    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.

    Abstract: A power injector (10) is provided for injecting fluid from a replaceable syringe (40, 40a) and through an injection tube (50) into the body of an animal. The injector (10) is provided with one or more operator-removable and interchangeable syringe mounting heads (15), at least one of which mounts syringes of a rear loadable type. Preferably an alternative head is provided that accepts front loadable syringes. The mounting head (15) includes an openi ng (30) and a moveable syringe holder (32) that preferably pivots open to receive a syringe (40, 40a) from the back of the holder and pivots closed to orient the rear of the syringe (40, 40a) over the ram (12). The holder (32) has a slot (16a) therethrough having a width sufficient to permit an injection tube (50) attached to the syringe nozzle to be moved transversely through the slot (16a) to permit the syringe (40, 40a) to be removed from the holder without disconnecting the tube (50) from the orifice of the syringe (40, 40a) and without withdrawing the tip of the tube rearwardly through the opening. The holder (32) preferably includes a replaceable insert configured to snugly support a rear loadable syringe of a given configuration. One insert is preferably provided in the form of a pressure sleeve configured to support a syringe (40, 40a) during high pressure use. The head (15) has a locking mechanism (25) that locks the syringe (40, 40a) to the injector, couples the syringe plunger (48) to the ram (12), locks and releases the head (15) and locks the holder (32) in operating position.

    Abstract: A front-loading syringe which comprises a movable plunger for injecting liquid contrast media, is rotatably mountable on a front wall of an injector housing with an interference fit and in sealed relationship with respect thereto, with or without a pressure jacket, by a first-quick release mechanism. At the same time, the plunger is connected to an injector drive mechanism by a second readily releasable mechanism. During the mounting operation, a sensor reads injection information from an indicator device on the syringe and feeds it to an injector control. An audible-and-tactile indicating mechanism also is activated when the syringe is essentially in the desired mounted position. The syringe may include reinforcing ribs which also function as volumetric gradations, and liquid media presence-or-absence indicating dots which appear circular against a liquid media background and oval-shaped against an air background. An injection end of the syringe comprises an injector portion of reduced diameter inside a screw-threaded attachment portion of larger diameter, and may include loop-shaped reinforcing handle portions.

    Abstract: A front-loading syringe (22) which comprises a movable plunger (38) for injecting liquid contrast media, is rotatably mountable on a front wall (24) of an injector housing (26) with an interference fit and in sealed relationship with respect thereto, with or without a pressure jacket, by a first-quick release mechanism (28). At the same time, the plunger (38) is connected to an injector drive mechanism by a second readily releasable mechanism (42). During the mounting operation, a sensor (72) reads injection information from an indicator device on the syringe and feeds it to an injector control (68). An audible-and-tactile indicating mechanism also is activated when the syringe is essentially in the desired mounted position. The syringe (22) may include reinforcing ribs which also function as volumetric gradations, and liquid media presence-or-absence indicating dots (78) which appear circular against a liquid media background and oval-shaped against an air background. An injection end of the syringe comprises an injector portion of reduced diameter inside a screw-threaded attachment portion (82) of larger diameter, and may include loop-shaped reinforcing handle portions (92).
