    Abstract: An animal fluid injector, replaceable syringe and method of replacement of the syringe in the injector are provided in which the syringe is loadable and unloadable into and from the injector through the open front end of a pressure jacket of the injector, thereby permitting replacement without retraction of the syringe plunger drive or disconnection of the injection tubing. The syringe is provided with a pressure restraining front end, such as an integral or removable cap with structure such as threads that lock the syringe to the front end of the jacket by mating with threads on the jacket. A mechanism in the injector, which includes, for example, a key on cam ring operated by a lever with one hand of an operator, interacts with structure such asymmetrically spaced notches on the back end of the syringe to, for example, rotate the syringe and simultaneously translate or rotate a coupling on the syringe plunger into and out of engagement with the plunger drive in the injector.

    Abstract: A power injector is provided for injecting fluid from a replaceable syringe and through an injection tube into the body of an animal. The syringe includes one or more operator-removable and interchangeable syringe mounting heads, 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 includes an opening and a moveable syringe holder that preferably pivots open to receive a syringe from the back of the holder and pivots closed to orient the rear of the syringe over the ram. The holder has a slot therethrough having a width sufficient to permit an injection tube attached to the syringe nozzle to be moved transversely through the slot to permit the syringe to be removed from the holder without disconnecting the tube from the orifice of the syringe and without withdrawing the tip of the tube rearwardly through the opening. The holder 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 during high pressure use. The head has a locking mechanism that locks the syringe to the injector, couples the syringe plunger to the ram, locks and releases the head and locks the holder in operating position.

    Abstract: An animal fluid injector is provided with a syringe guide, preferably in the form of a pressure jacket, having an open front end through which a replaceable disposable syringe is loadable into and unloadable from, thereby permitting replacement without retraction of the syringe plunger drive or disconnection of the injection tubing. The injector is provided with structure, preferably in the form of thread sections, which mates with cooperating structure on the syringe, to connect and lock the syringe to the injector, preferably by rotational motion of, preferably, less than a full turn, of for example, 90.degree.. In the illustrated embodiment, the structure is at the front end of the guide or at the front periphery of a jacket to connect to threads on a pressure restraining front end of the syringe. A mechanism in the injector, which includes, for example, a key on cam ring provided with a lever that is preferably manually operable with one hand of an operator, interacts with structure such asymmetrically spaced notches on the back end of the syringe to, for example, rotate the syringe and simultaneously translate or rotate a coupling on the syringe plunger into and out of engagement with jaws provided of a plunger drive in the injector.

    Abstract: A contrast media injection system detects the absolute position of the syringe ram using a non-contact sensor. A series of magnets and Hall-Effect sensors may be used or an opto-reflective system. Illuminated knobs that are connected to the drive mechanism for the syringe ram rotate with the drive and provide visual feedback on operation through the illumination. Analog Hall-Effect sensors are used to determine the presence or absence of magnets that identify the type of faceplate being used. The faceplates include control electronics, connected to the powerhead through connectors, which may be interchangeably used by the two faceplates. The faceplate electronics include detectors for automatically detecting the capacity of pre-filled syringes. Additional features include using historical data to provide optimum pressure limit values during an injection protocol, a removable memory device for storing and transferring information such as injection protocols and injector statistics, and password protection of such protocols.
