Patent ID: 7662124

Claim:
A device for injecting angiographic fluid into a patient comprising: an actuator assembly having an axially movable shaft; a receptacle axially aligned with and positioned adjacent to said actuator assembly, said receptacle sized to receive a syringe; a syringe insertable into said receptacle, said syringe having a movable plunger aligned with and engageable to said movable shaft when said syringe is located in said receptacle; a motor linked to said movable shaft such that energization of said motor causes motion of said movable shaft into and out of said syringe; a control system operably connected to said motor for causing movement of said movable shaft; said control system adapted to allow a user to select an injection routine from two or more injection routines, each of the two or more injection routines being dedicated to a different injection procedure for a vessel of a heart of a patient, said control system being further adapted to allow said user to input a numerical patient characteristic value; said control system having a control console, said control console having a selector for selecting one of said injection routines; said control system having a motor circuit directing the speed of said motor according to input data from said user; said control system including a remote switch device connected to said control system providing user input data to said motor circuit; and, said control system including a routine enabling operability of said switch device during injection of fluid into said patient so as to enable continuously variable changes to said motor speed during said injection according to manipulation of said switch by said user, wherein said control system automatically determines default injection parameters based upon (a) the injection routine selected by the user, and (b) the numerical patient characteristic value input by the user, and wherein said default injection parameters include at least one of a flow rate limit, a volume limit, a maximum rise time and a pressure limit, said limits being automatically determined as a function of said numerical patient characteristic value and said selected injection routine.
