FLUID MIXING CONTROL DEVICE FOR A MULTI-FLUID DELIVERY SYSTEM
First Claim
1. A fluid delivery system for use in medical procedures, comprising:
- an injector for delivering multiple injection fluids to a patient; and
a control device operatively associated with the injector, comprising;
a housing;
a first actuator associated with the housing;
an electronic substrate disposed within the housing and comprising a conductive pattern, the first actuator adapted to operatively associate with the conductive pattern when actuated by a user; and
a second actuator associated with the housing and operatively associated with the electronic substrate;
wherein the conductive pattern comprises a plurality of predetermined digital values corresponding to discrete flow rates of the injection fluids to be delivered by the injector such that when the first actuator is actuated, the first actuator operatively associates with the conductive pattern and transmits the digital values to the injector; and
wherein actuation of the second actuator initiates output signals to the injector corresponding to desired mixture ratios of the injection fluids to be delivered by the injector.

Abstract
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.
