Control device for a fluid delivery system
First Claim
1. A fluid delivery system for use in medical procedures, comprising:
- an injector for delivering an injection fluid to a patient; and
a control device operatively associated with the injector for controlling flow rates of the injection fluid delivered to the patient, the control device comprising;
a housing;
an actuator movably associated with the housing, the actuator comprising an actuating member comprising a left rail and a right rail that cooperate to define a generally rectangular-shaped receiving pocket therebetween and a contact roller movably connected to the actuating member, the contact roller comprising a roller rotatably mounted on an axle that is rotatably supported by and disposed between the left and right rails of the actuating member, the roller being formed of an electrically conductive resilient material; and
an electronic substrate mounted to the housing and adapted to be received within the generally rectangular-shaped receiving pocket defined by the left and right rails of the actuating member, the electronic substrate comprising a conductive pattern and the roller of the actuator being adapted to engage the conductive pattern when the actuating member of the actuator is actuated by a user;
wherein the conductive pattern comprises a plurality of predetermined digital values corresponding to discrete flow rates of the injection fluid to be delivered by the injector, such that when the actuating member of the actuator is actuated by the user and moved relative to the housing, the roller of the actuator engages with and sequentially accesses the digital values of the conductive pattern and transmits the digital values to the injector.

Abstract
The control device is used to control delivery of fluid from a fluid delivery system during a medical injection procedure. The fluid delivery system includes an injector adapted to actuate a syringe used to deliver the injection fluid to a patient. The control device is operatively associated with the injector for controlling discrete flow rates of injection fluid delivered to the patient. The control device includes a housing and an actuator associated with the housing. An electronic substrate is disposed within the housing and comprises a conductive pattern. The actuator is adapted for operative association with the conductive pattern. The conductive pattern includes a plurality of predetermined digital values corresponding to discrete flow rates of injection fluid to be delivered by the injector, such that when the actuator is actuated the actuator operatively associates with the conductive pattern for transmitting the digital values to the injector.
