in medical procedures to deliver multiple injection fluids to a patient, comprising:
an injector for delivering a first of the multiple injection fluids to the patient; a fluid control device for delivering a second of the multiple injection fluids to the patient; and a manual control device operatively associated with the injector and the fluid control device, comprising:
a housing;a first actuator associated with the housing and controlling mixture ratios of the first and the second of the multiple injection fluids to the patient; anda second actuator associated with the housing and controlling discrete flow rates of the mixture ratios of the first and the second of the multiple injection fluids to the patient, wherein actuation of the first actuator initiates first output signals to a control unit to deliver the first and second of the multiple injection fluids in discrete mixture ratios of the first and the second of the multiple injection fluids to the patient, and wherein actuation of the second actuator initiates second output signals to the control unit to control the discrete flow rates of the discrete mixture ratios of the first and the second of the multiple injection fluids to the patient.
