FLUID INJECTION SYSTEM FOR CORONARY INTERVENTION

摘要

A fluid injection apparatus and method of injecting fluid are disclosed. The apparatus includes a control syringe electrically connected to a power- acutated syringe. A sensor is provided proximate the control syring to monit or of the plunger therein, with a signal representative of plunger position the n being communicated to a processor for calculation of a corresponding control signal. The control signal is received by an actuator of the power-actuated syringe to move the plunger of the power-actuated syringe is a manner relate d to movement of the control syringe. The control syringe is provided with a feedback device to provide the operator with an indication as to the pressur e of the fluid being injected into a patient.
