1. An injection system for injecting fluid into a patient, the injection system comprising:
- a fluid delivery apparatus;
a fluid path structured to be disposed between the fluid delivery apparatus and the patient;
a control unit in communication with and operable to control the fluid delivery apparatus; and
a control mechanism in communication with the control unit, the control mechanism comprising a tactile feedback unit and a sensor that generates and sends a signal to the control unit, whereby the control unit controls the injection of fluid into the patient in proportion to the signal.

Abstract
This invention relates generally to the field of medical devices for delivering contrast media during medical diagnostic and therapeutic imaging procedures and more particularly, this invention relates to improved contrast media delivery systems and methods of use which allow adjustment of contrast media concentration and injection parameters either before or during an injection procedure to provide patient specific dosing of contrast media, thus decreasing the waste and cost of these procedures while increasing their efficiency.

40. An injection system for injecting fluid into a patient, the injection system comprising:
-
a fluid delivery apparatus;
a fluid path structured to be disposed between the fluid delivery apparatus and the patient;
a control unit in communication with and operable to control the fluid delivery apparatus; and
a control mechanism in communication with the control unit, the control mechanism comprising a sensor that generates and sends a signal to the control unit, whereby the control unit is programmed to control the injection of fluid into the patient in proportion to the signal, wherein the control mechanism further comprises a syringe, the sensor being formed on a cradle coupled to the syringe, and an actuator mechanism in communication with the sensor, the sensor senses movement of the actuator mechanism by an operator, and the signal generated by the sensor is proportional to the movement of the actuator mechanism. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59)
