摘要： The fluid delivery system (10) generally includes a source of injection fluid (6), a pump device (30), a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device. The fluid path set includes a multi-position valve (50). The fluid control device is operatively associated with the fluid path set and includes a valve actuator adapted to operate the multi-position valve. The valve actuator is adapted to close the multi-position valve to isolate the pump device from a patient and stop flow of the injection fluid to the patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The valve actuator is generally adapted to selectively place the pump device in fluid communication with the source of injection fluid for supplying the injection fluid to the pump device and the patient.

摘要： A fluid injection apparatus for use with a syringue includes an injector and a pressure jacket assembly associated with the injector. The injector includes a housing defining a central opening and a drive piston extendable through the central opening for imparting motive forces to a syringe plunger disposed within the syringe. The pressure jacket assembly includes a pressure jacket and at least one support arm associated with and extending outward from the housing. A syringe retaining member is attached to the at least one support arm. The syringe-retaining member defines a syringe receiving slot for receiving at least a portion of the syringe. A light source is located on the support arm and faces the pressure jacket for illuminating the syringe. The syringe includes an alignment flange preferably defining a bulged air bubble-viewing window. The alignment flange is used to properly orient the syringe in the pressure jacket.

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 multi-fluid injector system and methods of operation thereof are presented. One embodiment of such a fluid injector system includes a powered injector, a pressure jacket support, a syringe pressure jacket, and a syringe. The pressure jacket support includes a front plate and a rear plate. The rear plate is connected to the injector and the front plate is spaced from the rear plate and defines a slot. The syringe pressure jacket has a proximal end pivotally connected to the rear plate so that a distal end of the pressure jacket pivots relative to the front plate. The syringe has a syringe body with a distally extending discharge conduit. With the syringe disposed in a barrel of the pressure jacket, pivotal movement of the pressure jacket results in the distal end thereof pivoting toward the front plate to place the discharge conduit within the slot in the front plate.

The fluid path is adapted to connect the pressurizing device to a patient via a catheter including a balloon and inserted in the patient. The control unit is operable to control the fluid delivery system. In operation, the control unit selectively actuates the fluid delivery system to operate in a fluid injection mode or in a balloon inflation mode. In the fluid injection mode the pressurizing device delivers fluid to the fluid path for a fluid injection procedure. In the balloon inflation mode, the pressurizing device delivers fluid to the fluid path for inflating the balloon associated with the catheter. An operator control may be connected to the control unit for controlling the fluid delivery system and may be a handheld device.

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 algoπthm associated with a computer.
