Injector
First Claim
1. In combination, an injector comprising a drive ram bidirectionally movable along a longitudinal axis, a motor drivingly coupled to said drive ram to selectively advance and retract said drive ram along said axis, and a syringe mount having a syringe engaged in such manner as to position said syringe relative to said injector to permit said drive ram to move a plunger of said syringe within and relative to a body of said syringe;
- anda hanger configured to support said injector and including a heating element wherein said injector may be operatively connected to said hanger in such manner that any syringe engaged to said syringe mount is in confronting relationship with said heating element and said injector being detachable from said hanger for use in an injection procedure.

Abstract
An injector 20 that may be used to deliver radiographic contrast media and/or flushing solution into a patient'"'"'s vascular system for the purposes such as obtaining enhanced diagnostic x-ray images. The injector includes the following features: (1) a syringe mount 26 for attachment of a syringe 28 to the injector 20; (2) display 34 and controls 90 for volume and flow rates; (3) automatic limiting of the operating pressure of the injector 20 as determined by the selection of a flow rate; (4) a syringe cradle 48 having a warming capability; (5) a purge/retract trigger 36 for control of the injection procedure having intuitive direction (i.e., forward for injecting, reverse for filing), non-contact control transmission through the housing of an injector 20 for an improved seal integrity, a speed lock, and/or the ability to change the concentration and/or flow rate of media or other fluid during an injection procedure; (6) a switch to determine when the drive ram 46 is in a “home” position; (7) a “soft” on/off power switch separate from the injector; and (8) a structure to prevent rotation of the drive ram 46 about its axis of symmetry 76. Additionally, the injector system includes software for the control of various components.
