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 injection end of the syringe may include loop-shaped reinforcing handle portions.

    摘要: 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.

    摘要: A method of dispensing a hazardous pharmaceutical comprising the steps of: connecting a source of flushing fluid to a first port of a fluid delivery set; connecting a pressurizing unit of a powered injector system (including a powered injector and the pressurizing unit) to a second port of the fluid delivery set; purging air from the fluid delivery set; and, after purging air from the fluid delivery set, connecting a third port of the fluid delivery set to a source of the hazardous pharmaceutical. The fluid delivery set can, for example, include a valve system or assembly to control flow of fluid through the fluid delivery set. A system for delivery of a hazardous pharmaceutical includes: a syringe in operative connection with a powered injector; a protective container to enclose the syringe during operation thereof; the protective container being adapted to protect personnel from detrimental effects of the pharmaceutical; at least one source of flushing fluid; a fluid path adapted to connect to a patient; at least one source of the pharmaceutical; and a fluid delivery set including a valve assembly to which the syringe, the source of flushing fluid, the fluid path and the source of pharmaceutical are removably connectable. The valve assembly provides flow control through the fluid delivery set such that operator contact with the fluid delivery set is not required after connection of the source of pharmaceutical to the fluid delivery set.

    摘要: The present invention provides an injection system and a pump system for use therein for pressurizing a liquid medium for injection into a patient. In general, the pump system comprises a pressurizing unit having at least one chamber. Each chamber has disposed therein a pressurizing mechanism to pressurize liquid medium within the chamber. Preferably, the pressurizing mechanism positively displaces the liquid medium through generally linear motion of the pressurizing mechanism within the chamber. Through reciprocating linear motion of the pressurizing mechanism (for example, a piston), the liquid medium is alternatively drawn into the chamber from a source of liquid medium (for example, a container) and forced out of the chamber under a desired pressure. Each chamber comprises an inlet port and an outlet port. The pump system also preferably comprises an inlet port check valve which allows the liquid medium to flow into the chamber through the inlet port, but substantially prevents the liquid medium from flowing out of the chamber through the inlet port. Likewise, the pump system preferably comprises an outlet port check valve which allows pressurized liquid medium to flow out of the chamber through the outlet port, but substantially prevents the liquid medium from flowing into the chamber through the outlet port. Each inlet port is connected to a source of liquid medium. Each outlet port is connected to a common outlet line or channel leading to the patient.

    摘要: The present invention provides a syringe and a powered injector for use therewith in which the syringe is attachable to a powered drive member of an injector over a range of relative axial positions of the syringe plunger and the drive member. The syringe comprises a plunger, and a plunger extension connected thereto and extending rearward from the plunger, such that the syringe may be operated manually or by a powered injector. In one embodiment, the plunger extension comprises a plurality of plunger attachment members located over a range of axial positions on the plunger extension. Each of the plurality of plunger attachment members is adapted to form a releasable attachment with at least one cooperating injector attachment member on the powered drive member. In another embodiment, the plunger extension of the plunger comprises at least one plunger attachment member which is adapted to form a releasable attachment with each of a plurality of corresponding injector attachment members located over a range of axial positions on the powered drive member. By providing a plurality of cooperating attachment members over a range of axial positions on at least one of the plunger extension or the powered drive member, operative attachment of the plunger and the drive member is made possible at multiple axial positions of the plunger (within the syringe) for each axial position of the drive member over at least a range of possible plunger axial positions. Attachment of the plunger to the drive member at various axial positions of the plunger thus becomes an easier task than previously possible with current powered injector systems.

    摘要: An angiographic injector device for use in x-ray photography for delivering contrast media to a patient at controlled rates and pressures. A processor elicits injection parameters from an operator or a pre-programmed injection module, and on the basis of the injection parameters, calculates appropriate control signals for use in a closed-loop servo system to actuate the plunger of a syringe containing the contrast media. Injection parameters includes flow rate, volume, duration, pressure limit and rise-fall time of flow rate. The device also includes control circuits for inhibiting the injection device in response to a contrast media pressure limit, failure in the processor or injection control system, or upon reaching a predetermined volume of injected media. A mechanical stop member cooperates with the control circuit for blocking movement of the syringe plunger upon reaching the predetermined injected volume. Further, the device includes a self-test feature for checking the status of operational components thereof and a self-calibration feature for calibrating the servo system and position monitors. To improve reliability and to provide immunity from data corruption due to line power interruption, injection parameters are stored in battery-powered primary and secondary memories, and are compared and verified prior to an injection. To assist in coordinating an injection in synchronism with cardiac activity, the device monitors the ECG waveform of the patient's heart and injects a small bolus of contrast media at a given interval, such as the distolic interval. An interface also is provided for providing remote transfer of status and control information with the angiographic injector device.
