    摘要： An adapter includes a syringe carrier adapted to seat at least a portion of the syringe. The syringe carrier includes at least one rearward facing abutmer member to abut at least one forward facing surface on a syringe. The syringe carrie includes an opening therein to allow a drive member of an injector to communicate forward force to the plunger through abutment without connective engagement between the drive member and the plunger. The adapter further includes a releasable mounting mechanism positioned to the rear of the syringe carrier to mount the adapter in a desired position relative to the front wall of the injector. An adapter includes a first section and a second section that are rotatable relative to each other about a hinge axis generally perpendicular to a longitudinal axis of the adapter. An adapter includes a first section and a second section that are generally the same in construction, the first section and the section being connectable to form a syringe carrier to seat at least a portion of the syringe.

    摘要： A syringe for use with a powered injector to inject a fluid into a patient includes at least a first indicator positioned on the syringe at a predetermined axial position. The distance between a rearward surface of the first indicator and a predetermined position on the powered injector provides information about the syringe configuration. The first indicator can, for example, be a rear surface of the attachment flange. An injector system includes a powered injector having a drive member and at least one sensor for detecting energy. The injector system also includes a syringe having at least a first indicator positioned on the syringe at a predetermined axial position. The energy detected by the sensor is determined by the axial position of the indicator when the syringe is attached to the powered injector. The axial position of the indicator thereby provides information about the syringe configuration.

    摘要： A solution pumping system includes a compressible pump cassette having front and rear body members, and an elastomeric diaphragm positioned therebetween. The front and rear body members are joined to each other for limited, relative movement, which movement effects compression of the diaphragm. The pump cassette is removably positionable in a pump driver of the system, which can be configured to effect compression of the cassette for use. In this way, the desired compression of the diaphragm during use can be achieved, while avoiding problems associated with compression set or load decay during storage of the cassette prior to use.

    摘要： Methods for capacitance volume correction in fluid-containing expandable bodies and associated fluid pathways are disclosed. The methods may be applied in fluid delivery systems used to supply fluids to patients during radiographic imaging procedures, including angiography. The methods control delivery of fluid to a downstream process, including providing a fluid-delivery expandable body and a pressurizing element in fluid communication with the downstream process, pressurizing the expandable body by moving the pressurizing element in the expandable body to reduce volume therein, determining an over-travel distance for the pressurizing element, and ceasing movement of the pressurizing element after allowing the pressurizing element to over-travel the over-travel distance to compensate for expansion of the expandable body under pressure. The expandable body may be a syringe and the pressurizing element may be a plunger disposed within the syringe. Movement of the pressurizing element may be controlled by an algorithm associated with a computer.

    摘要： A method of capacitance volume correction in fluid-containing expandable bodies and associated fluid pathways is disclosed for application in fluid delivery systems used to supply fluids to patients during radiographic imaging procedures including angiography. One embodiment is directed to a method of controlling delivery of fluid to a downstream process, including providing a fluid-containing expandable body, including a pressurizing element and in fluid communication with the downstream process, pressurizing the expandable body by moving the pressurizing element forward in the expandable body to reduce volume therein, and ceasing movement of the pressurizing element after allowing the pressurizing element to over-travel a sufficient distance to compensate for expansion of the expandable body under pressure. The expandable body may be a syringe and the pressurizing element may be a plunger disposed within the syringe. Movement of the pressurizing element is controlled by an algorithm associated with a computer.
